  1. M: male; F:female; OD: right eye; OS: left eye; SE: spherical equivalent; BCVA: best-corrected visual acuity; BSPD: bone spicule pigmentation deposit; ARA: attenuated retinal arteries; WOD: waxy‐pale optic disc; MA: Macular atrophy; SNHL: sensorineural hearing loss; NE: none; according to the visual impairment standards established by WHO in 2019, the best corrected visual acuity (BCVA) of the better-seeing eye being less than 0.5 but equal to or greater than 0.3 is classified as mild visual impairment, if which being less than 0.3 but equal to or greater than 0.1, it is classified as moderate visual impairment, if which being less than 0.1 but equal to or greater than 0.05, it is classified as severe visual impairment, and if which being less than 0.05 is classified as blindness.
