We studied all cases of strabismus surgery performed at the Manhattan Eye, Ear and Throat Hospital between January 1, 1981 and June 30, 1986. Of the procedures, 106 (5.4%) were performed on patients over the age of 60 years. Strabismus in patients over age 60 represents a category of diseases which are different from those of childhood. Horizontal deviations were seen in 74% of the patients equally divided between esotropia and exotropia. Vertical strabismus was seen in 17%, and a combined vertical horizontal strabismus was seen in 9% of patients. In children, the overwhelming majority of ocular deviations are horizontal, with esotropias outnumbering exotropias. The strabismus was of adult onset in 71% of cases and of childhood onset in 29% of the patients. The etiology in the adult onset strabismus group included neuroparalytic, restrictive, sensory, and post-cataract surgery strabismus, as well as decompensated exophoria/intermittent exotropia; this was in contrast to children where the most common etiology of strabismus is innervational disturbances in fusional vergences. The major indications for surgery were diplopia and aesthenopia in 71% of cases. Diplopia is uncommon in childhood. Corrective surgery for the relief of diplopia may be enhanced with the use of adjustable sutures and postoperative prism therapy. Precise realignment is the goal of strabismus surgery in all age groups, however, the role of adjustable sutures and prisms is more important in the treatment of the functional complaints of older patients. Exploration and lysis of adhesions and scar tissue are major components of surgery on patients with restrictive strabismus.(ABSTRACT TRUNCATED AT 250 WORDS)

A new simple glare test was designed and evaluated regarding clinical usefulness and reproducibility. The ability to recognize letters of equal size and varying contrast was determined with the absence and presence of glare sources above and below the letters. Ten patients with cataract, visual acuity of at least 0.3 and glare problems, and three age matched controls were tested, as well as one patient with glare complaints and exophoria, one with lens subluxation and one with cataract and no glare problem. The test was found to be cheap and simple to produce and useful for clinical testing. Normal eyes had no detectable reduction of letter contrast sensibility with glare. All cataractous eyes had a letter contrast sensitivity without glare that was well below that of the controls and under glare conditions they all had a drop in visual function that was unrelated to their visual acuity. The reproducibility was of a magnitude similar to that of other low contrast letter tests. Our conclusion is that this test will be a valuable tool in the evaluation of cataract patients providing information not only about glare-induced visual loss but also about contrast sensitivity, separating eyes with increased intraocular light scattering from normal eyes.

Investigation of the binocular functions in 25 patients with bilateral aphakia having undergone the two cataract operations at intervals ranging from 1 to 11 years. Only in 4 patients was the unilateral aphakia corrected temporarily by contact lenses. By the alternating cover test it was found that, after the second operation, 3 patients showed an esotropia and 14 an exotropia or exophoria for distant sight and 23 an exotropia or exophoria for near sight. Over one-third of the patients not having worn any contact lenses had no simultaneous vision at the Bagolini test for distant sight and more than half of them had no simultaneous vision for near sight. There was no stereoscopic vision for distant sight in nearly 50% of the patients and no stereoscopic vision for near sight in more than half of those who had not worn any contact lenses. The early fitting of contact lenses or the immediate lens implantation in elderly patients together with the prescription of spectacles for near work in the case of unilateral aphakia prevent the weakening or the loss of binocular functions.

Between 1972 and 1980 extracapsular cataract surgery was performed in 24 children, followed by implantation of an iris clip lens, after primary reconstruction of the anterior segment. Regular follow-ups were carried out at 3-month intervals. Discission of a secondary cataract was necessary in 19 cases. Visual acuity of 0.5 or more was achieved by 19 children. An orthophoria or exophoria was also found in 19 children with positive depth perception after a minimum of 2 and a maximum of 9.5 years' observation.

We report a 44-year-old woman with intermittent left exotropia of 35 prism diopters at distance who initially exhibited alignment of both eyes after bilateral laser in situ keratomileusis (LASIK). The exophoria was not preserved due to myopic regression in the dominant eye. An uneventful LASIK treatment was performed to correct -11.00 -0.50 x 130 in the right eye and -13.50 -1.50 x 145 in the left eye. The aim was to achieve emmetropia in both eyes. Although an examination revealed exophoria at near and distance during the 6 months following refractive surgery, the tropic aspect of the divergent deviation appeared in the right eye following the myopic regression. Laser in situ keratomileusis is an effective option to achieve binocular visual quality in myopic anisometropic patients. However, myopic regression after LASIK may disrupt the binocular visual quality.

Meares-Irlen syndrome is characterised by symptoms of eye strain, headaches and visual perceptual distortions when viewing text. The symptoms are alleviated with individually prescribed coloured filters, such as precision tinted lenses. Meares-Irlen syndrome, and the related condition of visual stress, are likely to result from hyperexcitability of the visual cortex, which can also occur in migraine. The symptoms of Meares-Irlen syndrome and visual stress are non-specific and the condition needs to be differentially diagnosed from other optometric conditions, such as refractive error, binocular vision anomalies, and accommodative anomalies. Three case reports are described of patients who consulted the author with suspected Meares-Irlen syndrome but were found to have other causes for their symptoms: posterior sub-capsular cataract, high uncorrected astigmatism, and decompensated convergence weakness exophoria. These cases highlight the need for professional eye care for people with suspected Meares-Irlen syndrome. Although this advice is stressed in literature on the well-established MRC/Wilkins Intuitive Colorimeter system, it is not always stressed in literature about other systems. This may be a cause for concern.
