Severe neutropenia presenting with Candida albicans eyelid abscess in a 1-year-old child.

A previously healthy 1-year-old boy presented with a right lower eyelid abscess. Oral and topical antibiotics were initiated, and the lesion was drained and explored. Despite medical and surgical treatment, the abscess failed to resolve completely and formed again 1 month later. A second incision and drainage procedure was performed, and Candida albicans grew in cultures. Additional workup revealed severe neutropenia with an absolute neutrophil count of 0.18 k/µl (1.19-7.21 k/µl). The abscess resolved after 2 weeks of oral fluconazole. C. albicans eyelid abscess may be the presenting sign of systemic immunodeficiency.

Iris atrophy following intracameral dexamethasone injection: a report of two pediatric cases.

We report 2 pediatric cases of iris atrophy that developed roughly 1 month after intracameral injection of dexamethasone suspension 9% following unilateral goniotomy and cataract extraction.

Congenital abnormalities of the optic nerve: from gene mutation to clinical expression.

Optic nerve malformations are common causes of congenital blindness and are recognized with increasing prevalence. The importance of identifying these malformations lies not only in determining the cause and level of visual impairment, but also in looking for associated treatable or life threatening systemic conditions. A number of genetic mutations have been identified in the development of optic disc anomalies, such as ones in PAX2 or PAX6. Recent advances in genetic testing like array comparative genomic hybridization allow the detection of microdeletions that were previously difficult or impossible to identify.

Bilateral conjunctival follicular lymphoma in a child.

Follicular lymphoma is exceedingly rare in children. We present the case of a 10-year-old patient with a conjunctival lesion on the left eye who later developed a similar lesion on the right eye. Excisional biopsy of the left eye lesion revealed follicular lymphoma. The patient was treated with systemic rituximab. To our knowledge, only 4 other cases of pediatric conjunctival follicular lymphoma have been reported, all of which were isolated lesions that were treated with excisional biopsy alone.

The effects of surgical factors on postoperative astigmatism in patients enrolled in the Infant Aphakia Treatment Study (IATS).

PURPOSE: To evaluate the effect of surgical factors on postoperative astigmatism in infants undergoing cataract extraction with or without intraocular lens (IOL) implantation. METHODS: The Infant Aphakia Treatment Study is a multicenter clinical trial in which 114 infants with unilateral congenital cataracts were randomized to undergo cataract extraction with IOL placement or contact lens aphakic correction. Surgical videos were reviewed with regard to incision type and location, whether the incision was extended, the number of sutures placed, and technique of closure. Corneal astigmatism was measured using a handheld keratometer prior to surgery and at 1 year of age. RESULTS: Corneal astigmatism decreased from a mean of 1.92 D at baseline to 1.62 D at age 1 year in the contact lens group but remained almost unchanged from 2.00 D to 2.09 D in the IOL group (P = 0.023). There was no statistical difference between the amount of corneal astigmatism with regard to incision type (P = 0.214) and no increase in astigmatism with extension of the incision to facilitate IOL placement (P = 0.849) at 1 year. The number of sutures and technique of closure did not influence the amount of astigmatism at 1 year. CONCLUSIONS: At the age of 1 year following cataract extraction in infants, contact lens correction and the lack of IOL placement are associated with a significant decrease in postoperative corneal astigmatism compared to IOL placement. No other surgical factors considered in this study had a statistically significant effect on corneal astigmatism.
