RESUMO
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.
RESUMO
Malignant glaucoma usually occurs after anterior segment surgery (typically after glaucoma surgery). The aim of this article is to report a case of spontaneous malignant glaucoma (SpMG), which required phacovitrectomy for resolution and to review the cases of SpMG reported in modern literature. Only nine cases were identified. SpMG has no gender predilection and age at onset seems to be lower (mean age 47â¯years) than in secondary malignant glaucoma (SeMG). Nearly in half of the reported patients (4 out of 9) the condition had a bilateral presentation. The risk factors that have been identified for SeMG (nanophthalmos, shallow anterior chamber, iris plateau, zonular laxity) are underrepresented in SpMG.
