He was accompanied by his wife Afroza Abbas and son Mirza Yasir Abbas, said Abba’s personal assistant Mizanur Rahman Sohel.
Sohel said Abbas departed Hazrat Shahjalal International Airport at 11:15am on a flight of Biman Bangladesh Airlines.
“Sir has gone to Bangkok for eye treatment. An appointment at Ruttonin Eye Hospital has been scheduled for today (Tuesday),” he said.
Sohel said the BNP leader is due to have eye surgery two days later.
He said Mirza Abbas’ family has requested all to pray for his speedy recovery.
Earlier, on August 13, BNP Secretary General Mirza Fakhrul Islam Alamgir also travelled to Bangkok for follow-up eye treatment at Ruttonin Eye Hospital. He is scheduled to return home this evening, reports UNB.
Fakhrul had previously undergone a successful surgery on his left eye for a retinal problem at the same hospital on May 14.
