Which illumination is useful for viewing neovascularization?

Retro illumination is a crucial technique for viewing neovascularization because it enhances the contrast between the blood vessels and the surrounding tissue. By using a light source behind the eye, the scattered light reflects off the retina and back toward the observer, allowing for better visualization of structures that would otherwise be difficult to see. This method illuminates the blood vessels, unveiling their fine details and revealing any abnormal vascular growth associated with conditions like hypoxia or inflammation which are often seen in neovascularization.

This technique is particularly valuable in contact lens examinations as it helps practitioners identify and assess complications related to lens wear, such as corneal hypoxia that can lead to neovascularization. Proper identification through retro illumination can prompt timely intervention, preserving ocular health.
