Treatment of herpes of the eye is different based on its presentation: epithelial keratitis is caused by live virus while stromal disease is an immune response and metaherpetic ulcer results from inability of the corneal epithelium to heal.
VZV keratitis presents as a dendriform epithelial keratitis pattern early in the course of the infection. [4] ZVZ keratitis may cause clouding of the cornea, with 50% of cases involving inflammatory infiltrates in the stromal layer of the cornea, corneal scarring is a possible complication of VZV keratitis. [3]
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 ]
Peters anomaly: [18] Peters anomaly, also known as iridocorneal adhesions or keratolenticular adhesions, is a posterior corneal defect with an overlying stromal opacity, often accompanied by adherent iris strands (Peters anomaly type 1). The size and density of the opacity can range from a mild to dense central leukoma.
Nummular keratitis is a feature of viral keratoconjunctivitis. It is a common feature of adenoviral keratoconjunctivitis (an ocular adenovirus infection), [1] as well as approximately 1/3rd of cases of Herpes Zoster Ophthalmicus infections. It represents the presence of anterior stromal infiltrates.
Keratocytes are developmentally derived from the cranial population of neural crest cells, from whence they migrate to settle in the mesenchyme.In some species the migration from neural crest comes in two waves, with the first giving birth to the corneal endothelium and the second invading the epithelium-secreted stromal anlage devoid of cells; in other species both populations come from a ...
Epithelial: punctate epithelial erosions and pseudodendrites: often have anterior stromal infiltrates. Onset 2 to 3 days after the onset of the rash, resolving within 2–3 weeks. Common. Stromal: Nummular keratitis: have anterior stromal granular deposits. Occurs within 10 days of onset of rash. Uncommon
Lagophthalmos, the inability to close the eyelids completely is the main cause of exposure keratopathy.Common cause of lagophthalmos is facial nerve (CN VII) palsy. Facial nerve function may affect in several conditions like cerebrovascular accident, head trauma, brain tumors, Bell's palsy etc. Physiological inability to close the eyelids during sleep (nocturnal lagophthalmos) may also cause ...
