ABSTRACT
Objective: to compare the results of the intravitreal treatment with bevacizumab and
with triamcinolone acetonide in the macular edema secondary to branch retinal vein
occlusion.
Methods: a prospective, interventional, random and comparative study was carried
out in 34 patients. The first group (16 patients) received intravitreal triamcinolone
acetonide injection whereas the second group (18 patients) had bevacizumab
injection up to completing three doses in each group, followed by a third dose of
macular grid. The initial dose was applied three months after the occurrence of edema
and the final evaluation was made 12 months afterwards. Best corrected visual acuity
(Snellen's chart), the macular thickness and complications were assessed.
Results: in the first group, the best corrected visual acuity increased from
0,29 (0,05-05) to 0,64 (0,05-1,0) whereas in the second group it went from
0,24 (0,05-05) to 0,66 (0,1-1,0).The macular thickness of 551,3 (346-967) microns
of the first group improved when reaching 204,06 (112-449) microns and that of the
second group went from 546,2 (283-1020) microns to 181,05 (112-312) microns.
As to the complications, 25 % of patients of the first group experienced eye
hypertension, and 12,5 % of patients in the same group had cataract progression.
Conclusions: intravitreal bevacizumab injection treatment of the macular edema
secondary to branch retinal vein occlusion was better than that based on
triamcinolone acetonide injection. The complications associated to bevacizumab
treatment were fewer.
