Optical Coherence Tomography Angiography for Evaluation of Conjunctival Vessels in Dry Eyes

Figure 1

Representative images of conjunctival blood vessels. (a) The area of interest for optical coherence tomography angiography (OCTA) scanning is delineated in the box on the left. The OCTA scan area is 6 × 6 mm after tangential alignment with the corneal limbus, with a subsequent selection of a clear 3 × 3 mm region to ensure precise vascular analysis. (b) Aristotle processed pictures following image manipulation. These images exhibit distinctly marked vascular networks, alongside error identification aimed at discerning pseudoshadows from conjunctival vascular networks.
