Vitreociliary Block in a Patient With Uveitis and Previous Laser Posterior Capsulotomy

To report a case of vitreociliary block (VCB) six months after a laser posterior capsulotomy (LPC).

A 25-year-old man with uveitis, retinal vasoproliferative tumor, cataract, and acute angle-closure glaucoma due to pupillary seclusion, which required laser iridotomies, implantation of an Ahmed valve, phacoemulsification, and LPC. Six months after capsulotomy, he presented a generalized flattening of the anterior chamber (AC) and ocular hypertension, with patent iridotomies. Hyperechoic anterior hyaloid and hypoechoic spaces in the vitreous were seen in ultrasound imaging. The VCB did not respond to pharmacological treatment and was solved immediately after laser hyaloidotomy.

There are three cases of VCB after LPC described in the literature. Our patient presented a chronic inflammatory process that generated an inflammatory membrane at the level of the anterior hyaloid with adhesion to the ciliary processes, causing posterior misdirection of the aqueous humor, decreased permeability of the anterior hyaloid, and finally, VCB.
