Iris Prolapse

Prolapse of Iris


  • We present 2 strategies for managing IFIS-associated iris prolapse. Placement of a single subincisional iris retractor following reposition of the prolapsed iris was the more successful approach.[ncbi.nlm.nih.gov]
  • […] entry for "prolapse" is presented.[connection.ebscohost.com]
  • Abstract A theoretical explanation of the mechanism of iris prolapse is presented using simple flow mechanics and the Bernouille principle, which states that fluid pressure varies inversely to fluid velocity.[ncbi.nlm.nih.gov]
  • Two cases of iris prolapse that presented 8 and 10 months, respectively, after surgery for glaucoma were reviewed. One of the cases was associated with mild trauma. The postoperative follow-up was 5 and 24 months, respectively.[ncbi.nlm.nih.gov]
  • It is a relatively uncommon complication of present day cataract surgery, and it is postulated that iris prolapse results from transient pupillary block, in the post-operative period.[ncbi.nlm.nih.gov]
  • The puppy's eye was surprisingly quiet, but the prolapse was very fragile and was likely to start leaking causing collapse of the eye.[eastcottreferrals.co.uk]
  • […] pupil is a cardinal sign of a ruptured globe with the peak corresponding to the area where the iris has moved from the area of high pressure (intraocular) to low pressure (the environment outside the eye) to seal the perforation and prevent further collapse[healio.com]
  • In that situation, I sculpt as much as I can and make an enormous bowl that will then collapse upon itself. I can then use viscoelastic to viscodissect it from the posterior capsule.[reviewofophthalmology.com]
  • Here you can see a case of prolapse during irrigation aspiration. The first move is to decompress the anterior chamber from the paracentesis. 8.[eyesteve.com]
  • If iris prolapse occurs, the surgeon then aspirates fluid from the anterior chamber via a second incision site, in order to reduce the IOP.[medical-dictionary.thefreedictionary.com]
  • Key Words: Wound dehiscence, iris prolapse , phacoemulsification Incisions that are too large allow flattening of the anterior chamber during irrigation, aspiration, and the phacoemulsification process and this in turn increases the probability of iris[freethesaurus.com]
  • This can be done by lowering the intraocular pressure or bottle height and decreasing the aspiration flow rate/vacuum, which helps minimize large fluctuations in anterior chamber pressure and decreases the risk of repeat prolapse.[webeye.ophth.uiowa.edu]

Vascular Disease
  • Many disease states can affect the iris and its ability to maintain muscular tone and adaptability, such as diabetes, hypertension, vascular diseases, anterior uveitis/iritis, syphilis, neurological disease, trauma and other factors such as certain systemic[ophthalmologymanagement.com]
  • To excise, the prolapsed iris is cut flush with the corneal surface. The iris defect may be closed using a 10-0 polypropylene suture on a vascular needle.[emedicine.medscape.com]
  • Otherwise, it should be cut flush with the corneal surface.[crstoday.com]
  • “Take the phaco needle out of the eye and flush the tip, handpiece and tubing. Most of time I find the culprit is a piece of dense nucleus stuck in the tubing. ” Dr.[reviewofophthalmology.com]
  • ., in an eye with intraoperative floppy iris syndrome), if the I/A tip is withdrawn rapidly, the elevated IOP from the irrigation will result in a large pressure gradient with rapid fluid (and iris) egress.[eyeworld.org]
  • Because the IOP is elevated during I/A, fluid (and possibly the iris) will briefly but rapidly come out of the eye when the tip is withdrawn.[crstoday.com]
  • Stroke the main wound Use a hydrodissection cannula to gently stroke the cornea overlying the main wound.[webeye.ophth.uiowa.edu]
  • Gently stroke the main wound Tip #8 is to gently stroke the main wound with a cannula, which helps the iris be released back into the eye. 9.[eyesteve.com]
  • Acetylcholine is instilled through a paracentesis incision into the anterior chamber with gentle stroking of the iris. Acetylcholine constricts the pupil and may release the iris incarceration.[emedicine.medscape.com]

  • Here, we report a case of iris prolapse caused by blunt ocular trauma after NPT with sinusotomy and mitomycin C treatment.[ncbi.nlm.nih.gov]
  • To describe the visual rehabilitation after surgical treatment of an ocular injury sustained during an attack by a bird of prey.[ncbi.nlm.nih.gov]
  • When the iris prolapses out of the incision towards the end of the case, the best treatment is to lower the pressure behind the iris.[healio.com]

  • Anterior wound placement, clear of the iris plane, should help to prevent iris prolapse. Minimizing the irrigation velocity (and hence the fluid outflow velocity) should also help to prevent intraoperative prolapse.[ncbi.nlm.nih.gov]
  • Strategies for prevention and management include the use of pharmacological agents, ophthalmic viscosurgical devices, and iris retractors. These strategies can be augmented by alteration and adaptation of the surgeon's technique.[ncbi.nlm.nih.gov]
