An 8-year old child with a congenital glaucoma status post non-valved Aurolab aqueous drainage implant (AADI) surgery in the left eye (LE) presented for routine review after 5 years. LE clinical examination revealed Haab's striae and an AADI tube in the anterior chamber (AC) with the best corrected visual acuity of 6/12 and an intra-ocular pressure of 18 mmHg. Slit beam evaluation and anterior segment optical coherence tomography (OCT) certainly confirmed the close proximity of the tube with the corneal endothelium throughout its course [Figure 1]a, [Figure 1]b, [Figure 1]c. Straightening of the tube, migration, and retraction are known complications of glaucoma drainage device implantation in children owing to the growing globe. Ideally, the tube has to enter the AC through the trabecular meshwork below the Schwalbe's line to avoid tube endothelial contact. Morever, in the eyes with opaque limbus, it is difficult to objectively judge the same, and hence, intra-operative gonioscopy or anterior segment OCT imaging could provide a real-time assessment of the tube entry site.,
