All rights reserved.Purpose: To evaluate effect of age, sex and axial length on photoreceptor layer (PRL), retina pigment epithelium layer (RPEL) and choroid layer (CL) thicknesses in a population of healthy eyes, using spectral-domain optical coherence tomography (SD-OCT). Material and Methods: Seventy-one subjects with an age ranging between 16 and 65 years were examined with SD-OCT. Mean PRL, RPEL and CL thicknesses were measured at the fovea and 500 ?m, 1000 ?m, 2000 ?m distances from the fovea at nasal and temporal quadrants. Choroidal thickness was manually measured from the posterior edge of the retinal pigment epithelium to the choroid-scleral junction. Results: Fourty-six (64.8%) of the patients were women, 25 (35.2%) were men. The mean age of the participants was 43.07±13.56 years (range, 16-65 years). The mean axial length was 23.28±0.74 mm (range, 21.18-24.76 mm). Macular PRL, RPEL and CL thicknesses showed no significant variations by sex, age, spherical equivalent and axial length (p>0.05). There were a statistically significant correlation between PRL and RPEL thicknesses at all quadrants. Conclusion: Photoreceptor layer, RPEL and choroidal thicknesses had no significant correlation with age, sex and axial length. Prosepective studies with larger sample size are needed to assess the correlation between choroidal thickness and outer retinal layers. more...

Objectives: To investigate the effect of pupillary dilation on peripapillary enal nerve fiber layer (RNFL) thickness measurements taken by spectral-domain optical coherence tomography (SD-OCE).

WOS: 000429421300003 PubMed ID: 29576891 Objectives: To assess the visual outcomes in patients who underwent cataract surgery with multifocal intraocular lens (IOL) implantation using a "mix and match" approach. Materials and Methods: Twenty patients (40 eyes) were involved in this prospective, nonrandomized study. Refractive multifocal IOLs (ReZoom NXG1) were implanted in patients' dominant eyes and diffractive multifocal IOLs (Tecnis ZMA00) were implanted in their non-dominant eyes. Monocular and binocular uncorrected distance, intermediate and near visual acuity (logMAR), and contrast sensitivity levels were measured at 1, 3, and 6 months after cataract surgery. Defocus curves, reading speeds, patient satisfaction, spectacle dependence, and halo and glare symptoms were also evaluated at 6 months after the surgery. Postoperative quality of life was assessed with the Turkish version of National Eye Institute Visual Function Questionnaire-25. Results: The study group comprised 8 females and 12 males with a mean age of 69.45 +/- 10.76 years (range, 31-86 years). The uncorrected distance and intermediate visual acuity levels were significantly better in the ReZoom-implanted eyes at postoperative 6 months (p = 0.026 and p = 0.037, respectively). There was no statistically significant difference in uncorrected near visual acuity (p > 0.05). There was no statistically significant difference in contrast sensitivity, reading speed, halos, or glare between the groups (p < 0.05). Mild glare/halo was reported by 40% of the subjects. The mean patient satisfaction was 95% and all patients were spectacle independent. Conclusion: Mixing and matching multifocal IOLs in selected cataract patients provides excellent visual outcome, a high level of patient satisfaction, and spectacle independency.
