Purpose: To characterize the change in visual acuity (VA) in eyes treated with vitrectomy using the 2020 international consensus-based optical coherence tomography (OCT) definition of lamellar macular hole (LMH), macular pseudohole (MPH), and epiretinal membrane with foveoschisis (ERMF). Methods: A retrospective chart review was performed from 2000 to 2022 of patients who had vitrectomy for symptomatic decreased VA from LMH, MPH, or ERMF performed by the same surgeon at a community hospital. Preoperative spectral domain (SD-OCT) was reviewed to classify patients using the consensus guidelines. Primary outcomes were the mean change in best-corrected VA at 3 months, 1 year, and the final postoperative examination. Results: Fifty-one patients were included, 30 with LMH, 14 with MPH, and 7 with ERMF. The VA was 20/63 at baseline, 20/62 (P = .79) 3 months postoperatively, 20/40 (P = .003) at 1 year, and 20/52 (P = .10) at the final examination for LMH; 20/64, 20/50 (P = .16), 20/40 (P = .040), and 20/40 (P = .02), respectively, for MPH; and 20/53, 20/50 (P = .42), 20/30 (P = .03), and 20/38 (P = .04), respectively, for ERMF. Subgroup analysis showed that eyes with LMH without ellipsoid zone (EZ) disruption on SD-OCT improved from 20/57 at baseline to 20/39 (P = .01) at the final examination. Conclusions: There was no significant improvement in VA at the final postvitrectomy examination in eyes with LMH, while there was significant improvement in eyes with MPH and ERMF. This supports surgery in selected eyes with MPH and ERMF but possibly not in eyes with LMH, unless OCT shows no EZ disruption.

UNASSIGNED: This work compares best-corrected visual acuity (BCVA) and central retinal thickness (CRT) outcome measures following pars plana vitrectomy (PPV) with and without internal limiting membrane (ILM) peel for epiretinal membrane (ERM).
UNASSIGNED: A retrospective cohort study was conducted of 114 eyes of 114 patients with visually significant ERM undergoing PPV with membrane peel (PPV/MP) at a single institution. CRT measurements were collected from Heidelberg and Zeiss spectral-domain optical coherence tomography imaging units. Results compared preoperative and postoperative CRT and BCVA among patients with at least 60 days of follow-up.
UNASSIGNED: A total of 114 eyes with ERM met the inclusion criteria. Eighty-one eyes (71%) underwent PPV/MP with ILM peel and 33 eyes (29%) underwent PPV/MP without ILM peel. There was no statistically significant difference between preoperative CRT between the 2 study groups (P = .95). The mean follow-up time of eyes undergoing PPV/MP without ILM peel and with ILM peel was 391 days and 319 days, respectively. There was no statistical difference in the mean reduction of CRT between the 2 groups (P = .470). Both groups had improvement of BCVA following surgery and there was no statistical difference in final logMAR visual acuity when comparing the 2 groups (P = .738).
UNASSIGNED: There was an overall improvement of CRT and BCVA among patients undergoing PPV/MP for ERM with or without ILM peel. There was no statistically significant difference in the final BCVA or CRT between the 2 groups.

UNASSIGNED: To describe a case of an inflammatory macular hole associated with ocular syphilis and its successful surgical closure.
UNASSIGNED: A 55-year-old man presented with count fingers vision and was found to have unilateral ocular syphilis with panuveitis and a foveal subretinal lesion. The inflammation quickly resolved with treatment, but he developed a full-thickness macular hole on day 5. A pars plana vitrectomy with membrane peel and intraocular gas was performed three months later. The macular hole was successfully closed, and the patient\'s vision improved to 20/200 18 months after repair. Foveal outer retinal atrophy limited final vision improvement.
UNASSIGNED: Ocular syphilis can rarely be associated with inflammatory macular holes. Surgical intervention can offer successful anatomic results; however, final visual outcomes may be limited by retinal scarring or atrophy from the original inflammation.

OBJECTIVE: Macular pucker (MP) and macular hole (MH) are vitreomaculopathies treated by vitrectomy and membrane peel. The complication of postoperative central scotoma can be associated with significant reduction in visual acuity (VA). We seek to determine whether retinal nerve fiber layer (RNFL) disruption is the pathophysiologic basis of this defect. Mitigating clinical circumstances also were sought.
METHODS: Eleven eyes from 10 pseudophakic patients who had undergone vitrectomy with peeling for either MH or MP were studied with clinical measures, including optical coherence tomography (OCT). Membrane specimens were evaluated by immunohistochemistry for neurofilament, a marker for the inner retina. Ten eyes from 10 pseudophakic patients who underwent repeat surgery for persistent or recurrent pathology were evaluated to determine the relationship between the timing of reoperation and clinical outcome.
RESULTS: Cases with a postoperative central scotoma (N=4) had worse VA (~20/600) compared to those without (N=7, ~20/30, P=0.01). Eyes with a central scotoma had significantly reduced RNFL thickness in the temporal quadrant (53.67 vs. 72.33 μm, P=0.05) by OCT. A central scotoma was associated with more disruption of the inner retina on immunohistochemistry (P=0.03). In patients with persistent or recurrent pathology, waiting six months before reoperation resulted in better functional outcomes (P=0.03).
CONCLUSIONS: Central scotomata and poor VA were associated with disruption of the RNFL during membrane peeling. Affected patients have RNFL thinning and signs of optic neuropathy, for which we propose the term inner retinal optic neuropathy (IRON). In patients requiring reoperation, waiting six months between surgeries may reduce the risk of IRON.
