Lens dislocation after strabismus surgery. 1979

H M Hittner

A case of lens dislocation complicating strabismus surgery is described. This complication following scleral perforation is extremely rare. The lens dislocation occurred in the direction of the connective tissue overlying the perforation site to which multiple cryoapplications had been made. Irrigation and aspiration of the clear lens followed by discission of the lens capsule was necessary because of progressive lens dislocation resulting in profound amblyopia. Accurate aphakic optical correction of the involved eye combined with vigorous occlusion of the fellow eye resulted in excellent visual acuity for both eyes. Cosmetic strabismus surgery was then performed. Continued intermittent occlusion of the fellow eye, combined with continued constant aphakic optical correction of the affected eye will be required. The affected eye will be carefully followed for the long-term complication of retinal detachment associated with connective tissue traction.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D007906	Lens Subluxation	Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.

D003261	Contact Lenses	Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999)	Lenses, Contact,Contact Lens,Lens, Contact
D004948	Esotropia	A form of ocular misalignment characterized by an excessive convergence of the visual axes, resulting in a "cross-eye" appearance. An example of this condition occurs when paralysis of the lateral rectus muscle causes an abnormal inward deviation of one eye on attempted gaze.

D000550	Amblyopia	A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications.

D012590	Sclera	The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the CANAL OF SCHLEMM.

D013285	Strabismus	Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target.
