Blurred vision
Eye pain, photophobia
More pain than with typical conjunctivitis
Tearing
Perilimbic injection
Normal pupil size and intraocular pressure
Dendritic ulcers with fluorescein
May also see "geographic ulcers" - amoeba-like ulceration with dendrites at the edges
Severe cases may cause uveitis, iritis
More pain than with typical conjunctivitis
May also see "geographic ulcers" - amoeba-like ulceration with dendrites at the edges
Epithelial disease
Infectious epithelial keratitis
Corneal vesicles rarely seen; dendritic ulcers form from coalesced corneal vesicles
Enlarge into geographic ulcers, with scalloped borders
Neurotrophic keratopathy
Ulcers more oval, with smooth borders as opposed to geographic ulcers
Irregular corneal surface from immune response
Decreased corneal sensitivity due to scarring, necrosis
Stromal keratitis - develops secondarily to in 25% of patients with epithelial disease
Necrotizing stromal keratitis - leads to thinning and perforation
Immune stromal keratitis - recurrent ocular HSV
Endotheliitis (disease extending from epithelium to stroma to endothelium)
Keratic precipitates
Accompanying iritis
