Anterior segment ischemia following modified Nishida procedure.

Anterior segment ischemia (ASI) can occur following strabismus surgery on multiple muscles. Procedures such as modified Nishida procedure (MNP) have been developed to reduce the risk of ASI. We report the case of a 68-year-old patient presenting with traumatic bilateral abducens nerve palsies who required surgical intervention. We performed MNP with medial rectus recession. The patient presented with reduced vision, corneal edema, anterior chamber reaction, and pupillary dilation 24 hours after surgery. A diagnosis of ASI was made, and immediate reversal of the Nishida procedure was performed. Symptoms improved within 24 hours. In this case, ASI may have been caused by ligation and compression of ciliary arteries due to overstretching of the vertical rectus muscles during transposition.

Muscle Transplantation for Large Angle Horizontal Strabismus.

Large angle sensory strabismus in the form of esotropia and exotropia often calls for bilateral surgery to correct the primary angle deviation. However, considering patients' reluctance to have surgery on the good eye, such large deviations may be managed with true muscle transplantation. The authors present a case series of four patients with large angle esotropia and exotropia who underwent unilateral true muscle transplantation as a single-stage procedure.

Rapid onset of severe ocular injury after exposure to a button battery.

Button batteries are commonly used in many household electronic items and are a potential health hazard, especially in children. We present the case of a 2-year-old girl presented with swelling and redness of her right eye of 3 hours' duration. Examination revealed a button battery that had became lodged in the superior fornix of her right eye. After the intact battery was removed, the patient was found to have suffered an alkali burn to the underlying conjunctiva and sclera. The burn healed with symblepharon formation.

Non-contact ultra-widefield retinal imaging and fundus fluorescein angiography of an infant with incontinentia pigmenti without sedation in an ophthalmic office setting.

When fluorescein angioscopy or angiography is required in an infant, it is usually performed in the operating theater or neonatal unit. We report a case of an infant with incontinentia pigmenti in whom we were able to acquire angiographic information in an office setting by using an ultra-widefield non-contact system with oral fluorescein.

Tissue glue and iatrogenic eyelid gluing in children.

Tissue glues are commonly used in emergency departments to treat straight-edged lacerations and are advocated for use on the face or head. Although application is relatively quick and easy, this can potentially lead to inadvertent eyelid involvement, with potential medicolegal implications. We present 2 cases of such eyelid gluing with tissue glue after it was used on children for closure of supraorbital lacerations.

Surgical treatment of periocular hemangiomas: a single-center experience.

BACKGROUND: At Great Ormond Street Hospital for Children, patients with periocular hemangiomas are assessed in a multidisciplinary team setting using a protocol developed in 1999. As part of this protocol, surgery is indicated for lesions that continue to cause amblyopia despite treatment with systemic or intralesional steroids or both. Surgery is performed by one of the authors (D.D.). This experience is described. METHODS: A retrospective notes review was undertaken of surgically excised periocular hemangiomas. RESULTS: Eighteen consecutive cases (15 girls and three boys) were identified as having surgical treatment over a 5-year period. The mean age at the time of surgery was 22 months (range, 5 months to 3 years). All but one of the patients had amblyopia or a threat to normal visual development. The follow-up ranged from 1 month to 4 years. Three were lower lid lesions and 15 were upper lid lesions. When there was a threat to normal visual development, preoperative imaging by ultrasound, magnetic resonance imaging, or contrast computed tomography was performed. No rebound growth or deterioration in visual development occurred in this group of patients. CONCLUSIONS: There is limited experience in the literature of excisional surgery for the treatment of periocular hemangiomas. The authors present a series of 18 patients who have been treated at Great Ormond Street Hospital for Children after either failed medical therapies or after patient request. With the appropriate indications and surgical principles, periocular hemangiomas in children can be safely and effectively excised.
