Intermittent retinal artery occlusions as the first clinical manifestation of polycythemia vera: a case report.

BMC Ophthalmol 2022 May 15;22(1):221. Epub 2022 May 15.

Department of Ophthalmology and Optometry, Medical University Innsbruck, Anichstrasse 35, 6020, Innsbruck, Austria.

Bilateral blindness in a young male of rhino-orbital-cerebral mucormycosis: A case report.

Indian J Ophthalmol 2022 05;70(5):1822-1824

Department of Radio-Diagnosis, Adesh Institute of Medical Sciences and Research, Bathinda, Punjab, India.

The storm of COVID-19-associated mucormycosis (CAM) has not yet settled, and it has proven itself a disfiguring and potentially life-threatening disease, complicating the course of COVID-19 infection. Mucormycosis is a rare but devastating fungal infection caused by filamentous fungi of the family Mucoraceae. We report a rare case of a 37-year-old diabetic male with bilateral rhino-orbital-cerebral mucormycosis (ROCM) where it leads to bilateral central retinal artery occlusion (CRAO) as manifestation of the disease.

Central Retinal Artery Occlusion Is Related to Vascular Endothelial Injury and Left Ventricular Diastolic Dysfunction.

J Clin Med 2022 Apr 18;11(8). Epub 2022 Apr 18.

Jagiellonian University Medical College, Department of Internal Medicine, Faculty of Medicine, 31-066 Cracow, Poland.

Central retinal artery occlusion (CRAO) is an emergency state characterized by sudden, painless vision impairment. Patients with CRAO have an increased risk of cardiovascular events, including stroke, likely related to vascular endothelial damage. Therefore, we investigated flow-mediated dilatation (FMD) of the brachial artery as a marker of endothelial dysfunction, intima-media complex thickness (IMT) of the common carotid artery, pointing to the arterial wall atherosclerotic alteration, and transthoracic echocardiographic parameters in 126 consecutive CRAO patients (66 men [52.

Unilateral branch retinal artery occlusion in a patient with systemic lupus erythematosus: A case report.

Medicine (Baltimore) 2022 Mar 11;101(10):e29005. Epub 2022 Mar 11.

Department of Ophthalmology, Foshan Second People's Hospital, 78 Weiguo Road, Chancheng District, Foshan, Guangdong Province, China.

Rationale: Ocular involvements in systemic lupus erythematosus (SLE) are not rare but extremely varied. Here we present a very meaningful case with unilateral branch retinal artery occlusion (BRAO) secondary to undetected SLE, for which immunotherapy showed significant effect, which led to complete resolution of macular edema.

Patient Concerns: A 31-year-old female patient, so far without any previous illnesses, presented with a sudden onset of painless diminution of vision in left eye for 5 days. Read More

Transluminal Nd: YAG laser embolysis for branch retinal artery occlusion: Case report.

Medicine (Baltimore) 2022 Mar 11;101(10):e27984. Epub 2022 Mar 11.

Department of the Ophthalmology, Beijing Tongren Eye Hospital, Capital Medical University, Beijing, China.

Rationale: Central retinal artery occlusion and branch retinal artery occlusion (BRAO) result in partial or complete retinal ischemia and sudden loss of vision; to date there is no effective therapy for central retinal artery occlusion and BRAO. Transluminal Nd:YAG laser embolysis (TYE) could represent a therapeutic approach for retinal vascular occlusive diseases.

Patient Concerns: We report 2 cases with BRAO, 1 with inferor-temporal and 1 with superor hemiretinal BRAO. Read More
