An 80-year-old imprisoned Turkish man, named Abdullah Aydoğan, went blind in one eye in prison, according to a report by Journalist Sevinç Özarslan.

The elderly man has been in prison since January 7, 2019 over alleged links to the Gulen group which the Turkish government accuses of masterminding a coup attempt in 2016. The group denies any involvement.

He reportedly suffers from a series of advanced diseases, including hearing loss, hypertension, diabetes and hernia.

Turkey experienced a military coup attempt on July 15 that killed over 240 people and wounded more than a thousand others. Immediately after the putsch, the Justice and Development Party (AK Party) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen group.

The group denies any involvement. The Turkish gov’t initiated a widespread purge aimed at cleansing sympathizers of the group from within state institutions, dehumanizing its popular figures and putting them in custody.

More than 500,000 people have passed through police custody and 60,000 of them were remanded in prison
