What is Deaf-Blindness?
The term “individual who is deaf-blind” means any individual –
Who has a central visual acuity of 20/200 or less in the
better eye with corrective lenses, or a field defect such that the peripheral
diameter of visual field subtends an angular distance no greater than 20
degrees, or a progressive visual loss having a prognosis leading to one or both
these conditions; (ii) who has a chronic hearing impairment so severe that
most speech cannot be understood with optimum amplification, or a progressive
hearing loss having a prognosis leading to this condition; and (iii) for whom
the combination of impairments described in clauses (i) and (ii) cause extreme
difficulty in attaining independence in daily life activities, achieving
psychosocial adjustment, or obtaining a vocation;
Who despite the inability to be measured accurately for
hearing and vision loss due to cognitive or behavioral constraints, or both, can
be determined through functional and performance assessment to have severe
hearing and visual disabilities that cause extreme difficulty in attaining
independence in daily life activities, achieving psychosocial adjustment, or
obtaining vocational objectives; or
Meets such other
requirements as the Secretary may prescribe in regulation; and the term
