Corneal ulcer, also called keratitis, is an inflammatory or, more seriously, infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma. [ 1 ] [ 2 ] [ 3 ] It is a common condition in humans particularly in the tropics and in farming. [ 4 ]
Mooren's ulcer is a common form of PUK. [5] [11] One classification of Mooren's ulcer, based on the clinical presentation, includes bilateral indolent mooren's ulcer, bilateral aggressive mooren's ulcer and unilateral mooren's ulcer. [5] Unilateral mooren's ulcer, meaning ulcer of one eye, mainly affects elderly above 60 years old.
This classic herpetic lesion consists of a linear branching corneal ulcer (dendritic ulcer). During eye exam the defect is examined after staining with fluorescein dye. The underlying cornea has minimal inflammation. Patients with epithelial keratitis complain of foreign-body sensation, light sensitivity, redness and blurred vision. Focal or ...
Refractory corneal ulcer. Refractory corneal ulcers are superficial ulcers that heal poorly and tend to recur. They are also known as indolent ulcers or Boxer ulcers. They are believed to be caused by a defect in the basement membrane and a lack of hemidesmosomal attachments. They are recognized by undermined epithelium that surrounds the ulcer ...
The human eye is a wondrous thing. It is considered the body’s most complex organ after the brain and contains over 2 million working parts. About 80% of all learning happens through vision.
Mooren's ulcer is a rare idiopathic ocular disorder that may lead to blindness due to progressive destruction of the peripheral cornea.Although the etiology of Mooren's ulcer is poorly understood, recent evidence suggests that the pathogenesis of this disease appears to be the result of an autoimmune process directed against molecules expressed in the corneal stroma.
In the United States, Acanthamoeba keratitis is nearly always associated with soft contact lens use. [7] Acanthamoeba spp. is most commonly introduced to the eye by contact lenses that have been exposed to the organism through the use of contaminated lens solution, using homemade saline-based solution or tap water, or from wearing contact lenses while bathing or swimming.
Vernal keratoconjunctivitis (VKC, also Spring catarrh, Vernal catarrh or Warm weather conjunctivitis) is a recurrent, bilateral, and self-limiting type of conjunctivitis (pink eye) having a periodic seasonal incidence.
