| pectinate ligaments of iridocorneal angle | The network of fibres (pectinate ligaments) at the iridocorneal angle between the anterior chamber of the eye and the venous sinus of the sclera; it contains spaces between the fibres that are involved in drainage of the aqueous humor, and is composed of two portions: the corneoscleral part, the part attached to the sclera, and the uveal part, the part attached to the iris. Synonym: reticulum trabeculare sclerae, Gerlach's valvula, Hueck's ligament, ligamentum annulare bulbi, pectinate ligaments of iridocorneal angle, pillar of iris, trabecular meshwork, trabecular network, trabecular zone.

| pelvivertebral angle | The angle made by the pelvis as defined by the plane of the superior pelvic aperture with the general axis of the trunk or vertebral column. See: inclination of pelvis. (05 Mar 2000) |

| cerebellopontine angle syndrome | <syndrome> A syndrome due most commonly to an acoustic tumour in the region between the cerebellum and pons, and marked by ataxia, nystagmus, tinnitus, deafness, disturbances of labyrinth function, and involvement of any of the cranial nerves, fifth, sixth, seventh, ninth, or tenth.

| cerebellopontine angle tumour | This is a benign tumour of the 8th cranial nerve that affects approximately 1 out of 100,000 people. This tumour arises from the myelin forming Schwann cells that coat the 8th cranial nerve (acoustic nerve). Clinical presentation usually includes hearing deficit. Diagnosis can be made with auditory evoked potentials and/or MRI scanning of the brain. Vertigo and tinnitus may be associated symptoms. Surgical removal of this tumour involves dissection, cautery and obliteration with laser. Causes: acoustic neuroma (90%), meningioma (7%), epidermoid (3%), uncommon: metastasis, trigeminal neuroma, arachnoid cyst, aneurysm, vertebro-basilar dolichoectasia (12 Dec 1998) |
