How Do You Spell MEMBRANA FUSCA?

1. Membrana fusca is a Latin term that translates to "dark membrane" in English. It is a specialized layer of tissue found in the eye, specifically within the choroid, which is located between the retina and the sclera (outer layer of the eye).

   The membrana fusca is characterized by its dark brown to black pigmentation due to the presence of melanocytes, which produce the pigment melanin. This gives the membrane its distinct coloration, which helps to absorb and block excessive light entering the eye, preventing glare and ensuring optimal visual clarity.

   This membrane serves several important functions within the eye. Firstly, it helps to reduce internal reflections and scatterings of light, thereby enhancing the sharpness and contrast of the images that form on the retina. Additionally, the membrana fusca acts as a barrier, preventing the unwanted passage of light through the choroid and maintaining the focused image on the retina.

   Pathological changes or abnormalities in the membrana fusca can occur, such as its thinning or loss of pigmentation. These changes may be associated with certain eye conditions, such as age-related macular degeneration or ocular melanoma. Thus, the membrana fusca plays a crucial role in maintaining optimal eye function and visual acuity.

2. The pigment layer between the chorioid and the sclera of the eyeball.
