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...

BACKGROUND: To describe the clinical features of acquired progressive esotropia, with a larger angle at distance than near, associated with myopia in young adults. METHODS: Eleven adults (ages ranging from 18 to 37 years) with constant or intermittent horizontal diplopia at distance were recruited. Subjective refraction, ocular alignment, fusional amplitudes and horizontal eye movements were measured at distance and near. RESULTS: Distance esotropia varied from 20 to 60 prism diopters (PD)...

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...

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...

Ranibizumab injection in the treatment of choroidal neovascularization (CNV) secondary to pathologic myopia (PM) with and without a dome-shaped macula (DSM).Prospective observational study.A total of 24 patients (24 eyes) with angiographic evidence of CNV secondary to PM were divided into 2 groups: eyes with a DSM and eyes without DSM. All patients received a baseline intravitreal ranibizumab injection. Additional injections were considered at each follow-up visit. Best-corrected visual acuity (BCVA) and optical coherence tomography were tested monthly through 12 months of follow-up...

OBJECTIVES: To examine the progression pattern of disc and retinal lesions in highly myopic Chinese adolescents over a 10-year period in Singapore. METHODS: This longitudinal study included Chinese participants who showed high myopia (spherical equivalent [SE] worse than or equal to -5 diopters [D]), no history of refractive surgery, and available fundus photographs at both 2006 (baseline) and 2016 (10-year follow-up) visits. Forty-four adolescents (aged 12-16 years at baseline) who were re-examined later at follow-up were included...

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...

Pathologic myopia is a leading cause of visual impairment. Development of myopic choroidal neovascularization (CNV) is one of the most common complications that leads to central vision loss in patients with pathologic myopia. If left untreated, it can cause scarring with expanding macular atrophy leading to irreversible visual loss in a period as short as 5 years. Advancements in multimodal imaging technology have furthered our understanding of the condition; however, further studies are necessary to extend its utility in the diagnosis of myopic CNV...

The aim of this study was to investigate the changes in the elastic modulus and collagen in scleral tissues of different ages. The eyeballs of 1-, 2- and 3-month-old New Zealand white rabbits were obtained to assess three regions of the sclera-anterior, equatorial and posterior. The three regions of the scleral tissues were then separately divided into four groups. The first group was made into scleral strips for elastic modulus measurement using an Instron 5544. The second group was HE stained for observation of the scleral structures...

Myopic choroidal neovascularization (CNV) is one of the most vision-impairing complications in patients with pathologic myopia. It is also one of the most frequently encountered non.age-related macular degeneration causes of CNV and affects young patients in the working age group. Fluorescein angiography (FA) and spectral domain optical coherence tomography (OCT) are generally indicated to confirm the diagnosis of active myopic CNV before initiation of treatment. Without treatment, natural history studies have shown that the vision outcome can be very poor...
