Dog bites result in a diverse range of injuries and complications in the periocular region, particularly in school aged children. It is therefore incumbent on the oculoplastic surgeon to be well versed in both acute and long-term management. The intent of this review is to provide a systematic evaluation of the epidemiology, principles of dog bite wound care, and specific considerations related to common patterns of ophthalmic injury. Review of clinical literature from 1976 to 2014. The majority of periocular injuries result from seemingly benign interactions between young children and familiar dogs. Aggressive saline lavage combined with selective debridement of devitalized tissue is essential. High-risk wounds and vulnerable patient groups may benefit from preventive antibiotic coverage as well as appropriate rabies and tetanus prophylaxis. While the nuances of surgical repair are variable given the heterogeneity of presentation, systematic examination and an algorithm-driven approach underlie the optimal management of these complex injuries.

We report a case of iatrogenic creation of an excessive anterior-to-posterior gradient in the setting of an open anterior capsule during capsulorhexis. This complication shows the inverse mechanism of that observed in the Argentinean flag sign. An excessive anterior-to-posterior gradient from an exuberant ophthalmic viscosurgical device fill of the anterior chamber caused radialization of the anterior capsule during creation of a continuous curvilinear capsulorhexis in a nonintumescent lens. We describe this complication as the reverse Argentinean flag sign.

PURPOSE: To describe a case of posterior scleritis with serous choroidal detachment that occurred as an acute complication of herpes zoster ophthalmicus (HZO). METHODS: Retrospective case report. RESULTS: A 75-year-old female presented with 3 days of painful, decreased vision in her left eye 1 week after being diagnosed with HZO. She had unilateral crusted vesicular lesions in the V1 dermatomal distribution and corneal pseudodendrites. Funduscopic examination demonstrated a large choroidal detachment in her left eye. B-scan ultrasonography revealed unilaterally thickened sclera consistent with posterior scleritis. She was treated with oral prednisone and a 2-week course of intravenous acyclovir. Two weeks after the initiation of treatment, her vision had improved and she demonstrated complete resolution of her pseudodendrites, posterior scleritis, and choroidal detachment. CONCLUSIONS: Prompt recognition and treatment of this unique combination of clinical manifestations of HZO resulted in significant improvement in vision and resolution of the scleritis and choroidal detachment.

PURPOSE OF REVIEW/OBJECTIVE:This review will seek to answer if advances in ophthalmic imaging and evolution of treatment modalities have shed further light on the epidemiology, pathophysiology, diagnosis, and acute management of acute CRAO. RECENT FINDINGS/RESULTS:Imaging characteristics of acute CRAO have been further characterized with the use of fluorescein angiography, optical coherence tomography (OCT), OCT-angiography, and indocyanine-green angiography. Layer segmentation of OCT imaging has found inner retinal layer hyper-reflectivity to be a common finding in acute CRAO. Non-invasive therapies, fibrinolytic delivery, and surgical interventions for acute CRAO have been further evaluated as potential management tools. SUMMARY/CONCLUSIONS:A large body of literature reports very inconsistent treatment success with a wide variety of modalities. Currently, there is no clear evidence supporting the use of fibrinolytics in acute CRAO. Large, multicenter, randomized control trials are necessary to elucidate the role of the various acute treatment options in the management of CRAO.
