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.

PURPOSE: To determine provider compliance with hydroxychloroquine screening following the revised recommendations published in 2011 by the American Academy of Ophthalmology. DESIGN: Evaluation of adherence to a screening protocol. METHODS: Subjects were identified with hydroxychloroquine as a medication by electronic query at a large multispecialty ophthalmic practice. Patients were excluded if patients: (1) were screened by an outside physician; (2) lacked recorded height, weight, start date, or dosing; or (3) took hydroxychloroquine for malaria prophylaxis. Screening tests were stratified by ophthalmic subspecialty. Guidelines define proper screening as 1 subjective test-Humphrey visual field (HVF), and 1 objective test-spectral-domain optical coherence tomography (SD OCT), fundus autofluorescence (FAF), or multifocal electroretinography (mfERG). Adherence to guidelines was determined by categorizing practices as: (1) "appropriate"-consistent with guidelines; (2) "underscreened"-insufficient testing; or (3) "inappropriate"-no testing. RESULTS: The study comprised 756 patients with a mean age of 56 years undergoing 1294 screening visits. Twenty-one patients received initial screenings outside the institution. Most common screening tests employed included SD OCT (56.6%), 10-2 HVF (55.0%), and Amsler grid (40.0%). Of the 735 initial screenings, 341 (46.4%) were appropriately screened, 204 (27.8%) underscreened, and 190 (25.9%) inappropriately screened. Of those who presented solely for screening (560), 307 (54.8%) were appropriately screened, 144 (25.7%) underscreened, and 109 (19.5%) inappropriately screened. CONCLUSIONS: Of patients presenting for hydroxychloroquine screening, 54.8% of patients received appropriate evaluation, indicating lack of adherence to guidelines. Overall, SD OCT and 10-2 HVF were the preferred screening modalities, with FAF and mfERG less frequently ordered.
