Early Detection in Macular Disease - the handheld radial shape discrimination task and neovasular AMD

We investigated the performance of the handheld radial shape discrimination (hRSD) test in detecting the development of neovascular AMD (nAMD). Patients diagnosed with unilateral nAMD, with no nAMD in the other eye (the study eye, SE), completed the hRSD test on consecutive, routine clinic visits up to a maximum of 12, or until they were diagnosed with nAMD in the SE. Data (hRSD threshold, visual acuity, dates of tests, and demographics) from 19 “converters” who developed nAMD in the SE and 160 non-converters is available on these worksheets.
