Introduction: Macular edema after central retinal vein occlusion is a common cause of vision loss. Upregulation of vascular endothelial growth factor and higher levels of inflammatory mediators have been involved in the pathogeny of the macular edema in central retinal vein occlusion. Case report: The authors report a case with non-ischemic central retinal vein occlusion that was successfully treated with a single sustained-release fluocinolone acetonide intravitreal implant...

Retinal hypoperfusion injury is the pathophysiologic basis of ocular ischemic syndrome (OIS) which often leads to severe visual loss. In this study, we aimed to establish a rat model of retinal chronic hypoperfusion by bilateral common carotid artery occlusion (BCCAO) and observe changes in the retinal function and morphology. We found that model rats showed retinal arteriosclerosis, slight dilated retinal vein, small hemangiomas, hemorrhages, vascular segmental filling, and nonperfused areas after 2 weeks of BCCAO...

PURPOSE: To identify the spectral domain optical coherence tomography predictors of visual prognosis in retinal vein occlusion macular edema after intravitreal conbercept injection. METHODS: Retrospective cohort study of 63 treatment-naive retinal vein occlusion macular edema eyes received pro re nata intravitreal conbercept with at least 3 months of follow-up. The best-corrected visual acuity (BCVA) and optical coherence tomography scans were recorded at baseline, 1 month, and 3 months after starting therapy...

Susac syndrome, a rare autoimmune disorder first described as a classic triad (encephalopathy, branch retinal artery occlusion, and sensorineural hearing loss) in 1979 by renowned physician John O. Susac, has been an advancing area of clinical interest and scientific research over the last several decades. This comprehensive review aims to succinctly highlight the breadth and detail of this enigmatic disease, with a primary focus on otologic manifestations. Topics discussed include epidemiology, pathophysiology, clinical manifestations, differential diagnoses, classification schema, laboratory investigations, characteristic audiometric findings, high-yield radiographic imaging, temporal bone histopathology, treatment strategies and overall prognosis...

BACKGROUND: Retinal vein occlusion (RVO) is a common retinal venous disorder that causes vision loss. No specific therapy has been developed. Controversy exists regarding two treatments: intravitreal dexamethasone implants and anti-vascular endothelial growth factor (VEGF). The goal of this study is to compare the effectiveness and safety of dexamethasone implants and anti-VEGF treatment for RVO. METHODS: The PubMed, Embase, and Cochrane Library databases were searched for studies comparing dexamethasone implants with anti-VEGF in patients with RVO...

PURPOSE: To evaluate the long-term cumulative probability of intraocular pressure (IOP) elevation with the intravitreal dexamethasone implant (IDI) when used to treat different indications: diabetic macular edema, uveitis, retinal vein occlusion. METHODS: 705 IDI injections (429 eyes) were assessed and Kaplan-Meier graphs were generated to assess: the probability of different levels of IOP elevation (IOP≥21, ≥25 or ≥35 mmHg), IOP change ≥10 mmHg, initiation of IOP-lowering treatment, glaucoma surgery, IOP change with repeat injections and IOP elevation in eyes with glaucoma and ocular hypertension (OHT)...

INTRODUCTION: Takayasu arteritis is a large-vessel vasculitis that may cause oculo-cerebral ischemia. We report a patient with visual loss as initial manifestation, and discuss transcranial Doppler (TCD) findings before and after surgical revascularization. CASE DESCRIPTION: A 19-year-old female developed episodes of transient positional right vision loss, progressing to permanent right vision loss and bright light-induced left amaurosis. Examination demonstrated subclavian bruits, palpable epigastrium aortic pulsation, faint radial pulses, right retinal pallor, arteriolar narrowing, and bilateral boxcarring...

Purpose: To evaluate the long-term safety of dexamethasone intravitreal implant (DEX) in patients treated for macular edema associated with retinal vein occlusion (RVO) or noninfectious posterior segment uveitis (NIPSU) in clinical practice. Patients and methods: Multicenter (102 sites in France, Germany, Spain, UK), prospective, observational, post-authorization safety study in adult patients treated with DEX. Data collected up to 2 years after enrollment included serious adverse events (SAEs) and adverse events of special interest (AESIs; adverse drug reactions that are considered important risks associated with DEX and listed in the European Union Ozurdex Risk Management Plan)...

We present a case of acute endophthalmitis after intravitreal dexamethasone implant injection and discuss the management of this rare and challenging case in which the implant could not be removed. A 50-year-old woman with a history of branch retinal vein occlusion in the right eye was treated with intravitreal dexamethasone implant injection for macular oedema. Four days after injection, the patient was admitted to the department with acute pain, decreased vision, and redness. A diagnosis of acute post-intravitreal injection endophthalmitis was made...
