MS-2607

A 59-year-old man is referred to an ophthalmologist by his physician due to complaints of blurry vision and floaters. He has a medical history of type II diabetes and hypertension.

During the slit lamp examination, the ophthalmologist observes a posterior vitreous detachment.

The ophthalmologist explains that the cause of his symptoms is likely due to a defect in the collagen that makes up the vitreous membrane, leading to its separation from the retina.

What type of collagen is the ophthalmologist referring to?
