De Retinae Monstris

"De Retinae Monstris" refers to a historical medical concept suggesting that some eye abnormalities or large, abnormal "monstrous" retinas were caused by a congenital or developmental anomaly. In essence, it describes a situation where the retina—the light-sensitive layer at the back of the eye—appears significantly enlarged, misshapen, or abnormal, leading to vision issues. Historically, this term was used to describe rare and unusual retinal conditions that seemed to result from developmental defects, though modern medicine now understands these conditions with more precise terminology and explanations.
