Journal ArticleDOI
Classification of Human Retinal Microaneurysms Using Adaptive Optics Scanning Light Ophthalmoscope Fluorescein Angiography
Michael Dubow,Michael Dubow,Alexander Pinhas,Alexander Pinhas,Nishit Shah,Robert F. Cooper,Alexander Gan,Ronald C. Gentile,Ronald C. Gentile,Ronald C. Gentile,Vernon Hendrix,Yusufu N. Sulai,Joseph Carroll,Joseph Carroll,Toco Yuen Ping Chui,Joseph B. Walsh,Rishard Weitz,Alfredo Dubra,Alfredo Dubra,Richard B Rosen,Richard B Rosen +20 more
TL;DR: Adaptive optics scanning light ophthalmoscope fluorescein angiography imaging of MAs offers the possibility of studying microvascular change on a histologic scale, which may help the understanding of disease progression and treatment response.
Journal ArticleDOI
Assessment of perfused foveal microvascular density and identification of nonperfused capillaries in healthy and vasculopathic eyes.
Alexander Pinhas,Moataz M Razeen,Michael Dubow,Michael Dubow,Alexander Gan,Toco Yuen Ping Chui,Toco Yuen Ping Chui,Nishit Shah,Mitul C Mehta,Ronald C. Gentile,Rishard Weitz,Joseph B. Walsh,Yusufu N. Sulai,Joseph Carroll,Alfredo Dubra,Richard B Rosen,Richard B Rosen +16 more
TL;DR: In vivo adaptive optics scanning light ophthalmoscope fluorescein angiography provides an in vivo method for estimating foveal microvascular density and reveals occult nonperfused retinal capillaries in healthy young adults.
Journal ArticleDOI
Comparison of Adaptive Optics Scanning Light Ophthalmoscopic Fluorescein Angiography and Offset Pinhole Imaging
Toco Yuen Ping Chui,Michael Dubow,Alexander Pinhas,Nishit Shah,Alexander Gan,Rishard Weitz,Yusufu N. Sulai,Alfredo Dubra,Richard B Rosen +8 more
TL;DR: AOSLO offset pinhole (OP) imaging combined with motion contrast post-processing techniques, are able to create a similar set of structural and perfusion images without the use of exogenous contrast agent, and offers a non-invasive alternative to AOSLO FA without the need for any exogenous Contrast agent.
Journal ArticleDOI
Longitudinal imaging of microvascular remodelling in proliferative diabetic retinopathy using adaptive optics scanning light ophthalmoscopy
Toco Yuen Ping Chui,Toco Yuen Ping Chui,Alexander Pinhas,Alexander Pinhas,Alexander Gan,Moataz M Razeen,Moataz M Razeen,Nishit Shah,Eric Cheang,Chun L Liu,Chun L Liu,Alfredo Dubra,Alfredo Dubra,Richard B Rosen,Richard B Rosen +14 more
TL;DR: To characterise longitudinal changes in the retinal microvasculature of type 2 diabetes mellitus (T2DM) as exemplified in a patient with proliferative diabetic retinopathy (PDR) using an adaptive optics scanning light ophthalmoscope (AOSLO).
Journal ArticleDOI
FELLOW EYE CHANGES IN PATIENTS WITH NONISCHEMIC CENTRAL RETINAL VEIN OCCLUSION: Assessment of Perfused Foveal Microvascular Density and Identification of Nonperfused Capillaries.
Alexander Pinhas,Michael Dubow,Nishit Shah,Eric Cheang,Chun L Liu,Moataz M Razeen,Alexander Gan,Rishard Weitz,Yusufu N. Sulai,Toco Yuen Ping Chui,Alfredo Dubra,Richard B Rosen +11 more
TL;DR: Fellow eye changes detectable on adaptive optics scanning light ophthalmoscope fluorescein angiography reflect subclinical pathology difficult to detect using conventional imaging technologies and may help elucidate the pathogenesis of nonischemic CRVO and help identify eyes at increased risk of future occlusion.
