Macular Evaluation by Optical Coherence Tomography after Pars Plana Vitrectomy with Silicone Oil Tamponade in Cases of Primary Rhegmatogenous Retinal Detachment

Background: Rhegmatogenous retinal detachment (RRD) is a disorder that can cause blindness in the eyes. RRD is present in 6.3 to 17.9 persons per 100,000, with individuals between 60 and 69 having the highest frequency. Objectives: To evaluate the macular changes by OCT after pars plana vitrectomy (PPV) with silicone oil injection in cases of primary RRD. Subjects and methods: This prospective interventional study included (40) eyes with recent RRD and was done at Al-Azhar University Hospitals. Result: There was a significant difference between two weeks after vitrectomy and 3 months after (P1= 0.01). There was a substantial difference between 2 weeks after vitrectomy and 6 months after (P2= 0.014). There was a significant difference between 2 weeks after vitrectomy and 6 months after vitrectomy at BCVA score 1.7, (P2= 0.03), 2 weeks after vitrectomy, and 3 months after vitrectomy at score 1.5, (P1= 0.03). Between 2 weeks after and 6 months after vitrectomy, the BCVA score was 1.3 (P2= 0.04). Conclusion: For the treatment of primary RRD, PPV combined with SO injection is a safe and effective surgical technique. More extensive multicenter clinical studies are yet required to corroborate and confirm our results completely.
