    1. Peripapillary microvasculature in patients with diabetes mellitus: An optical coherence tomography angiography study

      Peripapillary microvasculature in patients with diabetes mellitus: An optical coherence tomography angiography study

      To evaluate changes in peripapillary microvascular parameters in diabetes mellitus (DM) patients using optical coherence tomography angiography (OCTA). Seventy-one diabetic patients (40 in the no diabetic retinopathy [DR] group and 31 in the non-proliferative DR [NPDR] group) and 50 control subjects. OCTA (Zeiss HD-OCT 5000 with AngioPlex) 6 × 6 mm scans centered on the optic disc were analyzed. Peripapillary vessel density (VD), perfusion density (PD) in superficial capillary plexus (SCP) were automatically calculated. The average macular ganglion cell-inner plexiform layer (mGC-IPL) and peripapillary retinal nerve fiber layer (pRNFL) thicknesses of the no DR and NPDR groups were significantly thinner than ...

    2. Longitudinal Changes of Retinal Thicknesses in Branch Retinal Artery Occlusion: Spectral-Domain Optical Coherence Tomography Study

      Longitudinal Changes of Retinal Thicknesses in Branch Retinal Artery Occlusion: Spectral-Domain Optical Coherence Tomography Study

      Purpose : To analyze longitudinal thickness changes in the overall macula, ganglion cell–inner plexiform layer (GC-IPL), and peripapillary retinal nerve fiber layer (pRNFL) using spectral-domain optical coherence tomography in branch retinal artery occlusion (BRAO). Methods : A prospective analysis was conducted in patients with BRAO. The thicknesses of the overall macula, GC-IPL, and pRNFL were measured at the initial visit, and at 1, 3, 6, and 12 months. Changes in the occluded areas of the affected and unaffected eyes were analyzed, and the nonoccluded areas were compared. Results : In the occluded areas of the affected eyes, the only overall macular thickness ...

    3. Long-term reproducibility of GC-IPL thickness measurements using spectral domain optical coherence tomography in eyes with high myopia

      Long-term reproducibility of GC-IPL thickness measurements using spectral domain optical coherence tomography in eyes with high myopia

      Although ganglion cell inner plexiform layer (GC-IPL) analysis in the patients with high myopia is useful, there have been few reports to analyze of the reliability for long-term measured GC-IPL thickness. We aimed to analyze the long-term reproducibility of thickness measurements of the GC-IPL using spectral-domain optical coherence tomography (SD-OCT) in patients with high myopia and identify factors that affect such reproducibility. 99 eyes from 99 patients with high myopia without any other ophthalmc disorder such as glaucoma or retinal diseases were included. Two serial SD-OCT (Cirrus-HD) macular scans taken at ≧ 1 year intervals were analyzed. The intraclass correlation coefficient ...

    4. Repeatability of vessel density measurements using optical coherence tomography angiography in retinal diseases

      Repeatability of vessel density measurements using optical coherence tomography angiography in retinal diseases

      Aim To analyse the repeatability of vessel density (VD) measurements using optical coherence tomography angiography (OCTA) in patients with retinal diseases. Methods Two consecutive VD measurements using OCTA were analysed prospectively in patients with retinal diseases (diabetic macular oedema (DME), retinal vein occlusion (RVO) with macular oedema, epiretinal membrane (ERM), wet age-related macular degeneration (AMD)). The intraclass correlation coefficient (ICC), coefficient of variation (CV) and test-retest SD of VD measurements were assessed, and linear regression analyses were conducted to identify factors related to repeatability. Results A total of 134 eyes were analysed involving 20 eyes with DME, 44 eyes with ...

    5. Prediction of Retinal Ischemia in Branch Retinal Vein Occlusion: Spectral-Domain Optical Coherence Tomography Study

      Prediction of Retinal Ischemia in Branch Retinal Vein Occlusion: Spectral-Domain Optical Coherence Tomography Study

      Purpose : To investigate the relationship between spectral-domain optical coherence tomography (SD-OCT) measurements and retinal nonperfusion in patients with branch retinal vein occlusion (BRVO). Methods : Forty-one patients with BRVO who had recovered from macular edema and had been followed for ≥2 years were included via retrospective, medical record review. Patients were divided into two groups that included 20 nonischemic eyes and 21 ischemic eyes, and 41 fellow control eyes were also included. Using SD-OCT, we measured the thickness of the macular layer, ganglion cell–inner plexiform layer (GC-IPL), and retinal nerve fiber layer (RNFL) in both the BRVO-affected and fellow eyes ...
