Diplopia, or double vision, occurs commonly after strabismus surgery. Although the surgery can be used to treat some types of double vision, it can instead end up making existing symptoms worse or create a new type of double vision. The type of double vision can be horizontal, vertical, torsional, or a combination.
Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
Functional Endoscopic Sinus Surgery is considered a success if most of the symptoms, including nasal obstruction, sleep quality, olfaction and facial pain, are resolved after a 1-2 month postoperative healing period.
Surgeons can remove or peel the membrane through the sclera and improve vision by 2 or more Snellen lines. Usually the vitreous is replaced at the same time with clear (BSS) fluid, in a vitrectomy. Surgery is not usually recommended unless the distortions are severe enough to interfere with daily living.
There is no statistically significant difference in seizure-free rates between the four different types of surgeries: Hemispherotomy, functional hemispherectomy, anatomical hemispherectomy and hemidecortication. The overall rate of seizure freedom is estimated to be 73.4%. [7]
MeSH. D020731. MedlinePlus. 007018. [ edit on Wikidata] Laser-Assisted in Situ Keratomileusis ( LASIK ), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea. [1]
Also called double vision, it is a loss of visual focus under regular conditions, and is often voluntary. However, when occurring involuntarily, it results from impaired function of the extraocular muscles , where both eyes are still functional, but they cannot turn to target the desired object. [2]
It can be addressed with further surgery or with vision therapy; vision therapy has shown promising results if the consecutive exotropia is intermittent, alternating, and of small magnitude. (Consecutive exotropia may however also spontaneously develop from esotropia, without surgery or botulinum toxin treatment.
Contoura Vision is the only technology where consistent success beyond 20/20 vision has been achieved in the majority of patients. More than 40% of the patients that were evaluated were able to read one line on the visual acuity chart more than a person with 20/20 vision, and 13.5% could read two additional lines.
In several cases of double vision, once the underlying cyclotropia was identified, the condition was solved by surgical cyclotropia correction. Conversely, artificially causing cyclotropia in cats leads to reduced vision acuity, resulting in a defect similar to strabismic amblyopia.
