“…Reviewing the preoperative data and surgical techniques (Table 1), the time to initial surgery seemed to be different between the two groups with a range of 10 days to 2 months in the good final BCVA cases and a range of 4–5 months in the poor final BCVA cases. Both the case reported by Gao and associates7 and this case showed severe thinning and loss of the entire outer photoreceptor bands including the ellipsoid and external limiting membrane and retinal pigment epithelial layer. These OCT findings may explain the poor postoperative BCVA in these cases.…”

“…Including our patient, all seven eyes achieved anatomical closure of the FTMH, although one case required repeat vitrectomy combined with internal limiting membrane peeling 5. Some authors have reported excellent visual acuity,23456 while others, including our case, achieved hole closure with a modest improvement in visual acuity 7. Reviewing the preoperative data and surgical techniques (Table 1), the time to initial surgery seemed to be different between the two groups with a range of 10 days to 2 months in the good final BCVA cases and a range of 4–5 months in the poor final BCVA cases.…”

“…Late complications include chorioretinal scarring and neovascularization, macular cyst, macular pucker, and FTMH 1. Some FTMHs may close spontaneously,8 but most cases require surgical repair 234567. The pathophysiologic mechanism of a laser-induced FTMH differs from an idiopathic FTMH, which is related to the tractional forces created by an anomalous posterior vitreous detachment 48.…”

“…Q-switched Nd:YAG laser is particularly harmful as it is designed to emit short pulses of high energy in durations of few to tens of nanoseconds and can deliver an invisible dose of energy very rapidly to the retina 1. Nd:YAG laser-induced macular hole injury has been previously reported,2345678 but there are few previous case reports that have noted successful repair and recovery of vision following pars plana vitrectomy 234567. Herein, we report a case of 21-year-old female who developed a large, full-thickness macular hole (FTMH) after inadvertent Nd:YAG laser exposure and who underwent successful surgical closure of the hole but did not regain full visual acuity.…”

The Q-switched Nd:YAG laser can cause significant ocular injury, because it can emit an invisible and powerful load of energy in a short period of time. One of these injuries is macular hole formation. We report the case of a 21-year-old woman who presented with acute floaters in her left eye after exposure to a Q-switched Nd:YAG laser. Her initial best-corrected visual acuity (BCVA) in the left eye was 20/80. Examination demonstrated an acute vitreous hemorrhage, and spectral-domain optical coherence tomography (SD-OCT) confirmed a full-thickness macular hole (FTMH). Four months after her injury, her BCVA deteriorated to 20/400, and she underwent vitrectomy, internal limiting membrane peeling, and gas injection. Three weeks following the procedure, her FTMH was closed, however, her BCVA remained 20/150. At her last office visit, 19 months after the surgery, the examination was unchanged. There are few reports of vitrectomy to close an FTMH after Nd:YAG laser exposure, and the factors that contribute to visual recovery remain unclear. The aim of this case report is to emphasize the importance of early diagnosis and surgical repair, and to review the literature and surgical outcomes of cases of Nd:YAG laser-induced macular holes. Imaging with SD-OCT was essential in evaluating the visual outcome, as it was dependent on the degree of photoreceptor and retinal pigment epithelium injury.

“…The Q-switched Nd:YAG laser may cause photodisruption at the injury site, which occasionally results in a macular hole [1,2,3,4,5,6,7]. Thach et al [1] described 5 eyes of 4 patients with macular holes caused by accidental Q-switched Nd:YAG laser injury.…”

A 31-year-old man sustained a 1,064-nm Q-switched Nd:YAG laser injury to his left eye. One month after the injury, the fundus and optical coherence tomography (OCT) examination demonstrated a full-thickness macular hole of approximately 820 µm in diameter. After vitrectomy and internal limiting membrane peeling, OCT showed closure of the hole and a marked thinning of the foveal depression. After 12 months of follow-up, his visual acuity improved from 20/60 to 20/20. The MP1-microperimeter demonstrated increased retinal sensitivity in the area of the previous macular hole and its adjacent region and improvement of fixation from a relatively unstable status to a stable status. The macular hole remained closed 24 months postoperatively with the best corrected visual acuity 20/20. Our results suggest that vitrectomy can improve the visual function when a macular hole is caused by Nd:YAG laser injury. The improvement in the visual function includes not only visual acuity but also retinal sensitivity and fixation stability that are obtained by using the MP1-microperimeter.
