• With opacity of refractive media(e.g. apparent cataract) or contraction of pupils which significantly interfered the visual test or assessment of anterior segment and fundus in studied eyes

• With pseudoexfoliation syndrome, intraocular hemorrhage resulting in decreased vision, rhegmatogenous retinal detachment, macular hole or choroidal neovascularization (CNV) for any reason except for AMD (such as fundus angioid streaks, ocular histoplasmosis, pathologic myopia, trauma) in studied eyes

But patients who received verteporfin photodynamic therapy, cataract surgery or YAG posterior capsular dissection more than 3 months before screening will not be excluded.
