Elevated Intraocular Pressure and Hypotony Following Silicone Oil Retinal Tamponade for Complex Retinal Detachment

Abstract

To evaluate the incidence of and risk factors for persistently elevated intraocular pressure (IOP) and hypotony in patients who have undergone pars plana vitrectomy with silicone oil injection for the management of complex retinal detachment. Subjects and Methods: The medical records of 532 patients who underwent silicone oil injection for the management of complex retinal detachments between January 1, 1991, and December 31, 1996, at the Bascom Palmer Eye Institute, Miami, Fla, were reviewed. Elevated IOP was defined as elevated IOP requiring an operation at any time postoperatively or a persistently elevated IOP of greater than 25 mm Hg at or after the 6-month visit. Hypotony was defined as a persistent IOP of 5 mm Hg or less at or after the 6-month visit. Patients with transient perioperative IOP fluctuations were not counted. Results: Survival analysis for patients without cytomegalovirus retinitis (n = 383) revealed that 12.9% had an elevated IOP and 14.1% had hypotony by 6 months, 21% had an elevated IOP and 20.3% had hypotony by 1 year, and 29.5% had an elevated IOP and 27.3% had hypotony by

Risk Factors for Redetachment and Worse Visual Outcome after Silicone Oil Removal in Eyes with Complicated Retinal Detachment

“…In our series we found hypotony in 6% of cases, which is comparable to earlier studies (5,11,13,26). Theories suggest that anterior PVR, traction, and detachment of the ciliary body may result in diminished aqueous humor production (4,(43)(44)(45). In an earlier smaller study we found a retinectomy size of 180 degrees or more to be a significant risk factor for hypotony (6).…”

Phrynoderma in a patient with megaloblastic anemia

“…This is comparable to previous studies that have reported 14.8–35.6% of the cases developing post-PPV early IOP rise. [10–12] As reported in a previous study,[13] this study also revealed that cases with an early rise in IOP are more likely to have a persistent elevation in IOP ( P = 0.02). This was evident by the fact that 5 out of 15 cases with an early rise in IOP developed a persistent rise in IOP requiring medical or surgical management.…”
