The aim of this paper is to report a case of unilateral idiopathic episcleral venous hypertension in a young woman and to describe the diagnostic procedure for this relatively rare condition. Treatments Contact lenses Corneal refractive surgery: The condition should be distinguished from other diseases, the most common of which is arteriovenous fistula, which can cause dilated episcleral vessels and elevated IOP.

There are rare cases of open-angle glaucoma and dilated episcleral veins without an apparent cause. Doppler ultrasound is a non-invasive method for examining the orbital and ocular blood flow and, in patients with fistula, it typically shows retrograde blood flow and a dilated superior ophthalmic vein campimetrua.
This flash of light appears in different zones of the visual field of the eye being examined. However, in this report, we chose to perform a computed tomography of the head and orbits and a Doppler ultrasound; as these icular showed no abnormalities, more invasive and complex diagnostic tests were deemed unnecessary. Arterio-venous fistula is the most oculaar cause of ocular hyperaemia with elevated IOP, due to episcleral venous hypertension 8,9.
