Correct Answer � A Explanation |

Ans.A. Lacrimal scintigraphy
The image above depicts lacrimal scintigraphy.
Tests for evaluation of watering eye include
- Regurgitation test
- Syringing
- Fluorescein dye disappearance test (FDDT)
- Jones dye test
– The primary test differentiates epiphora (overflow of tears) due to obstruction of the lacrimal passages or due to the primary hypersecretion of tears.
– The secondary (irrigation) test identifies whether epiphora is due to a functional obstruction (lacrimal pump failure) or a physical obstruction (absolute/partial obstruction).
- Dacryocystography
- Dacryoscintigraphy
