Retinal detachment

Introduction Retinal detachment is the separation of the neuroepithelial layer of the retina from the pigment epithelial layer. 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.

Cause

The disease is more common in middle-aged or elderly people, most of them have myopia, and both eyes can be followed. The causes of the disease include lattice-like and cystic degeneration in the peripheral part of the retina, vitreous liquefaction and retinal adhesion. These factors are related to age, heredity, trauma and other factors. The traction of the vitreous to the retina is more important in the pathogenesis. In recent years, the number of young patients has also increased, and even students who are under the age of ten have appeared. Most of the causes of the disease are trauma or excessive use of the eye.

Ultrasound examination of the eyeball and eyelid and CT examination of the temporal region

Ophthalmologists can use the ophthalmoscope to observe holes, tears, or detachments in your retina. Ultrasound may be helpful if the blood in the vitreous cavity blocks the doctor's field of vision. Ultrasound examination of the eyeball is a painless examination that uses ultrasound to penetrate your eye and then bounce in the retina. The rebounding sound waves produce images of the retina and other eye structures on the display. This test provides the doctor with useful information to determine if your retina is detached.

Differential diagnosis

1, retinoschisis, degenerative retinoschisis is located in the lower peripheral fundus, a hemispherical lobe, developed by cystic degeneration. The inner wall is thin and transparent. Pigmentation can occur near the outer wall edge. If the inner and outer walls are ruptured, it becomes a true hole and a retinal detachment occurs. Congenital retinoschisis is found in school-age children. With a family history, retinal blood vessels are often accompanied by white sheaths. The lesion is located below the fundus or below the sac, with bilateral symmetry. If the inner wall breaks into a large hole, it is similar to the sawtooth edge. But its leading edge is not sawing.

2, central serous chorioretinopathy (referred to as "middle pulp") "middle pulp" itself is also the macular layer or its vicinity of the neuroepithelial shallow detachment. It is a self-limiting disease that can resolve on its own. Different from primary retinal detachment. Retinal detachment invades the common plaque and causes visual distortion and small vision, which is the same as the "middle pulp" symptom. The surrounding area should be inspected.

3, ural effusion (choroidal effusion). Often accompanied by retinal detachment, hemispherical bulge, easy to move with changes in body position, no holes.

4, the physical retinal detachment of the vitreous opacity, more easily misdiagnosed. It can be identified by ultrasound or CT scan.

5. The vesicular retinal detachment is smooth and has no wave-like wrinkles. The effusion under the neuroepithelial layer is clear and can flow rapidly with the change of body position without cracks, which is different from this disease.
