The objective of this study was to demonstrate that WSI is noninferior to microscopy for primary diagnosis in surgical pathology. A blinded randomized noninferiority study was conducted across the entire range of surgical pathology cases (biopsies and resections, including hematoxylin and eosin, immunohistochemistry, and special stains) from 4 institutions using the original sign-out diagnosis (baseline diagnosis) as the reference standard. Cases were scanned, converted to WSI and randomized. Sixteen pathologists interpreted cases by microscopy or WSI, followed by a wash-out period of ≥4 weeks, after which cases were re...
Prior work has shown that digital images and microscopic slides can be interpreted with comparable diagnostic accuracy. Although accuracy has been well-validated, the interpretative time for digital images has scarcely been studied and concerns about efficiency remain a major barrier to adoption. We investigated the efficiency of digital pathology when compared with glass slide interpretation in the diagnosis of surgical pathology biopsy and resection specimens. Slides were pulled from 510 surgical pathology cases from 5 organ systems (gastrointestinal, gynecologic, liver, bladder, and brain). Original diagnoses were indep...
Conclusion: This is the first report of adverse ocular effects of cervical traction. We postulate that venous and arterial compromise during cervical traction therapy resulted in both ciliochoroidal effusion and a watershed infarct in the outer retina.
Conclusion: Congenital optic disk pit a birth defect in lamina cribrosa is a rare, visually impairing disorder. Spectral domain optical coherence tomography (SD-OCT) scan showed neurosensory detachment, however, lamina cribrosa defects are not delineated with it. SS-OCT a recent advance in scanning technology allows superior resolution of optic disk and confirms the anomaly of lamina cribrosa.
Conclusion: Cystoid macular edema is a rare side effect of the chemotherapeutic drug Paclitaxel. Imaging in Paclitaxel-related CME reveals fluid on ocular coherence tomography scan without leakage on fundus fluorescein angiography, which is in keeping with our findings. There are no recommended treatment guidelines for this condition because of the unclear mechanism of pathology. Treatment strategies have focused on Paclitaxel cessation, which appears to result in spontaneous resolution of CME and improvement in visual acuity. In our patient's case, worsening vision combined with persistent CME and development of retinal...
Conclusion: Adaptive optics scanning laser ophthalmoscopy reveals that dot SDD, like drusen, are dynamic.
Conclusion: Irregularities in the reflectivity of the photoreceptor mosaic are visible on AOSLO even in inactive APMPPE lesions, where the photoreceptor bands on spectral domain optical coherence tomography have recovered. Adaptive optics scanning laser ophthalmoscopy combined with multimodal imaging has the potential to enhance our understanding of photoreceptor involvement in APMPPE.
Conclusion: The results of multimodal imaging clarified the TZ in acute zonal occult outer retinopathy. The TZ was outlined by a distinct high autofluorescence border that correlated with loss of the ellipsoid zone band on spectral-domain optical coherence tomography. However, in fundus areas that seemed healthy on fundus autofluorescence, thinning of the outer retinal layers and thickening of the retinal nerve fiber layer were observed near the TZ. The TZ was also characterized by a decrease in visual sensitivity.
Conclusion: Proper case selection may facilitate successful pharmacologic vitreolysis with ocriplasmin, improve visual outcomes, and minimize potential complications.
Conclusion: Post-milling processing did not affect the internal adaptation of zirconia-reinforced lithium silicate crowns fabricated with a chairside CAD/CAM technique. The new 3D computer technique for the evaluation of fit of restorations may be highly promising and has the opportunity to be applied to clinical studies.
