Bilateral Panuveitis with Occlusive Vasculitis following Coronavirus Disease 2019 Vaccination.

Purpose: To report a case of bilateral panuveitis and occlusive vasculitis following COVID-19 vaccination.

Study Design: Case report.

Results: A 41-year-old otherwise healthy male presented with progressive vision loss and floaters starting 48 hours after a first dose of COVID-19 vaccine.

Helicobacter pylori Infection of the Gastric Mucosa and Ocular Adnexa-Lack of Association With Ocular Adnexal Lymphoma.

Purpose: Helicobacter pylori could theoretically induce ocular adnexal lymphoma (OAL) via 2 mechanisms: the first is that of infection within the ocular adnexa and the second is that of infection within the gastric mucosa, leading to the malignant transformation of lymphocytes that migrate to the ocular adnexa, forming a primary "ectopic" cancer. This study investigated if an association exists between gastric H. pylori or ocular adnexal H.

Streamlined approach to mapping the magnetic induction of skyrmionic materials.

Recently, Lorentz transmission electron microscopy (LTEM) has helped researchers advance the emerging field of magnetic skyrmions. These magnetic quasi-particles, composed of topologically non-trivial magnetization textures, have a large potential for application as information carriers in low-power memory and logic devices. LTEM is one of a very few techniques for direct, real-space imaging of magnetic features at the nanoscale.

A case of panuveitis with hypopyon due to presumed ocular leishmaniasis in a HIV patient.

Background: Post-kala-azar dermal leishmaniasis is a well-known immunologic cutaneous reaction. There are few case reports of ocular leishmaniasis. It is a sight-threatening condition that needs to be rapidly recognized and treated to avoid permanent visual loss.

Reducing wait time for cataract surgery: comparison of 2 historical cohorts of patients in Montreal.

Objective: A cataract efficiency program was implemented in Montreal in 2003 to decrease surgery wait time. Our goal was to determine whether health, adverse events during wait time, and outcome of patients presenting for cataract surgery differed from 1999 to 2006 in Montreal.

Design: Prospective preoperative and postoperative observational study performed at 2 time points 6 years apart.

Cataract-related vision loss and depression in a cohort of patients awaiting cataract surgery.

Objective: As provinces consider what an acceptable cataract surgery wait time should be, research is needed on the risk of adverse events, such as depression, while waiting for care. We sought to determine whether worse visual acuity is related to depressive symptoms in patients waiting to have cataract surgery.

Design: Cohort study.

Topical effect of various agents on gelatinase activity in the tear film of normal dogs.

Objective: To evaluate the topical effect of various agents, currently used in the treatment of melting ulcers, on gelatinase activity present in the tear film of normal dogs.

Animal Studied: Eight normal adult beagles.

Procedures: Each animal received the following agents: cyclosporine A 1%, N-acetylcysteine 10%, ciprofloxacin 0.
