microaneurysms

microaneurysms

1. Minute, but dangerous, widenings (dilatations) of arteries often in the brain, in the region of the THALAMUS, believed to be an important cause of CEREBRAL HAEMORRHAGE. These are distinct from the berry aneurysms on the external arteries that also cause cerebral haemorrhage.
2. Tiny dilatations on retinal capillaries seen with the ophthalmoscope in cases of DIABETIC RETINOPATHY.

It has become a valuable aid in the detection and monitoring of key retinal pathologies such as Choroidal Neovascularization, Diabetic Retinopathy, microaneurysms, and more.
New vessels and microaneurysms could not be seen on direct ophthalmoscopy but hard exudates and macular star could not be visualized on FA.
While there are still improvements needed to reliably capture and visualise microaneurysms, which are a hallmark of DR, OCT-A has already shown its potential in a study by Scarinci and colleagues, which reported that capillary dropout in the deep capillary plexus was associated with macular photoreceptor disruption in patients with DR.
Patients with pseudoaneurysms, arteriovenous fistula, multiple microaneurysms and aberrant vascularity related to angiomyolipoma or other renal tumors were excluded and six patients with nine TRAAs were included in the study.
The photos were checked for four types of retinopathy: arteriovenous nicking, focal arteriolar narrowing, retinal microaneurysms, and retinal hemorrhage.
Patients were classified as having diabetic maculopathy if there was leakage from microaneurysms, exudation or hemorrhages at macula.
A pediatric cardiologist performed transthoracic echocardiography and reported some bright spots on the right coronary artery with the suggestion of thrombi or microaneurysms. This case report is compiled after obtaining informed consent from the patient's parents.

In children, although it is common to demonstrate ophthalmoscopic findings such as isolated retinal microaneurysms or small unilateral hemorrhages (all of which are signs of nonproliferative diabetic retinopathy (NPDR)), it is extremely rare to find preproliferative retinopathy, proliferative retinopathy, or macular edema, regardless of the degree of metabolic control or the time of evolution of diabetes [4], with a clear tendency in our days to the decrease in the detection of retinopathy [4, 9, 10].
Eventually, this lead to weakness and saccular outpouching of the capillary walls (or termed microaneurysms).
The early stage of DR, with its featured complications of microaneurysms, hard exudates, and progressing hemorrhages, continues to lack effective treatments [2].
