To correlate the visual acuity (VA) outcome in eyes with the diagnosis of macular pucker after epiretinal membrane peel surgery with findings on Heidelberg Spectral Domain Optical Coherence Tomography (OCT)
This study was a retrospective analysis of 30 patients who underwent pars plana vitrectomy and epiretinal membrane peel for macular pucker between January 2009 and November 2009. A pre and post operative OCT was done at 3 months follow-up. The surgery was performed with a 23 gauge vitrectomy system and membrane peel was assisted with Indocianine Green stain.
Of the 30 patients 12 were female (40%) and 18 male (60%) with an average age of 70 years. 6 patients were diabetic. Visual acuity improved in 16 patients (54%), remained stable in 7 (23%), and worsened in 7 (23%). 11 (69%) of the 16 patients who improved VA gained more than 2 lines, and central macular thickness (CMT) improved by >10% in 10 (63%) of these. 6 (86%) of the 7 patients that decreased vision dropped 2 or more lines of VA, even though all of those (100%) improved CMT by >10%. Of these, 3 showed a disruption in the RPE-photoreceptor layers in the foveal or perifoveal area, 2 had intraretinal cysts (findings that were persistent through the pre and post-operative follow-up); and 2 patients developed cataracts secondary to gas used in surgery. In all, preoperative CMT was of 428 µm and 347µm postoperative (19% improvement).
Epiretinal membrane peel surgery proved to be beneficial in reducing CMT to a great degree. Although most patients improved vision significantly, the drop of VA in others is attributed to changes in the RPE-photoreceptor layer, intraretinal cysts (easily observable in the preoperative stages on Spectral Domain OCT), or development of postoperative cataracts.
