Abstract

Purpose: To evaluate the efficacy of autologous blood eye drops in patients diagnosed with severe ocular surface disease and dry eye who were unresponsive to conventional therapy and who would otherwise be considered for autologous serum eye drops.

Methods: A total of 38 eyes of 19 patients (15 women and 4 men) with ocular surface disease and severe dry eye refractory to conventional treatment were treated with fingerprick autologous blood 4 times daily for 6 months. Follow-up visits occurred at 1-, 3-, and 6-month intervals. At each visit, visual acuity, Oxford Grading Scheme score, tear film break-up time, Schirmer test, and ocular surface disease index were measured.

Results: There was a significant improvement in the ocular surface staining score at all time gates. The mean score at presentation was 2.13, and this improved to 1.50 at 1 month (P < 0.001), 1.29 at 3 months (P < 0.01), and 1.42 at 6 months (P < 0.01). There was an improvement in tear film break-up time from 4.75 seconds at baseline to 6.79 seconds at 3 months (P < 0.01) and 7.0 seconds at 6 months (P < 0.001). An improvement in the Schirmer test was only found at 6 months with an improvement from 3.67 mm to 13.33 mm (P < 0.05). There was no statistical change in visual acuity at any time gate or ocular surface disease index score, although 83% of patients reported an improvement in their symptoms at 6 months. There were no adverse events reported.

Conclusions: Fingerprick autologous blood is an effective, readily accessible, and safe therapy for the treatment of recalcitrant cases of severe ocular surface disease and dry eye unresponsive to conventional therapy.
