Purpose We evaluate feasibility and repeatability of measures for lipid peroxidation and DNA oxidation in human tears, as well as relationships between outcome variables, and compared our findings to previously reported methods of evaluation for ocular sun exposure. Methods A total of 50 volunteers were seen for 2 visits 14 ± 2 days apart. Tear samples were collected from the inferior tear me...

Dear Editor, The causes of epiphora can be separated into two categories: (1) reflex epiphora, which is caused by surface damage to the eye or infectious ocular disease, and (2) lacrimal pumping failure, which is caused by anatomical and functional failure in the outflow tract due to abnormal position of the lacrimal puncta or closure of the nasolacrimal duct [1,2]. The abnormal position of the...

PURPOSE To determine the clinical features of tear fluid signs associated with filtration blebs via three-dimensional anterior segment optical coherence tomography (3D AS-OCT). METHODS In total, 152 eyes (130 patients) with glaucoma that underwent trabeculectomy with mitomycin C were evaluated retrospectively. We investigated tear fluid signs associated with filtration blebs, using 3D AS-OCT ...

Abstract Background Tear meniscus is one of the most important indices for therapeutic evaluation in treatment obstruction lacrimal drainage system, which can be assessed by slit lamp examination and fluorescein dye disappearance test as a semi quantitative measurement. Recently Anterior Segment Optical Coherence Tomography has enabled noninvasive assessment tear meniscus. Objective To evaluate...
