BACKGROUND AND OBJECTIVE: To evaluate the repeatability, reliability, and comparability of macular thickness measurements between three optical coherence tomography (OCT) machines in healthy eyes, eyes with diabetic macular edema (DME), and eyes with neovascular age-related macular degeneration (nAMD). PATIENTS AND METHODS: Twenty-three eyes with DME, 26 eyes with nAMD, and 24 healthy eyes as controls were evaluated. Scans were performed using the swept-source Triton (Topcon, Tokyo, Japan), the spectral-domain Cirrus (Carl Zeiss Meditec, Dublin, CA), and the Spectralis (Heidelberg Engineering, Heidelberg, Germany) machines...

BACKGROUND AND OBJECTIVE: To determine the correlation between mesopic retinal sensitivity and optical coherence tomographic metrics of the outer retina in patients with intermediate age-related macular degeneration (AMD). PATIENTS AND METHODS: Participants with nonatrophic dry AMD underwent mesopic MP-3 microperimetry (Nidek, Padova, Italy) and both Nidek and Cirrus (Carl Zeiss Meditec, Dublin, CA) spectral-domain optical coherence tomography (SD-OCT). The volume of the outer retinal layers was measured on the Nidek SD-OCT scans using the automatic segmentation algorithm of Navis-EX software...

Neuroretinitis is a form of papillitis associated with the delayed onset of an exudative macular star among other inflammatory ocular findings. We describe 4 patients with neuroretinitis who displayed several distinctive and novel findings on spectral-domain optical coherence tomography (OCT) that include "epipapillary infiltrates" and an atypical pattern of inner retinal folds. The recognition of these findings on OCT may help in the early diagnosis of neuroretinitis.

INTRODUCTION: This study aimed to evaluate the ability of 2 optical coherence tomographic (OCT) systems to detect apical dentinal microcracks. METHODS: Twenty extracted human single-rooted mandibular incisors were selected. After root canal preparation with an R40 Reciproc file (VDW, Munich, Germany), the specimens presenting apical microcracks were identified using micro-computed tomographic (micro-CT) scanning as the gold standard. Then, the apical portions of the roots were imaged with spectral domain OCT (SD-OCT) and swept-source OCT systems, and the resulting images were blindly evaluated by 3 independent examiners to detect microcracks...

PURPOSE: To report the efficacy and safety of interferon (IFN) α-2a in patients with cystoid macular edema (CME) associated with presumed ocular tuberculosis (TB). METHODS: We reviewed the clinical records of 5 patients with presumed ocular TB who had been treated with IFN α-2a for recurrent CME during or after completion of anti-tubercular therapy. IFN α-2a was administered at an initial dose of 3 million IU per day and then tapered after the initial response...

PURPOSE: Standard evaluation of aberrations from wavefront slope measurements in patients implanted with a rotationally asymmetric multifocal intraocular lens (IOL), the Lentis Mplus (Oculentis GmbH, Berlin, Germany), results in large magnitude primary vertical coma, which is attributed to the intrinsic IOL design. The new proposed method analyzes aberrometry data, allowing disentangling the IOL power pupillary distribution from the true higher order aberrations of the eye. METHODS: The new method of wavefront reconstruction uses retinal spots obtained at both the near and far foci...

PURPOSE: To comparatively investigate changes in epithelial thickness between myopic femtosecond laser-assisted LASIK (FS-LASIK) and small incision lenticule extraction (SMILE). METHODS: This study compared the topographic epithelial thickness changes in 175 myopic eyes undergoing FS-LASIK (62 eyes) or SMILE (113 eyes). Epithelial thickness was obtained using spectral-domain optical coherence tomography before surgery and 1 and 3 months after surgery.

BACKGROUND: To evaluate macular changes in fellow eyes of patients diagnosed with lamellar macular hole (LMH) using spectral-domain optical coherence tomography (SD-OCT) and blue fundus autofluorescence (B-FAF). METHODS: Fellow eyes of patients diagnosed with a LMH were retrospectively evaluated on OCT. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were recorded. Corresponding B-FAF images, vitreo-macular relations, and type of epiretinal membranes (ERMs) were also examined...

We present the three-dimensional (3D) spectral-domain optical coherence tomography (SD-OCT) findings of schisis-like maculopathy associated with structural changes of the optic nerve (ON) head as well as the treatment outcomes of a case of advanced glaucoma. In addition to ophthalmological examination, B-scan and 3D-SD-OCT images of the ON head, peripapillary retina, and the macula were obtained. The B-scan images only detected typical retinoschisis findings. However, the 3D-SD-OCT images of the ON head revealed defects of various sizes, shapes, and depths at the outer wall of the prelaminar and laminar regions of the ON canal...

Choroid has been proposed to participate in the regulation of light refraction by changing its thickness. The present study aims to analyze the characteristics of choroidal thickness (CT), and its correlation with refractive error, axial length and age in young ametropia. A total of 51 subjects (102 eyes), aged from 5 to 18 years old (mean age 10.04 ±2.78 years), with ametropia were included in the study. Choroidal imaging was obtained by enhanced depth imaging (EDI) of spectral domain Optical Coherence Tomography (OCT)...
