Description
Summary:To illustrate the role of corneal angiography in the clinical assessment and surgical treatment of patients with complex corneal neovascularization (CoNV). A case series of 3 patients with CoNV is presented whose management was guided by indocyanine green (ICG) and fluorescein corneal angiography. In the first case, there was recurrent lipid exudation into an intrastromal cleft from CoNV; in the second, there was progressive exudation from CoNV at the graft-host interface; in the third, CoNV was associated with rejection after deep anterior lamellar keratoplasty. In the first case, angiography helped to identify and treat the feeder vessels and stop further leakage. In the second case, it was possible using angiography to differentiate CoNV arising from iris and limbal vasculature enabling angiographic-guided fine-needle diathermy with cessation of exudation. In the third case, angiography revealed the location of CoNV in the host-graft interface after deep anterior lamellar keratoplasty, rather than within the corneal stroma. Corneal angiography is a useful diagnostic tool to guide medical and surgical management of CoNV by enabling the localization of vessel depth and topography.
