Do not ignore the sudden signs of blurred vision.

After 5 days of sudden blurred vision, Ms. NN went to the doctor and was surprised to receive the result of central retinal vein occlusion. If detected and treated late, there is a high risk of blindness.

Unusual blurred vision shouldn't be taken lightly.

Despite having no pain, history of injury, or other unusual symptoms, for about 5 days now, Mrs. NN (50 years old, Hanoi ) has experienced a sudden decrease in vision in her right eye. Mrs. N quickly sought medical attention at the hospital.

The results showed that Ms. N's right eye had a visual acuity of 3/10, and her vision did not improve with glasses. Notably, fundoscopy revealed signs of optic disc edema, retinal vein dilation, and hemorrhage throughout the retina. A retinal tomography scan showed cystic macular edema.

Ms. N was diagnosed with central retinal vein occlusion and advised to undergo treatment with Anti-VEGF injections.

According to studies, 70% of cases of central retinal vein occlusion occur in people with cardiovascular disease such as hypertension, atherosclerosis, and other cardiovascular diseases. Risk factors for the disease include hypertension, high blood lipid levels, diabetes, smoking, and glaucoma.

Dr. Khuat Trang Anh, an ophthalmologist at Medlatec Healthcare System, explains that central retinal vein occlusion is a blockage of venous blood flow due to thrombosis. If the vein is blocked, draining blood from the macular region, the patient will experience macular edema and severe vision loss.

The disease typically causes a decrease in vision, ranging from mild to severe, and often occurs suddenly. The patient's field of vision may also narrow, or they may see black spots. Aside from these symptoms, the patient does not experience eye pain, redness, or tearing.

Among retinal vascular diseases, central retinal vein occlusion is the second leading cause of blindness worldwide after diabetic retinopathy. In recent years, along with the increase in diseases such as hypertension, cardiovascular disease, diabetes, dyslipidemia, etc., central retinal vein occlusion has also shown an upward trend.

3 things to keep in mind for disease prevention.

Dr. Trang Anh emphasized that if central retinal vein occlusion is not treated early, it can cause many dangerous complications such as glaucoma, intraocular hemorrhage, retinal detachment, or even blindness... Therefore, it is necessary to detect and treat the disease early as soon as symptoms appear to minimize the risk of unpredictable complications.

To effectively prevent central retinal vein occlusion in particular and protect eyesight in general, Dr. Trang Anh recommends that people pay attention to three things: specifically, people need to treat high-risk systemic diseases such as atherosclerosis, dyslipidemia, hypertension, diabetes, kidney disease, etc.;

Secondly, regular eye exams are recommended for older adults, those with nearsightedness, or those with vascular diseases, ideally once a year. It's crucial to seek immediate medical attention if any unusual symptoms are noticed so that a doctor can provide appropriate treatment and offer a chance to protect and restore vision.

Thirdly, adopt a scientific and healthy diet to reduce atherosclerotic plaques and lessen blood vessel blockage. Specifically, eat low-fat foods, maintain regular physical activity, and quit smoking.
