Two hundred and forty rabbit eyes toere exposed to focused ultrasonic radiation at either 3.5 me. or 7 me. Circumscribed chorioretinal lesion and localized destruction of the ciliary: body could, be obtained without evidence of injury to other ocular tissues. The sound beam retrodisplaces detached retinas. These observations suggest possible uses of ultrasound in retinal detachment repair, ctjc...

CLINICAL CASE This was a 15-month-old boy who had macular retinochoroidal lesions in both eyes following maternal varicella during pregnancy. DISCUSSION The scars were suggestive of congenital chorioretinal infection, but because of negative serology and the clinical picture, we believe the problems are atypical macular colobomata.

Carbonic anhydrase inhibitors may be effective to treat this condition.

Intrauterine infections are important causes of childhood blindness in both developed and developing countries. Chorioretinal scars are the most characteristic eye manifestation of a congenital or prenatal infection. The various ocular manifestations of congenital infections, summarized by the mnemonic TORCH, and recent additions to the "other" category (lymphocytic choriomeningitis virus and W...
