We probably didn't need a formal study to tell us this, but cosmetic iris implants are bad news.

A small study found that more than 90% of patients who had a cosmetic iris implant to change their eye color had a complication.

How did they figure that out?

A French research team sent questionnaires to ophthalmologists asking safety and complication questions for each implanted eye. A total of 33 questionnaires representing 65 eyes were included in the study.

What was the most common complication?

The most common was corneal decompensation, and a diagnosis of glaucoma was made in more than half of the cases. (via)

Can a machine diagnose glaucoma better than you?

Maybe not better, but it's close.
A study published in Eye addressed the question of whether an artificial intelligence (AI) software can detect glaucoma as well as an ophthalmologist or optometrist.

Tell me about the study.

The research team used 94 stereoscopic optic disc photos (40 healthy controls, 48 with glaucoma, and six with ocular hypertension). These images were taken from previous studies in which ophthalmologists and optometrists analyzed the images to determine whether a patient had glaucoma. They scanned these images into the AI system and compared the results.

What did they find?

The AI system was able to detect glaucomatous optic nerves with 83% accuracy, which was similar to the accuracy of the ophthalmologists and optometrists.

While we're on the topic of AI ...

Other things are happening, too. The VA Healthcare System is testing Technology-based Eye Care Services (TECS), and there is new AI that can diagnose angle closure.
