    1. Optical coherence tomography angiographic findings of lamellar macular hole: comparisons between tractional and degenerative subtypes

      Optical coherence tomography angiographic findings of lamellar macular hole: comparisons between tractional and degenerative subtypes
      We investigated the microvascular changes in eyes with lamellar macular holes (LMHs) using optical coherence tomography angiography (OCTA), compare them between two subtypes of LMH. Tractional and degenerative LMH were differentiated based on the morphological characteristics of OCT. In OCTA images, foveal and parafoveal vessel density (VD) in the superficial and deep capillary plexus (SCP, DCP) and foveal avascular zone (FAZ) area were measured. Eyes that underwent vitrectomy for LMH ...

    2. OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN PATIENTS WITH RETINITIS PIGMENTOSA–ASSOCIATED CYSTOID MACULAR EDEMA

      OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN PATIENTS WITH RETINITIS PIGMENTOSA–ASSOCIATED CYSTOID MACULAR EDEMA
      Purpose: To investigate the microstructure of cystoid macular edema (CME) in retinitis pigmentosa (RP) and the associated vascular changes using optical coherence tomography (OCT) angiography. Methods: In this retrospective study, we included 42 eyes of 21 patients with RP and age-similar normally sighted controls who underwent both OCT and optical coherence tomography angiography . Using OCT, spatial distribution of CME and the retinal layer, which CME located, was examined. Optical coherence ...

    3. Optical coherence tomography angiography findings of type 1 diabetic patients with diabetic retinopathy, in comparison with type 2 patients

      Optical coherence tomography angiography findings of type 1 diabetic patients with diabetic retinopathy, in comparison with type 2 patients
      Purpose To compare optical coherence tomography angiography (OCT-A) parameters between type 1 and type 2 diabetic patients with diabetic retinopathy (DR). Methods A total of 70 patients with type 1 diabetes and 70 with type 2 diabetes were retrospectively analyzed. DR was graded as no DR, mild nonproliferative DR (NPDR), moderate NPDR, severe NPDR, and proliferative DR (PDR). Using OCT-A, the foveal avascular zone (FAZ) area (mm 2 ) and vascular ...

    4. Optical Coherence Tomography Angiographic Findings of Tamoxifen Retinopathy: Similarity with Macular Telangiectasia Type 2

      Optical Coherence Tomography Angiographic Findings of Tamoxifen Retinopathy: Similarity with Macular Telangiectasia Type 2
      Purpose We aimed to describe the vascular changes in eyes associated with tamoxifen retinopathy using optical coherence tomography angiography (OCTA) and to compare these changes with abnormalities in macular telangiectasia type 2 (MacTel2) previously reported in the literature. Design Retrospective, observational study Participants Seventeen eyes with tamoxifen retinopathy and 17 eyes of age-matched normal controls. Methods The medical records of patients who visited the ophthalmology department with a history of ...

    5. Macular capillary plexuses after epiretinal membrane surgery: an optical coherence tomography angiography study

      Macular capillary plexuses after epiretinal membrane surgery: an optical coherence tomography angiography study
      Aims To investigate macular vascular integrity using optical coherence tomography angiography (OCTA) in patients undergoing vitrectomy for idiopathic epiretinal membrane (ERM) removal and to determine its association with structural and visual outcomes. Methods Forty-three patients with unilateral ERM who were followed for 6 months after surgery were included. Ophthalmological evaluations included best-corrected visual acuity (BCVA) and spectral-domain OCT (SD-OCT) before surgery and 6 months after surgery. We obtained en face ...

    6. Macular capillary plexuses after macular hole surgery: an optical coherence tomography angiography study

      Macular capillary plexuses after macular hole surgery: an optical coherence tomography angiography study
      Aims To investigate the structural changes of the superficial capillary plexuses (SCP) and deep capillary plexuses (DCP) using optical coherence tomography (OCT) angiography (OCTA) in patients with idiopathic macular hole (MH) after surgery, determine the factors related to changes of macular capillary plexuses and evaluate its association with postoperative visual outcomes. Methods Thirty-three patients with unilateral MH who were followed for 6 months after surgery were included. Ophthalmologic evaluations included ...

    7. Correlation between Spectral-Domain OCT findings and Visual Acuity in X-linked Retinoschisis

      Correlation between Spectral-Domain OCT findings and Visual Acuity in X-linked Retinoschisis
      PURPOSE: To investigate the tomographic characteristics of the outer retina and choroid and their relationship with visual auity in X-linked juvenile retinoschisis (XLRS) patients using spectral-domain optical coherence tomography (SD-OCT). METHODS: In this retrospective, observational, case-control study, we analyzed 20 eyes of 10 patients with XLRS using SD-OCT. The clinical and tomographic features of the outer retina, including the external limiting membrane (ELM), inner segment/outer segment (IS/OS) junction ...

    8. Macular Gradient Measurement in Myopic Posterior Staphyloma Using Optical Coherence Tomography

      Macular Gradient Measurement in Myopic Posterior Staphyloma Using Optical Coherence Tomography
      Purpose To evaluate clinical characteristics and the macular gradient in myopic posterior staphyloma with time domain (TD) optical coherence tomography (OCT). Methods Sixty-four staphyloma eyes of 40 patients were examined. Macular gradient (tangent θ) and the location of staphyloma were assessed with OCT imaging. The macular gradient was measured at points 1 mm and 2 mm distant from the fovea. The relationships of the macular gradient with age, axial length ...

    9. Correlation of Microperimetry with Fundus Autofluorescence and Spectral-Domain Optical Coherence Tomography in Repaired Macular Holes

      Correlation of Microperimetry with Fundus Autofluorescence and Spectral-Domain Optical Coherence Tomography in Repaired Macular Holes
      Purpose: To investigate the correlation of microperimetry with fundus autofluorescence (FAF), spectral-domain optical coherence tomography (SD-OCT), and visual acuity (VA) in order to better characterize visual outcomes after successful macular hole (MH) surgery.Design: Cross-sectional case series.Methods: Postoperative VA, microperimetry, FAF, and SD-OCT images from 23 eyes of 23 patients who underwent successful MH surgery were obtained. FAF images were examined using the Heidelberg retina angiograph 2, and foveal ...
