Purpose: Intravitreal silicone oil (SO) is used as a tamponade in the management of complicated retinal detachments. One of known complications of SO is the development of secondary glaucoma. We have investigated the character of the glaucoma after pars plana vitrectomy with SO for complicated retinal detachments.
Materials and Methods: Medical records of 220 eyes of 215 patients who underwent pars plana vitrectomy combined with SO for the management of complicated retinal detachment between January 2000 and April 2016 at Fukuoka University Hospital were reviewed. Secondary glaucoma after pars plana vitrectomy was observed in 27 eyes of 26 patients(12.2%). The study included 15 men and 12 women. The average age was 50.6±15.3 years old. Retinal detachment was due to proliferative vitreouretinopathy in 18 eyes, macular hole retinal detachment in 6 eyes, rhegmatogenous retinal detachment in 3 eyes. Patients with a history of glaucoma, acute-onset IOP elevation cases within 7 days of SO injection were excluded. Elevated IOP was defined as a persistently elevated IOP greater than 21 mmHg.
Results: The average IOP was 10.7±4.5 mmHg before the injection of SO, and 24.6± 4.1 mmHg after injection. SO was removed in 21 eyes and was not removed in 6 eyes. The timing of IOP elevation ranged from 1 to 24 months after SO injection and the average was 6 month. IOP resulted in normal pressure in 12/21 eyes(57%) after SO removal. Nine eyes resulted with elevated IOP even after the SO removal. Anti-glaucoma eye drops were used in 9 eyes and trabeculectomy was needed for the 2 eyes with uncontrolled elevated IOP.
Conclusions: SO tamponade induced the elevation of IOP in 12%. Secondary glaucoma after SO injection occurs at average of 6 month after SO injection. IOP was normalized after removal of SO in 57% of the cases. Anti-glaucoma eye drops and glaucoma surgery were necessary in 43% cases.
