Late leakage of filtering bleb in a patient with orbital pseudotumor.

PURPOSE To report an unusual case of spontaneous late leakage of filtering bleb in a patient with orbital pseudotumor. METHODS Single case report. RESULTS A 53-year-old woman developed spontaneous leakage of bleb in her right eye 23 years after trabeculectomy with application of mitomycin-C (MMC). Two weeks later, her symptoms were blurring of vision, increasing redness, and dull ocular pain in the right eye. The inflammatory signs were suggestive of endophthalmitis, orbital cellulites, or pseudo-tumor. Absence of ophthalmoplegia, fever, and raised white cell count, together with the computed tomographic scan finding, confirmed the diagnosis of orbital pseudotumor. She responded well to oral steroids. CONCLUSIONS Orbital pseudotumor may initially present with spontaneous late leakage in a bleb augmented by MMC. Orbital pseudotumor should be added to the list of differential diagnoses when facing a patient with an inflamed, chemotic, proptotic eye in the presence of a late bleb leak.
