Nonmydriatic Ocular Fundus Imaging on Consecutive Patients Seeking Treatment at a General Emergency Department with Vision Symptoms

Ophthalmology
Visits to emergency departments (ED) for vision symptoms are common, especially where access to eye care may be limited. However, ophthalmologists rarely are available in EDs, resulting in costly and often unnecessary transfers. Implementation of nonmydriatic color fundus photography with OCT (NMFP-OCT) in general EDs may facilitate on-site ...

Comparison of two, three and four 45° image fields obtained with the Topcon CRW6 nonmydriatic camera for screening for diabetic retinopathy

Canadian Journal of Ophthalmology, 2003
The use of the nonmydriatic camera is gaining increasing acceptance for the detection of diabetic retinopathy when integrated into a community-tailored program. We performed a study to evaluate the optimal number and positioning of photographic fields necessary to screen for diabetic retinopathy with the Topcon CRW6 nonmydriatic camera.In this ...

Multispectral Near-infrared Imaging Technologies for Nonmydriatic Fundus Camera

2019 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2019
A strong flash of light is required to obtain a clear ocular fundus image by conventional fundus camera. Patients undergo a dazzling experience, and the pupils of their eyes constrict, making it difficult to obtain continuous images or videos without a mydriatic agent.

Using Red-free Monochromatic Conversions of Nonmydriatic Digital Fundus Images

American Journal of Ophthalmology, 2007
To compare three types of digital images for assessment of retinal nerve fiber layer (RNFL) defects: red-free RNFL images, color nonmydriatic images, and digitally converted nonmydriatic red-free fundus images.Diagnostic test comparison.Ninety-five image sets of three type images were evaluated.

[Static vessel analysis in nonmydriatic and mydriatic images].

Klinische Monatsblatter fur Augenheilkunde, 2007
Static vessel analysis is a method to determine the diameter of retinal vessels in images of the ocular fundus. The suitability of non-mydriatic and mydriatic images for that method and the influence of mydriasis on the results were examined.In the prospective study, 30 eyes of 15 patients (10 women, mean age 51.6 +/- 13.2 years) were examined.

Nonmydriatic digital retinal images for determining diabetic retinopathy.

Journal of the Medical Association of Thailand = Chotmaihet thangphaet, 2007
To evaluate the efficacy of nonmydriatic digital retinal images for determining diabetic retinopathy.Single field 45-degree digital retinal images of 225 eyes from 142 diabetic patients were obtained with a nonmydriatic camera. The images were diagnosed and graded by a general ophthalmologist.
