Diabetic and Retinal Vascular Eye Disease.

Med Clin North Am 2021 May 2;105(3):455-472. Epub 2021 Apr 2.

John A. Moran Eye Center, 65 North Mario Capecchi Drive, Salt Lake City, UT 84132, USA.

The retinal vasculature is the only neurovascular system directly visible to the human eye, easily evaluated by fundoscopy and many imaging modalities. This window allows physicians to diagnose and treat retinal pathologies and detect systemic diseases including diabetes, hypertension, hypercoagulable/hyperviscosity syndromes, and vasculitis. Diabetic retinopathy is the most common retinal vascular disease, followed by retinal vein and artery occlusion. Read More

Cilioretinal Artery Occlusion after Endovascular Coil Embolization for Anterior Communicating Artery.

Brain Sci 2021 Apr 25;11(5). Epub 2021 Apr 25.

Department of Neurology, Veterans Health Service Medical Center, 53 Jinhwangdo-ro 61-gil, Gangdong-gu, Seoul 05368, Korea.

Unruptured intracranial aneurysms have a risk of rupture, so coil embolization is widely practiced as it preserves a patent artery. There are complications of coil procedures, such as patent artery occlusion and thromboembolism, which can result in retinal artery occlusion. We report onretinal artery occlusion following coil embolization of anterior communicating artery aneurysm. Read More

Histological Assessment of Rat Retinas with Ischemia-Reperfusion Injury.

Eur Surg Res 2021 Apr 29:1-7. Epub 2021 Apr 29.

Department of Surgery, Radiology, and Physical Medicine, University of The Basque Country, Leioa, Spain.

Introduction: Retinal ischemia-reperfusion (IR) injury occurs in pathological situations that interrupt the blood flow to the retina, such as is the case during central retinal artery occlusion (CRAO). The animal models described in the literature are based on the pressure produced by the weight of a given quantity of saline elevated to a certain height; however, to establish these parameters it is necessary to perform mathematical calculations that cannot be easily redone in the case of punctual variations of intraocular pressure (IOP). The aim of this study was to present a new system that allows us to reproduce the conditions of retinal IR and thereby properly assess the level of injury in retinal histological samples. Read More

Eye Clinic, ASST Santi Paolo e Carlo Hospital, Università degli Studi di Milano, Milan, Italy.

Electrical stimulation (ES) of the eye represents a therapeutic approach in various clinical applications ranging from retinal dystrophies, age-related macular degeneration, retinal artery occlusion and nonarteritic ischemic optic neuropathy. In clinical practice, ES of the eye is mainly performed with a transcorneal or transpalpebral approach. These procedures are non-invasive and well-tolerated by the patients, reporting only minimal and transient adverse events, while serious adverse effects were not observed. Read More

Multimodal Imaging in Susac Syndrome: A Case Report and Literature Review.

Int J Environ Res Public Health 2021 03 26;18(7). Epub 2021 Mar 26.

Siena Crosslinking Center, 53100 Siena, Italy.

Susac syndrome (SS) is a rare microangiopathy that involves arterioles of the brain, retina, and cochlea. Diagnosis is extremely difficult because of the rarity of the disease and because the signs and symptoms often occur at different times. Multidisciplinary approaches and multimodal images are mandatory for diagnosis and prompt therapy. Read More

Cytotoxicity of β-Cyclodextrins in Retinal Explants for Intravitreal Drug Formulations.

Molecules 2021 Mar 9;26(5). Epub 2021 Mar 9.

Faculty of Pharmaceutical Sciences, University of Iceland, Hofsvallagata 53, IS-107 Reykjavik, Iceland.

Cyclodextrins (CDs) have been widely used as pharmaceutical excipients for formulation purposes for different delivery systems. Recent studies have shown that CDs are able to form complexes with a variety of biomolecules, such as cholesterol. This has subsequently paved the way for the possibility of using CDs as drugs in certain retinal diseases, such as Stargardt disease and retinal artery occlusion, where CDs could absorb cholesterol lumps.

The use of multimodal imaging in the evaluation of a patient with central retinal artery occlusion in the setting of asteroid hyalosis: a case report.

J Med Case Rep 2021 Apr 2;15(1):145. Epub 2021 Apr 2.

Department of Ophthalmology, Feinberg School of Medicine, Northwestern University, 645 N. Michigan Ave. Suite 440, Chicago, IL, 60611, USA.

Background: A central retinal artery occlusion (CRAO) is an ophthalmic emergency due to its strong association with cerebrovascular and cardiovascular morbidity and mortality. A timely diagnosis is necessary but difficult in the setting of dense asteroid hyalosis, as typical fundoscopic findings can be obscured. We present a case where multimodal imaging in an eye with an obscured fundus could lead to timely diagnosis and management of CRAO in a patient with acute vision loss. Read More
