Screening Scheme Description

ECVO Eye Examination

ECVO Eye scheme

In addition to the BVA/KC/ISDS Eye Scheme the Kennel Club now also record the ECVO (European College of Veterinary Opthalmologists) Eye Scheme.

The ECVO Eye Scheme was established in 1998 and covers 14 inherited eye conditions in dogs. Dogs are classified as unaffected, affected or suspicious. However, it also includes a general examination of the eye and adnexa, so it may reveal other (not inherited) eye diseases as well.

In general, the best age for eye testing is before a dog has reached one year old and thereafter on an annual basis. However, in some breeds, it is necessary to test them as young puppies (usually between six and twelve weeks of age) and so details of litter screening are also included in the literature although results of litter screening are not published.

How do I get my dog's eyes tested under the Scheme?

The Scheme is according to the ECVO protocol, by an ECVO diplomate, click here to find the ECVO diplomates in the UK. Partial or preliminary examinations are not permitted. Gonioscopy may be completed as an additional examination. A certificate is issued upon completion of the examination.

Details of all lesions and conditions found at the time of examination, whether relating to hereditary eye disease or not, are recorded in the descriptive comments section in the middle of the Certificate using drawings and/or written remarks.

It is recommended that “suspicious” cases, after the prescribed period, are re-examined by the National Panel or Chief Panellist, whose decision will be final.

Alternatively, re-examination of cases previously found "suspicious" can be done by the first examiner or another Panellist.
