What began as concern expressed by Pakistani cricket greats has now snowballed into an unprecedented, cross-border appeal from Indian and international former captains, cutting across political and national divides.

Pakistan’s imprisoned former Prime Minister Imran Khan will undergo treatment for an eye condition at a specialized medical facility, a Cabinet minister said after the Supreme Court ordered a medical evaluation amid concerns about his eyesight.

A fierce political row has erupted in Pakistan over the health of former Prime Minister Imran Khan, with Interior Minister Mohsin Naqvi accusing his sister, Aleema Khanum, of politicising his medical condition and delaying his treatment.

A team of doctors treating Pakistan's imprisoned former premier Imran Khan has reported "improvement" in his eyesight, his personal physician said, but added he could neither confirm nor deny the assessment as he had no access to the former premier.

The lawyer for the former prime minister claimed he had lost 85 percent of the vision in his right eye because of delayed treatment in prison.

The PTI stated that Imran Khan’s family was not taken into confidence and demanded that any medical examination or treatment be conducted in the presence of his personal doctors and at least one family member.
