    4. Preoperative and Postoperative Optical Coherence Tomography Findings in Patients with Rhegmatogenous Retinal Detachment Involving the Macular Region

      Preoperative and Postoperative Optical Coherence Tomography Findings in Patients with Rhegmatogenous Retinal Detachment Involving the Macular Region

      Purpose . To evaluate morphologic changes of the macula, we observed eyes with rhegmatogenous retinal detachment (RRD) involving the macular region by optical coherence tomography (OCT). Subjects and Methods . We studied 26 eyes with RRD before and after surgery, assessing visual acuity, the height of retinal detachment at the fovea (HRD), and morphologic changes of the macular region. The interval between the onset and surgery was also determined. We examined the external limiting membrane (ELM) after surgery and the continuity of the inner segment-outer segment junction (IS/OS junction) of the photoreceptor layer. Results . Impairment of visual acuity was observed when ...

    7. The correlation between rat retinal nerve fiber layer thickness around optic disc by using optical coherence tomography and histological measurements

      The correlation between rat retinal nerve fiber layer thickness around optic disc by using optical coherence tomography and histological measurements

      AIM :To explore the correlation between the retinal nerve fiber layer (RNFL) thickness by using optical coherence tomography (OCT) and by histological measurements in normal adult rats and optic nerve transected rats. METHODS: The RNFL thickness of 36 rats was scanned in a circle 3.46mm far from the optic disc by OCT. The two experimental groups were the normal group ( n =20 rats) and the optic nerve transected group ( n =16 rats). The latter group included 4 groups ( n =4/group) surviving for 1 day, 3, 5 and 7 days. Then the RNFL thickness of the same retina area ...

    9. Performance of Optical Coherence Tomography for Distinguishing between Normal Eyes, Glaucoma Suspect and Glaucomatous Eyes

      Performance of Optical Coherence Tomography for Distinguishing between Normal Eyes, Glaucoma Suspect and Glaucomatous Eyes

      Objective : Evaluate the diagnostic performance of spectral-domain optical coherence tomography (OCT) parameters to distinguish between healthy, glaucoma suspect, and glaucomatous eyes. Material and Method : Forty-eight eyes of glaucoma, 48 glaucoma suspect eyes, and 35 healthy eyes were included. The circumpapillary and macular retinal nerve fiber layer (RNFL) thickness were measured using the CirrusTM OCT (Carl Zeiss Meditec, Inc., Dublin, CA, USA). One-way analysis of variance was used to compare the different parameters among groups. Calculating areas under receiver operating characteristic (AROC) curves evaluated the discriminating power of each parameter. Results : The average circumpapillary RNFL thickness in normal, glaucoma suspects, and ...

    13. Morphological patterns of indirect choroidal rupture on spectral domain optical coherence tomography

      Morphological patterns of indirect choroidal rupture on spectral domain optical coherence tomography

      Purpose: To evaluate the morphological types of indirect choroidal rupture (ICR) using spectral domain optical coherence tomography (SD-OCT). Methods: This was a prospective interventional study of 18 eyes of 18 patients who presented with a history of blunt ocular trauma resulting in choroidal rupture. All patients underwent detailed ophthalmic evaluation and SD-OCT examination. Results: Mean age of the patients was 32±9.6 years. Morphologically, two types of choroidal rupture were seen on SD-OCT. The first type seen (Type 1 ICR) was a forward protrusion of the retinal pigment epithelium-choriocapillaris (RPE-CC) layer with an acutely angled pyramid or dome shape ...
