Abstract
Purpose:
To investigate the merits of internal limiting membrane (ILM) peeling for regmatogenous retinal detachment (RRD) without foveal detachment preventing macular pucker formation.
Methods:
We conducted retrospective chart review on 41 patients who underwent primary pars plana vitrectomy (PPV) due to RRD without foveal detachment at Kyushu University Hospital between January 1, 2006 and June 30, 2010. Patients with a history of retinal surgery or another visually significant ocular condition were excluded. 19 patients underwent PPV with Brilliant Blue G (BBG)-assisted ILM peeling, and 22 patients without ILM peeling. We measured the occurring incidence of macular pucker at each group at least one year follow-up. Best-corrected visual acuity (BCVA), macular sensitivity (MS) on Humphrey Field Analyzer, and central foveal thickness (CFT) by optical coherence tomography (OCT) at post-operative 6 months were also measured.
Results:
BCVA, MS, and CFT were not statistically different at each group. The incidence of macular pucker formation was 0%(0/19) with ILM peeling, and 9.1%(2/22) without ILM peeling. The 2 patients with macular pucker have not undergone surgical procedure so far, because they have no metamorphopsia and good visual acuity.
Conclusions:
ILM peeling to prevent macular pucker formation for RRD without foveal detachment would not be useless from these data. However, it would be difficult to insist this merit strongly because ILM peeling performance has possible risk of retinal damage.
