Corneal dellen in the limbal approach to rectus muscle surgery.

A retrospective study of 170 cases of horizontal rectus muscle surgery performed during the years 1969 and 1970 at the University of Illinois Eye and Ear Infirmary revealed a 6-5 per cent incidence of dellen with the limbal approach to the muscle and a 2-2 per cent of incidence of dellen with the nonlimbal or direct approach to the muscle. This was significant to the 5 per cent level of confidence by the chi2 test. We feel that this finding of an increased incidence of dellen with the limbal approach complements the current theory of desiccation as the cause of corneal dellen. We do not recommend abandonment of the limbal approach to rectus muscle surgery because of this finding, but suggest that surgeons scrutinize more carefully their postoperative patients for dellen. If dellen do not occur careful trimming of the conjunctiva to avoid bunching and thickening may perhaps eliminate them.

Aqueous and serum lysozyme values in experimental uveitis in rabbits.

The purpose of this study was to determine what happens to normal aqueous lysozyme levels during experimentally induced uveitis. Horse-serum-induced uveitis increased the average rabbit aqueous lysozyme value (0.9 mug per milliliter) to 13.8 mug per milliliter, but did not elevate the average serum lysozyme value (4.0 mug per milliliter). These findings suggest that ocular inflammation alone is not sufficient to elevate the serum lysozyme level.

Type 1 and type 2 herpes simplex uvietis in immune rabbits: importance of pure virus preparation.

Systemic immunization with type 1 herpes simplex virus (HSV) protected rabbits from developing uveitis when they were challenged intravitreally with either purified type 1 or purufied type 2 HSV. But when an HSV preparation contaminated with a nonviral foreign antigen (fetal calf serum) was used for both systemic immunization and challenge, the immunization against HSV failed to exert a protective effect because the fetal calf serum had produced a nonviral immunologic reaction in the uveal tract. This clearly indicates the importance of preparing virus properly for use in experiments of this nature.

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.
