!markdown The table below gives a classification of severity of vision impairment recommended by the Resolution of the International Council of Ophthalmology (2002) and the Recommendations of the WHO Consultation on “Development of Standards for Characterization of Vision Loss and Visual Functioning" (September 2003) For characterizing binocular vision impairment, vision acuity should be measured with both eyes open with presenting correction if any. For characterizing monocular visual impairment, visual acuity should be measured monocularly with presenting correction if any. If the extent of the visual field is taken into account, patients with a visual field of the better eye no greater than 10° in radius around central fixation should be placed under ‘inocular’. For monocular blindness, this degree of field loss would apply to the affected eye. +:--------------------------------+:-------------------------------------------------+:-----------------------------+ |**Category** |**Presenting distance visual acuity** | | |**Worse than:** | **Equal to or better than:** | +=================================+==================================================+==============================+ | | | 6/12 \\| | 0 No vision impairment | | 5/10 (0.5) \\| | | | 20/40 | +---------------------------------+--------------------------------------------------+------------------------------+ | | 6/12 \\| 6/18 \\| | 1 Mild vision impairment | 5/10 (0.5) \\| 3/10 (0.3) \\| | | 20/40 | 20/70 | +---------------------------------+--------------------------------------------------+------------------------------+ | | 6/18 \\| 6/60 \\| | 2 Moderate vision impairment | 3/10 (0.3) \\| 1/10 (0.1) \\| | | 20/70 | 20/200 | +---------------------------------+--------------------------------------------------+------------------------------+ | | 6/60 \\| 3/60 \\| | 3 Severe vision impairment | 1/10 (0.1) \\| 1/20 (0.05) \\| | | 20/200 | 20/400 | +---------------------------------+--------------------------------------------------+------------------------------+ | | 3/60 \\| 1/60\\* \\| | 4 Blindness | 1/20 (0.05) \\| 1/50 (0.02) \\| | | 20/400 | 5/300 (20/1200) | | 6 Blindness | No light perception | or counts fingers (CF) | | | | at 1 metre | +---------------------------------+--------------------------------------------------+------------------------------+ | | 1/60\\* \\| | | 5 Blindness | 1/50 (0.02) \\| Light perception | | | 5/300 (20/1200) | | +---------------------------------+--------------------------------------------------+------------------------------+ | 6 Blindness | No light perception | | +---------------------------------+--------------------------------------------------+------------------------------+ | 9 | Undetermined or unspecified | | +---------------------------------+--------------------------------------------------+------------------------------+ |**Category** | **Presenting near visual acuity** | | +---------------------------------+--------------------------------------------------+------------------------------+ | | Worse than N6 or M 0.8 with existing correction | +---------------------------------+--------------------------------------------------+------------------------------+ |
