Tube Retraction in Iridocorneal Endothelial Syndrome

Glaucoma secondary to iridocorneal endothelial (ICE) syndrome is refractory to medical treatment, and its management is always challenging. Figure 1a shows the clinical photo of a 42-year male patient with ICE syndrome in the left eye (LE) post failed trabeculectomy, who underwent Ahmed glaucoma valve with tube in sulcus placement for control of intra-ocular pressure (IOP). Figure 1b shows the clinical photo taken at 4-month post-operative follow-up, where the retracted tube (white circle) is seen sub-conjunctivally with an elevated IOP of about 32mmHg. He was treated with fixed combination therapy of dorzolamide hydrochloride 2% and timolol maleate 0.5% twice a day in LE. The possible reasons for tube retraction include inadvertently cut tube, kinked tube, or posterior migration of the implant due to faulty suturing of the episcleral plate to the sclera.[1,2]Figure 1: (a) Clinical photo of the LE showing multiple areas of iridocorneal adhesions, with surgical iridectomy at 12'0 clock, failed bleb, and superotemporal Ahmed glaucoma valve implant.
