Fundus Autofluorescence Images in Gas-filled Eyes Immediately After Macular Hole Surgery

Fundus Autofluorescence Images in Gas-filled Eyes Immediately After Macular Hole Surgery ABSTRACT Purpose: Preoperative fundus autofluorescence (FAF) image in idiopathic macular hole (MH) is described to reflect anatomical changes of hyperfluorescent MH, hypofluorescent fluid cuff, relatively hypofluorescent intraretinal cysts. Postoperative disappearance of hyperfluorescent MH after surgically closed MH represents blockage of FAF from...

Application of OCTA to the Iris: Relevance to Diabetic Retinopathy

Application of OCTA to the Iris: Relevance to Diabetic Retinopathy ABSTRACT OCTA is a relatively new imaging modality that is used to assess retinal vasculature without the use of intravenous dyes. It has been applied extensively in the evaluation of retinal vascular and inflammatory diseases. More recently it has been applied for the study of iris vessels in the setting of uveitis in an effort to help monitor treatment responses and...

OCT-A in Macular Surgery

OCT-A in Macular Surgery ABSTRACT Purpose: To evaluate vessel density changes in the superficial and deep vessel plexus, and FAZ area before and after macular surgery. Materials & Methods: 50 consecutive patients (25 with macular pucker and 25 with macular hole) were examined with OCT-A (RTVue-XR Avanti; Optovue, Fremont, CA, USA) before macular surgery and 1 week, 1 month, 3 months, and 12 months after surgery. Vessel density of the...
