Effect of Xalacom® (Latanoprost/Timolol) and Combigan® (Brimonidine/Timolol) Fixed Combination on Intraocular Pressure and Ocular Blood Flow in Patients With Primary Open Angle Glaucoma or Ocular Hypertension

Ocular Physiology Clinical Trial

Official title:
A Double-masked Randomized Cross-over Study Comparing of the Effect of Xalacom® (Latanoprost/Timolol)and Combigan® (Brimonidine/Timolol) Fixed Combination on Intraocular Pressure and Ocular Blood Flow in Patients With Primary Open Angle Glaucoma or Ocular Hypertension

Clinical Trial Summary

Glaucoma is one of the most common causes of blindness in the industrialized nations. For a long time glaucoma has been defined as a disease in which high intraocular pressure (IOP) leads to irreversible optic disc damage and subsequent visual field loss. However, recent investigations show that IOP is not the only factor that is involved in the glaucomatous process leading to retinal ganglion cell death. The role of vascular factors in the pathogenesis of glaucoma has recently received much attention based on animal experiments and epidemiological studies. The main focus of glaucoma is still directed towards a decrease in IOP. There is, however, also considerable interest whether antiglaucoma drugs influence ocular perfusion. Although measurement of ocular blood flow is still difficult, a number of innovative techniques have been realized which cover different aspects of ocular perfusion. In the present study Xalacom® (latanoprost/timolol) and the fixed combination of Combigan® (brimonidine/timolol) will be compared with respect to their IOP lowering efficacy as well as their ocular hemodynamic effects.
