Understanding the relationship between visual-angle and eye-angle for reliable determination of the field-of-view in ultra-wide field fundus photography

  title={Understanding the relationship between visual-angle and eye-angle for reliable determination of the field-of-view in ultra-wide field fundus photography},
  author={Xincheng Yao and Devrim Toslak and Taeyoon Son and Jiechao Ma},
Visual-angle has been used as the conventional unit to determine the field-of-view (FOV) in traditional fundus photography. Recently emerging usage of eye-angle as the unit in wide field fundus photography creates confusions about FOV interpretation in instrumentation design and clinical application. This study is to systematically derive the relationship between the visual-angle v and eye-angle e, and thus to enable reliable determination of the FOV in wide field fundus photography.

Figures and Tables from this paper


Trans-pars-planar illumination enables a 200° ultra-wide field pediatric fundus camera for easy examination of the retina.
By freeing the entire pupil for imaging purpose only, the trans-pars-planar illumination enables a 200° FOV PedCam, allowing easy visualization of both the central and peripheral retina up to the ora serrata. Expand
Contact-free trans-pars-planar illumination enables snapshot fundus camera for nonmydriatic wide field photography
A nonmydriatic wide field fundus camera employing trans-pars-planar illumination which delivers illuminating light through the pars plana, an area outside of the pupil is reported, which frees the entire pupil for imaging purpose only, and thus wide fieldfundus photography can be readily achieved with less pupil dilation.

Comparison of true-colour wide-field confocal scanner imaging with standard fundus photography for diabetic retinopathy screening
This study compares DR grades derived from a two-field imaging protocol from two imaging platforms, one providing a single 60-degree horizontal field of view (FOV) and the other, a standard 45-degree FOV, to identify a small number of additional patients with referable disease which are not detected with standard imaging. Expand
Portable ultra-widefield fundus camera for multispectral imaging of the retina and choroid.
Trans-pars-planar illumination for a contact-mode ultra-widefield MSI system enables a portable, non-mydriatic fundus camera, with 200° FOV in a single fundus image, and naturally enables oblique illumination ophthalmoscopy to enhance the contrast of fundus imaging. Expand
Assessment of diabetic retinopathy using two ultra-wide-field fundus imaging systems, the Clarus® and Optos™ systems
The Optos® and Clarus™ UWF retinal imaging systems were useful for examining eyes with DR, using single images obtained without mydriasis, and both systems were generally consistent in assessing DR severity. Expand
Wide-field digital retinal imaging versus binocular indirect ophthalmoscopy for retinopathy of prematurity screening: a two-observer prospective, randomised comparison
WFDRI showed relatively poor sensitivity in detecting mild forms of ROP in the retinal periphery, resulting in difficulty in making decisions to discharge infants from the screening programme, and should be regarded as an adjunct to, rather than a replacement for, BIO in routine ROP screening. Expand
Method for evaluating ophthalmic lens based on Eye-Lens-Object optical system.
The wearers can experience a comfortable wearing feeling when the evaluation method is used during the design of ophthalmic lens, and the validity of the method is demonstrated to instruct designing the progressive addition lens with the freeform surface. Expand
Evaluation of Modified Portable Digital Camera for Screening of Diabetic Retinopathy
The modified digital camera is a useful alternative technique to acquire fundus images and provides a tool for screening posterior segment conditions, including diabetic retinopathy in a variety of clinical settings. Expand
Ultra-wide-field fluorescein angiography of the ocular fundus.
Ultra-wide-field fundus fluorescein angiography offers the possibility of evaluating and quantitating peripheral retinal perfusion and vascular pathology in fundus disease. Expand
