RESUMO
BACKGROUND: Conjunctivitis is the inflammation of the conjunctiva. Although data on clinical efficacy and safety of various ayurvedic treatments in conjunctivitis is published, systematic review is not done. This systematic review and meta-analysis aims to evaluate the efficacy and safety of ayurvedic treatments in conjunctivitis. METHODS: A literature search of the Cochrane Library (Cochrane central register of controlled trials: issue 6 of 12, June 2018), Pub Med, AYUSH research portal (Govt. of India), DHARA portal, Google scholar and online clinical trials registers was done. Randomized controlled trials (RCTs), quasi-randomized controlled trials (QRCTs), controlled clinical trials (CCTs) and multiple arms clinical trials were identified in which Ayurveda treatments with any dose, type, schedule, drug, dosage form, and advised Pathayapathya (lifestyle changes) were selected. RESULTS: We identified 13 eligible RCTs, five CCTs and two multiple arms clinical trials which includes a total of 816 participants. Meta analysis of data from five trials showed that ayurvedic treatments benefitted more compared with non-ayurveda interventions in symptoms like itching (SMD = -0.98, 95% CI (-1.30,-0.65) p < 0.00001, I2 = 38%), pain (SMD = -0.57, 95% CI (-0.87, -0.29, P = 0.0001, I2 = 0%), ropy discharge (SMD = -1.02, 95% CI(-1.45, -0.59), P < 0.00001, I2 = 0%), conjunctival congestion (SMD = -0.67, 95% CI (-0.91, -0.43), p < 0.00001, I2 = 0%), foreign body sensation (SMD = -0.68, 95% CI(-1.06, -0.29), p = 0.0006, I2 = 46%, Fig. 8) and lid heaviness (SMD = -0.66, 95% CI(- 0.98, -0.33), p < 0.0001, I2 = 0%). CONCLUSIONS: Although some findings confirm the benefit of ayurveda as opposed to non ayurveda for the treatment of conjunctivitis, since the studies have high risk of bias and are of lower quality, the findings could not be generalized. There is a need for high quality studies in ayurveda in this regard. PROSPERO REGISTRATION: CRD42019129436.
