Diagnosis is based on the presence of dilated episcleral vessels, elevated IOP, and open angle on gonioscopy. Arterio-venous fistula is the most frequent cause of ocular hyperaemia with elevated IOP, due to episcleral venous hypertension 8,9. The treatment of glaucoma due to idiopathic episcleral venous hypertension with elevated IOP is similar to primary open angle glaucoma 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.
Sin embargo, algunas personas pueden tener glaucoma con presiones de entre 12 y 22 mm Hg. She was overweight with a history of dyslipidemia and was seeing an endocrinologist. This condition is known as idiopathic episcleral venous hypertension 1, 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.
However, due to the risk of glaucomatous damage, we decided to proceed with trabeculectomy.

For medical questions and advice specific to your condition, please contact your doctor. Dilated episcleral veins may occur unilaterally or bilaterally. 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.
These imaging tests are important because they can exclude other conditions. Older reports mention the use of the MRI in a few cases, and although this is a more sensitive test than CT, it yielded no major findings, with most cases showing no abnormalities 3. No prior preparation is required on the part of the patient for this kind of study, which is entirely painless and has no side effects. The onset of signs dilated episcleral vessels may vary, usually occurring between the third and fourth decades of life 3.

Camplmetria Newsletter Stay up-to-date with the latest news about glaucoma, treatments, and research. Although the cause of this disorder remains unclear, a congenital abnormality in the vasculature and familial predisposition have been considered as possible causes 5.
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. The intraocular pressure IOP depends on the rate of production of aqueous humour, the ease of its drainage and episcleral venous pressure 1.
There are rare cases of open-angle glaucoma and dilated episcleral veins without an apparent cause.
The ocular findings in carotid-cavernous fistula in a series of 17 cases. Given the very campimeyria IOP values in the LE, we opted for medical treatment with hypotensive eyedrops timolol maleate, brimonidine tartrate, dorzolamide hydrochloride and travoprost. Thus, it was suggested the possibility of idiopathic elevated episcleral venous pressure, an exclusion diagnosis, since intra-cranial and intraorbital pathologies were excluded.

Computed tomography of the brain and orbits was within normal limits, as well as Doppler ultrasound of the eyeballs Figure 2. Website Sponsors We appreciate support from corporations who believe campiketria our mission to educate glaucoma patients and speed a cure.
Measuring episcleral venous pressure is unpractical, with no commercially-available instruments to this end 3.
Biomicroscopy of the RE was normal. Revista Brasileira de Oftalmologia. The patient had a reduced direct photomotor reflex and a prominent relative afferent defect in the LE. Campiemtria condition should be distinguished from other diseases, the most common of which is arteriovenous fistula, which can cause dilated episcleral vessels and elevated IOP. One report mentions a patient who underwent trabeculectomy with subsequent reduction of the IOP, although the episcleral vessels remained dilated 6.
Laboratory tests thyroid hormones, rheumatologic tests, coagulation, serology for infectious diseases showed no relevant findings.
Blood in Schlemm’s canal is a general sign of episcleral venous hypertension, but it is not always present, as was the case with our patient and other cases in the literature 3. 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.
