    1. The role of Müller cells in tractional macular disorders: an optical coherence tomography study and physical model of mechanical force transmission

      The role of Müller cells in tractional macular disorders: an optical coherence tomography study and physical model of mechanical force transmission

      Background To explore the role of foveal and parafoveal Müller cells in the morphology and pathophysiology of tractional macular disorders with a mathematical model of mechanical force transmission. Methods In this retrospective observational study, spectral-domain optical coherence tomography images of tractional lamellar macular holes and patients with myopic foveoschisis were reviewed and analysed with a mathematical model of force transmission. Parafoveal z-shaped Müller cells were modelled as a structure composed of three rigid rods, named R1, R2 and R3. The angle formed between the rods was referred to as θ . R1, R2 and R3 lengths as well as the ...

    2. Prevalence of Vitreoretinal Interface Abnormalities on Spectral-Domain Optical Coherence Tomography in Healthy Participants over 45 Years of Age

      Prevalence of Vitreoretinal Interface Abnormalities on Spectral-Domain Optical Coherence Tomography in Healthy Participants over 45 Years of Age

      Purpose To assess the prevalence of vitreoretinal interface abnormalities in a general population of healthy adults ≥45 years of age. Design Cross-sectional study carried out at 17 ophthalmology services throughout Spain. Participants Between September 2015 and March 2016, all consecutive healthy persons aged ≥45 years who were accompanying patients to ophthalmology services were invited to take part in the study. Exclusion criteria were known retinal disease, uveitis, history of ocular trauma or previous intraocular surgery (including cataract surgery and intravitreal injections), severe myopia (>−6 dioptres), and poor ocular media transparency. Methods Spectral-domain optical coherence tomography (OCT) or swept-source OCT was ...

    3. Insights into epiretinal membranes: presence of ectopic inner foveal layers and a new optical coherence tomography staging scheme

      Insights into epiretinal membranes: presence of ectopic inner foveal layers and a new optical coherence tomography staging scheme

      Abstract Purpose To describe the presence of continuous ectopic inner foveal layers associated with epiretinal membranes (ERMs) and to present a new optical coherence tomography (OCT) staging system of ERMs. Design Retrospective multicenter observational case series. Methods Clinical charts and Spectral-Domain OCT images of 194 eyes of 172 consecutive patients diagnosed with ERMs were reviewed and analyzed. Results The presence of continuous ectopic inner foveal layers was identified in 63 out of 194 eyes (32.5%) and this morphology was significantly associated with lower visual acuity. ERMs were divided in four stages. Stage 1 (43 out of 194 eyes, 22 ...

    4. Macular structure on optical coherence tomography after lamellar macular hole surgery and its correlation with visual outcome

      Macular structure on optical coherence tomography after lamellar macular hole surgery and its correlation with visual outcome
      Objective To report macular structure on optical coherence tomography (OCT) after lamellar macular hole surgery and its relationship with visual outcome. Design Retrospective interventional case series; private practice setting. Participants Twelve patients diagnosed with a lamellar hole who had undergone vitrectomy and who had OCT scanning before and after surgery and at least 6 months follow-up were included. Methods Surgery consisted of 25 g vitrectomy, peeling of epiretinal and internal limiting membrane, fluid/air/gas exchange, and 2 weeks of face-down positioning. Results OCT showed an epiretinal membrane in all cases. After a mean follow-up of 16.7 months, VA ...
