Pupillary block glaucoma in phakic eyes using 5000 centistoke silicone oil.
OBJECTIVE
To describe pupillary block glaucoma in phakic patients undergoing vitrectomy and 5000 centistoke silicone oil injection.


METHODS
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.


CONCLUSIONS
Vitreoretinal surgeons should be aware of silicone-induced pupillary block glaucoma in phakic eyes, even when higher-viscosity silicone oils are used.
