Introduction

Introduction 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 is drastic or even completely blind, it belongs to the category of "blindness" of Chinese medicine. Suddenly, the patient's flying mosquitoes are aggravated, and a flash of light appears in one direction. Vision distortion, followed by large black shadows in front of the eyes, the visual acuity is seriously degraded, if the black shadow expands all detached, the vision is completely lost or only the light sense.

Cause

Cause

(1) Internal injuries and fatigue. Old age or diet, hunger and suffocation, or excessive fatigue, spleen reported injury, health and dereliction of duty, resulting in water liquid suspension, can not move, resulting in retinal blue or gray-yellow spherical bulge, visible red crack around the macula hole.

(2) The liver gas is not comfortable, the air machine is not smooth, which affects the operation of the tri-coke water and the gasification disorder. The water is wet on the eyes, causing the rectification of the retinal water to be blocked, forming a pathological change of the blue-blue spherical bulge.

(1) Suddenly, the flying mosquitoes are aggravated, and a flashing sensation appears in one direction, indicating that the retina is detached in this direction.

(2) There is a fluorescent flicker in front of the eyes, and the object is deformed. Then there is a large black shadow in front of the eyes. When it is separated from the macula, the visual acuity is seriously degraded. If the black shadow is enlarged, all of the vision is lost or only the light is lost. sense.

(3) The white field of view is missing from the corresponding part of the detachment, but the change of the color field of view may occur earlier, and the blue field of view defect is larger than the range of the white field of view defect.

(4) Reduced intraocular pressure.

(5) Fundus examination: 1 The retinal detachment is a gray-gray corrugated bulge, and the dark red blood vessels undulate with the ripples. When the eyeball is rotated, the detachment of the omentum can be seen to have a slight fluctuation of the retina. Can completely cover the optic nipple. 2 You can find round or horseshoe-shaped to many red holes. Its position is the most in the upper quadrant, the second is the lower quadrant, the upper quadrant is again, and the lower nasal quadrant is the least. There are more than 3 degrees of vitreous opacity.

(6) Scleral transillumination examination, the pupil area may have red light reflection.

Diagnosis

Differential diagnosis

Should be differentiated from retinal cleft palate

Retinal palpebral fissure: refers to the division between the inner layer of the retina and the rest of the retinal tissue layer based on congenital dysplasia or acquired inflammation. In the lower part of the retina, a translucent spherical bulge is seen, without posterior vitreous detachment and retinal tear.
