ANGIOPLEX USED TO STUDY CORNEAL NEOVASCULARIZATION

Objetivo

The aim of this study is to perform imaging of corneal neovascularization using spectral domain anterior segment optical coherence tomography angiography (AS-OCTA).

Método

This is a case series study of 12 eyes of 10 patients with corneal neovascularization that had the limbus and cornea analyzed by AS-OCTA in four quadrants ( superior, inferior, nasal and temporal). Causes of corneal neovascularization included: lipid degeneration, corneal transplants, corneal burns, Staphylococal blepharitis and scleral contact lens users. Vessels and neovessels at the periphery of the cornea and limbus were documented using CIRRUS™ HD-OCT 5000 with AngioPlex™ adapted with an anterior segment lens (+10D).

Resultado

All 12 eyes of 10 patients with different corneal pathologies were imaged using AS-OCTA CIRRUS™ HD-OCT 5000 with AngioPlex™. Limbal vessels and corneal neovascularization were observed and documented in all eyes being possible to determine the depth and format of the vessels.

Conclusão

AS-OCTA is a new imaging modality which allows analysis of vessels in the anterior segment of the eye. AS-OCTA CIRRUS™ HD-OCT 5000 with AngioPlex™ adapted to the anterior segment demonstrated to be an easy and applicable imaging method to study and follow corneal neovascularization. Additional studies including different corneal pathologies are needed to determine the most optimal scanning parameters in OCTA of the anterior segment.
