Central retinal artery occlusion (CRAO) is a devastating ocular emergency characterized by acute painless visual loss in the ipsilateral eye. We describe the case of acute non-arteritic CRAO associated fusiform internal carotid-ophthalmic artery aneurysm with intraluminal thrombus. Despite the rarity of this condition, we suggest that carotid-ophthalmic artery aneurysm should be included in the differential diagnosis of CRAO.

Anterior ischemic optic neuropathies (AIONs) represent a segmental infarction of the optic nerve head (ONH) supplied by the posterior ciliary arteries (PCAs). Blood supply blockage can occur with or without arterial inflammation. For this reason, there are two types of AIONs: non-arteritic (NA-AION), and arteritic (A-AION), the latter is almost invariably due to giant cell arteritis (GCA). GCA is a primary vasculitis that predominantly affects extracranial medium-sized arteries, particularly the branches of the external carotid arteries (including superficial temporal arteries - TAs)...

INTRODUCTION: Non-arteritic anterior ischemic optic neuropathy (NAION) is one of the most widespread visually disabling diseases in the middle-aged and elderly population. It typically presents as acute painless unilateral vision loss in patients over 50 years of age. The fellow eye of NAION patients is often sequentially affected. Involvement of the second eye occurs within three years in approximately 45%-50% of patients. Currently there is no generally accepted treatment for NAION but a number of medical and surgical therapies have been proposed...

A 21-year-old girl presented with acute painless vision loss in her right eye. There was no remarkable ocular history and she had a history of anorexia nervosa. At presentation best-corrected visual acuities were counting fingers from 2 meters and 20/20, in the right and left eyes, respectively. Slit lamp examination result was normal. Fundus examination revealed multiple cotton wool spots and intraretinal hemorrhages surrounding the optic disc and macula in the right eye. Fluorescein angiography showed capillary filling defect and leakage from optic disc in the late phase of the angiogram...

A 56-year-old man was referred to our hospital about 48 h after sudden onset of painless central visual loss in his right eye (OD) on a winter morning. He had a more than 25-year history of systemic hypertension and smoking. Funduscopic observation showed striated retinal whitening in the macular region, faint cotton-wool patches around the optic disc, and segmental narrowing of the retinal arteries near the optic disc edge. Based on the pattern of onset and fundus findings, he was diagnosed with vasospastic acute central retinal artery occlusion OD, and a venous drip injection of prostaglandin E1 was started immediately...

Acute lymphoblastic leukemia is a malignant hematopoietic neoplasia, which is rare in adults. Although ocular fundus alterations may be commonly observed in the course of the disease, such alterations are rarely the presenting signs of the disease. Here we describe the case of a patient with painless and progressive loss of visual acuity (right eye, 2/10; left eye, 3/10) developing over two weeks, accompanied by fever and cervical lymphadenopathy. Fundus examination showed bilateral macular serous detachment, which was confirmed by optical coherence tomography...

A 36-year-old woman presented with acute vision loss and was found to have disc oedema and retinitis pigmentosa (RP). She presented with a history of acute, painless vision loss in her left eye over a period of 10 days. Her best-corrected visual acuity was 20/50, N6 in the right eye (OD) and 20/160, N6 in the left eye (OS). She was found to have a swollen optic disc and the examination of her fundus showed changes suggestive of RP. The diagnosis of RP was confirmed by electroretinogram, and after ruling out demyelinating changes in the central nervous system and other possible infectious causes of papillitis, she was treated with intravenous steroids followed by a course of oral steroid therapy...

Non-arteritic anterior ischemic optic neuropathy is a result of an infarction of the small vessel at the anterior portion of the optic disc and causes acute, unilateral, painless visual loss. There is no generally accepted treatment method for this condition but some medical and surgical treatments are recommended. Earlier studies show that visual acuity recovery was better with corticosteroid medication compared to non-treated patients. However corticosteroids may cause side effects such as cataract, increased intraocular pressure and rarely central serous chorioretinopathy...

Cerebral venous sinus thrombosis (CVST) is not an uncommon cause of stroke but very often unrecognized at initial presentation due to lack of clinical suspicion and thus frequently left untreated. CVST is a potentially serious condition which manifests with diverse clinical manifestations, from isolated headache to focal neurological signs and even coma. CVST usually takes place either an inherited thrombophilia or any acquired hyperviscosity state and thus prompting anticoagulation was regimen as is the cornerstone of successful treatment...

We report a 53-year-old woman who had acute visual loss 10 days after cardiopulmonary cerebral resuscitation performance. Immediately after she had performed cardiopulmonary cerebral resuscitation, she developed floater symptoms in her left eye, which persisted for 2 hours, and she was diagnosed as having Valsalva retinopathy. Ten days later, she had an acute painless visual loss in the same eye (visual acuity 20/1000). On fundus examination, optic disk edema, peripapillary hemorrhage, and retinal artery occlusion were detected in the superior half of her left retina and she was diagnosed as having branch retinal artery occlusion...

Nonarteritic anterior ischaemic optic neuropathy (NAION) is the most common acute optic neuropathy in patients over the age of 50 and is the second most common cause of permanent optic nerve-related visual loss in adults after glaucoma. Patients typically present with acute, painless, unilateral loss of vision associated with a variable visual field defect, a relative afferent pupillary defect, a swollen, hyperaemic optic disc, and one or more flame-shaped peripapillary retinal haemorrhages. The pathogenesis of this condition is unknown, but it occurs primarily in patients with structurally small optic discs that have little or no cup and a variety of underlying vascular disorders that may or may not be known at the time of visual loss...
