BNP Secretary General Mirza Fakhrul Islam Alamgir went to Bangkok, Thailand for emergency eye treatment early on Tuesday.
Fakhrul, along with his wife Rahat Ara Begum, left Hazrat Shahjalal International Airport for Bangkok at 2:45am on a Thai Airways flight, said BNP media cell member Sayrul Kabir Khan.
He said the BNP leader noticed a problem with his eyes on Monday morning and immediately visited United Hospital in Gulshan for treatment.
After examination, Sayrul said, doctors at the hospital advised that surgery on the retina of one of his eyes is urgently required.
"Following the doctors' advice, an appointment was promptly made at Rutnin Eye Hospital in Bangkok for the necessary treatment," he said.
On behalf of Fakhrul’s family members, Sayrul urged the country’s people to pray for the speedy recovery of the BNP Secretary General.
Earlier, on April 6, Fakhrul and his wife travelled to Singapore for medical check-ups and necessary treatment.
