5; P=0.003), but not in either localized (HR 0.8; P=0.2) or in regional ADKUB (HR 1.0; P=0.9). In metastatic ADKUB, the benefit of chemotherapy on CSM persisted after 11 propensity score matching (HR 0.6; P=0.002) and after inverse probability of treatment weighting (HR 0.4; P less then 0.001). Conclusions Chemotherapy improves survival in metastatic ADKUB. However, only one out of 2 such patients benefit from chemotherapy. In consequence, greater emphasis on chemotherapy use may be warranted in these patients. Conversely, no benefit was identified in localized or regional ADKUB.An 8-year-old boy with a history of refractory acute lymphoblastic leukemia presented with left-sided periorbital erythema and painless enlargement of the lacrimal sac. MRI revealed a soft tissue mass on the floor of the left orbit, extending into the nasolacrimal sac and duct. Lacrimal sac biopsy was consistent with B-lymphoblastic leukemia. The patient was treated with chemotherapy and radiation with satisfactory remission of local disease. However, similar symptoms emerged shortly after on the contralateral side, and repeat MRI was concerning for new leukemic infiltration of the right lacrimal sac. Bone marrow biopsy revealed concurrent medullary relapse. DNA Damage inhibitor Systemic chemotherapy was adjusted and radiation therapy of the right orbit was initiated. This is the first reported pediatric case of bilateral leukemic involvement of the lacrimal sac.Purpose To determine the efficacy of a frontalis muscle flap eyelid reanimation technique for correction of severe congenital ptosis and associated amblyopia in infants. Methods The authors performed a retrospective chart review of patients 12 months of age or younger with unilateral or bilateral congenital ptosis and associated amblyopia or deemed at high risk for amblyopia due to visual deprivation. Following ptosis repair via a frontalis muscle flap technique, primary outcomes of postoperative eyelid position and amblyopia reversal were assessed. Results Seventeen eyes of 12 participants were included for study. Seven of these patients had simple congenital ptosis, and the remainder had ptosis as part of a syndrome. Nine were diagnosed with amblyopia preoperatively, and the remaining 3 were too young for acuity testing but had occlusion of the visual axis by the ptotic eyelid in primary gaze. Postoperatively, the mean margin-to-reflex distance 1 was 2.4 mm (range 0.0-4.0), and 9 patients (75%) demonstrated no evidence of amblyopia. Only 2 patients had eyelid asymmetry greater than 2 mm, which in both cases was due to lack of frontalis activation by the patient secondary to ongoing visual impairment. The most common complication was lagophthalmos in 6 eyes (35.3%), with no significant associated surface keratopathy. Conclusions The frontalis muscle flap technique may offer a new and effective approach to treating infants with severe congenital ptosis causing poor eyelid excursion and associated amblyopia while avoiding use of an implant.Purpose It is generally believed that large eyelid defects must be repaired using a vascularized flap for 1 lamella, while the other can be a free graft. Recent studies indicate that the pedicle of a tarsoconjunctival flap does not contribute to blood perfusion. The purpose of this study was to explore whether large eyelid defects can be repaired using a free bilamellar eyelid autograft alone. Methods Ten large upper and lower eyelid defects resulting from tumor excision were reconstructed using bilamellar grafts harvested from the contralateral or opposing eyelid. Revascularization of the flap was monitored during healing using laser speckle contrast imaging, and the surgical outcome was assessed. Results The functional and cosmetic results were excellent. All grafts survived and there was no tissue necrosis. Only 1 patient underwent revision after 4 days as the sutures came loose. Two patients developed minimal ectropion but needed no reoperation. All patients were satisfied with the surgical results. Perfusion monitoring showed that the grafts were gradually revascularized, exhibiting 50% perfusion after 4 weeks and 90% perfusion after 8 weeks. Conclusions A free bilamellar eyelid graft appears to be an excellent alternative to the tarsoconjunctival flap procedure in the reconstruction of both upper and lower eyelid defects, especially in patients who cannot tolerate visual axis occlusion or the 2-stage procedure of the conventional staged flap procedure.Purpose To assess efficacy of intravenous (IV) ketorolac for postoperative pain control after external dacryocystorhinostomy. Method Fifty-five patients from January to April 2019 were randomized, to a double-blind prospective interventional study. Intervention arm received IV ketorolac (60 mg/2 ml) immediately post-op, control received IV saline bolus. Pain assessment was done with numerical rating scale pre- and postinjection (day 0) and on day 1. Requirement for analgesics and antiemetics was recorded. Results Total 55 patients (11 men and 44 women) with mean age 49.93 ± 16.29 years were included in the study. Twenty-four (43.6%) patients received IV ketorolac and 31 (56.4%) received placebo. Mann-Whitney U test showed mean rank score for pain scale was significantly lower in intervention arm versus control arm, assessed postinjection (16.69 vs. 36.76 respectively, p = .000) and at day 1 (21.08 vs. 33.35 respectively, p = .003). Conclusion IV ketorolac significantly lowers self-reported pain score following external dacryocystorhinostomy with reduced requirement of analgesic and antiemetic medications.Purpose Injury to the eye and/or orbital and adnexal structures associated with antiquated muzzle-loading firearms has not, to our knowledge, been characterized with the exception of a single case report. Methods A retrospective chart review of 7 patients treated at Vanderbilt University Medical Center from 2003 to 2017 who sustained traumatic injuries to the ocular and/or orbital structures secondary to the discharge of muzzle-loading firearms. The study was approved by the Vanderbilt Institutional Review Board. Results In 6/7 cases, injuries occurred secondary to the muzzle-loading firearm exploding due to dysfunction or misuse. Foreign material deriving from the firearm was retained in 3/7 patients. Initial examination of the orbit and adnexa revealed 5/7 individuals sustaining orbital fractures and 6/7 with facial lacerations (including 2 with eyelid lacerations); none had evidence of a lacrimal duct injury. Three patients suffered globe injuries (1 closed-globe and 2 open-globe). Visual acuity at last follow-up was ≥20/20 in 12/14 eyes examined.
