An adaptive optics scanning laser ophthalmoscope (AOSLO) has the characteristics of a high resolution and small field view (FOV), which are greatly affected by eye motion. Continual motion will cause distortions both within frame (intra-frame) between frames (inter-frame). Overcoming achieving image stabilization is first step great importance in analysis. Although cross-correlation-based metho...

OBJECTIVE To determine the performance of RetCam vs. binocular ophthalmoscopy (BIO) in a screening program for retinopathy of prematurity (ROP). METHODS Observational comparative study with prospective data collection. Examinations with RetCam (n=169) were performed on 83 infants included in a screening program for ROP and stored for analysis at a later stage. An experienced ophthalmologist e...

BACKGROUND Many of the common systemic diseases present characteristic changes in the fundus of the eye, but fundoscopy is often performed by an ophthalmologist. Our purpose was to assess the value of fundoscopy for the general practitioners (GPs) regarding the diagnosis and management of the cases which they face in daily practice. METHODS 689 patients were referred by GPs to the outpatient ...

Purpose To compare various screening methods for the early diagnosis of retinal dysfunction in patients with long-term chloroquine (CQ) and hydroxychloroquine (HCQ) treatment. Methods Twenty patients with long-term CQ/HCQ treatment underwent ophthalmologic evaluation including visual acuity testing, ophthalmoscopy, fluorescein angiography, color vision tests, visual field and multifocal electro...

Adaptive optics (AO) describes a set of tools to correct or control aberrations in any optical system. In the eye, AO allows for precise control of the ocular aberrations. If used to correct aberrations over a large pupil, for example, cellular level resolution in retinal images can be achieved. AO systems have been demonstrated for advanced ophthalmoscopy as well as for testing and/or improvin...

We present in vivo human fundus imaging using a fiber-based confocal scanning laser ophthalmoscope (SLO). Spectrally encoded confocal scanning laser ophthalmoscopy (SECSLO) utilizes a spectral encoding technique in one dimension, combined with single-axis lateral scanning, to create video-rate reflectivity maps of the fundus. This implementation of the SLO allows for high-contrast high-resoluti...
