Prognostic value of myopic disk deformation in myopic choroidal neovascularization: A 6-year follow-up study.

Purpose: To evaluate the clinical characteristics of myopic choroidal neovascularization (mCNV) according to peripapillary atrophy (PPA) and optic disk tilt and to explore whether those myopic disk deformations are associated with the prognosis of mCNV. Methods: Patients with subfoveal mCNV who received intravitreal bevacizumab injection and followed for ≥3 years were included. PPA was quantified as area of the ß-zone PPA/disk area ratio (PDR) and optic disk tilt as the tilt ratio (the longest/shortest disk diameter). We compared the clinical characteristics in terms of PDR and tilt ratio and identified the poor prognostic factors using Logistic regression and Cox proportional hazard model. Results: Among 80 eyes of 80 patients, 29 (36.30%) eyes developed macular atrophy during 80.71 ± 34.76 months. PDR and tilt ratio are strongly correlated with each other (P = 0.004). Higher PDR showed significant correlations with longer axial length (P = 0.013), worse baseline and final VA (P = 0.007 and P = 0.047), and thinner subfoveal choroidal thickness (P = 0.039), while higher tilt ratio showed significant correlations only with longer axial length (P = 0.036). High PDR was also an independent risk factor for both macular atrophy (OR = 2.257, P < 0.001) and poor visual outcome (HR = 1.174, P = 0.007), while high disk tilt ratio was not. Conclusion: Subfoveal mCNV with higher ß-zone PPA area/disk area ratio had worse functional and structural outcomes.

Analysis of visual disability in Buenos Aires, Argentina. Pathologic myopia is the leading cause in working age.

This study assessed the causes of visual impairment over a decade in Buenos Aires City. This is a retrospective case series where we reviewed the database of visual disability certificates issued by the Buenos Aires City Ministry of Health between 2009 and 2017. In Argentina, visual disability is defined as a visual acuity = 20/200 in the better eye, or a corresponding visual field of less than 20 degrees in the less impaired eye. The database included the following variables: year of issue, age, gender, and cause of visual disability. Between 2009 and 2017 a total of 7656 subjects were certified as legally blind. The mean age of the sample was 57 ± 21 years and 52.1% were females. The emission was near 700 certificates per year. The age distribution showed that 62.8% of certificates were from patients older than 50 years and that only 6.6% were given to subjects under 20. The leading causes of visual disability in Buenos Aires City were age-related macular degeneration (ARMD) with a rate of 15.5%, degenerative myopia (14.4%), primary open-angle glaucoma (11.3%) and diabetic retinopathy (6.6%). In subjects younger than 50, degenerative myopia was the first cause of visual disability. Interestingly in Argentina, where the prevalence of myopia is low, degenerative myopia is found to be the major cause of visual disability in middle-aged adult subjects. Population and clinical methods to avoid this preventable disease should need to be implemented as a matter of urgency.

Este trabajo estudia las causas de la discapacidad visual durante una década en la Ciudad de Buenos Aires. Se presenta una serie de casos retrospectiva donde se revisó la base de datos de certificados de discapacidad visual emitidos por el Ministerio de Salud de la Ciudad de Buenos Aires entre 2009 y 2017. En Argentina, la discapacidad visual se define como una agudeza visual = 20/200 en el mejor ojo, o un campo visual correspondiente de menos de 20 grados en el ojo menos deteriorado. La base de datos incluyó las siguientes variables: año de emisión, edad, sexo y causa de la discapacidad visual. Entre 2009 y 2017 se certificaron un total de 7656 sujetos con ceguera legal. La edad media de la muestra fue de 57 ± 21 años y el 52.1% fueron mujeres. La distribución por edades mostró que el 62.8% de los certificados fueron dados a pacientes mayores de 50 años y que solo el 6.6% se otorgó a menores de 20 años. Las principales causas de discapacidad visual fueron la degeneración macular asociada a la edad (DMAE) (15.5%), la miopía degenerativa (14.4%), el glaucoma primario de ángulo abierto (11.3%) y la retinopatía diabética (6.6%). En los menores de 50 años, la miopía degenerativa fue la primera causa de discapacidad visual. Resulta interesante que, en Argentina, donde la prevalencia de miopía es baja, la miopía degenerativa sea la principal causa de discapacidad visual en adultos de mediana edad.

Spontaneous Closure of Large Full-Thickness Macular Hole in a Patient with Degenerative Myopia: Case Report

Macular hole is characterized by a full-thickness defect of the retinal layers in the center of the fovea and is an important cause of central vision loss. Spontaneous closure of a macular hole is rare, most often occurring in traumatic and idiopathic macular holes. In this case report, we present a 51-year-old woman with a myopic macular hole that closed spontaneously. The patient had degenerative myopia and a history of clear lens surgery and multiple laser retinopexy procedures due to retinal tear in both eyes. A macular hole was detected in her right eye, but she declined surgery and was followed up. At 66 months after presentation, bridge formation and spontaneous closure of the macular hole were observed. Spontaneous closure is extremely rare in cases of myopic macular hole, but may be seen in patients who are followed for a long time.

Structural profile of dome-shaped macula in degenerative myopia and its association with macular disorders.

BACKGROUND: To evaluate the detailed structural profile of dome-shaped macula and its association with myopic macular complications. METHODS: This retrospective study included 147 eyes of 93 patients who were diagnosed with degenerative myopia. The height of the scleral dome and diameter of the dome base were measured via enhanced depth imaging optical coherence tomography images with 1:1 µm setting. Spherical equivalent and best-corrected visual acuity were compared in eyes with and without dome-shaped macula. In eyes with dome-shaped macula, the height and diameter of the dome were compared in eyes with and without myopic macular complications including choroidal neovascularization, myopic foveoschisis, and macular hole. RESULTS: Dome-shaped macula was noted in 60 eyes (40.8%) of 42 patients. The mean height of the dome in the eyes with dome-shaped macula was 126.5 ± 69.4 µm (53 to 345 µm) and the mean diameter of the dome base was 2862.1 ± 794.9 µm (1567 µm to 4886 µm). In comparing eyes with and without dome-shaped macula, eyes with dome-shaped macula had higher myopia (- 13.7 diopters vs - 12.1 diopters, P = 0.022). There was no difference in visual acuity in eyes with or without dome-shaped macula (P = 0.132). The height and diameter of the dome in eyes with and without myopic foveoschisis were 78.6 ± 20.6 µm and 134.9 ± 71.6 µm, 2499.2 ± 303.1 µm and 2969.3 ± 645.7 µm, respectively (P = 0.009 and P = 0.017). However, the height and diameter of the dome were not related to the incidence of a macular hole (P = 0.324 and P = 0.605) and choroidal neovascularization (P = 0.835 and P = 0.905). CONCLUSIONS: The prevalence of dome-shaped macula was about 40% in the eyes with degenerative myopia. Although dome-shaped macula was associated with higher degrees of myopia, a prominent dome seemed to be protective against myopic foveoschisis.

Long-term Outcomes of Vitrectomy Used to Treat Myopic Traction Maculopathy

PURPOSE: We investigated the long-term outcomes of vitrectomy with internal limiting membrane (ILM) peeling as treatment for myopic traction maculopathy (MTM).METHODS: The medical records of patients who underwent vitrectomy to treat MTM were retrospectively evaluated. We excluded patients who exhibited macular holes (MHs) or retinal detachment at the time of primary surgery. The best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analyzed preoperatively, at 3, 6, 12, and 24 months after surgery, and at the final visit. Complications including retinal detachment or an MH were noted during follow-up.RESULTS: Twenty-three eyes of 22 patients were enrolled. At the time of primary surgery, the mean patient age was 64.4 ± 11.1 years and the baseline mean logMAR BCVA and CFT, 0.67 ± 0.50 and 431.8 ± 159.5 µm, respectively. The mean follow-up period was 53.7 ± 19.3 months. The mean logMAR BCVAs at 3, 6, 12, and 24 months postoperatively and at the final visit were 0.42 ± 0.39 (p = 0.001), 0.41 ± 0.38 (p = 0.001), 0.39 ± 0.40 (p < 0.001), 0.42 ± 0.43 (p < 0.001), and 0.51 ± 0.47 (p = 0.016), respectively, thus significantly better than the baseline value. The mean CFT at 3, 6, 12, and 24 months postoperatively and at the final visit were 244.6 ± 72.3, 210.5 ± 79.1, 209.6 ± 91.6, 219.8 ± 93.9, and 217.7 ± 81.3 µm, respectively, thus significantly less than baseline (all p < 0.001). MTM resolved in 18 eyes (78.3%) after primary surgery, without any complication, and remained stable to the final visit.CONCLUSIONS: Vitrectomy with ILM peeling afforded favorable long-term efficacy and safety in MTM patients.

Long-term Outcomes of Macular Hole Retinal Detachment in Highly Myopic Eyes after Surgical Reattachment.

PURPOSE: To evaluate visual acuity changes over 3 years following surgical reattachment of macular hole retinal detachment (MHRD) developed in high myopia. METHODS: A retrospective analysis was performed using the medical records of patients with highly myopic eyes who underwent pars plana vitrectomy with internal limiting membrane peeling or the internal limiting membrane flap technique for MHRD. Changes in best-corrected visual acuity (BCVA) were measured at baseline, 6 months, 1 year, 2 years, and 3 years. RESULTS: Of the 22 eyes analyzed, macular hole was closed in 13 and unclosed in nine. BCVA significantly improved from 1.61 ± 0.39 logarithm of the minimum angle of resolution (logMAR) at baseline to 1.17 ± 0.43 logMAR at 6 months and 1.33 ± 0.48 logMAR at 2 years after MHRD surgery. At 3 years, BCVA significantly decreased compared with that at 6 months, and visual improvement from baseline was not significant. BCVA and proportion of vision loss ≥0.3 logMAR were not different between the closed and unclosed macular hole groups. CONCLUSIONS: Visual improvement after surgical reattachment of MHRD in high myopia was not maintained, and favorable macular hole closure effects were not observed at 3-year follow-up.

Macular hole retinal detachment after intravitreal Conbercept injection for the treatment of choroidal neovascularization secondary to degenerative myopia: a case report.

BACKGROUND: We report a case of macular hole (MH) formation and retinal detachment after intravitreal conbercept injection for the treatment of choroidal neovascularization (CNV) secondary to degenerative myopia. CASE PRESENTATION: A 60-year-old woman presented with blurred vision in her left eye was diagnosed as CNV secondary to degenerative myopia. Intravitreal injection of conbercept, an anti -vascular endothelial growth factor (VEGF) agent, was uneventfully performed in the left eye. Unfortunately, a full thickness MH and retinal detachment was found three weeks postoperatively by ophthalmoscopy and spectral-domain optical coherence tomography. Vitrectomy, internal limiting membrane peeling and silicone oil tamponade were then performed, and macular retina was reattached soon after surgery. However, MH still kept open during three months' follow-up. CONCLUSION: MH is a quite rare complication of intravitreal anti- VEGF agent injection, tangential contraction secondary to CNV shrinkage and regression caused by anti-VEGF agent is proposed to be the major pathogenesis of MH formation.

Vitrectomy in high myopia: a narrative review.

Pathologic myopia is associated with degenerative changes of the globe, especially at the posterior pole. Eyes affected by pathologic myopia have higher odds to undergo posterior segment surgery and, in those eyes, vitreoretinal surgery is challenging. Many practical tips and tricks can make the surgical procedures simpler, significantly preventing sight-threatening intra- and post-operative complications. Moreover, novel surgical techniques and technological advancements (i.e. ad-hoc instrumentation, minimally invasive vitreoretinal surgery, filters, dye staining, intraoperative optical coherence tomography and 3-dimensional surgery) may play role in highly myopic eyes. The aim of the present work is to review practical tips and tricks, novel surgical techniques and technological advancements.

Retinal Break Adjacent to the Optic Disc Causing Retinal Detachment in a Pathological Myopia

Retinal detachment is one of the common complications of pathological myopia due to presence of retinal break. However, retinal break commonly occurs in the peripheral retina. This case report illustrates the rare incidence of retinal break adjacent to the optic disc, highlights the possible causes of poor visual outcome following surgical repair as well as the possible measures to treat the complications.

The Choroid and Optical Coherence Tomography.

The choroid is the most vascular tissue in the eye and it plays an important role in the pathophysiology of various common chorioretinal diseases such as central serous retinopathy, age-related macular degeneration and degenerative myopia. Quantitative assessment of the choroid has been quite challenging with traditional imaging modalities such as indocyanine green angiography and ultrasonography due to limited resolution and repeatability. With the advent of optical coherence tomography (OCT) technology, detailed visualization of the choroid in vivo is now possible. Measurements of choroidal thickness have also enabled new directions in research to study normal and pathological processes within the choroid. The aim of the present study is to review the current literature on choroidal imaging using OCT.

Tratamiento de la neovascularización coroidea miópica / Treatment of myopic choroidal neovascularization

Se realizó una revisión sobre el tratamiento de la neovascularización coroidea en la miopía degenerativa. Se consultaron fundamentalmente artículos científicos de revistas publicados e indexados en las bases de datos PubMED y Cochrane, así como textos básicos que abordan este tema. No se encontraron certezas del beneficio de la fotocoagulación con láser de las lesiones neovasculares en esta entidad, mientras que la terapia fotodinámica parece brindar estabilidad de la lesión y mejoría visual, al menos a los 3 años de seguimiento. El uso de antiangiogénicos intravítreos tiene los mejores resultados en la actualidad respecto a la inactivación de la lesión y la recuperación visual pero no hay ensayos clínicos controlados que avalen su beneficio a largo plazo. Otras opciones de tratamiento se encuentran en investigación y desarrollo. No se ha concebido el protocolo ideal para tratar las membranas neovasculares miópicas

A literature review on the treatment of the choroidal neovascularization in the degenerative myopia was made. Published scientific articles of journals indexed in Pubmed and Cochrane databases, as well as basic texts that deal with this topic. No evidences of the benefits of the laser photocoagulation for neovascular lesions were found, whereas the photodynamic therapy seems to offer stability of the lesion and visual improvement after three years of follow-up. The use of intravitreous antiangiogenic drugs has currently achieved the best results in terms of lesion inactivation and visual recovery, but there are no controlled clinical trials that support their long-term benefits. Other treatment options are under research and development. The ideal protocol of treatment of neovascular myopic membranes has not yet been devised
