Conditional deletion of Des1 in the mouse retina does not impair the visual cycle in cones.

FASEB J 2019 Jan 15:fj201802493R. Epub 2019 Jan 15.

Department of Pharmacology, Case Western Reserve University School of Medicine, Cleveland, Ohio, USA.

Cone photoreceptors are essential for vision under moderate to high illuminance and allow color discrimination. Their fast dark adaptation rate and resistance to saturation are believed to depend in part on an intraretinal visual cycle that supplies 11- cis-retinaldehyde to cone opsins. Candidate enzymes of this pathway have been reported, but their physiologic contribution to cone photoresponses remains unknown. Read More

The mediodorsal pulvinar coordinates the macaque fronto-parietal network during rhythmic spatial attention.

Nat Commun 2019 Jan 15;10(1):215. Epub 2019 Jan 15.

Princeton Neuroscience Institute, Princeton University, Princeton, NJ, 08544, USA.

Spatial attention is discontinuous, sampling behaviorally relevant locations in theta-rhythmic cycles (3-6 Hz). Underlying this rhythmic sampling are intrinsic theta oscillations in frontal and parietal cortices that provide a clocking mechanism for two alternating attentional states that are associated with either engagement at the presently attended location (and enhanced perceptual sensitivity) or disengagement (and diminished perceptual sensitivity). It has remained unclear, however, how these theta-dependent states are coordinated across the large-scale network that directs spatial attention. Read More

Eye-Sparing Treatment for Diffuse Invasive Conjunctival Melanoma.

Ocul Oncol Pathol 2018 Jun 1;4(4):261-266. Epub 2018 Feb 1.

Department of Ophthalmology, University of Cincinnati College of Medicine, Cincinnati, Ohio, USA.

The management of patients with diffuse invasive conjunctival melanoma focuses on local tumor control and screening for metastasis. Despite the lack of consensus on the benefit of sentinel lymph node biopsy for these neoplasms, the information obtained by histopathology is useful for tumor staging and treatment planning. Due to the lack of evidence of survival improvement, orbital exenteration is being performed with diminishing frequency. Read More

Primary Cutaneous Angiosarcoma of the Eyelid: A Diagnostic and Therapeutic Challenge.

Ocul Oncol Pathol 2018 Jun 12;4(4):230-235. Epub 2018 Jan 12.

Department of Ophthalmic Pathology, Thomas Jefferson University, Philadelphia, PA, USA.

Primary cutaneous angiosarcoma is a rare vasoformative malignant neoplasm that can present a diagnostic and therapeutic challenge. We describe a 76-year-old Caucasian man with right upper eyelid swelling and nodularity, initially suspected clinically to represent either ocular adnexal lymphoma or basal cell carcinoma. Incisional biopsy and wide resection of the mass with frozen section control of margins were interpreted as compatible with hobnail (Dabska-retiform) hemangioendothelioma. Read More

Optical Coherence Tomography: Clinicopathologic Correlations - The 2016 Gordon K. Klintworth Lecture.

Authors:
Ralph C Eagle

Ocul Oncol Pathol 2018 Jun 16;4(4):203-212. Epub 2017 Dec 16.

Department of Pathology, Wills Eye Hospital, Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, PA, USA.

Background/aims: Spectral domain optical coherence tomography (SD-OCT) has become a mainstay of ophthalmic practice that has revolutionized the assessment and treatment of a variety of ocular disorders. Studies that directly correlate SD-OCT and histopathology are necessary to demonstrate the actual nature of the retinal pathology responsible for the images that resemble histologic sections, but are generated by mathematical algorithms.

Methods: Careful correlative light microscopy was performed on a small number of eyes undergoing enucleation for intraocular tumors that had pertinent findings imaged by SD-OCT. Read More
