Best's vitelliform macular dystrophy.

A patient with Best's vitelliform macular dystrophy in his right eye had an intact vitelliform disk and drusen of the optic papilla. Although the foveola elevated by a few tenths of a millimeter, resolution was only slightly affected and the retinal receptors remained remarkably well-aligned, suggesting that mechanisms subserving receptor alignment still functioned. Hue discrimination and visual acuity were only slightly affected and the electroretinogram and visually evoked response showed essentially normal values. The vitelliform disk in the left eye ruptured by direct, blunt trauma. This same eye later developed subretinal macular neovascularization, as its visual acuity reduced, retinal sensitivity decreased, receptor orientation showed abnormalities, and hue discrimination became less efficient; the electroretinogram and visually evoked response remained normal.

Accommodative effects of aceclidine in the treatment of glaucoma.

In 18 patients, 2% pilocarpine, 2% pilocarpine plus tropicamide 10:1, and 2% aceclidine were tested with respect to the degree of spasm of accommodation induced by these drugs. Aceclidine had the least effect on accommodation, making it the recommended drug for use in patients with glaucoma and considerable remaining accommodation, i.e., most patients under the age of 50 years.

Genetic analysis of vergence measures in populations with varying incidences of strabismus.

Genetic parameters were contrasted for vergence amplitudes within three populations--esotropic, exotropic, and randomly selected populations-who differed in their incidence of subtypes of strabismus. In general, heritabilities for convergence exceeded those for divergence, and heritabilities for recovery points exceeded those for break points. Heritability estimates for diveregence amplitudes were significantly different for the random and esotropia populations, while convergence heritability estimates for these groups were similar. Thus, gene differences influencing divergence ability contributed to genetic variance for strabismus.

Visual parameters associated with recovered retrobulbar optic neuritis.

Visual acuity, color vision, pupillary reaction, induced Pulfrich phenomenon, kinetic fields, static fields, afterimage testing, and ophthalmoscopic evaluation were studied in nine patients with a history of retrobulbar neuritis. The most consistently reliable test for determining the presence of an old optic nerve defect in these patients was meridional 0 to 180 degrees static perimetry. There was a uniform decrease in brightness discrimination to either side of the foveal peak.

Resection of both medial rectus muscles in organic convergence insufficiency.

Six patients with a prolonged history of severe muscular asthenopia caused by persistent convergence insufficiency underwent resection of both medial rectus muscles. A temporary consecutive esotrapia occurred in each instance and was controlled with prisms. Five weeks after surgery the consecutive esotropia had disappeared in all but one patient who still required prismatic correction for distance fixation. All patients experienced relief from their symptoms. Whereas orthoptic training is useful in most cases of convergence insufficiency a resection of both medial rectus muscles should be considered in persistent cases especially with an associated weakness of accommodation.

Horner's syndrome with ipsilateral accommodative paresis.

In a 12-year-old girl with Horner's syndrome and an ipsilateral accommodative paresis, intravenous administration of edrophonium chloride improved the accommodative defect on several occasions, which suggested a possible relationship to myasthenia gravis. Additional testing of the accommodative paresis revealed some of the characteristics of Adie's syndrome and suggested a relationship to pupil-sparing Adie's syndrome.
