“…An epidemiological study showed that the prevalence of primary angle-closure glaucoma was much higher in Asia, especially in China, than in other areas. [15][16][17][18] The aim of malignant glaucoma therapy is to relieve the ciliolenticular block, disrupt the misdirection of aqueous humor and to restore normal aqueous flow. 19 Drug therapy induces a posterior movement of the lens-iris diaphragm, reduces the production of aqueous humor, and dehydrates the vitreous volume.…”

Objective The objective of this study was to evaluate the clinical effects of modified partial pars plana vitrectomy together with phacoemulsification, intraocular lens (IOL) implantation, posterior capsulectomy, and zonulohyaloidectomy for patients with malignant glaucoma after trabeculectomy or cataract surgery. Design Retrospective, cohort study. Participants Thirty consecutive patients (30 eyes) with malignant glaucoma after trabeculectomy surgery or ultrasonic phacoemulsification of cataract between January 2008 and September 2014 were enrolled. Methods A retrospective analysis of 30 eyes with malignant glaucoma after trabeculectomy surgery for angle-closure glaucoma or ultrasonic phacoemulsification of cataract was performed. All patients underwent modified partial pars plana vitrectomy with zonulohyaloidectomy. Phacoemulsification and IOL implantation was performed in 25 patients with no previous cataract surgery. Preoperative and post-operative ocular parameters were recorded in detail. Main outcome measures Clinical features, anterior chamber depth, best-corrected visual acuity, and intraocular pressure (IOP). Results In these 30 patients, 25 had undergone trabeculectomy surgery and 5 had undergone cataract surgery. The mean axial length was 21.3 ± 0.8 mm. After surgery, mean IOP decreased from 34 ± 8.3 mm Hg to 10.5 ± 4.1 mm Hg (Po0.001), and mean anterior chamber depth increased from 0.8 ± 0.4 mm to 2.7 ± 0.3 mm (Po0.001). No severe complications occurred. Conclusions Modified partial pars plana vitrectomy combined with phacoemulsification, IOL implantation, posterior capsulectomy, and zonulohyaloidectomy not only simplifies the process of traditional vitrectomy, but effectively resolves the ciliary block and corrects the misdirection of aqueous humor in malignant glaucoma.

“…There is some consensus among published papers that the scleral spur is more easily identifiable with AS-OCT, although in our experience there was no difficulty with either method. 12,27 This fact could potentially signify better accuracy for OCT measurements when compared with UBM.…”

Purpose To compare the accuracy in measurement of the anterior chamber (AC) angle by anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) in European patients with suspected primary angle closure (PACS), primary angle closure (PAC), or primary angleclosure glaucoma (PACG). Design Cross-sectional study. Methods In all, 55 eyes of 33 consecutive patients presenting with PACS, PAC, or PACG were examined with AS-OCT, followed by UBM. The trabecular-iris angle (TIA) was measured in all four quadrants. The angle-opening distance (AOD) was measured at 500 lm from the scleral spur. The BlandAltman method was used for assessing agreement between the two methods. Results The mean (±SD) superior TIA was 19.3 ± 15.81 in AS-OCT and 15.7 ± 15.01 in UBM (P ¼ 0.50) and inferior TIA was 17.9 ± 12.91 (AS-OCT) and 16.7 ± 14.11 (UBM) (P ¼ 0.71). The superior AOD 500 was 0.17 ± 0.16 mm in UBM and 0.21 ± 0.16 mm in AS-OCT (P ¼ 0.06). BlandAltman analysis showed a mean SD of±9.41 for superior and inferior TIA and a mean SD of ±0.10 mm for superior and inferior AOD 500 .Conclusions This comparative study shows that AS-OCT measurements are significantly correlated with UBM measurements but show poor agreement with each other. We do not believe that AS-OCT can replace UBM for the quantitative assessment of the AC angle.

“…Direct epidemiologic data on prevalence of CAG in Latin America are limited. They range from a general estimation of 5.7% of glaucoma cases (1) to 21.4% in one sample from South Brazil (30) . Unpublished surveys indicate that CAG rates may be high in some native ethnic populations within Latin America.…”

70% of respondents. RESULTS: Fifty participants from 14 countries completed the questionnaire. For the medical treatment of glaucoma, nearly all respondents (98% or greater) confirmed that medical treatment as first-line therapy is preferred to surgery, prostaglandin analogs are the medication of first choice for primary open-angle glaucoma (POAG), longitudinal monitoring of efficacy should include intraocular pressure, structural and functional status, as well as if patients' quality of life is impaired by the high cost of medication. For the diagnosis of glaucoma section, all respondents confirmed that, after initial examination, gonioscopy should be repeated over time, standard automated perimetry is the most important functional examination for diagnosis and monitoring of primary open-angle glaucoma, central corneal thickness is important in assessment of glaucoma, and computerized imaging tests help in clinical evaluation of optic disc. CONCLUSIONS: This survey shows a high level of agreement on most aspects of glaucoma diagnosis and treatment among Latin American glaucoma experts. Areas of disagreement highlight the need for further evidence or education. These findings will be useful for guiding future efforts to optimize glaucoma practice by clinicians in Latin America.]]>
