Abstract

Purpose

To determine the changes in retinal thickness and whether they correlate with the size of the macular hole (MH) after vitrectomy with internal limiting membrane peeling.

Study design

Retrospective, interventional case series

Methods

Consecutive patients with an MH and undergoing pars plana vitrectomy with internal limiting membrane peeling were studied. The retinal thicknesses in the inner 4 sectors as defined by the Early Treatment of Diabetic Retinopathy Study were measured using spectral-domain optical coherence tomography (SD-OCT) before and at 2 weeks and 1, 3, 6, and 12 months after the surgery. The basal and minimum diameters of the MHs were measured. The correlations between the retinal thicknesses and the size of the MH were determined.

Results

Thirty-three eyes of 32 consecutive patients (18 women; mean age, 64.2 ± 8.8 years) with an MH were studied. Thirteen eyes had a stage-2 MH; 12 eyes, a stage-3 MH; and 8 eyes, a stage-4 MH. The mean retinal thickness in the temporal sector was 362.8 ± 29.9 µm preoperatively, 337.9 ± 20.6 µm at 2 weeks postoperatively, and 307.6 ± 20.2 µm at 12 months postoperatively (P < .001 for both, paired t tests). The respective mean thicknesses in the superior, inferior, and nasal sectors were 373.9 ± 34.9, 367 ± 28.7, and 385.5 ± 35.9 µm preoperatively; 361.6 ± 22.7, 359.4 ± 20.6, and 383.4 ± 29.0 µm at 2 weeks postoperatively (P = .0087, P = .049, P = .635); and 339.4 ± 18.9, 331.6 ± 21.4, and 371.3 ± 23.2 µm at 12 months postoperatively (P < .001, P < .001, P = .033). The changes in the retinal thickness at 2 weeks and 12 months in all 4 sectors were significantly correlated with the basal and minimum diameters of the MH.

Conclusions

Retinal thinning was observed soon after the MH surgery mainly in the temporal sector but also in the superior and inferior sectors. The thinning was greater in eyes with a larger MH, indicating that retinal structures dynamically change after internal limiting membrane peeling.
