Definitions
- the invention relates to a device for the treatment and / or diagnosis of eye diseases according to the preamble of claim 1.
- the invention relates to the treatment and / or diagnosis of eye diseases in the field of human or veterinary medicine, in particular the human eye or the mammalian eye.
- the eye is irradiated with laser light by means of a device, the effective energy of which is so low that there is no tissue damage.
- the object of the present invention is therefore to provide a device for the treatment of eye diseases, in particular the human eye, by means of which a versatile, inexpensive and in particular also " side effect-free treatment is possible.
- the main advantage of the invention is that a versatile, inexpensive and above all also side effects free treatment of the eye is made possible.
- the present method opens up new treatment options for diseases for which there has so far been no satisfactory therapy.
- Figure 1 is a schematic representation of the structure of the inventive device for the treatment of eye diseases
- the present device for the treatment of eye diseases essentially consists of an applicator 2 which comprises a laser source (not shown) which generates a laser beam 4.
- the laser beam can be collimated by suitable optics and brought into a punctiform, dashed or oval shape. However, this is not absolutely necessary for the purpose of the invention.
- the intensity and the frequency of the laser beam can be varied, the laser source being controlled via a line 5 from a control unit 3, which can also be conveniently integrated in the housing of the laser source.
- the laser beam is directed onto an eye 1 for treatment.
- the laser source is preferably a laser diode, the wavelength of which is preferably in the near infrared range (in particular between 400-1400 nm, preferably between 780-830 nm).
- the wavelength of which is preferably in the near infrared range (in particular between 400-1400 nm, preferably between 780-830 nm).
- this laser beam 4 is visible, so that the beam guidance can be recognized and is therefore simplified.
- the laser source instead of only one laser source, it is also conceivable to provide a plurality of laser sources in combination, preferably a plurality of laser diodes in combination, which have the same or different wavelengths or the same or different strengths.
- the beams from these laser sources are preferably brought together on the laser beam 4. Between the laser source or the laser sources and the exit point of the beam or beams 4 from the housing 2, one or more light fibers can be provided for guiding the beam. It is of crucial importance that the output power of the laser beam 4 is so weak that it is below the power that would cause tissue damage such as coagulation, ablation or disruption.
- the beam power of the laser beam 4 is preferably below 100 mW, advantageously between 5-30 mW. Laser light of this power stimulates metabolic processes at the cellular level and this has a positive effect on the treatment.
- the laser beam 4 can be modulated both with regard to its frequency and with regard to its amplitude, that is to say its intensity.
- the pulses for modulation can, for example, be sinusoidal, rectangular or triangular.
- the frequency of the beam modulation is usually in the low frequency range.
- the intensity depends on the form of application and depends on the accessibility or depth of the target structure of the eye to be treated.
- the laser beam 4 can be applied selectively or by sweeping over larger areas, transpupillary, scleral, cutaneous, transorbital or transcraneal.
- the distance between the applicator 2 and the eye is preferably about 5-10 mm.
- the beam intensity should in any case be set significantly lower.
- FIG. 2 shows different therapy modes in which the laser beam 4 is directed in a punctiform manner (FIG. 2 ac) or in a line (FIG. 2 dg) onto the eye and its adnexa.
- FIG. 2a shows a transpupillary
- FIG. 2b a transcorneal
- FIG. 2c a transscleral punctiform treatment with a laser beam 4 with the eye 1 open.
- a line-shaped treatment can also be carried out on the open eye, the laser beam 4 being guided circularly in the limbus area (FIG. 2d) or radially to the pupil (FIG. 2e).
- FIG. 2f shows a line-shaped irradiation of the lower ectropionized eyelid with a laser beam.
- FIG. 2g shows another possible type of therapy in which the laser beam 4 is applied in a line to the lower and upper lid of the closed eye.
- the main advantage of the device according to the invention is that it enables simple, inexpensive treatment in many eye diseases. Sterility problems advantageously do not occur. Side effects are when used properly and
- Another advantage is that treatment with the device according to the invention is not associated with pain or other inconveniences. The patient's acceptance is therefore likely to be high.
- Treatment with the device according to the invention can be used in many pathological conditions or functional disorders of the Eye, so that the sum of all functions of the visual organ, namely the visual acuity, the accommodation capacity, the color vision, the dark adaptability and the visual field are favorably influenced. Treatment with the present device can also be extended to diseases of the adnexa.
- binoculars can advantageously be used
- the invention also accelerates wound healing, both postoperatively and post traumatically, as well as an increase in wound firmness in the case of recurrent corneal erosions, epithelial damage in the dry eye, burns, burns etc. let achieve.
- the device according to the invention is advantageously also suitable for the treatment of allergy-related changes in the eyelids and conjunctiva of the eye.
- inflammatory diseases including bacterial and viral genesis, such as, for example, keratitis, ophthalmic zoster, uveitis, central chorioretinitis and neuritis, can be accelerated by the treatment.
- vascular processes such as spasms, stenoses, occlusions, bleeding, edema, etc. treat successfully.
- the device according to the invention can also be used for degenerative eye diseases, for example in retinal or successfully use macular degeneration and vitreous opacification.
- the use of the present invention for treating glaucoma is of essential importance.
- Trans-scleral radiation in the limbus area can lower the intraocular pressure and thus partially reverse a restriction of the visual field and visual acuity.
- the method according to the invention can also be used for diagnosis in the case of normal pressure glaucoma. This condition causes glaucoma damage despite normal intraocular pressure, making it difficult to diagnose early. If the actually normal intraocular pressure drops after radiation, there is suspicion of normal pressure glaucoma.
