Retinal imaging with smartphone
Nigerian Journal of Clinical Practice, 2017The use of smartphones for various purposes among health professionals is increasing, especially with the availability of different applications. On account of cost, fundus cameras are not readily available in ophthalmic practice in developing countries.

Advances in Retinal Imaging: Retinal Amyloid Imaging
2020Growing evidence indicates that the brain is not the only CNS tissue affected by Alzheimer’s disease (AD) pathology—the retina is also afflicted with the pathological hallmarks Aβ and tau, as well as associated inflammation, neurodegeneration, astrogliosis, and vascular abnormalities.

SIMULATION OF A RETINAL SCOTOMA BY A STABILIZED RETINAL IMAGE
Ophthalmic and Physiological Optics, 1987Abstract— Two methods are described for simulating a retinal scotoma by means of a stabilized retinal image, hence allowing some aspects of the impairment of visual function associated with scotomas to be studied in observers with normal visual fields. In the first method, an optical lever arrangement is used to

Hybrid Retinal Image Registration
IEEE Transactions on Information Technology in Biomedicine, 2006This work studies retinal image registration in the context of the National Institutes of Health (NIH) Early Treatment Diabetic Retinopathy Study (ETDRS) standard. The ETDRS imaging protocol specifies seven fields of each retina and presents three major challenges for the image registration task.

Ophthalmic and Visual Optics, 1991
Retinal imaging is a highly specialized form of microscopy. The microscope objective is the subject's lens and cornea, not what any microscopist would choose. The working distance is fixed at about 20 mm, and the object is shielded from any light except what comes through the objective or (in rare cases) through the eyeball from "behind".

Multimodal Retinal Imaging: An Introduction
2013Multimodal retinal imaging is a new concept in the diagnosis and follow-up of retinal disorders. It refers to the importance of combining diagnostic information related to both retinal morphology and function in a unique setting, possibly in a unique multifaceted image, to improve the final diagnostic result. When a multimodal imaging approach is used (

MULTIMODAL RETINAL IMAGING IN ACHROMATOPSIA
RETINAL Cases & Brief Reports, 2014To investigate comprehensive image findings in a patient with incomplete achromatopsia.Observational case report.A 12-year-old girl was referred to our clinic with nystagmus, photophobia, poor best-corrected visual acuity, and impaired color vision since she was 5 years old. Her best-corrected visual acuity was 20/200 for both eyes.

Image Analysis of Retinal Images
2011The eye is sometimes said to provide a window into the health of a person for it is only in the eye that one can actually see the exposed flesh of the subject without using invasive procedures. That ‘exposed flesh’ is, of course, the retina, the light sensitive layer at the back of the eye. There are a number of diseases, particularly vascular disease,

Kepler's Discovery of the Retinal Image
Archives of Ophthalmology, 1973was deeply involved in analyzing the data, concentrating on the orbit of Mars. Eventually, he was to describe this orbit as elliptical in three histor¬ ic, mathematically precise state¬ ments on planetary motion. The first laws of nature in the modern sense, Kepler's equations were to provide Newton the basis for universal gravi¬ tation.
