Although astigmatism may be asymptomatic, higher degrees of astigmatism may cause symptoms such as blurred vision, double vision, squinting, eye strain, fatigue, or headaches. [7] Some research has pointed to the link between astigmatism and higher prevalence of migraine headaches.
Atypical trigeminal neuralgia ( ATN ), or type 2 trigeminal neuralgia, is a form of trigeminal neuralgia, a disorder of the fifth cranial nerve. This form of nerve pain is difficult to diagnose, as it is rare and the symptoms overlap with several other disorders. [ 1] The symptoms can occur in addition to having migraine headache, or can be ...
Visual snow syndrome (VSS) is an uncommon neurological condition in which the primary symptom is that affected individuals see persistent flickering white, black, transparent, or colored dots across the whole visual field. [7] [4] Other common symptoms are palinopsia, enhanced entoptic phenomena, photophobia, and tension headaches.
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically (without headache), also known as visual migraine or migraine aura. [ 4]
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Occipital neuralgia. Occipital neuralgia (ON) is a painful condition affecting the posterior head in the distributions of the greater occipital nerve (GON), lesser occipital nerve (LON), third occipital nerve (TON), or a combination of the three. It is paroxysmal, lasting from seconds to minutes, and often consists of lancinating pain that ...
Mechanically induced Roemheld syndrome is characterized by pressure in the epigastric and left hypochondriac region. Often the pressure is in the fundus of the stomach, the esophagus or distention of the bowel. It is believed this leads to elevation of the diaphragm, and secondary displacement of the heart. This reduces the ability of the heart ...
Cervicogenic headache is a type of headache characterized by chronic hemicranial pain referred to the head from either the cervical spine or soft tissues within the neck. [1] [2] The main symptoms of cervicogenic headaches include pain originating in the neck that can travel to the head or face, headaches that get worse with neck movement, and limited ability to move the neck.
