RESUMEN
PURPOSE: To describe the retinal and vitreous changes in eyes showing myopic macular schisis (MMS) improvement when vitrectomy was not performed and identify triggering factors. DESIGN: Retrospective observational study. SUBJECTS: Patients with nonoperated MMS. METHODS: The records of patients with MMS who were followed without performing surgery for >6 months were retrospectively reviewed, and the eyes showing an anatomic improvement were included. Myopic macular schisis evolution was analyzed quantitatively (central foveal thickness [CFT], parafoveal thickness, maximum height) and qualitatively (presence/absence of foveal detachment, lamellar hole, epiretinal membrane, choroidal neovascularization, inner and outer retinoschisis, vitreous status) at baseline and at the final visit. An anatomic improvement was defined as a decrease in CFT by ≥50 µm. MAIN OUTCOME MEASURES: The rate of anatomic improvement of MMS without performing vitrectomy and the morphological changes observed in these cases. RESULTS: In a cohort of 74 nonoperated eyes with MMS, MMS improved in 14 eyes (19%) after a mean follow-up of 55 ± 38 months (range, 8-138). In these improved cases, the mean decrease in CFT was 153 ± 166 µm (range, 24-635; P = 0.005) and a complete resolution of MMS was observed in 9 eyes (64%). In 9 eyes (64%), the improvement was associated with visible vitreous changes in the macular area on the OCT scans. The mean visual acuity, which was already good at baseline (20/50, 0.4 ± 0.2 logarithm of the minimum angle of resolution), increased at the last visit (20/40, 0.3 ± 0.3 logarithm of the minimum angle of resolution) but without reaching significance. CONCLUSIONS: This long-term follow-up analysis showed that almost 20% of MMS in eyes without indication for surgery could improve over time. In most cases, the improvement was associated with an apparent resolution of vitreous tensions.

RESUMEN
OBJECTIVE: This study aimed to evaluate and explore the efficacy of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling and gas tamponade in treating myopic foveoschisis (MF) through a meta-analysis. METHODS: Systematic searches were conducted on the PubMed, Web of Science and National Library of Medicine (NLM) English-language databases and the China National Knowledge Infrastructure (CNKI) and Wanfang Chinese-language databases. The primary outcome measures were postoperative best-corrected visual acuity (BCVA) and central foveal thickness (CFT), with the secondary outcome being the postoperative complication rate. Data analysis was performed using RevMan5.3 software. RESULTS: A total of 10 studies involving 234 eyes were included. The meta-analysis results showed the following: (1) The average postoperative BCVA improved compared with preoperative levels, with an average improvement in the logarithm of the minimum angle of resolution of 0.40, a statistically significant difference (95% CI: -0.44, - 0.20, p < 0.001); (2) the rate of postoperative BCVA improvement was 77% (95% CI: 65%, 90%, p < 0.001); (3) the postoperative CFT significantly decreased by an average of 385.92 µm, a statistically significant difference (95% CI: -437.85, - 333.98, p < 0.001); (4) the postoperative macular retinal complete reattachment rate was 90% (95% CI: 83%, 97%, p < 0.001); (5) the most common postoperative complication was a cataract, with an incidence of 55.9%. CONCLUSION: Using PPV combined with ILM peeling and gas tamponade to treat MF is reliable.

BACKGROUND: Presently, the global prevalence of myopia and high myopia reaches approximately 1.95 billion and 277 million individuals, respectively. Projections suggest that by 2050, the number of people with myopia may rise to 4.758 billion and those with high myopia to 938 million. In highly myopic eyes, the occurrence of MF is reported to be as high as 8-33%. SUMMARY: This review comprehensively addresses the classification, pathogenesis, natural progression, concomitant pathologies, and therapeutic strategies for macular foveoschisis in highly myopic patients. KEY MESSAGES: In recent years, macular foveoschisis has emerged as a prevalent complication in individuals with high myopia, primarily resulting from the combination of inward traction by vitreoretinal adhesions and outward traction exerted by posterior scleral staphyloma on the retina. While some maintain partial visual stability over an extended period, others may progress to macular holes or even retinal detachment. For highly myopic patients with macular foveoschisis, the mainstay procedures are vitrectomy, macular buckle, and posterior scleral reinforcement. However, there is controversy about whether to perform inner limiting membrane peeling and gas filling.

A 61-year-old Malaysian Chinese man who has high myopia complained of both eye floaters. Spectral-domain optical coherence tomography (SD-OCT) of the macula showed bilateral posterior staphyloma with right eye (RE) foveoschisis without macula detachment, which had been stable for a seven-year follow-up. When bilateral YAG laser vitreolysis could not alleviate his symptoms, he underwent pars plana vitrectomy with the inducement of posterior vitreous detachment, first in the left eye, followed by the RE one month later. The best-corrected visual acuity for both eyes was 6/6, N5 two months postoperatively, and he was asymptomatic for floaters. However, six months postoperatively, he complained of metamorphopsia and worsening RE vision. Repeat OCT showed worsening of the foveoschisis bilaterally with left foveal detachment. The patient had to undergo a repeat vitrectomy with peeling of the internal limiting membrane (ILM) in bilateral eyes, which successfully restored his foveal architecture and alleviated his symptoms. This article highlights theimportance of preoperative OCT assessment of the fovea in patients undergoing vitrectomy for floaters, as staining and complete removal of posterior hyaloid with ILM peeling during vitrectomy may mitigate the progression of foveoschisis after core vitrectomy for floaters in myopic patients.
RESUMEN
AIM: To compare the efficacy of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) and silicone oil or sterile air tamponade for the treatment of myopic foveoschisis (MF) in highly myopic eyes. METHODS: This retrospective study included 48 myopic eyes of 40 patients with MF and axial lengths (ALs) ranging from 26-32 mm treated between January 2020 and January 2022. All patients were underwent PPV combined with ILM peeling followed by sterile air or silicone oil tamponade and followed up at least 12mo. Based on the features on spectral-domain optical coherence tomography (SD-OCT), the eyes were divided into the MF-only group (Group A, n=15 eyes), MF with central foveal detachment group (Group B, n=20 eyes), and MF with lamellar macular hole group (Group C, n=13 eyes). According to AL, eyes were further divided into three groups: Group D (26.01-28.00 mm, n=12 eyes), Group E (28.01-30.00 mm, n=26 eyes), and Group F (30.01-32.00 mm, n=10 eyes). The best-corrected visual acuity (BCVA), central foveal thickness (CFT), and complications were recorded. RESULTS: The patients included 16 males and 24 females with the mean age of 56±9.82y. The BCVA and CFT improved in all groups after surgery (P<0.01), while there was no significant difference of the CFT in Group A, B, and C postoperatively (P>0.05). The intergroup differences of BCVA and CFT postoperatively were statistically significant in Group D, E, and F. Twenty eyes were injected with sterile air, and 28 eyes were injected with silicone oil for tamponade based on the AL. However, there was no statistically significant difference among Groups D, E, and F in terms of the results of sterile air or silicone oil tamponade. The mean recovery time was 5.9mo for MF patients subjected to silicone oil tamponade and 7.7mo for patients subjected to sterile air tamponade, and the difference was not statistically significant. CONCLUSION: PPV and ILM peeling combined with silicone oil or sterile air tamponade can achieve good results for MF in highly myopic eyes with ALs≤32 mm.
RESUMEN
Purpose: To characterize the change in visual acuity (VA) in eyes treated with vitrectomy using the 2020 international consensus-based optical coherence tomography (OCT) definition of lamellar macular hole (LMH), macular pseudohole (MPH), and epiretinal membrane with foveoschisis (ERMF). Methods: A retrospective chart review was performed from 2000 to 2022 of patients who had vitrectomy for symptomatic decreased VA from LMH, MPH, or ERMF performed by the same surgeon at a community hospital. Preoperative spectral domain (SD-OCT) was reviewed to classify patients using the consensus guidelines. Primary outcomes were the mean change in best-corrected VA at 3 months, 1 year, and the final postoperative examination. Results: Fifty-one patients were included, 30 with LMH, 14 with MPH, and 7 with ERMF. The VA was 20/63 at baseline, 20/62 (P = .79) 3 months postoperatively, 20/40 (P = .003) at 1 year, and 20/52 (P = .10) at the final examination for LMH; 20/64, 20/50 (P = .16), 20/40 (P = .040), and 20/40 (P = .02), respectively, for MPH; and 20/53, 20/50 (P = .42), 20/30 (P = .03), and 20/38 (P = .04), respectively, for ERMF. Subgroup analysis showed that eyes with LMH without ellipsoid zone (EZ) disruption on SD-OCT improved from 20/57 at baseline to 20/39 (P = .01) at the final examination. Conclusions: There was no significant improvement in VA at the final postvitrectomy examination in eyes with LMH, while there was significant improvement in eyes with MPH and ERMF. This supports surgery in selected eyes with MPH and ERMF but possibly not in eyes with LMH, unless OCT shows no EZ disruption.
RESUMEN
BACKGROUND: Myopic traction maculopathy (MTM) is a complication of pathological myopia and encompasses various pathological conditions caused by tractional changes in the eye. These changes include retinoschisis, foveal retinal detachment, and lamellar or full-thickness macular holes (FTMHs). This meta-analysis evaluated the safety and efficacy of novel surgical for treating MTM. METHODS: To compare the outcomes of different surgical approaches for MTM, multiple databases, including Web of Science, PubMed, Scopus, ClinicalTrials.gov, the Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Embase, and the Meta-Register of Controlled Trials, were comprehensively searched. The meta-analysis was performed using RevMan 5.1. RESULTS: Nine comparative studies involving 350 eyes were included in this meta-analysis. There were significant differences between fovea-sparing internal limiting membrane peeling (FSIP) and standard internal limiting membrane peeling (ILMP). Preoperative best-corrected visual acuity BCVA (standard mean difference (SMD): -0.10, 95% CI: -0.32 to 0.12) and central foveal thickness CFT (SMD: 0.05, 95% CI: -0.22 to 0.33) were not significantly different (p = 0.39 and p = 0.71, respectively). However, the postoperative BCVA improved significantly (SMD = - 0.47, 95% CI: - 0.80, - 0.14, p = 0.006) in the FSIP group compared to the standard ILMP group. Postoperative CFT did not differ significantly between the two groups (p = 0.62). The FSIP group had a greater anatomical success rate than the other groups, although the difference was not statistically significant (p = 0.26). The incidence of postoperative macular hole formation was significantly lower (OR = 0.19, 95% CI = 0.07-0.54; p = 0.05) in the FSIP group than in the standard ILMP group. The unique characteristics of highly myopic eyes, such as increased axial length and structural changes, may have contributed to the greater incidence of FTMH in the ILMP group. CONCLUSION: Based on the findings of this meta-analysis, FSIP is the initial surgical approach for early-stage MTM and has shown promising outcomes. However, to establish the safest and most efficient surgical technique for treating different MTM stages, further comparative studies, specifically those focusing on ILMP and FSIP, are necessary. TRIAL REGISTRATION: Retrospectively registered.

INTRODUCTION: The aim of this study was to evaluate the clinical characteristics and surgical outcomes of the epiretinal membrane foveoschisis (ERM-FS) with different morphological types. METHODS: This retrospective observational study reviewed 44 consecutive ERM-FS patients who underwent ERM surgery. According to the optical coherence tomography images, ERM-FS was classified into three groups: group A, FS crossed the fovea with the foveola elevated; group B, FS located at the foveal edges with a near-normal central foveal point thickness; and group C, FS with undermined foveal edges with a near-normal central foveal point thickness. RESULTS: There were 10 eyes in group A, 20 eyes in group B, and 14 eyes in group C. Preoperatively, eyes in group A had the best best-corrected visual acuity (BCVA), the thickest central foveal point thickness, and the highest ellipsoid zone (EZ) intact rate among the three groups. After surgery, a resolution of foveoschisis was observed in 40.0%, 45.0%, and 50.0% of the eyes in group A, group B, and group C (p = 0.928), respectively. BCVA was significantly improved postoperatively. Although there was no significant difference in BCVA among the three groups at 1 month postoperatively, BCVA of group A was the best at 4 and 10 months. Correlation analysis indicated that the type of ERM-FS, baseline BCVA, central foveal point thickness, and postoperative EZ continuity (all p < 0.05) were important factors for the final BCVA. CONCLUSIONS: The damage to the retinal structure and visual function was milder in group A ERM-FS. Our study emphasized the necessity of OCT-based subtyping in patients with ERM-FS.

INTRODUCTION: The aim of this study was to describe differences in the vitreomacular interface (VMI) in idiopathic epiretinal membrane (ERM) foveoschisis compared to macular pseudohole (MPH) and lamellar macular hole (LMH). METHODS: We analysed surgically excised epiretinal material and internal limiting membrane (ILM) specimens obtained from 16 eyes of 16 patients with ERM foveoschisis (6 eyes), MPH (5 eyes), and LMH (5 eyes) during standard pars plana vitrectomy (PPV) with membrane peeling. The three entities were classified according to the newly introduced optical coherence tomography (OCT) terminology. Transmission electron microscopy (TEM) was used to describe the ultrastructural features. RESULTS: We found fibrocellular epiretinal tissues in all samples analysed. However, the cell and collagen composition of the VMI differed between groups. Eyes with ERM foveoschisis were characterized by a higher number of cells, multilayered membranes, and thick strands of vitreous collagen embedding the major cell types of myofibroblasts compared to MPH. Eyes with MPH also showed a predominance of myofibroblasts, but these were located directly on the ILM with no collagen between the cells and the ILM. Eyes with LMH showed a thick, multilayered epiretinal proliferation consisting mainly of non-tractional glial cells, corresponding to hypodense epiretinal proliferation on OCT. Eyes with ERM foveoschisis and MPH were more likely to have incomplete PVD compared to LMH in terms of posterior hyaloid status. DISCUSSION/CONCLUSION: Tractional ERMs in eyes with ERM foveoschisis and MPH differ in their ultrastructure. The main difference is in the amount and topographical distribution of vitreous collagen. However, the epiretinal cell types are predominantly myofibroblasts in both entities. This highlights the importance of distinguishing ERM foveoschisis from both MPH and LMH in terms of pathogenesis and surgical peeling procedures.

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: Optical coherence tomography 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.

RESUMEN
Stellate foveomacular retinoschisis is commonly associated with congenital X-linked retinoschisis, which is almost exclusively seen bilaterally in males. In the absence of a family history of retinoschisis and other related conditions, the term stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) is used. SNIFR constitutes a rather rare diagnosis and is usually observed unilaterally in myopic females. Within this context, we report a case of a non-myopic female patient with bilateral SNIFR detected with optical coherence tomography (OCT).
RESUMEN
Purpose: Myopic choroidal neovascularization (CNV) and myopic traction maculopathy are major complications of pathologic myopia, and myopic foveoschisis (MF) is one of several symptoms that can be included under the general term "myopic traction maculopathy"; however, only a few cases will have MF around the myopic CNV. We report three cases with MF around myopic CNV that followed different clinical courses observed using swept-source optical coherence tomography. Observations: Case 1 was a 69-year-old woman with an axial length of 29.71 mm, myopic CNV, and MF in the left eye. One month after intravitreal injection of ranibizumab (IVR), a macular retinal detachment (RD) expanded. Vitrectomy and gas tamponade were performed during month 2; the macular RD and MF resolved gradually thereafter. Case 2 was a 54-year-old man with an axial length of 30.59 mm, myopic CNV, and MF in the right eye; after IVR, a macular RD developed and gradually expanded until month 4; the RD and MF resolved spontaneously and resolved during month 8. Case 3 was a 66-year-old woman with an axial length of 28.63 mm, myopic CNV, and MF in the left eye. A macular RD expanded 1 month after a previous vitrectomy for MF; after intravitreal injection of aflibercept, the macular RD and MF resolved gradually in month 12. In all cases, the CNV was accompanied by subretinal fluid, and two of the three cases had outer lamellar holes. Conclusion and Importance: The MF around the myopic CNV may lead to exacerbated MF and RD during follow-up, and the subretinal fluid caused by the CNV might facilitate MF progression. Since this condition is rare, further investigation of this entity is needed to determine appropriate management.
RESUMEN
Epiretinal membrane (ERM) foveoschisis is a recently proposed clinical entity. The purpose of this study was to compare the clinical characteristics and surgical outcomes of eyes with ERM foveoschisis to those of typical ERM. The medical records of all patients with ERM-related disorders examined between 2011 and 2020 were reviewed. ERM foveoschisis was defined by the clinical criteria proposed by an international panel of experts on ERMs. The background factors, clinical characteristics, and surgical outcomes of ERM foveoschisis were compared to those of typical ERM. Forty eyes with ERM foveoschisis were compared to 333 eyes with typical ERM. The percentage of women was significantly higher in the ERM foveoschisis group (92.5%) than in the typical ERM group (48.9%, p < 0.001). The central macular thickness (CMT) was significantly thinner in the ERM foveoschisis group (340 ± 110 µm) than in the typical ERM groups (476 ± 111 µm, p < 0.01). The degree of improvement in the best-corrected visual acuity (BCVA) three months after the surgery did not differ between the two groups (p = 0.59). These results suggest that the ERM foveoschisis is more likely to occur in women and that the prognosis after surgery is comparable to typical ERM.
RESUMEN
Purpose: To investigate the involvement of retinal traction in the pathogenesis of lamellar macular hole (LMH) and related diseases based on OCT-based consensus definition. Design: Retrospective, observational study. Participants: Seventy-two eyes with LMH, epiretinal membrane foveoschisis (ERM-FS), or macular pseudohole (MPH). Methods: To quantitatively evaluate the involvement and strength of retinal traction in their pathogenesis, retinal folds were visualized with en face OCT imaging, and the maximum depth of the parafoveal retinal folds (MDRF) was measured. Metamorphopsia was quantified by measuring the minimum visual angle of dotted lines needed to cause it to disappear using M-CHARTS (Inami). Main Outcome Measures: Maximum depth of retinal folds and M-CHARTS scores. Results: Of the 72 eyes, 26 were classified as having LMH, 25 as having ERM-FS, and 21 as having MPH. Parafoveal retinal folds were observed in 7 (26.9%) eyes with LMH, 25 (100%) with ERM-FS, and 21 (100%) with MPH. The MDRF (7.5 ± 17.6 µm) was significantly smaller in LMH than in ERM-FS (86.3 ± 31.4 µm) and MPH (74.5 ± 24.6 µm) (both P < 0.001), whereas no significant difference in MDRF between MPH and ERM-FS was observed (P = 0.43). A significant positive correlation between MDRF and M-CHARTS scores was observed in ERM-FS and MPH (P = 0.008 and 0.040, respectively) but not in LMH (P = 0.073). Conclusions: Retinal traction was significantly weaker in the LMH group than in the ERM-FS and MPH groups. The MDRF was significantly associated with the degree of metamorphopsia in the ERM-FS and MPH groups. These results provide insights into the diseases' pathophysiology and treatment strategy.
RESUMEN
Background: This study aimed to report a case of outer lamellar macular hole and outer retinal detachment within myopic foveoschisis (MF) post-cataract surgery. Case presentation: An elderly female patient with bilateral high myopia and pre-existing myopic foveoschisis underwent uncomplicated sequential cataract surgeries 2 weeks apart. She was able to achieve a satisfactory visual outcome for her left eye with stable myopic foveoschisis and visual acuity of 6/7.5, near vision N6. However, her right eye vision remained poor postoperatively, with a visual acuity of 6/60. Macular optical coherence tomography (OCT) revealed a new right eye outer lamellar macular hole (OLMH) and outer retinal detachment (ORD) within pre-existing myopic foveoschisis. Her vision remained poor after 3 weeks of conservative management, and she was offered vitreoretinal surgical intervention with pars plana vitrectomy, internal limiting membrane peeling, and gas tamponade. However, she refused surgical intervention, and her right vision remained stable at 6/60 over 3 months of follow-up. Conclusion: Outer lamellar macular hole and outer retinal detachment within myopic foveoschisis can occur soon after cataract surgery, which may be related to the progression of associated vitreomacular traction, and have a poor visual outcome if left untreated. Patients with high myopia should be informed of these complications as part of pre-operative counseling.
RESUMEN
Purpose: To investigate morpho-functional changes after surgical treatment for ERM foveoschisis or lamellar macular hole (LMH), and to evaluate whether the two entities are associated with different healing processes and long-term outcomes. Design: Retrospective interventional case series. Methods: A total of 56 eyes, treated for lamellar macular defects and followed up for 24 months, were enrolled. The eyes were divided into two groups: 34 with ERM foveoschisis and 22 with LMH. Changes in the following features were evaluated and compared between the two groups: best-corrected visual acuity (BCVA), external limiting membrane (ELM) and ellipsoid zone (EZ) defects, central foveal thickness (CFT), and autofluorescence (FAF) diameter and area. Results: After surgery, progressive BCVA improvement was observed with no significant difference between the two groups (p-value: 0.06). An increased number of eyes with intact outer-retinal layers was found both in the ERM foveoschisis and LMH groups. FAF diameter and area decreased significantly throughout the FU with no significant difference between the two groups (p-value: 0.2). Conclusion: In the present study, significant functional and microstructural improvements were observed after surgery for both ERM foveoschisis and LMH, demonstrating considerable repair potential in both types of lamellar defects. These findings question the true "degenerative" nature of LMH.
RESUMEN
Ornithine aminotransferase (OAT) deficiency is an autosomal recessive disease characterized by elevated serum ornithine levels caused by mutations in genes encoding for ornithine aminotransferase, a vitamin B6-dependent mitochondrial matrix enzyme. Gyrate atrophy (GA) is characteristic findings in OAT that characterized by sharply demarcated circular, pigmentary, brain-like areas of chorioretinal atrophy in the peripheral retina. This case report presents rare assosiation between OAT and GA and describes the characteristic imaging findings of this unique, not fully understood clinical entity. The coexistence of GA and foveoschisis is extremely rare in OAT deficiency. We report a case of foveoschisis in a patient with OAT, and we will discuss the possible mechanisms that lead to it. A 24-year-old male patient presented with complaints of decreased vision and nictalopia for 1 year. The patient, who was diagnosed with oat 6 years ago, had typical gyrate atrophy in his Fundus floresein angiography and foveoschisis in his Optical coherence tomography. He was diagnosed with gyrate atrophy and foveoschisis. GA caused by OAT deficiency may present with macular involvement in the form of foveoschisis causing central visual impairment. Ophthalmologists should not ignore detailed fundus examination in children and young patients with visual impairment and should be aware of possible systemic diseases.

Purpose: To report a case of a rare disease entity Posterior Microphthalmos Pigmentary Retinopathy Syndrome (PMPRS) in a 47-year-old female with a brief review of literature. Case Report: A 47-year-old woman presented with a history of defective vision with an associated difficulty in night vision. Clinical workup was done, which included a thorough ocular examination showing diffuse pigmentary mottling of fundus, ocular biometry showing short axial length with normal anterior segment dimensions, electroretinography showing extinguished response, optical coherence tomography showing foveoschisis, and ultrasonography showing thickened sclera-choroidal complex. Findings were consistent with those reported by other authors with PMPRS. Conclusion: Posterior microphthalmia with or without other ocular and systemic associations should be suspected in cases with high hyperopia. It is mandatory to carefully examine the patient at presentation and close follow-ups are needed to maintain visual function.
RESUMEN
PURPOSE: To evaluate the incidence, pathogenesis, risk factors, and treatment outcomes of postoperative macular hole (MH) after pars plana vitrectomy (PPV) for myopic traction maculopathy (MTM). DESIGN: Multicenter, interventional, retrospective case series. SUBJECTS: Consecutive eyes that underwent PPV for MTM with a minimum 6-month follow-up. METHODS: We investigated the characteristics and treatment outcomes of postoperative MH after MTM surgery. MAIN OUTCOME MEASURES: Incidence, risk factors, and anatomic and visual outcomes of postoperative MH. RESULTS: We included 207 eyes (207 patients) with a mean follow-up of 25.9 months. During follow-up, 24 (11.6%) eyes developed MH (10 with concurrent MH retinal detachment); 15 eyes within 30 days (early), 4 eyes between 31 and 180 days (intermediate), and 5 eyes after 180 days (late). Logistic regression analysis revealed male gender (odds ratio [OR], 2.917; 95% confidence interval [CI], 1.198-7.100; P = 0.018), thinner preoperative choroidal thickness (OR, 0.988; 95% CI, 0.976-1.000; P = 0.048), and use of indocyanine green for internal limiting membrane peeling (OR, 2.960; 95% CI, 1.172-7.476; P = 0.022) as significant risk factors for postoperative MH. Internal limiting membrane peeling with a fovea-sparing technique tended to protect against postoperative MH, but it was not statistically significant (P = 0.096), because 1 eye still developed MH. Postoperative MHs were treated by observation (6 eyes), in-office octafluoropropane (C3F8) gas injection (7 eyes), or PPV (11 eyes). Macular hole closure was achieved in 20 eyes (83%). The hole closure rate was 67% (4/6 eyes) after observation, 71% (5/7 eyes) after C3F8 gas injection, and 91% (10/11 eyes) after PPV. However, visual outcomes were significantly worse for eyes with postoperative MH than those without (0.38 ± 0.43 vs. 0.68 ± 0.46; P = 0.002). CONCLUSIONS: Postoperative MH may occur in 11.6% of patients with MTM at any time after surgery. Retreatment resulted in relatively favorable anatomic closure but unfavorable visual outcomes.

To present a case of anatomical success and visual improvement after the treatment of a long-standing foveal retinal detachment in a staphylomatous myopic eye with foveoschisis and macular hole. A 60-year-old woman with high myopia presented with foveoschisis and a lamellar macular hole in her right eye. After 2 years of follow-up without deterioration, her eye developed a full-thickness macular hole and a foveal retinal detachment which caused a severe reduction in visual acuity. However, the patient had no surgical treatment for her condition at that time. Vitrectomy was performed 2 years after the retinal detachment formation. Regardless of the longstanding detachment, anatomical success, and visual improvement were evident after the surgery. Despite a 2-year longstanding foveal detachment on a highly myopic eye with foveoschisis and macular hole, surgical repair could still be satisfactory.
