More than 50,000 people in Taiwan have been diagnosed with glaucoma, an eye disease that can lead to blindness if not treated properly.
But despite the seriousness of this disease, an estimated 250,000 people are not aware that they are affected by glaucoma and consequently have not received any treatment, doctors said in Taipei yesterday.
“Glaucoma is the second leading cause of blindness worldwide,” said Lu Da-wen (呂大文), chief of glaucoma services at Tri-Service General Hospital’s Department of Ophthalmology.
Lu said the average age of glaucoma patients is falling, and that younger patients suffer from a faster rate of disease progression.
“[Younger patients] have poorer compliance with medical procedures and often miss the golden period of treatment,” Lu said, adding that “the two greatest challenges in glaucoma treatment is patient compliance and effective control of eye pressure.”
“I discovered I had glaucoma when I was in the fifth grade,” said 24-year-old Jia Fan (范振嘉).
He went to the doctor because he “saw a ring of colorful lights” around bright objects. Like many young glaucoma patients, Fan delayed treatment until he experienced extreme pain.
“When I went to the doctor [for the second time], the pressure in my right eye had reached 60mmHg,” he said.
Pressure in a normal eye should be between 8mmHg and 21 mmHg.
Fan received medication to lower his eye pressure, but he discontinued treatment soon after the pain went away because his college entrance exams were approaching. When he was in his second year in college, the pain returned and he had to undergo surgery.
“Now I use eyedrops every day and my eye pressure has returned to normal,” said Fan, who has only 10 percent of his field of vision left.
While other treatment methods such as laser surgery are also available, “laser surgery not only carries higher risk, but also produces negative side effects such as reducing contrast perception,” said Lany Kuo (柯美蘭), director of Hsinchu General Hospital’s Department of Ophthalmology.
“Once-daily medication regimens help reduce involuntary non-compliance,” Kuo said.
From Sept. 1, DuoTrav, a medication used to treat certain forms of glaucoma, will be covered by the National Health Insurance, the doctors said.

From April 7 to Saturday last week, 139,848 people sought medical help for diarrhea-related illness, a 15.7 percent increase from last week’s 120,868 reports, CDC Epidemic Intelligence Center Deputy Director Lee Chia-lin (李佳琳) said.

A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
