MAESTRINI, Heloisa Andrade et al. Scleral injure caused by needling revision with adjunctive mytomicin-C: case report. Arq. Bras. Oftalmol. [online]. 2011, vol.74, n.2, pp.134-135. ISSN 0004-2749.

A 70-year-old female patient underwent cataract and glaucoma surgery on her left eye in 1996. Eleven years later, we performed two bleb needling revisions with adjunctive mytomicin-C, in order to decrease an uncontrolled intraocular pressure of 32 mmHg. After the second needling, she developed severe overfiltration, with flat anterior chamber, choroidal effusion, and impending corneal decompensation. Conservative treatment with cycloplegic and corticosteroid eye drops, acetazolamide and therapeutic contact lenses was unsuccessfully tried. Anterior chamber reformation was successively tried with air, 4% ophthalmic viscosurgical device and 1% sodium hyaluronate, with only temporary results. Compressive sutures above the overfiltering bleb were applied, unsuccessfully. In order to avoid additional corneal endothelium damage, a surgical bleb revision was performed and revealed a large area of ciliary body and choroidal exposure under the conjunctiva. It was covered by a donor scleral patch graft providing successful resolution. Nevertheless, we had to reintroduce hypotensive eyedrops. While bleb needling is a relatively safe and effective procedure, ophthalmologists should be aware of the possibility of potentially serious complications, such as in this case report.
