Despite the fact that OCT angiography (OCTA) does not technically qualify as multimodal imaging per se, it does offer several modes of visualization from a single scan, including an angiogram, a structural picture, and en face imaging with boundary specific segmentation. The use of OCTA can assist doctors in communicating to patients with geographic atrophy who are susceptible to exudation the necessity for routine follow-up. Clinicians can rule out artifacts by analyzing the flow overlay on the OCTA cross-section. If the flow isn’t where it should be for the illness, it’s probably an artifact.

The article proposes a computational model to account for the complex interaction between stimulus size, duration, and retinal cones-to-retinal ganglion cells ratio. The findings challenge the assumption of a constant critical number of retinal ganglion cells with respect to the enlargement of the critical area of summation with eccentricity in the macula, proposing instead a constant critical total retinal input. The research has implications for understanding perimetric sensitivity and modeling disease, particularly glaucoma.

When atypical AMD is suspected, additional multimodal imaging and a more detailed medical history are required to establish the correct diagnosis. The medical history, clinical examination, and retinal imaging findings of a 69-year-old White man with a long-standing medical history of schizophrenia, bilateral visual decline, nyctalopia, and blurred vision were sufficient evidence for the doctors to establish a presumed diagnosis of thioridazine retinal toxicity. Although it is a rare diagnosis due to the introduction of newer medications, patients with an underlying psychiatric history and atypical retinal findings on examination may have been or are currently taking the culprit psychotropic medication.
