Outcome of trabeculectomy with intraoperative mitomycin C for uveitic glaucoma

BACKGROUND: The purpose of this study was to compare the outcomes of mitomycin C (MMC)-augmented trabeculectomy in glaucoma patients with uveitis to those without uveitis but with other high-risk characteristics. METHODS: A retrospective comparative cohort analysis consisting of 51 eyes of 51 patients (21 uveitic patients and 30 nonuveitic patients) was performed. Two outcome classifications were analyzed: absolute success (intraocular pressure [IOP]相似文献   

Comparison of phacotrabeculectomy and sequential surgery in the treatment of chronic angle-closure glaucoma coexisted with cataract

AIM: To compare the safety and effectiveness of phacotrabeculectomy versus sequential surgery in chronic angle-closure glaucoma (CACG) with coexisting cataract. METHODS: One hundred and sixty-two CACG patients (162 eyes) were retrospectively analyzed. Of them, 87 patients (87 eyes) in group A had underwent phacotrabeculectomy with intraocular lens (IOL) implantation, and 75 patients (75 eyes) in group B had underwent sequential surgery with IOL implanted. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), complications and anterior chamber angle (ACA) were measured. RESULTS: Demographic characteristics of the two groups were similar. A mean follow-up period was 15±6mo (range 13 to 24mo), a mean IOP of 16.61±6.43 mm Hg in group A and 15.80±5.35 mm Hg in group B (P=0.84) at the last follow up. The Kaplan-Meier analysis revealed that the cumulative probability of success in both groups was similar (P=0.61). Anterior uveitis and hypotony were the most common complications in group A, whereas group B experienced shallow anterior chamber with trabeculectomy. With the exception of anterior uveitis, no complications occurred to 11 trabeculectomized eyes. All postoperative measurements of anterior chamber showed statistically significant differences in each group according to the preoperative data (P<0.05). However, fewer changes occurred in group B than in group A. CONCLUSION: Phacotrabeculectomy and sequential surgery exhibit similar IOP reduction, visual recovery, and complications when treating CACG patients with cataract. However, for a wider ACA, phacotrabeculectomy has demonstrated higher effectiveness than sequential surgery.     

Foldable acrylic versus rigid polymethylmethacrylate intraocular lens in combined phacoemulsification and trabeculectomy

BACKGROUND: Combined trabeculectomy and phacoemulsification is a widely accepted option in treating patients with glaucoma who also have cataracts. Implantation of a foldable intraocular lens (IOL) in cataract surgery has several theoretical advantages.We performed a study to determine the results of combined phacoemulsification and trabeculectomy with mitomycin C and implantation of either a foldable acrylic or rigid polymethylmethacrylate (PMMA) IOL. METHODS: Review of the charts of 58 consecutive patients (60 eyes) who underwent combined phacotrabeculectomy for concomitant cataract and glaucoma at a university-affiliated hospital in Montreal between September 2001 and December 2002. Forty-one eyes received a foldable acrylic lens (3.2-mm-wide incision), and 19 eyes received a rigid PMMA lens (5.2-mm-wide incision). Outcome measures included visual acuity, intraocular pressure (IOP) and postoperative complications. The results in the two groups were compared. RESULTS: There were no differences in baseline characteristics between the two groups. Earlier recovery of visual acuity was noted in the foldable IOL group than in the rigid IOL group (p = 0.013 for the difference at day 7). IOP control was similar in the two groups, as was the incidence of IOP spikes in the early postoperative period. INTERPRETATION: The results suggest that combined phacotrabeculectomy with mitomycin C using a foldable acrylic IOL allows for good postoperative IOP control and earlier visual recovery than the same procedure with insertion of a rigid PMMA lens.     

Management of uveitic glaucoma with Ahmed glaucoma valve implantation

OBJECTIVE: To evaluate the safety and efficacy of Ahmed glaucoma valve implantation for the management of glaucoma associated with chronic uveitis. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Nineteen patients (21 eyes) with chronic uveitis underwent Ahmed glaucoma valve implantation for uncontrolled glaucoma between 1995 and 1998. INTERVENTION: All patients had their uveitis controlled before surgery via immunomodulatory therapy. Ahmed glaucoma valve implantation was performed. Immunosuppression was continued in the early postoperative period for strict control of inflammation. MAIN OUTCOME MEASURES: Control of intraocular pressure (IOP). A secondary outcome measure was the number of antiglaucoma medications required to achieve the desired IOP. Visual acuity and complications associated with the surgery were monitored. RESULTS: The postoperative follow-up averaged 24.5 months. At the most recent visit, all 21 eyes had IOPs between 5 and 18 mmHg. The average pressure reduction after Ahmed glaucoma valve implantation was 23.7 mmHg. The average number of antiglaucoma medicines required to achieve the desired IOP was reduced from 3.5 before surgery to 0.6 after surgery. No eye lost even a single line of Snellen acuity at the most recent postoperative visit. Two eyes developed hypotony in the course of follow-up. One resolved without specific intervention, and the other eye required two autologous blood injections and tube ligature to correct the hypotony. One eye underwent Ahmed glaucoma valve replacement for abrupt valve failure. Two eyes underwent penetrating keratoplasty for reasons believed to be unrelated to the glaucoma surgery. Kaplan-Meier life-table analysis showed a cumulative probability of success after Ahmed glaucoma valve implantation of 94% at 1 year. CONCLUSIONS: Ahmed glaucoma valve implantation can be an effective and safe method in the management of uveitic glaucoma. The authors hypothesize that control of the patients' uveitis, through preoperative and long-term postoperative immunomodulatory therapy, may have contributed to the success rate reported herein.     

Non-penetrating glaucoma surgery augmented with mitomycin C or 5-fluorouracil in eyes at high risk of failure of filtration surgery: long-term results

PURPOSE: To investigate the long-term efficacy and safety of non-penetrating glaucoma surgery (NPGS) augmented with mitomycin C (MMC) or 5-fluorouracil (5FU) in eyes at high risk of failure of glaucoma filtration surgery. METHODS: Prospective study of all eyes, undergoing NPGS with 0.04% MMC (1 to 2 min topical or 0.04 mL subconjunctival injection into the superior fornix) or 5FU (25 mg/mL topically for 5 min). Complete success was an intraocular pressure (IOP)or=20% drop in IOP or a reduction of at least two medications. RESULTS: Twenty-three eyes of 22 patients with a mean follow up of 41.4 months were reviewed. Fifteen eyes had failed trabeculectomy and seven had uveitic glaucoma. Mean preoperative IOP reduced from 25.8+/-7.8 to 15.4+/-4.9 mmHg at final visit, a mean change of 41%. Median number of preoperative medications decreased from 3 to 0 postoperatively. Cumulative probability of success was 100% at 2 years, 94% at 3 years and 85% at 4 years. No patient developed any long-term complications. Complete success was achieved in 11 eyes and qualified success in 10 eyes. Two eyes failed and required further surgery. CONCLUSION: NPGS augmented with small-volume MMC/5FU provides good long-term IOP control in eyes at high risk of failure with a lower incidence of complications compared with augmented trabeculectomy and eliminates the need for postoperative bleb or suture manipulation.     

Long term effect on intraocular pressure of phacotrabeculectomy compared to trabeculectomy

AIM: To compare the long term mean intraocular pressure (IOP) reduction after non-augmented single site phacotrabeculectomy with that after trabeculectomy and to determine the relation between preoperative IOP and IOP reduction. METHODS: A group of 44 consecutive patients with chronic open angle glaucoma who underwent phacotrabeculectomy were matched to a trabeculectomy control group and the results of surgery were compared. Linear regression analysis of preoperative IOP and IOP reduction was undertaken. RESULTS: The mean IOP reduction was significantly less in the phacotrabeculectomy group (6.7 (SD 2.1) mm Hg) than in the trabeculectomy group (11.0 (1.4) mm Hg) (p=0.0017). There was a significant difference in surgical success between the groups. The preoperative IOP was significantly related to the postoperative reduction in IOP in both groups (p<0.001). CONCLUSIONS: In elderly white patients with chronic open angle glaucoma, phacotrabeculectomy is not as effective as trabeculectomy in reducing IOP. In both procedures the magnitude of IOP reduction is proportional to the preoperative IOP.     

Inflammation after implantation of hydrophilic acrylic,hydrophobic acrylic,or silicone intraocular lenses in eyes with cataract and uveitis: comparison to a control group

PURPOSE: To compare the course of inflammation after small-incision cataract surgery with implantation of 1 of 3 types of foldable intraocular lenses (IOLs) in eyes with uveitis. SETTING: Department of Ophthalmology, University of Vienna, Vienna, Austria. METHODS: Seventy-four eyes with uveitis and cataract and 68 control eyes with cataract were prospectively selected to receive a foldable hydrophilic acrylic (Hydroview, Bausch & Lomb), hydrophobic acrylic (AcrySof, Alcon), or silicone (CeeOn 911, Pharmacia) IOL. All surgery was performed by the same surgeon using a standardized protocol: clear corneal incision, capsulorhexis, phacoemulsification, and in-the-bag IOL implantation. Preoperative and postoperative inflammation was evaluated by measuring aqueous flare preoperatively and 1, 3, 7, 28, 90, and 180 days after surgery using the Kowa FC-1000 laser flare-cell meter. All uveitic eyes were in remission for at least 3 months before surgery. RESULTS: In the uveitic eyes, there was no statistically significant difference in the postoperative course of flare and cell among the 3 IOL groups. Six months after surgery in uveitic eyes, flare values reached preoperative levels and the cell count was lower than preoperatively in all 3 IOL groups. Relative flare values were higher in the eyes with uveitis and a CeeOn 911 IOL; however, the difference between this group and the 2 acrylic IOL groups was not significant. CONCLUSIONS: There were no significant differences in inflammation after implantation of foldable IOLs in uveitic eyes. Although absolute flare values and cell counts in eyes with uveitis were higher than in control eyes, primarily because of a damaged blood-aqueous barrier (BAB), BAB recovery was similar between the 2 groups. The changes in the BAB indicate that foldable IOL implantation is safe in uveitic eyes.     

Trabeculectomy with antiproliferative agents in uveitic glaucoma

PURPOSE: To evaluate the outcome of trabeculectomy with antiproliferative agents in patients with uveitic glaucoma METHODS: A retrospective chart review of 44 eyes of 44 patients with uveitic glaucoma who underwent trabeculectomy with mitomycin C or 5-fluorouracil. The authors defined complete success as an intraocular pressure of 21 mm Hg or lower without pressure-lowering medications, qualified success as an intraocular pressure of 21 mm Hg or lower with medications, and failure as an intraocular pressure of more than 21 mm Hg with medications, loss of light perception, or the need for reoperation. RESULTS: The cumulative probability of complete or qualified success was 78% at 1 year and 62% at 2 years. At 2 years, success rates were 39% in males and 71% in females (P = 0.02), 74% in white patients and 55% in black patients (P = 0.58), and 45% in patients with idiopathic uveitis and 74% in patients with sarcoid uveitis (P = 0.17). Sixteen of 31 (51.6%) phakic patients developed new cataracts or had progression of existing cataracts and required cataract extraction. Four of 16 eyes (25%) lost intraocular pressure control and needed repeat trabeculectomy after undergoing cataract surgery. CONCLUSIONS: Patients with uveitic glaucoma can have good outcomes after trabeculectomy with antiproliferative agents. Male gender was the only statistically significant risk factor for trabeculectomy failure. Cataract management in the presence of a filtering bleb poses a treatment dilemma between improvement of visual acuity and loss of intraocular pressure control.     

Efficacy and safety of deep sclerectomy in uveitic glaucoma

Purpose To evaluate the safety and efficacy of deep sclerectomy with implant and mitomycin C in uveitic glaucoma. Design Prospective, noncomparative case study. Patients and methods Nine patients (13 eyes) with uncontrolled uveitic glaucoma underwent deep sclerectomy with implant from 2002 to 2006. All patients had their uveitis controlled before and after surgery with anti-inflammatory therapy. Main outcome measures Control of intraocular pressure. A secondary outcome measure was the number of antiglaucoma medications required to achieve the desired intraocular pressure. Visual acuity and complication associated with the surgery were monitored. Results Mean follow-up was 21 months (range 12–54 months). Intraocular pressure (IOP) was reduced from a mean preoperative value of 28.7 mmHg to a mean postoperative value of 13.85 mmHg (Wilcoxon signed rank test P = 0.005). At the most recent visit, complete success was obtained in 84.6%, qualified success was obtained in 7.7%, and complete failure in 7.7%. Mean number of antiglaucoma medications was reduced from 3.07 to 0.2 (Wilcoxon signed rank test P = 0.001). Neodymium:YAG goniopuncture was performed in two eyes. Postoperative complications included transient hypotony with maculopathy in one eye, shallow choroidal effusions in two eyes, and progression of cataract in four eyes. Conclusion Deep sclerectomy with implant in uveitic glaucoma appeared to be effective in controlling the IOP at short-term follow-up with no serious postoperative side-effects.     

Trabekulektomie bei juveniler idiopathischer Arthritis-assoziierter Uveitis

Background

Secondary uveitic glaucoma in children can only be controlled in many cases by surgery. The aim of this study was to evaluate the outcome of trabeculectomy (TE) with administration of mitomycin C in children with secondary uveitis associated with juvenile idiopathic arthritis (JIA).

Materials and methods

This study was a retrospective chart review of 21 children with uveitic glaucoma who underwent TE with administration of mitomycin C including analysis of complications, further interventions, additional surgical procedures to control intraocular pressure (IOP) and of the success rates after a mean follow-up of 5 years.

Results

Defining success as an IOP ≤?15 mmHg, the surgical success rate after TE was 55?% after 1 year and 38?% after 5 years but 43?% of the children required further IOP controlling operations in the long-term follow-up. An IOP ≤?15 mmHg was observed in 70?% of the children after 1 year and in 62?% after 5 years. In regard to the overall success (with topical antiglaucomatous medication) the success rate increased to 71.4?% after 5 years.

Conclusions

The results show that TE is a suitable surgical procedure to control IOP in secondary uveitic glaucoma of JIA patients. In the long-term follow up additional postoperative adjustments are necessary to control the IOP.     

Phacotrabeculectomy versus two-stage operation: a matched study

BACKGROUND AND OBJECTIVE: To evaluate the efficacy and safety of phacoemulsification and foldable intraocular lens, combined with trabeculectomy (phacotrabeculectomy) in patients with coexisting cataract and glaucoma. PATIENTS AND METHODS: A total of 53 consecutive eyes which underwent phacotrabeculectomy and posterior chamber intraocular lens (PCIOL) were matched and compared with 53 eyes that had trabeculectomy followed by phacoemulsification and posterior chamber intraocular lens (mean interval 3.2 month). The 2 groups were first matched by diagnostic group and subsequently for the closest possible match with other successive variables, including age, gender, race and preoperative glaucoma medications. Mean intraocular pressure (IOP) reduction, visual acuity, antiglaucoma medications, and surgical success as well as complications were compared in both groups. RESULTS: Mean IOP reduction was 14.5+/-4.1 mmHg in the two-stage group compared to 15.1+/-3.9 in the phacotrabeculectomy group at 6 months follow-up (P<0.1) and 13.8+/-3.9 and 14.6+/-3.7 respectively at 1 year (P<0.1).Visual acuity and complications were comparable. CONCLUSION: Phacotrabeculectomy provides IOP control statistically comparable to two-stage surgery with earlier visual rehabilitation.     

Intraocular pressure outcome in primary 5FU phacotrabeculectomies compared with 5FU trabeculectomies

PURPOSE: Combined surgery for glaucoma and cataract may not achieve as low intraocular pressure (IOP) as compared with trabeculectomy alone. The aim of this study was to assess the IOP control of 5-fluorouracil (5FU) phacotrabeculectomies compared with 5-fluorouracil trabeculectomies. METHODS: A retrospective, nonrandomized study of consecutive primary 5FU phacotrabeculectomies and primary 5FU trabeculectomies. The main outcome measures were preoperative and postoperative IOP, number of medications, visual acuity, and complications. RESULTS: Forty-five 5FU phacotrabeculectomies and 47 5FU trabeculectomies were performed with a mean follow-up of 43.1 and 36.6 months, respectively. The absolute success rate as defined as an IOP equal to or less than 16 mm Hg on no glaucoma drops was 62.2% for the phacotrabeculectomy group and 63.8% for the trabeculectomy group. These success rates were not statistically significantly different (log-rank test P = 0.81 for absolute success and P = 0.29 for relative success). The magnitude of the treatment effect was found to be significantly greater in the T group compared with the PT group (a 44.6% reduction in IOP in the T group compared with a 31.2% reduction in the PT group). The phacotrabectomy group underwent significantly more postoperative 5FU injections compared with the trabeculectomy group (P = 0.008). CONCLUSIONS: 5FU phacotrabeculectomy seems to be a safe and effective treatment option in terms of IOP control. Patients with both coexistent glaucoma and cataract could be considered for combined surgery.

Comparison of long-term incidence of posterior capsular opacification between phacoemulsification and phacotrabeculectomy.

PURPOSE: To investigate the long-term incidence of posterior capsular opacification after phacoemulsification compared with phacotrabeculectomy with or without adjunctive subconjunctival mitomycin C. METHODS: This was a retrospectively conducted long-term, observational, case-control study. One hundred eyes of 100 cataract patients who underwent phacoemulsification and posterior chamber intraocular lens implantation and 100 eyes of 100 primary open-angle glaucoma patients with cataract that underwent phacotrabeculectomy and posterior chamber intraocular lens implantation, matched with respect to age, intraocular lens type, prevalence of diabetes mellitus, and length of follow-up. The main outcome measure was the rate of clinically significant posterior capsular opacification as determined by slit-lamp biomicroscopy and necessity to perform neodynium:yttrium aluminum garnet (Nd:YAG) capsulotomy and as calculated by Kaplan-Meier survival analysis. Postoperative visual acuity and maintenance of intraocular pressure control were also measured. RESULTS: There was no significant difference in the rate of posterior capsular opacification requiring Nd:YAG capsulotomy between the phacoemulsification and phacotrabeculectomy groups (P =.77). However, a significant difference in the rate of posterior capsular opacification was found between those patients without diabetes mellitus and those with a preoperative diagnosis of diabetes mellitus (P =.016). Also, survival analysis comparing use of mitomycin C with no use of mitomycin C in the phacotrabeculectomy group showed a higher survival in the mitomycin C subgroup (P =.03). CONCLUSION: There was no significant difference in long-term posterior capsular opacification between phacoemulsification and phacotrabeculectomy in the study population. Intraoperative, adjunctive use of mitomycin C in the phacotrabeculectomy group and the presence of diabetes mellitus in the overall patients were beneficial (protective) factors against posterior capsular opacification.     

Outcome of Baerveldt glaucoma drainage implants for the treatment of uveitic glaucoma

OBJECTIVE: To evaluate the efficacy and safety of Baerveldt glaucoma drainage devices in the management of uveitic glaucoma. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Twenty-four eyes of 24 patients who underwent implantation of Baerveldt glaucoma drainage devices between 1996 and 2000 for the treatment of uveitic glaucoma refractory to medical therapy. INTERVENTION: Implantation of Baerveldt glaucoma drainage device. MAIN OUTCOME MEASURES: Control of intraocular pressure (IOP), number of glaucoma medications needed for adequate IOP control, visual acuity, complications associated with the surgery, and the effect of subsequent surgery on the ability of the device to control IOP. Success was defined as IOP >/=5 and 相似文献   

Prospective evaluation of preoperative factors associated with successful mitomycin C needling of failed filtration blebs

PURPOSE: To study the long-term effectiveness and factors involved in successful needling of failed filtration blebs with mitomycin C (MMC). MATERIALS AND METHODS: We conducted a prospective, nonrandomized comparative trial that included 34 consecutive patients (34 eyes) who underwent mitomycin C needling of a failed filtering bleb after trabeculectomy followed by a 0.01 mL injection of mitomycin C (0.2 mg/ml). The success of the needling revision was defined as absolute if the intraocular pressure (IOP) was < 21 mm Hg without antiglaucoma medications and qualified if the IOP was < 21 mm Hg with antiglaucoma medications. Preoperative and perioperative factors were evaluated for an association with postoperative success using Kaplan-Meier survival analysis. RESULTS: The mean follow-up was 14.2 +/- 9.8 months. The mean preoperative IOP was 25.5 +/- 4.4 mm Hg, which decreased to 11.1, 13.4, 15.8, 16.7, 14.9, 14.1, 13.9, and 13 on postoperative day 1, postoperative week 1, and after 1, 3, 6, 9, 12, and 24 months, respectively (P = 0.001 for each comparison). At the final visit, success was absolute in 15 eyes (44.1%) and qualified in 14 eyes (41.2%). The success rates were 90% and 75% at 1 and 2 years, respectively. The success of the needling procedure was highly correlated with glaucoma filtration surgery performed less than 4 months previously (Kaplan-Meier analysis, log-rank test P = 0.006). CONCLUSIONS: Mitomycin C needling revision appears to have a high long-term success rate. Surgery performed less than 4 months previously contributes to the success of the initial mitomycin C needling procedure.

Risk factors for elevated intraocular pressure in uveitis

PURPOSE: To determine the prevalence of raised intraocular pressure (IOP) in patients with uveitis and to identify risk factors for raised IOP in patients with uveitis. PATIENTS AND METHODS: Consecutive case notes of 257 patients (402 eyes) attending a specialist uveitis clinic during a three-month period were reviewed. Patients with raised IOP were identified and further evaluated. Risk factors for raised IOP were determined. RESULTS: The prevalence of raised IOP in the study eyes was 41.8%. The prevalence of raised IOP requiring treatment was 29.8%. Raised IOP was found in 26.0% of eyes with acute uveitis and 46.1% of eyes with chronic uveitis. This difference was significant (P = 0.002). Similarly the prevalence of raised IOP requiring treatment in acute and chronic uveitis was 15.1% and 33.8%, respectively. This difference was also significant (P = 0.002). Active inflammation was significantly associated with raised IOP (P = 0.031). Steroid usage, increasing age, and number of years since diagnosis were significantly correlated with raised IOP (P = 0.008, P = 0.022, and P = 0.006, respectively); 9.6% of the study eyes developed glaucoma. The majority of these eyes (69.7%) were treated medically. The remainder (30.3%) required both medical and surgical management. CONCLUSION: Raised IOP is significantly more common in patients with chronic intraocular inflammation than those with acute uveitis. Risk factors for elevated IOP that should enable closer monitoring of 'at-risk' eyes have been identified.     

Ahmed glaucoma valve implantation in uveitic glaucoma versus open-angle glaucoma patients

Background: The poor long-term success rate of repeat trabeculectomies in refractory uveitic glaucoma (UG) patients has led to the use of glaucoma drainage devices (GDDs). However, the success and complication rates of GDDs in UG patients utilizing a control group with standard demographic data, design, and surgical technique have never been evaluated. Methods: Fifteen patients (15 eyes) with chronic uveitis and 53 patients (53 eyes) with uncontrolled open-angle glaucoma (OAG) who underwent Ahmed glaucoma valve (AGV) implantation were included in a retrospective, comparative, case-controlled study. Postoperative intraocular pressure (IOP), number of antiglaucoma medications, visual acuity, and complications were compared. Results: There was a significant difference between the UG versus the OAG group with respect to age only (59.3 years vs 68.4 years, p = 0.006). Regression analysis of the postoperative IOP controlled for age and glaucoma type, and preoperative IOP revealed significantly lower IOP in the UG group at 1 month (p = 0.04; 95% confidence interval [CI] -5.9 to 0.15) and 2 months (p = 0.008; 95% CI -6.0 to 0.97). No significant differences were found at 3, 6, 12, 24, and 30 months. The cumulative success rates at 3 to 30 months for the UG and OAG groups were 80% to 66.6% versus 84.9% to 57% (p = 0.713), respectively. The only complication between the 2 groups that was significantly different was tube removal, which occurred more often in the UG group (p = 0.018). Interpretation: AGV implantation is an effective and safe procedure in the management of UG, similar to primary OAG.     

Comparison of 2-year-results of mitomycin C-augmented trabeculectomy with or without cataract extraction in glaucoma patients

PurposeComparison of the 2-year results of phacotrabeculectomy (CET) and trabeculectomy (TE), both augmented with mitomycin C.MethodsThis prospective study enclosed 246 eyes in 246 consecutive patients that had undergone trabeculectomy (n = 85) or phacotrabeculectomy (n = 161, hereof n = 10 phacoretrabeculectomy) augmented by mitomycin C. Endpoints were best corrected visual acuity (BCVA), intraocular pressure (IOP), and number of antiglaucomatous medications at baseline, 3 months, and 2 years postoperatively. Postoperative management involved local steroid application and laser suture lysis according to a standardized protocol.ResultsBoth interventions reduced IOP statistically significant and stable. In the phacotrabeculectomy group BCVA improved from 0.45 ± 0.47 logMAR units preoperatively to 0.28 ± 0.54 logMAR units at 2 years (p < 0.001) and remained unchanged in the trabeculectomy group. After 2 years IOP reduced from 22.5 ± 7.2 mm Hg preoperatively to 11.5 ± 3.1 mm Hg in the TE group and from 20.0 ± 5.4 mm Hg to 12.5 ± 4.8 mm Hg in the CET group (both p > 0.05). The mean number of antiglaucomatous medications was significantly reduced from 2 ± 1 in both groups to 0.3 in the trabeculectomy group and to 0.4 in the phacotrabeculectomy group. With this standardized surgical procedure and postoperative protocol, there was no need for local postoperative antimetabolites. No Tenon's capsule cysts developed. In the subgroup of patients with phacoretrabeculectomy BCVA and IOP improvements were comparable to the phacotrabeculectomy group outcomes.ConclusionsPhacotrabeculectomy is comparably as effective as trabeculectomy alone in reducing IOP and the need for antiglaucomatous medication over a time interval of 2 years. We found indications that this favourable therapeutic effect is also true for patients needing phacoretrabeculectomy treatment.
