Purpose
The VISIONARY study assessed, in a real-world clinical practice setting, the efficacy of preservative-free tafluprost/timolol fixed-dose combination (PF tafluprost/timolol FC) in adults with open-angle glaucoma (OAG) or ocular hypertension (OHT) who did not achieve an adequate response to initial prostaglandin (PGA) or beta-blocker (BB) mon...
Introduction:
In the last 25 years, topical prostaglandin analogues (PGAs) have emerged to become first line and first choice therapeutic options in the management of glaucoma and ocular hypertension (OHT). Although the short-term efficacy and safety of PGAs has been extensively investigated, less is known about their long term safety and tolerabi...
Background: In ophthalmology, thickness and vessel density (VD) measurements for the 6 x 6 mm inner macular retinal area have received increasing attention in glaucomatous progression research. For this area, the Angiovue optical coherence tomography system introduced a 304 x 304 A/B scans function (classic Angio Retina scan) in 2014, and a 400 x 4...
We report 2 peripapillary pit cases, in which the isolated visual field defects spatially correspond to the pit-related retinal nerve fiber layer and optical coherence tomography (OCT) angiography (OCTA) perfusion damage areas.

In the last years optical coherence tomography imaging of the optic nerve head and the peripapillary retina became a part of the routine clinical practice worldwide. Unfortunately, performing optic nerve head imaging routinely does not mean that all acquired images are technically correct and clinically informative. Imaging artifacts are common, an...

Cystoid macular edema (CME) is a form of macular retina thickening that is characterized by the appearance of cystic fluid-filled intraretinal spaces. It has classically been diagnosed upon investigation after a decrease in visual acuity; however, improvements in imaging technology make it possible to non-invasively detect CME even prior to a clini...

The present review casts a critical eye on intraocular pressure (IOP) monitoring and its value in current and future glaucoma care. Crucially, IOP is not fixed, but varies considerably during the 24-h cycle and between one visit and another. Consequently, a single IOP measurement during so-called office hours is insufficient to characterize the rea...
Optical coherence tomography angiography (OCTA) comprises different OCT-based technologies developed for non-invasive assessment and measurement of optic nerve head and retinal perfusion. Currently the most clinically established approach is based on the split spectrum amplitude decorrelation algorithm, which detects moving red blood cells and elim...

Exfoliation syndrome (XFS) is a genetically determined systemic condition characterized by the production and accumulation of an abnormal protein, the exfoliative material. Though XFS is a systemic elastosis, the most significant clinical consequences occur in the eye (nuclear cataract formation, Zinn’s zonule fragility, increased risk for cataract...
Background/purpose:
Using adaptive bracketing "normal" (N) strategy it has been shown that cluster trend analysis is useful for early detection of glaucomatous progression with Octopus perimetry. However, in clinical practice "tendency-oriented perimetry" (TOP) is mostly used. In TOP, responses given at neighboring points modify the threshold valu...
Introduction:
Medical therapy of glaucoma aims to maintain the patient's visual function and quality of life. This generally commences with monotherapy, but it is often difficult to reach the predetermined target pressure with this approach. Fixed combinations (FCs) are therefore selected as the next step of the medical therapy algorithm. By emplo...

Myelinated retinal nerve fibers (MRNF) represent an asymptomatic developmental anomaly in which myelin sheaths extend to a group of retinal nerve fibers along their intraocular portion. The additional volume of the myelin sheaths causes displacement of the axons toward the vitreous body. We investigated the effect of localized MRNF on peripapillary...

Carbonic anhydrase inhibitors are IOP-lowering sulfonamide derivatives which inhibit the activity of CA in the ciliary processes of the eye, thus reducing aqueous humor formation and consequently decreasing IOP. Systemic CAIs provide an approximately 40% IOP reduction, and their effect develops rapidly. Therefore, systemic CAIs (most frequently ace...

Exfoliative glaucoma is the most common type of secondary open-angle glaucoma worldwide. It is characterized by high intraocular pressure (IOP) and worse 24-hour IOP characteristics. In order to minimize progression, treatment of exfoliative glaucoma has to provide a low long-term mean IOP and good 24-hour IOP control. To achieve these goals, fixed...

Fixed-dose c...
Abstract We investigated the intraocular pressure (IOP) lowering efficacy of preservative-free fixed and non-fixed combination of tafluprost 0.0015% and timolol 0.5% in pseudoexfoliative glaucoma (XFG). A per protocol worse eye analysis was made on all XFG patients who participated in a recent 6-month, prospective, randomised, double-masked, parall...
Exfoliation syndrome (XFS) is a systemic condition. Intraocular alterations represent only a part of the exfoliation-related clinical signs. Exfoliation material has been identified in the visceral organs, skin, and vessel walls. This triggered several studies that investigated association between XFS and cardiovascular diseases. In many population...

Now, we reevaluated the influence of AMD on GCC image segmentation and classification for glaucoma on the...
Introduction:
Several large, randomized, prospective clinical trials have demonstrated that medical therapy to reduce intraocular pressure (IOP) delays the onset and decreases progression of glaucoma. Many patients with glaucoma require more than one ocular hypotensive medication to achieve and maintain their target IOP; however, use of multiple t...
