Abstract

The study included 58 eyes of 29 dry eye patients based on Ocular Surface Disease Index (OSDI) scores, without any previous history of ocular trauma, ocular surgery or significant ocular disorders. The patients were further divided into mild, moderate and severe dry eye groups based on these scores. Anterior Segment Optical Coherence Tomography was used to assess the Tear Meniscus Height (TMH) values (primary outcome variable) and the Tear Meniscus Area (TMA) values (secondary outcome variable).

Mean TMH values of all the right and left eyes in the study were 270.69+162.2 µm and 274.69+166.65µm respectively and mean TMA value of all the eyes in the study was 0.04+0.06mm2. All values had statistically significant difference across the dry eye severity groups. Thus Tear Meniscus Height and Tear Meniscus Area values, measured on Anterior Segment Optical Coherence Tomography, have significance in distinguishing dry eye severity with the advantage of being a non-invasive procedure.
