What is the function of the vitreous?

• A. Support lens anteriorly
• B. Maintain globe shape
• C. Transmit light to retina
• D. Support retina posteriorly

Answer: (D)

The vitreous mainly serves to provide posterior support for the retina, helping keep it pressed against the choroid and in stable contact with the back of the eye. This supportive scaffold is crucial for maintaining proper retinal position and tear resistance; when the vitreous slows its gel-fiber network with age and peripherally detaches, traction on the retina can lead to tears or detachment. While the vitreous is transparent and does help transmit light to the retina and contributes to maintaining the globe’s shape, the most specific and important function in relation to retinal health is its posterior support.
