In advanced cases, microcystic epithelial edema may be present as well. Although keratic precipitates are often present, they may be difficult to see due to the corneal edema. [eyerounds.org]

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]
