Expert opinion on the prescription practice of artificial tear formulations for the management of dry eye disease in Indian settings: A questionnaire-based survey

Abstract

Clinical studies suggested that Carboxymethyl cellulose (CMC) and Hyaluronic acid (HA) were equally effective in treating DED, other studies have shown that one treatment option outperforms the other.So, this study aimed to explore expert opinions on the use of artificial tear formulations for the effective treatment of dry eye disease (DED) in Indian settings, specifically focusing on prescribing practices for different severity levels of DED. The cross-sectional, questionnaire-based study in which data was collected through a multiple-response questionnaire. The questionnaire comprised 22 questions, covering various aspects such as the clinical characteristics of DED patients and the utilization of artificial tear formulations at different stages of the disease. Among the 54 respondents, 63% of them observed a higher prevalence of DED in individuals aged 25 to 40 years. Furthermore, 77.77% of respondents identified burning or stinging in the eyes as a significant symptom of aqueous deficiency in DED patients. As a first-line treatment for mild DED, 51.85% of participants recommended 0.5% Carboxymethyl cellulose (CMC) eye drops, while 44.44% suggested using combination eye drops containing polyethylene glycol and Propylene glycol (PEG-PG) for moderate DED cases. In the case of severe DED, the majority (68.52%) of respondents preferred prescribing sodium Hyaluronate (SH) eye drops.Experts have recommended the use of CMC eye drops to provide temporary relief from itchiness and pain caused by eye dryness, wind exposure or sun exposure. They have recommended the prescription of 0.5% CMC eye drops three times daily for mild DED patients.
