Visual outcomes in children with bilateral retinoblastoma.

BACKGROUND: Retinoblastoma is the most common primary intraocular tumor of childhood. Although studies have explored trends in retinoblastoma management and prognosis, few have addressed visual outcome. METHODS: A retrospective chart review was performed on children in whom bilateral retinoblastoma was diagnosed at New York Hospital-Cornell Medical College. A total of 74 children were included in the study. All children underwent radiation to the eyes that were studied. Fundus drawings done at the time of diagnosis were evaluated to determine the location of tumors on presentation and the Reese-Ellsworth classification. Visual outcome was classified into 3 groups: group 1 represented visual acuity of 20/20 to 20/40; group 2, 20/50 to 20/400, and group 3, <20/400. RESULTS: A total of 74 children were studied. Forty-six (62%) underwent enucleation of 1 eye. The visual acuity of the remaining 102 eyes was divided into groups 1, 2, and 3. Fifty-eight percent of these eyes were in group 1, 31% in group 2, and 9% in group 3. Two percent underwent subsequent enucleation after treatment. The tumors were analyzed on the basis of Reese-Ellsworth classification, location, size, and distance from the macula. Excluding Reese-Ellsworth group VB, there was no correlation between Reese-Ellsworth classification and final visual outcome. Tumors involving the macula were in 7 (78%) of 9 eyes with poor visual outcome (group 3), and 16 (33%) of 48 eyes with excellent vision (group 1) had macular tumors. Paradoxically, 2 (22%) of 9 eyes in group 3 did not have tumors involving the macula. CONCLUSIONS: Children with retinoblastoma now have an excellent prognosis for life. Although correlated with tumor location, visual outcome is not always easily predicted on the basis of the initial presentation. Final acuity is excellent in most cases but may be influenced by multiple factors that must be considered when caring for these children and families.

Results of Müllerotomy and levator aponeurosis transposition for the correction of upper eyelid retraction in Graves disease.

BACKGROUND: Upper eyelid retraction in Graves disease may cause functional morbidity and aesthetic deformity. Surgery to correct thyroid-related upper eyelid retraction may result in temporal undercorrection with failure to eliminate lateral eyelid retraction, leading in turn to a poor eyelid contour postoperatively. METHODS: In 1984, one of the authors developed a new procedure for correcting moderate to severe upper eyelid retraction associated with Graves disease. The surgical technique consists of a Müllerotomy and recession of the levator aponeurosis combined with medial transposition of the lateral horn of the levator aponeurosis. The procedure was performed on 37 patients (72 eyelids). Müller's muscle was used as the spacer to set the eyelid height. Transposition of the levator aponeurosis allowed adjustment of eyelid contour. RESULTS: Thirty patients (58 eyelids) had excellent results, six (13 eyelids) had good results, and one (1 eyelid) had a poor result. No patient required re-operation for asymmetry, unacceptable contour, or malposition. Only one eyelid had significant overcorrection, and only one eyelid had significant undercorrection, requiring further surgery. The most frequent unwanted effects were high eyelid crease (24 eyelids) and residual temporal flare (6 eyelids); however, most of these were seen early in the series before the lateral levator transposition modification was added. CONCLUSION: This procedure allows successful and simultaneous correction of both eyelid position and contour in patients with moderate to severe thyroid-related upper eyelid retraction.

Chondroblastoma of the temporal bone. Case report and literature review.

Chondroblastoma is a rare tumor of bone that represents approximately 1% of all primary bone tumors. In the temporal bone, only 33 have been reported. We present a case of chondroblastoma of the temporal bone, followed by a literature review and analysis of reported cases. We conclude that the best chance for a prolonged disease-free interval is total excision using a combined otolaryngologic and neurosurgical approach.
