Arterio-venous fistula is the most frequent cause of ocular hyperaemia with elevated IOP, due to episcleral venous hypertension 8,9. Diagnosis is based on the presence of dilated episcleral vessels, elevated IOP, and open angle on gonioscopy. The diagnosis of glaucoma secondary to idiopathic episcleral venous hypertension is clinical.
Fundus examination was normal in the RE, and the LE had a pale optic disc, with total excavation and discrete retinal venous dilation Figure 1. We appreciate support ocu,ar corporations who believe in our mission to educate glaucoma patients and speed a cure. Unilateral open-angle glaucoma secondary to idiopathic dilated episcleral veins. In another report of six patients with unilateral dilated episcleral veins and one patient with bilateral involvement, the IOP of affected eyes ranged from 21 to 44 mmHg 4.

Gonioscopy campimertia shows an open angle, and blood may or may not be visible in Schlemm’s canal. The treatment of glaucoma due to idiopathic ocukar venous hypertension with elevated IOP is similar to primary open angle glaucoma 3. Of the 25 cases reviewed in the English literature, 24 had an open angle, of which 13 had blood in Schlemm’s canal 1, Given the very high IOP values in the LE, we opted for medical treatment with hypotensive eyedrops timolol maleate, brimonidine tartrate, dorzolamide hydrochloride and travoprost.
The episcleral venous pressure was measured and corresponded to twice the normal value in the affected eyes of these patients 4. Los chequeos habituales del glaucoma incluyen dos pruebas de ojos de rutina: Please enter your question in the Campimetia box below.
She reported mild hyperaemia in the left eye starting eight years earlier.

There are rare cases of open-angle glaucoma and dilated episcleral veins without an apparent cause. There is some variability in the clinical presentation of episcleral venous hypertension. 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.
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.
Send this article to a friend by filling out the fields below: In the six patients with unilateral involvement, the IOP was higher in those eyes with dilated conjunctival vessels. The onset of signs dilated episcleral vessels may vary, usually occurring between the third and fourth decades of life 3.
The objective is to report a 33 year old female who came to the emergency room of Ophthalmology complaining of reduced visual acuity on the left eye, in a progressive and insidious way, about two years ago. The same procedure is then repeated for the other eye. Idiopathic episcleral venous hypertension is a relatively rare syndrome that progresses with campimetri hyperaemia and elevated IOP.
Episcleral venous hypertension is a diagnosis of exclusion that must be considered after intraorbital and intracranial conditions have been discarded. Laboratory tests thyroid hormones, rheumatologic tests, coagulation, serology for infectious diseases showed no relevant findings. No se preocupe si hay una demora campimetriia ver la luz a medida que se mueve hacia su punto ciego o alrededor.
Translational research in regenerative oculra cell therapies for retinal degenerative diseases: In this kind of examination, patients sit in front of the campimeter a device that is spherical on the inside. Extrinsic ocular motility was preserved. Measuring episcleral venous pressure is unpractical, with no commercially-available instruments to this end 3. Thanks to this examination, any kind of loss of periphery vision can be detected, as well as providing a map of this loss, which can guide and improve the diagnosis of certain pathologies glaucoma, retina disorders, damage in the optic tract, etc.
This campiemtria is known as idiopathic episcleral venous hypertension 1, Thus, it was suggested the possibility of idiopathic elevated episcleral venous pressure, an exclusion diagnosis, oculaf intra-cranial and intraorbital pathologies were excluded.
