“…The macular hole index that can reflect the prognosis of the surgery and its visual outcome has been gaining popularity among the publications on the macular hole and it’s now been used as a useful predictor for the physiological outcome of MH. 22 , 23 The determination of the macular hole index as was obtained in this study are of easy application, therefore, the better outcome of the surgical procedure can be pre-operatively determined. The functional results found in this study are comparable to those of literature, 24 , 25 showing that MHI is a good predictive factor for FTMH surgery outcome.…”

Objective: To determine the effectiveness of macular hole index (MHI) as a predicting factor of visual outcome after full thickness macular hole surgery. Methods: This quasi-experimental study was conducted at LRBT Free Base Eye Hospital, Karachi from January 2018 to March 2019. Total 45 eyes of 45 patients with full thickness macular hole (FTMH) underwent preoperative Best Corrected Visual Acuity (BCVA) assessment with logMar chart and Optical Coherence Tomography (OCT) scanning, with measurement of base diameter and macular hole height. Values were calculated for the macular hole index (MHI), which was taken as the predictive factor. All patients had undergone 25+G trans-conjunctival three ports pars plana vitrectomy, internal limiting membrane peeling, and endo-tamponade of C3F8 (14%). The final visual outcome of all the patients was noted. Results: Forty-five patients were included for the study, out of which 10 (22.2%) were male and 35 (77.7%) were female. Age ranged from 45-70 years (mean age 57.20±6.47 years). The mean pre-operative visual acuity was 2.46±1.15 logMar and was 3.88±2.00 logMar, post-operatively. Moreover, 27(60.0%) out of 45 patients achieved BCVA (gain of 2 lines of the logMar chart). The average macular hole index was 1.55±0.50 and out of 45, 25 patients had MHI ≥0.5. It was found that patients with macular hole index ≥0.50 showed clinically significant improvement in BCVA in comparison to those who have macular hole index <0.50. Conclusion: Macular hole index can be used to predict functional success in macular hole surgery. doi: https://doi.org/10.12669/pjms.36.5.1995 How to cite this:Feroz L, Rizvi SF, Naz S, Khan MTH.

“…Among preoperative factors, two well established are symptom duration and preoperative VA. The other factors are patient age and OCT parameters such as stage of FTMH, minimum diameter or/and base diameter of the FTMH, central subfield retinal thickness, height of the FTMH and diameter of internal/external segments layer IS/OS, and external limiting membrane (ELM) defects [5, 21, 22]. However, these parameters are anatomical, imaging-based features, and to estimate the result of FTMH surgery, functional tests are required too.…”

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.

“…M and N were the curve lengths of the detached photoreceptor arms, and BASE was the length of the retinal pigment epithelial layer (RPE layer) detaching from the photoreceptors. Some studies used central subfield retinal thickness (CSRT) to predict anatomical results of MH surgery, but the results were contradictory [ 32 , 33 ].…”

Background: To determine whether preoperative hole diameter ratio (HDR) is a predictive factor for postoperative anatomical outcome for stage III or IV idiopathic macular holes (IMHs). Methods: One-hundred and one eyes with stage III or IV IMH were included in this retrospective case series study. All cases were treated with vitrectomy combined with internal limiting membrane (ILM) peeling and room air tamponade. The macular hole (MH) minimum and maximum diameter was measured on preoperative optical coherence tomography (OCT) images. The HDR was defined as the minimum to maximum diameter ratio. Results: Eighty-one eyes (80.2%) got a Type I closure after surgery (group A). Postoperative unclosed MHs were found in 20 eyes (19.8%) (group B). The preoperative minimal diameter (703.6 ± 116.1 μm vs. 597.6 ± 120.1 μm, P < 0.01) and HDR (0.6 ± 0.1 vs. 0.5 ± 0.1, P = 0.01) were both significantly smaller in postoperative closed eyes. The closure rate of IMHs with HDR < 0.6 was significantly higher than those with HDR ≥ 0.6 (90.2% vs. 65.0%P = 0.002). Conclusions: Preoperative HDR < 0.6 is predictive for a good postoperative anatomical outcome in stage III or IV IMHs.

Abstract: Preoperative central subfield retinal thickness is a strong and probably the best predictor of anatomical results of IMH surgical treatment.
