Early surgical alignment for congenital esotropia.

To provide sufficient numbers of patients varying in age of initial adequate surgical alignment for congenital esotropia, 162 patients managed by seven ophthalmologists in three countries were personally examined by the author and the results compiled for a clinical study. From this population group, 106 patients were chosen who had reliable answers, satisfactory alignment, and an ophthalmologist's confirmation examination of the congenital nature of the problem by at least 1 year of age. The results of sensory testing showed that those adequately aligned by the age of 6 months vs 12 months vs 24 months were not statistically different, but those patients aligned after 24 months of age demonstrated a significantly lower percentage with evidence for binocularity (P less than 0.001). Surgical alignment in the congenital esotropic patient should be accomplished by 2 years of age to attain the highest yield of binocular function.

Experience with extended wear hydrogel lenses for aphakia.

Nineteen of 23 aphakic eyes were able to wear a hydrogel soft lens for 3 to 14 months (average, 8.32 months). About half of the patients in the study had failed to tolerate all other types of contact lenses. The most annoying problem with the hydrogel lens was the development of surface deposits, which required cleaning or replacement of the lenses. Despite this drawback, the lenses were enthusiastically accepted and provided satisfactory vision for all the patients, several for their only functioning eye.

Results of 100 consecutive anterior chamber implants.

Using an anterior chamber lens made from Perspex CQ we began a series of 100 consecutive implantations in 1976. Iris tucking of at least one foot of the lens was found in 19 cases, however this complication was not associated with iritis or glaucoma at the time of the study. Tenderness over the operative eye was rare and did not appear to be a significant problem. There were no cases of the uveitis-glaucoma-hyphema syndrome. For an average follow-up time of 12.3 months, 90% of the eyes without pre-existing retinal pathology demonstrated 20/40 or better visual acuity.

The development of corneal astigmatism in contact lens wearers.

In this study of 131 eyes, a comparison of the corneal astigmatism present before wearing hard contact lenses was made with that found after several years of wear (mean length of time: 4.4 years). The eyes were divided into 3 groups according to their ocular rigidity measurements. Statistical analysis of these groups showed that eyes with low ocular rigidity developed a high incidence of with-the-rule astigmatism change and that, furthermore, this change was of significant amount (twice that developed by eyes in the other groups). It was notable that all of the eyes that developed more than 1 1/2 diopters of astigmatism had low ocular rigidity.

Early surgical alignment for congenital esotropia.

To provide sufficient numbers of patients varying in age of initial adequate surgical alignment for congenital esotropia, 154 patients managed by seven ophthalmologists in three countries were personally examined by the author and the results compiled for a clinical study. Examiner bias was minimized by having the examination performed without prior knowledge of the clinical history and the tests were standardized in both method of examination and test devices. From this population group 106 patients were chosen who had reliable answers, satisfactory alignment and an ophthalmologist's exam of the congenital nature of the problem by at least one year of age. The results of sensory testing showed that those adequately aligned by the age of 6 months versus 12 months versus 24 months were not statistically different, but those patients aligned after 24 months of age demonstrated a significantly lower percentage with evidence for binocularity (p less than .001).

The timing of surgical alignment for congenital (infantile) esotropia.

At this time, the beneficial effect of accurate alignment by age 2 in congenital esotropia has been well established by clinical and laboratory studies. There is, however, only scanty clinical evidence that alignment before age 1, much less before 6 months of age, may yield a better quality of binocularity (i.e., refined stereoacuity) than alignment by age 2. Pitfalls of very early alignment are present. In addition, the ophthalmologist must be vigilant in following the initially aligned patient and be ready to treat vertical motor defects, amblyopia, and acquired refractive errors. The need for additional horizontal surgery after initial alignment is also common. The optimum result in the surgical treatment of congenital esotropia generally shows binocularity that is within the confines of a monofixation syndrome, and refined stereoacuity remains an elusive target and a rare outcome, no matter at what age the alignment is achieved.

Infection following strabismus surgery.

Sixty-three strabismus surgeons were surveyed regarding the incidence of infection they found following strabismus surgery and their use of preoperative and postoperative antibiotics to prevent or treat such infections. Cellulitis was rare (1 per 1,900 cases) and endophthalmitis was even rarer (1 per 30,000 cases). Infection was not entirely prevented by either preoperative or postoperative topical antibiotics. Twelve surgeons reported using no antibiotics but did not report higher rates of infection than those who did use them.
