“…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. We did not find any correlation between gender and age with the outcome of macular hole surgery.…”

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.

“…This findings are in line with the result of this study which found that those who waits ≤ 6 months had better outcome than ≥6 months at 68.8% and 31.2% respectively. Furthermore, according to Venkatesh et al 32 The duration of onset under 6 months is one of the functional success factors, namely a better improvement in VA after the closure of MH. 5,21,22 In MH that has occurred for more than 2-3 years, the reported success rate is lower (63%) and visual acuity is worse than early MH.…”

Introduction: This study aims to determine the anatomical and functional outcomes in patients with macular hole (MH) underwent vitrectomy with internal limiting membrane (ILM) peeling. Method: A descriptive retrospective study at Vitreoretinal Division of Ophthalmology Department, Faculty of Medicine Universitas Indonesia – Cipto Mangunkusumo National General Hospital (FKUI-RSCM). Secondary data obtained from medical records of patient with MH within January – December 2017. The anatomical outcome was observed from the closure of MH. Functional outcome was observed from post-operative visual acuity at day-1, month-1, month-3, and month-6. Results: 16 patients who met the criteria were included in this study. MH closure was observed in 43.8% of cases and failed closure in 56.2%. Improvement of visual acuity was observed on closure cases in 3 months and 6 months, occurred in 71.43% and 100% of cases, respectively. Conclusion: MH closure rate was 43.8%. Satisfying result of improvement in visual acuity achieved after vitrectomy with ILM peeling.

“…For example, THI is a ratio between maximum height to minimum hole diameter and accounts for antero-posterior traction where DHI signifies tangential traction on hole by evaluating the ratio of minimum hole diameter and base diameter. 14 Other indices like MHI and HFF can take into account both tangential and antero-posterior tractional forces in their calculations. Tractional Hole index has been positively co related with better visual outcomes at 3 months after macular hole surgery.…”

Objectives: The objective of this study was to assess the utility of novel macular hole indices of Optical Coherence Tomography (OCT) and predicting the functional outcome of surgery. Methods: This was a retrospective chart review of 28 eyes who underwent surgery for idiopathic Full Thickness Macular Hole (FTMH) at The Aga Khan University Hospital (AKUH), Karachi from January 2016 to March 2020. Data of preoperative OCTs were recovered from data server of OCT machine. Measurements of the pre-operative OCTs were calculated using caliper function of OCT software by two independent technicians. Parameters included Macular Hole Index (MHI), Traction Hole Index (THI), Hole Form Factor (HFF) and Diameter Hole Index (DHI) were recorded. Receiver operating characteristic (ROC) curve was used to evaluate the performance of DHI, THI, HFF and MHI for improved BCVA after surgery, by looking at sensitivity, specificity and area under curve (AUC). P-value of <0.05 was considered significant. Results: Out of 30 eyes, final data analysis was done for 28 eyes. Mean age was 61.5 ± 6.2 years. Mean pre-operative and 6 months post-operative LogMAR best corrected visual acuity (BCVA) was 0.84 ± 0.23 and 0.32 ± 0.30 (p-value <0.001). Area under the curve with 95% confidence interval estimated for DHI, THI, HFF, and MHI was [0.750 (0.559 to 0.889)], [0.827 (0.637 to 0.943)], [0.846 (0.660 to 0.954)], [0.827 (0.637 to 0.943)]. Cut off values for predicting good functional outcome (post-op BCVA equal or better that 0.4) for DHI, THI, HFF and MHI were 0.454, 1.086, 0.856 and 0.501 respectively. All ROC value of less than 0.5 were considered unlikely to predict functional outcomes with macular hole indices. Conclusion: Novel macular hole indices can be used as a tool to predict the functional outcomes of macular hole surgery. Larger studies may be required to assess their wider effectiveness. doi: https://doi.org/10.12669/pjms.37.5.4126 How to cite this:Tayyab H, Siddiqui R, Jahangir S, Hashmi S.
