Afferent pupillary defects in amblyopia.

We detected mild afferent pupillary defects with the "swinging flashlight" test in 4 out of 45 amblyopic patients. Our study was designed to minimize the effect of observer bias and to control for the difficulty of testing the pupils in young children. We found afferent defects in both strabismic and anisometropic amblyopes. There was no apparent relationship between pupillary response and visual acuity: afferent defects were noted in association with better than 20/100 vision in three cases but were absent in a majority of patients with profound visual loss. Vision was improved by occlusion therapy in two amblyopes with pupillary abnormalities. We regard the occurrence of afferent pupillary defects as evidence for a physiological disturbance at the retinal level in at least some cases of amblyopia. Our findings suggest that the extent of retinal involvement in amblyopic eyes is independent of reduction in acuity, to which primary cortical abnormalities may contribute as well.

Transection of the inferior rectus muscle.

Four cases of isolated inferior rectus transection secondary to trauma are presented. The clinical and CT scan findings are illustrated. The CT scan findings are very useful in the surgical management and prognosis of these cases.

Necrotizing scleritis following strabismus surgery for thyroid ophthalmopathy.

Necrotizing scleritis with inflammation of the right eye developed after bilateral eye muscle surgery for thyroid ophthalmopathy. Debilitating pain, delay in onset, and involvement of the sclera distinguish this condition from anterior segment ischemia. The surgery may have acted as a nonspecific trigger in an eye at risk for scleritis. Necrotizing scleritis has occurred infrequently after other types of eye surgery but, to our knowledge, has not been previously reported as a complication of eye muscle surgery.

The surgical treatment of undercorrected esotropia: an evaluation of the effect of recession of the medial rectus muscle 13.5 mm from the limbus.

Nineteen patients with residual esotropia following conventional maximum horizontal recess-resect surgery were treated by further recession of the medial rectus muscle to a point 13.5 mm from the limbus. Six of these patients also underwent an 8-mm resection of the ipsilateral lateral rectus in addition to the medial recession. Eighteen of the patients achieved a good to excellent cosmetic result in the primary position. One patient was markedly overcorrected probably secondary to an unwarranted lateral rectus resection. Most of the patients showed some mild limitation of adduction, but this was generally not a significant cosmetic or functional defect. The degree of limitation seen was no greater than that which has been observed in similar patients treated by marginal myotomy. Recession of the medial rectus muscle 13.5 mm from the limbus seems to be a safe and effective method of treating surgically undercorrected esotropia.
