Purpose: To investigate the choroidal thickness (CT) and retinal thickness (RT) in highly myopic tessellated eyes. Methods: In this study, 115 highly myopic eyes were recruited and divided as tessellated fundus ( n = 93) and normal fundus ( n = 22). RT and CT were quantified using optical coherence tomography with enhanced depth imaging (EDI-OCT). Correlation between subfoveal CT (SFCT) and tessellation was analyzed using logistic regression models. Results: Tessellated fundus eyes had thinner CT than did normal fundus eyes, while RT was not statistically different across groups...

PurposeTo assess OCT angiography (OCTA) effectiveness at detecting choroidal neovascularization (CNV) in cases of suspected neovascular age related macular degeneration (nAMD), chronic central serous retinopathy (cCSR) and pathological myopia compared to FFA and how it compares to a multimodal approach (OCT, FFA and ICGA) for detecting the vascular network.MethodsThis was a retrospective observational cohort study of patients who had clinical and/or OCT findings suggestive of CNV, having further investigation with FFA, with or without ICG, and had same day OCTA using the Heidelberg Spectralis OCT2 beta angiography module...

This retrospective consecutive case series aimed to evaluate spectral-domain optical coherence tomography (SD-OCT) for occult macular disease recognition preoperatively in patients scheduled for routine cataract surgery. All patients scheduled for cataract surgery underwent macular SD-OCT. Scans were reviewed for retinal, retinal pigment epithelium and vitreomacular interface abnormalities. For the subgroup analysis, the following information was collected: age; sex; and diabetes, hypertension, myopia, glaucoma, post intra-ocular surgery, endophotocoagulation, retinal vasculopathy and uveitis statuses...

A review of the literature from 2014 to 2016 was conducted, focusing on the results of optical coherence tomography angiography in different chorioretinal diseases. In only 3 years, optical coherence tomography angiography has been shown to be an effective tool for diagnosing choroidal neovascularization complicating age-related macular degeneration, pathologic myopia, and inflammatory conditions. The technique has sometimes been considered superior to conventional multimodal imaging, for example, in choroidal neovascularization associated with chronic central serous chorioretinopathy or multifocal choroiditis...

In our previous study, potential pathological mutations of RetNet genes were detected in 23.8% (71/298) of probands with early-onset high myopia (eoHM), based on whole exome sequencing (WES). The current study aimed to confirm this finding in an additional 325 probands with eoHM and to clarify its specificity by comparison of 195 probands with late-onset high myopia (loHM). Variants in the 234 RetNet genes were selected from whole-exome sequencing data and were filtered using multistep bioinformatics analyses...

REVIEW
Paulus T V M de Jong
Worldwide, and especially in Asia, myopia is a major vision-threatening disorder. From AD 1600 on, to prevent myopia, authors warned against near work without sufficient pauses. There was an abundance of theories about the causes of myopia, the most common one being the necessity of extra convergence on nearby work with thickened extraocular muscles and elevated intraocular pressure. Ocular tenotomies against myopia were in vogue for a while. Axial lengthening of the eye in myopia was mentioned around 1700, but it took 150 years to become accepted as the most prevalent sign of high myopia...

PURPOSE: To analyze the change in refractive error and the axial length of chronic Vogt-Koyanagi-Harada (VKH) disease. METHODS: Medical records of 106 eyes of 54 adult VKH patients were analyzed. The refractive error and the axial length were compared between the baseline (defined as the time point at least 2 weeks after acute stage of VKH) and the final visit. The rate of the eyes with significant myopia progression [defined as refraction change toward myopia > 1 diopter (D)] was examined...

Purpose: Microarray and RNA sequencing studies in the chick model of early optically induced refractive error have implicated thousands of genes, many of which have also been linked to ocular pathologies in humans, including age-related macular degeneration (AMD), choroidal neovascularization, glaucoma, and cataract. These findings highlight the potential relevance of the chick model to understanding both refractive error development and the progression to secondary pathological complications...
