Optical coherence tomography angiography (OCT‐A) is a non‐invasive imaging modality for assessing the vasculature within ocular structures including retina, macula, choroid and optic nerve. OCT‐A has wide range of clinical applications in various optometric conditions which have been independently reported literature. This paper aims to present review current literature on application practice ...

Central retinal arterial occlusion is an ocular emergency. Central retinal artery occlusion following cardiac procedures have been described in adults. We describe a pediatric patient who developed central retinal artery occlusion following pulmonary artery stenting. It is important to highlight this potential risk to ensure early diagnosis and prompt treatment.

Retinal image processing is a standard medical repetition and offers number of profitable products for physicians. In the field of retinal image processing retinal vessel segmentation is the crucial task for detection of cardiovascular diseases in advance. The recognition of erroneous blood vessel may cause in incorrect clinical diagnosis. Various processing steps are required for the extractio...

BACKGROUND Dengue virus infection is on the rise and there is increasing number of ocular complications that are being reported. Most common ocular complications are macular edema, macular hemorrhages, and foveolitis. There are case reports on branch retinal vessel occlusions. Most of the ocular complications are attributed to the bleeding tendency and transudative process in dengue viral infec...

We developed a new surgical treatment in which a microneedle is used for retinal endovascular cannulation to treat eyes with central retinal vein occlusion by flushing thrombus out of the central retinal vein as it passes through the lamina cribrosa. The eyes of 12 consecutive patients (12 eyes) with central retinal vein occlusion were successfully treated using this novel treatment. At 24 week...

Angiogenesis is the process by which new blood vessels form from existing vessel networks. In the past three decades, significant progress has been made in our understanding of angiogenesis; progress driven in large part by the increasing realization that blood vessel growth can promote or facilitate disease. By the early 1990s, it had become clear that the recently discovered "vascular endothe...

This paper reports the histopathological findings in the eyes of a 26-year-old female patient diagnosed with systemic lupus erythematosus (SLE) with peripheral neuropathy. The patient had no significant ocular problems. She died of pneumonia after two years of suffering. The eyeballs were procured at autopsy and the retina, choroid and optic nerve processed for light and electron microscopy, an...

Background. Giant cell arteritis (GCA) is a systemic granulomatous vasculitis that affects large- and medium-sized arteries of the head and neck. Ocular manifestations of GCA usually are anterior ischaemic optic neuropathy (AION) or retinal vessel occlusion. Case Report. We report an interesting case of a 70-year-old man who presented with sudden vision loss and choroidal infarction in his left...

Central retinal artery occlusion (CRAO) is an of the central that causes a disruption blood flow to retina and may result in ischemia. According American Heart Association/American Stroke Association (AHA/ASA), CRAO type acute ischemic stroke. There some variation management. Determining most effective therapy remains challenging. We report male, 58th-years-old, with sudden vision loss right ey...
