A modified laser test for the identification of retinoschisis.

Overview

PURPOSE: To describe a modified laser technique for identification of bullous retinoschisis. DESIGN: Retrospective interventional case series collected over 10 years. METHODS: 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. RESULTS: The laser test was positive for retinoschisis in 40 of 41 eyes. In none of the 40 eyes did the elevation progress. CONCLUSIONS: 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.
