Ice is a Welsh X mare with a nasty intraocular inflammation (uveitis) causing corneal changes in her left eye. This particular condition has been reclassified as ‘Heterochromic Iridocyclitis with Keratitis (HIK)’ and is a difficult disease to control. Recently she came to the hospital to have sustained release cyclosporine implants placed in her left eye.
These are placed under the white of the eye against the choroid, which provides the major blood supply to the inside of the eye. These implants are only available to ophthalmologists so referral is required for this surgery, which is performed under general anaesthesia.
Ice is doing well so far, and the implants will last for 3.2 years. Here's a photo of her and her owner out and about a few weeks after the operation.
