Purpose: To examine the retinal vasculature in patients with obstructive sleep apnea-hypopnea syndrome (OSAS) and to determine the correlation between retinal vascularity and the severity of OSAS. Design: Prospective, cross-sectional study. Methods: Sixty-nine consecutive subjects who underwent polysomnography were enrolled. Patients were divided into three groups according to the severity of OSAS, which was defined using the apnea-hypopnea index (AHI) as normal-to-mild (AHI <15), moderate (≥15 to <30), or severe (≥30)...

BACKGROUND: To report the clinical, electrophysiological and the anatomical findings in a patient with Kearns-Sayre syndrome (KSS). CASE PRESENTATION: We present the case of a 55-year-old female with KSS, who developed systemic features and ocular manifestations as ophthalmoplegia and retinal dysfunction, that were corroborated by electrophysiological test and High Definition Spectral Domain Optical Coherence Tomography (HD SD OCT) and OCT-Angiography (OCT-A). CONCLUSION: We report a patient with KSS, accompanied by some alterations of the RPE and photoreceptors observed in the external HD SD OCT and OCT-A...

Retinal vasculitis presents with inflammation involving the retinal vasculature as an isolated disease or in combination with other ocular or systemic conditions. This entity may be associated with a wide variety of clinical manifestations such as vascular sheathing, cotton-wool spots, retinal ischemia, and neovascularization. Often, retinal vasculitis and its complications lead to diagnostic challenges in identifying the exact etiology of the inflammation. Ancillary investigations such as fundus photography, fluorescein angiography, and more recently, adaptive optics imaging and optical coherence tomography angiography, may provide valuable information that help in establishing the exact diagnosis and initiation of appropriate therapy...

A 15-year-old male patient with corneal hydrops and a giant intrastromal cleft (pseudocyst) successfully received medical treatment with topical prednisolone, hypertonic saline solution and ocular hypotensive eyedrops. Anterior segment optical coherence tomography (OCT) was used as an auxiliary tool for assessing the response to treatment during follow-up time (33 months).

The term retinal vasculitis (RV) encompasses a heterogeneous group of sight-threatening conditions that are included in the intraocular inflammatory diseases that affect the posterior segment of the eye. Based on the nature of the inflammatory process, RV are classified into predominantly inflammatory or ischaemic (occlusive RV). The diagnosis is clinical and the aetiology can be infectious or non-infectious (immune-mediated). RV can be an isolated ocular syndrome or be associated with a systemic disease, of which they can represent the first manifestation...

PURPOSE: To investigate the normal range of interocular asymmetry in choroidal thickness and retinal sensitivity in high myopia without ocular fundus manifestations and to determine the relationship between interocular asymmetry and refractive error. METHODS: Forty-three patients (35.07 ± 13.31 years) with high myopia and 45 healthy participants (39.9 ± 14.1 years) were administered an ocular coherence tomography and a microperimetry examination to determine choroidal thickness and retinal sensitivity at the foveal region and at 1, 2, and 3 mm, nasally, temporally, superiorly, and inferiorly...

Congenital macular coloboma is characterized by defined punched out atrophic lesions of the macula. The present study aimed to investigate the genetic alterations of one Chinese sporadic patient with bilateral large macular coloboma. Complete ophthalmic examinations, including best‑corrected visual acuity, slit‑lamp examination, fundus examination, fundus photograph and fundus fluorescein angiography imaging, Pentacam, and optical coherence tomography were performed on the patient. Genomic DNA was extracted from leukocytes in a peripheral blood sample collected from the patient, the patient's unaffected family members and from 200 unrelated control subjects from the same population...

PURPOSE: To investigate visual function and optical quality in eyes with epiphora undergoing lacrimal passage intubation. DESIGN: Prospective case series. METHODS: Thirty-four eyes of 30 patients with lacrimal passage obstruction were enrolled. Before and 1 month after lacrimal passage intubation, functional visual acuity (FVA), higher-order aberrations (HOAs), lower tear meniscus and tear clearance were assessed. An FVA measurement system was used to examine changes in continuous visual acuity (VA) over time, and visual function parameters such as FVA, visual maintenance ratio, and blink frequency were obtained...

PURPOSE: To investigate the prevalence and characteristics of paravascular inner retinal abnormalities in healthy eyes. MATERIALS AND METHODS: In this prospective observational case series, we included 178 healthy eyes (178 patients) with no ocular diseases. Eyes with co-existing ocular diseases, e.g., epiretinal membrane, glaucoma, or high myopia, were excluded from the current study. The posterior pole and paravascular areas of the temporal arcade vessels were comprehensively examined by dense radial scanning of optical coherence tomography (OCT) with the extended field imaging technique...

The domestic chicken, Gallus gallus, serves as an excellent model for the study of a wide range of ocular diseases and conditions. The purpose of this manuscript is to outline some anatomic, physiologic, and genetic features of this organism as a robust animal model for vision research, particularly for modeling human retinal disease. Advantages include a sequenced genome, a large eye, relative ease of handling and maintenance, and ready availability. Relevant similarities and differences to humans are highlighted for ocular structures as well as for general physiologic processes...

The purpose of the current study was to identify novel mutations in the FRMD7 (FERM domain containing 7) gene and to characterize clinical features in Chinese patients with congenital motor nystagmus. For this purpose, 18 patients with congenital motor nystagmus were selected from the ocular genetic diseases bank of the Pediatric and Genetic Clinic of Zhongshan Ophthalmic Center (Guangdong, China). Direct sequencing was used to analyze the exons and adjacent introns of the FRMD7 gene. The heteroduplex‑single strand conformation polypeptide method was used to analyze 96 unrelated normal controls and gene‑screening positive patients...

PURPOSE: This is a case presentation of paracentral acute middle maculopathy in a 33-year-old white man with borderline hyperlipidemia. Paracentral acute middle maculopathy was originally thought to be a variant of acute macular neuroretinopathy; however, it is now generally accepted that these two conditions are separate disease entities. The etiology, evolution, and pathophysiology of acute macular neuroretinopathy and paracentral acute middle maculopathy are discussed, as well as current diagnostic techniques...
