Recurrent corneal erosion (RCE) is a disorder of the eyes characterized by the failure of the cornea's outermost layer of epithelial cells to attach to the underlying basement membrane (Bowman's layer). The condition is excruciatingly painful because the loss of these cells results in the exposure of sensitive corneal nerves.
Doxycycline, at subantimicrobial doses, inhibits MMP activity, and has been used in various experimental systems for this purpose, such as for recalcitrant recurrent corneal erosions. It is used clinically for the treatment of periodontal disease and is the only MMP inhibitor that is widely available clinically.
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.
Doxycycline is more stable than tetracycline for this purpose. [152] At subantimicrobial doses, doxycycline is an inhibitor of matrix metalloproteases, and has been used in various experimental systems for this purpose, such as for recalcitrant recurrent corneal erosions. [153]
Recurrent corneal erosions may occur. The hallmark of Schnyder corneal dystrophy is the accumulation of crystals within the corneal stroma which cause corneal clouding typically in a ring-shaped fashion. [citation needed] Posterior corneal dystrophies – Fuchs corneal dystrophy presents during the fifth or sixth decade of life. The ...
Due to the different underlying causes, proper diagnosis, treatment, and prognosis can only be determined by an eye care professional. Punctate epithelial erosions may be treated with artificial tears. In some disorders, topical antibiotic is added to the treatment.
More significant injuries like a corneal ulcer, globe rupture, recurrent erosion syndrome, and a foreign body within the eye should be ruled out. [1] Prevention includes the use of eye protection. [1] Treatment is typically with antibiotic ointment. [1] In those who wear contact lenses a fluoroquinolone antibiotic is often recommended. [1]
These recurrent painful corneal epithelial erosions often begin as early as 1 year of age. [1] With time, the corneal changes progress into opacities in Bowman's layer, which gradually becomes more irregular and more dense. [1] Significant vision loss may occur. [2] However, vascularization of the cornea is not present. [2]
