Density and Morphology of Corneal Epithelial Dendritic Cells are Different in Allergy.

: The role of corneal epithelial dendritic cells (CEDC), a subtype of antigen presenting cells, in ocular allergy remains largely unknown. This cross-sectional study evaluated the density and morphology of CEDC in participants diagnosed with systemic allergy, to increase our understanding of the role of CEDC in ocular inflammation associated with systemic allergy.: A convenience sample of 50 participants was categorised into allergic and non-allergic groups (31 allergic and 19 non-allergic) based on the results of skin prick test (SPT).

Contact lens wear and dry eyes: challenges and solutions.

Of the symptoms reported, sensation of dry eye is the most common.
