Can choroidal defect read?
summary
Choroidal defect is one of the depressive deformities of vertebrate eyes. The pigment of retina and choroid is abnormal in the position of the ocular fissure because it keeps open. In some cases, a tear can be formed in the iris. This is called iris defect. Can choroidal defect be read.
Can choroidal defect read?
There are two types of choroidal defects: typical and atypical. The typical choroidal defects are mostly bilateral, occasionally monocular. The defect area was lack of choroid and retinal pigment epithelium. The range and shape of the defect area vary greatly. It is usually an upright obtuse triangle, shield or ellipse. The edge of defect area is clear and irregular pigmentation is often found. In the gray white defect area, the surface is smooth, and sometimes scattered brown spots can be seen, indicating that the brown sclera plate is still residual.
Atypical choroidal defect is rare. Most of them are monocular, often isolated in any area of fundus, sclera is exposed, slightly depressed, and pigmentation, which is the same as typical cases. Some people think that macular defect is atypical choroidal defect.
Typical choroidal defects occur in both eyes, under the optic disc, and also include the optic disc. The defect area showed no choroid, white sclera was seen through the thin retina, the edge was regular, there was pigmentation, often accompanied by microphthalmos, iris abnormalities, optic nerve abnormalities, lens defects and macular dysplasia. Atypical cases are more common, mostly monocular, can be located in any part of the fundus, macular area defect is the most common, central vision is superior, others are similar to typical cases.
matters needing attention
Choroidal defect may be accompanied by other congenital abnormalities such as microphthalmos, small cornea and partial iris defect. Most of them are related to the incomplete closure of embryonic cleft during the development of early embryonic eye. According to the clinical diagnosis. There is no special treatment, and surgery is feasible when complicated with retinal detachment.
