Purpose. To examine the relationship between the morphological and functional results in eyes after pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling due to stage 4 full-thickness macular hole (FTMH). Methods. The study included 22 eyes that underwent successful PPV due to FTMH. Both vertical metamorphopsia (VM) and horizontal metamorphopsia (HM) were determined using type 2 M-charts, as well as best-corrected visual acuity (BCVA), microperimetry, and optical coherence tomography (OCT) were performed before PPV and 1 and 6 months postoperatively. Results. A significant improvement of BCVA and metamorphopsia scores measured by M-charts in particular periods before surgery, 1 and 6 months after PPV, was observed. The VM scores were consistently higher than the HM scores at all assessment times. There was a correlation found between VM and BCVA and microperimetry parameters before surgery. The macular sensitivity (MS) as well as macular integrity index increased from 1 month to 6 months after PPV and were correlated with postoperative visual acuity (VA). There was a correlation found between the hole diameter and MS and P2 parameter 6 months after PPV. There was a correlation found between mean duration of symptoms of FTMH and VA and VM score. Conclusions. VM scores seem to correlate better than HM scores with preoperative BCVA, microperimetry parameters, and duration of symptoms of the FTMH. VM scores are higher after PPV than HM scores in patients with stage 4 of the FTMH. This trial is registered with NCT03701542.

Purpose. Internal limiting membrane (ILM) peeling is important for macular hole (MH) surgery but may have secondary effects visible on spectral domain optical coherence tomography (OCT) and multifocal electroretinography (mfERG). We relate integrity of inner and outer macular layers with functional results with mfERG. Methods. Nonrandomized prospective study of 33 consecutive eyes of 33 patients with macular hole who underwent vitrectomy with ILM peeling. Best-corrected visual acuity was assessed, and integrity of external layers was measured using OCT. Each component of mfERG, N1 and P1 amplitude and latency, was also measured. Results. All eyes showed macular hole closure. Visual acuity improved from 20/400 to 20/40 in the Snellen visual acuity chart (P<0.001), and OCT external lines were intact in 19 eyes and disrupted in 14 eyes. Postoperatively, N1 and P1 amplitudes in ring 1 increased compared to preoperative values (P<0.001 for both). Latency remained delayed for both N1 and P1 wave. In the group of 19 eyes with integrity of outer retinal layers, N1 amplitude in ring 1 was superior to the group of 14 patients with disrupted outer retinal layers (P=0.042). Conclusions. In macular hole surgery, structure analysis in OCT is one of the important outcomes for the retinal surgeon. Functional results are parallel with anatomic results, but visual gain is limited. The limited recovery in mfERG suggests an alteration of retinal physiology that could explain limited vision recover.

Introduction: Postoperative eccentric macular hole (MH) formation is an uncommon complication after pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for epiretinal membrane or MH treatment. Herein, we present a case of eccentric MH formation after PPV with ILM peeling for MH. Case Description: A 72-year-old female patient underwent 23-gauge PPV with ILM peeling for idiopathic MH in her right eye. The visual acuity was 6/24 in the right eye. One week postoperatively the retina was attached and the MH seemed to be closed, while visual acuity was 6/12. One month after PPV, there was a single eccentric retinal hole below the macula, which was detected at the fundoscopy and was confirmed by OCT. The visual acuity was 6/9 and the patient referred no symptoms. No further intervention was attempted, and at the 6-month follow-up the visual acuity and the size of the eccentric MH remained stable. Conclusions: Eccentric MHs can develop after PPV and are usually managed conservatively by observation.

We report a case of ocular toxoplasmosis that developed a full-thickness macular hole (FTMH) which was successfully treated by pars plana vitrectomy combined with an inverted internal limiting membrane (ILM) flap. A 49-years-old Japanese man was aware of blurred vision in his right eye. Slit-lamp biomicroscopy, ophthalmoscopy, and optical coherence tomography (OCT) of the right eye showed that there was a grayish-white subretinal lesion at the macula accompanied by retinal exudation and mild vitreous flare and iritis. An increase in the level of serum IgM for toxoplasma led to a diagnosis of ocular toxoplasmosis. He developed a FTMH adjacent to the lesion 2 weeks after administering sulfamethoxazole/trimethoprim, and his decimal visual acuity was 0.15. Because the FTMH remained 3 months after the resolution of inflammation and his metamorphopsia persisted, vitrectomy with an inverted ILM flap was performed. After the surgery, the visual acuity improved to 0.2 with the closure of the FTMH confirmed by OCT. A FTMH in an eye with ocular toxoplasmosis was successfully closed by vitrectomy with an inverted ILM flap.

Purpose. To evaluate the efficacy of internal limiting membrane (ILM) peeling combined with modified flap inverting under air in the treatment of large idiopathic macular hole (MH). Methods. Eyes with a large idiopathic MH (minimum diameter >550 μm) were included in this study. The surgical procedure included standard 23-gauge pars plana vitrectomy (PPV), ILM peeling, complete fluid-gas exchange, and ILM flap inversion under air. The patients underwent follow-up exam including optical coherence tomography (OCT) and best-corrected visual acuity (BCVA) measurement. Results. Sixteen eyes from 16 patients were included. Mean MH diameter was 681.43 ± 112.12 μm. After a mean follow-up time of 6.25 ± 2.65 months, in all cases, the MH was closed, and the ILM flap could be seen at the inner surface of the fovea. U-shaped and V-shaped MH closure was achieved in 11 and 5 cases, respectively. The BCVA improved significantly from 1.49 ± 0.35 logMAR to 0.89 ± 0.35 logMAR ( p < 0.05 ), and visual acuity of 20/100 or better was achieved in 8 eyes. Conclusion. ILM flap inverting under air was helpful in improving the functional and anatomic outcomes of vitrectomy for large idiopathic MH.

The aim of this manuscript is to describe a novel retinal finding of Alport syndrome during surgical management of an associated macular hole. A retrospective chart review of a 65-year-old man with a diagnosis of Alport syndrome confirmed by renal biopsy was found to have an associated full-thickness macular hole. Pars-plana vitrectomy surgery with internal limiting membrane (ILM) peeling was attempted, but intraoperatively the ILM was found to be absent at the macula. Alport syndrome may be associated with the absence of the ILM. This can complicate attempts at macular hole repair.

Hole Closure

Herein, we report the longitudinal observation of a case with reopening of the macular hole associated with a lamellar macular hole-associated epiretinal proliferation (LHEP) followed by spontaneous closure in patients with stage 2 idiopathic macular hole. A 64-year-old woman was referred for the decreased visual acuity (VA) and acute anorthopia in the right eye. Funduscopy and optical coherence tomography (OCT) showed stage 2 full-thickness macular hole without posterior vitreous detachment (PVD) and operculum formation. Her best-corrected visual acuity (BCVA) was 20/32. One month later, the diameter of the macular hole was getting small and VA improved. Six months later, the macular hole was treated spontaneously with the attached hyaloid membrane to the macula by OCT and the BCVA improved to 20/20. Fourteen months after the first visit, the BCVA decreased to 20/50 and the patient was diagnosed with stage 4 macular hole with complete PVD. OCT showed full-thickness macular hole with a LHEP in the right eye. After 25G-gauge vitrectomy with the peeling of internal limiting membrane (ILM) and LHEP, the macular hole was closed and BCVA finally improved to 20/25. Spontaneous macular hole closure without PVD may rarely occur in patients with LHEP. The surgical removal of ILM and LHEP may contribute to the successful macular hole closure after vitrectomy.

Background: Previous studies have shown that epiretinal membranes (ERMs) may be associated with abnormal outer retinal anatomy. However, long-term morphological and functional results of pars plana vitrectomy (PPV) with ERM and internal limiting membrane (ILM) peeling in eyes with central bouquet (CB) alterations have not yet been investigated. Methods: In a retrospective, consecutive study all patients underwent best corrected visual acuity (BCVA) testing and spectral domain optical coherence tomography (SD-OCT) before and after a mean of 20 months (range 3–70 months) postoperatively. CB abnormalities and ERMs were classified according to Govetto’s staging systems. Results: Of the 67 eyes, 22 (34%) showed CB abnormalities at baseline. The mean BCVA increased from 0.42 at baseline to 0.20 LogMAR at final follow-up (p < 0.001). Neither ERM stage (p = 0.06) nor CB stage (p = 0.939) at baseline were significant predictors of vision improvement following surgery. Conclusions: Our results show that baseline BCVA, but not classification of CB changes and ERM at baseline, seems to be a useful predictor for functional outcomes following PPV with ERM and ILM peeling in the long-term.

Myopic Macular Hole

PurposeThe aim of this study was to determine the effect of the inverted internal limiting membrane (ILM) flap technique on the macular hole (MH) closure and foveal microstructure recovery of patients with highly myopic MH.MethodsPars plana vitrectomy and gas tamponade with the inverted ILM flap technique (19 eyes) or with the ILM peeling technique (21 eyes) were performed in patients with highly myopic MH with or without retinal detachment. The rate of MH closure and retinal reattachment, the reconstructive anatomical change of the foveal microstructure and the best-corrected visual acuities (BCVA) of the two groups were compared.ResultsThe anatomic closure rate was statistically significantly higher in the inverted group (100%) than in the peeling group (66.7%; p=0.009). All eyes with MH retinal detachment had successful retinal reattachment in these two groups. However, the rate of the external limiting membrane (ELM) and ellipsoid zone (EZ) (p=0.020), as well as gliosis (p=0.049) in macular area, detected by OCT, was significantly greater in the inverted group than in the peeling group. The postoperative BCVA was significantly better in the eyes with ELM, EZ (p=0.031) and gliosis (p=0.008), but without hyperreflective foci (p=0.001).ConclusionsThese findings demonstrate that the inverted ILM flap technique has better efficacy than the ILM peeling technique for patients with myopic MH in closure rate, foveal microstructure and postoperative BCVA.
