Surgical correction. Surgical correction of the hypertropia is desired to achieve binocularity, manage diplopia and/or correct the cosmetic defect. Steps to achieve the same depend on mechanism of the hypertropia and identification of the offending muscles causing the misalignment.
Common side effects are double vision, droopy eyelid, overcorrection, and no effect. The side effects typically resolve also within three to four months. Botulinum toxin therapy has been reported to be similarly successful as strabismus surgery for people with binocular vision and less successful than surgery for those who have no binocular vision.
Complications that occur rarely or very rarely following surgery include: eye infection, hemorrhage in case of scleral perforation, muscle slip or detachment, or even loss of vision. Eye infection occurs at a rate between 1 in 1100 and 1 in 1900 and can lead to permanent loss of vision if not properly treated. [15]
Sometimes surgery on more than one eye muscle is required. In some simpler, unilateral cases a single surgery may suffice. In these cases the main problem is that the inferior oblique muscle of the same eye acts unopposed by the weakened superior oblique muscle, pulling the eye up.
Prism correction. Prism lenses (here unusually thick) are used for pre-operative prism adaptation. Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions.
Treatment options include eye exercises, wearing an eye patch on alternative eyes, prism correction, and in more extreme situations, surgery or botulinum toxin. If your provider diagnoses swelling or inflammation of, or around the nerve, medicines called corticosteroids may be used.
Side effects. The most common side effects are droopy eyelids and over- or undercorrections; a further common side effects are diplopia and inadvertent vertical deviation (hypo- or hypertropia). The side effects typically resolve in 3–4 months.
If the residual esotropia is small, or if the patient is unfit or unwilling to have surgery, prisms can be incorporated into their glasses to provide more permanent symptom relief. When the deviation is too large for prismatic correction to be effective, permanent occlusion may be the only option for those unfit or unwilling to have surgery.
Consecutive: Consecutive hypermetropia occur due to surgical over correction of myopia or surgical under correction in cataract surgery. Functional: Functional hypermetropia results from paralysis of accommodation as seen in internal ophthalmoplegia, CN III palsy etc.
Symptoms. 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 ...
