1/44. 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 = 1keywords = extraction (Clic here for more details about this article) |
2/44. 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 = 1keywords = extraction (Clic here for more details about this article) |
3/44. Traumatic cataract presenting with unilateral nasal hemianopsia.A 56-year-old man developed a nasal field defect in his left eye 3 months after a traumatic accident. An examination showed a posterior subcapsular cataract in the left eye with no neurologic deficits. Humphrey 24-2 visual field testing revealed a nasal hemianopsia in the left eye. After cataract extraction and intraocular lens implantation, the patient's visual field returned to normal. This case shows that a cataract can present with a localized visual field deficit, which may be corrected by cataract extraction.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
4/44. 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) |
5/44. Surgical treatment of penetrating orbito-cranial injuries. Case report.Penetrating orbital injuries are not frequent but neither are they rare. The various diagnostic and therapeutic problems are related to the nature of the penetrating object, its velocity, shape and size as well as the possibility that it may be partially or wholly retained within the orbit. The authors present another case with unusual characteristics and discuss the strategies available for the best possible treatment of this traumatic pathology in the light of the published data. The patient in this case was a young man involved in a road accident who presented orbito-cerebral penetration caused by a metal rod with a protective plastic cap. Following the accident, the plastic cap (2.5x2 cm) was partially retained in the orbit. At initial clinical examination, damage appeared to be exclusively ophthalmological. Subsequent CT scan demonstrated the degree of intracerebral involvement. The damaged cerebral tissue was removed together with bone fragments via a bifrontal craniotomy, the foreign body was extracted and the dura repaired. Postoperative recovery was normal and there were no neuro-ophthalmological deficits at long-term clinical assessment. Orbito-cranial penetration, which is generally associated with violent injuries caused by high-velocity missiles, may not be suspected in traumas produced by low-velocity objects. Diagnostic orientation largely depends on precise knowledge of the traumatic event and the object responsible. When penetration is suspected and/or the object responsible is inadequately identified, a CT scan is indicated. The type of procedure to adopt for extraction, depends on the size and nature of the retained object. Although the possibility of non-surgical extraction has been described, surgical removal is the safest form of treatment in cases with extensive laceration and brain contusion.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
6/44. Traumatic endophthalmitis caused by an erwinia species.A previously healthy 70-year-old white man sustained a plant injury to his left eye while gardening and was admitted here because of an ensuing perforated cornea and endophthalmitis. The lens was opaque and its anterior capsule was ruptured. culture of fluid obtained by anterior chamber paracentesis yielded a species of the erwinia herbicolalathyri group (enterobacter agglomerans). Thirty-seven days after a course of cefazolin and gentamicin therapy, corneal edema necessitated a planned extracapsular cataract extraction. The aqueous humor and lens again revealed the identical erwinia species in pure culture. The patient received another course of cefazolin and showed improvement after the lens aspiration.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/44. 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) |
8/44. Epilenticular intraocular lens implantation in traumatic cataract with a ruptured posterior capsule.PURPOSE: To present a case of rapidly progressing traumatic cataract caused by posterior capsule rupture after nonpenetrating ocular injury, as well as a surgical procedure to safely implant the intraocular lens in such a traumatized eye. methods: In a 23-year-old man with traumatic cataract and posterior lens capsule rupture, a one-piece polymethylmethacrylate IOL was implanted before cataract extraction into the ciliary sulcus in front of the cataractous lens. Subsequently, the cataract was removed by pars plana lensectomy. RESULTS: The surgery and postoperative course were uneventful. Postoperative visual acuity was 20/20. CONCLUSION: We present a method of intraocular lens implantation in cases of rapidly progressing traumatic cataract caused by posterior capsule rupture after a blunt ocular trauma.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/44. Successful surgical rehabilitation of children with traumatic corneal laceration and cataract.OBJECTIVE: To evaluate the visual and refractive outcome of corneal transplant surgery, cataract extraction, and intraocular lens (IOL) implantation in children with traumatic corneal laceration and cataract. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Five patients, 7 years of age or younger, who underwent penetrating keratoplasty, cataract extraction, and IOL implantation for traumatic corneal laceration and cataract were identified. MAIN OUTCOME MEASURES: Each case was analyzed retrospectively for the following factors: preoperative findings; surgical technique, including management of the posterior capsule; measurement of axial length and keratometry; calculation of IOL power, style, and type of IOL implanted; graft clarity; final visual acuity; and final refraction. RESULTS: The five children ranged from 3 to 7 years of age at the time of trauma. All had primary repair of their injury before referral. Each patient was observed for more than 2 years. Each had a posterior chamber IOL placed in the sulcus. After surgery, no severe complications were observed. The preoperative visual acuity ranged from 20/400 to light perception. After surgery, all five patients had clear grafts and an improved visual acuity ranging from 20/20 to 20/400. The final spherical refraction in each patient was within 3.75 diopters (D) of plano, with 1.50 to 3.25 D of cylinder. CONCLUSIONS: Successful surgical rehabilitation was accomplished in these patients. Despite their young age and the difficulty in determining IOL power, combining surgery and aggressive amblyopia therapy resulted in visual rehabilitation with refractions approaching emmetropia.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
10/44. Traumatic wound dehiscence following cataract surgery: a thing of the past?PURPOSE: This study compares the frequencies of traumatic wound dehiscence following extracapsular cataract extraction (ECCE) and following phacoemulsification through a self-sealing corneoscleral tunnel. methods: A retrospective review was performed of the surgical record at a British eye hospital from September 1986 to August 1993 and January 1996 to December 1998. Cases requiring surgical repair of wound dehiscence following cataract extraction were identified. The frequencies of traumatic wound dehiscence following ECCE and phacoemulsification were compared using a two by two contingency table (chi-square test). RESULTS: Twenty-one cases of traumatic wound dehiscence were identified following 5,600 ECCEs (0.4%). In 4,200 phacoemulsification procedures only one case of traumatic wound dehiscence was identified (0.02%) (p = 0.0006, OR 15.8, chi2 = 11.69). CONCLUSION: phacoemulsification through a self-sealing corneoscleral tunnel is associated with significantly less risk of traumatic wound dehiscence than is extracapsular cataract extraction. The case of wound rupture following phacoemulsification is discussed with reference to a mechanism for the injury.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
