The authors discuss the typical signs and symptoms of congenital retinoschisis: splitting of the retinal layers in the macular and equatorial regions and vitreous changes. They describe the evolution of these changes and their complications.
The authors call attention to the existence of incomplete forms of retinoschisis and some forms with predominant macular changes which may erroneously be treated as Stargard's disease. A correct diagnosis is essential because of the necessity of a systematic control of the fundus periphery. Discussed are the possibilities of prevention and treatment of complications such as haemorrhages and retinal detachment.

Twenty four patients with a preoperative macular detachment were subjected to a 6 months observation. The evaluation of the macular function was carried out on the basis of following examinations: the visual acuity, central visual field, dazzling test, Amsler's test and Heidinger phenomenon. The morphology of the changes was evaluated ophthalmoscopically and biomicroscopically by means of Goldmann's lens and the slit-lamp. The macular pucker appeared in 25 p.c. of examined patients, in 16.7 p.c. of cases with non-translucent and in 8.7 p.c. with translucent membranes. In all cases of macular pucker after retinal detachment surgery the macular function remained severely handicapped.
