  abstract = {{O}bjectives {V}isual impairment and cognitive disorders are common among older people in {L}ow-and {M}iddle-{I}ncome {C}ountries ({LMIC}). {S}everal recent studies performed in {H}igh-{I}ncome {C}ountries suggested that visual impairment is associated with cognitive disorders. {H}owever, no synthesis of current knowledge exists for {LMIC}. {M}ethods {W}e have conducted an extensive literature search combining six databases and two grey literature databases. {W}e searched for studies assessing the link between visual and cognitive impairments carried out in {LMIC}. {T}he systematic search was performed up to 14th {F}ebruary 2019. {R}esults {O}verall, eight studies were included in this review. {A}mong them, five studies were performed in {A}sia and seven studies had a cross-sectional design. {M}ean age of the participants varied from 64.2 to 76.2 years. {P}articipants were most often females. {O}nly three studies were specifically focused on the association between visual impairment and cognitive disorders. {O}ut of the eight studies included, four reported a significant association; two showed a possible association and two did not retrieve any statistically significant effect. {H}eterogeneity in assessments of visual and cognitive impairments was high. {C}onclusion {I}n {LMIC}, very few studies explored the association between visual and cognitive impairments among older people. {T}he current review seems to suggest that visual impairment is associated with cognitive disorders in {LMIC}. {H}owever, further studies are required to improve the knowledge on this relationship. {I}mproving vision, in particular through optical correction and cataract surgery, could potentially be easy pathways to reduce cognitive disorders incidence and to improve quality of life of people affected by this disorder.},
