This contrasts with a migraine, which causes an “excitable event”. The visual disturbance accompanied by a stroke usually has a “dimming event”, as though someone has taken a dimmer switch and turned it down. This results in a sudden loss in brain function. Migraine aura usually occurs within an hour before head pain begins and generally lasts less than 60 minutes. A stroke occurs when there is an interruption of blood flow to the brain or rupturing of blood vessels in the brain. Migraine aura symptoms include temporary visual or other disturbances that usually strike before other migraine symptoms such as intense head pain, nausea, and sensitivity to light and sound. The yellow line represents the retinaĪ stroke is an emergency and immediate treatment is required. If you think you have these symptoms, see your eye doctor the same day or go to the emergency room.įigure 1. There is no pain associated with a retinal detachment. Symptoms are accompanied by flashing lights in your side vision and include: The outcome of this condition will result in poor visual acuity. If the patient waits too long, fluid will build up behind the affected area and cause the retina to detach in the macula (location of the retina that processes the central vision). If a patient has a retinal hole or tear, they can prevent a retinal detachment from occurring by seeking medical help immediately. The retina is a tissue located at the back of the eye and its function gives us the ability to see. The key to recognizing an ocular migraine is that these photopic visual experiences are an “excitable event” in your vision.Ī retinal detachment is an emergency and can be repaired with good visual outcome if the patient acts in a timely manner. When this occurs, the photoreceptors will react even without “photopic phenomenon” (or signals of light). This causes the photoreceptors, which are light-receiving receptors at the back of the eye, to have a compromised blood supply. During an ocular migraine, the blood vessels involved will go through a constriction phase where the blood supply to the eye is diminished. These headaches tend to last 4 to 72 hours.Īn ocular or retinal migraine is known as a migraine without a headache. Migraines can be accompanied by an aura where you may see flashing lights. Possible symptoms accompanying the pain include nausea, vomiting, blurred vision, sensitivity to light and sound, and dizziness. A migraine consists of throbbing pain on the sides of the head and behind the eyes. Migraines are triggered by numerous factors such as hormonal changes, stress, diet, and changes in sleeping patterns. There are several types of migraines and it is important to recognize the differences. By definition, a migraine is a vascular disease, meaning it affects the body’s blood supply. It is imperative to distinguish between these conditions, as they require different forms of action.Ī migraine is a term that encompasses multiple, related conditions. Migraines, retinal detachments, and strokes can often be confused and mistaken for one another.
