Case Series: Glioblastoma Highlighting the Eye Care Provider's Role.

Significance: Although the incidence of glioblastoma is relatively low, patients presenting with this malignant central nervous system tumor will typically experience visual symptoms. Eye care providers are uniquely positioned to assist with the diagnosis of glioblastoma and to manage its associated visual symptoms.

Purpose: This case series will review the pathophysiology, diagnosis, treatment, and management of glioblastoma while highlighting the eye care provider's role over the course of the disease process.

Case Report: Atraumatic Orbital Emphysema after Bronchoscopy with Endobronchial Biopsy.

Significance: Orbital emphysema is a well-documented condition where air enters the orbital soft tissue typically because of direct or indirect trauma; however, atraumatic cases can be encountered. The following is a novel case report of acute unilateral atraumatic orbital emphysema 24 hours after bronchoscopy with endobronchial biopsy.

Purpose: To the best of the authors' knowledge, this is the first known case report of atraumatic orbital emphysema as a postprocedure complication of bronchoscopy with endobronchial biopsy in the literature.

Arteriole tortuosity associated with diabetic retinopathy and cholesterol.

Purpose: Earlier identification of diabetic eye disease is an important research effort. Retinopathy is widely acknowledged but retinal vessel changes are not evaluated as stringently. Here, we create a multivariate model for the association between retinal vessel tortuosity (RVT) and other health factors in patients with diabetes.
