Altered tear film dynamics, hyperosmolarity, ocular surface inflammation, and neurosensory abnormalities are the key contributors to DED pathogenesis. The presence of discordance between signs and symptoms of DED in patients and refractoriness to current therapies in some patients underpin the need for studying additional contributors that can be modulated. The presence of electrolytes or ions including sodium, potassium, chloride, bicarbonate, calcium, and magnesium in the tear fluid and ocular surface cells contribute to ocular surface homeostasis. Ionic or electrolyte imbalance and osmotic imbalance have been observed in DED and feed-forward interaction between ionic imbalances and inflammation alter cellular processes in the ocular surface resulting in DED. Ionic balances in various cellular and intercellular compartments are maintained by dynamic transport via ion channel proteins present in cell membranes. Hence, alterations in the expression and\/or activity of about 33 types of ion channels that belong to voltage-gated channels, ligand-gated channels, mechanosensitive ion channel, aquaporins, chloride ion channel, sodium\u2013potassium\u2013chloride pumps or cotransporters have been investigated in the context of ocular surface health and DED in animal and\/or human subjects. An increase in the expression or activity of TRPA1, TRPV1, Nav1.8, KCNJ6, ASIC1, ASIC3, P2X, P2Y, and NMDA receptor have been implicated in DED pathogenesis, whereas an increase in the expression or activity of TRPM8, GABA\n                    <jats:sub>A<\/jats:sub>\n                    receptor, CFTR, and NKA have been associated with resolution of DED.\n
