Ocular biopsy is a procedure that involves removing a small tissue sample from the eye for examination under a microscope to diagnose conditions such as tumors, infections, or inflammatory diseases. This biopsy can be done using fine-needle aspiration, incisional biopsy, or excisional biopsy, depending on the location and nature of the tissue being sampled.

The procedure is typically performed under local anesthesia, and the tissue sample is sent to a pathologist for analysis. Ocular biopsy helps provide definitive diagnoses for conditions that are not easily identified through imaging alone.

An ocular biopsy can play a critical role in diagnosing eye cancers, retinal diseases, or unusual infections, allowing for accurate treatment planning.
