Background: To identify prognostic preoperative and intraoperative factors for anatomical and visual success of idiopathic macular hole (MH) surgery. Methods: We conducted a non-randomized, collaborative multicenter study using data of 4207 MH surgery from 140 surgeons. Main study outcomes were anatomical closure and best corrected visual acuity (BCVA) improvement postoperative at 6-12 months. Results: Information on anatomical success was available for 4138 eyes of 4207 operations. Anatomical closure of MH was achieved in 85.7% (3546 eyes). Closure was higher in smaller MH (stages 1-2 versus stage 3: OR=0.35; stage 2 versus stage 4: OR=0.16, and in MH with shorter duration before the operation (OR=0.94). Macular Holes were more likely to close when dyes were used to facilitate internal limiting membrane (ILM) peeling (odds ratio=1.73 to 3.58). The most important predictors of postoperative BCVA were the preoperative BCVA (estimate=0.39, p<0.001) and closure of the macular hole (...

Ophthalmology, 1993
To surgically treat patients with macular holes, the authors previously reported both anatomic (re-attachment) and visual success (2 lines of improvement) in a series of 52 eyes. They now have operated on an additional 118 eyes using similar techniques, for a total of 170 eyes.
Macular holes: vitreoretinal relationships and surgical approaches
Eye, 2008
Idiopathic full-thickness macular holes develop as a result of anteroposterior and tangential traction exerted by the posterior vitreous cortex at the fovea. Vitreoretinal relationships during the development of macular holes can be demonstrated in detail by ocular coherence tomography, facilitating an improved understanding of their pathogenesis and guiding clinical management. Surgical strategies for the repair of macular holes are designed to relieve vitreofoveal traction and to promote flattening and reapposition of the macular hole edges by intraocular gas tamponade. A period of facedown positioning postoperatively is conventionally advised. However, the evidence to support this recommendation is weak and practice varies considerably. Surgical removal of the inner limiting membrane (ILM) is advocated to ensure thorough removal of any tangential tractional components including any residual cortical vitreous. Current evidence suggests that ILM peeling can improve anatomical outcomes but the effect on visual function is less predictable; unsuccessful attempts to peel the ILM can be associated with poor visual outcome. The use of vital dyes can facilitate visualisation of the ILM and help achieve complete, atraumatic peeling. Indocyanine green dye can enable high rates of macular hole closure but has been associated with poorer visual outcomes suggesting a dosedependent toxicity. Trypan blue dye offers an alternative that may have a more favourable risk profile. An improved understanding of vitreoretinal relationships may facilitate a tailored approach to surgery in individuals with macular holes. Vitrectomy to relieve anteroposterior traction is central in the management of all full-thickness holes. The use of long-acting gases, prolonged face-down positioning, and ILM peeling may be more valuable for larger holes, longstanding holes, and those that have failed to close following conventional surgery.

Results of Pars Plana Vitrectomy for Different Types of Macular Holes
Clinical Ophthalmology (Auckland, N.Z.), 2021
Purpose To compare different types of macular holes regarding the anatomic and functional success following pars plana vitrectomy (PPV) and internal limiting membrane (ILM) removal. Methods A retrospective review of all patients with macular holes treated by PPV, ILM removal with gas tamponade from January 2014 to July 2017 in Magrabi Eye Hospital. Results One hundred fifty-seven eyes of 153 patients were analyzed. The eyes were classified according to the etiology of macular hole into four groups: 79 eyes with idiopathic macular hole (IMH), 51 eyes with traumatic macular hole (TMH), 16 eyes with macular hole in diabetic patients (DMH) and 11 eyes with myopic macular hole (MMH). We classified the IMH group based on the International Vitreomacular Traction Study Classification according to size into 3 subgroups; subgroup 1: ≤250µ, subgroup 2: >250 to 400µ and subgroup 3: ≥400 µ. All types of macular hole showed statistically significant postoperative improvement in BCVA compared t...
Prospective Randomized Trial of Vitrectomy or Observation for Stage 2 Macular Holes
American Journal of Ophthalmology, 1996
To determine the risks and benefits of vitrectomy surgery in eyes with stage 2 macular holes. • METHODS: A multicentered, controlled, ran domized clinical trial was performed with partici' pation of 16 community and university-based ophthalmology clinics. Thirty-six eyes with stage 2 macular holes and 12 months of follow-up were studied. Pars plana vitrectomy with separation of the posterior hyaloid membrane and intraocular injection of perfluoropropane (C 3 F 8) was followed by postoperative face-down positioning for two weeks. This protocol was compared with observa tion alone. Outcome variables included anatomic closure of the macular hole, macular hole size, and four standardized measures of vision. • RESULTS: At 12 months, 15 (71%) of 21 eyes randomly assigned to observation progressed to stages 3 or 4, compared with three (20%) of 15 eyes randomly assigned to surgery (P < .006). Compared with eyes randomly assigned to obser vation, eyes randomly assigned to surgery had
Comparison of outcomes between 20, 23 and 25 gauge vitrectomy for idiopathic macular hole
International Journal of Retina and Vitreous, 2015
Purpose: To compare the results of 20, 23, 25 gauge pars plana vitrectomy (PPV) with two different gas tamponades for idiopathic macular hole (MH) in a multi-surgeon vitroretinal practice. Methods: In this comparative, retrospective, interventional case series, the medical charts of 142 eyes/130 patients were reviewed. Patients who matched our inclusion criteria: eye with stage 2, 3, or 4 MH that underwent 20, 23, or 25 gauge PPV, internal limiting membrane (ILM) peeling, and fluid-gas exchange from January, 2005 to May, 2012 and had at least 6 months follow-up. The best current corrected visual acuity (VA) and anatomical status of the MH were assessed by optical coherent tomography (OCT) at 6 months, 1 year, and 2 years after vitrectomy. Results: The MH closed successfully after primary vitrectomy in 86.5 % (20 gauge), 96.4 % (23 gauge), and 92 % (25 gauge). Preoperative VA median were 20\126 (20 gauge), 20\100 (23 gauge), and 20\80 (25 gauge). At 6 months and 2 years postoperative VA did not differ significantly between the 3 groups (p = 0.570, and 0.054 respectively). However, at 12 months postoperative VA median 20\60 (20 gauge), 20\69 (23 gauge), and 20\40 (25 gauge) differ significantly (p = 0.005) likely due to cataract changes. The final median postoperative VA (at 2 years) in 25 gauge PPV group was 20/40 which was better than final visual outcomes for 20, and 23 gauge PPV groups (20/50, and 20/55 respectively). The different was not a statistically significant. MH closed successfully in 96 % (C3F8), and 88.1 % (SF6) (p = 0.063). Preoperative median VA was 20/100 in both groups of gas. At 6 months, 1 year, and 2 years postoperative median VAs did not differ significant between the 2 groups (p = 0.076, 0.343, and 0.309 respectively). MH closed successfully in (96.9 %) 12-14 % C3F8, and (95.3 %) 15-16 % C3F8 (p = 0.611). MH closed in (82.1 %) 18-20 % SF6, and (96.4 %) 22-26 % SF6 (p=0.053). Conclusion: Based on the results of this study, 20, 23, and 25 gauge of PPV have similar MH closure rates and VA outcomes. SF6 at 22-26 % or C3F8 at 12-14 % achieved maximum closure rates.

To assess visual and anatomical outcome of full thickness macular hole (FTMH) surgery with ILM peeling using brilliant blue G dye. Thirty patients who had clinically evident macular hole were selected. Pre-operative Optical Coherence Tomography (OCT) was done. In all cases vitrectomy was performed via 23guage 3 ports pars plana (3PPV) vitrectomy system and Brilliant blue G dye, 0.5ml dye was injected over macula which resulted in light blue stain of ILM and peeling was performed around hole in circular motion and after gas fluid exchange gas tamponade with SF6 was done. Final visual and anatomical outcome was measured as postoperative BCVA and postoperative OCT at three months respectively. Descriptive statistics were computed. Paired t-test was applied. P value≤0.05 were considered as significant. There were 12 male and 18 female patients. The mean age was 57.40±4.76 years. The mean size of macular hole was 452.20±242.33μm. The mean duration of symptoms was 16.73±13.49 weeks. Mean ...

Purpose To evaluate anatomical and visual outcomes of pars plana vitrectomy (PPV) with internal limiting membrane peeling (ILMP) in large idiopathic full-thickness macular holes (FTMH). Predictive factors also formed part of the study. Patients and Methods A retrospective review of medical charts and optical coherence tomography images of patients with large idiopathic FTMH (≥400 µm) was conducted. Results One hundred and fifty-eight eyes of 155 patients with a mean age of 62.94±7.50 years were included in the study. Mean preoperative visual acuity (VA) was 1.26±0.36 logMAR. Mean preoperative minimum linear diameter (MLD) and basal linear diameter (BLD) were 644.89±136.85 µm and 1208.11±307.14 µm, respectively. At 12 weeks postoperative follow-up, FTMH closure rate was 61.39% and mean postoperative BCVA was 0.92±0.36 logMAR. Multivariate logistic regression analyses showed the anatomical outcome was significantly associated with BLD ≤1200 µm, preoperative vitreomacular interface (VM...
Stage III macular hole surgery
British Journal of Ophthalmology, 1993
Twelve macular holes in 12 patients underwent a pars plana vitrectomy and epiretinal membrane resection with intravitreal gas tamponade for repair of their macular holes. The patients had stage Ill macular holes and had previously undergone a normal funduscopic examination within 2 years. The patients have been followed for a mean of 14 months (range 12-18 months) postoperatively. The results show that visual acuity improvements were not seen until at least 6 months after surgery if the hole was closed successfully. Seven holes were closed (58.3%) and all improved their best corrected visual acuity by more than two Snellen lines. In the five eyes that did not demonstrate hole closure (41-6%), one eye improved by two lines as well. The other four eyes remained at their preoperative acuity. One eye developed a dialysis which responded to a fluid air exchange and cryopexy (8.3%). Three eyes developed minimal lenticular opacities during the follow up period (25%). One eye demonstrated an altered perifoveal pigment epithelium perhaps related to intraoperative light toxicity. Macular hole surgery can restore some central acuity even in patients with longstanding holes. (Br_J Ophthalmol 1993; 77: 555-558)
