Effects of a new hemostatic agent Ankaferd Blood Stopper® on the intraocular tissues in rat model

Purpose: To investigate the histopathological changes due to administration of Ankaferd Blood Stopper® (ABS) into intraocular tissues by an anterior chamber and intravitreal injections. Methods: Twenty Wistar albino rats were divided into four equal groups. Group 1 was injected 0.01 mL ABS into anterior chamber. Group 2 was injected intravitreal 0.02 mL ABS. Groups 3 and 4, which were used as controls, were injected into the anterior chamber and intravitreal 0.01 mL and 0.02 mL balanced salt solution (BSS), respectively. At 2, 5, 10, 15 and 20 days after injection, the eyes were examined under an operating microscope and were subsequently enucleated for histopathological examination. Results: Ophthalmic examination of the rats prior to enucleation revealed ocular complications ranging from conjunctival hyperemia to corneal perforation in group 1 and increased conjunctival hyperemia and discharge in group 2. No physical and histopathological anomalies were detected in groups 3 and 4. All eyes in group 1 showed mixed type inflammatory cell reaction, foreign-body reaction, stromal congestion, disintegration of the collagen fibers and loss of the epithelium of the posterior wall in the iris and ciliary body were observed histopathologically. All eyes in group 2 showed disintegration and separation of the retina, brown pigment accumulation and mixed type inflammatory cell reaction. Conclusion: Our results indicate that the commercially available form of ABS solution exerts a toxic effect on intraocular tissues. We consider that the intraocular use of different concentrations, rather than multiple time point of ABS should be investigated.
