Effect of Multifocal Intraocular Lens on Contrast Sensitivity in Primary Angle-Closure Patients
Objective: To study the effect of multifocal intraocular lens (MIOL) implantation on contrast sensitivity (CS) compared to monofocal intraocular lens (mIOL) in primary angle-closure (PAC) or primary angle-closure glaucoma (PACG) patients.
Materials and Methods: This prospective study included patients with PAC or PACG and visually significant cataract. Phacoemulsification with MIOL or mIOL (patient preference) was performed. Collected data included best-corrected distant visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), and contrast sensitivity (CS) measured at spatial frequency 1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree (CPD) preoperatively, and at 2-6 months postoperatively. Preoperative and postoperative parameters were then compared.
Results: Of the 45 eyes from 35 patients that were enrolled, 33 eyes (15 PAC, 18 PACG) from 26 patients completed the study. Fourteen eyes (11 patients) received diffractive MIOL, and 19 eyes (15 patients) received aspheric mIOL. Preoperative CS was not significantly different between groups. Postoperatively, BCVA, and CS at each spatial frequency were significantly improved in both groups (all p<0.001). Mean postoperative CS at spatial frequency 1.5, 3.0, 6.0, 12.0, and 18.0 CPD was 28.03, 42.63, 44.84, 10.82, and 2.86 in the MIOL group, and 29.55, 49.63, 46.20, 16.83, and 7.09 in the mIOL group, both respectively. Postoperative CS was not significant different between groups at any spatial frequencies. IOP was decreased (p=0.001) and ACD increased (p<0.001) postoperatively in both groups.
Conclusion: No significant difference in visual acuity or contrast sensitivity was observed between MIOL and mIOL after cataract removal in patients with PAC/PACG
Efficacy of Selective Laser Trabeculoplasty in Phakic and Pseudophakic Patients with Open-Angle Glaucoma
Objective: To compare the efficacy of selective laser trabeculoplasty (SLT) in terms of intraocular pressure (IOP)
reduction between phakic and pseudophakic patients with open-angle glaucoma (OAG).
Methods: Phakic and pseudophakic patients with OAG who had IOP ≥15 mmHg treated with ≥2 topical antiglaucoma
medications were enrolled. Pseudophakic eyes with history of complicated phacoemulsification were
excluded. SLT was performed 270 degrees by one surgeon under the same protocol. IOP was measured with
applanation preoperatively and at 1 hour, 1 week, 3 weeks and 3 months postoperatively.
Results: There were 59 eyes (38 phakia and 21 pseudophakia) from 38 patients enrolled between September 2011
and August 2012. The mean IOP significantly decreased from 19.5±2.5 and 20.2±3.2 mm Hg preoperatively to
15.6±3.4 and 15.3±3.1 mm Hg postoperatively at 3 months in phakic and pseudophakic group respectively. Mean
IOP reduction was not significantly different between phakic (3.9± 3.1 mmHg) and pseudophakic group (5.0±3.06
mmHg, p=0.197). The non-inferiority test indicated that mean IOP reduction in pseudophakic group was noninferior
to phakic group (p=0.012).
Conclusion: SLT was effective for IOP reduction in both phakic and pseudophakic eyes with OAG. The efficacy of
SLT in pseudophakic eyes was not inferior to phakic eyes
Endogenous panophthalmitis in a patient with COVID-19 during hospitalization in an intensive care unit: A case report
Purpose: To report a case of endogenous panophthalmitis in a patient with COVID-19 during treatment in an Intensive Care Unit. Observation: A 64‐year‐old woman with COVID-19 and Salmonella septicemia presented with decreased visual acuity, ocular pain, and proptosis in her right eye after treatment with favipiravir, intravenous dexamethasone, and ceftriaxone. An ocular examination of her right eye revealed periorbital tenderness, exophthalmos, and corneal haze. The ultrasonography showed a subretinal abscess. Her right eye lost light perception vision and underwent enucleation. Microbiologic evaluation of the enucleated right eye was negative for organisms. Conclusions and importance: Patents with COVID-19 may develop severe ocular involvement after COVID-19 due to a generalized reduction in immunity. Comorbidities and intensive care unit treatments can predispose COVID-19 patients to endogenous panophthalmitis

Genome-wide association study identifies five new susceptibility loci for primary angle closure glaucoma.
Primary angle closure glaucoma (PACG) is a major cause of blindness worldwide. We conducted a genome-wide association study (GWAS) followed by replication in a combined total of 10,503 PACG cases and 29,567 controls drawn from 24 countries across Asia, Australia, Europe, North America, and South America. We observed significant evidence of disease association at five new genetic loci upon meta-analysis of all patient collections. These loci are at EPDR1 rs3816415 (odds ratio (OR) = 1.24, P = 5.94 × 10(-15)), CHAT rs1258267 (OR = 1.22, P = 2.85 × 10(-16)), GLIS3 rs736893 (OR = 1.18, P = 1.43 × 10(-14)), FERMT2 rs7494379 (OR = 1.14, P = 3.43 × 10(-11)), and DPM2-FAM102A rs3739821 (OR = 1.15, P = 8.32 × 10(-12)). We also confirmed significant association at three previously described loci (P < 5 × 10(-8) for each sentinel SNP at PLEKHA7, COL11A1, and PCMTD1-ST18), providing new insights into the biology of PACG

Genetic Association Study Of Exfoliation Syndrome Identifies A Protective Rare Variant At Loxl1 And Five New Susceptibility Loci
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 x 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 x 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.Wo
