a Full-thickness, stage IV macular hole. Inner diameter is 400 microm. Outer diameter is 1,617 microm. Vitreofoveal traction is visible. Visual acuity is 0.04. b Full-thickness macular hole after the first surgery. Remnants of the inverted ILM flap are visible on the retinal surface. They do not cover the macular hole. c One week after vitrectomy with silicone oil. The macular hole is closed, but the fovea contour is irregular and a cystoid space in the outer retina is visible. d One week after silicone oil removal. The line representing the junction between inner and outer segments of photoreceptors tends to normalize. Outer photoreceptor segments seem elongated. e Fovea appearance 18 months after surgery. Fovea contour is almost normal. Remnants of the ILM are still visible on retinal surface. The line representing the junction between inner and outer segments of photoreceptors seems intact in the fovea. Visual acuity is 0.4.

The upper diameter of the macular hole was 400 microm, the lower diameter 1,617 microm, and posterior hyaloid traction was visible (fig. 1a). The macular hole did not close either 1 week or 1 month after surgery (fig. 1b), and the patient qualified for repeat surgery with silicone oil. The macular hole was closed 1 week after surgery (fig. 1c). Visual acuity was 0.15 six months after surgery (fig. 1d) and then gradually improved to 0.4 eighteen months after surgery (fig. 1e).
