1/627. Hypobaric ocular trauma from a Popper.We have observed 3 cases of ocular trauma in children that were caused by an atypical, hypobaric mechanism induced by a toy called a Popper. When we initially notified the united states consumer product safety Commission in 1990, Poppers disappeared from store shelves. We are concerned that this potentially harmful toy is making a comeback in 1998 (Smilemakers Inc, Spartanburg, SC; June-July 1998 catalog, p. 57). In 1990, packaged poppers cautioned against applying to face or skin; we are not sure that such warnings accompany current Poppers.- - - - - - - - - - ranking = 1keywords = trauma (Clic here for more details about this article) |
2/627. Epikeratoplasty for traumatic corneal ectasia.PURPOSE: To evaluate the efficacy of epikeratoplasty in a case of traumatic corneal ectasia. METHOD: Epikeratoplasty using a manually dissected donor lenticule was used to treat traumatic corneal ectasia after an iron nail injury. RESULT: No intra- or postoperative complication was encountered. At the end of 6 months' follow-up, the patient's best corrected visual acuity was 6/12. CONCLUSION: Epikeratoplasty is a useful technique to treat traumatic corneal ectasia.- - - - - - - - - - ranking = 1.4000633853028keywords = trauma, injury (Clic here for more details about this article) |
3/627. Paintball ocular injuries.INTRODUCTION: Six cases of ocular injury following paintball injuries sustained during war games are described. A CO2-powered rifle shoots a 14 mm plastic-coated paintball at participants. The muzzle velocity of the gun is 250 ft/sec (76 m/sec). Locally manufactured paintballs are harder than the more expensive imported varieties and may account for the severity of our reported injuries. METHOD: Six patients presented to a retinal specialist with various ocular injuries, predominantly of the posterior pole. RESULTS: All patients were young males. There were no cases of ocular penetration. A variety of retinal pathologies was noted, with three cases requiring surgery; however this did not significantly improve the visual outcome. CONCLUSIONS: These cases highlight the severe ocular injuries that may occur from paintball injuries. Recommendations to avoid ocular injury are made.- - - - - - - - - - ranking = 0.00012677060563719keywords = injury (Clic here for more details about this article) |
4/627. "The disappearing lens": failure of CT to image the lens in traumatic intumescent cataract.The CT scans of three patients whose eyes were lacerated by trauma failed to demonstrate the lens. A slit-lamp examination of those eyes clearly indicated that the lenses were present behind the iris but that they were swollen and opaque (intumescent cataract). Apparently, a shift of water into the injured lens had reduced the expected hyperdense CT image of the lens to a level that it was no longer discernible.- - - - - - - - - - ranking = 1keywords = trauma (Clic here for more details about this article) |
5/627. Repair of orbital floor fractures with hydroxyapatite block scaffolding.PURPOSE: To determine the efficacy of using a scaffold of hydroxyapatite blocks within the maxillary sinus to treat patients with large orbital floor fractures and secondary vertical globe dystopia. methods: Case series of five patients. Hydroxyapatite blocks were stacked within the maxillary antrum to support the reconstructed orbital floor. RESULTS: All patients had good results, though mild residual enophthalmos persisted in three patients. The orbital floor implants and globe positions remained stable during follow-up intervals ranging from 46 to 65 months. No adverse postoperative complications, such as sinusitis, developed. CONCLUSIONS: Hydroxyapatite block scaffolding is a useful alternative to metallic floor implants and autologous bone grafts in the reconstruction of large traumatic orbital floor defects associated with vertical globe dystopia.- - - - - - - - - - ranking = 0.2keywords = trauma (Clic here for more details about this article) |
6/627. Ocular explosion during cataract surgery: a clinical, histopathological, experimental, and biophysical study.INTRODUCTION: An increasing number of cases are being recognized in which a peribulbar anesthetic for cataract surgery has been inadvertently injected directly into the globe under high pressure until the globe ruptures or explodes. We reviewed the records of 6 such cases (one of which was reported previously by us), and one additional case has been reported in the literature. Surprisingly, 2 of these 7 cases went unrecognized at the time, and the surgeons proceeded with the cataract operation; all of the patients ultimately developed severe visual loss and/or loss of the eye. OBJECTIVES: To reproduce this eye explosion in a live anesthetized rabbit model and to perform a clinical, histopathological, experimental, biophysical, and mathematical analysis of this injury. methods: Eyes of live anesthetized rabbits were ruptured by means of the injection of saline directly into the globe under high pressure. The clinical and pathological findings of the ruptured human and animal eyes were documented photographically and/or histopathologically. An experimental, biophysical, and mathematical analysis of the pressures and forces required to rupture the globe via direct injection using human cadavers, human eye-bank eyes, and classic physics and ophthalmic formulas was performed. The laws of Bernoulli, LaPlace, Friedenwald, and Pascal were applied to the theoretical and experimental models of this phenomenon. RESULTS: The clinical and pathological findings of scleral rupture, retinal detachment, vitreous hemorrhage, and lens extrusion were observed. In the exploded human and rabbit eyes, the scleral ruptures appeared at the equator, the limbal area, or the posterior pole. In 2 of the 7 human eyes, the anterior segments appeared entirely normal despite the rupture, and cataract surgery was completed; surgery was canceled in the other 4 cases. In 4 of the 5 injected and ruptured rabbit eyes, the anterior segments appeared essentially normal. The experiments with human eye-bank eyes and the theoretical analyses of this entity show that the pressure required to produce such an injury is much more easily obtained with a 3- or 5-mL syringe than with a syringe 10 mL or larger. CONCLUSIONS: Explosion of an eyeball during the injection of anesthesia for ocular surgery is a devastating injury that may go unrecognized. The probability of an ocular explosion can be minimized by careful use of a syringe 10 mL or larger with a blunt needle, by discontinuing the injection if resistance is met, and by inspecting the globe prior to ocular massage or placement of a Honan balloon. When ocular explosion occurs, immediate referral to and intervention by a vitreoretinal surgeon is optimal. Practicing ophthalmologists should be aware of this blinding but preventable complication of ocular surgery.- - - - - - - - - - ranking = 0.00019015590845579keywords = injury (Clic here for more details about this article) |
7/627. Management of traumatic cyclodialysis cleft associated with ocular hypotony.BACKGROUND AND OBJECTIVE: To evaluate the efficacy of direct cyclopexy for treatment of traumatic cyclodialysis cleft associated with ocular hypotony. patients AND methods: Eyes with traumatic cyclodialysis cleft were treated with direct cyclopexy or 1.0% atropine eyedrop. RESULTS: Five eyes with a large cyclodialysis cleft were treated with direct cyclopexy. Postoperatively, these eyes obtained normal intraocular pressure. Four of the 5 eyes had good visual acuity, and 1 eye that had preoperative subretinal hemorrhage in the macula had poor visual acuity. Of the 3 eyes treated with 1.0% atropine eyedrops, 1 had good visual acuity, and 2 with retinal folds had fairly good and poor visual acuity. CONCLUSION: The present study showed that direct cyclopexy is useful for the treatment of traumatic cyclodialysis cleft associated with ocular hypotony, and that the cyclodialysis should be surgically treated before irreversible retinal folds develop.- - - - - - - - - - ranking = 1.4keywords = trauma (Clic here for more details about this article) |
8/627. Management of traumatic luxation of the globe. A case report.PURPOSE: To report the management of a patient who had LeFort type III fractures and traumatic luxation of the globe with avulsion of the optic nerve and all extraocular muscles except for the medial rectus. methods: Eight hours after the trauma, the detached and retracted superior and lateral recti muscles could be found and sutured to their original insertions. The inferior rectus could not be retrieved. RESULTS: Although the left eye had no light perception, most of its motility was restored resulting in an unblemished cosmesis. CONCLUSION: Avoiding primary enucleation helped to alleviate the psychological burden of the trauma on the patient. In case of the eventual development of phthisis bulbi, the patient will have a chance to be fitted with a prosthesis over his own eye with a resulting better motility.- - - - - - - - - - ranking = 1.4keywords = trauma (Clic here for more details about this article) |
9/627. Traumatic anterior lens dislocation: a case report.A 45-year-old man presented to the emergency department complaining of decreased vision and pain in the left eye after blunt trauma to the eye. On evaluation, the vision was limited to detecting hand motions, and the intraocular pressure was 37 mmHg. Secondary acute angle-closure glaucoma, with pupillary block due to anterior dislocation of the lens, was diagnosed. The intraocular pressure remained elevated after medical therapy, and the patient underwent intracapsular cataract extraction and anterior vitrectomy. The possibility of elevated intraocular pressure due to lens dislocation or other types of secondary glaucoma should be considered after blunt ocular trauma.- - - - - - - - - - ranking = 0.4keywords = trauma (Clic here for more details about this article) |
10/627. Posterior chamber intraocular lens dislocation with the bag.We report a rare case of a 46-year-old man presenting with a luxation of a posterior chamber intraocular lens (IOL) with the capsular bag after ocular contusion. Preoperative axial length was 36.58 mm. After trauma, pars plana extraction of the dislocated IOL inside the capsular bag was performed using a forceps. Capsular fibrosis had probably weakened the zonules, which were ruptured by the trauma. This observation confirms the necessity of a large continuous curvilinear capsulotomy and meticulous cleaning of the anterior and posterior capsules to minimize postsurgical fibrosis and capsule contraction.- - - - - - - - - - ranking = 0.95968363942113keywords = contusion, trauma (Clic here for more details about this article) |
