1/21. eye injuries associated with paintball guns.AIMS: This study identifies the various types of ocular injuries sustained after blunt trauma with a paintball fired from a paintball gun. methods: We report two patients who sustained injury to an eye after being shot with a paintball and review similar cases presented in the world literature. The type of injury sustained and the final visual acuity obtained after a paintball hit to the eye are examined. RESULTS: The two boys presented were hit in the eye with a paintball resulting in lens subluxation, hyphema formation, and angle recession. cataract extraction was required in both cases. One boy also had an optic neuropathy and a choroidal rupture. A review of the literature reveals a variety of injuries occur after a paintball hit to the eye. In some of the cases, the damage to the eye has led to loss of vision and at times loss of the eye. CONCLUSIONS: Paintball guns can cause devastating ocular injuries. Wearing protective eye and face gear during this game is essential. We recommend that an anti-fog face mask with a one-piece polycarbonate eye shield be worn by those participating in paintball games.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/21. Late traumatic wound dehiscence after phacoemulsification.Scars from scleral tunnel or clear corneal incisions for phacoemulsification should theoretically be stronger than the larger incisions of planned extracapsular cataract extraction. They should also be more resistant to blunt trauma. We present a case of scleral tunnel wound dehiscence and expulsion of a posterior chamber silicone intraocular lens after blunt trauma.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/21. Recurrent hyphema in an aphakic child: Swan syndrome.In 1973, Swan described 3 patients who developed hyphema months to years after uncomplicated cataract surgery. He noted focal vascularization from an ingrowth of episcleral vessels at the cataract wound site, resulting in recurrent intraocular bleeding. Swan syndrome has been reported following intracapsular cataract extraction, extracapsular cataract extraction (including clear corneal incisions), iridocyclectomy, and glaucoma filtering procedures. patients typically present with sudden painless blurred vision, often upon awakening, which may or may not be preceded by physical strain or trauma. Other patients are asymptomatic and diagnosed with hyphema or anterior chamber red blood cells on routine examination. The hyphema often resolve spontaneously, making later diagnosis difficult. Gonioscopic visualization of the abnormal wound vessels is necessary for diagnosis. Without active bleeding, however, the fibrovascular tuft may be easily overlooked. We report a case of Swan syndrome in a 16-month-old boy after cataract extraction was performed. To our knowledge, Swan syndrome has not been reported in the pediatric population. Children represent a significant proportion of patients undergoing anterior segment surgery and Swan syndrome should be considered in the differential diagnosis of hyphema in this population.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
4/21. anterior chamber hemorrhage during cataract surgery in Lowe syndrome.This article reports a spontaneous intracameral bleeding at the end of cataract surgery in both eyes of two patients with Lowe syndrome. Extracapsular cataract extraction with anterior vitrectomy and posterior capsulotomy, using the anterior chamber maintainer (ACM), was performed in both eyes of two patients. At the conclusion of the surgery, when the ACM was removed, spontaneous bleeding occurred into the anterior chamber and spread into the vitreous cavity. The hemorrhage resolved spontaneously over varying periods of time. We propose that bleeding occurred from damage to iris vessels in the abnormal angle in our patients with Lowe syndrome when the ACM was removed with a concomitant decrease in intraocular pressure.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/21. Rubeosis capsulare.Two patients with diabetes had extracapsular cataract extraction with intraocular lens (IOL) implantation. Both developed rubeosis iridis and neovascularization within the lens capsule supporting the IOL, a condition we have termed rubeosis capsular. argon laser treatment was ineffective in both patients. One patient was successfully treated by virectomy with endophotocoagulation. The other patient had a vitrectomy which was followed by a fibrinoid reaction, continued inflammation, rubeosis, and phthisis bulbi.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/21. 'In-the-bag' hyphaema--a rare complication of posterior chamber lens implantation.A 72-year-old woman developed a hyphaema on the first postoperative day after a combined trabeculectomy and extracapsular cataract extraction with posterior chamber intraocular lens implantation. On the second day the blood had redistributed to accumulate 'in the bag' posterior to the intraocular lens and had formed a fluid level. Postural drainage helped to clear the hyphaema from both locations, with no short-term effect on visual function or the filtering bleb.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/21. Delayed microhyphaema with intraocular lenses: a retrospective study of eight patients.Eight patients with delayed microhyphaema were identified from a computer data base of 1209 patients who had had cataract extraction with Binkhorst 4-loop intraocular lens insertion. Five cases were recurrent. The cases were examined to try and identify an underlying cause. No single cause was identified, but trauma, hypertension, and oral anticoagulants were found to be associated. Some episodes were asymptomatic. The wide variety of surgical technique and style of lens with which this complication has been reported implies multiple causative factors. The source of the bleeding and its management are discussed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/21. Unplanned extracapsular cataract extraction in postvitrectomy eyes.A 70-year-old man, a 59-year-old woman, and a 57-year-old woman underwent pars plana vitrectomy. In all three cases, cataracts developed in the eyes that had been operated on. During cataract extraction, which included massage of the globe after retrobulbar anesthesia and a conventional ab externo incision, loss of lens material into the vitreous cavity occurred in all three postvitrectomy eyes.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
9/21. Staphyloma: a complication of surgery for hyphema.Anterior staphylomas developed in two young patients as a postoperative complication of hyphema extractions through corneoscleral sections. The patients, aged five and nine years, underwent evacuation of the hyphemas after rebleeding caused medically unmanageable intraocular pressure elevations. Postoperatively, both patients received corticosteroids and had elevation of intraocular pressure. To repair the staphyloma, a scleral overlay patch graft was performed in one patient, but the intraocular pressure remained elevated and the staphyloma gradually recurred. Enucleation of the eye was eventually required. Resection of the staphylomatous area with lensectomy and complete vitrectomy was performed in the second patient. After four years of follow-up this patient continues to do well.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/21. Intraocular lens implant exchange and resolution of cystoid macular edema.Cystoid macular edema is a recognized complication of cataract extraction and intraocular lens implantation with an incidence of 5.2% to 50.0%. We have recently performed lens implant exchange in an eye with cystoid macular edema which suffered recurrent hyphema (UGH syndrome). In addition to resolution of the patient's recurrent hyphema, we observed the resolution of cystoid macular edema in this eye.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
