Methodology of the Singapore Indian Chinese Cohort (SICC) Eye Study: Quantifying ethnic variations in the epidemiology of eye diseases in Asians
Raghavan Lavanya,Vse Jeganathan,Yingfeng Zheng,P Raju,Ning Cheung,E-Shyong Tai,Jie Jin Wang,Ecosse L. Lamoureux,Paul Mitchell,Terri L. Young,Howard Cajucom-Uy,Paul J. Foster,Tin Aung,Seang-Mei Saw,Tien Yin Wong +14 more
TL;DR: In conjunction with the Singapore Malay Eye Study, the SICC study will permit an in-depth evaluation of the prevalence, risk factors, and impact of major eye diseases in Chinese, Indians and Malays, three distinct Asian ethnic groups, whose combined numbers represent half the world’s population.
Journal ArticleDOI
Comparison of Gonioscopy and Anterior Segment Ocular Coherence Tomography in Detecting Angle Closure in Different Quadrants of the Anterior Chamber Angle
Lisandro M. Sakata,Raghavan Lavanya,David S. Friedman,Han T. Aung,Hong Gao,Rajesh S. Kumar,Paul J. Foster,Tin Aung +7 more
TL;DR: Anterior segment OCT tended to detect more closed ACAs than gonioscopy, particularly in the superior and inferior quadrants, and Variations in the iris profile and level of iridoangle contact also may explain some of the differences seen between Gonioscopy and AS OCT.
Journal ArticleDOI
Assessment of the Scleral Spur in Anterior Segment Optical Coherence Tomography Images
Lisandro M. Sakata,Raghavan Lavanya,David S. Friedman,Han T. Aung,Steve K. L. Seah,Paul J. Foster,Tin Aung +6 more
TL;DR: The inability to detect the scleral spur may hamper quantitative analysis of anterior chamber angle parameters that are dependent on the location of this anatomical structure, particularly in the superior and inferior quadrants.

TL;DR: A genome-wide association study including 1,854 PACG cases and 9,608 controls across 5 sample collections in Asia suggests possible mechanisms explaining the pathogenesis of PACG.

Quantitative Iris Parameters and Association with Narrow Angles
Bingsong Wang,Lisandro M. Sakata,Lisandro M. Sakata,David S. Friedman,Yiong Huak Chan,Mingguang He,Raghavan Lavanya,Tien Yin Wong,Tien Yin Wong,Tin Aung,Tin Aung +10 more
TL;DR: Quantitative iris parameters (I-Curv, I-Area, and iris thickness) are independently associated with narrow angles, particularly in women and older subjects.
