retinal Roth spots
Introduction
Introduction Retinopathy can cause retinal choroid rupture and hemorrhage caused by ocular blunt contusion. The anterior vitreous hemorrhage can be caused by damage of the ciliary body. It is fan-shaped or round, and may have a white center. Sometimes the fundus is only round. The white point is called the Roth point.
Cause
Cause
In addition to bacterial embolism, leukemia cell infiltration caused by central white spot bleeding, hemorrhage after retinal hemorrhage can form a central white spot due to platelet-fibrin agglutination.
Commonly caused by blockage of immune complexes in infective endocarditis. Roth's spots are seen in leukemia, diabetes, subacute bacterial endocarditis, and pernicious anemia.

Eye and sacral area CT examination ophthalmoscopy
Fundus examination, which is typically viewed by fundoscopy (using an ophthalmoscope to view inside the eye) or a slit lamp. Ultrasound examination has a great diagnostic value for vitreous hemorrhage, especially when it is not directly visible. A small amount of diffuse bleeding may result in a negative result with B-mode ultrasound. This is because there is not enough echo interface in the vitreous, and type A Ultrasound scans may show low baseline echoes. When vitreous hemorrhage is dense, both low- and medium-amplitude scattered echoes can be seen in either type A or B-mode ultrasound, and when scanned with high sensitivity, bleeding Density and distribution are shown to be clearer; scans that reduce sensitivity can cause echo amplitude to drop, and most echo points are removed, thus determining whether retinal detachment is present at the same time.
Diagnosis
Differential diagnosis
1. White visual field defect: The retina is separated from its own pigment epithelial layer. The blue-red corrugated spherical bulge at the bottom of the eye, the dark red blood vessels with the corrugated undulations and round red holes, the white visual field defect is the main feature. More common in high myopia and elderly patients, more men than women, is a serious eye disease. Early and timely treatment can control its development. Once the omentum is detached, the visual acuity drops sharply, which belongs to the category of blindness of Chinese medicine.
2. Retinal detachment: Retinal detachment is the separation of the neuroepithelial layer and pigment epithelial layer of the retina. There is a potential gap between the two layers, and the liquid retained in the gap after separation is called subretinal fluid. According to the cause, it can be divided into rhegmatogenous, traction and exudative retinal detachment. The part of the retinal detachment does not work properly, and the brain accepts incomplete or total loss of images from the eye.
