As a child Mr. Lyman suffered with a congenital eye condition involving Nystagmus and Strabismus. The examining physicians identified and discussed the nature of these conditions. According to the physicians, Nystagmus is a medical condition associated with "jerky movement" of the eyes. The eyes do not stay straight in place, but can jump side to side. Strabismus is a medical condition associated with abnormal muscle eye function. According to Mr. Lyman, as a child he suffered with severely crossed eyes, which resulted in him undergoing corrective surgery at age five.
Notably, even with corrective surgery and use of corrected lenses (eye glasses and/or contact lens) Mr. Lyman experienced as a child poor vision (myopia), which did not allow for complete restoration of eye sight. Mr. Lyman wore glasses until age 16. He was then fitted with contact lenses. As early as June 19, 1997, Mr. Lyman presented with a best corrected eye vision of 20/70 in each eye. He kept the same contact lens prescription from the time he was 16, until after suffering the work-related injury of May 24, 2002.
Mr. Lyman's poor vision prevented him from performing certain activities prior to May 24, 2002, and rendered him unable to qualify for military service. Yet, Mr. Lyman could do many things and was able to work. In order to read and perform eye-hand coordination activities, he adjusted to the impaired vision by getting closer to items. Additionally, prior to May 24, 2002, he managed to pass the vision test associated with having a driver's license, and obtained a driver's license, although he presented with a vision that is considered insufficient to obtain a driver's license. Elliot L. Korn, M.D., who is an ophthalmologist that the employer and insurer secured for the purpose of performing an independent medical examination, noted that a corrected vision of 20/40 is generally considered the minimal vision necessary for an individual to pass and obtain a driver's license from a DMV office. Although Dr. Korn acknowledged that, at times examiners will permit a person to pass the test and obtain a driver's license with a 20/50 or 20/60 vision.
In April 2003 Mr. Lyman presented to David M. Pierce, OD for purpose of securing a prescription for contact lens. At the time of this visit, Mr. Lyman underwent an eye examination, which allowed Dr. Pierce to provide Mr. Lyman with a "best corrected visual acuity" of 20/70 for both the right and left eyes. And Mr. Lyman's myopia was noted to be -7.00 in each eye. According to Dr. Pierce, this initial examination allowed him to fit Mr. Lyman with "contacts that were successful both in fit and visual acuity."
In addition, Dr. Pierce noted that, at the time of the April 2003 examination, Mr. Lyman did not suffer from cataracts. (The medical evidence indicates that cataracts involve a medical condition in the eyes, which causes cloudiness of vision, and can produce glare and cause the individual to experience difficulty seeing to read and drive, and to do activity that requires vision.)
Subsequent to undergoing hyperbaric oxygen treatment sessions, however, Mr. Lyman began to experience deterioration in his eye sight. In light of this deterioration in eye sight, Mr. Lyman returned to see Dr. Pierce on July 28, 2004. At the time of this examination, Dr. Pierce noted that Mr. Lyman presented with increased myopia, which had changed from -7.00 to -10.75 in each eye; and Mr. Lyman had developed nuclear sclerotic cataracts. (According to the physicians, cataracts or age-related nuclear cataracts is a medical condition involving the opacification of the natural lens system - "a general clouding of the lens system.") Notably, at the time of this visit, Dr. Pierce expressed concern that the hyperbaric oxygen treatment or the high doses of antibiotics had caused Mr. Lyman to develop the cataracts and that Mr. Lyman will need to undergo cataract surgery.
Mr. Lyman's eye sight continued to deteriorate, and hindered his ability to work and perform various activities, including driving a motor vehicle. In September 2004 Dr. Pierce determined that, even with corrected acuities, Mr. Lyman's vision no longer allowed him to qualify for a driver's license. Further, and based on his review of medical literature, Dr. Pierce causally related the loss of vision and development of "extreme myopia and cataract formation" to the dosage and duration of use by Mr. Lyman of the medication Bextra. Dr. Pierce further warned that, "if Mr. Lyman were to stay on this medication he would develop significant cataract development increased myopia and possible legal blindness."
Thereafter, the employer and insurer referred Mr. Lyman to Elliot L. Korn, M.D., who is an ophthalmologist, for an examination and evaluation. In light of his examination and evaluation of Mr. Lyman, Dr. Korn opined that Mr. Lyman presented with bilateral cataracts, posterior vitreous detachments in both eyes, and ptosis in both eyelids. Additionally, Dr. Korn noted that Mr. Lyman demonstrated a corrected vision with contact lens of 20/200 in both eyes, as compared to a vision of 20/70 in 1997 at its best.
Notably, in examining the cause of the cataracts and worsening of the myopia, Dr. Korn, in pertinent part, propounded the following comments:
To summarize, I feel that Mr. Lyman's cataracts is possibly consistent with his age, congenital esotropia and surgery, and congenital nystagmus. Although these may not be complete factors, his injury in which he had acute inflammation and
infection of his hip, which may cause to continue more inflammatory changes in the body, causing possibly a more rapid progressive in the lens.
I cannot be certain of any of this, because I have many patients who have not had any infections or problems, which have had developed cataracts much more quickly. I have performed cataract surgery on 17 years old people, who have had no other medical problems. Basically, it is my opinion that the cataract formation is not related to the Bextra or Hyperbaric oxygen therapy.
In light of Dr. Korn's evaluation and opinion, the employer and insurer denied liability associated with the development of cataracts and increased loss of vision, and declined to provide Mr. Lyman with medical care for treatment of the cataracts and visions loss. Mr. Lyman did not obtain medical care for treatment of and removal of the cataracts in the calendar years 2004, 2005, 2006, or 2007.
On or about March 24, 2007, the employer and insurer sought and obtained a supplemental examination and evaluation of Mr. Lyman by Dr. Korn. At the time of this examination, Dr. Korn noted that Mr. Lyman's corrected vision was 20/300 in both eyes. Additionally, Dr. Korn noted that Mr. Lyman presented with bilateral ambylopia secondary to nystagmus, mild cataracts and mild ptosis.
On or about November 17, 2007, Mr. Lyman presented to Rolfe A. Becker, M.D., who is a physician practicing in the specialty of ophthalmology and is affiliated with Cokingtin Eye Center, for an examination and evaluation. In light of his examination and evaluation of Mr. Lyman, Dr. Becker recommended that Mr. Lyman undergo surgical cataract removal. Additionally, in recommending this surgery, Dr. Becker expressed hope that Mr. Lyman would experience improvement in his vision, and possibly achieve his pre-injury vision of 20/70 in both eyes. However, without the surgery, Dr. Becker expressed concern that the cataracts would cause Mr. Lyman's vision to continue to deteriorate.
In addressing the cause of the cataracts and the likelihood of success associated with the recommended surgery, Dr. Becker propounded the following opinion:
On examination, Mr. Lyman had best corrected distant vision of 20/100 in each eye and near vision of Jaeger 10-12. He wears contact lenses with a high myopic correction. The other findings of significance include nystagmus and dense nuclear cataracts. Intraocular tension was normal (16 OD, 17 OS), as was muscle balance and confrontation fields. The fundi appeared intact.
Mr. Lyman described his vision change as progressively decreasing after his hyperbaric treatments. He states he was advised that his vision could get blurry, but would recover. It did not improve and, in fact, deteriorated. There was no specific comment about his vision after the use of Bextra.
The literature on hyperbaric treatment stated that a myopic shift can take place, but usually returns to pre-treatment level. However, in some cases, cataract
changes occur and progress. Mr. Lyman's cataracts, which are dense nuclear opacities or age-related type, are consistent with those described in the literature.
The literature is sparse regarding Bextra. It includes as adverse reactions, blurred vision and cataract, but only in less than 0.2 % of cases. While I have inquired from the manufacturer for more detail, none has been forthcoming.
It is my medical opinion that Mr. Lyman has developed age-related nuclear cataracts consistent with the type described following hyperbaric treatment. I do not think Bextra has played a role in his visual disturbance.
Mr. Lyman's vision history suggested abnormal findings from birth, including reduced vision and nystagmus. With removal of the cataracts, which I strongly recommend, he should return to pre-cataract status, probably in the range of 20/60 to 20/70.
In a supplemental report dated January 14, 2008, Dr. Becker propounded the following opinion:
Mr. Lyman has pre-injury conditions which accounted for his poor vision (20/70 in each eye). These include nystagmus and strabismus. Cataracts were not present. It is still my medical opinion that the hyperbaric treatments caused lens changes which have progressed with reduced vision.
Since my December 7, 2007 report, I did receive a response from the manufacturer of Bextra. They gave reference to literature ... that states conjunctivitis and blurred vision are the two main ocular adverse effects of this medicine but usually self resolve. In studies done ... several adverse events could occur in 0.1-1.9 % of patients. In my medical opinion, Bextra did not have any adverse effect causing Mr. Lyman's visual disturbance.
On or about January 14, 2008 the employer and insurer, by counsel, authorized Mr. Lyman to undergo treatment with Dr. Becker for removal of the cataracts. Thereafter, Mr. Lyman, by counsel, responded to the employer and insurer's letter authorizing treatment with Dr. Becker, stating that he was prepared to undergo the surgery, but "only when he receives his back TTD and an agreement of the payment of TTD until he has reached maximum medical improvement.
Subsequently, the employer and insurer took the position that the employee was unreasonably refusing medical care for treatment of the cataracts. Eventually, following discussion between counsel, and determining that Dr. Becker does not perform this surgery, the parties agreed to have Mr. Lyman undergo the cataract removal surgeries with Christopher S. Banning, M.D. who is a physician practicing in the specialty of ophthalmology and is affiliated with Cokingtin Eye Center and a colleague of Dr. Becker. (In agreeing to authorize this surgery, the employer and insurer continued to deny medical causation, and noted that it would be raised as an issue at a final hearing.)
In September 2008, Mr. Lyman presented to Dr. Banning for evaluation and consideration of surgery. At the time of this initial evaluation by Dr. Banning, Mr. Lyman's best vision was noted to be 20/200 in both eyes with eye pressures of 11 and 12. Pupil motility testing was unremarkable. Mr. Lyman had slow horizontal pendular nystagmus of both eyes. There was moderate upper lid ptosis of both eyes. There was moderate blepharitis of both eyes. The corneas were clear with extremely deep anterior chambers. Dr. Banning found dense nuclear sclerotic cataracts. The peripheral retinas appeared intact. Dr. Banning mentioned to Mr. Lyman that the congenital nystagmus with high myopia would cause a limited best corrected vision and increase a risk for retinal detachment.
On or about October 1, 2008, and October 14, 2008, Mr. Lyman underwent surgery for removal of the cataracts, with the surgeries performed by Dr. Banning. Subsequently, on or about November 14, 2008 Dr. Banning released Mr. Lyman from his care.
In a supplemental report dated December 30, 2008, and in response to questions propounded to him from Mr. Lyman's attorney following the surgeries involving removal of the cataracts, Dr. Becker propounded the following comments:
Question \#1: The visual acuity following surgery for cataract removal in both eyes was 20/100 in each eye. Mr. Lyman was last seen on November 14, 2008 with these visions. Since it has been a short while for him to readjust to seeing after cataract surgery, there may be some improvement with time, but that would take weeks to months before I can answer that question.
Question \#2: There was no unusual or new significant finding following cataract surgery that had not been discussed or reported prior to surgery.
Question \#3: It is my opinion that Mr. Lyman has a stable situation with regard to his vision. As you know, he had poor vision prior to any cataract disturbance and he should return to a similar vision status and pattern as he adapts to his new situation. The prognosis is stable without any anticipation of a progressive or new problem or any specific deterioration. Obviously, with his genetic history of nystagmus and poor vision, there can be some deterioration with time and age and therefore, one has to be cautious to say that he will have no trouble, but at the same time, based upon post operative findings, I have nothing significant to report.
Question \#4: With regard to hyperbaric oxygen and the development of cataracts, it is still my opinion that the hyperbaric oxygen therapy contributed to the development and progression of the cataracts which was initially reported and discussed.
Carmen Munday testified as a representative of the insurer. One significant purpose of the testimony concerned the issue of whether the insurer had offered medical treatment to Mr. Lyman, which he refused. Ms. Munday admitted that there were no agreements between Allmon Construction and Missouri Employers Mutual so that Allmon delegated its right to select medical providers to Missouri Employers Mutual.
Ms. Munday admitted that Dr. William Campbell had recommended to Missouri Employers Mutual that it refer Mr. Lyman to a rheumatologist. Dr. Woodward also recommended a referral to a rheumatologist for the same reason. The purpose of the referral would be to determine whether the use of Bextra or the hyperbaric oxygen caused the development of cataracts. Missouri Employers Mutual only looked to Ferrell Duncan Clinic in Springfield to determine if rheumatologists were available and then it dropped the search. In addition, Ms. Munday admitted that Dr. William Ricci had recommended that Mr. Lyman see a pain management specialist. And Munday admitted that the employer and insurer did not follow up upon the request.
In addition, Ms. Munday acknowledged that the employer and insurer did not offer to pay for cataract removal in the calendar years 2004, 2005, 2006, or 2007. Then, in January 2008, according to Ms. Munday, the insurer, through legal counsel, offered to send Mr. Lyman to Dr. Christopher Banning for cataract surgery. However, Ms. Munday did not have any personal knowledge of a specific referral to Dr. Banning in January 2008. And Ms. Munday acknowledged that, in July 2008, the insurer was unsure whether Dr. Banning would perform the recommended surgery for Mr. Lyman in context of the case involving workers' compensation.
P. Brent Koprivica, M.D., who is a physician with certification in the specialties of emergency medicine and preventive medicine in the subspecialty of occupational medicine, testified by deposition in behalf of the employee. Dr. Koprivica performed an independent medical examination of the employee on December 16, 2005. At the time of this examination, Dr. Koprivica took a history from Mr. Lyman, reviewed various medical records, and performed a physical examination of him. In light of his examination and evaluation of Mr. Lyman, Dr. Koprivica opined that, on May 24, 2002, Mr. Lyman sustained a work-related injury involving a fall off a ladder, which resulted in him suffering a left femoral neck fracture. Further, in noting that the injury involved treatment in the nature of an open reduction and internal fixation, which resulted in Mr. Lyman developing osteomyelitis with possible avascular necrosis of the femoral head, Dr. Koprivica opined that the injury caused Mr. Lyman to suffer intractable left hip pain, which impacted him severely.
In addition, Dr. Koprivica opined that, as a consequence of this May 24, 2002 injury, Mr. Lyman developed deep vein thrombosis, which complicated post-surgical treatment. And Dr. Koprivica opined that the injury to Mr. Lyman's left hip caused him to suffer mechanical back pain, resulting in him suffering severe degenerative disk disease of the lumbar spine at the level of L5-S1. In explaining this latter opinion, Dr. Koprivica propounded the following comment:
I felt that the development of the back pain followed as a direct and natural consequence of the direct injuries he had sustained to the left hip and the altered gait and weight bearing that arose because of that permanent injury.
In discussing his physical examination of Mr. Lyman during the taking of his deposition, Dr. Koprivica propounded in pertinent part, the following testimony:
Q. What did you find upon physical examination?
A. He was very unsteady because of the problems with not being able to symmetrically weight bear. He could not lie supine because of the left hip pain.
Although I could not do supine straight leg raising, I felt that Waddell's test were appropriate. I didn't believe he was exaggerating. I thought it was on a structural basis that he presented. He had severe atrophy of the left leg compared to the right. The definition of severe atrophy, again in the guides, is if there is a 3 centimeter or greater difference from one leg to the other.
In this case, he had 3 centimeters of difference in the thigh area with the right leg being bigger than the left. The left is the one he's not using, so that's going to lead to the atrophy.
Q. And that's obvious an objective finding?
A. That's correct. He had a healed scar in the area of the left hip where he had internal fixation and then had the surgical drainage procedures. He had a severe relative deficit of motion of the left hip compared to the right. If you look, his forward flexion was to 145 degrees on the right, but only 48 degrees on the left.
Again, if we do that relative percentage loss, where you take 145 minus 48 and divide it by 145 , we're above the 60 percent range. And then I have the relative number in my report, but he has loss of motion in the left hip.
Neurologically, I thought he was intact. So I didn't believe any of the deficits in the left lower extremity were related to spinal pathology producing a neurological deficit; I thought it was mechanical from problems with the hip. He couldn't squat. He couldn't toe or heal ambulate. There was no evidence of any pathology higher up in the spine. That's the Babinski Clonus testing, looking to see if there's any compression on the spinal cord or brain lesion that's causing the deficit. There was no evidence of that.
In addressing the question of future medical care, Dr. Koprivica opined that "it is medically likely that [Mr. Lyman] will eventually require a total hip arthroplasty." And Dr. Koprivica notes that the May 24, 2002 injury resulted in Mr. Lyman suffering an infection to the bone, which Dr. Koprivica notes in his deposition testimony, is considered a "lifetime infection' and presents a concern about recurrence of infection, even if presently under control.
According to Dr. Koprivica, as a consequence of the May 24, 2002 accident, Mr. Lyman is governed by permanent restrictions, "posturally to a severe degree." The permanent restrictions imposed on Mr. Lyman by Dr. Koprivica are as follows:
- Captive sitting intervals should be limited on a sustained basis to less than 30 minutes.
- Standing should be limited to less than 30 minutes at any one interval.
- Mr. Lyman will need to use a cane in order to ambulate.
- Mr. Lyman should avoid activities on uneven surfaces.
- Mr. Lyman is restricted to ground level activities.
- Cumulatively, Mr. Lyman is restricted to between two and four hours on his feet as a maximum.
- Mr. Lyman is restricted entirely from crawling, kneeling, squatting or climbing.
- Mr. Lyman should avoid bending at the waist, pushing, pulling or twisting for safety reasons.
In rendering an assessment of permanent disability attributable to the May 24, 2002 accident, Dr. Koprivica opined that Mr. Lyman was at maximum medical improvement, and had sustained the following permanent partial disabilities:
- Mr. Lyman sustained a permanent partial disability of 50 percent to the left lower extremity, referable to the hip at the 207-week level.
- Mr. Lyman sustained a permanent partial disability of 15 percent to the body as a whole, referable to the low back.
- Mr. Lyman sustained a permanent partial disability of 5 percent to the body as a whole, referable to the deep venous thrombosis involving the left subclavian and left brachial vein and the permanent changes in the venous system.
Finally, Dr. Koprivica opined that, prior to the May 24, 2002 accident, Mr. Lyman presented with a "profound disability due to visual acuity deficits." In considering whether the May 24, 2002 injury contributed to Mr. Lyman's overall visual disability, Dr. Koprivica indicated that he would defer to an appropriate expert. However, in considering Mr. Lyman's visual disability along with the restrictions causally related to the May 24, 2002 accident, Dr. Koprivica opined that "it is unrealistic to expect an ordinary employer to employ [Mr. Lyman]. In this regard, Dr. Koprivica recommended that Mr. Lyman obtain a formal vocational evaluation.
Notably, on April 12, 2008, following his receipt and review of Dr. Becker's medical report dated December 7, 2007, Dr. Koprivica amended his prior medical opinion, opining that Mr. Lyman needs eye surgery in order to address the level of his visual acuity, and that this condition renders Mr. Lyman temporarily and totally disabled. In rendering this opinion, Dr. Koprivica accepts the opinion of Dr. Becker that the use of hyperbaric oxygen is the likely substantial factor in the progression of the cataracts.
Wilbur Swearingen, CRC, who is a vocational consultant, testified in behalf of the employee through the submission of his vocational report. Mr. Swearingin performed a vocational evaluation of the employee on May 22, 2006. At the time of this evaluation, Mr. Swearingin took a history from Mr. Lyman, reviewed various medical records, performed a vocational profile using the Dictionary of Occupational Titles, and performed a vocational assessment. In performing this evaluation, Mr. Swearingen identified four factors to determine whether Mr. Lyman could be placed in the open labor market. These factors are as follows:
- Consideration of Mr. Lyman's past work
- Consideration of whether Mr. Lyman had any transferrable skills
- Consideration of whether Mr. Lyman had the ability to be educated and retrained
- Consideration of whether Mr. Lyman could work in "common jobs" (entry level employment).
In his consideration of these factors, Mr. Swearingin opined that Mr. Lyman could not return to his past work based upon restrictions set forth by either Dr. Koprivica or Dr. Woodward. Further, Mr. Swearingin opined that Mr. Lyman did not have transferrable skills, and Mr. Lyman was not eligible for retraining or similar education due to his physical pain disorders, his limitations from such, and his poor vision. Additionally, Mr. Swearingin noted that Mr. Lyman was not eligible to work in common jobs, as most of these jobs require light or medium exertion as defined by The Dictionary of Occupational Titles, which require considerable standing and walking. Very few are sedentary positions and Mr. Lyman does not sit well; and he would not have the freedom to alternate between sitting and standing in such sedentary positions.
In light of the foregoing, Mr. Swearingin opined that it was unlikely that an employer would consider hiring Mr. Lyman based upon his work restrictions, poor vision, inability to drive, limited education, and history of manual work. Thusly, Mr. Swearingin opined that Mr. Lyman was permanently and totally disabled as a consequence of the incident of May 24, 2002, considered in isolation. (Yet, in rendering this opinion, Mr. Swearingin premises his opinion on Mr. Lyman's poor vision, which he attributes to the May 24, 2002 accident, apparently without consideration of the preexisting condition's contribution to the poor vision.) In rendering this opinion, Mr. Swearingen notes that Mr. Lyman would be unable to perform any of the following work as defined by the United States Department of Labor, which included the following functions: climbing, balancing, stooping, crouching, crawling; near and far acuity, depth perception, accommodation and color vision; work in extreme weather, extreme cold, wet and humid conditions; work with vibrations from equipment or supplies; high exposed places; and explosives or toxic and caustic chemicals.
James England, VRC, who is a vocational consultant, testified by deposition in behalf of the employer and insurer. Mr. England performed a vocational evaluation of Mr. Lyman based on his review of various records and deposition testimonies, including Mr. Lyman and Dr. Woodward, but without personally interviewing him or personally observing him. In light of his evaluation, Mr. England opined that Mr. Lyman was not unemployable as a consequence of the May 24, 2002 injury, considered in isolation.
In explaining his opinion, Mr. England noted that Mr. Lyman's hip problems "certainly restrict his overall employability, but do not cause him to be unemployable. In this regard, Mr. England noted that, absent Mr. Lyman's visual difficulties, Mr. Lyman would be a "good candidate" for the use of his skill and knowledge as a construction cost estimator, building systems repair supervisor, or employee at an answer desk in a home remodeling facility. He would also be a candidate for a variety of entry-level service positions such as security work, cashiering, and counter clerk work, absent the degree of visual problems.
However, according to Mr. England, if he considered the disabilities and limitations caused by Mr. Lyman's visual impairment, in combination with the disabilities and limitations attributable to the May 24, 2002 injury, he was of the opinion that Mr. Lyman was unemployable in the open and competitive labor market.
On cross-examination Mr. England acknowledged that Mr. Lyman performed heavy work before the primary injury. And Mr. Lyman could see well enough to work, to drive, and to complete certain college work before suffering the May 24, 2002 injury. Additionally, Mr. England acknowledged that Mr. Lyman suffered deterioration in his vision after the May 24, 2002 injury, and that the deteriorated vision never returned to the pre-injury baseline. Further, Mr. England acknowledged that Mr. Lyman's visual problems, as they presently exist, are a major impediment to his ability to work.
