BACKGROUND Neoplasms of the retinal pigment epithelium (RPE) are rare, and little is known about their clinical variations, clinical course, and prognosis. Although most are benign, they can simulate choroidal melanoma. OBJECTIVES To evaluate the clinical characteristics, management, pathological features, and prognosis of acquired neoplasms of the RPE (adenoma and adenocarcinoma) and to defi...

Developing high-efficiency purely organic blue light-emitting diodes (OLEDs) that meet the stringent industry standards is a major current research challenge. Hyperfluorescent device approaches achieve in large measure desired high performance by combining advantages of thermally activated delayed fluorescence (TADF) assistant dopant with narrowband deep-blue multi-resonant TADF (MR-TADF) termi...

Hidden photophysics is elucidated in the very well-known thermally activated delayed fluorescence (TADF) emitter, DMAC-TRZ. A molecule that, based on its structure, considered not to have more than one structural conformation. However, experimental and computational studies, two conformers, a quasi-axial (QA) quasi-equatorial (QE) are found, effect of their co-existence both optical electrical ...

PURPOSE The purpose of this study is to assess indocyanine green angiographic findings in patients with nonfamilial amyloidosis. METHODS The method used was a prospective study including seven patients (14 eyes) with nonfamilial amyloidosis. All patients underwent detailed ophthalmic clinical examination, fundus photography, and indocyanine green angiography (ICGA). Fluorescein angiography (F...

Purpose. To investigate if there is a prognostic implication of the presence of cellular debris in the anterior vitreous in patients with Behçet's disease (BD) without any ocular symptoms. Methods. One hundred and twenty eyes of 60 patients with BD were included in the study. The eyes were divided into two groups according to the presence of cellular debris in the anterior vitreous. The first g...

Purpose Leukemias can involve almost every part of the human eye. Ophthalmic manifestations of leukemias can be divided into direct infiltration, secondary vascular changes and neuro-ophthalmological changes. Our case presented with exudative retinal detachment mimicking Vogt Koyanagi Harada's disease (VKH). Observations A 30-years old Asian (Indian) female presented with insidious onset of p...

Optical Coherence Tomographic Angiography of Choroidal Neovascularization Associated With Central Serous Chorioretinopathy Choroidal neovascularization (CNV) can complicate chronic central serous chorioretinopathy (CSC) and may be difficult to diagnose because CSC itself can be associated with pigment epithelial detachment, subretinal fluid, and ill-defined patterns of hyperfluorescence on fluo...

Plaques of hard exudate measuring 0-5 to 10 disc diameters, which occurred in 5 eyes of 4 patients with diabetic maculopathy, showed complete organisation in 8 to 18 months with the formation of scars measuring 0-2 to 0 5 disc diameters. The visual acuity was related to the size and situation of the scar within the fovea, and, when the foveola was involved by plaque formation, visual reduction ...

The current study presents the case of a patient with a rare adverse event characterized by sudden vision loss in the untreated eye following an intravitreal injection of bevacizumab for neovascular glaucoma (NVG). The patient was diagnosed with NVG refractory to Ahmed glaucoma valve implantation and a vitreous hemorrhage in the right eye, which was treated with 1.25 mg intravitreal bevacizumab...
