This was a 28-year-old mentally-challenged girl with underlying congenital Rubella syndrome. She was bilaterally
aphakic after congenital cataract surgery. She then developed bilateral aphakic glaucoma and had to undergo
multiple glaucoma filtering surgeries. The most recent procedure she had undergone for her left eye was a second
Ahmed valve implantation with an overlying sclera patch. Postoperatively, intraocular pressure was well controlled.
However, nine months later, slit lamp examination revealed the tube was adherent to the overlying cornea with
surrounding deep and superficial cornea vascularization. Siedel test was negative and intraocular pressure was
normal. Subsequently the tube was removed but the plate was left in situ.
