Autofluorescence imaging of pingueculae
British Journal of Ophthalmology, 2008To analyse the autofluoresence (AF) properties of pingueculae and compare the size of AF with the extent of the visible lesion.Forty eyes of 23 patients with pingueculae were included in the study. AF images were obtained using an HRA2 confocal scanning laser ophthalmoscope; anterior segment photographies were obtained using TRC-50IX, IMAGEnet 2000 ...

The Nonelastic Nature of Pingueculas
Archives of Ophthalmology, 1959A pinguecula is a yellowish-white fluorescent mass situated over the sclera on one or both sides of the cornea. Its pathogenesis is far from clear, but it appears to be determined genetically and to assume tumorous proportions only in middle life or later.

The pathology of pingueculae in Gaucher's disease
Ophthalmic Genetics, 1984Several reports have noted an apparent association between pingueculae and Gaucher's disease and suggested that the yellow coloring of these lesions is attributable to Gaucher cells. The authors biopsied pingueculae from ten patients with this disorder and examined them by serial light microscopy and electron microscopy.

Pingueculae—An Association with Renal Failure
QJM: An International Journal of Medicine, 1974Abstract One hundred and forty-four patients who had chronic renal failure were examined for the presence of pingueculae. A significantly greater incidence was found between the ages of 20 to 40 in these patients compared with an age- and sex-matched control group. There was no difference in sex-incidence or between those treated with

Pterygium and Pinguecula: Electron Microscopic Study
Archives of Ophthalmology, 1967Eight pterygia alone, eight pterygia combined with pingueculae, and three pingueculae were studied by light and electron microscopy to evaluate the changes in collagen and elastic tissue that occur in these conditions. Hyaline degeneration in these growths results from an increase in the amount of a substance composed of degenerating collagen fibers ...

Relationship Between Contact Lens and Pinguecula
Eye & Contact Lens: Science & Clinical Practice, 2019Purpose: To investigate the effects of contact lens (CL) on the frequency of pinguecula, and the relationship between dry eye disease and pinguecula. Methods: Two hundred and 33 cases of soft CL wearers and 230 age-matched nonwearers were enrolled in the study.
