چکیده
Methods: Eligibility criteria for CAPT required 10 or more large ( 125 μm) drusen in each eye. Readers graded baseline photographs from all participants and all follow-up photographs from 402 untreated eyes. Drusen and pigment characteristics were used to assign the AREDS scale score. Choroidal neovascularization was identified from fluorescein angiograms. Geographic atrophy involving the macular center was identified from color photographs.

متن کاملThe Study of Serum Asymmetric Dimethylarginine Concentrations in the Different Paraoxonase Phenotypes of Exudative Age-related Macular Degeneration Disease
Background and Aims: Age-related macular degeneration (ARMD) is a degenerative retinal disorder that causes progressive loss of central vision in older adults. The study aimed to determine the effect of asymmetric dimethylarginine (ADMA) as oxidizing metabolite and paraoxonase (PON1) activity within its phenotypes as an antioxidant agent in the development of such multifactorial disease. Mater...

متن کاملTranspupilary thermotherapy of occult subfoveal choroidal neovascularization secondary to age related macular degeneration
Abstract Background: Transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. This study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. Methods: In a ...
