A 22-year-old-male in whom collagen cross-linking (CXL) was done elsewhere 3 years ago for keratoconus presented with 4 × 3 mm deep corneal neovascularization [Figure 1]a in arborizing pattern [confirmed with corneal fluorescein angiography [Figure 1]c and [Figure 1]d] involving midstroma [confirmed with anterior-segment optical coherence tomography (OCT) [Figure 1]b)] with feeder vessels from 5 o'clock limbus in left eye. A presumptive diagnosis of chronic herpetic stromal keratitis was made and treated with oral acyclovir and topical low-dose steroids, causing partial regression of neovascularization with appearance of ghost vessels [Figure 1]e and [Figure 1]f.

(b) Anterior segment OCT showing involvement of midstroma (c) Corneal fluorescein angiography showing an arborizing network of neovasularization. (d) Late phase corneal fluorescein angiography showing leakage from the new vessels.

(f) Corneal fluorescein angiography showing ghost vessels (red arrows) and patchy stromal scarring (blue arrow) and decreased leakage after treatment|

Ultraviolet-A (UVA) light, epithelial/stromal trauma, or actual damage to corneal nerves during Collagen cross-linking (CXL) could trigger reactivation of latent Herpes infections even in patients with no previous history.,
