Purpose: Patients with non-proliferative macular telangiectasia type 2 (MacTel) have ganglion cell layer (GCL) and nerve fibre layer (NFL) loss, but it is unclear whether the thinning is progressive. We quantified the change in retinal layer thickness over time in MacTel with and without diabetes.
Methods: In this retrospective, multicentre, comparative case series, subjects with MacTel with at least two optical coherence tomographic (OCT) scans separated by >9 months OCTs were segmented using the Iowa Reference Algorithms.
Background: Iatrogenic malnutrition is a significant burden to patients, clinicians, and health care systems. Compared with well-nourished patients, underfed patients (those who receive less than 80% of their daily energy requirement) have more adverse outcomes related to nutritional status. Volume-based protocols allow for catch-up titrations, are consistently superior to rate-based protocols, and can be implemented in most settings.

Background And Objective: Color fundus photography is an important imaging modality that is currently limited by a narrow dynamic range. We describe a post-image processing technique to generate high dynamic range (HDR) retinal images with enhanced detail.
Patients And Methods: This was a retrospective, observational case series evaluating fundus photographs of patients with macular pathology.
Purpose: To investigate the distribution of genotypes and natural history of ABCA4-associated retinal disease in a large cohort of patients seen at a single institution.
Design: Retrospective, single-institution cohort review.
Participants: Patients seen at the University of Iowa between November 1986 and August 2022 clinically suspected to have disease caused by sequence variations in ABCA4.
Purpose: Choroideremia is an X-linked choroidopathy caused by pathogenic variants in the gene. It is characterized by the early appearance of multiple scotomas in the peripheral visual field that spread and coalesce, usually sparing central vision until late in the disease. These features make quantitative monitoring of visual decline particularly challenging.
