Aim: To investigate the relationship between the size of macular holes and the possible benefit of internal limiting membrane (ILM) peeling.
Methods: 84 consecutive cases of idiopathic macular hole followed up for at least 3 months were included in this retrospective study. Surgery comprised pars plana vitrectomy, peeling of any epiretinal membrane, 17% C2F6 (hexafluoroethane) gas filling and 10 days of positioning. 36 eyes had ILM peeling. The main outcome measure was the macular hole closure rate checked by optical coherence tomography.
Results: The overall postoperative closure rate was 90.5%. For macular holes > or =400 microm in diameter, the rate was 100% with ILM peeling versus 73.3% without (p = 0.015). For smaller macular holes, the rates were 100% in both groups. Postoperative gain in visual acuity was not significantly different in eyes with ILM peeling and those without.
Conclusions: ILM peeling does not seem to be useful for macular hole <400 mum in diameter. Its likely benefit has to be investigated for larger macular hole sizes, for which the failure rate is higher.

Drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment in highly myopic eyes.

Purpose: The purpose is to evaluate the effect of drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment (MHRD) in highly myopic eyes.
Methods: This study is a retrospective, observational, and comparative case series that included 25 consecutive highly myopic eyes with MHRD. All eyes underwent standard 23-gauge vitrectomy, inverted internal limiting membrane insertion into the macular hole, subretinal fluid drainage from an intentionally created extramacular retinal hole, and tamponade with either silicone oil (SO group, n = 13) or perfluoropropane (CF group, n = 12).

To assess retinal pigment epithelium (RPE) tears in eyes which underwent pars plana vitrectomy (PPV) for submacular hemorrhage (SMH) secondary to age-related macular degeneration and to investigate the prognostic factors of visual outcomes. This study was a retrospective, observational case series that included 24 eyes of 24 patients who underwent PPV with subretinal tissue plasminogen activator and air for SMH. RPE tears were investigated using spectral-domain or swept-source optical coherence tomography images with raster scan, combined confocal scanning laser ophthalmoscope near-infrared images and color fundus photographs.

Purpose: Human amniotic membrane (hAM) grafts have been used to close persistent macular holes in recent years. The results from these surgeries are promising with improved closure rate and vision. However, there is lack of data for what happens to these membranes and how long the tissue should remain inside the patient's eyes.

A septuagenarian man presented with a visual acuity of hand motions and a large refractory macular hole (MH). We performed an autologous retinal transplant (ART) and covered the graft with fibrin glue without any endotamponade. The autograft was found to have dislocated from the MH when the patient was reviewed 1 week later.
