    1. Visual Outcomes, Visual Fields, and Optical Coherence Tomography in Paediatric Craniopharyngioma

      Visual Outcomes, Visual Fields, and Optical Coherence Tomography in Paediatric Craniopharyngioma

      Ten patients with craniopharyngioma treated for the first time when younger than 18 were included. This study reviews the visual outcomes and provides information on visual field (VF) and optical coherence tomography (OCT) examination of craniopharyngioma. The best kappa concordance coefficients between VF and OCT parameters of atrophy were obtained for the ganglion cell (GC) thickness and the mean retinal nerve fibre layer (RNFL) thickness. The agreement between GC colour maps and VF defects was good. Optic nerve compression may be detected by RNFL measurement and GC analysis, and this may be valuable to predict visual recovery and in uncooperative ...

    2. Retinal Thickness Measured by Spectral-Domain Optical Coherence Tomography in Eyes Without Retinal Abnormalities: The Beaver Dam Eye Study

      Retinal Thickness Measured by Spectral-Domain Optical Coherence Tomography in Eyes Without Retinal Abnormalities: The Beaver Dam Eye Study

      We read with great interest the article by Myers and associates, 1 providing normative values of spectral-domain optical coherence tomography (SD OCT) macular thickness measurements in a large adult cohort without retinal disease, and examining relationships with age, sex, and other ocular and systemic covariates. The authors found that when adjusting for age, men had thicker retinas than women in the Early Treatment of Diabetic Retinopathy Study (ETDRS) center macula subfield (men vs women: 289.5 vs 273.8 μm, P < .001) and inner ring (337.1 vs 332.5 μm, P < .001) but not in the outer ring (290 ...

    3. Multicenter Spanish study of spectral-domain optical coherence tomography in normal children

      Multicenter Spanish study of spectral-domain optical coherence tomography in normal children

      Purpose:  To compile a multicenter normative database of retinal nerve fibre layer (RNFL) and macular thicknesses and macular volume values in healthy Caucasian children 4–17 years using spectral-domain optical coherence tomography (SD-OCT). To analyse variations in the OCT measurements as a function of age, sex, refraction, and axial length (AL). Methods:  An observational, multicenter and cross-sectional study among 301 healthy Caucasian children recruited at three Spanish centres was performed. To compile the database, each child underwent a dilated eye examination and a cycloplegic refraction, five AL measurements (IOL Master; Carl Zeiss Meditec, Dublin, CA, USA), five OCT scans with ...

    4. Clinically Isolated Syndromes Suggestive of Multiple Sclerosis: An Optical Coherence Tomography Study

      Clinically Isolated Syndromes Suggestive of Multiple Sclerosis: An Optical Coherence Tomography Study

      Background Optical coherence tomography (OCT) is a simple, high-resolution technique to quantify the thickness of retinal nerve fiber layer (RNFL), which provides an indirect measurement of axonal damage in multiple sclerosis (MS). This study aimed to evaluate RNFL thickness in patients at presentation with clinically isolated syndromes (CIS) suggestive of MS. Methodology This was a cross-sectional study. Twenty-four patients with CIS suggestive of MS (8 optic neuritis [ON], 6 spinal cord syndromes, 5 brainstem symptoms and 5 with sensory and other syndromes) were prospectively studied. The main outcome evaluated was RNFL thickness at CIS onset. Secondary objectives were to study ...

    5. 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 ...

    6. Optical Coherence Tomography in Multiple Sclerosis and Neuromyelitis Optica: An Update

      Optical Coherence Tomography in Multiple Sclerosis and Neuromyelitis Optica: An Update
      Optical coherence tomography (OCT) uses light interference patterns to produce a cross-sectional image of the retina. It is capable of measuring the unmyelinated axons of the retinal ganglionar cells as they converge on the optic disc. In a disease like multiple sclerosis (MS), in which axonal loss has been identified as an important cause of sustained disability, it may prove an invaluable tool. OCT has demonstrated that axonal loss occurs after each episode of optic neuritis and that the degree of axonal loss is correlated to visual outcomes. Furthermore, axonal loss occurs in MS even in the absence of inflammatory ...

    7. Reproducibility of OCT in children with glaucoma

      Introduction: Optical Coherence Tomography(OCT) has been proven to be a useful clinical tool in the follow-up of adult glaucoma(IOVS2008;49:4886-4892.). Its use in pediatric glaucoma is limited because reproducibility has been assessed only in normal children and on the same visit (AJO,2007;143:484–488). This study's purpose is to evaluate the reproducibility of OCT in children with stable glaucoma in a clinical setting.

    8. Subclinical foveal hypoplasia in normal children detected by OCT

      Introduction: Foveal hypoplasia is usually associated with significant visual dysfunction and an absent foveal reflex on biomicroscopy. Optical coherence tomography(OCT) easily provides accurate images of the foveal anatomy. Among a group of normal children having OCT for the development of a normative database (Arch Ophthalmol 2009;127), we identified a few with underdeveloped foveal architecture despite normal clinical examination. This study's purpose is to characterize the prevalence and features of subclinical foveal hypoplasia in the eyes of normal children.

    9. Ophthalmic Features of Spinocerebellar Ataxia Type

      Background: Patients with spinocerebellar ataxia 7 (SCA7) are known to develop ocular abnormalities. The purpose of this study was to characterize these abnormalities in greater detail and with the aid of newer quantitative technologies. Methods: Seven patients with SCA7 diagnosed by genetic analysis at La Paz Hospital (Madrid, Spain), a country-wide referral center for ataxias, were included in the study. Demographic data and ocular features were recorded from a complete ophthalmologic examination, specular microscopy, corneal topography (Pentacam), and optical coherence tomography (OCT). Results: All 7 patients had decreased visual acuity associated with varying degrees of macular pigmentary changes on ophthalmoscopy ...
