Vitreous Anatomy, Anterior PVR, and Hypotony

  • D. Ruiz-Casas


The anterior hyaloid presents a complex anatomy and is involved in accommodation by inducing traction on the vitreous base that may be associated with retinal detachment incidence and recurrence.

Anterior hyaloid dissection can be performed at Salzman’s hiatus to achieve a complete vitrectomy.

Proliferative vitreoretinopathy contracts the anterior hyaloid inducing ciliary body detachment and anterior retinal traction. Scarred anterior hyaloid dissection is needed to deal with chronic hypotony and anterior retinal loops.
