Tear meniscus volume in dry eye after punctal occlusion.
Purpose. To use optical coherence tomography (OCT) to evaluate the effect of punctal occlusion on tear meniscus volume in dry eye patients. Methods. Occlusion of both upper and lower puncta with collagen plugs was performed on one eye each in 20 dry eye patients and 20 normal subjects. The upper and lower tear menisci were imaged simultaneously by real-time OCT before punctal occlusion and on d...
متن کاملTear Interferometric Patterns Reflect Clinical Tear Dynamics in Dry Eye Patients.
PURPOSE We investigated whether the tear interferometric pattern was able to identify differences in tear film kinetics among clinical subtypes of dry eye. METHODS A total of 138 eyes of 76 subjects (38 men and 38 women; mean age ± SD, 61.6 ± 16.2 years) with or without dry eye who visited Itoh Clinic from May to August 2015 were enrolled in a cross-sectional study. Clinical diagnosis of dry ...
متن کاملKinetic analysis of tear interference images in aqueous tear deficiency dry eye before and after punctal occlusion.
PURPOSE Kinetic analysis of sequential tear interference images was used to investigate how the precorneal lipid film spread and distributed in aqueous tear deficiency (ATD) dry eye. METHODS One eye of 17 patients with ATD was randomly selected for this noncomparative case series. Twelve patients also had noninflamed meibomian gland dysfunction (MGD). Sequential images were digitized and anal...
متن کاملVariability of Tear Osmolarity in Patients With Dry Eye.
IMPORTANCE Knowledge about the variability of measurements using the TearLab Osmolarity System is necessary when evaluating the clinical utility of readings. OBJECTIVE To examine the variability of tear osmolarity measured by the TearLab Osmolarity System in patients with Sjögren syndrome (SS), patients with blepharitis, and control participants. DESIGN, SETTING, AND PARTICIPANTS Cross-sect...
متن کاملDifferentiation of lipid tear deficiency dry eye by kinetic analysis of tear interference images.
OBJECTIVE To use kinetic changes to characterize tear interference images in patients with lipid tear deficiency (LTD) dry eye. METHODS We used a DR-1 camera to digitize and analyze sequential images of tear interference on the central 8 mm of the cornea at the start of complete blinking in 11 healthy volunteers and 8 patients with LTD and noninflamed meibomian gland dysfunction. MAIN OUTCO...
