According to Hong Kong media HK01, a 35-year-old man living in Hangzhou, Zhejiang Province, China, felt severe blurred vision in his right eye after playing smartphone games from 2-3 a.m. I thought it was just eye fatigue, so I ended the game and went to bed, but I didn't go to the hospital until I got a serious visual impairment again the next evening.
Doctors diagnosed it as 'CRAO(CRAO)' after the examination.
Also called 'eye stroke', this disease is an emergency disease that causes sudden, painless vision loss as the central retinal artery that supplies blood to the retina is blocked. Despite intensive treatment, A only partially recovered his vision.
The hospital said the patient had risk factors for vascular diseases such as obesity, high blood pressure, hyperglycemia, and hyperlipidemia.
The medical team explained that the golden time for treating retinal central arterial obstruction is within 90 minutes of the onset, and that permanent damage caused by retinal ischemia was inevitable due to delays of more than 24 hours.
Experts said retinal central artery occlusion is characterized by sudden, painless vision loss, and symptoms appear as if a black curtain has come down in front of your eyes. On the contrary, 'retinal venous obstruction (CRVO)' is more common, with symptoms such as blurred vision, distorted vision, and color slowing.
Both diseases are painless and easily mistaken for simple eye fatigue, but retinal damage remains permanent if treatment is delayed. In particular, in winter, blood clots are likely to occur due to vasoconstriction and blood pressure fluctuations, increasing the incidence rate. Dehydration can also increase the risk by making blood sticky.
Experts emphasized that 'eye stroke' is not limited to the elderly, but is also increasing in young people, and that so-called '3 high' patients, arteriosclerotic patients, and long-term smokers, such as hypertension, hyperglycemia, and hyperlipidemia, should strive for prevention through regular medical checkups.
