Dry eye is a significant adverse effect of isotretinoin causing patients to use ophthalmic medications. For this reason, many patients using isotretinoin are referred to ophthalmology clinic because of discomfort symptoms. In the literature, there are studies suggesting superiority of Autologous serum drops regarding effects on ocular surface when compared to artificial tear. In addition, Autologous serum was also used in several corneal pathologies with successful outcomes. No data regarding use in the ocular adverse effects of isotretinoin was found in the literature; however, investigators think that it may be an effective alternative in the treatment of dry eye developed during isotretinoin use due to positive effects on ocular surface, epithelial regeneration and anti-inflammatory effect. Autologous serum can be a choice of ophthalmologists in routine practice by increasing number of comprehensive studies investigating effectiveness, safety and long-terms effects of Autologous serum therapy.In this study, it was aimed to investigate dry eye development in the patients receiving systemic retinoic acid therapy and to compare effectiveness of Autologous serum and Preservative free artificial tear in the patients with dry eye disease.
