👉 Macrohyporia is a condition in which the skin grows back on the inside of the eyelid, causing it to become very thick and heavy. This can occur due to an abnormality in the growth plate of the eyelid or as a result of other medical conditions such as autoimmune diseases. Macrohyporia occurs when the eyelids are too thin or thick for their normal function, leading to an accumulation of skin cells that form a layer over the eyelid.
