[Catastrophic expenditure in children with visual impairment: a cross-sectional study with caregivers in Rio de Janeiro, Brazil].

Caring for a visually impaired child can affect the caregiver's income and, in turn, the family's. Catastrophic spending resulting from increased expenses and reduced income must be taken into account, whether due to unemployment, a reduction in the number of hours worked or the difficulty of entering or reentering the job market. Given this scenario, the main objective of this study was to estimate the catastrophic spending attributed to the caregiver of blind or low-vision children in reference centers for education for the blind, ophthalmology and child health located in the city of Rio de Janeiro, Brazil, identifying which factors are associated with a higher or lower prevalence of this expenditure. It was found that 53.3% of care for blind children involved 40% or more of their income. Among the caregivers of children with low vision, catastrophic spending is milder, compromising at least 40% of income for 36.8% of the caregivers. The factors associated with a higher prevalence of catastrophic spending were the caregiver's age, the number of residents in the household, higher schooling, lower household income, renovations to the home, health insurance, taking out loans, selling assets, the number of health units where the child receives treatment and the relationship of the main caregiver. The burden placed on caregivers of visually impaired children indicates a situation of vulnerability that shows the need for access to financial and social protection mechanisms, through policies that are capable of serving this group.
