Vishal Agrawal, a foreign exchange trader at Standard Chartered Plc, uses a white cane as he walks through the bank's office in Mumbai, India, on Thursday, June 9, 2016. Agrawal was diagnosed with the degenerative eye disease retinitis pigmentosa in 2004 as he was preparing to leave for under graduate study in U.S. Constrained by the diagnosis, he settled for studying accounting close to his home in Mumbai.
