Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Left untreated, this event carries a high risk of stroke; after carotid endarterectomy, which has a low operative risk, there is a very low postoperative stroke rate." [ 43 ] However, the rate of subsequent stroke after amaurosis is significantly less than after a hemispheric TIA, therefore there remains debate as to the precise indications for ...
Acute dacryoadenitis is most commonly due to viral or bacterial infection. Common causes include mumps, Epstein-Barr virus, staphylococcus, and gonococcus. Chronic dacryoadenitis is usually due to noninfectious inflammatory disorders. Examples include sarcoidosis, thyroid eye disease, and orbital pseudotumor.
Dental abscess; Other names: Dentoalveolar abscess, Periapical abscess, tooth abscess, root abscess: A decayed, broken down tooth, which has undergone pulpal necrosis.A periapical abscess (i.e. around the apex of the tooth root) has then formed and pus is draining into the mouth via an intraoral sinus ().
A transient ischemic attack (TIA), commonly known as a mini-stroke, is a temporary (transient) stroke with noticeable symptoms that end within 24 hours. A TIA causes the same symptoms associated with a stroke, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language or slurred speech.
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
(H49-H50) Strabismus (Crossed eye/Wandering eye/Walleye) — the eyes do not point in the same direction (H49.3-4) Ophthalmoparesis — the partial or total paralysis of the eye muscles (H49.4) Progressive external ophthaloplegia — weakness of the external eye muscles (H50.0, H50.3) Esotropia — the tendency for eyes to become cross-eyed
Furthermore, some patients regain vision completely, as is the case with transient cortical blindness associated with eclampsia and the side effects of certain anti-epilepsy drugs. Recent research by Krystel R. Huxlin and others on the relearning of complex visual motion following V1 damage has offered potentially promising treatments for ...
