Purpose: To determine if early central corneal thickness (CCT) and best-corrected visual acuity (BCVA) changes indicate graft detachment after uncomplicated Descemet membrane endothelial keratoplasty (DMEK).
Methods: In this analysis of our prospectively collected ADDA registry data ( https://drks.de/search/de/trial/DRKS00027180 ), 45 pseudophakic eyes underwent DMEK surgery at the Department of Ophthalmology, RWTH Aachen University.
Background: Trabeculotomy with the Kahook knife is a new ab interno minimally invasive glaucoma surgery (MIGS) procedure. The MIGS are usually performed in early to intermediate glaucoma eyes. In this retrospective study we analyzed the intraocular pressure (IOP) and topical glaucoma eye drop therapy (Meds) reduction achieved by the Kahook trabeculotomy (TO) without (n = 19) or with (n = 18) combined cataract operation (Cat-TO) as initial treatment before or to avoid filtering surgery.

Further sub-analysis was performed to compare between 90 and 120 degrees goniotomy.
Methods: This was a prospective case series of 69 eyes from 69 adults (age 78 ± 5.
Background: The Masterplan Medicine 2020 has been passed by German authorities in 2017 and will be the basis for future developments in teaching and medical education in Germany. The "Nationaler Kompetenzbasierter Lernzielkatalog" NKLM as a learning target index will be the substructure in terms of its content.
Method: The NKLM 2.
Purpose: Single-use dual blade goniotomy (SBG) is a novel ab interno procedure that removes three to five clock hours of trabecular meshwork (TM). We analysed the reduction of intraocular pressure (IOP) and topical glaucoma medication (Meds) in eyes following combined cataract surgery and SBG (Cat-SBG).
Methods: IOP and Meds were evaluated retrospectively in 55 eyes of 38 patients.
Background/aims: Glaucoma is a chronic disease that requires lifelong monitoring and treatment. However, its control is limited due to discontinuous intraocular pressure (IOP) monitoring related to the practitioners' office hours. Implantable telemetric IOP sensors have made self-measurements possible and provide important information regarding the IOP profiles of patients.

At the age of 6 weeks, an uncomplicated 360° trabeculotomy had been performed, which resulted in intraocular pressure (IOP) control for only 4 months. The gel stent implantation was performed ab interno without complications.

Purpose: To investigate the relationship of ocular blood flow (via arteriovenous passage time, AVP) and contrast sensitivity (CS) in healthy as well as normal tension glaucoma (NTG) subjects.
Design: Mono-center comparative prospective trial METHODS: Twenty-five NTG patients without medication and 25 healthy test participants were recruited. AVP as a measure of retinal blood flow was recorded via fluorescein angiography after CS measurement using digital image analysis.
Purpose: Vascular risk factors and ocular perfusion are heatedly discussed in the pathogenesis of glaucoma. The retinal vessel analyzer (RVA, IMEDOS Systems, Germany) allows noninvasive measurement of retinal vessel regulation. Significant differences especially in the veins between healthy subjects and patients suffering from glaucoma were previously reported.

Purpose: To determine retinal thickness (RT) changes and the incidence of macular edema after uncomplicated Descemet membrane endothelial keratoplasty (DMEK-ME) in patients without ME risk factors.
Methods: In this retrospective study, 107 pseudophakic eyes of 74 patients with Fuchs endothelial dystrophy (FED) (79.4%) or bullous keratopathy (BK) (20.
Purpose: We assessed the accuracy of lens power calculation in highly myopic patients implanting plus and minus intraocular lenses (IOL).
Methods: We included 58 consecutive, myopic eyes with an axial length (AL) > 26.0 mm, undergoing phacoemulsification and IOL implantation following biometry using the IOLMaster 500.
Intraocular infections associated with Abiotrophia defectiva are rare. This article reports the case of a 57-year-old woman with endophthalmitis associated with Abiotrophia defectiva 3 months after uncomplicated cataract surgery combined with the implantation of a glaucoma gel-stent in the right eye. The patient had complained of redness of the right upper nasal conjunctiva and pain for 2 weeks prior to the endophthalmitis.

Objective: The aim of this retrospective case series was to compare the long-term success of CP and TE under the same conditions and with the same levels of experience of the surgeon as well as to investigate whether preoperative intraocular pressure (IOP) and postoperative IOP correlate with eachother.
Methods: The study included 57 eyes that underwent either CP or TE (CP n = 27; male = 50.

Purpose: Nonperfusion of retinal tissue due to arterial occlusion leads inevitably to mostly irreversible retinal damage. Until today no evidence-based treatment exists. Inhalation of 100% oxygen at high atmospheric pressure causes an increased solubility of oxygen in the blood that helps the retinal tissue to survive through diffusion in case of an artery occlusion till vascular recanalization occurs.

The first measure is the elaboration of a learning target index of the German Ophthalmological Society (DOG).
Method: The masterplan medicine 2020 has been passed by German authorities in 2017 to restructure studies in human medicine at German universities according to a concept of skill-related learning objectives rather than based on factual knowledge.

Purpose: Most studies about retinal detachment cover a limited follow-up period. The purpose of this research is to assess the long-term results after pars plana vitrectomy (PPV) and scleral buckle (SB) surgery in patients with rhegmatogenous retinal detachment (RRD).
Methods: 155 patients with RRD are treated either with SB or PPV with a mean follow-up of more than 5 years.
Purpose: Reliable and regular assessment of intraocular pressure (IOP) is important for the monitoring of patients with glaucoma. The purpose of this study was to evaluate the feasibility of a novel system for the automated, noncontact measurement of IOP.
Patients And Methods: A first-generation telemetric IOP sensor was previously implanted in the ciliary sulcus of six patients with open-angle glaucoma during cataract surgery.
Purpose: The purpose of this study was to evaluate ocular hemodynamics in patients with a disease believed to be related to a chronic vascular damage [ie, normal tension glaucoma (NTG)] in comparison with an entity with an acute ischemic impact on the optic nerve [ie, acute nonarteritic anterior ischemic optic neuropathy (NAION)].
Materials And Methods: Blood-flow velocities [peak systolic velocity (PSV), enddiastolic velocity (EDV)] of the ophthalmic artery (OA), central retinal artery (CRA), and nasal and temporal posterior ciliary arteries were measured using color Doppler imaging. Resistive index (RI) of all vessels was calculated (PSV-EDV/PSV).
Purpose: Vascular dysfunction and ischemia are believed to play an important part in the pathogenesis of glaucoma and especially of normal tension glaucoma (NTG). The aim of the present study was to analyze the blood pressure (BP) and heart rate variability patterns in patients with primary open-angle glaucoma (POAG) and NTG compared with controls.
Methods: In total, 37 patients with POAG, 27 patients with NTG, and 82 control subjects were included in a prospective clinical validation study.
