In experimental group ۱, which included ۱۰ rabbits, one drop of Dorzolamide in the left eye was used twice a day, and in ۱۰ rabbits of the experimental group ۲, one drop of Timolol in the left eye was used twice a day. Five rabbits in each group on day ۱۴ and ۵ rabbits on day ۲۱ were removed and their eyes were removed for histopathological examination.
