data suggest that the multifocal electroretinography (mferg) may have a role in the assessment of patients with central retinal vein occlusion (crvo). to explore the mferg responses in patients with crvo. mferg responses were recorded at 61 discrete retinal locations from both eyes of 25 patients diagnosed with retinal vein occlusions within 3 weeks of onset. the latencies and amplitudes of ave...

Carotid stump syndrome (CSS) is known to be one of the causes of recurrent ipsilateral ischemic stroke following the occlusion of the internal carotid artery (ICA). The present study describes a case of left CSS in a 50-year-old patient presenting with a central retinal artery embolism following internal carotid and middle cerebral artery occlusion. The central retinal artery embolism was belie...

Central retinal artery occlusion is a rare event and the site of obstruction is not usually visible on clinical examination; therefore, the precise cause is often speculative. It is currently believed that the majority of central retinal artery obstruction is caused by thrombus formation. Atherosclerosis is implicated as the contributory event in most cases, although congenital anomaly of the c...

The hypothesis that an occlusion of the central retinal artery is an essential prerequisite for haemorrhage formation after central retinal vein obstruction has been investigated by examining the fundus changes in patients with a cilio-retinal arterial circulation; the findings are at variance with the 'combined occlusion hypothesis'. Comparisons were made between the pathological features in t...

central retinal vein occlusion (crvo) is the third most common blinding vascular retinal disorder. as there is no proven treatment for crvo, we performed this study to evaluate the effectiveness of radial optic neurotomy (ron) on visual acuity in eyes with crvo. this study was designed as an interventional case series. pars plana vitrectomy with ron was performed in 18 eyes of 16 patients with ...

Vitrectomy With Intrasurgical Control of Ocular Hypotony as a Treatment for Central Retina Artery Occlusion Central retinal artery occlusion (CRAO) is an ocular emergency usually caused by blockage of a vessel by a thrombus or embolus. The central retinal artery supplies the inner two thirds of the retina; the occlusion of this vessel causes ischemia and subsequent necrosis. Experimental studie...

BACKGROUND Postoperative vision loss following routine nasal surgery is an extremely rare and devastating complication. We report a case of unilateral blindness due to central retinal artery occlusion associated with third cranial nerve following septoplasty. CASE REPORT We report a patient who developed an unusual central retinal artery occlusion with unilateral blindness following nasal sur...

A case of central retinal artery occlusion in a patient with a 10-year history of unexplained thromboembolic disease due to a secondary hypercoagulable state is presented. Ophthalmological examination led to the final diagnosis.

Central retinal artery occlusion (CRAO) is an uncommon entity in ophthalmic practice. Reported etiologies are numerous, and involve systemic and ocular preexisting pathologies. A traumatic etiology for CRAO is rare with anecdotal reports and poor visual outcomes. No specific treatment guidelines exist to date. We report a case of traumatic CRAO in a young female without any systemic vascular ri...

PURPOSE The aim of this study was to determine whether a significant correlation exists between the scotopic and photopic components of electroretinograms (ERGs) and the degree of circulation disturbances caused by a central retinal artery occlusion (CRAO). DESIGN Observational clinical study. PARTICIPANTS Sixteen patients with a CRAO (16 eyes). METHODS The circulatory disturbance in eyes...
