Disability grading in leprosy.

Disability Grade	Eyes	Hands and Feet
0	No eye impairment due to leprosy; no evidence of visual loss	No sensory impairment, no visible impairment
1	Eye problems due to leprosy present (irregular blink), but no vision impaired (can read fingers at six-meter distance)	Anesthesia present, but no visible deformity or damage, including muscle weakness without clawing
2	Severe visual impairments (cannot read fingers at six-meter distance), lagophthalmos, uveitis, corneal opacities	Visible impairments present, including ulcers and atrophy

The three-grade disability grading system for persons affected by leprosy was adapted from Brandsma et al. [31]. The sum of disabilities for each eye and extremity determines the Eyes-Hands-Feet (EHF) Score.
