    2. Swept-Source Optical Coherence Tomography Angiography of Microaneurysms in Myopic Retinoschisis

      Swept-Source Optical Coherence Tomography Angiography of Microaneurysms in Myopic Retinoschisis
      A woman in her early 30s presented with floaters that had been present for several years. Her best-corrected visual acuity was 1.5 (20/13) OU. Axial length was 27.93 mm OD and 27.35 mm OS. Numerous aneurysms were observed temporal to the macula, predominantly in the left eye ( Figure , A). Swept-source optical coherence tomography angiography confirmed that these aneurysms were located in the retinoschisis cavity ( Figure , B ...

      MACULAR ATROPHY FINDINGS BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY COMPARED WITH FUNDUS AUTOFLUORESCENCE IN TREATED EXUDATIVE AGE-RELATED MACULAR DEGENERATION
      Purpose: To compare the areas of choriocapillaris (CC) nonperfusion and macular atrophy (MA) in treated exudative age-related macular degeneration. Methods: This was a prospective, observational, cross-sectional study. Forty-four eyes exhibiting MA (42 patients with age-related macular degeneration), with a dry macula, underwent fundus autofluorescence and optical coherence tomography angiography. The area of MA detected by fundus autofluorescence and CC nonperfusion detected by optical coherence tomography angiography was measured using image ...

    9. Diabetic Neuroglial Changes in the Superficial and Deep Nonperfused Areas on Optical Coherence Tomography Angiography

      Diabetic Neuroglial Changes in the Superficial and Deep Nonperfused Areas on Optical Coherence Tomography Angiography
      Purpose : To evaluate the relationship between lamellar capillary nonperfusion on optical coherence tomography angiography (OCTA) images and neuroglial changes on structural optical coherence tomography (OCT) images in diabetic retinopathy (DR). Methods : We retrospectively reviewed 101 consecutive eyes of 69 patients with DR. OCTA and OCT images within a 3 3-mm square centered on the fovea were acquired simultaneously.

    13. Optical Coherence Tomography Angiography to Estimate Retinal Blood Flow in Eyes with Retinitis Pigmentosa

      Optical Coherence Tomography Angiography to Estimate Retinal Blood Flow in Eyes with Retinitis Pigmentosa
      Ophthalmologists sometimes face difficulties in identifying the origin of visual acuity (VA) loss in a retinitis pigmentosa (RP) patient, particularly before cataract surgery: cataract or the retinal disease state. Therefore, it is important to identify the significant factors correlating with VA. Nowadays, retinal blood flow in superficial and deep layers can be estimated non-invasively using optical coherence tomography angiography (OCTA). We estimated blood flow per retinal layer by using OCTA ...
