Aim of study was to establish the possibility of application of the antifibrosis agent daunorubicin in the glaucoma surgery and to compare it with 5-fluorouracil. Twelve albino rabbits separated in two groups each of 6 rabbits underwent bilateral Cairns' trabeculectomy. Sponges soaked with 0.05 mg/ml daunorubicin solution (daunorubicin is an antineoplastic antibiotic of the family of anthracyclines closely related to doxorubicin) were applied on the right eyes under the scleral flaps (group 1) for 3 minutes followed by irrigation with 0.9% sodium chloride solution (saline). In group two, 5-fluorouracil solution was applied in the same manner for 3 minutes in the right eyes by a sponge soaked with 0.5 mg/ml. In the left eyes of both groups, a sponge soaked with 0.9% saline was applied. Histological and electron microscopical study was performed on the 4th month. Histological and electron microscopical changes of toxic origin of the adjacent episclera, sclera and cornea were not found neither in the group with daunorubicin nor in the mitomycin C group nor in the control eyes with saline. In daunorubicin eyes and in 5-fluorouracil eyes, filtration blebs were high and with no cicatrisation. Very few fibroblasts were observed by light and electron microscopy. The examination of conjunctiva of the filtering bleb revealed irregular epithelium. Substantia propria contained only a few cells and no vessels. Advanced cicatrisation was observed in the control eyes treated with saline. The results suggest that the application of daunorubicin is possible as alternative of 5-fluorouracil for the glaucoma filtration surgery.
