Malignant glaucoma (ciliary block) was initially reported as developing after surgery for glaucoma. Subsequently, associations with trauma, inflammation and the use of miotic agents as well as spontaneous occurrence have been noted. Misdirected aqueous fluid causes forward movement of the lens/iris diaphragm, shallowing the central and peripheral anterior chamber rising the intraocular pressure. We report a case of this type of glaucoma developed in one patient with primary open angle glaucoma with preexisting central retinal vein occlusion following trabeculectomy. Although the relationship may be coincidental, we concluded that central retinal vein occlusion may be a risk factor for the development of malignant glaucoma following filtering surgery.LA: Spanish
