To report the clinical and refractive outcomes of a modified Yamane technique for scleral fixation of the CT Lucia 602 lens.
Retrospective case series.
One hundred twenty-one eyeswith dislocated posterior chamber lens implants, surgical aphakia, subluxed crystalline lenses, capsular tear, anterior chamber, or iris sutured posterior chamber lens intolerance were included.
Secondary implantation of the Zeiss CT Lucia 602 lens was performed by a single surgeon using a modified Yamane technique employing a single needle, rather than the double-needle approach. One hundred twelve eyes underwent simultaneous 3 port pars plana vitrectomy and 9 eyes had previously undergone posterior vitrectomy surgery. Exclusion criteria were age <18, simultaneous glaucoma or corneal procedures, staged corneal transplantation, and follow-up <30 days.
A paired
-test was used to compare pre- and post-operative corrected distance visual acuity (CDVA), the mean predictive error, and the mean absolute predictive error btions in this heterogeneous group of eyes with significant comorbidities.
Scleral fixation of the CT Lucia 602 lens using a single-needle modification of the Yamane technique resulted in very good visual acuity, predictable postoperative refractive errors, but some vision-limiting complications in this heterogeneous group of eyes with significant comorbidities.The incidence of herpes simplex keratitis (HSK) in patients following corneal refractive surgery is higher than in the general population, and several case reports of ocular morbidity in HSK infection following corneal refractive surgery have been published. selleck compound HSK is listed by the American Academy of Ophthalmology as a relative contraindication to corneal refractive surgery, although specifics have not been further elucidated. This review summarizes the current literature regarding reactivation of HSK following corneal refractive surgery and provides a guideline for considering corneal refractive surgery in a patient with a previous history of HSK. Based on the current literature, we recommend that corneal refractive surgery is appropriate for patients with a history of HSK without multiple recurrences who have had no evidence of disease for at least one year. In addition to a thorough history and physical examination, we also recommend these patients begin 400 mg twice daily of oral acyclovir or valacyclovir 500 mg once daily for two weeks prior to surgery and continue this regimen for at least two weeks postoperatively or while on topical steroids.
The purpose of this study was to evaluate the ability to screen for glaucoma using a Food Drug Administration (FDA) Class II diagnostic digital fundus photography system used for diabetic retinopathy screening (DRS).
All research participants underwent a comprehensive eye examination as well as non-mydriatic 45°single photograph retinal imaging centered on the macula. Optic nerve images within the 45° non-mydriatic and non-stereo DRS image were evaluated by two methods 1) grading by three glaucoma specialists, and 2) a computer-aided automated segmentation system to determine the vertical cup-to-disc ratio (VCDR). Using VCDR from clinical assessment as gold standard, VCDR results from two methods were compared to that from clinical assessment. Inter-grader agreement was assessed by computing intraclass correlation coefficient (ICC). In addition, sensitivity and specificity were calculated.
Among 245 fundus photos, 166 images met quality specifications for analysis. Fifty images were not processed by theic nerve assessment for glaucoma from these 45° non-mydriatic and non-stereo DRS images is not yet suitable for tele-glaucoma screening.
This study evaluates the effect of anti-vascular endothelial growth factor (anti-VEGF) therapy on microaneurysm changes and foveal avascular zone (FAZ) using optical coherence tomography angiography (OCTA) in patients with diabetic macular edema (DME).
Prospective observational study.
This study involved patients with DME undergoing anti-VEGF treatment (aflibercept, ranibizumab, and bevacizumab). Macula OCTA images were obtained before (visit 0) and 1 month after (visit 1) anti-VEGF injection. Microaneurysm counts were performed, and the FAZ was evaluated in the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The differences in microaneurysms, FAZ, and clinical correlations were analyzed.
A total of 152 eyes were analyzed. The patients' mean age was 59 years. Bevacizumab was used in 69.7%, ranibizumab in 15.1%, and aflibercept in 15.1%. There was a significant reduction in the FAZ in the SCP and DCP between visits 0 and 1. All anti-VEGF medications reduced the number of microaneurysms (p<0.01). link2 After treatment, changes in the FAZ in SCP and DCP corresponded with changes in visual acuity (p<0.01).
Microaneurysms as detected by OCTA might serve as a biomarker for a clinical response to anti-VEGF treatment in the short term. The FAZ might also predict visual acuity improvement after anti-VEGF injection.

Thai Clinical Trials Registry (TCTR20161010005).High-risk "protected" percutaneous coronary intervention (PCI) using mechanical circulatory support (MCS) devices, particularly the Impella axial pump, has emerged as a viable treatment option for high-risk patients with satisfactory clinical outcomes. High-risk and complex interventions have mostly remained within the domain of surgical centers. We report on an early "protected" PCI experience using MCS with the Impella flow pump at a high-volume PCI hospital without on-site surgery. A total of 5 patients underwent elective "protected" PCI utilizing MCS with Impella at our institution. The mean left ventricular ejection fraction was 28 ± 10% and all patients had triple vessel coronary artery disease with the majority having a high SYNTAX score. Device implantation and procedural success were achieved in all cases with no intraprocedural or access site complications. All patients were alive at 30 days and clinically well. The Impella unloads the ventricle, improves forward cardiac output and lowers myocardial oxygen demand, thereby improving mean arterial pressure and coronary perfusion. Device insertion is relatively quick and the "learning curve" is short, centering mainly around managing large bore access. Our limited experience suggests that not only is high-risk PCI with Impella support feasible in a non-surgical center, but that it may be crucial to enable success.
The relationship between exercise and cerebral oxygenation has gained increasing attention. However, few studies have investigated the correlation between exercise and cerebral oxygenation in patients with cardiopulmonary diseases.
To investigate the correlation between exercise and cerebral oxygenation in patients with cardiopulmonary diseases.
Thirty eligible patients with cardiopulmonary diseases underwent incremental cardiopulmonary exercising test (CPET) and near-infrared spectroscopy with both right and left sensors placed at the mid forehead to detect oxygen saturation of cerebral tissue (STO2). Parameters of cerebral oxygenation and exercise intensity were collected and analyzed.
The average age of the patients was 51.17 ± 10.21 years and included 23 males and 7 females. The average maximal STO2 of the left and right brain during CPET were 51.850 ± 1.57% and 51.755 ± 1.90%, respectively. link3 Meanwhile, mean oxygen consumption (VO2) while reaching maximal STO2 was 4.42 ± 1.05 metabolic equivalents (METs) over the left brain and 4.34 ± 1.17 METs over the right brain. The exercise intensity upon reaching maximal STO2 was 84.91 ± 11.70% over the left brain and 83.16 ± 14.64% over the right brain. Peak VO2 was significantly correlated to VO2 upon reaching maximal STO2 over the left and right brain (R = 0.805, p < 0.001 and R = 0.739, p < 0.001, respectively). Age was significantly negatively correlated to VO2 upon maximal STO2 over the left and right brain (R = -0.378, p = 0.039 and R = -0.513, p = 0.004, respectively).
Cerebral oxygenation increases with higher exercise intensity, and it reaches a maximal STO2 between respiratory compensation point and peak exercise. The higher the peak VO2, the better the VO2 upon reaching maximal STO2.

We developed a new fully bioresorbable vascular scaffold covered with biodegradable poly-L-lactic acid film (Firesorb-C) for coronary artery perforation. Our vitro tests have demonstrated that Firesorb-C was technically feasible but its biosafety and efficacy warranted further validation in vivo.
The aim of this study was to evaluate the biosafety and efficacy of Firesorb-C in rabbits.
Firesorb-C was deployed at the zone from the abdominal aorta to the right iliac artery in five rabbits. Angiography was conducted for evaluation of the immediate efficacy and 6-month biosafety and biodegradability of the Firesorb-C. Meanwhile, optical coherence tomography (OCT), histological light microscopy (HLM) and scan electron microscopy (SEM) were performed to evaluate the biosafety.
All Firesorb-C applications were successfully implanted without procedure-related complications. In all treated rabbits, angiography showed that the Firesorb-C had completely sealed the opening of the left iliac artery without blood flow in its branches but with full patency of the right iliac artery immediately post-procedurally, while the covered membrane of Firesorb-C had been degraded and blood flow was restored in the left iliac artery and its branches at 6 months. OCT also found that the occluded left iliac artery had been reopened and the stented segment was almost fully endothelialized without in-stent restenosis at 6 months, meanwhile HLM and SEM confirmed comparable results.
Firesorb-C is associated with excellent efficacy, biosafety and biodegradability in rabbits. It shows promise as a replacement for conventional covered stents for treatment of coronary artery perforation or for use in other clinical situations.
