1/27. Epithelial ingrowth of anterior chamber and anterior surface of vitreous.This study is a case report of the histopathologic findings of the anterior chamber epithelial ingrowth in a patient who had penetrating injury in the right eye from an arrow approximately 20 years ago. The patient underwent the enucleation in the right eye due to pthisis bulbi and was fitted with a prosthetic eye. Specimens were prepared from the enucleated right eye for histopathologic observation using hematoxyllin-eosin to be observed under light microscopy. Epithelial ingrowth in the anterior chamber was noted in one layer or multi-layered epithelial cell growth. The ingrowth had spread to the posterior surface of the cornea to the anterior chamber angle, to the iris surface, and to the anterior surface of the vitreous. The finding suggests that epithelial ingrowth could invade even through a perforation site and spread wherever the cells could reach.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
2/27. Caterpillar setae in the deep cornea and anterior chamber.PURPOSE:To report a case of caterpillar setae embedded in the deep cornea and anterior chamber. methods: A 26-year-old man was struck in his right eye by a caterpillar (Dendrolimus punctatus walker). Severe conjunctival injection, chemosis, and erosion of the cornea developed immediately. Numerous setae fragments were found to be embedded into the palpebral conjunctiva and deep cornea, extending into the anterior chamber near the anterior iris surface. RESULTS: After partial removal of the setae under a microscope, the inflammation subsided and visual acuity improved to RE: 20/20. CONCLUSION: Caterpillar setae are sharp enough to penetrate the cornea and extend into the anterior chamber.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
3/27. 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) |
4/27. Corneal laceration and intraocular foreign body in a post-LASIK eye.PURPOSE: To describe a case of full-thickness corneal laceration and intraocular foreign body in an eye that underwent laser-assisted in situ keratomileusis (LASIK). methods: A 43-year-old man underwent uneventful bilateral LASIK. Seventeen months after LASIK, the patient suffered penetrating trauma to the right eye while hammering metal without safety glasses. Examination on the night of the injury showed an uncorrected visual acuity of 20/30 in the right eye. Slit-lamp biomicroscopy showed a 2.4-mm full-thickness peripheral corneal laceration at the 11-o'clock position extending over the edge of the previous LASIK flap and a foreign body partially embedded in the superior iris. He was started on prophylactic topical and intravenous antibiotics. Under general anesthesia, the corneal laceration was repaired, and the intraocular foreign body was removed without any complications. RESULTS: At the follow-up visit 9 months after the surgery, the uncorrected visual acuity was 20/25 in the right eye. On slit-lamp examination, the corneal sutures and the well-positioned LASIK flap were in place. CONCLUSION: Penetrating trauma of the cornea did not lead to flap-related complications in this post-LASIK eye. Repair of the corneal laceration and removal of the intraocular foreign body after LASIK were managed without complications. Care must be taken to try not to manipulate or lift the LASIK flap during corneal laceration repair.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
5/27. Posttraumatic neovascularization in a cataractous crystalline lens.A 73-year-old woman presented with a dense traumatic cataract and intralens angiogenesis. Slitlamp examination showed abundant blood vessels in the lens stroma. Microscopic examination confirmed the presence of blood cells in the lumen. The angiogenesis represented an ingrowth into the lens from posterior synechias. Pathologic angiogenesis is frequently seen in the retina, vitreous, iris, and cornea but is rarely seen in the crystalline lens. This is the first well-documented case of angiogenesis in the lens stroma.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
6/27. Intraocular caterpillar setae without subsequent vitritis or iridocyclitis.PURPOSE: To report a case of caterpillar setae embedded in the corneal stroma and inferotemporal retina with minimal inflammation. DESIGN: Observational case report. methods: A 4-year-old boy developed a red eye after playing with a caterpillar. He was placed on topical tobramycin/dexamethasone and referred for evaluation of embedded setae in his conjunctiva, cornea, iris, and retina. Examination revealed no iridocyclitis or vitritis. RESULTS: Because of the lack of intraocular inflammatory response, no invasive intervention was conducted to remove or destroy the setae and he was tapered off the tobramycin/dexamethasone. At 4-month follow-up he remained asymptomatic with the setae still present in both his cornea and retina. In addition, vitreous membranes had formed in the immediate vicinity of the intraretinal setae. CONCLUSION: Intraretinal and corneal setae can be embedded with minimal inflammation and can be tolerated without need for surgical intervention.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
7/27. retinal detachment and phthisis bulbi after implantation of an iris prosthetic system.We report 2 eyes of 2 patients who developed persistent inflammation, hypotony, and total retinal detachment after secondary implantation of an iris prosthetic system (IPS) in association with cataract surgery. The first patient had an uneventful history of 16 years despite a retained intraocular glass foreign body and the second patient, of 38 years after sustaining penetrating corneoscleral injury with iris tissue loss. Both patients were thoroughly assessed clinically, and the enucleated globe in the first patient was examined by light microscopy. Both eyes had chronic inflammation with retrocorneal and cyclitic membrane formation around the artificial iris-lens diaphragm. These cases suggest that implantation of an IPS combined with cataract surgery can trigger decompensation of posttraumatic eyes that had been stable over a long period.- - - - - - - - - - ranking = 7keywords = iris (Clic here for more details about this article) |
8/27. Posttraumatic exogenous Nocardia endophthalmitis.PURPOSE: To report a case of posttraumatic exogenous Nocardia endophthalmitis. DESIGN: Interventional case report. METHOD: A 46-year-old man presented with counting fingers vision, severe eye pain, hypopyon, and an iris mass consistent with endophthalmitis following a penetrating injury to the left eye. RESULTS: Despite oral fluconazole and repeated intravitreal injections of vancomycin, gentamicin, and amphotericin b, the eye remained painful with a persistent hypopyon and recurrent iris masses. Cultures of the vitreous and iris masses remained negative for organisms. Despite vitrectomy and sector iridectomy of the iris mass with repeat injections of intravitreal antibiotics, the patient continued to have severe pain, poor vision, and developed new iris masses. Enucleation cultures confirmed nocardia asteroides. CONCLUSIONS: Posttraumatic exogenous Nocardia endophthalmitis is extremely rare, and its clinical signs can mimic a fungal infection.- - - - - - - - - - ranking = 5keywords = iris (Clic here for more details about this article) |
9/27. Pars plana vitrectomy foreign body extraction assisted with a 24-gauge needle tunnel.A 54-year-old man presented with corneal laceration, traumatized iris, small vitreous hemorrhage, lens opacity, and a 13-mm intraocular foreign body embedded in the retina. Pars plana vitrectomy and argon laser photocoagulation were performed. Using intraocular forceps, the object was forced into a 24-gauge needle that was inserted through the sclerotomy. The foreign body and the needle were removed from the eye. phacoemulsification with foldable intraocular lens implantation in the ciliary sulcus was performed. Seven days after the surgery, the patient's visual acuity was 20/20 with spectacle correction of -3.5 diopters. The use of a needle tunnel during pars plana vitrectomy should be considered in similar cases of large, irregular intraocular foreign bodies to avoid severe and irreversible damage to the adjoining tissues.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
10/27. 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) |
