Variations of OCT measurements corrected for the magnification effect according to axial length and refractive error in children
2018
Purpose: The aim of this paper was to examine the distribution of macular, retinal nerve fiber layer (RNFL) thickness and optic disc parameters of myopic and hyperopic eyes in comparison with emmetropic control eyes and to investigate their variation according to axial length (AL) and spherical equivalent (SE) in healthy children. Methods: This study included 293 pairs of eyes of 293 children (145 boys and 148 girls), ranging in age from 6 to 17 years. Subjects were divided according to SE in control (emmetropia, 99 children), myopia (100 children) and hyperopia (94 children) groups and according to axial AL in 68 short ([Formula: see text]22.00[Formula: see text]mm, 68), medium (from [For…
Arteriovenöse Dissektion (AVD) bei retinalen Venolenastverschlüssen
2009
BACKGROUND: The aim of this study is to report on arteriovenous sheathotomy in branch retinal vein occlusion (BRVO) with a long-term follow-up and examine the visual field effects of this surgical approach. PATIENTS AND METHODS: In a clinical trial 36 eyes with branch retinal vein occlusion (22 eyes with ischaemia, 14 eyes with chronic macular oedema) underwent surgical decompression accompanied by peeling of the membrana limitans interna after prior isovolemic haemodilution for 3 months had been unsuccessfull. RESULTS: All eyes showed a significant reduction of macular oedema 3 months after surgery. During follow-up (median: 26.4 months) visual acuity increased in 24 / 36 eyes and was stab…
Safety and Efficacy of Ranibizumab in Macular Edema following Retinal Vein Occlusion.
2013
Macular edema is the leading cause of visual impairment in patients with retinal vein occlusion. Limited improvements may be obtained with laser photocoagulation or intravitreal triamcinolone. However, according to the data provided by randomized clinical trials, intravitreal injections of ranibizumab (Lucentis; Genentech, South San Francisco, CA) constitute a new effective and safe option for the management of these vision-threatening diseases. The aim of the present review is to summarize the clinical evidence of ranibizumab for macular edema due to retinal vein occlusions.
Serous Macular Detachment Associated with Dome-Shaped Macula and Tilted Disc
2011
Introduction: An entirely new type of staphyloma has been recently described as dome-shaped macula (DSM). It is characterized by an abnormal convex macular contour within the concavity of a posterior staphyloma. We found DSM associated with serous macular detachment (SMD) and tilted disc in two consecutive cases. Case Reports: Case 1: A 37-year-old female presented to our department because of sudden onset blurred vision in her right eye (OD). The best-corrected visual acuity (BCVA) was 0.5 in both eyes. Funduscopy evidenced bilateral tilted disc associated with posterior staphyloma. Optical coherence tomography (OCT) demonstrated a DSM with SMD in her OD. After 15 months of follow-up, BCVA…
Radiation effects on light scattering and cataract formation in the lenses of interventional radiologist and cardiologists
2014
Purpose There is little information about exposure to dosages below 500 mSv. This pilot study aimed at investigating the effects of low dose radiation on lens transparency in occupationally exposed interventional cardiologists and radiologists. Methods Physicians who have performed fluoroscopically guided procedures for at least 5 years were recruited in the areas of Cologne-Bonn and Rhine-Main together with their non-exposed colleagues. A questionnaire has been developed to estimate occupational exposure. Exclusion criteria comprised corticosteroid treatment, radiotherapy, chemotherapy and glaucoma. Changes in lens transparency and cataract formation were determined by slit lamp microscopy…
Propeller Flaps in the Head and Neck
2020
AbstractPropeller flaps have significantly expanded the reconstruction possibilities in the head and neck region. They allow for increased flap mobility and better scar concealing, and/or to perform a one-stage reconstruction with local tissue of similar color and texture, where multiple surgeries would be needed with traditional flaps or even free flaps would be required. This article describes the main propeller flaps for one-stage reconstruction in the head–neck region (facial artery perforator, supratrochlear artery axial perforator, deep lingual artery axial perforator, and anterior supraclavicular artery perforator flaps), their indications, and possible complications. Aesthetic and f…
Metabolic adaptation and neuroprotection differ in the retina and choroid in a piglet model of acute postnatal hypoxia.
2013
Hypoxic-ischemic insults to the neonatal brain may cause neurodevelopmental disorders. Vulnerability of different areas of the neural tissue to hypoxic-ischemic stress might be explained by either heterogeneous sensitivity to oxygen or neuroprotective capability. Our understanding of regional heterogeneity is still incomplete in terms of metabolic reconfiguration and/or activation of neuroprotective mechanisms.We studied, by western blotting, reverse-transcriptase PCR, and tandem mass spectrometry, the response of retina and choroid at protein, gene, and metabolic levels during hypoxia in a piglet model of acute postnatal hypoxia.We evidenced a metabolic shift towards glycolysis in choroid …
Dental considerations for the patient with renal disease
2011
Chronic renal disease (CRD) is the renal disease that manifests oral consequences most frequently, and it is defined as a progressive and irreversible decline in renal function associated with a reduced glomerular filtration rate (GFR). The most frequent causes of CRD are diabetes mellitus, arterial hypertension and glomerulonephritis. CRD is classified in 5 stages – from kidney damage with normal or increased GFR to renal failure. In order to quantify the CRD, renal function is measured using the GFR, which is estimated using creatinine clearance (CC). This CC is used for dose adjustment of drugs. In dental practice, the function of the kidneys can be measured indirectly through plasmatic …
Morbus Eales – 10 Jahre Erfahrung mit einem seltenen Krankheitsbild
2009
BACKGROUND: Eales’ disease is an uncommon vasoproliferative retinal disease affecting otherwise healthy young men. We report on our treatment results in a large patients group with long-term follow-up. PATIENTS AND METHODS: The treatment results in 50 eyes (35 patients) with Eales’ disease, that were cosecutively treated from May 1995 to August 2005, were analysed retrospectively. Recorded data included age, sex, race, association of systemic disease, medications, laboratory evaluation and the surgical treatment. Mean follow-up was 5.8 years (minimum: 3.2, maximum: 8.6 years). RESULTS: Systemic and laboratory evaluations detected a factor V Leiden mutation (4 × ), vestibuloauditory problems…
