Case Report: Acute Posterior Multifocal Placoid Pigment Epitheliopathy after SARS-CoV-2 Vaccination.

Significance: Acute posterior multifocal placoid pigment epitheliopathy is an uncommon inflammatory chorioretinopathy that has been reported after vaccination. This is the first reported case, to our knowledge, after vaccination for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a healthy adolescent boy.

Purpose: This report aimed to inform the eye care community about a possible ocular sequela of SARS-CoV-2 vaccination.

Correlation of changes in the mandible and retina/choroid vasculature of a rat model of BRONJ.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) causes bones of the mandible and maxilla to become necrotic and protrude into the oral cavity. Compromised blood supply to bone is also a feature of BRONJ. The design of this study was first to use our established technique of molar extraction and IV bisphosphonate injection to produce features of BRONJ in rats that mimic the human disease; second to confirm vascular changes in the mandible and eye using micro-CT of vascular casts, and image analysis of retina/choroid images; and third to show parallel bisphosphonate-induced changes in the structure and markers of the vasculature of the bone and eye.

The optometrist's role in the management of hypertensive crises.

Background: In hypertensive crises, ocular findings are pivotal to making correct management decisions. Joint National Committee on Prevention, Detection, and Treatment of High Blood Pressure (JNC-7) guidelines define hypertensive crises as blood pressure greater than 180/120 mmHg associated with signs or symptoms of target organ damage. Urgent cases are those without optic disc edema but that necessitate control within 24 to 72 hours.

Ocular syphilis associated with syphilitic resurgence in a human immunodeficiency virus-infected man.

Optometrists provide an important service to the community, often acting as the first health care provider a patient consults. Many patients will present with ocular complaints that have systemic associations. In addition to diabetes, hypertension, and rheumatologic disorders, optometrists can encounter the ocular manifestations of sexually transmitted diseases such as syphilis.
