Lissamine green stain is a diagnostic dye used by eye doctors to evaluate the ocular surface. It stains damaged, devitalized, or poorly protected cells on the conjunctiva and cornea. The dye is commonly used in dry eye testing and ocular surface disease evaluation. It helps show surface changes that can be hard to see during a standard exam.

Areas with damaged or unhealthy surface cells can hold the dye and become easier to see at the slit lamp. Staining patterns can help the clinician judge the location and severity of ocular surface disease. This can support diagnosis and treatment planning for dry eye and related conditions.
Lissamine green is used when an eye doctor is checking for dry eye disease, keratoconjunctivitis sicca, exposure-related surface damage, or conjunctival staining. It can help assess the conjunctiva and lid-wiper area, which can be involved in dry eye symptoms. Symptoms that can lead to testing include burning, grittiness, watering, redness, and fluctuating vision. The dye is used with other exam findings rather than as a stand-alone diagnosis.
Lissamine green and rose bengal can show similar ocular surface staining patterns. Lissamine green is commonly preferred because it can cause less discomfort and has lower surface toxicity than rose bengal. Rose bengal can sting more during application. The clinician chooses the dye based on the exam goal and patient comfort.
Lissamine green is generally well tolerated, but temporary stinging, tearing, redness, or blur can happen. Contact lenses should be handled according to the eye doctor's directions after staining. The dye is used for examination and does not treat the underlying eye surface problem. Worsening pain, discharge, reduced vision, or persistent redness after an exam should be reported.
It shows damaged, devitalized, or poorly protected cells on the ocular surface. Eye doctors use the staining pattern to help evaluate dry eye and related surface disease.
It can cause mild temporary stinging, but it is commonly better tolerated than rose bengal. Discomfort should fade quickly after the test.
No, lissamine green and fluorescein are different diagnostic dyes. Fluorescein is widely used for corneal defects and tear breakup, while lissamine green highlights ocular surface cell damage.
No, it is one part of a dry eye evaluation. The eye doctor also considers symptoms, tear film findings, eyelid health, and other exam results.
