Ultraviolet Light and Fluoroquinolones in NLD Obstruction

PURPOSE: Assessment of nasolacrimal duct obstruction using fluoroquinolone eye drops and ultraviolet rays, at a tertiary care center for 6 months.
METHODS: This is a prospective cohort study where 44 adult patients coming to the ophthalmology outpatient department with watering were worked up for nasolacrimal duct obstruction by instilling one drop of moxifloxacin eye drops in each eye and after 1 minute ultraviolet light of wavelength 395 nm was used to observe the fluorescence caused by the drops.
RESULTS: Out of 44 patients, 32 patients 26 female, and 6 male had retention of the drops, indicating nasolacrimal duct obstruction which was later confirmed with lacrimal syringing. 
CONCLUSION: Using fluoroquinolone eye drops is more convenient and less cumbersome than using a fluorescein strip to assess drainage, especially in young uncooperative children for determining NLD obstruction.
