Tijdelijke stoornissen van het zien met één oog

Transient monocular vision loss (TMVL) caused by temporary disturbance of blood flow to the retina is a harbinger of future vascular complications. The diagnosis may be difficult, not only because it is solely dependent on history taking, but also because the range of monocular visual symptoms a patient may experience is wide. The classic pattern of a sudden black or grey visual field, or a curtain that is drooping in front of one eye, easily fits in the diagnosis of TMVL; however, coloured vision or flashes should not always be considered as benign. The distinction between visual symptoms of one or both eyes should receive attention during history taking. It is the professional expertise of the neurologist and ophthalmologist which should make it possible to establish the correct diagnosis. A patient suspected of a retinal TIA should be evaluated and treated with the same urgency as someone with a cerebral TIA.
