[10] [11] The condition is typically always present and has no known cure, as viable treatments are still under research. [12] Astigmatism, although not presumed connected to these visual disturbances, is a common comorbidity. Migraines and tinnitus are common comorbidities that are both associated with a more severe presentation of the ...
Major symptoms are sudden loss of vision (partial or complete), sudden blurred or "foggy" vision, and; pain on movement of the affected eye. [4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.
Illusory palinopsia is often worse with high stimulus intensity and contrast ratio in a dark adapted state.Multiple types of illusory palinopsia often co-exist in a patient and occur with other diffuse, persistent illusory symptoms such as halos around objects, dysmetropsia (micropsia, macropsia, pelopsia, or teleopsia), Alice in Wonderland Syndrome, visual snow, and oscillopsia.
Chronic progressive vision loss that mimics a compressive lesion. The main features that differentiate AON from the more common typical demyelinating optic neuritis is the poor recovery of vision and the chronic or recurrent or bilateral course of AON. [2] Furthermore, the workup for multiple sclerosis including MRI, will be negative. Thus, it ...
Palinopsia (Greek: palin for "again" and opsia for "seeing") is the persistent recurrence of a visual image after the stimulus has been removed. [1] Palinopsia is not a diagnosis; it is a diverse group of pathological visual symptoms with a wide variety of causes.
A surgical technique offered is to create a "reading eye" and a "distance vision eye", a technique commonly used in contact lens practice, known as monovision. Monovision can be created with contact lenses, so candidates for this procedure can determine if they are prepared to have their corneas reshaped by surgery to cause this effect permanently.
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
Fluorescein angiographic studies [9] [10] have demonstrated that during the acute phase of NAION, there is a delay in blood flow to the optic disc, suggesting a potential impairment in the arteries directly supplying it. Other research indicates that a drop in blood pressure within specific critical areas of the optic disc's blood supply ...
