ABSTRACT
We report a case of bilateral loss of pupillary light reflex and accommodation following 360° peripheral retinal laser therapy. A 24 years old male underwent prophylactic laser barrage for peripheral retinal lattice degenerations. Soon after the procedure, he developed bilateral loss of pupillary light reflex and accommodation. The patient faced difficulty while doing near work. On instillation of 0.125% pilocarpine, both pupils demonstrated the phenomenon of denervation supersensitivity. Damage to the short ciliary nerves was the most likely mechanism responsible for this adverse outcome

BACKGROUND: We undertook this study to demonstrate the incidence of vitreoretinal dystrophies in a Mexican population. METHODS: This was a retrospective, observational, descriptive, transverse study. We analyzed the files of patients treated at the Retina Department of a medical center for state employees (ISSSTE) from January 1991 to December 2006 to obtain the incidence of vitreoretinal dystrophies. RESULTS: We studied 36,300 patient files. We found an incidence of 0.008% for familial exudative vitreoretinal dystrophy, 0.008% for X-linked juvenile retinoschisis, 0.005% for Wagner disease and 0.005% for Goldmann-Favre disease. We present here a representative case of each type of dystrophy. CONCLUSIONS: Vitreoretinal dystrophies are uncommon diseases and are difficult to diagnose. Even though their incidence is low, the poor evolution to blindness requires identification of early signs in order to offer timely and opportune treatment.

A doença de Wagner é uma forma muito importante e por vezes esquecida de patologia vitreorretiniana. O mesmo ocorre com a síndrome de Stickler, uma forma mais completa da doença. Säo estudados três casos com especial atençäo as complicaçöes: alta miopia, descolamento da retina, catarata e glaucoma

The autors show the first case in which the parabulbar bailon is utilized in Brazil. They take some observations about procedure, and think to be useful in well selectioneted cases
