BACKGROUND: To evaluate the effectiveness of platelet-rich plasma (PRP) injections in the treatment of severe dry eye . METHODS: This prospective, intervention study included patients with severe dry eye who had been diagnosed with Sjogren syndrome . Patients were divided into two groups. The intervention group received PRP (n=15) injections on days 0, 30, 60 and 90, as well as hyaluronic acid five times per day. The comparison group received hyaluronic acid (n=15) five times per day. Subjects were measured at baseline and at 30, 60 and 90 days. The primary outcome measures were changes in corneal staining according to the Oxford classification, results of the Schirmer test and tear break-up time (TBUT ). The secondary outcome measures were changes in the Ocular Surface Disease Index (OSDI) and treatment compliance . RESULTS: All subjects completed the study. The intervention group showed improvements in all primary outcome measures when compared with the control group, including a reduction in corneal staining (p<0.001), increase in the mean Schirmer value from 5.6±0.7 to 9.0±1.1 mm, and an increase in TBUT from 4.0±0.4 to 6.4±0.4 s at day 90. An improvement in subjective OSDI values was also found. CONCLUSION: PRP injection is safe and effective in improving tear parameters as well as subjective parameters, and was found to be superior to hyaluronic acid alone in the management of patients with severe dry eye . This represent a novel alternative treatment for severe dry eye . TRIAL REGISTRATION NUMBER: NCT02257957. © Author(s) (or their employer(s)) 2018. No commercial re-use. See rights and permissions.
