Neuroretinitis as a Complication of Cat Scratch Disease.

In this case report, a patient with neuroretinitis from a  infection is described, and insights into methods to distinguish this type of case from more common etiologies of optic nerve edema are presented. A 21-year-old female with a history of right monocular vision loss due to amblyopia presented to the emergency department (ED) with occipital headache, fever, dizziness, nasal congestion, and painless blurry vision in the left eye for one day. A lumbar puncture found a slightly high opening pressure but no evidence of meningitis.

Emerging biological therapies for the treatment of age-related macular degeneration.

Introduction: Age-related macular degeneration (AMD) is the leading cause of blindness in individuals over age 50 in developed countries. Current therapy for nonexudative AMD (neAMD) is aimed at modifying risk factors and vitamin supplementation to slow progression, while intravitreal anti-vascular endothelial factor (VEGF) injections are the mainstay for treatment of choroidal neovascularization in exudative AMD (eAMD).

Areas Covered: Over the past decade, promising therapies have emerged that aim to improve the current standard of care for both diseases.

Intraoperative Retinal Changes May Predict Surgical Outcomes After Epiretinal Membrane Peeling.

Purpose: To investigate whether intraoperative retinal changes during epiretinal membrane (ERM) peeling affect anatomic or functional outcomes after surgery.

Methods: We measured retinal thickness using an intraoperative optical coherence tomography (iOCT) device in patients undergoing pars plana vitrectomy with membrane peeling for idiopathic ERM. Changes in intraoperative central macular thickness (iCMT) were compared with postoperative improvements in CMT and best-corrected visual acuity (VA).

Case Series on Initial Responses to Intravitreal Brolucizumab in Patients with Recalcitrant Chronic Wet Age-Related Macular Degeneration.

Purpose: To report a case series of initial responses to intravitreal brolucizumab in patients already undergoing anti-VEGF therapy for wet age-related macular degeneration.

Case Series: Six eyes (6 patients) with a history of wet age-related macular degeneration presented with either decline in vision or no improvement while undergoing treatment with anti-VEGF therapy - aflibercept or bevacizumab. Patients were switched to intravitreal brolucizumab.

Action of a minimal contractile bactericidal nanomachine.

R-type bacteriocins are minimal contractile nanomachines that hold promise as precision antibiotics. Each bactericidal complex uses a collar to bridge a hollow tube with a contractile sheath loaded in a metastable state by a baseplate scaffold. Fine-tuning of such nucleic acid-free protein machines for precision medicine calls for an atomic description of the entire complex and contraction mechanism, which is not available from baseplate structures of the (DNA-containing) T4 bacteriophage.

A case of Legionnaire's endophthalmitis.

To report a case of endophthalmitis associated with A 46-year-old, highly myopic male with a complex history of recurrent retinal detachments, macular hole, cataract surgery and an infected scleral buckle in the left eye, presented with pain, redness, hypopyon and vision loss in the left eye, 14 days following blunt head trauma. Empirical treatment for endophthalmitis with intravitreal injections of Vancomycin and Ceftazidime afforded minimal improvement. He developed recurrent hypopyon and underwent vitrectomy surgery with intravitreal antibiotic injections at the time of surgery and had improvement.

Building atomic models based on near atomic resolution cryoEM maps with existing tools.

The EMDataBank Validation Challenge was a challenging task for students newly introduced to the cryoEM and molecular modeling fields. However, the competition provided an effective space for student modelers to discover and explore the potentials of atomic modeling and refinement by practicing on published atomic structures. Here, by employing manual molecular modeling programs such as Coot, Phenix, and Chimera, we have regularized and improved three targets.
