Purpose: To describe a case of bilateral pseudophakic malignant glaucoma treated with a new variant of irido-zonulo-hyaloid-vitrectomy. Observations: A patient who developed refractory bilateral pseudophakic malignant glaucoma underwent an irido-zonulo-hyaloid-vitrectomy via the anterior chamber in both eyes, one 2-months apart from the other. The procedure involved the use of an 18 Gauge needle to perform a straight vertical irido-zonulo-hyaloidotomy and a 25 Gauge vitreous cutter to complete the vitrectomy. The intraocular pressure was recorded on day 1, day 7, day 14, then monthly until 6 months postoperatively, whereas an ultrasound biomicroscopy of the anterior chamber was performed on day 1 and 6 months after the operation. The malignant glaucoma resolved in both eyes with no intra- nor post-operative complications. At 6 months from the surgeries none of the eyes developed recurrences. Conclusions: The new variant of irido-zonulo-hyaloid-vitrectomy we propose for the management of refractory pseudophakic malignant glaucoma resulted to be a safe and effective technique.
