SINGAPORE: The new anti-VEGF treatment option for diabetic retinopathy patients
has been hailed by experts as being more effective than traditional laser
treatments.
Diabetic retinopathy, a condition
of the eyes affecting diabetics that causes swelling and blurred vision, plague
an approximate 100,000 Singaporeans say experts.
"Anti-VEGF therapy is a new
therapy which effectively reduces the swelling in the eye," said Professor
Wong Tien Yin, Executive Director at the Singapore Eye Research Institute.
"It works by suppressing growth factors that causes the blood vessels to
leak and the retina to swell."
Diabetic retinopathy patients
traditionally undergo laser treatment to treat their symptoms.
However Professor Wong noted that
visual improvement after laser treatments was not common and that many
continued to lose vision after treatment, adding that the laser option was
"good but not completely satisfactory".
"The new anti-VEGF therapy
essentially helps improve vision in patients... and therefore patients have a
better quality of life," he said.
However, anti-VEGF treatments can
cost up to S$42,000, compared to laser treatments which cost between S$500 and
S$1,600.
Patients undergoing anti-VEGF
undergo seven intro-ocular injections into the eye in the first year of
treatment, followed by four injections in the second year and three in the
third year. The each injection costs between S$1,200 and S$3,000.
Despite that, more than a
thousand patients in Singapore have undergone anti-VEGF treatment since
hospitals started offering it last September.
Professor Wong also noted that
screening for diabetic retinopathy could be further streamlined to ensure
better detection.
"In many countries,
including Singapore, family general practitioners conduct screening for
diabetic retinopathy," he said. "Despite their medical background and
training, their evaluation may be limited due to busy clinic schedules".
Instead, non-physicians or eye
research technicians should also be used to detect diabetic retinopathy said
Professor Wong, citing a local study conducted in 2009 that showed trained eye
research technicians outperforming family general practitioners in detecting
diabetic retinopathy.
