Purpose: To evaluate the efficacy and safety of plasma rich in growth factors eye drops for the treatment of corneal and ocular surface disorders in patients with graft versus host disease.
Methods: This retrospective and longitudinal study included graft versus host disease patients with ocular disorders. The resolution of corneal ulcers (area and density staining) was evaluated as primary outcome. Best corrected visual acuity, intraocular pressure, tear film breakup time, Schirmer test, ocular surface disease index, and visual analog score were evaluated as secondary outcomes. All variables were analyzed before and after plasma rich in growth factors treatment. The safety of plasma rich in growth factors treatment was also assessed.
Results: Twelve patients (23 eyes) with ocular graft versus host disease were evaluated. Statistically significant improvement in the area (75.7%) and density (73.3%) of the corneal staining, in best corrected visual acuity (74.7%), in ocular surface disease index scale (75.4%), visual analog score frequency (81.4%) and visual analog score severity (81.9%), and an increase of 3.8 s in tear film breakup time and 6 mm in Schirmer test was observed after plasma rich in growth factors treatment (p < 0.001). Some potential modifiers of the therapeutic effect were identified. All patients achieved corneal stability without perforation risk. No adverse events associated with the plasma rich in growth factors were observed.
Conclusion: Immunosafe plasma rich in growth factors eye drops for the treatment of patients with ocular graft versus host disease could be safe and effective, showing a high rate of corneal ulcer resolution and dry eye disease control. Plasma rich in growth factors eye drops may help to maintain corneal stability and prevent it against higher ocular complications.
