Visual loss following removal of silicone oil has been reported in several studies, although its etiology remains unclear. The authors performed a retrospective, observational clinical study to determine the relationship between the use of silicone oil (SO) as an intraocular tamponade and the incidence of unexplained loss of visual acuity.
The study involved 175 patients, who underwent SO removal at the Department of vitreo-retinal surgery at Centro Hospitalar São João between January 2012 and June 2015. Patients who had reduction of vision of unexplained cause after SO extractions were studied, searching for possible retinal toxicity of intraocular silicone
Nine patients (5.1%) (4 male, 5 female), with a median age of 57 years (range 31–84 years) reported reduction of vision of unexplained cause after SO extractions. The median time of SO fill was 8 months (range 4–21 months). Patients with 2 or more lines of vision loss of unexplained cause after removal of silicone oil showed a mean drop of visual acuity of 0.2. The intraocular pressure (IOP) became elevated in 7 (77.8%) eyes during the follow up period. Only 2.9% of patients who underwent removal of silicone oil had cataract as a complication
There is a 5.1% overall incidence of unexplained loss of vision in eyes following SO removal, with a high rate in women (55.6%). The main complication observed was ocular hypertension.
