Posterior Ischemic Optic Neuropathy

Purpose: To report on posterior ischemic optic neuropathies, a vascular disorder that happens in the posterior part of the optic nerve and therefore, usually does not present with optic disc edema. Case Report: This is a case report on a posterior ischemic optic neuropathy with an uncharacteristic presentation. It highlights the importance of understanding the different pathophysiology of PION vs anterior ischemic optic neuropathies in order to help differentiate the two clinically and includes a literature review of posterior ischemic optic neuropathy.

Introduction: Optic disc edema can be a manifestation of various neurological disorders. Identification of those causes is possible in most cases using tests like visual acuity, color vision, visual field and suitable radiological imaging. Study in Nepalese population with regard to optic disc edema is scarce. Hence this study aims to act as a guideline for evaluation of such cases and help in further studies in this regard. Methods: A descriptive, cross-sectional study was conducted in all cases of optic disc edema presenting to neuro-ophthalmology clinic of B.P. Koirala Lions Centre for Ophthalmic Studies from January 2011 to June 2012. A detailed history was obtained and proper ocular and nervous examination was done by ophthalmologist and neuro-physician. Assessment of visual acuity, color vision, contrast sensitivity and visual field along with radiological tests were done in all possible cases. Results: Out of all the cases evaluated, 38 cases where causes of optic disc edema could be established were included in the study. The commonly affected age group was 31 to 40 years (26.3%) and most of them were males. The commonest cause observed was optic neuritis (36.8%). Others were papilledema, idiopathic intracranial hypertension, toxic optic neuropathy, non-arteritic anterior ischemic optic neuropathy (NA-AION), compressive and traumatic optic neuropathy. Conclusion: Optic neuritis and papilledema should be considered as common differential diagnosis in patients with optic disc edema. NA-AION is a relatively uncommon disease among Nepalese population.

Ipsilateral Recurrence

Nonarteritic anterior ischemic optic neuropathy (NA-AION) is a multifactorial disease that represents the most common type of ischemic optic neuropathy. NA-AION develops in one eye and can occur in the fellow eye at a later date.1The recurrence of ipsilateral NA-AION is rare and a multitude of theories have arisen to explain this infrequent recurrence.2 This case report describes an incident of unilateral recurrence of NA-AION, explores the proposed etiologies, and will emphasize visual symptoms following its resolution.   Key words.  optic nerve edema  Ÿ  recurrent Ÿ nonarteritic ischemic optic neuropathy Ÿ contrast sensitivity  Ÿ  peripapillary retinal nerve fiber layer (pRNFL)

A 69-years-old male patient was treated with amiodarone 200mg/day over the passed two months for atrial fibrillation. He presented a sudden, painless and unilateral visual loss. Ophthalmologic evaluation revealed a bilateral optic disc edema. Neurological examination was otherwise unremarkable. After properly excluding increased intracranial pressure and giant cell arteritis, the main differential diagnosis was between nonarteritic anterior ischemic optic neuropathy and optic neuropathy secondary to amiodarone. The latter diagnosis was favored due to a presence of bilateral and simultaneous optic disc edema, gradual improvement of symptoms after discontinuation of the drug, and, mostly, by persistence of optic disc edema beyond 6 weeks. Of note, an acute presentation of this disorder is common. Amiodarone optic neuropathy is a rare but potentially serious cause of optic nerve dysfunction, and its discontinuation is usually warrant.

Disc Edema

A 70-year-old woman with metastatic small-cell lung cancer was referred for isolated left optic disc edema that was incidentally discovered. She had normal visual function, and dilated fundus examination revealed a small, cupless optic nerve in the right eye and moderate optic disc edema in the left eye. Magnetic resonance imaging (MRI) of the orbits with contrast was normal, and MRI brain and magnetic resonance venography were normal without signs of raised intracranial pressure. Lumbar puncture showed a normal opening pressure and normal cerebrospinal fluid contents. A diagnosis of incipient non-arteritic anterior ischemic optic neuropathy (NAION) was made, and the optic disc edema resolved after 4 months. Incipient NAION is an uncommon cause of unilateral optic disc edema with preserved visual function and is a diagnosis of exclusion. In diagnosing incipient NAION, other causes of optic disc edema must first be ruled out. These alternative causes include papilledema, optic nerve sheath meningioma or other orbital masses, and vitreopapillary traction. Incipient NAION is thought to be caused by subclinical ischemia. This case indicates that incipient NAION may also occur in patients with metastatic cancer and is possibly related to their hypercoagulable state. Although there is no treatment once vision loss develops, the optimization of risk factors may prevent the progression of incipient NAION to classic NAION.
