| Abstract;Purpose: To observe changes in tear film lipid interference patterns on the ocular surface in patients with nasolacrimal duct (NLD) obstruction before and after dacryocystorhinostomy (DCR). Methods: The tear film lipid layer on the ocular surface was observed with a specular reflection video recording system in 5 eyes of 4 patients with NLD obstruction before and after DCR. Precorneal tear lipid layer interference patterns at the central cornea, tear meniscus height (TMH), and the Shirmer I test were recorded. Observed patterns were classified into 5 grades. Results: Three of four eyes with TMH values over 0.4 mm before DCR showed decreased TMH postoperatively. One eye with a TMH of 0.2 mm showed no change after DCR. Concerning the tear film lipid layer interference patterns, 4 eyes were classified as grade 1 or 2, and 1 eye was classified as grade 4 before DCR. After DCR, the 5 eyes were classified from grade 3 to grade 4. Epiphora was successfully resolved in all patients after DCR. Conclusion: Tear film lipid layers were classified as normal grades before DCR but most cases changed to high grades after DCR. We suggest that the eye after DCR should have a thicker lipid layer than before DCR. (author abst.) |
