Final answer:
To address the symptoms of dry eye and related issues, Tear breakup time (TBUT), Schirmer's test, and Fluorescein staining are the most relevant tests to perform, as they assess tear stability, tear production, and corneal integrity respectively.
Step-by-step explanation:
To evaluate the symptoms of dry eye, tearing, and redness, the appropriate tests are Tear breakup time (TBUT), Schirmer's test, and Fluorescein staining.
The lady's symptoms suggest a condition affecting the ocular surface and tear film stability. To assess the tear film and potential dry eye syndrome, TBUT is used to measure the time it takes for tears to break up on the surface of the eye. A quick breakup time can indicate dry eye disease. The Schirmer's test measures the quantity of tear production and is useful in diagnosing dry eye conditions by assessing if tear production is within a normal range.
Fluorescein staining helps identify any damage to the cornea or presence of foreign bodies, as the dye will highlight areas of cell loss or injury. Conjunctival impression cytology is more specialized and typically used for cellular analysis in chronic or severe cases, and may not be immediately necessary. These tests together can help determine if the patient's symptoms are due to dry eye syndrome or another condition such as conjunctivitis or keratitis.
