Purpose:
To report a case of ocular decompression retinopathy after bleb needling in a patient with extremely high intraocular pressure.
Methods:
Case report of a 55-year-old man who had undergone trabeculectomy for neovascular glaucoma and bleb needling to lower intraocular pressure.
Results:
During the procedure, the anterior chamber collapsed suddenly as a result of overdrainage, and the intraocular pressure decreased rapidly from 60 mmHg to 2 mmHg. Funduscopy performed the next day showed multiple intraretinal hemorrhages in all quadrants. Fluorescein angiography showed no evidence of occluded retinal vessels. He had no history of any bleeding disorder. Decompression retinopathy was diagnosed.
Conclusion:
Decompression retinopathy can occur after bleb needling, which is often required after trabeculectomy to restore bleb function.
