PURPOSE
To investigate if the ratio of the preoperative nasal and temporal "arms" of the macular hole (MH) can have a predictive value in the magnitude of foveal displacement postoperatively.
METHODS
This is retrospective interventional case series of eyes of 40 patients with full-thickness macular hole (FTMH), which underwent vitrectomy with internal limiting membrane (ILM) peeling and had Type 1 closure.All subjects underwent pre and postoperative optical coherence tomography (OCT, Heidelberg, Spectralis, Germany). Their pre and postoperative foveo-papillary distance (FPD) was measured and the magnitude of shift was calculated. The nasal and temporal arm lengths, their ratio (N/T ratio), and the hole base diameter were measured in the preoperative OCTs.The main outcome measure was the correlation of the N/T ratio with the postoperative foveal displacement.
RESULTS
We observed that in 25% (n = 10) the fovea shifted temporally; in 75% (n = 30) it shifted nasally. The shift did not show a significant correlation with either N/T ratio (r = 0.155, P = 0.34) or with base diameter (r = -0.008, P = 0.961). The odds ratio (OR) was 4.92 (P = 0.04) and the relative risk (RR) was 3.12 (P = 0.039) for a longer temporal segment to predict a temporal shift.
CONCLUSION
Both nasal and temporal shifts are possible after successful hole closure and temporal shifts can also occur in a significantly high proportion of patients. Temporal shifts are more likely in eyes with a longer temporal segment.

To analyze the changes in each retinal layer and the recovery of the ellipsoid zone (EZ) after full-thickness macular hole (FTMH) surgery. Patients who underwent surgery for FTMH were included. Spectral-domain optical coherence tomography (SD-OCT) was performed preoperatively and postoperatively at 1, 3, 6, 9, and 12 months. A total of 32 eyes were enrolled. Ganglion cell layer, inner plexiform layer, and inner nuclear layer showed significant reductions over time after surgery (P = 0.020, P = 0.001, and P = 0.001, respectively), but were significantly thicker than those of fellow eyes at 12 months postoperatively. The average recovery duration of the external limiting membrane (ELM), outer nuclear layer (ONL), and EZ was 1.5, 2.1, and 6.1 months, respectively. Baseline best-corrected visual acuity (BCVA) (P = 0.003), minimum linear diameter (MLD) (P = 0.025), recovery of EZ (P = 0.008), and IRL thickness (P < 0.001) were significant factors associated with changes in the BCVA. Additionally, axial length (P < 0.001), MLD (P = 0.020), and IRL thickness (P = 0.001) showed significant results associated with EZ recovery. The IRL gradually became thinner after FTMH surgery but was still thicker than that of the fellow eye at 12 months postoperatively. The recovery of ELM and ONL may be a prerequisite for the EZ recovery. The BCVA change was affected by baseline BCVA, MLD, recovery of EZ, and IRL thickness. Additionally, axial length, MLD, and IRL thickness were significantly associated with EZ recovery.

Korean Journal of Ophthalmology : KJO Apr 2021To assess the prevalence and progression of a stage 0 macular hole in the fellow eye of patients with an idiopathic full-thickness macular hole.
PURPOSE
To assess the prevalence and progression of a stage 0 macular hole in the fellow eye of patients with an idiopathic full-thickness macular hole.
METHODS
The fellow eyes of 189 patients who underwent idiopathic full-thickness macular hole surgery were examined by biomicroscopy and spectral domain-optical coherence tomography (SD-OCT). A subset of 21 fellow eyes with a stage 0 macular hole was observed. Changes in the macular hole were evaluated by biomicroscopy and SD-OCT for an average of 29 months.
RESULTS
Among the 21 eyes, 15 showed no change in perifoveal vitreous detachment (71.4%). Two eyes (9.5%) developed complete vitreofoveal separation, and one of the two developed a separation after progression to stage 1A. Among 21 eyes, 5 (23.8%) developed above stage 1A, and one of the five progressed to stage 1B after five years, which was successfully treated with vitrectomy and gas tamponade.
CONCLUSIONS
Perifoveal vitreous detachment in the fellow eye on SD-OCT, defined as a stage 0 macular hole, occurred at an earlier phase than stage 1A macular holes and may progress to an advanced stage. Therefore, patients who undergo macular hole surgery and have a stage 0 macular hole or perifoveal vitreous detachment in the fellow eye should be followed closely.

PURPOSE
To evaluate the relationship between patient outcome and surgical experience by developing an objective quality measure of macular hole surgery based on forceps damage to the inner retina.
METHODS
We retrospectively examined 3 macular hole case series >1 year after pars plana vitrectomy, internal limiting membrane peeling and gas tamponade. The patients were operated by (1) a novice surgeon (<20 cases), (2) an intermediate (150+ cases) and (3) an experienced surgeon (2000+ cases). Primary outcome was inner retinal volume defect as segmented from optical coherence tomography (GCL++: thickness from internal limiting membrane to inner plexiform layer). Secondary outcome was retinal function measured by confocal microperimetry using a custom scanning protocol.
RESULTS
Thirty-two patients were examined: 11, 10 and 11 patients in the novice, intermediate and experienced surgeon group, respectively. Median GCL++ volume defect was 23.68 × 10 μm (IQR: 22.77 × 10 -44.81 × 10 μm ), 8.42 × 10 μm (IQR: 4.86 × 10 -10.03 × 10 μm ) and 3.55 × 10 μm (IQR: 1.44 × 10 -7.94 × 10 μm ) in the novice, intermediate and experienced surgeon group, respectively (p = 0.0004). The novice surgeon volume defect differed significantly from the intermediate and experienced surgeon (p = 0.016 and p = 0.0002, respectively). A subset of 12 patients underwent microperimetry measurements demonstrating correlation between inner retinal volume defect and reduced retinal sensitivity (p = 0.02).
CONCLUSIONS
Forceps induced inner retinal damage commonly occurs during initiation of internal limiting membrane peeling in macular hole surgery. Damage to the structure and function of the inner retina seems to correlate to surgical experience.

OBJECTIVE
Postoperative eccentric macular hole formation is a rare complication after vitrectomy with internal limiting membrane peeling for a macular hole. We report a rare case of late eccentric macular hole formation following successful macular hole surgery.
CASE REPORT
A 73-year old woman was referred with a long standing full thickness macular hole in both eyes. The patient underwent sequential cataract surgery, 23 gauge sutureless pars plana vitrectomy with internal limiting membrane peeling and inverted flap in both eyes. Control examination six months after the surgery revealed best corrected visual acuity of 20/40 in both eyes, complete closure of the macular hole, with retinal atrophy in both eyes. Control examination eighteen months after the surgery revealed a stable finding in the right eye and an eccentric temporal macular hole in the left eye. The patient was closely observed for one year with no signs of visual acuity reduction or macular hole changes.
CONCLUSION
Postoperative eccentric macular holes may occur after a long follow up period. Most cases remain stable for a long period of time and do not require further surgical intervention. This case highlights the need for close monitoring of patients after macular hole surgery with internal limiting membrane peeling.

BACKGROUND
An idiopathic macular hole (IMH) is a full-thickness anatomic defect extending from the internal limiting membrane to the photoreceptor layer of the macula without any known cause. Recently, clinical laboratory markers of systemic inflammatory status derived from complete blood counts have been evaluated in ocular diseases. This study aimed to explore whether they could predict the development and progression of IMHs.
METHODS
A retrospective review of 36 patients with IMH and 36 sex-and-age-matched patients with cataracts was conducted. We collected complete blood counts of all participating individuals and calculated systemic immunoinflammatory indicators. The maximum base diameter of the IMH (BD), minimum diameter of the IMH (MIN), height of the IMH (H), area of the intraretinal cyst (IRC), and curve lengths of the detached photoreceptor arms were measured on optical coherence tomography (OCT) images. We used these values to calculate the macular hole index (MHI), tractional hole index (THI), diameter hole index (DHI), hole form factor (HFF), and macular hole closure index (MHCI). We performed a receiver operating characteristic (ROC) curve analysis of 30 patients with IMH who were followed up 1 month after surgery.
RESULTS
Lymphocyte counts were significantly higher in the IMH group. No other significant differences were observed between the IMH and control groups. Lymphocyte counts in the IMH group were significantly negatively correlated with MIN and BD and were significantly positively correlated with MHI, THI, and MHCI. However, lymphocyte counts were not significantly correlated with H, IRC, DHI, and HFF. In the ROC analysis, BD, MIN, MHI, THI, and MHCI were significant predictors of anatomical outcomes. According to the cut-off points of the ROC analysis, lymphocyte counts were compared between the above-cut-off and below-cut-off groups. Lymphocyte counts were significantly higher in the MIN ≤ 499.61 μm, MHI ≥ 0.47, THI ≥ 1.2, and MHCI ≥ 0.81 groups. There were no significant differences between the above-cut-off and below-cut-off BD groups.
CONCLUSIONS
Although inflammation may not be an initiating factor, it may be involved in IMH formation. Lymphocytes may play a relatively important role in tissue repair during the developmental and postoperative recovery phases of IMH.

BACKGROUND
Postoperative face-down positioning (FDP) for up to 2 weeks is believed to be necessary for successful closure of macular holes. FDP, however, can be disabling and uncomfortable and is a major burden for elderly patients. The aim of this study was to investigate how nonsupine posturing and macular hole size affect anatomical and functional success of macular hole closure.
METHODS
The medical records of patients with idiopathic macular holes who were treated surgically between 2016 and 2019 were reviewed retrospectively. Exclusion criteria included vitreomacular traction, previous retinal detachment, or chronic macular hole.
RESULTS
A total of 115 eyes of 115 patients were included. Average age was 69.2 ± 8.2 years; 63 patients (55%) were female. Anatomical success was achieved in 108 patients (94%) with a single operation. In small holes (<400 μm), closure was seen in 98% of cases (95% CI, 94%-100%); in large holes (≥400 μm), 90% of cases (95% CI, 76%-94%). Visual acuity remained stable or improved in 108 patients (92%). Average preoperative best-corrected visual acuity was 1.02 ± 0.45, with an overall improvement of 5 lines postoperatively. Small holes and large holes improved, with an average of 3 versus 7 lines gained, respectively.
CONCLUSIONS
In this study cohort, favorable anatomical and functional outcomes were achieved without postoperative FDP. These outcomes are comparable to the traditional FDP approach.

BACKGROUND
Blunt trauma to the eye can present with varied manifestations involving both the anterior and posterior segments of the eye. Giant retinal tear (GRT) following trauma occurs most commonly at the equatorial region or anterior to the equator. GRT posterior to the equator is rare.
PURPOSE
To demonstrate the successful management of a post-traumatic posterior GRT and full-thickness macular hole (MH) associated retinal detachment (RD).
SYNPOSIS
A 21-year-old-male presented with sudden diminution of vision in the right eye (RE) following blunt-trauma with cricket ball. RE vision at presentation was hand movement close to face. Anterior segment of RE revealed pupillary sphincter tear, posterior synechiae and posterior subcapsular cataract (PSC). RE fundus revealed a posterior-GRT, full thickness MH, mild vitreous haemorrhage and rhegmatogenous RD. He was managed with pars plana vitrectomy, encircling scleral band, perfluorocarbon liquid-assisted flattening of GRT, internal limiting membrane peeling, and endotamponade. Post-operatively the retina was attached, MH was closed and the patient achieved an ambulatory vision of 1/60.
HIGHLIGHTS
This video demonstrates the successful management of a posterior-GRT and MH associated RD. Removal of adherent hyaloid from the long anterior flap of posterior GRT, peeling of ILM from temporal narrow mobile strip of retina (which has a risk of radial extension of GRT edges) and manoeuvring in suboptimally dilated pupil are illustrated in this video.

PURPOSE
To investigate morphological and functional outcomes of the inverted internal limiting membrane (I-ILM) flap technique in large (≥ 400 μm) idiopathic full-thickness macular holes (FTMH) over a follow-up period of 12 months.
METHODS
In this retrospective study, 55 eyes of 54 consecutive patients were enrolled. Best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT, Heidelberg, Spectralis) were performed preoperatively as well as 1, 3, 6, 9, and 12 months postoperatively. Special focus was put on the reintegration of outer retinal layers and the different ILM flap appearances.
RESULTS
FTMH closure rate was 100% (55/55). BCVA significantly improved over the follow-up period of 12 months from 0.98 ± 0.38 LogMAR preoperatively to 0.42 ± 0.33 LogMAR at 12 months postoperatively (p < 0.001). There was no significant correlation between the three different ILM flap appearances and BCVA. Better preoperative BCVA, complete restoration of the external limiting membrane (ELM), higher macular hole index (MHI), and smaller MH base diameter were associated with higher improvement of BCVA.
CONCLUSION
Our study highlights the favorable morphological and functional outcomes of the I-ILM flap technique in the short as well as in the long term. While complete ELM restoration revealed to be an important factor for improvement in BCVA, the different postoperative ILM flap appearances seem not to be related to BCVA.

PURPOSE
To analyse morpho-functional foveal changes in eyes with lamellar macular hole (LMH) by an integrated assessment of short-wavelength fundus autofluorescence (SW-FAF) and microperimetry (SW-FAF/microperimetry integrated assessment) before and after treatment with a technique of double-inverted flaps of epiretinal proliferation (EP) and internal limiting membrane (ILM).
METHODS
Clinical and tomographic parameters were best-corrected visual acuity (BCVA), LMH size, central retinal thickness (CRT) and outer retinal layer integrity. SW-FAF/microperimetry integrated assessment allowed to analyse retinal sensitivity (RS) and FAF status of the fovea by an overlay of RS map on SW-FAF image. Follow-up was at baseline, 1, 3, 6 and 12 postoperative months.
RESULTS
Forty pseudophakic eyes. Hyper-FAF area was associated with larger LMH size (p = 0.0073) and inversely correlated with CRT (p = 0.021). Lower preoperative RS was observed in hyper-FAF than normo-FAF areas (p = 0.0117). External limiting membrane (ELM) defect was associated with worse BCVA (p = 0.0004). After surgery, BCVA improved (p = 0.001) and it was related to ELM recovery (p = 0.00483), hyper-FAF area decreased (p = 0.001), and RS increased (p = 0.440). Hyper-FAF points that normalized their FAF were associated with higher RS improvement compared to unchanged points.
CONCLUSION
Short-wavelength fundus autofluorescence/microperimetry integrated assessment provides important information on the entity of damage of LMH and on postoperative recovery. Double-inverted EP and ILM flap technique is safe and effective for LMH treatment.
