The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
This impairs its function, potentially leading to vision loss. [2] [4] Retinal detachment often requires urgent medical intervention to prevent permanent vision loss. [3] Retinal detachments are divided into three main types based on their distinct causes. [6] Rhegmatogenous retinal detachment is caused by a tear or break in the retina.
This conjunctivoplasty surgery to correct conjunctivochalasis typically involves resection of an ellipse-shaped segment of conjunctiva just inferior to the lower lid margin, and is usually followed either by suturing or amniotic membrane graft transplantation to close the wound.
Alcohol intoxication can cause blurred vision. Use of cycloplegic drugs like atropine [4] or other anticholinergics cause visual blur due to paralysis of accommodation. [3] Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2 ...
Addressing underlying cause (e.g., steroids for inflammation, [1] surgery for trauma), vision rehabilitation: Medication: Corticosteroids (for optic neuritis), other medications depending on the cause: Prognosis: Variable; some cases recover, others lead to permanent vision loss: Frequency: Common in individuals with risk factors (e.g., older ...
Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye. [1] The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye.
A vision disorder is an impairment of the sense of vision. Vision disorder is not the same as an eye disease . Although many vision disorders do have their immediate cause in the eye, there are many other causes that may occur at other locations in the optic pathway.
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.
