Ophthalmol Retina 2024; 8:465-472. [PMID: 37972892 PMCID: PMC11070309 DOI: 10.1016/j.oret.2023.10.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 10/23/2023] [Accepted: 10/27/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVE To identify preoperative OCT markers that correlate with postoperative visual acuity (VA) changes in eyes with lamellar macular hole (LMH) and epiretinal membrane foveoschisis (ERMF) after pars plana vitrectomy (PPV). DESIGN Cross-sectional retrospective study. SUBJECTS Patients seen at the Wilmer Eye Institute between 2011 and 2021 with an International Classification of Diseases, Ninth Revision, or International Classification of Diseases, 10th Revision, code for "macular hole" that underwent PPV, and demonstrated all OCT criteria present for either LMH or ERMF based on the Hubschman et al (2020) classification. METHODS OCT markers including hole dimensions, retinal layer continuity, and ellipsoid zone (EZ) convexity and pixelated intensity were quantified. Visual acuity immediately before PPV and at the last follow-up date available were both recorded. MAIN OUTCOME MEASURES Preoperative OCT variables that are correlated with postoperative changes in VA. RESULTS Forty-two eyes from 42 patients with LMH (n = 11) and ERMF (n = 31) that underwent PPV were identified. Visual acuity in the ERMF cohort significantly improved at last follow-up compared with preoperative VA (P < 0.001), whereas VA in the LMH cohort did not (P = 0.14). In the LMH cohort, retinal layer continuity at the hole edge was positively correlated with change in VA at final follow-up, whereas hole height was negatively correlated with VA. In the ERMF cohort, preoperative VA was negatively correlated with change in VA at final follow-up. CONCLUSIONS Retinal layer continuity at the hole and hole height are novel preoperative markers that predict postoperative VA change in LMH. After identifying the type of macular lesion, surgeons should consider using these preoperative OCT markers when counseling patients on potential postoperative VA outcomes and when managing patient expectations.

Graefes Arch Clin Exp Ophthalmol 2023; 261:3395-3401. [PMID: 37542557 DOI: 10.1007/s00417-023-06196-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 07/17/2023] [Accepted: 07/27/2023] [Indexed: 08/07/2023] Open
Abstract
PURPOSE To propose a novel technique of an internal limiting membrane (ILM) flap using ophthalmic viscoelastic device (OVD) with no requirement for postoperative head posture for the treatment of lamellar macular hole (LMH) repair. METHODS A retrospective analysis of 16 consecutive eyes of LMH patients who underwent vitrectomy with ILM flap with OVD. Best-corrected visual acuity (BCVA), central macular thickness (CMT), simultaneous cataract extraction, and ellipsoid zone disruption preoperatively and at the final follow-up were compared. RESULTS The mean age was 73.19 ± 7.26 years, and ten patients (62%) were females. The mean follow-up was 5.06±1.43 months (range 3-6). For all patients, BCVA was significantly improved at the final visit, from 0.65±0.36 logMAR units to 0.42±0.29 (p < 0.001). None of the patients had visual loss. Six patients had epiretinal membrane (ERM) foveoschisis, and the rest had LMH with epiretinal proliferation. Both subgroups presented a significant improvement in their BCVA with a trend for better improvement in the latter (p=0.09). Ellipsoid zone disruption was seen in 7 patients including one patient with a macular scar. There was no significant effect of ellipsoid zone disruption on the final BCVA (p=0.33). Twelve eyes (75%) underwent simultaneous cataract extraction. Mean BCVA at the final postoperative visit improved regardless of whether the eyes underwent simultaneous cataract surgery (p=0.39). CMT was also significantly improved at the final visit, from 200.06±46.8 μm preoperatively to 305.00±85.5 μm (p<0.001). No full-thickness macular holes were developed postoperatively. No intraoperative or postoperative complications were observed. CONCLUSIONS Treatment of LMH with ILM flap with OVD showed promising anatomical and functional results with no postoperative head position requirements.

Abstract
With the recent advent of high-resolution optical coherence tomography (OCT), atypical epiretinal tissue (AET), also known as epiretinal proliferation, has been frequently noted in various pathologies. AET presents as premacular tissue with homogenous medium reflectivity over the internal limiting membrane on OCT. Although AET is most frequently associated with a lamellar hole (LH), some cases of macular hole (MH) also accompany AET at the edge of the hole. MH with AET has been reported to have worse clinical and surgical outcomes than MH without AET. The imaging and histopathological findings of AET imply that the development of MH with AET may not have been driven by vitreofoveal traction. Instead, MH with AET might have evolved from LH with AET. This mini-review encompassed relevant studies on MH with AET published to date and explained the clinical, prognostic, and pathogenic significance of AET in MH in detail.

Primary Lamellar Macular Holes: To Vit or Not to Vit. J Clin Med 2022; 11:jcm11175046. [PMID: 36078977 PMCID: PMC9457236 DOI: 10.3390/jcm11175046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/21/2022] [Accepted: 08/26/2022] [Indexed: 11/19/2022] Open
Abstract
There is a wide spectrum of macular conditions that are characterized by an irregular foveal contour caused by a break in the inner fovea. These include full-thickness macular hole (FTMH), foveal pseudocyst, lamellar macular hole (LMH) and macular pseudohole (MPH). Clinical examination of vitreomacular interface disorders is notoriously poor in differentiating these conditions. These conditions were initially described with slit-lamp biomicroscopy, and the main goal was to distinguish an FTMH from the others. The introduction of optical coherence tomography (OCT) has revolutionized our understanding of the foveal microstructural anatomy and has facilitated differentiating these conditions from an FTMH. However, the definitions of the other conditions, particularly LMH, has evolved over the past two decades. Initially the term LMH encompassed a wide spectrum of clinical conditions. As OCT became more widely used and observations became more refined, two different phenotypes of LMH became apparent, raising the question of different pathogenic mechanisms for each phenotype. Tractional and degenerative pathological mechanisms were proposed. Epiretinal membranes (ERMs) associated with each phenotype were identified. Typical ERMs were associated with a tractional mechanism, whereas an epiretinal proliferation was associated with a degenerative mechanism. Epiretinal proliferation represents Müller cell proliferation as a reactive process to retinal injury. These two types of ERM were differentiated by their characteristics on SD-OCT. The latest consensus definitions take into account this phenotypic differentiation and classifies these entities into LMH, MPH and ERM foveoschisis. The initial event in both ERM foveoschisis and LMH is a tractional event that disrupts the Müller cell cone in the foveola or the foveal walls. Depending on the extent of Müller cell disruption, either a LMH or an ERM foveoschisis may develop. Although surgical intervention for LMH remains controversial and no clear guidelines exist for pars plana vitrectomy (PPV), eyes with symptomatic, progressive ERM foveoschisis and LMH may benefit from surgical intervention.

Abstract
PURPOSE To investigate the short-term functional and microstructural outcomes of pars plana vitrectomy (PPV) without gas tamponade in lamellar macular holes (LH). MATERIALS AND METHODS In this prospective case series, LH cases diagnosed by optical coherence tomography (OCT) underwent PPV with epiretinal membrane (ERM) removal and internal limiting membrane peeling without gas tamponade. All patients underwent a complete ophthalmologic examination, including best-corrected visual acuity (BCVA) and OCT imaging preoperatively and 3 months after the surgery. RESULTS Among 22 eyes, 10 degenerative (Deg) LH, 8 tractional (Trac) LH, and 4 mixed-type LH were assessed. After the surgery, anatomical closure occurred in 20 eyes (91%) without any significant difference between LH subgroups. Comparing preoperative and postoperative values, no significant changes was detected regarding BCVA neither totally (P = 0.5) nor in subgroups (P for Deg = 1.0, Trac = 0.71, Mix = 0.18). The overall central foveal thickness was increased significantly after surgery (P < 0.01), but in subgroup analysis, the increase was significant only for Trac LH (P = 0.02). The tractional LH eyes had less ellipsoid zone (EZ) disruptions compared to Deg or mixed subgroups before surgery. There were no changes in EZ integrity before and after the surgery. In regression analysis, no correlation was found between demographic or clinical characteristics and anatomical closure or BCVA improvement postoperatively. CONCLUSION PPV resulted in 91% anatomical closure of all cases of LH but without functional improvement in short-term. Further prospective clinical trials with larger sample size and longer follow-up would be required to confirm the clinical significance of these findings.

Abstract
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 SF6 or C3F8, 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.

Macular Holes: Main Clinical Presentations, Diagnosis, and Therapies. J Ophthalmol 2022; 2022:2270861.

Abstract
Macular holes are a spectrum of retinal diseases that comprehends full-thickness macular holes (FTMHs), refractory/recurrent macular holes, lamellar macular holes (LMHs), myopic macular holes (MMHs), traumatic macular holes, and macular holes secondary to other retinal pathologies or injuries. There are various classifications of the subtypes of macular hole, and only in recent times researchers defined a common nomenclature, especially thanks to the evolution in retinal imaging, offered by new instruments like the swept-source OCT. The proposed therapies for macular holes are different and range from a “wait-and-see” approach to the vitrectomy, with different results in each subtype of macular hole. This narrative review has the purpose to investigate the available evidence in literature to give a summary of the knowledge about these retinal pathologies.

Abstract
BACKGROUND Lamellar macular holes (LMHs) are small, partial-thickness defects of the macula defined by characteristic features on optical coherence tomography (OCT), including a newly recognised type of epiretinal membrane termed 'epiretinal proliferation'. There may be a rationale to recommend surgery for individuals with LMHs, particularly those with functional or anatomical deterioration, or poor baseline vision causing significant disability, to stabilise the LMH and prevent further visual deterioration; however, there is currently no evidence-based consensus. OBJECTIVES To assess the effect of surgical interventions on post-operative visual and anatomical outcomes in people with a confirmed LMH. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE Ovid, Embase Ovid, Scopus SciVerse, ISRCTN registry, US National Institutes of Health Ongoing Trials Register, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We also searched reference lists of included trials to identify other eligible trials which our search strategy may have missed. The date of the search was 20 July 2021. SELECTION CRITERIA We included randomised controlled trials (RCTs) involving participants with a confirmed LMH diagnosis which reported one or more surgical intervention(s), alone or in combination, in at least one arm of the RCT. DATA COLLECTION AND ANALYSIS We used standard methods as expected by Cochrane. Two study authors independently extracted data and assessed the risk of bias for included trials. Trial authors were contacted for further information and clarification. MAIN RESULTS A single RCT was eligible for inclusion. Thirty-six participants were randomised in a 2:1 ratio; 24 were allocated to undergo surgery (pars plana vitrectomy, peeling of the epiretial proliferation followed by fovea-sparing removal of the internal limiting membrane) and 12 (10 following two participant dropouts) to observation. Overall, the certainty of the evidence was low for all outcomes due to selection and detection bias, and the low number of participants enrolled in the study which may affect the accuracy of results and reliability of conclusions. At six-month follow-up, change in vision was better in the surgery group (-0.27 logMAR improvement) than observation (0.02 worsening) (mean difference (MD): -0.29 logMAR, 95% confidence intervals (CI): -0.33 to -0.25). Central retinal thickness increased in the surgery group over 6 months 126 μm increase) compared with observation group (decrease by 11μm) (MD: 137 μm, 95% CI: 125.87 μm to 148.13 μm). Finally, at six-month follow-up, retinal sensitivity was better in the surgery group (3.03 dB increase) compared with the observation group (0.06 dB decrease) (MD: 3.09 dB, 95% CI: 2.07 to 4.11 dB). Vision-related quality of life and metamorphopsia were not reported. No adverse outcomes or complications were reported in the study, however, authors could not provide information on whether any individuals developed deterioration in vision of 0.2 logMAR or worse. AUTHORS' CONCLUSIONS The included single trial demonstrated improvements in visual and anatomical outcome measures for participants with a LMH who underwent surgery compared with observation only. Therefore, we can conclude that participants who undergo surgery may achieve superior post-operative best corrected visual acuity and anatomical outcomes compared with observation only. However, the results of a single and small RCT provides limited evidence to support or refute surgery as an effective management option for LMHs. Future RCTs with a larger number of participants and with fewer methodological limitations and biases are necessary to inform future clinical practice.

Abstract
Purpose To evaluate the visual outcomes of vitrectomy for lamellar macular hole (LMH) and epiretinal membrane (ERM) foveoschisis and to investigate the prognostic factor for postoperative visual acuity. Methods We retrospectively reviewed 15 LMH and 17 ERM foveoschisis eyes that had undergone a standard three-port pars plana vitrectomy with (12 eyes) or without (20 eyes) cataract surgery. Best-corrected visual acuity (BCVA) at postoperative three months and the final visit were compared to the preoperative measurements. We investigated the relationship between BCVA at the final visit and baseline parameters (age, preoperative BCVA, the presence of epiretinal proliferation [EP] and ellipsoid zone [EZ] disruption). The best explanatory variables for the final BCVA were investigated using the corrected Akaike information criterion (AICc) model selection. Results The mean age was 67.2 years. The mean follow-up duration was 30.7 months. Fifteen of 32 examined eyes were diagnosed as LMH and 17 eyes as ERM foveoschisis. Twelve eyes in LMH had EP and 13 eyes showed the disruption of EZ integrity. In total, BCVA significantly improved at 3 months postoperatively (p = 0.0013). A significant improvement was observed in ERM foveoschisis (p = 0.0085) but not in LMH group (p = 0.071). Comparing the BCVA between the baseline and the final visit, significant improvements were observed in total, ERM foveoschisis and LMH group (p<0.001, p<0.001 and p = 0.026, respectively). The optimal model for BCVA at the final visit included preoperative BCVA and the presence of EZ disruption (p<0.001 and p<0.001, respectively). Conclusion Our results suggested that the final BCVA was dependent on preoperative BCVA and the presence of EZ disruption. Surgical indications might be warranted for LMHs with EZ disruption.
