     [ABSTRACT] Objective: To investigate the clinical effect of extracapsular cataract extraction combined with goniosynechialysis in treatment of acute angle closure

glaucoma with cataract. Methods: Thirty four patients (37

    eyes) were subjected to this management. The anterior chamber

    depth, visual acuity , configuration of chamber anger, and intraocular pressure were determined. Results: After a mean postoperative follow up of 180 days, the best corrected

    visual acuity was improved in 28 cases (30 eyes). The mean anterior chamber depth was 1.674 ? 0.478 mm pre

    operatively and 3.412 ? 0.169 mm at post operative 30 days

    (t = 6.743, P <0.001). The intraocular pressure was decreased from a pre operative of 28.436 ? 3.325 mmHg to a

    postoperative 7 day of 13.983 ? 5.196 mmHg (t = 5.263, P

    <0.001). Angles of the anterior chamber were opened at post

    operative 30 days in all 34 patients. The visual field was not significantly changed in 15 patients at six months after operation. Conclusion: Extracapsular cataract extraction

    combined with lysis of the synechiae is safe and effective for acute angle closure glaucoma.

     [KEY WORDS] Extracapsular cataract extraction;

    Goniosynechialysis; Glaucoma; Angle closure glaucoma is a

    form of pathological intraocular pressure and visual

    impairment associated with the common blinding eye disease. Angle-closure glaucoma with shallow anterior chamber, narrow angle, and axial length and short features, which increase with age, its relative pupillary block caused by thickening of the lens, while the crystals can be removed to deepen the anterior chamber and open angle Adhesion yet , postoperative intraocular pressure in some patients obtain control, but the angle in patients with solid adhesion did not improve, intraocular pressure was still higher than normal levels. We have acute angle-closure glaucoma with cataract underwent

    cataract extraction and intraocular lens implantation goniosynechialysis will be the clinical indicators before and after surgery to compare the results now reported as follows.

     1 Data and methods

     1.1 General Information option from January 2003 to December 2005 at the Shandong University Qilu Hospital, diagnosed with acute angle-closure glaucoma with cataract

    patients 34 cases (37), of which 11 males (13), female 23

    cases ( 24), 57 76 years, an average of 64 years of age; lens cortical opacity in 23 cases (26), lens nuclear opacity in 6 cases (6 eyes), posterior subcapsular cortical opacity 5 cases

(5 eyes). Surgery before the surgery eye (visual acuity "0.3)

    for routine vision, intraocular pressure, central anterior chamber depth, gonioscopy line perimetry. The higher preoperative IOP, intraocular pressure lowering treatment given to drug. Depth and degree of anterior chamber intraocular lens-specific A measurement applications

    ophthalmic ultrasound measured (the United States, STORZ COMPUSCAN LT), were continuously measured 16 times, the data processed and displayed automatically by a computer print, take the mean registration; vision using automatic perimetry

    (Chongqing, Hong-ASP6000-type) measurements.

     1.2 All surgical operations by a physician with the completion of peribulbar anesthesia. The top of the limbus, after 1? Mm president of 6? Mm scleral tunnel incision in the corner of puncture into the anterior chamber, anterior chamber injection of viscoelastic agents. Under direct vision with viscoelastic injection needle along the angle down slowly into the viscoelastic agent, a continuous injection of addition to the top of the 270 ? angle than would be apparent iris root

    pressure to subside, and use the iris, under gentle pressure bulge Restorer to separate the root of the iris adhesion angle. Followed by continuous curvilinear capsulorhexis, the water separating nuclear and cortex, the nuclear suspension in

    the anterior chamber, his hands France birth to a child of nuclear or nuclear fish out key ring after implantation chamber 5.5? Mm diameter PMMA intraocular lens in the capsular bag. Surgery goes well, without intraoperative posterior

    capsule rupture. There are four cases when the anterior chamber angle in the separation of bleeding, hemostasis after injection of viscoelastic agents.

     3 Discussion

     Acute angle-closure glaucoma with cataract, lens opacity will occur when the expansion of the existing shallow anterior chamber of the eye would increase the shallow anterior chamber, close the angle, causing acute closure attack, simple lens extraction with intraocular lens implantation of intraocular pressure can be effectively controlled . But only

    in the onset time than long, anterior chamber angle has been undergoing extensive adhesions were taken only cataract extraction combined with trabeculectomy, mostly for two incisions, greater intraoperative trauma and postoperative response to heavy, post-operative complications were more

    likely to. We use extracapsular cataract extraction combined goniosynechialysis treatment, removed due to lens opacity caused by decreased visual acuity, intraocular pressure, visual acuity is good and fast, ideal postoperative IOP

    control and avoid a number of operations.

     Acute angle-closure glaucoma in patients with the anatomy of the eye of local variation, is recognized as a major pathogenic factors of this disease. This anatomic variation has a genetic predisposition, including a shorter axial length, corneal small, shallow anterior chamber, narrow angle, and the thick lens or a partial position before, so that the pupil margin in close contact with the lens front surface, over the pupil when the aqueous resistance increased posterior chamber pressure is relatively higher than the anterior chamber, pushing the iris forward ectasia, anterior chamber more shallow and narrower angle [1]. Kurimoto et al [2] found by UBM lens iris and lens attached, intraocular lens

    implantation gap between the iris and lens in the lens removed, the anterior chamber depth increased 1.37 times and 1.57 times the angle opening widened. Lens extraction can eliminate a potential cause pupillary block can lead to acute PACG attack factor.

     After the acute PACG attack, both peripheral iridectomy is OK to lift pupillary block, you can also sustained varying degrees of peripheral anterior synechia of iris or angle-

    closure. Gonioscopy estimate the adhesion range. When the peripheral anterior synechia of the iris caused by angle closure Chaoguo 180 ? when the intraocular pressure; Chaoguo 270 ? when the intraocular pressure lowering drug therapy is usually ineffective, need for additional surgery. Goniosynechialysis (goniosynechi alysis, GSL) is the

    peripheral anterior synechia of iris from the angle of separation, restore trabecular features, for the peripheral anterior synechia of iris not more than 1 year of suffering from eye, intraocular pressure control rate of 80 %; for the

    previous line of filtration surgery, or other ocular conjunctival surgery equally effective [3,4]. For the intraocular pressure control in acute angle-closure glaucoma

    OK lens extraction combined with GSL can achieve better efficacy, Tanihara et al [3] reported that lens extraction

    combined with goniosynechialysis surgical treatment of 5-year

    success rate (82.6%) are simple GSL ( 37.6%) of 2 times. Past

    had phacoemulsification plus intraocular lens implantation in the treatment of acute PACG reported [4 6].

     Teekhasaenee, etc. [4] with phacoemulsification and intraocular lens implantation GSL treatment of 42 patients with 52 acute PACG attack less than 6 months continued to have chronic PACG, after 47 (90.4%) without lowering intraocular pressure intraocular pressure drugs "20 ? mmHg, peripheral anterior synechia of iris an average 31% decrease from preoperative to 6%, non-one cases of decreased vision. We have acute angle-closure glaucoma with extracapsular cataract extraction and intraocular lens implantation

    goniosynechialysis achieve better effect. But the follow-up

    time is short, long-term effect of surgery requires further observation.
