Purpose: We describe the occurrence of a massive retinal hemorrhage following anterior chamber paracentesis in uveitic glaucoma. Methods: A 33-year-old man who suffered from uveitic glaucoma was transferred to our hospital. The IOP in both his eyes was documented to vary between 11 mmHg and 43 mmHg and remained at a continuously high level for 7 months despite maximally tolerable medical treatment. A paracentesis was performed bilaterally to lower the IOP. Results: Immediately after the paracentesis, massive retinal hemorrhages occurred in the left eye. Multiple round blot retinal hemorrhages with white centers occurred in the equator and peripheral retina, and small slit hemorrhages were observed in the peripapillary area. A fluorescence angiography(FAG) showed no obstruction of retinal vessels but a slightly delayed arteriovenous time in the left eye. Conclusions: It is important to be aware that patients who have a persistent relatively high IOP are at an increased risk of developing decompression retinopathy due to paracentesis and filtering surgery.
