The vitreous humor is a transparent connective tissue that fills the posterior segment of the eye. The word “vitreous” is derived from a Latin word “vitrum” which means glass. It is the largest anatomic structure in the human eye and it approximately 4 mL in volume. It is located between the lens and the retina and occupies more than three-quarters of the total ocular volume.[1],[2],[3]

The anterior surface of the vitreous is known as the anterior hyaloid face or membrane. The anterior hyaloid membrane is a delicate thin-layered structure that runs from the pars plana to the posterior part of the lens. Posteriorly, it is separated from the retina by the internal limiting membrane composed of Type IV collagen.[3],[4],[5],[6]


  Case Report Top


A52-year-old female presented with the complaint of diminution of vision in the left eye for the last 2 months following blunt ocular trauma by a bamboo stick. Her visual acuity at presentation was counting fingers at 3 m. Slit-lamp examination showed a partial nasal subluxation of the early cataractous lens with zonular dialysis from 12 to 5 o'clock position. The lens was held in this state with two strands of zonules originating from around 2 o'clock position [Figure 1]a and [Figure 1]b. The undulating movement of the anterior hyaloid membrane could be appreciated very clearly [Video 1]. The patient underwent successful par plana vitrectomy, lensectomy, and scleral-fixated intraocular lens implantation with full visual recovery. This is first of its kind video documentation of undulating movement of the anterior hyaloid membrane.
