<prompt> What is the role of Weigers ligament?Attachment of vitreous to the retinaAttachment of vitreous to orra serrataAttachment of vitreous to optic discAttachment of vitreous to posterior surface of lens  <response>: During childhood, Weigers ligament hyaloido capsular ligament helps in the attachment of vitreous to the posterior surface of the lens. Vitreous is attached to the internal limiting membrane of retina from 2mm anterior to the ora serrata to the edges of the optic disk. The attachment is quite firm at the macula and vitreous base and in peripapillary region. A hyaloid canal Cloquets canal runs down the the centre of the vitreous body from the optic disc to the posterior pole of the lens. Ref: Comprehensive Ophthalmology by AK Khurana, 4th edn, page 243
