Slit Lamp Examination Findings in Uveitis

Uveitis refers to inflammation of the uveal tract, which includes the iris, ciliary body, and choroid. Slit lamp examination plays a crucial role in diagnosing and assessing the severity of uveitis. Depending on the anatomical location, uveitis is classified as anterior, intermediate, posterior, or panuveitis , with each type presenting distinct findings under a slit lamp. 1. Anterior Segment Findings (Anterior Uveitis) Anterior uveitis is the most common form and involves inflammation of the iris and/or ciliary body. Key slit lamp findings include: Aqueous Humor Abnormalities Cells in the Anterior Chamber: White blood cells floating in the aqueous humor, graded on a scale of 0 to 4+ based on density. Flare: Increased protein content in the aqueous humor due to blood-aqueous barrier breakdown, appearing as a "smoky" or "hazy" effect under oblique illumination. Hypopyon: Accumulation of inflammatory cells in the inferior anterior chamber, seen in conditions like Behçet’s d…
