1/16. Triangular transchamber suture.A 64-year-old woman with a fibrous membrane at the lens plane after traumatic loss of all the iris and massive intraocular hemorrhage had posterior chamber intraocular lens (PCIOL) implantation anterior to the fibrous membrane with a triangular transchamber suture to prevent possible PCIOL-corneal touch and enhance the stability of the PCIOL. After 3 years, the PCIOL remained in a good position and visual rehabilitation was satisfactory and without complications.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
2/16. Severe penetrating ocular injury from ninja stars in two children.The authors describe two cases of penetrating ocular trauma in children resulting from ninja stars. In the first case, despite a scleral laceration, loss of iris tissue, and a vitreous hemorrhage, the child had a good result with a final best corrected visual acuity of 20/20. Unfortunately, the child in the second case did not fare as well. In this case, the child suffered a large corneal laceration and traumatic cataract. He ultimately required a penetrating keratoplasty, and he is currently being treated for amblyopia, strabismus, and elevated intraocular pressures. His best corrected visual acuity is 20/70.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
3/16. iris prolapse in small incision cataract surgery.iris prolapse is a rare complication after small incision cataract surgery. We looked at the possible operative and perioperative factors that might have contributed to this complication in 2 of our patients and in another 10 patients identified through a national questionnaire survey. The details of 12 cases of iris prolapse following small incision cataract surgery are presented. Since iris prolapse may occur in small incision cataract surgery, notably in the presence of certain predisposing factors, extra diligence is required in wound construction and closure in high-risk patients.- - - - - - - - - - ranking = 2keywords = iris (Clic here for more details about this article) |
4/16. Epithelial ingrowth in a phakic corneal transplant patient after traumatic wound dehiscence.PURPOSE: To report a case of epithelial ingrowth (downgrowth) occurring in a phakic corneal transplant patient after traumatic wound dehiscence with iris prolapse that was successfully eradicated with early surgical intervention. methods: Interventional case report of a 70-year-old monocular, phakic patient who developed epithelial ingrowth within 1 week of repair of a traumatic penetrating keratoplasty wound dehiscence, with reposition of the iris that had been prolapsed for 36 hours. A gradually expanding membrane developed from the surface of the reposited iris, across the anterior lens capsule. argon laser photocoagulation applied to the surface of the iris confirmed the diagnosis and outlined the extent of the epithelial tissue on the iris. RESULTS: Intraoperative peeling of the epithelial membrane from the surface of the lens and excision of the involved iris were performed combined with extracapsular cataract extraction and insertion of a posterior chamber intraocular lens via an open-sky technique through a repeat penetrating keratoplasty opening in the cornea. This resulted in complete resolution of the intraocular epithelialization. Histopathologic examination of the excised tissue confirmed the diagnosis of epithelial ingrowth. CONCLUSIONS: Reposition of traumatically prolapsed iris tissue can result in epithelial ingrowth. Early aggressive surgical intervention can successfully remove all the epithelial tissue from within the anterior segment.- - - - - - - - - - ranking = 7keywords = iris (Clic here for more details about this article) |
5/16. Expulsion of an intraocular lens through a clear corneal wound.A 91-year-old man sustained blunt trauma to an eye that had uneventful phacoemulsification through a superior clear corneal incision 5 years earlier. The silicone foldable intraocular lens (IOL) and a portion of the iris and capsular bag were expulsed through the cataract excision, which then self-sealed. This case illustrates the potential for expulsion of foldable IOLs through small clear corneal incisions even several years after surgery.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
6/16. iris prolapse at the surgical site: a late complication of nonpenetrating deep sclerectomy.To investigate the occurrence and management of late-onset iris prolapse through the surgical wound after nonpenetrating deep sclerectomy. 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. The iris tissue bulge did not progress and there were no other complications. The visual acuity was not affected and the intraocular pressure was controlled with medical therapy. These cases demonstrate that the eye is weaker than normal at the surgical site after nonpenetrating deep sclerectomy, allowing iris protrusion. iris prolapse should be added to the list of late postoperative complications of nonpenetrating deep sclerectomy.- - - - - - - - - - ranking = 4keywords = iris (Clic here for more details about this article) |
7/16. Comeoscleral perforation after pterygium excision and intraoperative mitomycin C.A 28-year-old man underwent pterygium excision with a single intraoperative application of mitomycin C (0.02%) for 3 minutes. One week after the surgery, the patient developed a corneoscleral perforation with iris prolapse. To the best of our knowledge, corneoscleral melting in the first postoperative week after a single intraoperative application of mitomycin C has not been reported. Moreover, the perforation occurred despite using a minimum concentration of the drug, risk factors were absent, and the surgery was performed by an experienced surgeon. Although a single case, this report questions the safety of using an intraoperative application of mitomycin C for preventing a recurrence of pterygium.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
8/16. Complications of neodymium:YAG laser goniopuncture after deep sclerectomy.PURPOSE: To study the complications of neodymium:YAG (Nd:YAG) goniopuncture after deep sclerectomy with collagen implant (DSCI). methods: All patients who underwent a Nd:YAG goniopuncture after a successful DSCI for primary open-angle glaucoma were included in a non-randomized clinical study. RESULTS: Nd:YAG goniopuncture was performed in 31 patients. The mean time from surgery to goniopuncture was 3.2 /- 3.2 months. The mean intraocular pressure (IOP) before goniopuncture was 32.0 /- 10.8 mmHg (SD); the mean IOP 1-2 hours after goniopuncture was 16.5 /- 6.3 mmHg. After a mean follow-up of 5.4 /- 2.8 months, the mean IOP was 17.8 /- 11.6 mmHg. Three patients had a spontaneous iris prolapse after Nd:YAG goniopuncture and consequently high IOP. No signs of severe hypotension were observed. CONCLUSION: There are potentially serious complications relating to Nd:YAG goniopuncture after deep sclerectomy. However, further studies are needed to determine the safest time and level of IOP at which to perform Nd:YAG goniopuncture.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
9/16. Repair of a ruptured globe using topical anesthesia.We present a 76-year-old patient who had ocular trauma with dehiscence of the wound and scleral rupture with a prolapsed iris, ciliary body, intraocular lens, and vitreous after uneventful cataract surgery with a self-sealing sclerocorneal tunnel incision. General anesthesia was not possible because the patient had a history of lung cancer with extensive emphysema and unstable coronary disease. Local retrobulbar or peribulbar anesthesia was not considered because of the risk for further extrusion of intraocular contents. Topical anesthesia was applied with a 10.0 mm x 2.5 mm cellulose sponge soaked in oxybuprocaine 0.4% (Novesine) placed under the upper and lower lid for 20 minutes. Surgical repair of a 14.0 mm scleral wound was achieved without complication or pain during the procedure.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
10/16. Airbag-induced bilateral corneal graft dehiscence.PURPOSE: To report a case of bilateral corneal graft dehiscence caused by blunt trauma. methods: Case report of bilateral simultaneous corneal graft dehiscence with expulsion of the lens and iris as a result of airbag-induced trauma. RESULTS: Both corneal buttons were resutured, the prolapsed iris tissue was repositioned in the right eye, and anterior vitrectomy was performed bilaterally. Topical and systemic antibiotics, topical steroids, cycloplegic agents, and antiglaucoma drugs were initiated. Repeated B-scan ultrasound examinations demonstrated an attached retina in both eyes. Three weeks after admission, the right eye was reoperated for removal of remnant lens material and additional anterior vitrectomy. The patient was fitted with polycarbonate spectacles with an optical correction of 8 in both eyes. visual acuity improved to 20/200 and 0.5/60 in the right and left eyes, respectively. The right corneal graft regained transparency, but the left one remained hazy. CONCLUSION: Airbag deployment during motor vehicle collisions is a significant cause of ocular morbidity. The reported risk of airbag-related eye injury is 2.5% for any eye injury and 0.4% for severe eye injury. patients undergoing corneal surgery should be counseled about the weakness of the donor-recipient interface and should consider wearing protective glasses.- - - - - - - - - - ranking = 2keywords = iris (Clic here for more details about this article) |
