  • Retrohyaloid Preretinal Hemorrhage

    A 44-year-old man with a history of proliferative diabetic retinopathy previously treated with panretinal photocoagulation presented with a sudden decrease in visual acuity in his left eye. On examination, best-corrected visual acuity was reduced to counting fingers, and intraocular pressure was 16 mmHg in the left eye. Slit-lamp examination of the anterior segment was unremarkable. Fundus examination showed a retro-hyaloidal hemorrhage masking the macula (Figure, top left). As no spontaneous improvement was observed after one week of follow-up, Nd:YAG laser hyaloidotomy was performed. Three laser shots of 7 mJ were applied on the lower part of the blood collection (Figure, middle, immediately after laser treatment). The hemorrhage was successfully released into the vitreous cavity (Figure, top right), with subsequent improvement in visual acuity to 20/40.
