Nuestro objetivo en GRF es ayudar a encontrar una cura. 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 1.

Biomicroscopy of the RE was normal. Jorgensen and Guthoff, while studying 64 patients with glaucoma due to episcleral venous hypertension, diagnosed this syndrome in 10 patients 8.

There are rare cases of open-angle glaucoma and dilated episcleral veins without an apparent cause. In the ophthalmological examination, she presented dilated tortuous vessels in her left bulbar conjunctiva, very high intraocular pressure and increased cupping of the optic disc. The patient had a reduced direct photomotor reflex and a prominent relative afferent defect in the LE.

Thus, it was suggested the possibility of idiopathic elevated episcleral venous pressure, an exclusion diagnosis, since intra-cranial and intraorbital pathologies were excluded. Of the 25 cases reviewed in the English literature, 24 had an open angle, of which 13 had blood in Schlemm’s canal 1, Solicite su copia gratuita.

The episcleral venous pressure was measured and corresponded to twice the normal value in the affected eyes of these patients 4. When medical treatment is not sufficient, filtration surgery is the procedure of choice. Additionally, there are reports in the literature of choroidal effusion after filtration surgery, showing that the procedure is not without risks or complications 3.

Contrast Dark on Light Light on Dark. No relevant neurologic findings. Although the cause of this disorder remains unclear, a congenital abnormality in the vasculature and familial predisposition have been considered as possible causes 5.

Where the Money Goes. 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. Idiopathic dilated episcleral veins and increased intraocular pressure. However, because this is a rare condition, it is difficult to estimate the sensitivity of such tests.



These imaging tests are important because they can exclude other conditions. Episcleral venous hypertension is a diagnosis of exclusion that must be considered after intraorbital and intracranial conditions have been discarded. Jorgensen JS, Guthoff R.

Sin embargo, algunas personas pueden tener glaucoma con presiones de entre 12 y 22 mm Hg. Of the 25 cases reviewed in the English literature, 13 involved predominantly the RE, 3 involved predominantly the LE, and 9 had bilateral involvement, although asymmetrical.

Gonioscopy typically camlimetria an open angle, and blood may or may not be visible in Schlemm’s canal.

The diagnostic evaluation should include a complete eye examination and imaging. However, due to the risk of glaucomatous damage, we decided to proceed with trabeculectomy. The treatment of glaucoma due to idiopathic episcleral venous hypertension with elevated IOP is similar to primary open angle glaucoma 3. Dilated episcleral veins may occur unilaterally or bilaterally. Most cases of dilated episcleral veins with increased IOP can be attributed to carotid-cavernous fistula, cavernous sinus thrombosis, dural arterio-venous shunt, superior vena cava syndrome, Sturge-Weber syndrome, dysthyroid orbitopathy, obstructive orbital injuries, or orbital varices 2.

Idiopathic episcleral venous hypertension is a relatively rare syndrome that progresses with ocular hyperaemia and elevated IOP. Can we help you? Website Sponsors We appreciate support from corporations who believe in our mission to educate glaucoma patients and speed a cure.
