A spasm of accommodation (also known as a ciliary spasm, an accommodation, or accommodative spasm) is a condition in which the ciliary muscle of the eye remains in a constant state of contraction. Normal accommodation allows the eye to "accommodate" for near-vision. However, in a state of perpetual contraction, the ciliary muscle cannot relax ...
Cycloplegia is paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation. [1] Because of the paralysis of the ciliary muscle, the curvature of the lens can no longer be adjusted to focus on nearby objects.
Iridodialyses are usually caused by blunt trauma to the eye, [2] but may also be caused by penetrating eye injuries. [7] An iridodialysis may be an iatrogenic complication of any intraocular surgery [10] [11] [12] and at one time they were created intentionally as part of intracapsular cataract extraction. [13]
The first surgical procedures to reduce intraocular pressure of the eye, by decreasing production of aqueous humor, by damaging the ciliary body by diathermy, penetrating cyclodiathermy or surgical excision was done in the early twentieth century. [1] Cyclodestruction by diathermy was first performed by Weve in 1933. [11]
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 ...
A 2019 Cochrane Review found that individuals who receive iStents in combination with cataract surgery may be less likely than those who only receive cataract surgery to need glaucoma eye drops at medium-term follow-up; however, the evidence for this finding was of low quality. [18]
The most common strabismus finding is large angle exotropia which can be treated by maximal bilateral eye surgery, but due to the progressive nature of the disease, strabismus may recur. [14] Those that have diplopia as a result of asymmetric ophthalmoplegia may be corrected with prisms or with surgery to create a better alignment of the eyes.
Changes in contraction of the ciliary muscles alter the focal distance of the eye, causing nearer or farther images to come into focus on the retina; this process is known as accommodation. [1] The reflex, controlled by the parasympathetic nervous system , involves three responses: pupil constriction, lens accommodation, and convergence.
