“…A correlation between a low MFT and poor preoperative VA has been detected in a study by Holland 1 on 89 eyes. The observation of patients with relatively well-preserved VA and MFT will thus be followed and observed according to current procedures.…”

“…The observation of patients with relatively well-preserved VA and MFT will thus be followed and observed according to current procedures. On the contrary, Holland et al 1 also found a significant correlation between the level of pre- and post-operative VA: the better preoperative VA, the better the postoperative VA gets. In such cases, it will be beneficial to perform PPV on the majority of these patients, to ensure the VA improves as much as possible.…”

Purpose To analyze the functional and anatomical parameters of lamellar macular hole (LMH) surgery with internal limiting membrane peeling and determine which surgical technique provides the best visual outcome. Methods This is a retrospective multicenter cross-sectional study on patients who underwent pars plana vitrectomy (PPV) for LMH with or without combined phaco-vitrectomy, as well as gas-, air- or BSS-tamponade. Pre- and postoperative examination included best corrected visual acuity (BCVA) measurements for functional comparison and optical coherence tomography (OCT) scans to determine the contributing anatomical parameters. Results A total of 66 consecutive patients were included (age: 71.79 ± 8.52 years), of which 47 (71.2%) were diagnosed as tractional type LMH, and 19 patients (28.8%) as degenerative type. An epiretinal membrane (ERM) was present in 63 of the patients (95.5%), LMH-associated epiretinal proliferation (LHEP) was present in 19 patients (28.8%), and 16 patients (24.2%) had concomitant ERM and LHEP. In the group of tractional LMH, the mean central foveal thickness (CFT) was 81.1% thicker (P < 0.05) than in the degenerative group. Thirty-one patients (47.0%) underwent a combined phaco-vitrectomy procedure, while the rest underwent 23G, 25G or 27G PPV. Seventeen of the 66 patients received gas-tamponade (25.7%)-either SF 6 or C 3 F 8 , 26 received air-tamponade (39.4%), while the remaining 23 patients received balanced salt solution (BSS)-tamponade (34.9%) during vitrectomy. The total BCVA showed significant improvement postoperatively (p < 0.001) and accordingly in the following groups: tractional LMH type (p < 0.001), degenerative type (p < 0.001), simple PPV (p < 0.001), phaco-vitrectomy (p < 0.001), BSS injection (p < 0.01), gas-tamponade (p < 0.05). None of the patients included in the study developed a full thickness macular hole postoperatively. Conclusion PPV provided a high success rate and functional improvement for treating LMH for both tractional and degenerative types, as well as combined phaco-vitrectomy treatment when cataract was present.
