Asymptomatic Hepatic Sequestration with Extreme Hyperbilirubinemia in an Adult Homozygous Sickle Cell Patient.

It has been estimated that there are greater than 100,000 individuals in the US with sickle cell disease. Hepatic sequestration is a known sequelae of sickle cell disease that rarely leads to extreme hyperbilirubinemia (total serum bilirubin greater than 20 mg/dl). Our 26-year-old male patient, though compliant with regular transfusion exchanges, presented with hepatic sequestration, with minimal symptoms and hyperbilirubinemia up to approximately 40 mg/dl. The severity of asymptomatic hepatic sequestration seen in our patient has never been reported in the literature. This mandates a low threshold to screen for sickle cell complications and promptly treating these patients admitted to the hospital with exchange transfusions.

Shortest Distance From Fovea to Subfoveal Hemorrhage Border Is Important in Patients With Neovascular Age-related Macular Degeneration.

PURPOSE: To identify factors influencing visual outcome in patients with neovascular age-related macular degeneration (NVAMD) and subfoveal hemorrhage (SFH) treated with anti-vascular endothelial growth factor (VEGF) agents. DESIGN: Retrospective case series. METHODS: Anti-VEGF-treated eyes with SFH > 1 disc area (DA) were identified (n = 16) and changes in visual acuity (VA) and central subfield thickness (CST) from baseline to last follow-up, along with SFH area, thickness, minimum distance from fovea to SFH border, and time to resolution, were determined. RESULTS: At baseline, mean (± standard error of the mean) size and thickness of SFH were 14.9 ± 2.8 DA and 386.6 ± 46.9 µm, and mean Snellen VA and CST were 20/250 and 591.7 ± 57.0 µm. Median follow-up was 47.6 months. While more than 50% of patients had VA ≤ 20/200 at baseline and all time points through week 48, the percentage of patients with VA ≥ 20/50 increased to 30%-40% at months 6 and 12 and remained stable through month 48. Spearman rank correlation demonstrated 2 independent variables that correlated with good visual outcome, smaller area of SFH at baseline (r = -0.630; P = .009), and high frequency of anti-VEGF injections (r = 0.646; P = .007). In exceptional patients with good visual outcome despite large baseline SFH, shortest distance between the fovea and hemorrhage border significantly correlated with baseline VA (r = -0.503, P = .047) and final VA (r = -0.575, P = .02). CONCLUSIONS: Patients with NVAMD and thick SFH, but short distance between fovea and uninvolved retina, can have good visual outcomes when given frequent anti-VEGF injections.
