Objective:
To study the effect of Chitosan on intraocular structure and pressure when filling in the vitreous body.
Methods:
Chitosan were injected into vitreous cavity in twelve healthy vitrectomized pigmented rabbits in the right eyes (experiment group) and Hyalumnan in the left eyes (control group). Slitlamp biomicroscopy and indirect ophthalmoscopy were performed and intraocular pressure were measured pre- and postoperatively in all eyes. Histopathological examination was done after the rabbits were sacrificed at the end of the study.
Results:
All the results indicated that there were no significant differences between experiment group and control group.
Conclusion:
There is no obvious effect on intraocular structure and intraocular pressure when the vitreous cavity is filled with Chitosan.
