PURPOSE: To analyze the potential benefit of newly developed Tomography and Biomechanical Index (TBI) for early keratoconus screening. METHODS: In this retrospective study, discriminatory power corneal tomography Belin/Ambrósio Enhanced Ectasia Display (BAD-D) index Corvis (CBI) TBI to differentiate between normal eyes, manifest eyes (KCE), very asymmetric with ectasia (VAE-E), their fellow either regular topography (VAE-NT) or (VAE-NTT) were analyzed by applying t test (for distribution),...
To improve keratoconus (KC) screening with new in vivo biomechanical Scheimpflug analyses.After adjusting for intraocular pressure and corneal thickness, predefined static dynamic curve analyses [Pentacam HR Corvis ST (CST); Oculus] of 87 normal eyes, 27 subclinical KC 42 suspected KC, 65 manifest eyes were reviewed retrospectively. A t test (for a distribution), Wilcoxon matched-pairs (if not normally distributed), receiver operating characteristics used to statistically significant...

Three subgroups defined by magnitude (0.25, 0.50, D) were formed. Manifest refraction, uncorrected corrected acuity...
To investigate the influence of lag time between onset central visual acuity loss and surgical intervention macula-off retinal detachment.This retrospective case series examined all consecutively treated eyes with primary detachment at University Hospital Hamburg (Germany) from February 2010 to 2015. Records 1727 patients operated by six surgeons were reviewed. Eighty-nine (5.2%) 89 met inclusion exclusion criteria. The main outcome measure studied was final as a function symptom duration...
To evaluate anterior and posterior changes in corneal topography tomography after crosslinking (CXL) eyes with progressive keratoconus.Scheimpflug analyses (Pentacam, Oculus) of 20 keratoconus performed before CXL were included into retrospective analysis. Mean follow-up was 2 years. Changes topographic, tomographic, pachymetric values statistically analyzed applying analysis variance. Further, the distance direction between maximum keratometry (K(max)) apex as well thinnest point thickness...
Purpose To examine the prevalence and associations of anisometropia with spherical ametropia, cylindrical power, age, sex. Methods Anisometropia was analyzed for subjective refraction. In total, 134,603 refractive surgery candidates were included in period from 2010 to 2020 at CARE Vision Refractive Centers Germany. Our study approved by local ethics committee University Duesseldorf (approval date: February 9, 2021) conducted according tenets Declaration Helsinki Good Clinical Practices...
Abstract Purpose This study aims to analyze the vision-related quality of life (vr-QoL) in keratoconus (KC) patients after corneal crosslinking (CXL). Methods A prospective clinical was conducted, wherein 41 underwent assessment using "National Eye Institute Visual Functioning Questionnaire" (NEI-25) and "Keratoconus Outcomes Research (KORQ) evaluate vr-QoL, along with examination morphology functional parameters before CXL, at three six months post-treatment. Rasch analyses were used verify...
Background: Red eye can arise as a manifestation of many different systemic and ophthalmological diseases.The physician whom the patient first consults for this problem is often not an ophthalmologist.A correct assessment urgency situation vitally important planning further diagnostic evaluation treatment.Methods: This review based on pertinent publications retrieved by selective literature search in PubMed August 2016 well authors' own clinical scientific experience.Results: Primary care...
To analyse tomographic changes in eyes classified as 'normal', 'keratoconus-suspect' and 'clinically manifest keratoconus' based on the established KISA% definition of Rabinowitz Rasheed to develop category 'subclinical keratoconus eyes' expand classification into a 'subtopographic' range.Tomographic topographic analyses 670 performed with rotating Scheimpflug imaging system (Pentacam(®), Oculus Inc., Wetzlar, Germany) were retrospectively analysed. Based system, assigned or 'manifest group....
Purpose To prospectively assess the effect of a single and regular application either cationic nanoemulsion mineral oil (CN) or perfluorohexyloctane (F6H8) on lipid layer tear film higher order aberrations (HOA) in patients with Dry Eye Disease (DED). Methods Fifty-seven thickness (LLT) ≤ 75 interferometric colour units (ICU) were included study. In group A (20 patients) drop F6H8 CN HOA LLT was assessed immediately after up to two hours later. For long term effects (Group B) 37 applied five...
To analyze the influence of demographic and ocular factors on residual astigmatism (ORA) in myopic laser situ keratomileusis (LASIK).University Medical Center Hamburg-Eppendorf, Hamburg, Germany.Retrospective cross-sectional data analysis.Eyes consecutive patients scheduled for LASIK were studied to evaluate preexisting ORA age, sex, dominance, subjective cylinder topographic astigmatism, sphere, mesopic pupil size. The was determined using Alpins vector analysis. Two subgroups, defined by...
Purpose To examine the refractive and visual outcomes of wavefront-optimized laser in situ keratomileusis (LASIK) myopic eyes with low astigmatism 0.75 diopter (D) or less. Setting University Medical Center Hamburg-Eppendorf, Germany, Care Vision private clinics, Germany Austria. Design Retrospective cross-sectional data analysis. Methods This study comprised consecutive patients a preoperative cylinder D less subjective sphere between −2.75 −11.50 D. Three subgroups were formed based on...
To discriminate between subclinical fellow eyes of patients with keratoconus (scKCE) and normal (NE) using swept-source Fourier-domain anterior segment optical coherence tomography (SS-OCT).University Medical Center Hamburg-Eppendorf, Germany.Retrospective cross-sectional study.NE (both a KISA% Index <60; N = 213) scKCE (KISA% <60, but an index >100 in the eye; 61) were grouped according to Index. Topography data obtained by SS-OCT (Casia SS1000) reviewed retrospectively. Receiver operating...
