Purpose: To evaluate
the effect of dorzolamide on ocular blood flow and visual field in normal
tension glaucoma.
Methods:49 eyes
which were diagnosed as normal tension glaucoma were treated with topical
Dorzolamide. Color Doppler ultrasonography and visual field tests were done
before and during the treatment. Mean follow up period was 6 months.
Results: Resistivity
index of posterior cliary arter and central retinal artery were reduced
significantly and also visual field parameters improved.
Conclusion:
Dorzolamide has potential of improving ocular circulation and visual function.
