Purpose:To evaluate Nd-YAG laser irradiation in the treatment of preretinal hemorrhage by creating an opening in the posterior vitreous membrane. Cases and Methods:We treated 7 eyes of 7 patients,including 5 eyes of retinal arterial maroaneurysm and 2 eyes of proliferative diabetic retinopathy. The interval from onset to treatment ranged 2 to 69 days,average 16.7 days. Results:The posterior vitreous membrane was perforated by Nd-YAG laser irradiation in all the eyes with adjunctive use of Peyman contact lens. Preretinal hemorrhage diffused through the opening into the vitreous cavity in all the eyes. Power output of laser ranged from 4.0 to 7.0 mJ,average 5.2 mJ. Visual acuity improved by 2 lines or more in 6 eyes. One eye needed additional vitrectomy. There was no funduscopically detectable complication. Conclusion:Hyaloidotomy by Nd-YAG laser may be effective for preretinal hemorrhage.
