PURPOSE: Retinal vein occlusion (RVO) and diabetic retinopathy (DR) are two major sight-threatening diseases which may lead to neovascular glaucoma (NVG). The aim of this study was to explore the association between platelet parameters and NVG. METHODS: A total of 185 subjects were enrolled for the study from January, 2012 to December, 2015 at the Eye-ENT Hospital of Fudan University. Patients include those with NVG secondary to RVO (RVO group, n = 38), patients with NVG secondary to DR (DR group, n = 47), diabetics mellitus without retinopathy (DM group, n = 52), and healthy individuals (control group, n = 48)...

Importance: Telemedicine is becoming an increasingly important component of clinical care for retinopathy of prematurity (ROP), but little information exists regarding the role of mosaic photography for ROP telemedicine diagnosis. Objective: To examine the potential effect of computer-generated mosaic photographs on the diagnosis and management of ROP. Design, Setting, and Participants: In this prospective cohort study performed from July 12, 2011, through September 21, 2015, images were acquired from ROP screening at 8 academic institutions, and ROP experts interpreted 40 sets (20 sets with individual fundus photographs with ≥3 fields and 20 computer-generated mosaic photographs) of wide-angle retinal images from infants with ROP...

Introduction: Optical coherence tomography is an important tool for the imaging and analysis of retinal structures. The usability of conventional table-top devices is limited in children. We report on our experiences with a handheld Spectral Domain Optical Coherence Tomography (HH-SD-OCT, Bioptigen™) in infants and young children in our daily practice. Methods: Between October 2014 and April 2016, we investigated 259 patients. Indications and diagnoses were assessed. Individual examples are shown to demonstrate the advantages and disadvantages of the novel technique...

Importance: Corneal abrasions are frequent after standard (epithelium-off [epi-off]) corneal collagen cross-linking (CXL) in patients with progressive keratoconus. A new matrix therapy agent (ReGeneraTing Agent [RGTA]) has been developed to promote corneal wound healing. Objective: To assess the effect of the new type of matrix therapy agent on corneal wound healing after epi-off CXL in patients with keratoconus. Design, Setting, and Participants: This double-masked randomized clinical trial enrolled 40 patients with keratoconus undergoing epi-off CXL from July 18, 2014, to October 21, 2015, when the last follow-up was completed...

PURPOSE: Cryotherapy, introduced in the mid-1980s, was the first treatment of severe retinopathy of prematurity (ROP) and resulted in ablation of larger retinal areas than did its later substitute, laser treatment. We defined the characteristics of the retinal structure and assessed visual function, in adult ex-preterms treated with cryotherapy. METHODS: A total of 28 ex-preterms, included in a prospective study of infants born in Stockholm between September 1988 and March 1993, were treated with cryotherapy because of severe ROP...

PURPOSE: To report the successful treatment of a 78-year-old woman with bilateral mantle cell lymphoma involving the optic nerves. Chemotherapy initially was administered in the form of intravitreal methotrexate (MTX) monotherapy and was subsequently combined with systemic ibrutinib. METHODS: Retrospective case report. The diagnosis of CD5-negative mantle cell lymphoma was confirmed via immunohistopathological analysis of an axillary lymph node. Serial ophthalmologic examinations in conjunction with fluorescein angiography, fundus photography, and spectral domain optical coherence tomography were used to assess the treatment response...

PURPOSE: CLN3 is a rare lysosomal storage disorder. The majority of the patients suffer from neurological degeneration in the first decade of life leading to death in the second or third decade. One of the first symptoms is a rapid visual decline from retinal degeneration. The aim of this study was to correlate the retinal changes in CLN3 as seen with spectral domain optical coherence tomography (SD-OCT) with functional data in patients in the first years after the subjective onset of ocular symptoms...

PURPOSE: To evaluate the effects of cilostazol, an antiplatelet and vasodilation agent, on the retinal function of patients with non-proliferative diabetic retinopathy (NPDR) using a full-field electroretinogram (ffERG). METHODS: A total of 20 eyes from 20 patients were enrolled as the cilostazol-treated group, and 16 eyes from 16 patients were enrolled as the control group to assess the functional effects of cilostazol. Ophthalmologic examinations including fundus fluorescein angiography (FFA), fundus color photography, optical coherence tomography (OCT), and ffERG responses were recorded at baseline and after 1 year of cilostazol treatment...

PURPOSE: Diabetic retinopathy is one of the leading causes of blindness. There are several risk factors, such as the duration of diabetes or glycemic control of the patient; however, several biochemical factors also alter the process. Our aim was to investigate the role of soluble E-selectin in the formation of diabetic retinopathy. PATIENTS AND METHODS: Fifty-seven patients (37 female and 20 male, aged 61.71 ± 12.31 years) and 14 healthy control subjects (ten female and four male, aged 63...

OBJECTIVE: To introduce a simple method for fundus photography of dogs and cats using a smartphone and indirect ophthalmoscopy lenses. METHODS: Fundus photographs of dogs and cats with transparent ocular media were obtained with 15D, 20D, 28D, and 40D indirect lenses and an iPhone-6, in a dark room and after pharmacologic pupil dilation. The photographs were recorded as still images using a video application and a video-to-still image application. Two types of neutral density (ND) filters were used as required for reduction of the torch illumination power of the iPhone...

BACKGROUND: Egypt has one of the highest prevalence of hepatitis C virus (HCV) worldwide. Ophthalmological side effects are recognized complications of interferon (IFN) therapy. This study aimed to evaluate IFN-induced ophthalmological manifestations in patients receiving PEGylated interferon (PEG IFN) and ribavirin (RBV) and to assess the effect of IFN duration, response and systemic risk factors on the severity. METHODS: We retrospectively analyzed 100 patients with chronic HCV who were candidates for PEG-IFN and RBV therapy...

Purpose: To identify the genetic cause of autosomal recessive familial foveal retinoschisis (FFR). Methods: A female sibship with FFR was identified (Family-A; 17 and 16 years, respectively); panel based genetic sequencing (132 genes) and comparative genome hybridization (142 genes) were performed. Whole-exome sequencing (WES) was performed on both siblings using the Illumina-HiSeq-2500 platform. A sporadic male (Family-B; 35 years) with FFR underwent WES using Illumina NextSeq500...
