Purpose/UNASSIGNED:To determine if inner retinal layer reflectivity in eyes with acute central retinal vein occlusion (CRVO) correlates with visual acuity at 12 months. Methods/UNASSIGNED:Macular optical coherence tomography (OCT) scans were obtained from 22 eyes of 22 patients with acute CRVO. Optical intensity ratios (OIRs), defined as the mean OCT reflectivity of the inner retinal layers normalized to the mean reflectivity of the RPE, were measured from the presenting and 1-month OCT image by both manual measurements of grayscale B-scans and custom algorithmic measurement of raw OCT volume data. OIRs were assessed for association with final visual outcome. Cohort subgroup division for analysis was determined statistically. Results/UNASSIGNED:Eyes with poorer final visual acuity (≥20/70) at 1 year were more likely to have a higher ganglion cell layer OIR than eyes with better final visual acuity (<20/70) at 1 month (manually: 0.591 to 0.735, P = 0.006, algorithmically: 0.663 to 0.799, P = 0.014). At 1 month, eyes with a poorer final visual acuity demonstrated a higher variance of OIR measurements (algorithmically: 0.087 vs. 0.160, P = 0.002) per scan than eyes with better final visual acuity. Conclusions/UNASSIGNED:In acute CRVO, ganglion cell layer changes at 1 month, including increased reflectivity and increased heterogeneity of reflectivity signal as expressed as OIR and OIR variance, were associated with a poorer visual prognosis at 1 year. Technique calibration with larger sample sizes and automated integration into OCT platforms will be necessary to determine if OIR can be a clinically useful prognostic tool.

PURPOSE/OBJECTIVE:To report a case of bilateral toxic corneal and conjunctival epitheliopathy secondary to administration of filter paper impregnated with lysergic acid diethylamide (LSD) in the inferior conjunctival fornices. METHODS:This is a single case report of an 18-year-old man who presented to the emergency department with acute, bilateral eye pain and redness of 24 hours. The patient admitted to placing folded strips of blotting paper impregnated with LSD into the inferior fornices of his eyes the previous night. RESULTS:The patient was found to have localized bilateral corneal and conjunctival abrasions with underlying subconjunctival hemorrhage. Conjunctival abrasion was "kissing," involving the bulbar and palpebral conjunctiva, corresponding to the presumed location of the filter paper. There was no corneal stromal opacification. He was lost to follow up within 1 week of initial presentation but stated that his symptoms improved. CONCLUSIONS:To the best of our knowledge, this is the first reported case of bilateral hemorrhagic conjunctival abrasion and corneal abrasion secondary to LSD. "Kissing" conjunctival lesions, which have been previously reported with heroin use, should raise suspicion for drug abuse.

PURPOSE/OBJECTIVE:To describe a case of endogenous endophthalmitis from Streptococcus dysgalactiae subspecies equisimilis in the setting of an aortic valve abscess Methods: Retrospective case report. RESULTS:A 72-year-old white male presented with fevers, encephalopathy, and decreased vision in his left eye. His visual acuity was 20/20 in his right eye and finger counting in the left eye. Workup revealed an aortic valve abscess. Examination of his left eye revealed dense anterior chamber fibrin and no view of the retina. B-scan ultrasonography revealed loculated hyperechoic areas consistent with vitreous inflammation. A vitreous tap and injections with vancomycin and ceftazidime were performed. Visual acuity worsened to no-light perception 5 days later. Vitreous and blood cultures grew Streptococcus dysgalactiae subspecies equisimilis. He received another intravitreal injection of vancomycin with no improvement. CONCLUSIONS:Streptococcus dysgalactiae subspecies equisimilis is an emerging pathogen and may cause severe intraocular infections with a poor visual outcome.

An 8-year-old girl with a history of type 1 diabetes was referred for an evaluation of pigment changes in the right macula. Curvilinear hypopigmented streaks were noted in the fovea, with corresponding disruption of the photoreceptor layer on spectral domain optical coherence tomography. On further questioning, a history of laser pointer play 2 years prior was elicited, with acknowledgement of direct laser pointing in the child's eye. The family was advised to remove any commercial laser devices from the home, and observation of the pathology was recommended.

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.
