369 Blindness and low vision Excludes: correctable impaired vision due to refractive errors (367.0-367.9) Note: Visual impairment refers to a functional limitation of the eye (e.g., limited visual acuity or visual field). It should be distinguished from visual disability, indicating a limitation of the abilities of the individual (e.g., limited reading skills, vocational skills), and from visual handicap, indicating a limitation of personal and socioeconomic independence (e.g., limited mobility, limited employability). The levels of impairment defined in the table after 369.9 are based on the recommendations of the WHO Study Group on Prevention of Blindness (Geneva, November 6-10, 1972; WHO Technical Report Series 518), and of the International Council of Ophthalmology (1976). Note that definitions of blindness vary in different settings. For international reporting, WHO defines blindness as profound impairment. This definition can be applied to blindness of one eye (369.1, 369.6) and to blindness of the individual (369.0). For determination of benefits in the U.S.A., the definition of legal blindness as severe impairment is often used. This definition applies to blindness of the individual only. 369.0 Profound impairment, both eyes 369.00 Impairment level not further specified Blindness: NOS according to WHO definition both eyes 369.01 Better eye: total impairment; lesser eye: total impairment 369.02 Better eye: near-total impairment; lesser eye: not further specified 369.03 Better eye: near-total impairment; lesser eye: total impairment 369.04 Better eye: near-total impairment; lesser eye: near-total impairment 369.05 Better eye: profound impairment; lesser eye: not further specified 369.06 Better eye: profound impairment; lesser eye: total impairment 369.07 Better eye: profound impairment; lesser eye: near-total impairment 369.08 Better eye: profound impairment; lesser eye: profound impairment 369.1 Moderate or severe impairment, better eye, profound impairment lesser eye 369.10 Impairment level not further specified Blindness, one eye, low vision other eye 369.11 Better eye: severe impairment; lesser eye: blind, not further specified 369.12 Better eye: severe impairment; lesser eye: total impairment 369.13 Better eye: severe impairment; lesser eye: near-total impairment 369.14 Better eye: severe impairment; lesser eye: profound impairment 369.15 Better eye: moderate impairment; lesser eye: blind, not further specified 369.16 Better eye: moderate impairment; lesser eye: total impairment 369.17 Better eye: moderate impairment; lesser eye: near-total impairment 369.18 Better eye: moderate impairment; lesser eye: profound impairment 369.2 Moderate or severe impairment, both eyes 369.20 Impairment level not further specified Low vision, both eyes NOS 369.21 Better eye: severe impairment; lesser eye: not further specified 369.22 Better eye: severe impairment; lesser eye: severe impairment 369.23 Better eye: moderate impairment; lesser eye: not further specified 369.24 Better eye: moderate impairment; lesser eye: severe impairment 369.25 Better eye: moderate impairment; lesser eye: moderate impairment 369.3 Unqualified visual loss, both eyes Excludes: blindness NOS: legal [U.S.A. definition] (369.4) WHO definition (369.00) 369.4 Legal blindness, as defined in U.S.A.
