PURPOSE: Fumagillin has been previously used to treat corneal microsporidial keratitis and also identified as an angiogenesis inhibitor. This study aimed to evaluate efficacy of fumagillin bicyclohexylamine on the rat model of corneal neovascularization induced by silver nitrate cauterization. METHODS: Twenty-four Albino Wistar rats (n = 24) were divided into three groups. Following silver nitrate-induced corneal injury, eyes in Group 1 received one drop of 5 mg/mL topical fumagillin bicyclohexylamine four times daily for 10 days...

PURPOSE: To describe the macroscopic characteristics of the subretinal fluid (SRF) and its spilling modality during evacuative puncture in scleral buckling (SB) surgery for rhegmatogenous retinal detachment. METHODS: We retrospective reviewed all the SB surgeries performed over a period of 26 months at the University Eye Clinic of Trieste, Italy. We selected a cohort of 102 patients in which SRF drainage by means of evacuative puncture was performed. A high-definition video was recorded during the whole duration of the procedures, and the macroscopic characteristics of the SRF leakage were assessed...

PURPOSE: The aim of this study was to investigate whether intraoperative 360° prophylactic endolaser photocoagulation is necessary for the treatment of uncomplicated retinal detachment. METHODS: This prospective, randomized, comparative and interventional study includes 50 consecutive patients with primary rhegmatogenous retinal detachment (RRD) who were treated by pars plana vitrectomy. The patients were divided into two groups: in Group A endolaser applied to all existing breaks as well as a 360° laser retinopexy, while Group B received endolaser only to the retinal breaks...

REVIEW
Mohammad Ali Shahab, Tahreem Aman Mir, Sidra Zafar
INTRODUCTION: Uveitis encompasses a wide variety of sight-threatening diseases characterized by intraocular inflammation. It is often classified as infectious and non-infectious uveitis. Unlike infectious uveitis, a distinct infectious agent cannot be identified in non-infectious uveitis and disease origin is usually autoimmune, drug related, or idiopathic. THE ISSUE AT HAND: Non-infectious uveitis can often have a relapsing-remitting course, making it difficult to treat, and poses a significant challenge to ophthalmologists...

INTRODUCTION: Causes of macular edema are multifactorial, but inflammation, vascular factors and mechanical traction are of major importance. Therapeutic options of macular edema depend on the underlying cause. Intravitreal administration of inhibitors of vascular endothelial growth factor leads to inhibition of retinal neovascularization and subsequent edema. OBJECTIVE: Fumaric acid esters are successfully used in dermatology for years according to their antiangiogenic and anti-inflammatory effects...

PURPOSE: To compare sub-tenon steroid plus anti-VEGF injection with anti-VEGF injection solely in the treatment of resistant diabetic macular edema (DME). METHOD: Patients who exhibited insufficient anatomic [over 350 μm central macular thickness (CMT)] and less than 3 lines of visual gain at least six anti-VEGF injections, were randomly divided into two groups. In group I, the anti-VEGF injection was performed 10 days after the sub-tenon steroid injection [Triamcinolone acetonide (Sinakort-A® )]...

Ali Asghar Sarchahi, Mehdi Eskandari
PURPOSE: To measure IOP in animals, it is often necessary to use topical anesthetics. The use of these drugs may cause changes in IOP and interfere with the final results. To address this issue, the effects of four local anesthetics (tetracaine, proparacaine, lidocaine, and bupivacaine) on IOP were investigated in ten adult dogs. METHODS: One drop of tetracaine was instilled in the right eye of half of the dogs and in the left eye of the other dogs; normal saline was instilled in the fellow eyes...

PURPOSE: We aimed to analyze the clinical characteristics of idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome. Furthermore, we aimed to correlate the number and location of retinal aneurysms with the size of retinal non-perfusion area and neovascularization. METHODS: Six patients with IRVAN syndrome (1 male and 5 females, age 5-38 years) were enrolled in this study. Fundus fluorescein angiography (FFA) was used to determine the total number of retinal aneurysms, number of aneurysms within the first branch of the retinal artery, minimum distance between the non-perfusion margin and the optic disc, and the number of retinal aneurysms in each quadrant, as well as the type of neovascularization...
