Current steroid therapy in dry eye disease (DED) is comprised of a 2 week duration of pulse therapy, administered twice daily (to avoid adverse effects associated with long-term steroid use). This timeframe is often too short to meaningfully resolve the inflammation associated with DED. Thus, corneal specialists, including here at MEEI, have begun using steroid treatment of at least 6 weeks with tapered dosing. In vivo confocal microscopy (IVCM) is a novel imaging technology that allows the visualization and quantification of certain corneal features associated with DED, such as hyperfluorescent superficial epithelial cells, immune dendritic cells, and sub-basal nerves. Recent cross-sectional studies have begun to shed light on the correlation of these features with traditional outcome measures typically assessed in DED, such as corneal and conjunctival staining, Schirmer's testing, tear break-up time (TBUT), and symptom questionnaires. However, longitudinal studies using IVCM to demonstrate how steroid treatment affects the corneal epithelial cells, dendritic cells and nerves are largely lacking. Furthermore, studies on the safety and efficacy of a 6 week tapered dosing steroid regimen are also lacking.
Dry eye disease (DED) is a common but often inadequately treated disease of the tears and surface of the eye. It can cause poor vision and chronic pain and is more frequent with increasing age. The 1995 Report of the National Eye Institute/Industry Workshop on Clinical Trials in Dry Eye defined dry eye as "a disorder of the tear film due to tear deficiency or excessive evaporation, which causes damage to the interpalpebral ocular surface and is associated with symptoms of ocular discomfort". The International Dry Eye Work Shop (DEWS) committee subsequently defined dry eye as "a multi-factorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is accompanied by increased osmolarity of the tear film and inflammation of the ocular surface." Typically, symptoms associated with dry eye disease include ocular burning, foreign body sensation (sand or grit), photophobia (light sensitivity), and other symptoms that result in overall long term discomfort in patients. The proposed eight week feasibility study if dry eye subjects confirmed elevated osmolarity and symptoms respond to nutritional therapy.
