Static and kinetic perimetry results of krypton red laser treatment for macular edema complicating branch vein occlusion.
Twenty patients with clinical and angiographic evidence of recent branch vein occlusion complicated by macular edema were assigned to receive krypton red laser treatment if their macular edema lasted more than three months. Visual acuity, static and kinetic perimetry, fundus photography, and fluorescein angiography were evaluated before treatment and at two-month intervals thereafter. Visual acuity improved by two lines one year after treatment in 65% of patients. Each of these patients had a complete perifoveal capillary arcade. Static perimetry results correlated well with visual acuity, and a significant threshold improvement was detected in these patients. Visual-acuity results and static and kinetic perimetry findings are presented. The rationale for selection of the krypton red wavelength (647 nm) is discussed.
