Journal ArticleDOI
Digital Screen Time During the COVID-19 Pandemic: Risk for a Further Myopia Boom?
Chee Wai Wong,Andrew S H Tsai,Jost B. Jonas,Kyoko Ohno-Matsui,James Chen,Marcus Ang,Daniel Shu Wei Ting +6 more
TL;DR: Increased digital screen time, near work and limited outdoor activities were found to be associated with the onset and progression of myopia, and could potentially be aggravated during and beyond the COVID-19 pandemic outbreak period.
Journal ArticleDOI
Prognostic factor analysis of vitrectomy for retinal detachment associated with myopic macular holes.
Laurence Shen Lim,Andrew S H Tsai,Doric Wong,Edmund Wong,Ian Yeo,Boon Kwang Loh,Chong Lye Ang,Sze Guan Ong,Shu Yen Lee +8 more
TL;DR: In this article, the authors describe the anatomic and functional outcomes in a cohort of subjects undergoing vitrectomy for retinal detachment (RD) resulting from myopic macular hole (MH) and analyze the prognostic and surgical factors predicting retinal reattachment and MH closure.
Journal ArticleDOI
Retinal angiomatous proliferation
Andrew S H Tsai,Ning Cheung,Alfred Tau Liang Gan,Glenn J. Jaffe,Sobha Sivaprasad,Tien Yin Wong,Chui Ming Gemmy Cheung +6 more
TL;DR: Retinal angiomatous proliferation may portend a more guarded visual prognosis than typical choroidal neovascularization because of variable treatment response and dependence on the disease stage.
Journal ArticleDOI
Global Assessment of Retinal Arteriolar, Venular and Capillary Microcirculations Using Fundus Photographs and Optical Coherence Tomography Angiography in Diabetic Retinopathy.
Tien-En Tan,Quang Nguyen,Jacqueline Chua,Leopold Schmetterer,Gavin Tan,Chee Wai Wong,Andrew S H Tsai,Gemmy Cheung,Tien Yin Wong,Daniel Shu Wei Ting +9 more
TL;DR: It is concluded that the retinal microvasculature is globally affected in severe DR, reflecting widespread microvascular impairment in perfusion.
Journal ArticleDOI
DIABETIC MACULAR ISCHEMIA: Correlation of Retinal Vasculature Changes by Optical Coherence Tomography Angiography and Functional Deficit
Andrew S H Tsai,Alfred Tau Liang Gan,Daniel S W Ting,Chee Wai Wong,Kelvin Yi Chong Teo,Anna C S Tan,Shu Yen Lee,Tien Yin Wong,Gavin Tan,Chui Ming Gemmy Cheung +9 more
TL;DR: Altered changes in retinal microvasculature can be observed with OCTA with increasing severity of DR, and these changes are correlated with reduced retinal sensitivity.
