García-Conca V, et al. - Experts assessed and compared the symptomatology and clinical findings in hyposecretory dry eye of the treatment with platelet-rich plasma (PRP) and artificial tears of sodium hyaluronate (SH). A more significant positive effect over symptomatology and different dry eye signs is induced by PRP treatment in the hyposecretory dry eye than SH, especially in moderate and severe cases. In the PRP group, strong and statistically significant correlations were found of the change achieved in visual acuity, hyperaemia, osmolarity, and conjunctival and corneal staining with the baseline values of these variables.
