Abstract

Back ground/aims To determine whether parapapillary choroidal microvasculature (PPCMv) density, measured by optical coherence tomography angiography, differed between acute primary angle-closure (APAC), primary open-angle glaucoma (POAG) and controls. Methods This is a prospective, cross-sectional, observational study. Data from 149 eyes from two academic referral centres were analysed. Automated PPCMv density was calculated in inner and outer annuli around the optic nerve region in addition to the peripapillary superficial vasculature, using customised software. A generalised estimating equation was used to compare vessel densities among groups, adjusted for confounders. Results Data from 40 eyes with APAC, 65 eyes with POAG and 44 eyes in healthy controls were gathered and analysed. Global radial peripapillary capillary densities were reduced in eyes with APAC and POAG compared with controls (p=0.027 and 0.136, respectively). Mean outer annular PPCMv density in the POAG group was lower vs the APAC group by 3.6% (95% CI 0.6% to 6.5%) (p=0.018) in the multivariable model adjusted for confounders. The mean difference in inner and outer superior PPCMv between the POAG and APAC groups was 5.9% and 4.4% (95% CI 1.9% to 9.9% and 1.0% to 7.7%, respectively; both p<0.010). Furthermore, POAG and APAC groups both had significantly lower PPCMv compared with controls (both, p<0.001). Conclusions While superficial peripapillary vessels were affected to similar degrees in POAG and APAC, PPCMv drop-out was greater with POAG versus APAC, suggesting that choroidal vessel density may be affected to a lesser extent following an acute increase in intraocular pressure before glaucoma develops.

All glaucoma patients who underwent drainage device implantations were retrospectively reviewed from medical records and divided into three groups: stent group, ligature group, and combined group. The primary outcome was post-operative intraocular pressure (IOP) changes and BCVA (logMAR) change. The secondary outcome is treatment failure. Repeated measurements with mixed models and multi-level parametric survival model stratified by propensity score and eye side were used to compare the primary and secondary outcomes between stent group and ligature group.Main Outcome Measures: Treatment failure between two groups.Results: A total of 163 patients with a mean age of 57.11 ± 19.04 years, implanted with Baerveldt tube, were eligible. There were no significant differences between stent and ligature groups in terms of post-operative IOP changes [mean difference with 95% confidence interval = 0.53 (− 0.49, +1.55) vs − 0.02 (− 0.84, +0.81); P = 0.411] and post-operative BCVA (logMAR) change (0.02 (− 0.13, +0.18) vs – 0.05 (− 0.18, +0.07); P = 0.465). The hazard ratio and 95% confidence interval of treatment failure in ligature group were 2.57 (0.72– 9.19) compared with the stent group.Conclusion: This study suggests a trend toward a better result in the stent group compared with the ligature group. Further research with a larger sample size and randomized control trial is warranted.Keywords: glaucoma drainage device, tube shunt, glaucoma surgery, Baerveldt glaucoma implantation

The patient had a history of coconut hit into his left eye which resulted in traumatic anterior lens subluxation, for which he had undergone phacoemulsification and scleral-fixated intraocular lens implantation in the left eye. Prior scleral fixation procedure, anterior vitrectomy was not performed. Clinical examination showed mushroom-shaped vitreous in the anterior chamber with absolute pupillary block, which had resulted in acute angle closure. Thus, topical and oral antiglaucoma medications were administered to achieve normal intraocular pressure in the left eye, followed by laser peripheral iridotomy in that eye. The anterior chamber depth was successfully increased. Limited anterior vitrectomy by a pars plana approach was performed to prevent recurrent angle closure. The patient’s vision improved and his intraocular pressure remained controlled without any antiglaucoma medication.Conclusion: Vitreous block can occur in patients with pseudophakia, especially in the presence of a ruptured posterior capsule. Cautious intraoperative anterior vitrectomy and surgical iridectomy are warranted. General anesthesia may contribute to the onset of vitreous block in susceptible patients.Keywords: acute angle closure, pseudophakic angle closure, vitreous block, ultrasound biomicroscopy, anterior segment optical coherence tomography

Abstract

Purpose The aim of this study was to report a case series of Brown–McLean syndrome (BMS). Methods The charts of 28 patients with BMS at Ramathibodi and Rutnin Hospital from 1981 to 2015 were reviewed. Results BMS is a rare condition with corneal edema involving the peripheral cornea with orange-brown pigment deposition underlying the edematous area. The edema typically starts inferiorly and advances circumferentially to superior cornea. Central cornea remains clear in most patients. We report 28 patients with BMS that occurred either spontaneously or after various intraocular procedures. Ultrasound biomicroscopy was performed to demonstrate the iridocorneal relationship. Conclusion Iridocorneal relationship from the ultrasound biomicroscopy study in four patients did not support previous hypothesis about the role of iridodonesis impact on corneal endothelium. Patients with BMS can rarely progress to corneal decompensation; however, they should be periodically monitored and made aware of early clinical signs of their complications.

Abstract

Sira Arunmongkol, Yanin Suwan, Wasu Supakontanasan, Suthaphat Nilphatanakorn, Chaiwat Teekhasaenee Department of Ophthalmology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand Introduction: We report a rare case of unexpected gross hyphema in the right eye (OD) and eight-ball hyphema in the left eye (OS) from a bilateral laser iridotomy in an acute primary angle-closure patient. We also demonstrated the effectiveness of the inferior full-thickness trabeculectomy with daily intracameral air injection as an alternative treatment in eight-ball hyphema. Case report: An 81-year-old Thai female presented with gross hyphema grade II OD and eight-ball hyphema with blood-stained cornea OS after laser iridotomy. The patient was scheduled for surgery and the preoperative blood test showed bicytopenia. We performed anterior chamber washout OD and an inferior full-thickness trabeculectomy with daily intracameral air injection OS. The hyphema completely resolved on the following day OD and 3 days after surgery OS. The inferior bleb OS did not raise with digital pressure and became nonfunctional in 7 days. No recurrent hyphema was found in both eyes (OU) during 6 months of follow-up. This patient was ultimately diagnosed with hypocellular myelodysplastic syndrome (MDS). Conclusion: Gross hyphema after laser iridotomy can be seen in patients with hypocellular MDS. The inferior full-thickness trabeculectomy is an alternative surgical procedure for an eight-ball hyphema.

Abstract

Exfoliation syndrome (XFS) is the most common known risk factor for secondary glaucoma and a major cause of blindness worldwide. Variants in two genes, LOXL1 and CACNA1A, have previously been associated with XFS. To further elucidate the genetic basis of XFS, we collected a global sample of XFS cases to refine the association at LOXL1, which previously showed inconsistent results across populations, and to identify new variants associated with XFS. We identified a rare protective allele at LOXL1 (p.Phe407, odds ratio (OR) = 25, P = 2.9 × 10−14) through deep resequencing of XFS cases and controls from nine countries. A genome-wide association study (GWAS) of XFS cases and controls from 24 countries followed by replication in 18 countries identified seven genome-wide significant loci (P < 5 × 10−8). We identified association signals at 13q12 (POMP), 11q23.3 (TMEM136), 6p21 (AGPAT1), 3p24 (RBMS3) and 5q23 (near SEMA6A). These findings provide biological insights into the pathology of XFS and highlight a potential role for naturally occurring rare LOXL1 variants in disease biology.

Abstract

Yanin Suwan, Chaiwat Teekhasaenee, Kaevalin Lekhanont, Wasu Supakontanasan Department of Ophthalmology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand Purpose: The aim of this study was to report a case series of Brown–McLean syndrome (BMS).Methods: The charts of 28 patients with BMS at Ramathibodi and Rutnin Hospital from 1981 to 2015 were reviewed.Results: BMS is a rare condition with corneal edema involving the peripheral cornea with orange-brown pigment deposition underlying the edematous area. The edema typically starts inferiorly and advances circumferentially to superior cornea. Central cornea remains clear in most patients. We report 28 patients with BMS that occurred either spontaneously or after various intraocular procedures. Ultrasound biomicroscopy was performed to demonstrate the iridocorneal relationship.Conclusion: Iridocorneal relationship from the ultrasound biomicroscopy study in four patients did not support previous hypothesis about the role of iridodonesis impact on corneal endothelium. Patients with BMS can rarely progress to corneal decompensation; however, they should be periodically monitored and made aware of early clinical signs of their complications. Keywords: Brown–McLean syndrome, peripheral corneal edema, marginal corneal edema, corneal decompensation

Abstract

Background: To evaluate the mechanisms of acute angle closure (AAC) other than the pupillary block using ultrasound biomicroscopy. Design: Retrospective chart review. Participants: All patients who were diagnosed with AAC in Ramathibodi Hospital, Bangkok, Thailand, between June 2011 and February 2015 were enrolled. Methods: Seventy-two patients who were diagnosed with AAC underwent a detailed ocular examination. The diagnosed mechanism of AAC was confirmed by UBM and ocular biometry. Main Outcome Measures: Primary mechanism responsible for acute angle closure. Results: In 72 patients, the mean age was 62.33 ± 10.4 years, 18 (25%) patients were male and 54 (75%) patients were female. The primary mechanism of AAC was iridolenticular wrapping (crowded-angle (CR) plus anterior lens subluxation (LS)) in 49 eyes (68.1%), pupillary block (PB) in 17 (23.6%) eyes, and plateau iris (PL) in 6 (8.3%) eyes. Thirty (41.7%) out of 72 eyes without previous iridotomy before UBM examination were analyzed. The most common primary mechanism in this group was iridolenticular wrapping (20 eyes, 66.7%). There were seven (23.3%) eyes that had a pupillary block, and only three (10.0%) eyes had plateau iris syndrome as the primary mechanism of AAC. There was a single mechanism in 14 (46.7%) eyes, and there were combined mechanisms in 16 (53.3%) eyes. Conclusions: The most common mechanism contributing to AAC development in this Thai population was iridolenticular wrapping. From this study, we suggest that iridolenticular wrapping was the most common hidden mechanism beyond pupillary block among Thai patients. [ABSTRACT FROM AUTHOR]

Abstract

Background: Report of three patients with pseudophakic angle-closure from a Soemmering ring. Three mechanisms of the Soemmering ring induced pseudophakic angle-closure in three patients were demonstrated by meticulous anterior segment examination and ultrasound biomicroscopic (UBM) analysis.Case Presentation: In the first case, the Soemmering-capsule-IOL complex caused relative pupillary block similar to a phakic eye and was successfully treated with laser iridotomy alone. In the second case, an enlarged Soemmering ring provided posterior iris support in apposition to the anterior chamber angle. We performed a laser capsulotomy through the iridotomised hole. The last, a protruding Soemmering content causing absolute pupillary block became resolved after laser iridotomy and total Soemmering ring content removal.Conclusion: Angle-closure in pseudophakic eyes is uncommon. Several causes have been reported in the literatures including Soemmering ring. This is the first report on three different mechanisms of Soemmering ring related angle-closure in pseudophakic eyes. Ultrasound biomicroscopic analysis plays a crucial role as a diagnostic tool. [ABSTRACT FROM AUTHOR]

Abstract

International audience; Exfoliation syndrome (XFS) is the commonest known risk factor for secondary glaucoma and a significant cause of blindness worldwide. Variants in two genes, LOXL1 and CACNA1A have been previously associated with XFS. To further elucidate the genetic basis of XFS, we collected a global sample of XFS cases to refine the association at LOXL1, which previously showed inconsistent results between populations,and to identify new variants associated with XFS. We identified a rare, protective allele at LOXL1 (p.407Phe, OR= 25, P=2.9 x 10-14) through deep resequencing of XFS cases and controls from 9 countries. This variant results in increased cellular adhesion strength compared to the wild-type (p.407Tyr) allele. A genome-wide association study (GWAS) of XFS cases and controls from 24 countries followed by replication in 18 countries identified seven genome-wide significant loci (P < 5 x 10-8). Index variants at the new loci map to chromosomes 13q12 (POMP), 11q23.3 (TMEM136), 6p21 (AGPAT1), 3p24 (RBMS3) and 5q23 (near SEMA6A). These findings provide biological insights into the pathology of XFS, and highlight a potential role for naturally occurring rare LOXL1 variants in disease biology.
