1/7. Anterior segment ischemia after strabismus surgery with microvascular dissection.Anterior segment ischemia is a rare but well-known complication of extraocular muscle surgery.(1) Several surgical techniques have been used to prevent this complication in high-risk patients. A number of studies have suggested that microvascular dissection and preservation of the anterior ciliary vessels during strabismus surgery may reduce the risk of ischemic complications. (2-4) We present a case in which anterior segment ischemia occurred despite the use of this vessel-sparing technique.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/7. Split rectus muscle modified Foster procedure for paralytic strabismus: a report of 5 cases.PURPOSE: To describe a new eye muscle surgical technique and its outcome in a small series of patients. methods AND STUDY: The Foster augmented rectus muscle transposition procedure, which utilizes posterior "lateral" fixation sutures [retroequatorial scleral myopexy parallel and adjacent to the lateral rectus muscle] to obtain greater effect from the transpositions, is modified, to preserve ciliary vessels, by doing only a partial 75-80% transposition of the rectus muscles, preserving and leaving behind a small portion of the muscle containing a ciliary vessel. RESULTS: In five patients in whom preserving ciliary vessel supply was particularly important, the procedure produced results in improving binocular alignment and motility equal to that of the unmodified Foster augmented transposition. There were no complications or undesirable results. CONCLUSION: The modified ciliary vessel preserving procedure can be applied in most cases and may be especially useful in those where this is a high likelihood of additional eye muscle surgery being necessary in the future.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
3/7. A case of intramuscular hemangioma presenting with large-angle hypertropia.PURPOSE: To report the case of a patient with large-angle hypertropia of an intramuscular hemangioma of the right superior rectus muscle (SR). methods: A 63-year-old man with progressive vertical deviation of the right eye for the past 6 months visited our strabismus department; his condition was not painful. An examination indicated that he had 60PD of right hypertropia at distance and near in primary gaze. Additionally, a significant limitation of his downgaze was noted. The right eye appeared mildly proptotic, and the upper and lower eyelids were slightly edematous. Corrected vision was 20/20 in both eyes. RESULTS: Orbital magnetic resonance imaging (MRI) studies revealed fusiform enlargement of the right superior rectus muscle, with prominent but irregular enhancement following gadolinium administration. Incisional biopsy revealed an intramuscular hemangioma in the superior rectus muscle with cavernous-type vessels. CONCLUSIONS: This case demonstrates that intramuscular hemangioma should be considered in the differential diagnosis of isolated extraocular muscle enlargement and unusual strabismus.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
4/7. A new mucolipidosis with psychomotor retardation, corneal clouding, and retinal degeneration.A man now 22 years of age had slow psychomotor development about 6 months after birth and developed intermittent corneal clouding at about 18 months. He developed truncal ataxia, hypotonia of the limbs combined with spasticity, and active deep reflexes. These have not progressed. His skeleton and facies are normal. Between his first and thriteenth year he developed sev ere optic atrophy, absence of retinal blood vessels, and an extinguished electroretinogram. Biochemical analysis of cultured fibroblasts indicated no lysosomal hydrolase deficiency; cellular metachromasia was absent and there was no mucopolysaccharidoses. Ultrastructural studies indicated single membrane vacuoles containing lamellated membranes and a polymorphous substance in tissue cultured cells and conjunctiva.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
5/7. Fetal alcohol syndrome.Significant alcohol ingestion during pregnancy can cause a spectrum of malformation of various degrees of severity in offspring. The full expression of "fetal alcohol syndrome" includes reduced growth, facial anomalies, and mental retardation. Affected infants are usually of near-term gestation, but small in weight and length. They continue to exhibit decreased growth postnatally. Mental retardation appears to be related to the degree of dysmorphic severity of appearance. It is primarily caused by central nervous system pathology rather than social environment. The most prevalent ophthalmologic finding in our series of a short horizontal palpebral fissure appears to be due primarily to a marked increased in intercanthal distances between the medial canthi (primary telecanthus) and to less extent mild displacement of the lateral canthi. Ptosis, often asymmetric, was noted in a number of patients. Comitant convergent strabismus was present in about 50% of our cases; a few had amblyopia. An important observation was the frequent and often high degree of myopia in these children. Low-incidence anomalies include corneal opacities (Peters anomaly in one), cataract, tortuosity of retinal vessels, and long eyelashes. Our findings plus many observations in the literature establish that children with fetal alcohol syndrome are at considerable risk for a variety of eye problems.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
6/7. optic nerve hypoplasia.optic nerve hypoplasia is rarely met in otherwise normal eyes. Three unilateral cases of patients with small optic disks, reduced visual acuity, and convergent squint on the affected eye are presented. The anomaly is probably caused by failure of development of the ganglion cell layer of the retina causing a small optic nerve head with normal central vessels. Inheritance or induction by drugs could not be found in our cases.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
7/7. Nasal heterotopia of the macula with persistent hyaloid vessel.A 22-year-old woman presented with nasal dragging of the disc and nasal ectopia of the macula due to persistent hyaloid vessels. The causes of this entity are presented. patients with strabismus should have ophthalmoscopic fundus exam to rule out ectopic maculae.- - - - - - - - - - ranking = 2.5keywords = vessel (Clic here for more details about this article) |
