Pupillary Block With Posterior Chamber Intraocular Lenses

Pupillary block following posterior chamber intraocular lens implantation in adults

“…However, there are only a few reports of pupillary block consequent to posterior IOL implantation. [1][2][3] The largest such series in adults (12 patients) was reported, to the best of our knowledge, in 1987 by Samples et al 4 Several years later, Vajpayee et al 5 The aim of the present study was to describe our 10 year experience with pupillary block complicating posterior intraocular (IOL) implantation. The possible underlying mechanisms, management, and final outcome are discussed.…”

Pseudophakic Pupillary Block with Acute Angle Closure Following Vitrectomy in an Adult Microphthalmia with Diabetic Retinopathy: Case Report

“…However, it can occur immediately or years after uneventful PC IOL implantation in eyes with excessive postoperative inflammation leading the formation of posterior synechiae/adhesions between the pupillary margins and the anterior surface of IOL. [1] Diabetes mellitus (by breaking the blood-aqueous barrier [BAB]), retained lens material behind the iris, free vitreous block, and blockage by SO are the risk factors for the block. [2][3][4] Microphthalmia, characterized by the shallow AC and a thick sclera, is a known risk factor for the pupillary block after cataract extraction surgery.…”

“…The block rarely occurs when an IOL is implanted into the bag. However, it can occur immediately or years after uneventful PC IOL implantation in eyes with excessive postoperative inflammation leading the formation of posterior synechiae/adhesions between the pupillary margins and the anterior surface of IOL [ 1 ]. Diabetes mellitus (by breaking the blood-aqueous barrier), retained lens material behind the iris, free vitreous block, and blockage by SO are the risk factors for the block [ 2 – 4 ].…”

Pupillary block due to reverse implantation of a sulcus intraocular lens

“…1,2 However, it can also occur after posterior chamber IOL implantation and may be related to several factors, including placement of the IOL in the ciliary sulcus resulting in an alteration of the anterior chamber angle, 3 disruption of zonular fibers intraoperatively leading to vitreous presentation in the anterior chamber, 4 and exacerbation of a preexisting shallow anterior chamber. The onset can occur from a few days to several months postoperatively.…”

“…The onset can occur from a few days to several months postoperatively. 2 We present a case of pupillary block secondary to reverse implantation of an IOL in the ciliary sulcus leading to chronic angle-closure glaucoma (ACG) and acute pupillary block.…”
