Retinopatia hipertensiva é a apresentação ocular mais comum da hipertensão. As alterações arterioscleróticas da retinopatia hipertensiva são causadas pela pressão arterial cronicamente elevada._x000D_ A retinopatia hipertensiva inclui 2 processos patológicos: os efeitos agudos e os crônicos. Os efeitos agudos da hipertensão arterial sistêmica são um resultado do vasoespasmo para autorregular a perfusão. Os efeitos crônicos da hipertensão são causados pela arteriosclerose e predispõem os pacientes a perda visual a partir de complicações de oclusões vasculares ou macroaneurismas. | |||
