Of them, 13 received anisodine hydrobromide and butylphthalide-sodium chloride injection continuously for 10\u2009days as basic treatment in the control group, and 12 received two tenon capsule injections of PRP on a 10\u2009days interval as an additional treatment in the PRP group. We compared the best-corrected visual acuity (BCVA) and capillary perfusion density (CPD) of radial peripapillary capillaries and the moth-eaten eara of the peripapillary superficial capillary plexus and deep capillary plexus at 1\u2009day (D1) before the first PRP treatment and 7\u2009days (D7), 14\u2009days (D14), and 30\u2009days (D30) after the first PRP injection.
