[Ocular manisfestations of systemic disease].

In many cases, patients with systemic diseases may present with a variety of ocular manifestations. The most common of these are "red eye" or a visual disturbance."Red eye" may be the first symptom of a condition from the group of rheumatic diseases and urgently mandates an ophthalmological investigation. Visual disorders occur, for example, in an underlying diabetic condition or arterial hypertension. Patients with arterial hypertension and/or diabetics must consult an ophthalmologist at regular intervals. Not only the underlying disease itself, but also its treatment can give rise to ocular complications. Patients on certain drugs - such as chloroquine or ethambutol should be referred for an ophthalmological examination at regular intervals.
