Severe visual loss in patients with Behcet's disease after YAG laser posterior capsulotomy

We report on 2 patients with Behcet's disease who developed severe visual loss after yttriumaluminum-garnet (YAG) laser posterior capsulotomy. The first patient, a 51-year-old male who had undergone lens extraction when he was 42 years old, underwent YAG laser treatment for aftercataract. After the YAG laser treatment, he developed neovascular glaucoma and visual acuity decreased to no light perception. The second patient, a 34-year-old male, also underwent YAG laser capsulotomy after lens extraction. His laser surgery was performed 3 year after cataract surgery and was followed by secondary glaucoma and decrease in visual acuity to no light perception. These cases suggest that careful management is required for patients with Behcet's disease treated by YAG laser capsulotomy.
