1/1078. Cataracts, bilateral macular holes, and rhegmatogenous retinal detachment induced by lightning.

    PURPOSE: To report ocular injuries, including a unilateral rhegmatogenous retinal detachment, induced by lightning. METHOD: Case report. A 30-year-old man was injured by lightning. RESULTS: The patient developed a severe decrease in visual acuity in both eyes, an afferent pupillary defect in his left eye, bilateral cataracts, posterior vitreous detachments, macular holes, and an inferotemporal retinal detachment with an associated flap retinal tear in his left eye. CONCLUSIONS: This is a case of bilateral cataracts, posterior vitreous detachments, macular holes, and a unilateral retinal detachment associated with lightning. We postulate that the heating of the retinal surface, the concussive forces on the eye, and a sudden lateral contraction of the attached vitreous resulted in bilateral posterior vitreous detachments and a unilateral peripheral retinal break.

2/1078. siderosis bulbi resulting from an intralenticular foreign body.

    PURPOSE: To report a case of siderosis bulbi that resulted from a small intralenticular foreign body. METHOD: Case report. RESULTS: A 36-year-old man with normal visual acuity and a peripheral intralenticular iron foreign body in the left eye was treated conservatively. Nine weeks after the injury, he had ocular signs of siderosis bulbi, with changes in the electroretinogram. A clear lens aspiration with removal of the foreign body was performed. After removal of the iron foreign body, no progression or regression of the ocular signs of siderosis bulbi has occurred, and the electroretinogram has not changed over a 2-year period. CONCLUSIONS: Even in the presence of good vision, a patient with an intralenticular ferrous foreign body should be followed closely, and the foreign body should be removed before irreversible siderosis bulbi occurs.

3/1078. Cardiac involvement in proximal myotonic myopathy.

    Proximal myotonic myopathy (PROMM) is a recently described autosomal dominantly inherited disorder resulting in proximal muscles weakness, myotonia, and cataracts. A few patients with cardiac involvement (sinus bradycardia, supraventricular bigeminy, conduction abnormalities) have been reported. The cases of three relatives with PROMM (weakness of neck flexors and proximal extremity muscles, calf hypertrophy, myotonia, cataracts) are reported: a 54 year old man, his 73 year old mother, and 66 year old aunt. All three presented with conduction abnormalities and one had repeated, life threatening, sustained monomorphic ventricular tachycardia. This illustrates that severe cardiac involvement may occur in PROMM. ( info)

4/1078. Stability of vision during space flight in an astronaut with bilateral intraocular lenses.

    PURPOSE: To report excellent and stable vision in an astronaut during space flight after bilateral cataract surgery with intraocular lenses. methods: A 60-year-old physician mission specialist astronaut developed cataracts and underwent phacoemulsification with insertion of one-piece polymethylmethacrylate intraocular lenses that had 6-mm optics bilaterally. Several months later, he flew on a space shuttle mission. Ocular examinations were performed before and after the mission, and the patient was questioned about visual changes during flight. RESULTS: Ocular examinations demonstrated stable bilateral posterior chamber intraocular lenses. Our subject reported excellent vision during liftoff, 18 days of microgravity, changes in cabin pressure, and reentry. CONCLUSION: Results suggest that intraocular lenses are safe, effective, and well tolerated during space flight. ( info)

5/1078. Complete occlusion of the anterior capsular opening after intact capsulorhexis: clinicopathologic correlation.

    PURPOSE: To report histopathologic findings of capsule contraction syndrome with complete occlusion of the capsulorhexis opening. methods: Case report. In an 81-year-old woman, a complete occlusion of the anterior capsulorhexis opening developed 2 months after phacoemulsification and intraocular lens implantation. We surgically removed the contracted anterior capsule and analyzed the membrane by standard light microscopy and actin immunohistology. RESULTS: Light microscopic analysis of the membrane showed fibrous tissue subcapsularly with metaplastic lens epithelial cells. The contracted capsulorhexis opening was filled completely with proliferated actin-positive lens epithelial cells. CONCLUSIONS: Complete occlusion of the capsulorhexis opening can be attributed to excessive shrinkage of the capsule, probably caused by actin filaments found in the residual lens epithelial cells together with weak zonular support, and to the occlusion of the remaining central defect by massive proliferation of metaplastic lens epithelial cells.

6/1078. Early surgery and visual correction of an infant born with unilateral eye lens opacity.

    A healthy neonate born with unilateral cataract was operated upon on life Day 4. Visual correction and testing were initiated promptly. Resolution showed continuous improvement in the normal eye, with no improvement noted in the operated eye until adequate visual correction was provided. Following correction there was prompt marked improvement of visual resolution. ( info)

7/1078. 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.

8/1078. A slit-lamp needling filtration procedure for uncontrolled glaucoma in pseudophakic and aphakic eyes.

    In one aphakic and one pseudophakic patient without previous filtration surgery, a transconjunctival needling procedure similar to that used for failed filtration procedures was performed to create a filtering bleb. In both cases, intraocular pressure was successfully lowered for 6 months until the occurrence of bleb encapsulation, which was relieved by transconjunctival needling. There were no complications. In selected cases, this minimally invasive slit-lamp needling procedure provides successful filtration. ( info)

9/1078. The use of contact B mode ultrasound in pediatric ophthalmology.

    It has been shown that an ultrasound system such as the Bronson-Turner Contact B Mode can be added, fruitfully, to the armamentarium of the individual pediatric ophthalmologist. It can be used quickly and precisely with an ophthalmological training and without patient discomfort or anesthesia no matter what the age. Valuable anterior segment information can be readily gained without a waterbath. Examples are shown of children with opaque media who were found to have congenital cataracts and congenital aphakia, microphthalmos, PHPV, retinal anomalies and ectatic coloboma. ( info)

10/1078. Ocular pathology of Lowe's syndrome in a female infant.

    The ocular pathologic findings are presented in a case of a female infant with clinical and biochemical evidence of Lowe's syndrome. A small but increasing number of reports suggest that the mode of inheritance is not always sex-linked. The ocular histopathologic findings in the present case parallel those previously described for this syndrome. While the pathologic findings in other systems are variable, it is thought that the constellation of lens and anterior segment changes are sufficiently characteristic to identify cases of Lowe's syndrome.
