Anterior lens luxation in a dog Anterior lens luxation with cataract formation in a cat. Ectopia lentis is a displacement or malposition of the eye's lens from its normal location. A partial dislocation of a lens is termed lens subluxation or subluxated lens; a complete dislocation of a lens is termed lens luxation or luxated lens.
Uveitis–glaucoma–hyphaema (UGH) syndrome, also known as Ellingson syndrome, is a complication of cataract surgery, caused by intraocular lens subluxation or dislocation. The chafing of mispositioned intraocular lens over iris, ciliary body or iridocorneal angle cause elevated intraocular pressure (IOP) anterior uveitis and hyphema. It is ...
Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma. The angle-closure glaucoma can be caused by a swollen or dislocated lens.
An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or false
Exfoliation syndrome: Exfoliation syndrome is a classic cause of secondary open-angle glaucoma, a common symptom of exfoliation syndrome is a cloudy layer on the anterior lens capsule. [ 2 ] Aphakic and pseudophakic glaucoma: Aphakic glaucoma is a common side-effect of cataract surgery which causes an increase in IOP.
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema; it is also associated with increased risk of endophthalmitis and retinal detachment.
Iridodonesis (/ ˌ aɪər ɪ d oʊ d oʊ ˈ n iː s ɪ s /) is the vibration or agitated motion of the iris with eye movement. [1] This may be caused by lens subluxation, [2] the incomplete or partial dislocation of the lens; or by aphakia, the absence of a lens.
PEX flakes by themselves do not directly cause glaucoma, but can cause glaucoma indirectly by blocking the outflow of aqueous humor, which leads to higher intraocular pressure, and this can cause glaucoma. [4] PEX has been known to cause a weakening of structures within the eye which help hold the eye's lens in place, called lens zonules. [2]
