Congenital cataract

Signs and symptoms

A cataract is an opacity or cloudiness on or in the lens or capsule of the eye.  A congenital cataract is present at birth but an acquired cataract develops after birth.  Symptoms are visual - blurred vision, problems with glare, altered colour perception and double vision when using one eye (monocular diplopia).  Some of these symptoms may be associated with refractive error, or presbyopia - which is part of the normal ageing process. Examination with an ophthalmoscope is necessary to establish the presence of a cataract.

Establishing onset

The veteran may not have sought medical attention for a cataract until some time after the onset of symptoms, and this would normally be recorded in doctors' notes and/or hospital records.  However, these records may have been destroyed or can no longer be obtained.  Therefore, if there is a reliable history of appropriate symptoms and medical treatment at a particular time, this generally will be accepted, unless there is contradictory evidence.  Seek medical advice if it is unclear whether the claimed symptoms and treatment at that time can be attributed to cataract rather than to some other condition.
