macula sacÂ´culi a thickening on the wall of the saccule where the epithelium contains hair cells that receive and transmit vestibular impulses. macula utriÂ´culi a thickening in the wall of the utricle where the epithelium contains hair cells that are stimulated by linear acceleration and deceleration and by gravity.
The macula is the special area at the center of the retina, which is responsible for clear, detailed vision. The macula normally lies flat against the back of the eye, like film lining the back of a camera. An epiretinal membrane is a condition where a thin sheet of scar tissue grows on the surface of the retina.This scar tissue can contract causing the macula to become wrinkled and may result in swelling of the retina and vision changes.f this scar-like tissue contracts, it can causes the retina to wrinkle or pucker. Many other eye conditions can be associated with the formation of an epiretinal membrane including trauma, diabetic retinopathy, retinal tears, prior retinal detachment, and ocular inflammation (uveitis).
