How to use…the direct ophthalmoscope
Archives of disease in childhood - Education & practice edition, 2017Ophthalmoscopy and red reflex examination are core medical skills required to identify sight-threatening and life-threatening disease. We discuss the predictive utility and limitations of findings with an ophthalmoscope and tips as to how to optimise these.

Directional light scanning laser ophthalmoscope
Journal of the Optical Society of America A, 2005The cone photoreceptor mosaic of the living human eye has in a limited number of cases been imaged without the use of wavefront-correction techniques. To accomplish this, the directionality of the photoreceptors, as manifested by their waveguiding properties, may be used to advantage.

Ownership of direct ophthalmoscopes by medical students
Medical Education, 1992Summary. In September 1986 the Department of Education and Science withdrew the equipment grant for clinical medical students. This coincided with a reduction of 50% in the level of ownership of direct ophthalmoscopes amongst a group of 51 medical students who commenced their medical studies after September 1986

USING THE FULL RESOURCES OF THE DIRECT OPHTHALMOSCOPE
Optometry and Vision Science, 1970ABSTRACT Modern direct ophthalmoscopes offer a broad selection of filters, apertures and focal powers. Their use, with the increase in available illumination, permits the informed examine to make a more definitive examination of the ocular fundus and intervening media. When a first examination

Previous studies have shown that the cup:disc (C/D) ratio has limited sensitivity and specificity. Improved sensitivity and specificity has been found with combinations of disc parameters using stereophotography or disc imaging, but the extent to which these studies reflect what can be achieved by direct assessment is unclear. The purpose of this paper
