A modified laser test for the identification of retinoschisis.

Abstract

To describe a modified laser technique for identification of bullous retinoschisis. Retrospective interventional case series collected over 10 years. Forty-one eyes with presumed bullous retinoschisis and breaks in the inner layers underwent a low-energy argon green laser application at the same energy as a control spot in adjacent retina. A gray response in the outer layers equal to the control spot was diagnostic of retinoschisis. The laser test was positive for retinoschisis in 40 of 41 eyes. In none of the 40 eyes did the elevation progress. A low-energy argon green laser application through a break in the inner layers of presumed retinoschisis eliminates the attenuation of the beam and can confirm retinoschisis.
