20080231808	Relaxed confocal catadioptric scanning laser ophthalmoscope - A number of additional embodiments and optical constructions of a relaxed confocal catadioptric scanning laser ophthalmoscope (SLO) are disclosed. They improve the functionality of microperimetry (MP), and the integration of the existing instrument with the capabilities of high speed Fourier domain optical coherence tomography (SD-OCT/SS-OCT). The improvements pertain to enhanced acousto-optic modulation with regard to rise-time and combination of wavelengths, enhanced control of illuminating beam characteristics and separation of illuminating and returned light within the SLO, enhanced electronic control and options for the galvanometer and polygon scanners, additional use of liquid crystal spatial light modulation, and the modalities under which Fourier domain OCT can be integrated within the SLO.	09-25-2008
20100290007	Electronic ophthalmoscope for selective retinal photodisruption of the photoreceptor mosaic - An electronic ophthalmoscope combining scanning laser (SLO) and optical coherence (OCT) technologies is further equipped with a pulsed laser source in the femtosecond (fs) range. The goal is primarily to selectively disrupt the photoreceptor mosaic of the retina or Bruch's membrane in a pattern that minimizes loss of visual functioning, and to reduce thereby the metabolic load of the outer retina. Using a beam splitter, one embodiment combines the SLO scanning beams with the therapeutic laser beam and aiming beam. The therapeutic channel uses an independent x/y positioner and micro-deflector. Because the duty cycle is appropriate, a second embodiment can use the SLO scanners to also scan a modulated therapeutic laser beam. A biometric OCT probe, helpful in focusing, can be integrated in both configurations. A method is also disclosed to represent the tilting of the retina at a specified location.	11-18-2010
20140371731	ELECTRONIC OPHTHALMOSCOPE FOR SELECTIVE RETINAL PHOTODISRUPTION OF THE PHOTORECEPTOR MOSAIC - An electronic SLO/OCT ophthalmoscope is equipped with a femtosecond (fs) laser for intra- or preretinal therapeutic use in the posterior segment of the eye. In one application the retina photoreceptor mosaic or Bruch's membrane is disrupted in such pattern that minimizes loss of visual functioning but reduces metabolic load of the outer retina. Using a beam splitter, one embodiment combines the SLO/OCT scanning beams with the therapeutic fs beam and an aiming beam. The therapeutic channel uses an independent x/y positioner and micro-deflector. Because the duty cycle is appropriate, a second embodiment can use the SLO/OCT scanners to also simultaneously scan a modulated therapeutic laser beam. A biometric OCT probe can be integrated in both configurations for focusing purpose. A method is disclosed to represent focus relevant tilting of the retina in the posterior pole. A derived apodizing “Stiles-Crawford” pupil weighting function is also independently useful for calculating light efficiency throughput of the anterior eye optics (cornea and iol/natural lens) in various circumstances.	12-18-2014

20130183357	OXIDATIVELY CROSS-LINKED PROTEIN-BASED ENCAPSULATES - The present invention provides a method of producing a protein-based encapsulate, said method comprising: providing an aqueous solution of a protein that is capable of forming disulfide cross-links; submitting said aqueous solution to a protein activation treatment to produce an aqueous suspension of activated protein aggregates, said suspension having a reactivity of at least 5.0 μmol thiol groups per gram of activated protein aggregates as determined in the Ellman's assay; dispensing said aqueous suspension in a gas or a water-immiscible liquid to produce suspension droplets having a diameter of 0.1-500 μm; and forming disulfide cross-links between the activated protein aggregates by contacting the activated protein aggregates with an oxidizing agent, optionally after said activated protein aggregates have been partially cross-linked by forming disulfide cross-links by means of heat treatment or by pressurization to a pressure in excess of 50 MPa. The aforementioned method offers the advantage that the characteristics of the protein-based encapsulation matrix can be controlled effectively. Furthermore, said method enables the preparation of protein-based encapsulates that very effectively protect the encapsulated components, e.g. against oxidation or moisture.	07-18-2013
