Robert Walter Doyne
Encyclopedia
Robert Walter Doyne was a British ophthalmologist. He studied medicine in Oxford
, Bristol
and St. George's Hospital in London
. In 1886 he founded the Oxford Eye Hospital, and in 1909 became the first president of the Oxford Ophthalmological Congress.
In 1899 Doyne discovered colloid bodies lying on Bruch's membrane
that appeared to merge together forming a mosaic pattern that resembled a honeycomb. Afterwards this disorder was referred to as Doyne's honeycomb choroiditis. Today this condition is known to be a rare hereditary form of macular degeneration
which results in progressive and irreversible loss of vision, and goes by several names such as macula
r drusen
, malattia leventinese, dominant radial drusen and Doyne honeycomb retina
l dystrophy.
In 1889 Doyne was the first physician to describe angioid streaks
, a disorder that affects Bruch's membrane. Two years after his death in 1916, the "Doyne Memorial Lecture" was established, which is a prized distinction in British Ophthalmology.

Macular degeneration
Age-related macular degeneration is a medical condition which usually affects older adults and results in a loss of vision in the center of the visual field because of damage to the retina. It occurs in “dry” and “wet” forms. It is a major cause of blindness and visual impairment in older adults...

Macula
The macula or macula lutea is an oval-shaped highly pigmented yellow spot near the center of the retina of the human eye. It has a diameter of around 5 mm and is often histologically defined as having two or more layers of ganglion cells...

Drusen
Drusen are tiny yellow or white accumulations of extracellular material that build up in Bruch's membrane of the eye. The presence of a few small drusen is normal with advancing age, and most people over 40 have some hard drusen...

Retina
The vertebrate retina is a light-sensitive tissue lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical...
