Objective: To report the case of a patient with severe non-proliferative diabetic retinopathy who developed angle closure after undergoing retinal photocoagulation (PRP) with a yellow Pascal 577 nm laser.

Observation: 30-year-old male with severe non-proliferative diabetic retinopathy presented with severe ocular pain and nausea one day after undergoing laser photocoagulation in the left eye for the treatment of his diabetic retinopathy. His visual acuity was 20/200 and his intraocular pressure (IOP) was 45 in his left eye. It had a shallow anterior chamber that was closed on gonioscopy. Ultrasonic biomicroscopy (UBM) reported an anterior chamber of 1.68 mm with narrow iridocorneal angles. He was managed with medications to reduce IOP, which included cycloplegics, topical and oral steroids. He was closely followed with serial examination and the intraocular pressure was reduced before developing glaucoma.

Conclusion: Patients presenting with ocular pain and increased IOP after laser photocoagulation should increase suspicion for angle closure. Limiting the number of laser burns and the amount of retinal area treated can prevent this problem from occurring.
