Oxybutynin, sold under the brand name Ditropan among others, is an anticholinergic medication primarily used to treat overactive bladder.It is widely considered a first-line therapy for overactive bladder due to its well-studied side effect profile, broad applicability, and continued efficacy over long periods of time.
In many cases, only one eye is affected and the person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye. People may also engage in "eccentric viewing" using peripheral vision to compensate for central vision loss characteristic in genetic, toxic, or nutritional optic neuropathy.
A page or photograph which shows the same image twice, but slightly displaced–from a printing mishap, a camera moving during the shot, etc.–can cause eye strain due to the brain misinterpreting the image fault as diplopia and reacting by adjusting the sideways movements of the two eyeballs, in an attempt to fuse the two images into one. Eye ...
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.
Many variations occur, but scintillating scotoma usually begins as a spot of flickering light near or in the center of the visual field, which prevents vision within the scotoma area. It typically affects both eyes, as it is not a problem specific to one eye. [5] [6] The affected area flickers but is not dark. It then gradually expands outward ...
The blurred vision usually resolves within 10 weeks but individuals are often left with less vivid color vision, especially red, in the affected eye. [ citation needed ] A systemic intravenous treatment with corticosteroids may quicken the healing of the optic nerve, prevent complete loss of vision and delay the onset of other symptoms.
Some glaucomas (e.g. open angle glaucoma) cause gradual loss of vision and some others (e.g. angle closure glaucoma) cause sudden loss of vision. [6] It is one of the leading cause of blindness worldwide. [2] Diabetes: Poorly controlled blood sugar can lead to temporary swelling of the lens of the eye, resulting in blurred vision. While it ...
One method of balancing the neurotransmitters is through blocking central cholinergic activity using muscarinic receptor antagonists. Atropine acts on the M2 receptors of the heart and antagonizes the activity of acetylcholine. It causes tachycardia by blocking vagal effects on the sinoatrial node. Acetylcholine hyperpolarizes the sinoatrial ...
