Health-related quality of life of children with vision impairment or blindness.

The aims of the study were to describe the functional ability, health status, and health-related quality of life (HRQL) of young children with a vision impairment or blindness (VI/BL) and to examine the effect of different types of ophthalmic condition and the presence of other impairments or systemic disorders. A cross-sectional community survey of children aged 3 to 8 years with VI/BL was conducted in four areas of England using the Health Utilities Index Mark 3 system. Seventy-nine children (47 males, 32 females; mean age 6 y 2 mo [SD 1 y 6 mo]) met the selection criteria: 43% had a visual pathway condition, 38% a condition of the eye, and 19% nystagmus alone; and 61% had additional impairments/disorders. Eighty per cent had functional limitations on at least two of the following attributes: vision, hearing, speech, cognition, ambulation, dexterity, emotion, and pain. Forty-four per cent had functional limitations on four or more attributes. Children with nystagmus alone had significantly higher mean HRQL utility scores (0.80 [SD 0.26]) than children with a condition of the eye (0.45 [SD 0.33]), who, in turn, had higher scores than children with a visual pathway condition (0.05 [SD 0.33], p=0.002). Children with an isolated VI/BL had significantly higher mean scores (0.73 [SD 0.21]) than those with additional impairments/disorders (0.09 [SD 0.34], p<0.001). These findings underline the need for a broad assessment of each child with VI/BL and a multidisciplinary approach to care.
