SEX‐LINKED HEREDITARY JUVENILE RETINOSCHISIS

R. Tarnquist (Urebro): In many cases the defect of the visual field in retinoschisis is considered to correspond exactly to the degree of the eyeground changes. However, not infrequently “islands” of maintained perception are found in the defect, which may be explained by the rather common perpendicular connexions between the two layers of the retinoschisis. Generally, the condition is stationary, but occasionally it may progress, and this can be observed most easily by the changes in the visual field. Only in such cases, the condition should be treated with photocoagulation, since this therapy is not without risks. Hence, an extensive rupture of the retina along the edge of the retinoschisis may occur, resulting in detachment of the retina.
