Ophthalmic features and visual prognosis in the Treacher-Collins syndrome.

The ocular findings and visual prognosis were reviewed in 24 patients with the Treacher-Collins syndrome who were evaluated in the craniofacial clinic in the Division of Pediatric Ophthalmology at Children's Hospital of Philadelphia between 1980 and 1991. All patients had some abnormality. Vision loss was present in 37% of patients. Amblyopia was present in 33%, significant refractive errors were present in 58%, and anisometropia was documented in 17%. Strabismus was present in 37% and significant lid and adnexal abnormalities were seen in 96%. The prognosis for normal vision in at least one eye is good but vision loss secondary to amblyopia is more resistant to treatment owing to other medical problems and social concerns.

The use of hyaluronic acid during adjustable suture surgery.

We prospectively studied the force required to move an extraocular muscle after adjustable suture surgery with and without the perioperative use of hyaluronic acid (Healon). The 15 muscles that received hyaluronic acid averaged 15.0 g of force to move the muscle 2.0 mm which was significantly different than the average force of 36.15 g required for the 13 control muscles. The decreased force required to adjust the muscle along with potential antiinflammatory properties of hyaluronic acid make this a useful adjunct during adjustable suture surgery.

The ophthalmologic manifestations of the cardio-facio-cutaneous syndrome.

The cardio-facio-cutaneous (CFC) syndrome is an uncommon multiple congenital anomalies/mental retardation syndrome whose major manifestations are congenital heart defects, relative macrocephaly, stunted growth, ectodermal dysplasia, characteristic facial appearance, and psychomotor developmental delay. All described cases were sporadic and cytogenetically normal. We report three additional patients with this diagnosis. All three patients developed strabismus, requiring extraocular muscle surgery. Two of our patients also had nystagmus. Combining the 18 previously reported cases with our additional 3, 9 of 21 had strabismus, 10 of 21 had ptosis, and 6 of 21 had nystagmus. Ophthalmic craniofacial abnormalities of hypoplastic supraorbital ridges, prominent epicanthal folds, and antimongoloid slant of the palpebral fissures were also common features contributing to the characteristic facies described for this syndrome. The ophthalmologist could aid in the diagnosis and treatment of these patients because of the prominent ophthalmologic symptomatology of the CFC syndrome.

Ultrasonographic findings in ceftriaxone: associated biliary sludge and pseudolithiasis in children.

PURPOSE: To prospectively evaluate the incidence of biliary sludge and pseudolithiasis in children treated with ceftriaxone. MATERIAL AND METHODS: Thirty-three children (14 girls, 19 boys) treated with ceftriaxone for prophylaxis (n=13) or for an infection (n=20) were included in this study. The incidences of biliary sludge and pseudolithiasis were investigated using ultrasonography. The ultrasonographic evaluations were performed prior to and on the 4th-5th days and on the 8th-10th days of treatment. The patients who had biliary sludge or pseudolithiasis were followed up with ultrasonographic evaluation periodically until these pathological phenomena disappeared. RESULTS: Ceftriaxone was administrated intravenously at a dosage of 100 mg kg(-1) day(-1). Serial gallbladder sonograms were performed before treatment and on the 4th-5th and 8th-10th days of therapy. Nineteen children developed pseudolithiasis and sludge in the gallbladder, and all were asymptomatic. No significant differences were found between the patients with normal versus abnormal sonographic findings in regard to gender, age, duration of the therapy, oral restriction except the presence of surgery (P< 0.005). CONCLUSION: The combination of oral restriction and surgical procedures may be a causal factor in ceftriaxone-associated biliary pseudolithiasis. It is emphasized that when gallstone and/or sludge are detected in the gallbladder in children by ultrasonographic examination, the administration of ceftriaxone must be sought beyond other causative factors.

[Plasental chorioangioma (case report)]. / Plasenta koryoanjiyomu.

Placental chorioangioma is the most common benign tumor of placenta, encountered in approximately 1% of all pregnancies. Clinical manifestations are rare and usually associated with tumors greater than 5 cm in diameter. They include polyhydramnios, congestive heart failure, anemia, prematurity, growth retardation, and intrauterine fetal death. We report a case of chorioangioma of the placenta in which ultrasonography and Doppler ultrasonography findings were useful in establishing the prenatal diagnosis.

Association of intraocular pressure and myopia in children.

PURPOSE: While elevated intraocular pressure (IOP) is associated with myopia in adults, its potential influence on the growth of eyes in juveniles without glaucoma is controversial. To address this issue, a possible relation between IOP and refraction in children was sought. METHODS: A cross-sectional survey of IOP was conducted in children presenting to the Division of Pediatric Ophthalmology at The Children's Hospital of Philadelphia for a complete eye examination. Measurement of IOP was attempted in all children, including those with amblyopia, prematurity, and strabismus. Exclusion criteria were abnormalities of the posterior pole and/or conditions such as cataract that precluded assessment of refractive error. For analysis, myopia was defined as a spherical equivalent of more than 1 diopter (D) of myopia. Logistic regression was used to assess the association between other patient characteristics and presence of myopia. RESULTS: Intraocular pressure testing was attempted in all age groups, but was more successful in older children. Reliable readings were obtained on 321 subjects. The mean age was 9.8 years, with a mean IOP of 17.3 mmHg in the right eye and 17.2 mmHg in the left and a mean spherical equivalent of +0.2 D in the right eye and +0.1 D in the left. Increasing age, a family history of myopia, and amblyopia were associated myopia. Increasing IOP also was related to myopia. Even when patients with amblyopia, strabismus, and prematurity were exclude, age, family history of myopia, and IOP again were associated with myopia. CONCLUSIONS: These results indicate that IOP in children may be higher in myopic than nonmyopic eyes. Whether IOP could contribute to the mechanisms causing the abnormal eye growth of childhood myopia requires further study.
