1/16. Loss of iridolenticular contact in eyes with exfoliation syndrome may protect against glaucoma.PURPOSE: To provide evidence for the hypothesis that dynamic iridolenticular contact predisposes to the development of glaucoma in exfoliation syndrome (XFS). methods: We present four patients with bilateral XFS and unilateral exfoliation glaucoma (XFG) whose normotensive eyes had suffered traumatic loss of dynamic iridolenticular contact. RESULTS: All 4 patients had bilateral XFS and developed XFG only in the untraumatized eyes. One patient had loss of iridolenticular contact in the traumatized eye, two had a nonreactive pupil, and one had had intracapsular cataract extraction at age 28. CONCLUSIONS: Loss of dynamic iridolenticular contact may help to protect against development of glaucoma in eyes with XFS.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/16. Peritubular filtration as cause of severe hypotony after Ahmed valve implantation for glaucoma.PURPOSE: To report peritubular filtration as the cause of severe hypotony after Ahmed valve implantation. methods: Interventional case report. In a 65-year-old man with primary open-angle glaucoma, ultrasound biomicroscopy was used to image the peritubular region of his right eye that had severe hypotony during the early postoperative period after an Ahmed valve implantation. RESULTS: The ultrasound biomicroscopy examination showed peritubular filtration. Additional surgery consisting of tube extraction, closure of the previous insertion opening, reformation of the anterior chamber with viscoelastic, and reintroduction of the tube through a new paracentesis was performed to solve this complication. Twenty-four hours postoperatively, the intraocular pressure increased to 10 mm Hg. During the 6-month follow-up, the mean intraocular pressure was 16.36 mm Hg (standard deviation, 1.45). CONCLUSION: The possibility of peritubular filtration should be considered in eyes with severe hypotony after restrictive valve implantation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/16. Preservation of residual field after surgical lowering of intraocular pressure.A 52-year-old Caucasian woman with pigmentary glaucoma underwent a left cyclodiathermy procedure for raised intraocular pressure (IOP) in 1962 and right sclerectomy the following year. Over 25 years later a low IOP was still maintained though pilocarpine was needed in the left eye. After a left cataract extraction with insertion of a posterior chamber lens, field loss had not progressed very much in either eye though the visual acuity was reduced in the more affected eye. Both drainage operation and a cyclodestructive procedure controlled IOP over a long period of time in this patient and were associated with only a very gradual progression of field loss.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/16. Asymmetric pigmentary glaucoma resulting from cataract formation.Pigment dispersion syndrome usually manifests bilaterally, and asymmetric involvement is unusual. When asymmetry is present, the eye with greater involvement may have an additional exacerbating condition or the eye with less involvement may be protected. Analysis of such cases should further elucidate the mechanism of the disorder and its development and regression. We examined four patients in whom unilateral cataract formation or extraction was associated with reduced clinical signs of pigment dispersion syndrome in the affected eye. Cataract formation, by inducing relative pupillary block, appears to decrease or prevent the manifestation of pigment liberation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/16. Nanophthalmic cataract extraction.Nanophthalmos is a rare ophthalmic condition with potential sight-threatening complications. In addition, nanophthalmic eyes have a high incidence of intraoperative and postoperative complications, including uveal effusion and retinal detachment. Prophylactic measures to prevent these complications may be used. The case is presented where cataract extraction for a nanophthalmic eye was performed from a posterior approach in combination with a pars plana vitrectomy and gas procedure. To the authors' knowledge, this method of cataract extraction has not been reported before for this condition.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |

7/16. 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.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/16. Posterior chamber intraocular lenses after extracapsular cataract extraction in patients with aniridia.Visual rehabilitation of patients with aniridia and progressive cataract is a challenging clinical problem. Reduced corneal transparency, limitations of iris support, and decreased zonular integrity may make extracapsular cataract surgery difficult. Four patients with familial aniridia had substantial visual improvement after successful extracapsular cataract extraction (ECCE) with implantation of capsular-fixated posterior chamber intraocular lenses (PC IOLs). In one patient, it was combined with trabeculectomy to treat chronic open-angle glaucoma. Posterior chamber IOLs can be safely implanted in the aniridic eye normalities in the anterior segment.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
9/16. Enhancing filtration in the early postoperative trabeculectomy refractory to digital massage.Digital massage often can be used to lower intraocular pressure (IOP) after trabeculectomy or trabeculectomy combined with extracapsular cataract extraction and intraocular lens implantation. However, occasionally filtration, and thus IOP reduction, is refractory to massage. We present a pressure-lowering technique in which focal pressure is applied adjacent to the trabeculectomy flap firmly enough to indent the sclera and induce bleb formation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/16. 'In-the-bag' hyphaema--a rare complication of posterior chamber lens implantation.A 72-year-old woman developed a hyphaema on the first postoperative day after a combined trabeculectomy and extracapsular cataract extraction with posterior chamber intraocular lens implantation. On the second day the blood had redistributed to accumulate 'in the bag' posterior to the intraocular lens and had formed a fluid level. Postural drainage helped to clear the hyphaema from both locations, with no short-term effect on visual function or the filtering bleb.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
