Use of Fluorescence Fundus Angiography to Assess Variations in Retinal Circulation in Myopic Patients of Different Ages

Abstract

To investigate the variation in retinal circulation in patients with different degrees of myopia and different age by fluorescence fundus angiography (FFA). Thirty myopic patients (60 eyes), 20–54 years of age, with various degrees of myopia were evaluated. All patients underwent fundus photography and FFA using a standard technique. Patients with other ophthalmologic diseases possibly affecting the retrobulbar circulation and those with a history of laser treatment or intraocular surgery were excluded. Vascular filling patterns at arterial phase, arterial-venous phase and venous phase were reviewed. The average filling times at each phase were significantly delayed in severe myopia, but there was no difference between eyes with mild and medium myopia. There was no statistically significant correlation between mean filling time and age. The findings indicated a significant correlation between the intraocular blood circulation and the degree of myopia.
