CONJUNTIVAL SMEAR EYE Detail

A Conjunctival Smear is a microscopic examination of cells and secretions taken from the conjunctiva, the thin membrane covering the white part of the eye and inner eyelids. The test is performed to help diagnose various ocular conditions, especially bacterial, viral, fungal, or allergic conjunctivitis.

The smear is collected using a sterile swab or spatula and stained using appropriate techniques such as Gram stain, Giemsa stain, or acid-fast stain, depending on the suspected condition. Under the microscope, the sample is analyzed for the presence of:

• Inflammatory cells (e.g., neutrophils, eosinophils)

• Bacteria or fungi

• Viral inclusion bodies

• Allergic markers (eosinophils)

It is commonly used in:

• Infectious conjunctivitis (bacterial, viral, fungal, or chlamydial)

• Allergic conjunctivitis

• Chronic red eye or unexplained eye irritation

• Post-operative eye infections

This test is valuable for confirming clinical suspicion and guiding targeted antimicrobial or anti-inflammatory therapy.
