Anatomical and visual outcome of vitrectomy for giant retinal tear detachment with proliferative vitreoretinopathy: A retrospective, consecutive case series

Aim: To report the anatomical and visual outcome of giant retinal tear (GRT) associated detachment (RD) with advanced proliferative vitreoretinopathy (PVR) determine effect presenting clinical surgical variables Method: Retrospective, non-comparative, consecutive, interventional case series vitreoretinal surgeries performed in a private tertiary eye unit. Patient demographics, preoperative, intra-operative were assessed analyzed. Inclusion: Eyes which had surgery for previously unoperated GRT RD PVR > 3 months follow up. Exclusion: Other primary secondary forms no GRT. Results: Thirty-six eyes 36 patients evaluated. Male: female ratio = 5:1. Mean age 45.53 ± 13.2 years (range 12 - 65 years). Left eye, twenty-three (63.9%). Rate C D was 83%, four quadrant (total RD) 55.6%, macula 91.7%, size 90 to 180 degree 55.6% 33.3% respectively. Single attachment rate 41.7% final after second 86.1%. Visual CF or better Recurrent 58.3% due postoperative PVR. Gender, age, laterality, grade, size, quadrants affected by impact on (p> 0.05). Significantly, scleral buckle (SB) use did not reduce recurrent significant (p Conclusion: RDs have higher compared more commonly encountered RRD. When treating PVR, meticulous membrane removal should be accomplished using vital dyes aid visualization. This will recurrence Pre-, intra- post-operative factors, including SB affect single success. improvement is limited occurrence
