Abstract
Purpose:To describe pupillary block glaucoma in phakic patients undergoing vitrectomy and 5000 centistoke silicone oil injection.
Design:Observational case reports.
Methods:Vitrectomy and higher-viscosity silicone oil injection was performed in two phakic patients with proliferative diabetic retinopathy.
Results:Both patients developed a pupillary block in the early postoperative period (1 week and 1 month after surgery). Unnoticed zonulysis during surgery, thought to be the main contributory cause, allowed access of the silicone oil between the iris and the lens. Although higher-viscosity silicone oil was used in both cases, an acute glaucoma developed. An inferior iridotomy was performed, resulting in a temporary resolution of the pupillary block.
Conclusion:Vitreoretinal surgeons should be aware of silicone-induced pupillary block glaucoma in phakic eyes, even when higher-viscosity silicone oils are used.
