(A) Ophthalmoscopy revealed a horseshoe-like tear on the temporal side of the macula in the left eye. (B) Fluorescein angiography revealed a non-perfusion area and that there was no retinal vein occlusion. (C) Spectral-domain optical coherence tomography revealed the focal retinal detachment in the left eye reached the fovea.

Ophthalmoscopy revealed a horseshoe-like tear on the temporal side of the macula in the left eye (Figure 1A). Fluorescein angiography (VX-10i; Kowa Co., Ltd., Nagoya, Japan) revealed a nonperfusion area and the absence of any findings of retinal vein occlusion (Figure 1B). Spectral-domain optical coherence tomography (Cirrus HD-OCT, Carl Zeiss Meditec AG, Jena, Germany) using the HD 5-line raster scan protocol (horizontal scan of 6 mm) revealed a focal retinal detachment that reached the fovea in the left eye (Figure 1C).
(A) A few days after the first visit, there was no longer adhesion of the flap of the tear to the retina and the tear size had increased to 1.5 disc diameters. (B) Before the surgery, the macular tear size was 1.5 disc diameters. (C) In order to close the tear, we performed the inverted internal limiting membrane flap technique with 20% SF6 gas tamponade. (D) Although the disc diameter of the tear after the surgery decreased to 0.5 disc diameters, complete closure of the tear was not achieved.

A few days after the first visit there was no longer adhesion of the flap of the tear to the retina and the tear size had increased to 1.5 disc diameter (Figure 2A). The patient provided written informed consent to be part of this case study. To close the tear, we performed the inverted internal limiting membrane flap technique with 20% SF6 gas tamponade (Figure 2B and C). Although the tear decreased to 0.5 disc diameter after the surgery, it did not achieve complete closure (Figure 2D).
