The table below gives a classification of severity of visual impairment recommended by a WHO Study Group on the Prevention of Blindness, Geneva, 6-10 November 1972.

The term 'low vision' in category H54 comprises categories 1 and 2 of the table, the term 'blindness' categories 3, 4 and 5, and the term 'unqualified visual loss' category 9.

If the extent of the visual field is taken into account, patients with a field no greater than 10 but greater than 5 around central fixation should be placed in category 3 and patients with a field no greater than 5 around central fixation should be placed in category 4, even if the central acuity is not impaired.

Category of visual impairment	Visual acuity with best possible correction
	Maximum less than:	Minimum equal to or better than:

	6/18	6/60
1	3/10 (0.3)	1/10 (0.1)
	20/70	20/200

	6/60	3/60
2	1/10 (0.1)	1/20 (0.05)

3	1/20 (0.05)	1/50 (0.02)
	20/400	5/300 (20/1200)

	1/60 (finger counting at one meter)	Light perception
