Vitrectomy-phacoemulsification-vitrectomy for the management of aqueous misdirection syndromes in phakic eyes.

OBJECTIVE: To describe vitrectomy-phacoemulsification-vitrectomy, a sequential 3-step surgical approach, in the management of malignant glaucoma/aqueous misdirection syndromes in phakic eyes. DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Five eyes (4 angle-closure glaucoma and 1 open-angle glaucoma) of 5 patients with mean age of 66 years (range, 56-78). Four patients presented with aqueous misdirection syndrome and 1 patient presented for cataract extraction, having previously had malignant glaucoma in the fellow eye after phacoemulsification surgery. INTERVENTION: The operation performed had three steps: vitrectomy, phacoemulsification, and vitrectomy. Step 1: Preliminary vitrectomy involved limited core vitrectomy to "debulk" the vitreous and soften the eye. Step 2: Phacoemulsification was performed in a standard manner. Step 3: Residual vitrectomy, zonulohyaloidectomy and peripheral iridectomy (if not already present) were performed to create a free communication between the posterior and anterior segments. MAIN OUTCOME MEASURES: Intraocular pressure, visual acuity, biomicroscopic anterior chamber depth, and complications. RESULTS: The time interval between the onset of malignant glaucoma and surgery ranged from 2 weeks to 3 months. All 4 patients with aqueous misdirection syndrome had relief of the aqueous misdirection postoperatively with anterior chamber deepening. Intraocular pressures on day 1 ranged from 6 to 28 mmHg (mean 15.6, mmHg), and at the last visit ranged from 8 to 30 mmHg (mean, 20.4 mmHg). One eye developed an early choroidal serosanguinous effusion requiring drainage. CONCLUSIONS: The vitrectomy-phacoemulsification-vitrectomy approach was effective in this pilot series in the management of aqueous misdirection syndromes and malignant glaucoma in phakic eyes.

Perforated corneal hydrops treated with sulfur hexafluoride (SF6) gas and tissue adhesive.

PURPOSE: To report a case of a perforated acute hydrops in a mentally retarded patient that was successfully managed with intracameral sulfur hexafluoride gas and cyanoacrylate tissue adhesive. METHODS: Interventional case report. RESULTS: A 14-year-old mentally retarded male patient with keratoconus presented with a perforated acute hydrops. A bandage contact lens was applied. However, following a large emesis 2 days later, the aqueous leak worsened with shallowing of the anterior chamber. Under general anesthesia, sulfur hexafluoride was injected to reform the anterior chamber and cyanoacrylate tissue adhesive was applied to the perforated site and covered by a bandage contact lens and temporary tarsorrhaphy. A follow-up examination at 1 month showed a formed anterior chamber with tissue adhesive in situ and no aqueous leak. CONCLUSIONS: The successful use of intracameral sulfur hexafluoride and tissue adhesive in the management of perforated acute hydrops may avoid emergency tectonic penetrating keratoplasty and reduce potential complications in the poorly cooperative patient.

Fibrin glue in the management of corneal melt.

Human fibrin glue aids physiological healing thereby reducing corneal vascularization and scarring compared with cyanoacrylate tissue adhesive. A 40-year-old intellectually disabled man with a corneal melt is reported who was managed successfully using human fibrin glue, alleviating the need for emergency penetrating keratoplasty.

Pellucid marginal degeneration and scleroderma.

Systemic scleroderma is a progressive multi-system connective tissue disease. Ocular involvement includes keratoconjunctivitis sicca, progressive shallowing of conjunctival fornices, peripheral ulcerative keratitis and eyelid tightness. No association has been reported between scleroderma and pellucid marginal degeneration, which is a rare bilateral corneal ectasia. Pellucid marginal degeneration is characterised by non-inflammatory and progressive peripheral corneal thinning inferiorly, often with high against-the-rule astigmatism. We report a case of a 55-year-old woman with systemic scleroderma who presented with rapidly progressing against-the-rule astigmatism. The differential diagnosis of peripheral corneal thinning and the challenge of the surgical management of pellucid marginal degeneration are briefly discussed.
