    1. Impact of swept source optical coherence tomography on ophthalmology

      Impact of swept source optical coherence tomography on ophthalmology

      Swept source optical coherence tomography (SS-OCT) was introduced in clinical practice in 2012. Because of its deeper penetration and faster acquisition time, SS-OCT has the ability to visualize choroid, vitreous, and retinal structures behind dense preretinal hemorrhages. Swept source optical coherence tomography has positively influenced and hugely contributed to the research of the vitreous body. It is the first ophthalmic diagnostic technology to demonstrate the entire structure of the posterior precortical vitreous pocket (PPVP) in vivo . The roles of the PPVP in physiological posterior vitreous detachment and vitreoretinal interface disorders have now been elucidated. The presence of a connecting channel ...

    2. Retinal complications associated with congenital optic disc anomalies determined by swept source optical coherence tomography

      Retinal complications associated with congenital optic disc anomalies determined by swept source optical coherence tomography

      Optical coherence tomography has evolved over the past 2 decades to be an important ancillary method to evaluate diseases of the anterior and posterior segments of the eye. The more recent development of swept-source optical coherence tomography (SS-OCT) with a wavelength-tunable laser centered at 1050 nm and deeper imaging depth of 2.6 mm has enabled clinicians to evaluate congenital optic disc anomalies including optic disc pits, optic disc colobomas, and morning glory syndrome in more detail. The SS-OCT findings of the posterior precortical vitreous pocket, Cloquet's canal, lamina cribrosa that is torn from the peripapillary sclera, and the ...

    3. A novel view of punctate inner choroidopathy: Characterizing the serial changes by high resolution spectrum-domain optical coherence tomography

      A novel view of punctate inner choroidopathy: Characterizing the serial changes by high resolution spectrum-domain optical coherence tomography

      Purpose We report a case of punctate inner choroidopathy (PIC) treated with oral prednisolone and intravitreous bevacizumab injection (IVB). Methods One case was studied and followed for 5 months by serial spectrum-domain optical coherence tomography (SD-OCT). Results At the early active phase of PIC, SD-OCT showed dome-shaped retinal pigment epithelium (RPE) elevation with underlying intact Bruch's membrane (BM), overlying photoreceptor inner/outer segment junction (PRJ) disappearance, and homogenous hyperreflective sub-RPE signals. After oral prednisolone and IVB, SD-OCT showed resolution of RPE changes with overlying intact PRJ. Further, the localized outer retinal layers were found to gradually move outward. Conclusions ...

    4. Choroidal changes by ocular coherence tomography in white dot syndrome

      Choroidal changes by ocular coherence tomography in white dot syndrome

      Purpose To evaluate the findings of optical coherence tomography (OCT) in the acute and convalescent stages in patients with white dot syndrome. Patients were followed up at our clinic for at least 6 months. Materials and methods A consecutive case series of patients with white dot syndrome were enrolled in this study. Only patients with disease onset less than 1 week were included in this study. Slit-lamp biomicroscopy, indirect ophthalmoscopy, fluorescein angiography, indocyanine green angiography (ICGA), OCT, visual field test, and corrected decimal visual acuity test were performed on all patients. Results A total of eight eyes from eight patients ...

    5. Agreement and repeatability of central corneal thickness measurements made by ultrasound pachymetry and anterior segment optical coherence tomography

      Agreement and repeatability of central corneal thickness measurements made by ultrasound pachymetry and anterior segment optical coherence tomography

      Purpose To evaluate repeatability within and between examiners and to assess agreement in corneal thickness measurements obtained by anterior segment optical coherence tomography (ASOCT) and ultrasonic pachymetry (USP). Methods This was a prospective, observational study. Fifty-one patients who visited a glaucoma service with suspected glaucoma, glaucoma, or cataract were enrolled. Patients with a history of corneal surgery or abnormalities and those who were uncooperative for examinations were excluded. Each patient underwent ASOCT followed by USP, with each test performed by two different examiners. Measurement repeatability was evaluated using intraclass correlation coefficient (ICC) values. Agreement in corneal thickness measurements was evaluated ...

    6. Optical coherence tomography (OCT) findings in patients with optic tract syndrome

      Optical coherence tomography (OCT) findings in patients with optic tract syndrome
      Purpose To analyze retinal nerve fiber layer (RNFL) thickness in eyes with optic tract syndrome (OTS) by using optical coherence tomography (OCT) and to evaluate the capability of OCT to detect the characteristic pattern of RNFL loss. Methods Eight patients (4 males and 4 females) with optic tract syndrome were enrolled in this retrospective collection of medical records. Characteristics including age, sex, etiology of optic tract lesion, visual acuity, visual field defect type were recorded. The diagnosis of optic tract syndrome were made by clinical history and typical optic disc findings, visual field defect and neuro-imaging findings including brain MRI ...
