A modified laser test for the identification of retinoschisis.

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.
