Sensorimotor outcomes in children with prenatal exposure to methadone.

PURPOSE: To report the presentation and characteristics of strabismus in children with prenatal methadone exposure. METHODS: The medical records of children with prenatal methadone exposure were retrospectively reviewed. Those who were evaluated by pediatric ophthalmology were included. Information on the timing and types of prenatal exposure by trimester of pregnancy was then collected from the patients' mothers' charts. The children's perinatal histories and ophthalmologic findings were collected from their pediatric clinic charts and ophthalmology clinic charts, respectively. RESULTS: A total of 210 children with prenatal methadone exposure were identified, of whom 32 (15.2%) underwent eye examinations and 21 (10%) had strabismus. Five patients had esodeviations, with a mean age of onset of 11.6 months; 16 had exodeviations, with a mean age of onset of 6.8 months. Three patients with strabismus were born prematurely, and 2 had intracranial disease. Two patients underwent strabismus surgery. CONCLUSIONS: The incidence of strabismus in patients with prenatal methadone exposure was higher than in the general population (10% vs 3%-4%). Intermittent exotropia was the most common type of strabismus and presented earlier than in the general population, with no association with other systemic disease. Prenatal exposure to methadone was likely confounded by exposure to other substances, environmental factors, and genetics. Poor compliance with follow-up reduced the power of the study.

Localization and Retrieval of an Eyelid Metallic Foreign Body With an Oscillating Magnet and High-Resolution Ultrasonography.

A patient was found to have a metallic foreign body in the left anterior orbit on CT imaging, but the foreign body was not evident on clinical examination. On high-resolution ultrasonography, an object was identified in the left upper eyelid; however, the typical shadow with metallic foreign bodies was not seen. A high-power oscillating magnet was then applied to the eyelid, which revealed a subcutaneous metallic foreign body in the left upper eyelid. When used in conjunction, the high-resolution ultrasound and oscillating magnet successfully localized and facilitated retrieval of the metallic foreign body from the left upper eyelid.

Ophthalmic manifestations of cherubism.

Cherubism is a rare craniofacial disorder characterized by progressive replacement of mandibular and maxillary bone with multicystic fibro-osseous tissue, potentially resulting in significant deformity and morbidity. The severity of the disorder is variable; more advanced disease may affect the orbit and impact vision. We detail the ophthalmological findings in 2 patients, 7 and 8 years of age, with cherubism.

Rectus muscle resection in Graves' ophthalmopathy.

BACKGROUND: In the treatment of Graves' ophthalmopathy, rectus muscle resections generally are avoided because of the concern of reaggravating inflammation and creating excessive extraocular muscle restriction. In patients with large-angle strabismus and in patients with residual strabismus after maximal recession surgery, however, rectus muscle resection may be considered. We report a series of 8 patients with Graves' ophthalmopathy who underwent rectus muscle resections. METHODS: The records of 270 patients with Graves' ophthalmopathy who had undergone strabismus surgery were retrospectively reviewed. Data from subjects who had undergone rectus muscle resections were collected, including age at surgery, duration of disease, duration of diplopia, previous eye or strabismus surgeries, history of radioactive iodine or corticosteroid treatment, current thyroid medications, current use of corticosteroids, tobacco use, and signs and symptoms used to diagnose Graves' ophthalmopathy. RESULTS: Eight patients (5 females) were identified (mean age, 51.1 ± 17.6 years). Preoperatively, 4 patients had a horizontal deviation and 4 patients had both horizontal and vertical deviations in primary gaze. Mean preoperative horizontal deviation was 27.9(Δ) ± 15.2(Δ) and mean vertical deviation was 6.3(Δ) ± 5.4(Δ). At final follow-up examination, 7 patients were orthotropic in primary gaze; 1 patient had a larger deviation from slippage as the result of a broken suture within the first postoperative week. None of the patients were overcorrected or developed atypical inflammation. CONCLUSIONS: In this series, patients with Graves' ophthalmology were successfully treated with the use of rectus muscle resections as part of the surgical plan. Careful ocular motility assessment and patient selection is critical if this option is contemplated.
