1/154. A case of an intraocular foreign body due to graphite pencil lead complicated by endophthalmitis.We report a case of an 8-year-old boy who presented with an intraocular foreign body composed of graphite pencil lead. The patient had been accidentally poked in the right eye with a graphite pencil. Primary care consisted of corneal suturing and lens extraction. Two pieces of the pencil lead remained in the vitreous cavity following surgery, and 2 days later the patient developed endophthalmitis. Pars plana vitrectomy was performed immediately and the intraocular foreign bodies were removed through the scleral wound. Cultures of the vitreous fluid revealed no bacterial organisms. X-ray fluoroscopic analysis of the vitreous detected 1 ppm of aluminum (a constituent of the pencil lead). Although the clinical presentation indicated probable bacterial endophthalmitis, the detection of elemental aluminum within the vitreous cavity also suggested the possibility of further retinal toxicity due to some dissolving of the pencil lead.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/154. Surgically induced necrotizing scleritis in a patient with ankylosing spondylitis.We present the case of a 75-year-old man with ankylosing spondylitis who developed surgically induced necrotizing scleritis (SINS) more than 3 years after uneventful extracapsular cataract extraction and posterior chamber intraocular lens implantation. The patient presented with a painful eye and increasing vertical diplopia. To our knowledge, neither the association of SINS and ankylosing spondylitis nor vertical diplopia as its presenting complaint has been described.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/154. Posterior capsule opacification and wrinkling in a case of capsular bag distension.We describe a complication following anterior neodymium: YAG laser capsulotomy in a case of capsular bag distension which was diagnosed 21 months after cataract extraction with phacoemulsification and in-the-bag lens implantation. An anterior neodymium: YAG capsulotomy was performed and immediately after this the posterior capsule collapsed and wrinkled, causing a marked decrease in visual acuity that necessitated posterior neodymium: YAG capsulotomy.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/154. cataract extraction and intraocular lens implantation in anterior megalophthalmos.This report describes the implantation of a standard posterior chamber intraocular lens (IOL) in a patient with bilateral cataract and anterior megalophthalmos. After extracapsular cataract extraction, the IOL was sutured to the posterior surface of the iris and anterior capsule. Different types of IOLs were used in each eye, and the surgical technique was adapted to the characteristics of the IOL. No complications were noted. Visual rehabilitation was successful. Extracapsular cataract extraction with a posterior chamber IOL sutured to the posterior surface of the iris and anterior capsule is a useful option in patients with anterior megalophthalmos and cataract.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |
5/154. Electric cataract: a case report and review of the literature.A case of electrically induced cataract in both eyes in a 12-year-old boy, after a high-voltage electric shock, is reported. He sustained skin burns on the neck, chest, abdomen, and inner left arm. The cataract developed first in the left eye and later on in the right eye. The child regained normal vision in both eyes after cataract extraction and aphakic correction with spectacles. The need for awareness of the possibility of this complication and screening of all cases of electrical injuries is stressed. The majority of cases respond well to surgery, but final visual acuity will depend on the other ocular damage due to electrical current. The clinical features and pathogenesis of this condition are briefly reviewed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/154. 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) |
7/154. 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) |
8/154. In-the-bag secondary intraocular lens implantation in children.BACKGROUND: Surgery for congenital cataracts in early infancy usually includes a primary posterior capsulectomy and an anterior vitrectomy. Initially, most of these infants have aphakia after surgery. Over time, remaining equatorial lens epithelial cells produce new cortical fibers, resulting in a ring of cortex trapped between the lens equator and the fused anterior and posterior capsulectomy edges. A potential space is maintained between the anterior and posterior capsular leaflets. We describe a technique for placing a secondary intraocular lens (IOL) within the capsular bag. patients AND methods: Eight children, ranging in age from 11 months to 14 years, who originally had aphakia after cataract extraction were operated on with the intent to reopen the capsular bag and place an IOL in the bag. RESULTS: Secondary in-the-bag IOL implantation was successfully completed in 7 of 8 children. This was accomplished by reopening the capsular bag 360 degrees at the edge of the fused anterior and posterior capsulectomy remnants, using the previously published vitrectorhexis technique. Residual cortical material was aspirated, and an IOL was placed within the capsular bag. In 1 child, aged 14 years, the capsular bag was reopened, but the lens was placed in the ciliary sulcus because the new anterior capsule edge could not be visualized for 360 degrees . CONCLUSION: Placement of secondary IOLs within the capsular bag can be accomplished successfully for selected patients in the pediatric population. Surgeons operating on infantile cataracts without primary IOL placement can facilitate capsular IOL sequestration later by limiting the anterior and posterior capsulectomy to 4 to 5 mm and performing a generous anterior vitrectomy to help prevent secondary closure of the smaller capsulectomy.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/154. Refractive error in cataract surgery after previous refractive surgery.Bilateral cataract extraction with posterior chamber intraocular lens (IOL) implantation was performed in a patient after previous photorefractive keratectomy, radial keratotomy (RK) combined with astigmatic keratotomy, and retreatment of RK. Significant hyperopic error was observed after cataract surgery, and the IOLs were eventually exchanged in both eyes. A review of this case found that the refractive error was smaller when a refraction-derived keratometric value was selected for IOL power calculation. Nevertheless, hyperopic error still occurred.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/154. Spontaneous regression of Elschnig pearl posterior capsule opacification.After extracapsular cataract extraction with in-the-bag intraocular lens implantation, a 72-year-old woman had reduced visual acuity from posterior capsule opacification (PCO) resulting from Elschnig pearl proliferation. No capsulotomy was performed, and the PCO decreased spontaneously over time, improving visual acuity and leaving a clear capsule.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
