OBJETIVO: O objetivo deste estudo foi identificar potenciais marcadores prognósticos visuais em pacientes com hipertensão intracraniana idiopática (HII).
MÉTODOS: Pacientes com HII de um ambulatório de cefaleia em São Paulo, Brasil, foram avaliados retrospectivamente e divididos em dois grupos de acordo com a presença ou não de redução visual permanente atribuída a HII. O índice de massa corporal (IMC), a pressão de abertura do LCR e a frequência de anormalidades de RM relacionadas à HII foram comparados entre esses dois grupos.
RESULTADOS: Vinte e nove pacientes, com 35,39±9,93 anos, sendo vinte e oito do sexo feminino (96,55%), foram incluídos no estudo. A redução da acuidade visual atribuída à HII foi registrada em 16 (55,17%). De acordo com o IMC, 17,4% tinham sobrepeso e 82,6% eram obesos. A ressonância magnética cerebral foi normal em 6 (20,69%). O IMC, a frequência de obesidade e a frequência de anormalidades na RM relacionadas à HII não foram associados à deficiência visual. A pressão inicial de abertura do LCR inicial foi significativamente maior no grupo de pacientes com acuidade visual reduzida (40,4±13,14 x 30,5±3,41, P=0,015).
CONCLUSÃO: Os pacientes com deficiência visual permanente associada à HII tiveram maior pressão de abertura do LCR, sugerindo que esse parâmetro tenha potencial valor para a avaliação prognóstica destes pacientes.
