Visual defects are localized defect in a person's visual field. They can occur from a variety of causes such as trauma to the brain or visual pathway, diseases and disorders of the eye, optic nerve or the brain and systemic vascular disease.
Bullous keratopathy is a clinical sign of epithelial edema.
Corneal neovascularization is the growth of new blood vessels into the cornea.
Phlyctenular keratoconjunctivitis is an inflammation of the cornea and conjunctiva caused by microbial antigens.
Neurotrophic keratoconjunctivitis is a degenerative disease of the corneal epithelium resulting from impaired corneal innervation.
A disease of the surface of the eye that arises due to either decreased tear film production or increased tear film evaporation.
Exposue keratoconjunctivitis occurs when the surface of the conjunctiva or the cornea become dehydrated and damaged secondary to poor tear film wetting.
Filamentary keratitis occurs when strands of mucous and desquamated epithelial cells form corneal filaments that adhere to the corneal epithelium.
Marginal keratitis is an inflammatory reaction in the cornea characterized by subepithelial marginal infiltrates, ocular redness, increased lacrimation, photophobia and ocular discomfort.
Corneal ulcers are focal white opacities/infiltrates in the corneal stroma with an overlaying epithelial defect.
