PURPOSE: This study aimed to evaluate the relationship between macular structural changes and visual prognosis after pars plana vitrectomy (PPV) for proliferative diabetic retinopathy. METHODS: The study included 60 eyes that had undergone PPV. Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. RESULTS: From the preoperative OCT, normal fovea with/without traction, normal fovea with preretinal hemorrhage, and tractional retinal detachment involving fovea showed an increase in BCVA after PPV (all p < 0...

PURPOSE: To determine whether internal limiting membrane (ILM) peeling during pars plana vitrectomy for rhegmatogenous retinal detachment reduces the incidence of epiretinal membrane (ERM) formation. METHODS: In this retrospective study, preoperative, intraoperative, and postoperative data from all eyes undergoing pars plana vitrectomy for rhegmatogenous retinal detachment between January 2007 and December 2013 was analyzed. All cases with at least 1-year of follow-up were included...

The purpose of this study was to compare steroid hormone concentration levels in the vitreous and serum of vitreoretinal disease patients to elucidate the possibility of neurosteroid production in the retina. Serum and vitreous samples were collected from vitrectomy patients, and estradiol (E2) and testosterone (T) concentrations were measured using electro-chemiluminescence immunoassay. We measured E2 in epiretinal membrane (ERM, n = 14), macular hole (MH, n = 18), proliferative diabetic retinopathy (PDR, n = 20), and retinal detachment (RD, n = 19) cases, and T in ERM (n = 14), MH (n = 17), PDR (n = 13), and RD (n = 17) cases...

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...

Purpose: Osteoprotegerin (OPG) is a novel regulator of endothelial cell function, angiogenesis, and vasculogenesis. We correlated expression levels of OPG with those of the angiogenic and inflammatory factors vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1/CCL2) in proliferative diabetic retinopathy (PDR). We also examined expression of OPG in retinas from diabetic rats and diabetic patients and measured production of OPG by human retinal microvascular endothelial cells (HRMEC) and investigated its angiogenic activity...

A 6-year-old boy diagnosed as anisometropic amblyopia, with only café-au-lait spots and a family history of neurofibromatosis, presented with decrease in vision in the both eyes. Dilated fundus examination showed epiretinal membrane in both eyes over the macula. He underwent successful surgical management of the epiretinal membrane.

PURPOSE: This study proves the possibility of targeted use of the nonsteroidal anti-inflammatory drug lornoxicam to prevent the development of proliferative vitreoretinopathy (PVR). Triamcinolone acetonide (TA) was selected as a reference substance. METHODS: Wistar rats (N = 400) were used. PVR was modeled by intravitreal injection of dispase or concanavalin A. Lornoxicam or TA intravitreal administration was performed 20 min later. On the second and the third day, drugs were administrated systemic...

PURPOSE: This study aims to evaluate and correlate the levels of interleukin-6 (IL-6) and thrombin-antithrombin III complex (TAT) in the vitreous of patients with different vitreoretinal pathologies. METHODS: Vitreous samples were collected from 78 patients scheduled for pars plana vitrectomy at a tertiary medical center. Patients were divided by the underlying vitreoretinal pathophysiology, as follows: macular hole (MH)/epiretinal membrane (ERM) (n = 26); rhegmatogenous retinal detachment (RRD) (n = 32); and proliferative diabetic retinopathy (PDR) (n = 20)...

BACKGROUND: To describe the characteristics of patients with syphilitic uveitis in northern China. METHODS: A case series of 21 patients (33 eyes) diagnosed with syphilitic uveitis from 2011 to 2016 at a tertiary center in northern China was retrospectively analyzed. RESULTS: Twenty-one patients (33 eyes) were diagnosed as syphilitic uveitis. Posterior segment involvement was found in 32 eyes (97.0%). Vitreous haze, neuroretinitis, and posterior placoid chorioretinitis were mainly found in patients with a relatively short duration of the disease, while diffuse chorioretinitis, pseudoretinitis pigmentosa, cystoid macular edema, and epiretinal membrane were found in patients with relatively long duration of ocular involvement...

CASE REPORT: The case involves a 35-year-old man, with a history of retinitis pigmentosa, who presented with a bilateral cystoid macular oedema associated with bilateral epiretinal membrane, which was resistant to treatment with oral acetazolamide and intravitreal bevacizumab. The treatment with oral eplerenone was able to improve the visual acuity and macular thickness of this patient. DISCUSSION: A variety of treatments have been proposed for the management of cystoid macular oedema, associated with retinitis pigmentosa, with variable results...
