Blocked blood vessels in the eyes are generally categorized into arterial and venous blockages. Patients with arterial blockages can regain some vision if they are treated in a timely manner, but if the optimal time for treatment is exceeded, vision is generally more difficult to regain. Patients with venous blood vessel blockage can regain some vision if they are actively treated.
Because the arteries are the blood vessels that supply the retina with nutrients, once there is a blockage of the arteries, it can cause ischemic and hypoxic changes in the retina, and the patient can experience a significant loss of vision. The patient needs to lower the intraocular pressure and dilate the blood vessels in time, which can lead to some recovery of vision. However, if the optimal treatment time is exceeded, the retinal cells will die due to ischemia and it will be difficult to restore the patient’s vision.
Vein blockage patients because of venous blood flow obstruction, so that the retina ischemia, hypoxia, the patient’s vision can be reduced, the patient can follow the doctor’s instructions to use nitroglycerin and other vasodilator drugs, to promote the recovery of vision.
It is recommended that patients with ocular venous occlusion consult a doctor in a timely manner to assess their condition and under the guidance of a professional physician to avoid delaying their condition.
