    1. Evaluation of Pachymetric Measurements with Scheimpflug Photography-Based System and Optical Coherence Tomography Pachymetry at Different Stages of Keratoconus

      Evaluation of Pachymetric Measurements with Scheimpflug Photography-Based System and Optical Coherence Tomography Pachymetry at Different Stages of Keratoconus

      The aim of this study was to compare the central and peripheral pachymetric measurements determined with Sirius system and Visante OCT and evaluate the agreement between them at different stages of keratoconus. Measurements were not significantly different in all patients and subgroups and showed high correlation for the corneal thicknesses of the entire cornea in different stages of keratoconus.

    2. Comparison of conjunctival graft thickness after primary and recurrent pterygium surgery: Anterior segment optical coherence tomography study

      Comparison of conjunctival graft thickness after primary and recurrent pterygium surgery: Anterior segment optical coherence tomography study

      Objective: The objective of the following study is to compare the conjunctival graft thickness measured with anterior segment optical coherence tomography (OCT) after primary and recurrent pterygium excision. Design: Prospective, interventional and comparative study. Participants: A total of 20 eyes of 20 patients with primary pterygium (primary group) and 20 eyes of 20 patients with recurrent pterygium (recurrent group) were enrolled. Materials and Methods: All patients underwent pterygium excision with conjunctival autograft transplantation. Conjunctival graft thickness was measured at 1 week, 1 month and 3 months after surgery using the Visante-OCT (Carl-Zeiss Meditec, Dublin, CA, USA). Main outcome measure was ...

    3. IDIOPATHIC AND SECONDARY EPIRETINAL MEMBRANES: Do They Differ in Terms of Morphology? An Optical Coherence Tomography–Based Study

      IDIOPATHIC AND SECONDARY EPIRETINAL MEMBRANES: Do They Differ in Terms of Morphology? An Optical Coherence Tomography–Based Study
      Purpose: The purpose of this study was to define the morphologic differences in idiopathic and secondary epiretinal membranes (ERMs) using a time domain optical coherence tomography. Methods: The medical records and optical coherence tomography images of 293 eyes of 236 consecutive patients diagnosed to have ERM were evaluated retrospectively. Demographic features, best-corrected visual acuities, central macular thickness, membrane attachment patterns, macular changes, and the presence of posterior retinal detachment at the time of diagnosis were compared between the groups (idiopathic group, n = 125 eyes; secondary group, n = 168 eyes). Results: The mean age was higher among idiopathic ERMs (67 ± 9 ...

    4. Central Corneal Thickness, Anterior Chamber Depth, and Pupil Diameter Measurements Using Visante OCT, Orbscan, and Pentacam

      PURPOSE To evaluate the agreement among three different optical methods in measuring anterior chamber depth (ACD), central corneal thickness (CCT), and pupil diameter. METHODS One hundred eyes of 50 healthy patients (25 men, 25 women) were enrolled in the study. Mean patient age was 25 years (range: 21 to 32 years). Exclusion criteria were history of any intraocular or corneal surgery, contact lens wear, corneal anomalies, and spherical refraction >5.00 diopters (D) or cylindrical refraction >2.00 D. All measurements were done by the same operator under mesopic light conditions and repeated using three different optical methods: Visante optical ...
