Presentation
The disease most commonly presents as 1 of 3 clinical manifestations: disseminated visceral infection (with and without central nervous system involvement), isolated meningoencephalitis, and infection limited to the skin, eyes, and/or mucous membranes [ncbi.nlm.nih.gov]
Purpose: The purpose of this paper is to present a case of a Herpes simplex keratitis presenting as a case of acute corneal hydrops. Methods : Case report. [omicsonline.org]

As with all herpes simplex virus infections, there is a primary infection, followed by a latent phase, in which the virus goes into the nerve roots. Latent virus may reactivate, causing recurrent symptoms. [merckmanuals.com]
Recurrent eye infection [ edit ] Recurrent herpes of the eye is caused by reactivation of the virus in a latently infected sensory ganglion, transport of the virus down the nerve axon to sensory nerve endings, and subsequent infection of ocular surface [en.wikipedia.org]
The first is to prevent a reactivation of the latent HSV, which would result in recurrent infection and intraepithelial keratitis. [crstoday.com]
Treatment should only be initiated in primary care in exceptional circumstances - eg, in recurrent herpes simplex infection as part of a shared care arrangement with a specialist. [patient.info]

- Visual Impairment
With multiple recurrences, the herpes simplex virus can lead to significant visual impairment, which can be permanent. [merckmanuals.com]
Viral keratitis often does not cause patients severe visual impairment at initial onset. But, viruses in patients with herpes simplex virus keratitis show extremely high recurrence rates. [clinicaltrials.gov]

Patients with epithelial keratitis complain of foreign-body sensation, light sensitivity, redness and blurred vision. Focal or diffuse reduction in corneal sensation develops following recurrent epithelial keratitis. [en.wikipedia.org]
- Conjunctival Injection

The oral treatment is usually taken for seven to 10 days. “Sometimes we treat with the drops and not the pills. Other times we treat with both to blast it,” he said. “My preference is the oral treatment,” said Francis S. [eyeworld.org]
Eye Herpes Treatment Treatment for eye herpes depends on where the infection is located in the eye — in the corneal epithelium, corneal stroma, iris, retina, etc. [allaboutvision.com]
Prognosis
The prognosis in HSV keratitis, however, is generally favorable with aggressive treatment. [emedicine.medscape.com]
In patients with herpetic keratitis whose corneas are minimally vascularised (thus with reduced risk of rejection) and in whom recurrence is prevented, the prognosis for maintaining a transparent graft in herpetic keratitis is good. [bjo.bmj.com]
Prognosis [ 1, 8 ] Eyelid lesions and conjunctival disease alone tend to resolve over two weeks. [patient.info]
