Spheroidal degeneration of cornea and conjunctiva.
A study of almost 1000 outpatients at a London eye hospital showed the presence of asymptomatic yellowish, spheroidal deposits in the peripheral cornea or conjunctiva, or both, in about 6 per cent, with a preponderance of males and older subjects among those affected. This prevalence is less than is observed in people in countries exposed to higher levels of sunlight. Histological study of the ...
متن کاملAetiology of spheroidal degeneration of the cornea in Labrador.
To determine the aetiology of spheroidal degeneration of the cornea (Labrador keratopathy), total population surveys were conducted in 5 communities in coastal Labrador and northern Newfoundland. For 4 years records were also kept on all clinic patients aged 40 or more throughout the region. Both methods gave a peak prevalence at latitudes 55 degrees--56 degrees north. The greatest severity and...
متن کاملHistology of spheroidal degeneration of the cornea in Labrador.
Nine specimens of the corneas of patients from Labrador and Northern Newfoundland affected by spheroidal degeneration (climatic droplet keratopathy) have been examined microscopically. Histochemical stains confirmed studies of similar corneal degenerations from other geographical areas that the droplets contain a protein which does not have all the characteristic properties of elastic tissue. S...
متن کاملSurface features of the conjunctiva and cornea.
Guinea pig corneal and conjunctival surfaces were examined by transmission electron microscopy and cytochemistry. Some specimens of cornea and conjunctiva were examined morphologically; others were stained with ruthenium red or tannic acid before examination to enhance the detection of glycoproteins at cell surfaces. The epithelia were covered by microvilli and on the cornea also by microplicae...
متن کاملPreinvasive carcinoma of the cornea and conjunctiva.
Greyish-white spots, varying in size, caused diagnostic problems in 2 patients with pre-invasive corneal carcinoma. Keratectomy specimens permitting light and electron microscopy indicated that the smaller spots predominating in one patient correlated with epithelial microcysts and vacuoles, while areas of parakeratosis accounted for the macroscopic white patches found in the other. A variety o...
