Anterior chamber parameters measured by the Pentacam CES after uneventful phacoemulsification in normotensive eyes

Purpose: We set out to quantify changes in the anterior chamber volume (ACV), anterior chamber depth (ACD) and anterior chamber angle (ACA) measurements obtained by the Pentacam rotating Scheimpflug camera following uneventful phacoemulsification surgery in normotensive eyes with open iridocorneal angles. Methods: We enrolled 44 eyes of 44 consecutive patients undergoing cataract extraction in this prospective study. Patients with a history of glaucoma, angle‐closure glaucoma or any other concurrent ocular disease were excluded. A detailed eye examination including intraocular pressure (IOP) measurement was performed and ACV, ACD and inferior, superior, temporal and nasal ACA measurements were obtained in each patient eye using the Pentacam Comprehensive Eye Scanner (Pentacam CES) before and 3 months after phacoemulsification and intraocular lens (IOL) implantation with temporal clear corneal incision. Data were compared using paired t‐test and one‐way anova . Results: Mean preoperative ACV, ACD, ACA and IOP measurements were 164.7 ± 49.8 mm³, 3.0 ± 0.8 mm, 35.7 ± 10.2 ° and 15.8 ± 3.7 mmHg, respectively. Three months postoperatively, mean ACV, ACD, ACA and IOP measurements were 200.9 ± 33.3 mm³, 3.9 ± 0.9 mm, 41.5 ± 6.5 ° and 13.2 ± 3.9 mmHg, respectively. Postoperative mean ACV, ACD and ACA values in all four quadrants were significantly increased (p < 0.0001, p < 0.0001, p < 0.0001, respectively), whereas IOP was significantly reduced (p < 0.0001). Conclusions: The Pentacam CES allowed very easy, fast, automatic and non‐contact quantification of the anterior chamber parameters pre‐ and postoperatively in all patient eyes. Measurements obtained confirm that in normotensive eyes with open iridocorneal angles, the ACV and ACD increase and the ACA widens in all quadrants 3 months after uneventful phacoemulsification and IOL implantation. These changes are accompanied by a significant fall in IOP in the short term.

目的:评价白内障超声乳化联合人工晶状体(intraocular lens,IOL)植入术治疗眼压控制的急性闭角型青光眼和慢性闭角型青光眼患者的疗效及安全性。方法:将45例60眼白内障眼压控制的急性闭角型青光眼和慢性闭角型青光眼随机分为两组,一组采用白内障超声乳化联合IOL植入术,一组采用激光虹膜切开术(laser iridotomy,LI)。比较两组眼内压、抗青光眼药物使用数目、并发症、前房内皮细胞计数的差别。结果:IOL组中,随访6mo后的眼内压由术前的14.82±4.23mmHg下降到10.94±1.24mmHg,而LI组的眼内压并无明显变化(15.34±4.13mmHgvs14.68±4.77mmHg),采用重复测量资料的方差分析显示两组的眼内压变化有显著统计学差异(F=36.452,P<0.01)。IOL组6mo后基本未采用抗青光眼药物,而LI组使用抗青光眼药物个数为0.24±0.41个(P<0.05)。两组在并发症及前房内皮细胞计数方面无统计学差异(P>0.05)。结论:白内障超声乳化联合IOL植入可有效降低眼压控制的急性闭角型青光眼和慢性闭角型青光眼的眼内压水平,该治疗方法安全有效,是这类患者首选的治疗方法之一。     

Effect of nintedanib thermo-sensitive hydrogel on neovascularization in alkali burn rat model

AIM: To investigate the effects of nintedanib thermo-sensitive hydrogel (NTH) on neovascularization and related markers in corneal alkali burns of Wistar rats. METHODS: NTH was prepared by grinding, and its phase-transition temperature was determined. Thirty specific-pathogen-free Wistar rats served as a model of corneal alkali burn in the right eye were randomly divided into 3 groups (n=10, each): model group treated with 0.9% saline once a day, NTH group with 0.2% nintedanib b.i.d, and dexamethasone group with dexamethasone ointment once a day. The left eye of rats served as the controls. The corneal transparency was observed under a slit-lamp microscope, and the area of neovascularization was calculated. On day 7, the rats were sacrificed, and the cornea was removed and embedded with paraffin, then stained with hematoxylin-eosin, and the expression of vascular endothelial growth factor receptor 2 (VEGFR-2) and CD31 in the corneal tissues of each group was detected by immunofluorescence. RESULTS: The phase-transition temperature of nintedanib obtained by grinding was 37℃ after adding artificial tears. The results of the alkali burn model indicated that the growth rate of neovascularization in the NTH group was slower than that in the model group, and the neovascularization area was significantly smaller than that in the model group (P<0.05). Moreover, CD31 and VEGFR-2 expression levels in the NTH group were significantly lower than those in the model group. CONCLUSION: NTH becomes colloidal at body temperature, which is beneficial for releasing the drug slowly and can significantly inhibit the neovascularization of corneal induced by alkali burn in rats.     

Combination of cataract surgery with intravitreal injection of dexamethasone intravitreal implant (Ozurdex) for uveitis-induced cataract

AIM: To evaluate the long-term results of patients with chronic uveitis-induced cataract by phacoemulsification with IOL implantation and intravitreal injection of dexamethasone (DEX) intravitreal implant (Ozurdex). METHODS: The study included 32 eyes of 26 patients treated with DEX implant due to chronic uveitis-induced cataract and followed up for at least a year. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), anterior chamber reaction, central macular thickness (CMT), intraoperative and postoperative complications and uveitis recurrence were analyzed retrospectively. RESULTS: A successful surgery was performed in all patients. The average follow-up period was 12mo. The female/male ratio was 13/13. Mean age was 45.65±3.83y (range 26 to 65y). Etiologically, rheumatic arthritis occurred in 6 patients (18.75%), ankylosing spondylitis in 4 (12.50%), HLA-B27 associated uveitis in 3 (9.38%), Vogt-Koyanagi-Harada-associated uveitis in 4 (12.50%) , Behcet''s disease in 2 (6.25%), and 7 (21.88%) suffered from unknown diseases. All 32 eyes had varying degrees of improvement at 12mo after surgery, with 2 eyes showing BCVA of 0.1 or below (6.25%), 6 having 0.1-0.5 (18.75%), 18 of 0.5-1.0 (56.25%), and 6 of 1.0 or above (18.75%). No cases with increased IOP were observed. The values of mean CMT was increased at day 1, decreased at 1, 3mo after surgery and increased at 6, 12mo after surgery. No severe uveitis reactions, such as fibrinous exudates in the anterior chamber and exudative membrane formation on the anterior surface of the IOL, were observed after surgery. CONCLUSION: The present studies show that intravitreal injection of Ozudex during cataract operation can provide a new option for the clinical treatment of uveitis-induced cataract.

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.     

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.

青光眼白内障联合术植入不同材料人工晶状体效果评价

目的比较青光眼白内障联合术中植入不同材料人工晶状体（IOL）的临床效果。方法回顾性分析行青光眼白内障联合术70例（76眼），其中植入PMMA IOL30例（36眼），硅胶IOL23例（23眼），丙烯酸酯折叠IOL17例（17眼）。对治疗效果进行评价，平均随访期限为10．5月。结果3组间术后眼压和最佳矫正视力差异无统计学意义。前房纤维素样渗出物和IOL表面沉积物发生率，硅胶组高于PMMA组和丙烯酸酯组，但差异无统计学意义。后发障发生率，丙烯酸酯组和硅胶组显著低于PMMA组，差异有统计学意义。结论行青光眼白内障联合术植入PMMA，硅胶与丙烯酸酯IOL在降眼压和提高视力方面具有相似的效果。但硅胶IOL的前房纤维素样渗出物及IOL表面沉积物发生率高于PMMA和丙烯酸酯IOL。丙烯酸酯和硅胶IOL的后发障发生率低于PMMA IOL。     

Phacotrabeculectomy with mitomycin C in patients with uveitis

PURPOSE: To evaluate the safety and efficacy of combined phacoemulsification, intraocular lens implantation, and trabeculectomy with mitomycin C for the management of uveitic complications. DESIGN: Retrospective case-control study. METHODS: We conducted a retrospective review of the records of 23 consecutive eyes with chronic noninfectious uveitis (uveitic group) and 43 nonuveitic eyes (control group) that had received primary phacotrabeculectomy. Mitomycin C was used in all the uveitic eyes. Considering the high preoperative intraocular pressure (IOP) of the uveitic group, nonuveitic eyes that had a preoperative IOP of >or=20 mm Hg or that had been given two or more medications were included in the control group. All patients were followed for at least one year. The main outcome measures were postoperative vision, IOP control, complications, and acute uveitis relapse rates. RESULTS: Visual outcome of the uveitic group was similar to the control group. In the uveitic group, the success rate of IOP control (91.3% at one year, 84.8% at two years) was favorable but was significantly lower than in the control group (P = .0423). Complications were comparable between the groups. Primary surgical failure in the uveitic group was associated with the postoperative acute uveitis attack. In the uveitic group, the acute uveitis attack rate showed no change after surgery (P = .283). CONCLUSION: With adequate inflammation suppression, phacotrabeculectomy with mitomycin C is an effective and safe therapeutic option for the management of secondary cataract and glaucoma in uveitic eyes. A lower surgical success rate of the uveitic group might be attributable to the postoperative inflammation recurrence.

Cataract surgery in exudative uveitis: effectiveness of total lens removal, anterior vitrectomy, and scleral fixation of PC IOLs

PURPOSE: Cataract surgery in exudative uveitis is often followed by severe complications (pupillary seclusion/occlusion, dense posterior capsule/anterior vitreous opacification, cystoid macular edema following repeat YAG laser procedures) which often drastically limit functional recovery. Total removal of cataract, anterior vitrectomy, and scleral fixation of a posterior chamber (PC) intraocular lens (IOL) has been tried as a surgical alternative, searching for lessened postsurgical complications and a better outcome. METHODS: Group A was a cohort of 12 patients with cataract after exudative (mostly sarcoidosis and Vogt-Koyanagi-Harada) uveitis, subjected to intracapsular cataract extraction, anterior vitrectomy, and scleral fixation of PC IOLs. Group B was the control group, including 12 patients with a similar clinical condition subjected to phacoemulsification or extracapsular cataract extraction plus in the- bag or in-the-sulcus IOL implantation. Follow-up time for both groups was at least 7 years. RESULTS: Postoperative inflammatory signs were substantially less in Group A patients, from 2 days up to >7 years postsurgery. Group A patients showed no cells/exudates adhering to the IOL surfaces, no synechiae, minimal (as compared to Group B) vitreous opacifications, and significantly higher visual acuity (p=0.024 at the seventh year control). Group A patients reported less frequent relapses of uveitis postsurgery, but the relevant clinical data did not allow statistical evaluations. CONCLUSIONS: Total removal of cataract in highly exudative uveitic eyes, plus anterior vitrectomy and scleral fixation of PC IOLs, although technically a more demanding surgical procedure, proved to be safe and more effective than classical procedures.     

Longterm results of one-site phacotrabeculectomy

PURPOSE: To evaluate results of one-site phacotrabeculectomy and intraocular lens (IOL) implantation. METHODS: A retrospective study of a consecutive series of 62 eyes with cataract and glaucoma, which underwent primary one-site phacotrabeculectomy with IOL implantation. Mean follow-up time was 28 +/- 12.3 months (range 12-46 months). RESULTS: Preoperative mean intraocular pressure (IOP) (25.1 +/- 8.6 mmHg) dropped significantly, to 16.4 +/- 1.3 mmHg 1 year after surgery (p < 0.01). Mean logMAR best corrected visual acuity (VA) improved significantly from 0.74 +/- 0.49 to 0.22 +/- 0.28 (p < 0.01). The most common complications were fibrinous exudation (10%) and choroidal detachment (6%). In two eyes (3%) we successfully performed scleral flap revision to achieve IOP control. CONCLUSION: One-site combined surgery was a safe and effective procedure with good IOP control and visual rehabilitation.     

Comparison of Artisan iris-claw intraocular lens implantation and posterior chamber intraocular lens sulcus fixation for aphakic eyes

AIM: To compare the efficacy and complications of Artisan iris-claw intraocular lens (IOL) implantation and posterior chamber IOL sulcus fixation for the treatment of aphakic eyes without capsular support after vitrectomy.METHODS:A prospective study of 45 cases was conducted. Forty-five eyes without sufficient lens capsule support following pars plana vitrectomy (PPV) combined lens extraction were divided into two groups. Group A:25 eyes received Artisan iris-claw IOL implantation. Group B:20 eyes received posterior chamber IOL sulcus fixation. The corrected distance visual acuity (CDVA) and intraocular pressure (IOP), corneal endothelial cell loss rate, surgical time and complications were compared between the two groups. Pigment changes of trabecular meshwork and anterior chamber depths were measured at each time point in Artisan group.RESULTS:The mean surgical time of Artisan group was significantly shorter (P<0.05). No statistically significant difference in endothelial cell loss rate was noted between two groups at any time point (P>0.05). CDVA of Artian group was better than that of the sulcus fixation group 1d after surgery (P<0.05) and there was no statistically significant difference 1 and 3mo after surgery (P>0.05). Mean IOP showed no significant differences between groups before and after surgery. The postoperative complications of Artisan group were anterior uveitis, iris depigmentation, pupillary distortion and spontaneous lens dislocation. The complications of sulcus fixation group include choroidal detachment, intraocular haemorrhage, tilt of IOL optic part and retinal detachment.CONCLUSION:Secondary Artisan IOL implantation can be performed less invasively and in a shorter surgical time period with earlier visual recovery after surgery compared to transscleral suturing fixation of an IOL. This technique is an effective and safe procedure. It is a promising option for the treatment of aphakic eyes without capsular support after vitrectomy.
