HELLO MR DAVID,

I AM an amateur keeper of insectivorous birds, especially the White-rumped Shama AND MY INQUIRY CONCERNS THIS BIRD. THE BIRD IS APPROXIMATELY ONE YEAR OF AGE AND PRESENTING THE PROBLEM THAT IN ONE OF ITS EYES IS CATARACT that covers all of it.

At first it was almost not noticeable but now it looks white because of this problem. IF YOU CAN ADVISE ME ON THIS HUGE PROBLEM BECAUSE I would appreciate ME DA MUCHA PENA who became blind.

IS THERE ANY REMEDY OR TREATMENT OR Who can I contact. THANK YOU FOR YOUR ATTENTION AND INTEREST. I congratulate you on your birds that ARE AN INSPIRATION FOR NATURE LOVERS WITH NOT SO MANY YEARS OF EXPERIENCE OF SUCH BIRDS IN THEIR CARE.

SEE YOU SOON AND THANK YOU AGAIN.

Hi Juan,

I am afraid there that the only reliable cure for cataract is to have an operation to remove the spoilt lens and replace it with an artificial lens. This is routinely done with humans and there have also been successful trials on dogs. As far as I know, it has never been done with birds.

What happens with cataract is that the lens in the eye oxidises and gradually becomes opaque until vision is completely blocked. The effect is somewhat like placing an egg in hot water. The egg-white will turn from clear to white. The process cannot be reversed although there are claims on the internet that this is possible with eye-drops.

Best regards,

David
