Retinal Hemorrhages During Examination for Retinopathy of Prematurity: A Form of Ocular Decompression Retinopathy.

Purpose: Posterior segment hemorrhage occurring during or shortly after examination (PSHE) for retinopathy of prematurity (ROP) is a very rare complication. We present a case of and review the literature on PSHE during ROP examination to better characterize this complication. Methods: A case report is presented, followed by a review of similar cases in the literature. Results: An infant undergoing laser photocoagulation for ROP rapidly developed diffuse intraretinal hemorrhages in his right eye during the laser and after a Valsalva event while he was intubated under general anesthesia. The hemorrhages resolved within 1 week. This presentation was similar to those in previously reported cases. Conclusions: PSHE in ROP usually consists of multiple, diffuse, intraretinal hemorrhages that occur within minutes of ROP examination and resolve within a few weeks without any other ocular findings or sequelae. PSHE seems to represent a form of ocular decompression retinopathy.

Budd-chiari syndrome causing acute liver failure: A multicenter case series.

Budd-Chiari syndrome (BCS) is a rare disease resulting from obstruction of the hepatic venous outflow tract that typically presents with abdominal pain, jaundice, and ascites without frank liver failure. However, BCS may also evolve more rapidly to acute liver failure (ALF). In this study, we describe the clinical features, treatment, and outcomes of ALF due to BCS and compare our results with those in the published literature. Twenty of the 2344 patients enrolled in the Acute Liver Failure Study Group (ALFSG) registry since 1998 presented with a clinical diagnosis of BCS. An additional 19 patients of ALF-BCS in the English language literature were reviewed and compared with the ALFSG cases. Most ALF-BCS patients were white (84%) and female (84%) in their fourth decade. A hypercoagulable state was noted in 63% of patients. BCS was diagnosed by Doppler ultrasonography or abdominal computed tomography in all patients. Liver biopsies (n = 6) all had evidence of severe pericentral necrosis. Treatments used included most commonly anticoagulation (71%), but also transjugular intrahepatic portosystemic shunt (TIPS; 37%) and orthotopic liver transplantation (37%). In-hospital mortality was approximately 60%. In conclusion, BCS is a rare cause of ALF and mandates prompt diagnosis and management for successful outcomes. Once the diagnosis is confirmed, prompt anticoagulation is recommended in conjunction with evaluation for malignancy or thrombophilic disorder. Mortality may have improved in recent years with use of TIPS and/or orthotopic liver transplantation compared with prior published reports. Liver Transplantation 23 135-142 2017 AASLD.

Poor outcomes despite aspirin or statin use in high-risk patients with retinal vein occlusion.

PURPOSE: Since atherosclerosis contributes to the pathophysiology of retinal vein occlusion (RVO), we aimed to assess the effects of aspirin and statins on the visual outcomes of RVO in high-risk patients, whom we define to have hypertension and open-angle glaucoma prior to RVO. METHODS: We conducted a retrospective case-control study of adults diagnosed with RVO between 2006 and 2014. To evaluate for a preventive effect of these medications, we compared the prevalence of aspirin or statin use (either separately or concomitantly) among high-risk patients who developed RVO and among those who did not during at least 2 years of follow-up. To evaluate for a therapeutic effect, we then compared the final follow-up visual acuity (VA) of high-risk RVO patients who had and who had not been taking a statin prior to the RVO. RESULTS: We analyzed 43 eyes [23 central RVOs (CRVOs), 16 branch RVOs (BRVOs), and 4 hemi-RVOs (HRVOs)] from 42 high-risk patients, along with 129 high-risk controls. There was no significant difference (p = 0.47) in aspirin exposure between the control (60%) and RVO (67%) groups, and the increased statin exposure among controls (72% vs. 53% for the cases; p = 0.03) paralleled their higher prevalence of hyperlipidemia. The non-statin and statin RVO groups each had a mean VA of 20/800 at a mean 30 and 43 months of follow-up, respectively. CONCLUSIONS: No preventive benefit of aspirin or statins, and no therapeutic benefit of statins, was found for RVO in high-risk patients. High-risk RVO patients suffer substantially worse outcomes than those reported in other studies not limited to such patients.
