If they can't find a cause, your doctor might suggest certain exercises to help with your vertigo. There are specific routines that may help you improve uncomfortable vertigo symptoms and tolerate visual triggers better over time. Your doctor may also refer you to an audiologist or physical the...
The field of vision becomes narrower and is completely lost in later stages. These symptoms are because of the degeneration of the light-sensitive rods and cones of the retina. This process can continue for decades depending on the individual concerned. Figure 1 shows a photograph of a normal ...
Blurry vision, glare, and poor night vision are typical symptoms of cataracts. WebMD explains the condition with pictures including the causes, treatment options, and recovery.
Another common cause of visual difficulty is astigmatism, in which images are blurred due to an irregularly-shaped cornea. Astigmatism will eventually affect most people as a part of the aging process. It is treated with glasses, contact lenses, or refractive laser eye surgery. Color Blindness Th...
(C) Histogram showing refractive astigmatism before and after treatment Full size image All surgeries were uneventful, with no infection, inflammation, or intraoperative complications noted in any of the patients enrolled in the study. No eyes lost lines of CDVA at 3 months post-surgery. Binocular...
Exclusion criteria were previous ocular surgeries except for cataract surgery and refractive lens exchange, irregular corneal astigmatism of >1.0 diopter, and ocular pathologies or corneal abnormalities. Postoperative examinations were performed at 14 days and 3, 6, 12 months of surgery; the last ...
Anisometropia was defined as a difference in spherical equivalent between the two eyes of ≥ 0.50 Diopters (D), or a difference of astigmatism in any meridian ≥ 1.50 D56. Initial visual acuity was measured using an M&S logMAR chart. Inclusion criteria were: (i) presence of ...
Methods A total of 104 patients with a mean age of 29±6, treated with LASIK for myopia and astigmatism, were enrolled in a prospective study. High (90%) and low (10%) contrast visual acuity (CVA) were measured under photopic and scotopic conditions before surgery and at 3 months later...
Nevertheless, there were no notable disparities in the occurrence of visual symptoms across different forms of strabismus, as well as in relation to the severity of anisometropia and astigmatism. Table 4. Characteristics of symptomatic and asymptomatic groups in various characteristics. Characteristics...
The most common documented side effects for the targeted drug types were decreased or blurred vision (near or far), visual hallucinations, decreased accommodation, and eyelid/conjunctiva irregularities. In our sample, the most frequent ocular anomalies encountered were astigmatism (50% MI and 37.84% ...
