[Retinoschisis with a giant central outer layer retinal tear and concomitant detachment].

The authors report on 2 cases with a special form of senile retinoschisis with retinal detachment. In both cases, a typical retinoschisis was combined with a giant tear of the outer retinal layer and a sickle-shaped retinal detachment extending almost to the macula. In contrast to previously published cases, which were treated by a conventional scleral buckling procedure or vitrectomy with fluid air exchange, it was decided to demarcate the retinal detachment by argon laser photocoagulation. The authors consider this non-invasive procedure sufficiently safe and effective.
