The One Seoul Eye Clinic is located in Sinsa Square near Sinsa Station in Gangnam-gu, Seoul. Our ophthalmology specialists provide care for retinal disease, glaucoma, cataract and presbyopia, vision correction (LASIK, LASEK, implantable lenses), pediatric myopia, and dry eye. We are about 307m from Exit 6 of Sinsa Station on the Sinbundang Line.
Retinal vascular occlusion is sometimes called a stroke in the eye. There are retinal artery occlusion, retinal vein occlusion, and other retinal vascular diseases such as ocular ischemic syndrome and hypertensive retinopathy. Retinal vascular occlusion is a disease in which the retinal blood vessels are blocked due to circulatory problems, leading to retinal damage and hemorrhage due to decreased oxygen supply.
Retinal vascular occlusion can occur due to various causes, including advanced age and hypertension. The main causes are circulatory disorders (hypertension, arteriosclerosis, diabetes, hyperlipidemia, glaucoma) and decreased vascular function due to aging.
Depending on the location of the occlusion, it can be classified as central retinal artery occlusion or branch retinal artery occlusion. The cause is often unclear, but emboli or thrombi may act as triggers. In particular, central artery occlusion has a poor visual prognosis and may spread to systemic disease.
Central retinal artery occlusion causes the retinal artery to become very thin and the posterior pole retina to become cloudy.
Central retinal artery occlusion shows a black line where the occluded artery is not filled with fluorescein.
Depending on the location of the occlusion, it can be classified as central retinal vein occlusion or branch retinal vein occlusion. Vein occlusion can be caused by hypertension, diabetes, hyperlipidemia, etc. It is not considered an ophthalmic emergency and the prognosis is generally good, but due to the nature of the disease, the vein gradually narrows, and if not treated promptly, vision loss may occur. Therefore, systemic disease should be examined and treated accordingly.
Branch retinal vein occlusion causes the retinal vein to become tortuous and accompanied by hemorrhage.
Central retinal vein occlusion shows venous dilation and tortuosity.
Retinal vascular occlusion causes sudden vision loss without pain. The most common symptoms are vision loss and metamorphopsia (distorted vision), and overall vision loss is prominent, but depending on the location of the vascular occlusion, there may be no symptoms.
Retinal vascular occlusion can be diagnosed in various ways, and treatment is largely divided into drug therapy, intraocular injection, laser therapy, and surgery depending on the underlying disease.
Diagnosis methods: fluorescein angiography, indocyanine green angiography, optical coherence tomography, etc.
At The One Seoul Eye Clinic, various specialists are present to provide systematic and accurate examinations for safe treatment.
Retinal vascular occlusion is treated with drug therapy, laser therapy, intraocular injection, etc., depending on the cause.
If the central vessel, not a branch, is occluded, not only severe vision loss but also complications can occur, so prompt treatment is necessary.
