A 60-year-old female presented with decreased vision in right eye for 3 months. Her best-corrected visual acuity in right eye was 20/200 and 20/20 in left eye. Both her eyes were pseudophakic. Posterior segment examination of right eye showed two vertically oriented full-thickness macular holes (FTMH) with a bridging retinal tissue in between them. The superior hole was larger in size and temporal in location compared to the inferior one. The combined vertical base diameter, assuming both to be a single macular hole, was 1997 μm [Figure 1].

Optical coherence tomography (OCT) showed persistent vitreomacular adherence causing significant traction and two vertically oriented FTMH separated by a bridging strip of retinal tissue [Figure 2]. Microperimetry showed poor sensitivity in the region of the two holes, but moderate sensitivity in the area of bridging strip of retinal tissue between the two holes [Figure 3].

The patient underwent conventional macular hole surgery, i.e., 25G pars plana vitrectomy, posterior vitreous detachment induction, internal limiting membrane peeling around the holes, and gas tamponade. Following surgery, type-1 closure was achieved [Figure 4]. However, there was no improvement in vision.

| Discussion|| |
Apparent double macular hole is a rare entity, with only one de novo case reported previously, i.e., by Cheng et al. in 2000. They reported a female who had two holes, which later coalesced into a single large MH after a period of 10 weeks. Peiretti et al. reported a case of “apparent” double macular hole, where one partial-thickness MH along with one FTMH gave the appearance double macular hole. Li et al. and Khuranareported one case each, where double macular hole developed after vitrectomy for vitreomacular traction (VMT) syndrome and rhegmatogenous retinal detachment, respectively.,
Cheng et al. hypothesized that the apparent double macular hole can develop due to uneven traction at the various points of focal attachments in the region of foveal and perifoveal region. The OCT images in our case show such a vitreomacular adherence causing significant traction, resulting in two macular holes.
We report a rare case of apparent double FTMH caused by VMT. We also report the microperimetry in such a case, which has not been documented earlier to the best of our knowledge.
