Strabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. [2] The eye that is pointed at an object can alternate. [ 3 ] The condition may be present occasionally or constantly. [ 3 ]
Conductive keratoplasty (CK): Conductive keratoplasty is a non laser refractive procedure used to correct presbyopia and low hypermetropia (+0.75D to +3.25D) with or without astigmatism (up to 0.75D). [22] [25] It uses radiofrequency energy to heat and shrink corneal collagen tissue.
Against-the-rule astigmatism – the horizontal meridian is steepest (a rugby ball or American football standing on its end). [17] Oblique astigmatism – the steepest curve lies in between 120 and 150 degrees and 30 and 60 degrees. [17] Irregular astigmatism – principal meridians are not perpendicular.
Strabismus, sometimes also incorrectly called lazy eye, is a condition in which the eyes are misaligned. [16] Strabismus usually results in normal vision in the preferred sighting (or "fellow") eye (the eye that the person prefers to use), but may cause abnormal vision in the deviating or strabismic eye due to the difference between the images ...
Strabismus can occur due to problems with the muscles and nerves that control the eyes, as a side effect of an eye injury or other medical condition, or as a complication from significant far ...
Anisometropia is caused by common refractive errors, such as astigmatism, far-sightedness, and myopia, in one eye. [6] Anisometropia is likely the result of both genetic and environmental influences. [7] Some studies suggest, in older adults, developing asymmetric cataracts may cause worsen anisometropia.
Astigmatism is when the refractive power of the eye is not uniform across the surface of the cornea because of asymmetry. In other words, the eye focuses light more strongly in one direction than another, leading to distortion of the image.
In general, strabismus can be approached and treated with a variety of procedures. Depending on the individual case, treatment options include: Correction of refractive errors by glasses; Prism therapy (if tolerated, to manage diplopia) Vision Therapy; Patching (mainly to manage amblyopia in children and diplopia in adults) Botulinum toxin ...
