Surgery of secondary glaucoma in patients with operated retinal detachment induced by emulsified silicone oil

Abstract

Purpose. To evaluate the efficacy of silicone oil induced secondary glaucoma surgery using shunt-drains.Material and methods. The study included 10 patients (10 eyes) aged 38-73 years. All patients had been previously operated for rhegmatogenous retinal detachment with vitreous cavity tamponade by silicone oil. The tamponade duration ranged from 1 year or more. All patients underwent the surgery for the secondary glaucoma induced by emulsified silicone oil. Either leucosapphire explantodrains or polymer micro-shunts were implanted in these patients. The follow-up period was 6 months.Results. There were no any intra-operative complications. Ciliochoroidal detachment occurred in 5 cases, hyphema – in 2 cases. Intraocular pressure after surgery was 20mmHg within a month. Subsequently, antihypertensive drugs were prescribed for 1 patient, and another 1 patient underwent transscleral cyclophotocoagulation. Expansion of visual field limits was 7-15°, improvement of visual functions was from hundredths to tenths.Conclusion. Glaucoma in eyes with previously operated retinal detachment, and complicated by the alteration of anterior chamber angle under the influence of emulsified silicone oil, requires a more radical approach to a surgical treatment with application of drains.The leucosapphire explantodrain and polymer micro-shunt show a sufficiently high hypotensive efficiency in relatively the same surgical technique.
