RESUMO
Overall study of 20 years of curative and prophylactic peripheral retinoschisis treatment in 60 cases of sex linked congenital retinoschisis. Peripheral retinoschisis was present in 36 out of 120 eyes. Twelve eyes of children under 10 years severely affected, have undergone surgery (8 improvements and 4 aggravations) and 21 cases were photocoagulated (18 stabilizations, 3 aggravations which were subsequently treated by surgery). Six cases were not treated. Aggravations after surgery or photocoagulation have always been observed in early postoperative follow-up period. The above findings bring to light the problems of treatment. An epidemiological study of these 60 patients demonstrates that peripheral retinoschisis into bullous phase is only present under 5 years of age with tendency to regress with age (none reported after age of 50). This study corroborates ad absurdum the results of some authors who think that this type of retinoschisis has a tendency to improve spontaneously, and that indications for prophylactic and curative treatment must be thought of very carefully.
