Strabismus surgery (also: extraocular muscle surgery, eye muscle surgery, or eye alignment surgery) is surgery on the extraocular muscles to correct strabismus, the misalignment of the eyes. [1] Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ...
Strabismus surgery requires an operating room, anesthetist, and other personnel, whereas bupivacaine injection in cooperative adults is an office procedure taking only a few minutes. Bupivacaine injection is not effective in paralyzed or atrophic muscles, or where there are restrictions to movement elsewhere in the orbit (e.g., fibrotic muscles ...
An excessive bleeding that cannot be stopped makes an enlargement of the cuts necessary to cauterize the vessel. Usually, a conversion to a limbal opening as in classical strabismus surgery can be avoided. There are few reports, though, on complications that are unique to MISS. [15]
Strabismus surgery attempts to align the eyes by shortening, lengthening, or changing the position of one or more of the extraocular eye muscles. The procedure can typically be performed in about an hour, and requires about six to eight weeks for recovery.
This also means that adults (and older children) have a higher risk of post-operative diplopia after undergoing strabismus surgery than young children. Patients who have undergone strabismus surgery at a young age often have monofixation syndrome (with peripheral binocular fusion and a central suppression scotoma).
In a small-scale study, adults whose reading difficulties due to convergence insufficiency had been unsuccessfully addressed by convergence exercises, base-in prism glasses or strabismus surgery showed improved reading after botulinum toxin therapy, maintaining improved reading remaining also after six months.

Complications: Accommodative dysfunction, binocular dysfunction, amblyopia, strabismus [3] Causes: Axial length of eyeball is too short, lens or cornea is flatter than normal, aphakia [2] Risk factors: Ageing, hereditary [2] Diagnostic method: Eye exam: Differential diagnosis: Amblyopia, retrobulbar optic neuropathy, retinitis pigmentosa sine ...
Nearly all ocular surgeries viz keratoplasty, cataract extraction, glaucoma surgery, iridectomy, strabismus, [5] retinal detachment surgery etc. can be done under regional anaesthesia. Conjunctiva, globe and orbicularis can be paralysed using a combination of surface anaesthesia, facial anaesthesia and retrobulbar block. [1]
