PURPOSE To evaluate the effect of photodynamic therapy (PDT) on perfusion and vascular integrity of choroidal neovascularization (CNV) and collateral physiological choroid. METHODS In a prospective clinical trial, patients with subfoveal CNV were treated with PDT and verteporfin. Indocyanine green angiography (ICG-A), using a confocal laser scanning system with tomographic sections, was perfo...

PURPOSE To analyze differences in the subfoveal choroidal thickness (SFChT) between bevacizumab responders (BevRs) and nonresponders (BevNRs) in patients with idiopathic central serous chorioretinopathy (CSC). METHODS The medical records of 30 unilateral chronic CSC patients who were treated with intravitreal bevacizumab (IVB) as a first line treatment were reviewed. Patients were categorized...

A 17-year-old presented with central and paracentral scotomas in his right eye for one week. There was no remarkable medical or ocular history. Blood analyses were within normal range. At presentation both eyes' best-corrected visual acuities were 20/20. Slit-lamp examination result was normal. Fundus examination revealed yellow-white hypopigmented areas in the macula. Fluorescein angiography (...

AIMS To report the optical coherence tomographic (OCT) findings in retinal pigment epithelium (RPE) detachments. METHODS 24 eyes were analysed by OCT and by fluorescein (FAG) and/or indocyanine green angiography. RESULTS RPE detachments were classified by the OCT images into those with a partial or total highly reflective line in the area of the detachment (nine eyes), and those that showed...

In the field of organic light-emitting diodes, organo-boron based thermally activated delayed fluorescence (TADF) emitters have witnessed outstanding achievements. However, it is still challenging to achieve pure blue color (CIE y < 0.20) along with high efficiencies. To overcome these hurdles, hyperfluorescence (HF) system suggests a key strategy for future display applications. Here, two TADF...

Aim: To evaluate the predictive value of fluorescence level in fundus fluorescein angiography (FFA) images for prognosis diabetic macular edema (DME). Material and Methods: In this retrospective study, 21 eyes patients who have been treated with intravitreal injection (ranibizumab, aflibercept) DME were evaluated. addition to demographic features, pre/post-treatment best-corrected visual acuity...

purpose: to report concomitant angioid streaks and skin lesions in a patient with β thalassemia. patient and findings: a 47-year-old female, a known case of b thalassemia, presented with gradual decrease of vision in her right eye. on indirect ophthalmoscopy of both eyes, angioid streaks were detected. on fluorescencin angiography, hyperfluorescence of streaks without signs of choroidal neovasc...

Herein, we demonstrate how judicious selection of donor decorating a central multi-resonant thermally activated delayed fluorescence (MR-TADF) core based on DiKTa can lead to very high-performance OLEDs. Decorating the with triphenylamine (TPA) and diphenylamine (DPA), 3TPA-DiKTa 3DPA-DiKTa exhibit bright, narrowband green red emission in doped films, respectively. The OLEDs these emitters show...
