purpose: to compare repeated intravitreal injections of bevacizumab (ivb) with triamcinolone acetonide (ivt) for treatment of acute branch retinal vein occlusion (brvo). methods: this randomized clinical trial included, 86 eyes with recent onset (less than 12 weeks) brvo. participants were randomly assigned to two treatment groups: the ivb group (43 eyes) consisted of patients who received mont...

The authors report a case of a patient with coronary insufficiency who developed central retinal artery occlusion following cardiac catheterism through the brachial artery and cineangiocoronography. This procedure can lead to embolic phenomena like that which was reported.

A retrospective, single-center review from January 2017 to August 2020. Of 91 patients with acute nonarteritic central retinal artery occlusion, >50% ipsilateral internal carotid (ICA) stenosis was present in about one quarter of patients. Approximately 30% who had been receiving at-home antiplatelet therapy or anticoagulation at symptom onset were treated an increase dosage, and 80% not antico...

Central retinal artery occlusion (CRAO) is one of the most devastating ophthalmic emergencies, causing acute painless visual loss in the affected eye. We describe the first case of acute non-arteritic CRAO associated with peripheral ophthalmic artery aneurysm and its clinical course after intra-arterial thrombolysis therapy. This case suggests that ophthalmic artery aneurysm can be the cause of...

BACKGROUND Full field and pattern electroretinograms (ERG, PERG) are performed to assess generalised retinal function and macular function, respectively. An (electro) negative full field ERG usually describes an ISCEV standard maximal response in which the b-wave is smaller than a normal or minimally reduced a-wave and indicates dysfunction that is post-phototransduction. The most common cause ...

Retinal ischemia is a frequent source of irreparable visual impairment and even loss of sight, affecting over a hundred million individuals in the world. It is associated with a wide range of clinical retinal disorders, like ischemic optic neuropathies, obstructive retinopathies, carotid occlusive disorders, diabetic retinopathy and glaucoma. Retinal ischemia occurs when the blood supply to ret...

BACKGROUND Retinal artery occlusion caused by myxoma is relatively rare. There are several points that should be taken into consideration to avoid overlooking this disorder. CASE PRESENTATION This case report describes a 43-year-old woman with sudden vision loss in her left eye for 20 days after single sudden syncope. Fundus examination of the left eye showed obscure boundary of optic disc wi...

A 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. Slit lamp examination showed arborizing conjunctival vessels and dry eye. Fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. Cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. An ascert...
