Microperimetry and psychophysical testing to aid in the determination of progression of age-related macular degeneration

INTRODUCTION Early detection and treatment of choroidal neovascularization (CNV) is crucial for achieving better visual outcomes and avoiding permanent vision loss. This fact was shown for all currently employed treatment strategies (1-4). A subgroup analysis of 24-month data from the MARINA study found initial visual acuity and CNV lesion size to be important predictors for fi nal visual acuity (5). The development of highly effective antiVEGF therapies made early detection of neovascular lesions even more important.
