We have constructed a new indirect ophthalmoscope. This instrument has a T-shaped housing composed of an illuminating tube and a viewing tube. A fiberoptic light source provides illumination. The inverted aerial image of the fundus coincides with the plane of the viewing window of the housing. This unit can be easily connected to a television camera for television ophthalmoscopy or to an image ...

Adaptive optics (AO) ophthalmoscopy allows for non-invasive retinal phenotyping on a microscopic scale, thereby helping to improve our understanding of retinal diseases. An increasing number of natural history studies and ongoing/planned interventional clinical trials exploit AO ophthalmoscopy both for participant selection, stratification and monitoring treatment safety and efficacy. In this r...

Ophthalmoscopy performed for the early diagnosis of retinopathy of prematurity (ROP) is painful for preterm infants, thus necessitating interventions for minimizing pain. The present study aimed to establish the effectiveness of human milk, compared with sucrose, for pain relief in premature infants subjected to ophthalmoscopy for the early diagnosis of ROP. This investigation was a pilot, quas...

Diabetic retinopathy (DR) and adult vitelliform macular dystrophy (AVMD) may cause significant vision impairment or blindness. Prompt diagnosis is essential for patient health. Photographic ophthalmoscopy checks retinal health quickly, painlessly, easily. It a frequent eye test. Ophthalmoscopy images of these two illnesses are challenging to analyse since early indications typically absent. We ...

PURPOSE To determine the usefulness of fluorescein angiography in studying Takayasu disease. METHODS We examined 31 eyes in 16 patients with Takayasu disease using indirect ophthalmoscopy, color photography, and fluorescein angiography. Ophthalmoscopic and fluorescein angiographic findings were compared. RESULTS Fluorescein angiography revealed no additional retinal changes in 10 eyes that ...

Objective To investigate the manifestation characteristics of fundus fluorescence angiography (FFA) and its values in diagnosing diabetic retinopathy through comparing direct ophthalmoscopy. Methods Two hundred fifty patients (500 eyes) who were suspected as diabetic retinopathy and admitted to the hospital between February 2015 and December 2016 were selected. They underwent direct ophthalmo...

PURPOSE To evaluate cone spacing using adaptive optics scanning laser ophthalmoscopy (AOSLO) in eyes with nonneovascular AMD, and to correlate progression of AOSLO-derived cone measures with standard measures of macular structure. METHODS Adaptive optics scanning laser ophthalmoscopy images were obtained over 12 to 21 months from seven patients with AMD including four eyes with geographic atr...
