Amaurosis fugax - what does this mean
What happens during the disease - amaurosis fugax
Развитие преходящей слепоты после анестезии при операциях на носовой полости обусловлено анатомической близостью орбиты и носа. Для глазницы, наружного носа и внутриносовых структур характерна общность кровоснабжения и иннервации. Ученые полагают, что возникновение симптомов связано со спазмом сосудов под воздействием высоких концентраций адреналина. Однако не исключено, что спастическое сокращение может быть рефлекторным. При использовании местных анестетиков низкого качества возможно токсико-аллергическое поражение волокон зрительного нерва. Своевременное оказание неотложной помощи при спастическом генезе патологии способствует быстрому регрессу офтальмологической симптоматики.
При проводниковой анестезии в области иннервации переднего и заднего решетчатых нервов повредить зрительный нерв можно кончиком иглы. Нарастание гематомы потенцирует компрессию нервных волокон. Важная роль отводится острому нарушению артериального кровообращения, что связано с тромбозом, эмболией или спазмом центральной артерии. В патогенезе патологии также присутствует ишемия в зоне кровоснабжения глазничной, задней цилиарной артерии или артерии сетчатки. Зрительная дисфункция при височном артериите вызвана трофическими нарушениями в области бассейна сосудов, питающих зрительный нерв.
Clinical Pattern
How does a doctor diagnose
- Comprehensive medical history and physical examination
- Optical coherence tomography (OCT) scan
- Fluorescein angiography
- Carotid Doppler ultrasound
- Magnetic resonance imaging (MRI) scan
- Electrocardiogram (ECG)
- Echocardiogram (ECHO)
- Blood tests
- Visual field testing
Treatment and Medical Assistance
- Prescribe medications to reduce the risk of stroke or other vascular events
- Prescribe medications to reduce inflammation and improve circulation
- Prescribe medications to lower cholesterol levels
- Provide lifestyle advice, such as quitting smoking, exercising regularly, and eating a healthy diet
- Refer the patient to a low-vision specialist for assistive devices and other treatments
- Refer the patient to a neurologist for further evaluation and treatment
- Perform regular eye exams to monitor the patient's vision
Amaurosis fugax - Prevention
Main symptoms of the disease amaurosis fugax
Decreased vision
(Impaired vision, Blurred vision, Diminished vision, Reduced vision, Fuzzy vision, Clouded vision, Hazy vision, Poor vision, Weak vision, Low vision)
Decreased vision is a symptom of many underlying conditions. It can range from mild blurring of vision to complete loss of sight. It can develop gradually or suddenly, and may be accompanied by pain, headaches, or double vision. Depending on the underlying cause, it can be partial or complete, affec...
Decreased pupillary light reflex
(Diminished pupillary reflex, Impaired pupillary reflex, Abnormal pupillary reflex, Reduced pupillary reflex, Weak pupillary reflex, Slowed pupillary reflex, Blunted pupillary reflex, Lowered pupillary reflex, Lessened pupillary reflex, Subdued pupill...)
Decreased pupillary light reflex is a medical symptom characterized by reduced pupil constriction when exposed to light. It typically starts with a decrease in the size of the pupil when exposed to light, followed by a slower-than-normal return to its original size. It may also be accompanied by a d...
Blindness
(Vision loss, Lack of sight, Unable to see, Eye defect, Visual impairment, Partial sight, Darkness, Obscurity, Blind spot, Night blindness)
Blindness is the inability to see. It can be caused by physical damage to the eyes, or by damage to the optic nerve or brain. It can be partial or complete, and can develop suddenly or gradually. Manifestations of blindness can include difficulty recognizing faces, difficulty reading, difficulty fin...
