Management of Dry Eye
Saleh Kamel Saleh Darwish;
Abstract
Dry eye is the most frequent disorder in ophthalmology, It is either due to tear deficiency or excessive tear evaporation
Clinical diagnostic tests of dry eye includes grading ocular surface staining, Tear break up time, and Schimer’s test. Histopathological tests such as impression cytology, conjunctival and labial salivary gland biopsy are done. Laboratory tests include Tear flourescein clearance, tear function index, tear osmolarity and analysis of protein, lactoferrin and tear lysozyme. Study of lipid layer that involves meibometry, lipid layer thickness, and lipid layer appearance are done.
Tear supplementation is the first line of treatment, artificial tears increase available tears and lower tear osmolarity through dilutional effects, however, significant advances have been made in treating many facets of dry eye including ; nonpreserved tear preparations, autologous serum and umbilical cord serum eye drops, punctual plugging and hydrogel soft contact lenses.
Corticosteroids, cyclosporine A, and tetracyclins have all been used with success to treat the secondary inflammatory response and consequential cellular changes of dry eye.
