We performed the prospective study on the clinical result of sutureless phacotrabeculectomy using 3.0mm ~ 6.5mm self-sealing scleral tunnel incision. This study included 9 eyes of 8 patients who have been suffering from chronic angle-closure glaucoma or chronic open-angle glaucoma with coexisting cataract. The mean preoperative intraocular pressure(IOP) was 28.55mmHg and mean postoperative IOP was 15.55mmHg. The IOP maintained below 19mmHg in all cases after 6 months. The number of medications decreased from 1.77 preoperatively to 0.33 postoperatively. No medication needed in 7 eyes postoperatively. The mean preoperative cup-disc ratio was 0.64. Visual acuity improved in 8 eyes and 5 eyes recovered to 20/40 or better. The blebs were visible in 8 cases which shows low diffuse in character in most cases. Postoperative complications were hypotony in 5 cases, hyphema in 1 case, partial posterior capsular rupture in 1 case and posterior capsular opacification in 1 case respectively. This result suggests that sutureless phacotrabeculectomy may be performed as safe and effective combined procedure in the management of coexisting cataract and glaucoma.

Mitomycin C has an inhibitory effect on the proliferation of fibroblasts and it is used as an adjunct to trabeculectomy. To clarify the effects of mitomycin C on trabeculectomy, we ana lysed 95 eyes that received trabeculectomy with mitomycin C and 90 eyes that received trabeculectomy without mitomycin C. There were no significant differences in sex, age, type of glaucoma and preoperative intraocular pressure (IOP) between two groups (p>0.05 respectively). The mean rops at 6 months after surgery and the success rate were not significantly different between two groups (p>0.05). But considering the mean IOP of successful cases, the mitomycin C used group showed the lower postoperative IOP(p<0.05). The rate of complete seccess which had no antiglaucoma medications and 5-fluorouracil administration during the postoperative period was higher in the mitomycin C used group (p<0.05). Postoperative complications, espicially hypotony, were more common in the mitomycin C used patients. Hypotony was more frequent in the patients who received brief exposure of mitomycin C. Most of the hypotony patients had primary open angle glaucoma and lower preoperative IOP. According to the results of our study, mitomycin C should be used in the high risk group patients who are young and have secondary glaucoma or history of failure of filtering procedures, and also in the patients with difficulty of postoperative medical treatment and requiring lower IOP.

PURPOSE: To report a case of ab interno trabeculotomy with Trabectome(R) (NeoMedix Corp., CA, USA) conducted on a refractory primary open angle glaucoma (POAG) patient. CASE SUMMARY: Trabectome(R) has microelectrocautery with simultaneous infusion and aspiration of debris and ablates a segment of trabecular meshwork and the inner wall of Schlemm's canal. The patient, a 54-year-old man had uncontrolled intraocular pressure (IOP) with topical anti-glaucoma medications after trabeculectomy and Ahmed valve implantation for POAG. For the patient, ab interno trabeculotomy with Trabectome(R) was performed. There were no other postoperative complications except for microhyphema immediately after surgery. The IOP was controlled between 14 to 24 mm Hg up to 3 months postoperatively with topical anti-glaucoma medications (Cosopt(R), Alphagan-P(R), Lumigan(R)). CONCLUSIONS: Ab interno trabeculotomy with Trabectome(R) appears to offer a newer method of lowering IOP in POAG than conventional trabeculectomy and glaucoma drainage device surgery.

To report acute onset lens particle glaucoma associated with a spontaneous anterior capsular dehiscence. A 66-year-old man presented with spontaneous anterior lens capsule dehiscence with an acute onset of right eye pain that was associated with white particles in the anterior chamber angle and intraocular pressure (IOP) of 55 mmHg. No trauma or other inflammatory antecedents were reported. A hypermature cataract was observed at slit lamp exam. After medical treatment without IOP control, we performed extracapsular cataract extraction and anterior vitrectomy. Anterior chamber aspirate confirmed the presence of macrophages. The postoperative IOP at one month was 16 mmHg OD without medication. Spontaneous dehiscence of the anterior lens capsule in a patient with a hypermature cataract may release lens cortical material, resulting in lens particle glaucoma. Prompt surgical removal of the lens material usually controls the high IOP, and the need for additional glaucoma surgery is not common.

PURPOSE: To compare the accuracy of intraocular lens (IOL) power calculation formulas in eyes with primary angle closure glaucoma (ACG). METHODS: This retrospective study compared the refractive outcomes of 63 eyes with primary ACG with the results of 93 eyes with normal open angles undergoing uneventful cataract surgery. Anterior segment biometry including anterior chamber depth, axial length, and anterior chamber depth to axial length ratio were compared by the IOL Master. Third generation formulas (Hoffer Q and SRK/T) and a fourth generation formula (Haigis) were used to predict IOL powers in both groups. The predictive accuracy of the formulas was analyzed by comparison of the mean error and the mean absolute error (MAE). RESULTS: In ACG patients, anterior chamber depth and the anterior chamber depth to axial length ratio were smaller than normal controls (all p < 0.05). The MAEs from the ACG group were larger than that from the control group in the Haigis formula. The mean absolute error from the Haigis formula was the largest and the mean absolute error from the Hoffer Q formula was the smallest. CONCLUSIONS: IOL power prediction may be inaccurate in ACG patients. The Haigis formula produced more inaccurate results in ACG patients, and it is more appropriate to use the Hoffer Q formula to predict IOL powers in eyes with primary ACG.

Pseudoexfoliation syndrome is characterized by the presence of gray-white flakes on the pupillary borders and anterior lens capsule, increased trabecular meshwork pigmentation, and association with glaucoma. We describe 3 patients with this syndrome seen at Asan Meidcal Center Department of Ophthalmology in 1989, and we focus on their clinical features and management. We believe that patients with this syndrome are not as rare in Korea as has been thought, judging by scant report of cases in the past.

PURPOSE: To evaluate outcomes and factors associated with surgical failure in patients who underwent combined phacoemulsification and Ahmed glaucoma valve (AGV) implantation. METHODS: This retrospective and longitudinal study enrolled 40 eyes (38 patients) that underwent combined phacoemulsification and AGV implantation. Visual acuity, intraocular pressure (IOP), and number of antiglaucoma medications were evaluated preoperatively and postoperatively. Complete success was defined as a last follow-up IOP of 6 to 21 mmHg without medication, qualified success as an IOP of 6 to 21 mmHg with medication, and failure as an IOP of >21 or <6 mmHg. RESULTS: The mean follow-up period was 18 ± 10 months. Preoperative diagnoses were chronic angle closure glaucoma (35.0%), neovascular glaucoma (22.5%), uveitic glaucoma (17.5%), primary open-angle glaucoma (15.0%), and other (10.0%). IOP decreased from a mean of 30.5 ± 8.7 to 14.5 ± 3.7 mmHg at the last follow-up visit (p < 0.001). Treatment was classified as qualified success in 18 eyes (45%), complete success in 15 (37.5%), and failure in seven (17.5%). Twenty-two eyes (55%) showed improvement in visual acuity. The most common postoperative complication was a transient hypertensive phase (five eyes, 12.5%). Tube-iris touch was associated with surgical failure (hazard ratio, 8.615; p = 0.008). CONCLUSIONS: Combined phacoemulsification and AGV implantation is an effective and safe surgical option for patients with refractory glaucoma and cataract. Postoperative tube-iris touch is an indicator of poor prognosis.

We analyzed the clinical result of trabeculectomy with amniotic membrane transplantation which has antifibrotic and antiinflammatory action in risky glaucoma patients. Subjects were included four eyes of four patients with neovascular glaucoma, one eye of one patient with primary open angle glaucoma and four eyes of three patients with congenital glaucoma. After limbal based scleral flap was made in triangular shape with 5x4 mm sized, amniotic membrane, sized by 6x6 mm with epithelial side up, was placed on the scleral flap and then sutured to medial and lateral portion at 3 mm superior to base of scleral flap base with 10-0 nylon(2 points). The state of bleb, intraocular pressure and complications were observed at postoperative 1st, 3rd, 6th and 9th week. The IOP was reduced from 33.6+/-11.1 mmHg, to 15.5+/-6.5 mmHg at postoperative one week, 17.0+/-8.3 mmHg at three weeks, 16.9+/-8.1 mmHg at six weeks, 17.1+/-6.4 mmHg at nine weeks. 6 eyes(77.7%)had controlled IOP under 21 mmHg without antiglaucomatous agents at last follow up. Avascular blebs were observed throughout postoperative period in all subjects. Postoperative complications were shallow anterior chamber in one eye at 1st week and low intraocular pressue in one eye at 1st, 3rd week, that resolved at six weeks. Trabeculectomy with amniotic membrane transplantation on the scleral flap appeared to be effective as an augment therapy for filtering surgery in risky glaucoma.

PURPOSE: To investigate the efficacy and safety of selective laser trabeculoplasty (SLT) in pregnant and lactating women who have primary open-angle glaucoma and ocular hypertension. METHODS: From January 2006 to August 2006 SLT was performed in fertile female patients with primary open-angle glaucoma and ocular hypertension. Intraocular pressure (IOP) was measured at 1 hour, 1 day, 1 week, 1 month, 3 months, and 6 months after SLT. Anterior chamber reaction and ocular pain were checked on postoperative day 1. Peripheral anterior synechia was examined at postoperative 6 months. Any anti-glaucoma drug was discontinued after SLT procedure, and restarted when needed. RESULTS: 22 patients (40 eyes) of primary open-angle glaucoma (40 eyes) and ocular hypertension (10 eyes) were included. The mean baseline intraocular pressure was 31.6 mmHg. The mean IOP was 15.7 mmHg and the mean number of anti-glaucoma drug was 1.3+/-0.6 preoperatively. There was successful IOP decrease at postoperative 1 day (17.9 mmHg), 1 week (16.3 mmHg), 1 month (17.7 mmHg), 3 months (18.4 mmHg), and 6 months (19.0 mmHg). The mean number of anti-glaucoma drug was 0.43+/-0.7 (p=0.000) postoperatively. There were no significant postoperative complications in the 6-month follow-up period. CONCLUSIONS: SLT seems to be a safe and effective procedure for fertile female patients who need to discontinue or reduce the anti-glaucoma drugs.
