Infantile angle closure glaucoma (ACG) is a rare consequence of retinopathy of prematurity (ROP) and usually occurs a few years after laser treatment for ROP.1–3 A Medline search for ACG following laser photocoagulation extracted only one case. In the case, ACG occurred in 2 weeks after laser photocoagulation and although occurrence of iris bombe in both eyes was described, the mechanism for the ACG was not fully clarified.4

We present a case of bilateral ACG that occurred within a several weeks after the laser photocoagulation for ROP. We shall discuss the importance of ultrasound biomicroscopy (UBM) in the diagnosis.

Case report

A baby girl, born at 25 weeks gestation weighing 796 g, was diagnosed with stage 2 plus, zone 2 ROP bilaterally at 33 weeks. Diode laser photocoagulation, 986 applications right eye and 629 left eye, with 200–240 mW, 0.4 second duration, was performed by a paediatric ophthalmologist. On the following day, severe hyphaema was observed …
