Abstract. Purpose:To report a case of diabetic retinopathy that developed retinal detachment during vitreous surgery 2 months after pattern scan laser photocoagulation. Case:A 64-year-old female was referred to us for diabetes mellitus. She had been diagnosed with diabetes at the age of 35 years but received no treatment. Findings:Corrected visual acuity was 0.9 right and 0.5 left. Both eyes showed proliferative diabetic retinopathy and received pattern scan laser photocoagulation. The laser was set in yellow range, power output was set from 500 to 800 mW, size of laser spot was 200μm, and each laser was applied for 200 to 300 milliseconds. The left eye underwent simultaneous cataract and vitreous surgery 2 months later. During resection of peripheral vitreous, a presumably iatrogenic retinal tear was detected followed by retinal detachment extending over the site of previous laser photocoagulation. The retina reattached following fluid-air exchange and coagulation of the area around the tear. There has been no recurrence for 2 years. Conclusion:This case illustrates that pattern laser photocoagulation at the above setting may not induce firm retinochoroidal adhesion.
