When we talk about eye cancer, we can be talking about the eyeball and intraocular structures, but also extraocular structures. The symptoms are then different. When cancers affect the structures around the eye, in the orbit, there is a forward displacement of the eye caused by the tumour, resulting in exophthalmos and sometimes even a limitation of eye movements causing double vision. When the cancer affects the surface of the eyeball or the eyelids, it is most often visible to the naked eye and can be assessed by your ophthalmologist during a consultation to determine the cause. When the cancer affects the inside of the eye, the patient experiences indirect symptoms of these tumours. Most often, this involves a reduction in visual acuity. That's why we advise you to contact your ophthalmologist as soon as possible if you experience any unusual or new ophthalmological symptoms.
