Tear Meniscus Volume Changes in Dacryocystorhinostomy Evaluated With Quantitative Measurement Using Anterior Segment Optical Coherence Tomography

Abstract

The perioperative TM changes in ex-DCR can be evaluated noninvasively and quantitatively by using AS-OCT.

Prolonged increase in tear meniscus height by 3% diquafosol ophthalmic solution in eyes with contact lenses

“…TMH was defined as the line distance from the fluid surface of the CL–meniscus junction to the lower eyelid–meniscus junction. On the basis of the previously described methods,2,10,11 the lower TMH values were calculated using the cross-sectional AS-OCT images.…”

Prominent Decrease of Tear Meniscus Height With Contact Lens Wear and Efficacy of Eye Drop Instillation

“…The principles, technique, and reproducibility of this device have been described previously. 29,30 Briefly, subjects were asked to rest their head on the chin rest of the AS-OCT and instructed to blink spontaneously during the measurement. All subjects underwent AS-OCT examination 1 sec after blinking.…”

“…All subjects underwent AS-OCT examination 1 sec after blinking. In accordance with previous studies, 29,30 all AS-OCT images were processed by a single trained observer. Briefly, the procedures for the measurement of the TMH values were performed on 300% magnified images.…”

The association between ocular surface measurements with visual field reliability indices and gaze tracking results in preperimetric glaucoma

“…High TMV is also observed in patients with other ocular disorders. Ohtomo et al 16 compared TMV before and after dacryocystorhinostomy and showed that TMV is decreased after the procedure. The obstruction of the lacrimal drainage system is frequently seen in elderly patients and careful consideration is recommended when interpreting VFs in patients with high TMV or a high TFF.…”
