“…They performed an emergency iridectomy and local zonulectomy using a 25-gauge vitreous cutter and achieved effective results. Byrnes et al [22] reported persistent or recurrent ciliary block glaucoma in 50% of phakic patients and in 10% of pseudophakic eyes in their series of patients that underwent pars plana vitrectomy for misdirection syndrome. The posterior diversion of the aqueous humor by a ciliovitreo-lenticular block caused an unexpected anterior hyaloid clog between the ciliary processes.…”

Purpose To determine the effectiveness of iridectomy, capsulotomy and anterior vitrectomy through the anterior chamber to treat misdirection syndrome in pseudophakic nanophthalmic eyes. Methods This was a non-comparative study of seven nanophthalmic eyes from four consecutive patients. All eyes developed misdirection syndrome after successful cataract surgery. Treatment for misdirection syndrome involved capsulotomy and anterior vitrectomy through a peripheral iridectomy from the anterior chamber using a 25-gauge vitreous cutter. The best-corrected visual acuity, intraocular pressure and anterior and posterior segment findings were recorded before and after surgery. Results Resolution of the aqueous misdirection was achieved in all but one eye. The single case of recurrence was observed after a mean follow-up of 45.6 ± 21.5 months and was caused by closure of the capsule hole by Elschnig's pearls. This eye was successfully treated by enlargement of the lens capsule hole with a vitreous cutter. The mean intraocular pressure before surgery was 28.7 ± 4.4 mmHg, and this was significantly reduced to 13.7 ± 1.3 mmHg at the final visit. All but one patient, who had uveal effusion, maintained their best-corrected visual acuity. Conclusion In this study, we investigated an alternative option for the treatment of misdirection syndrome in nanophthalmic eyes. We undertook a lens capsulotomy and anterior vitrectomy through a peripheral iridectomy from the anterior chamber using a 25-gauge vitreous cutter, which was able to create a communication hole between the anterior and posterior chambers.

“…O tratamento do glaucoma maligno pseudofácico tem sido conduzido de diversas maneiras, como: ablação a laser dos processos ciliares (18,19) , hialoidotomia e capsulotomia posterior com Nd-Yag laser (20)(21)(22)(23) , e ainda têm sido propostos diversos tratamentos cirúrgicos como vitrectomia anterior via pars plana (24)(25)(26) . No caso relatado, o tratamento instituído obteve resultado satisfatório com total reversão do glaucoma como demonstra a figura 2.…”

RESUMOO glaucoma maligno é uma doença caracterizada por pressão intraocular elevada com câmara anterior rasa na presença de iridectomia periférica patente. Na sua forma clássica, o glaucoma maligno é raro, e representa uma das mais sérias complicações da cirurgia fistulizante em pacientes com ângulo estreito ou glaucoma de ângulo fechado. O presente trabalho relata um caso de uma paciente do sexo feminino que desenvolveu crise de glaucoma por bloqueio ciliar (maligno) precipitada pela realização de curva tensional diária de pressão intraocular com tonômetro de contorno dinâmico.Descritores

“…It is a successful surgical treatment for malignant glaucoma (42)(43)(44)(45)(46) . The vitreous punction and aspiration is performed via pars plana four mm from the limbus with an 18-gauge needle and is associated with the reformation of the anterior chamber with saline or viscoelastic substance.…”

“…(42) For some authors (43) , pars plana vitrectomy showed better results in resolving ciliary block glaucoma in pseudophakic eyes than in phakic eyes. In phakic eyes, lensectomy may be considered for marked corneal edema, for dense cataract, or when the anterior chamber do not deepen during vitrectomy (44) . More recently, other authors (45) have performed pars plana vitrectomy.…”

RESUMOO objetivo deste artigo de revisão é discutir o conhecimento atual sobre a fisiopatologia e as abordagens diagnóstica, terapêutica e profilática do glaucoma maligno. Este tipo de glaucoma pode ocorrer após diferentes procedimentos cirúrgicos. Pode ocorrer em olhos áfacos, fácicos e pseudofácicos e se desenvolver espontaneamente em olhos não-operados, ou associado ao uso de mióticos. Atualmente, a biomicroscopia ultrassônica tem revelado muitos achados úteis e importantes para o diagnóstico e o tratamento do glaucoma maligno. Ele ocorre com maior frequência em olhos pequenos nos quais as medidas pré-operatórias da profundidade da câmara anterior e do comprimento axial são extremamente importantes para a sua profilaxia e diagnóstico.Descritores: Glaucoma; Glaucoma de ângulo fechado /diagnóstico; Glaucoma de ângulo fechado /classificação; Glaucoma de ângulo fechado /fisiopatologia; Glaucoma de ângulo fechado/terapia; Glaucoma de ângulo fechado/cirurgia; Glaucoma de ângulo fechado/ultrasonografia; Profilaxia
