Lisch epithelial corneal dystrophy (LECD), also known as band-shaped and whorled microcystic dystrophy of the corneal epithelium, is a rare form of corneal dystrophy first described in 1992 by Lisch et al. [1] In one study it was linked to chromosomal region Xp22.3, with as yet unknown candidate genes.
Italian Greyhound – occurs in young dogs and is focal. Lhasa Apso – oval appearance. Mastiff – oval appearance. Miniature Pinscher – occurs at one to two years of age and is oval. Norwich Terrier – peripheral cornea. Pembroke Welsh Corgi – occurs in young dogs and can include blood vessels and pigmentation. Pointer – gray, hazy ring.
In Thiel–Behnke dystrophy, sub-epithelial corneal opacities form a honeycomb-shaped pattern in the superficial cornea. Multiple prominent gelatinous mulberry-shaped nodules form beneath the corneal epithelium during the first decade of life in gelatinous drop-like corneal dystrophy which cause photophobia, tearing, corneal foreign body ...
Apple green dichroism of subepithelial deposition of amyloid viewed under polarized light. Congo red stain. Gelatinous drop-like corneal dystrophy, also known as amyloid corneal dystrophy, is a rare form of corneal dystrophy.
As a progressive, chronic condition, signs and symptoms of Fuchs dystrophy gradually progress over decades of life, starting in middle age. Early symptoms include blurry vision upon wakening which improves during the morning, [2] as fluid retained in the cornea is unable to evaporate through the surface of the eye when the lids are closed overnight.
Microplastics were detected in almost every seafood sample found off the coast of the western U.S. in a recent study. The particles were found in the edible tissue of six different species of fish.
Epithelial basement membrane dystrophy (EBMD) is a disorder of the eye that can cause pain and dryness. EBMD, also known as map-dot-fingerprint dystrophy and Cogan microcystic epithelial dystrophy , is a corneal epithelial disease that may result in recurrent corneal erosions , irregular corneal astigmatism , and decreased vision.
Examples of epithelial dysplasia include cervical intraepithelial neoplasia – a disorder commonly detected by an abnormal pap smear) consisting of an increased population of immature (basal-like) cells which are restricted to the mucosal surface, and have not invaded through the basement membrane to the deeper soft tissues.
