Motion-Acuity Test for Visual Field Acuity Measurement with Motion-Defined Shapes.

The standard visual acuity measurements rely on stationary stimuli, either letters (Snellen charts), vertical lines (vernier acuity) or grating charts, processed by those regions of the visual system most sensitive to the stationary stimulation, receiving visual input from the central part of the visual field. Here, an acuity measurement is proposed based on discrimination of simple shapes, that are defined by motion of the dots in the random dot kinematograms (RDK) processed by visual regions sensitive to motion stimulation and receiving input also from the peripheral visual field. In the motion-acuity test, participants are asked to distinguish between a circle and an ellipse, with matching surfaces, built from RDKs, and separated from the background RDK either by coherence, direction, or velocity of dots.

Canaloplasty - Efficacy and Safety in an 18-Month Follow Up Period, and Analysis of Outcomes in Primary Open Angle Glaucoma Pigmentary Glaucoma and Pseudoexfoliative Glaucoma.

Purpose: Open-angle glaucoma (OAG), accounting for 90% of all glaucoma cases, is a progressive optic nerve neuropathy. It may lead to irreversible loss of visual field and complete blindness. When conservative treatment becomes insufficient to stop OAG progression, a surgical intervention is considered.

Motion-Based Acuity Task: Full Visual Field Measurement of Shape and Motion Perception.

Purpose: Damage of retinal representation of the visual field affects its local features and the spared, unaffected parts. Measurements of visual deficiencies in ophthalmological patients are separated for central (shape) or peripheral (motion and space perception) properties, and acuity tasks rely on stationary stimuli. We explored the benefit of measuring shape and motion perception simultaneously using a new motion-based acuity task.

[A review of safety and efficacy of levofloxacin 0.5% ophthalmic solution in the treatment of external ocular infections and in prophylaxis of postoperative endophthalmitis].

Levofloxacin 0.5% ophthalmic solution is a fluoroquinolone antibacterial agent with a broad spectrum of activity against Gram positive and negative bacteria. For those reasons it is highly effective in treating common external infections of the eye including blepharitis, conjunctivitis, keratitis.

Comparison of the biometric measurements obtained using noncontact optical biometers LenStar LS 900 and IOL Master V.5.

Purpose: Evaluation of the measurement accuracy using a new optical biometer LenStar LS 900 (Haag Strait) and comparison according to the IOL Master V.5 (Zeiss) device.

Methods: In a prospective clinical study biometric measurements along with artificial lens power calculation using the LenStar LS 900 device were performed.
