Evaluation of Tear Film Lipid Layer Thickness Measurements Obtained Using an Ocular Surface Interferometer in Nasolacrimal Duct Obstruction Patients.

Purpose: To compare the tear film lipid layer thickness (LLT) between patients with incomplete nasolacrimal duct obstruction (NLDO) and normal controls and to analyze the changes in tear film LLT and blinking pattern after silicone tube intubation in NLDO patients.

Methods: We reviewed the medical records of 68 eyes in 52 incomplete NLDO patients who underwent silicone tube intubation from January 2017 to July 2017. The LLT, blinking pattern, and Meibomian gland image were measured with the LipiView II ocular surface interferometer.

Changes in Tear Meniscus Height Following Lower Blepharoplasty as Measured by Optical Coherence Tomography.

Purpose: The lower eyelid serves important roles in tear distribution and drainage. The purpose of this study was to measure the tear meniscus height (TMH) with anterior segment optical coherence tomography after lower blepharoplasty.

Methods: A total of 52 eyes from 26 patients treated between July 2012 and June 2015 were included in the study.
