Abstract

Purpose : To compare the retinal thickness in the parafoveal regions and fovea migration of eyes after successful closure of a macular hole (MH) by vitrectomy with air tamponade and conventional internal limiting membrane (ILM) peeling or hemi-temporal ILM peeling (peeling only temporal side of MH).

Methods : The medical records of patients with an MH that had undergone vitrectomy with ILM peeling and air tamponade in St. Marianna University School of Medicine Hospital were studied. 39 eyes with successful closure of MH were divided into 2 groups based on surgical procedure [hemi-temporal ILM peeling (Hemi-group): 14 eyes, conventional 360-degrees ILM peeling (360° group): 25 eyes]. The parafovea retinal thickness of temporal or nasal side were measured manually with optical coherence tomographic (OCT) at baseline, 1week and 1 month postoperatively. The preoperative distances between the center of the MH and the optic disc (MH-OD) and postoperative distance between the center of the fovea and optic disc (F-OD) were measured in the Near-infrared images. We defined (MH-OD)-(F-OD) as fovea migration length.

Results : The fovea migration length to optic disc at 1 week and 1 month after surgery were 117.6±102.7, 150.3±90.1 μm in 360° group, and 67.8±115.0, 113.9±104.1 μm in Hemi-group. In Hemi-group, fovea migration length is significantly shorter than that of 360° group (p<0.001). The mean temporal parafovea thickness were 348.9±28.2 μm at baseline, 325±22.1 at 1week, 325±22 μm at 1month in 360° group, and 340.5±23.6, 321.4±20.9, 316±21.2 μm in Hemi-group, respectively. In both groups, the temporal parafovea thickness were significantly decreased at each time point (p<0.05, respectively). And there are no differences between two groups. The mean nasal parafovea thickness were 370.8±53.5 at baseline, 365±25.6 at 1 week, and significantly increased to 385.9±22.5 μm at 1 month in 360° group (p< 0.05 at 1month). In Hemi-group, the mean nasal parafovea thickness were 364.2±38.6 at basline, 347.9±19.9 at 1 week and 363.9±25.6μm at 1 month. Significant changes were not observed in Hemi-group.

Conclusions : Hemi-temporal ILM peeling brought less displacement of fovea which might have a possibility of advantage to hole closure.
