Abstract
Background: Glaucoma is a complicated disease in which damage to the optic nerve leads to progressive, irreversible vision loss. Glaucoma is the second leading cause of blindness.
Aim of Study: The aim of this study is to determine the possible influence of the silicone oil tamponade after vitrec-tomy on the intraocular pressure which is a major risk factor for developing secondary glaucoma and the effect of starting with anti-glaucoma therapy during the first 6 months post-operative.
Patients and Methods: This prospective study was con-ducted from February 2018 to August 2018 and involved 35 patients (25 patients with retinal detachment, 10 patients with advanced proliferative diabetic retinopathy). All patients had vitrectomy with silicone oil tamponade. All patients signed an informed consent to participate in the study.
Results: Early elevation of IOP is equally present in the patients with RD as well as in those with PDR. However, a qualitative analysis of the two groups of patients showed higher IOP in patients with PDR. Silicone oil significantly affect visual acuity in both groups of patients causing deteri-oration of the visual acuity which affect PDR group more than RD group.
Conclusion: Silicone oil as a tamponade agent after pars plana vitrectomy may cause rise in the IOP values in the early post-operative period in some patients. Therefore the timely detection and appropriate antiglaucoma treatment is extremely important since every elevation of the IOP may interfere with the positive outcome of the surgical procedure and functional visual outcome.
