Abstract

Purpose : To investigate retinal sensitivity changes in the central 10 degrees after vitrectomy for epiretinal membrane (ERM) or macular hole (MH) in patients with glaucoma.

Methods : Seventy-one eyes of 71 patients who underwent vitrectomy with internal limiting membrane (ILM) peeling for ERM or MH were included: glaucoma patients (G group), 29 eyes; non-glaucoma control group (C group), 42 eyes. The main outcome measure was postoperative visual field (VF) changes (5.3 ± 4.3 months after surgery) in standard automated perimetry (Humphrey visual field analyzer II, SITA standard 10-2 program). For each test point, ≥5 dB decrease in total deviation postoperatively was defined as deterioration in G group. For C group, test points with probability <1% on a pattern deviation map of postoperative VF were deemed as deterioration. We also evaluated best-corrected visual acuity (BCVA) and ganglion cell complex (GCC) thickness in the central 10 degrees by optical coherence tomography (RS-3000, NIDEK). VF and GCC thickness were analyzed in each sector; center, inner ring, and outer ring, defined by three concentric circles, 3.3°-, 10°- and 20°-diameters. Preoperative and postoperative factors related to the mean deviation (MD) changes were identified using univariate and multivariate linear regression analysis.

Results : Postoperative MD was -9.4±6.7 dB in G group, and -1.1±1.1 dB in C group. Postoperative pattern standard deviation (PSD) was 8.7±5.0 dB in G group, and 1.4±0.6 dB in C group. In G group, postoperative MD and PSD were significantly deteriorated after surgery (P<0.01). The number of deteriorated test points was 12.2±8.3 in G group and 1.4±2.2 in C group. Fourteen out of 68 test points were deteriorated in >30% of 29 eyes in G group and were located in the nasal half of outer ring. In both groups, GCC thickness was significantly decreased after surgery (P<0.01), and its postoperative value of G group was significantly thinner than C group (P<0.01). BCVA was significantly improved after surgery in both groups (P<0.01). In G group, a multivariate regression analysis identified preoperative PSD as the associated factor for MD changes (β=-0.396, P=0.03).

Conclusions : In glaucomatous eyes with ERM or MH, retinal sensitivity in central 10 degrees, especially in the nasal half of outer ring, may deteriorate after vitrectomy with ILM peeling.
