Macropsia is a condition where objects appear larger than they actually are. There are several synonyms for this term, including megalopsia, gigantism, and pelopsia. Megalopsia is a condition where objects appear larger than their actual size, making things appear monstrous and overwhelming. Gigantism, on the other hand, refers to a condition where there is an excessive growth of body mass and height. Pelopsia, similarly to macropsia, is a visual disorder where objects appear closer than they actually are. These terms are often used interchangeably, but they have subtle differences in their definitions. Overall, all these synonyms are indicative of visual perception abnormalities that can impact an individual's daily life.
