Introduction: Magnetic intraocular foreign bodies can be removed with magnetized disposable forceps. Aim of this study is to compare the forceps magnetizability of different size, form and manufacturer.
Methods: The forceps were magnetized using an established procedure.
Purpose: We evaluated the timing at and extent to which midterm to long-term keratometric changes can occur in year 1 to 7 after corneal collagen cross-linking (CXL) in patients with keratoconus.
Methods: We conducted a subgroup analysis of a retrospective cohort study of all consecutive patients who underwent CXL at our cornea center between 2007 and 2011. The inclusion criteria comprised CXL according to the Dresden protocol and a full set of keratometry parameters collected by Scheimpflug tomography preoperatively and at year 1, 3, 5, and 7 after CXL.
Purpose: An advantage of rebound tonometry (RT) is its ease of use so that it can also be operated by health care technicians. However, the cost of the disposable measuring probes is high and their reuse carries the risk of infection. Therefore, this study aims to objectify the potential risk of bacterial transmission by RT.

Introduction: To evaluate long-term safety and efficacy of corneal collagen cross-linking (CXL) in patients with keratoconus up to 13 years.
Materials And Methods: In this mono-centre exploratory study, we included all consecutive patients who underwent CXL in our cornea centre from 01/01/2007 to 12/30/2011 and met the inclusion criteria. CXL was performed in all patients according to the Dresden protocol.
Purpose: Central serous chorioretinopathy (CSCR) presents itself as a serous detachment of the central neurosensory retina (NR), which may be accompanied by focal detachment of the retinal pigment epithelium (RPE) and changes in the RPE itself. It is often self-limiting; however, if the macular region is affected, visual impairment can be serious. If spontaneous remission does not occur, data on the effectiveness of further treatment options are sparse.

Keratitis can lead to visual impairment and in severe cases with endophthalmitis to enucleation of the affected eye. As microorganisms are becoming more resistant to antibiotic therapy, there is a need for new therapeutic strategies.

Materials And Methods: 15 consecutive patients were included in this study. All patients received an OCTA with a 3 × 3 mm scan of the region of interest with the ZEISS OCT Cirrus 5000 with the AngioPlex module.
Objective: A comparison between automated and manual measurements of a foveal avascular zone in optical coherence tomography angiography (OCTA) in patients with diabetic retinopathy (DR).
Material And Methods: Consecutive patients with non-proliferative DR were included in this study. All patients received an OCTA, with a 3 × 3 mm scan of the macular region taken with the Zeiss OCT CIRRUS 5000 with the AngioPlex module.

Background: Invasive soft tissue infections by are rapidly progressive and potentially life-threatening infectious diseases. These can also affect the eyelid. Aggressive virulence factors and the synthesis of exotoxins can lead to complications, such as periorbital necrotizing fasciitis (PONF) and streptococcal toxic shock syndrome (STSS).
View Article and Find Full Text PDFBackground: The patient's knowledge about their illness, as well as their expectations regarding pre-intervention, consultation and treatment, may differ from the physician's assumptions. Therefore, it is of great importance that the physician can identify misconceptions and missing knowledge and to focus on those points in the preoperative consultation, as well as meeting patient expectations as to the consultation itself. The aim of this study was to identify such expectations and the knowledge gaps of patients scheduled for ophthalmologic treatment.

Design And Methods: Prospective cross-sectional comparative study in 47 eyes of 47 patients. FA was recorded with the Zeiss FF450plusIR camera and OCTA was obtained with the Zeiss Cirrus 5000 equipped with the AngioPlex module.
Objective: To compare typical findings of diabetic retinopathy in optical coherence tomography angiography (OCTA) and fluorescein angiography (FA).
Subjects/methods: 42 patients were enrolled in this study. We performed FA and obtained en face 3 × 3 mm OCTA images of the macular region.
Background: An increased demand for young physicians in Germany is causing increased competition to attract the best minds, even during their undergraduate studies. Therefore, it is the task of the university hospitals to offer their students the best possible courses in order to arouse interest in the relevant subject area. We therefore examined the impact of an ophthalmosurgical wet lab on teaching undergraduate medical students.

A short-term increase in IOP can occur during refractive procedures, vitreoretinal surgery, transillumination, photocoagulation, or cryocoagulation. A porcine eye model was chosen (n = 89) to compile comparable study data and to de termine correlations between the force induced and the resulting intraocular pressure while excluding the effect of surgeons.

Subablative heating of the cornea using an Er : YAG laser or diode laser is an alternative option. Thermal effects and reproducibility of both procedures were investigated.

Background And Objective: New imaging methods provide novel insights into the pathogenesis of acute posterior multifocal placoid pigment epitheliopathy (APMPPE).
Patients And Methods: Four patients (eight eyes) in acute, subacute, and late phases of the disease were analyzed with multi-modal imaging methods including optical coherence tomography angiography (OCTA), structural OCT, fundus photography, and fundus autofluorescence. One patient was observed during the entire disease course.
Retinal artery occlusion (RAO) is the most common primary angiopathy of the retina. With an incidence of 0.01 - 0.

Purpose: For diaphanoscopy or transscleral laser applications, the transmission of the sclera is an essential property. The study aimed to determine the pressure dependent transmission of human sclera from anterior to posterior.
Methods: Pressure dependent transmission measurements were performed by a pressure inducing setup at the range of 60-2058 kPa.
