Description

Light source device for transmissive micrography and method for observing my boom using the same {Light source device for transmissive meibography and inspection method of meibomian gland using it}

Various embodiments of the present invention relate to a light source device for transmission micrography and a method of observing a myboom using the same.

The corneal anterior larynx (anterior tear film) covering the surface of the eye in the human eye consists of three main layers: the mucus layer, the water layer and the lipid layer. Each layer serves to protect and lubricate the eyes, thus affecting dryness or lack thereof. Drying of the eye is an eye disease commonly known as "dry eye syndrome", "dry eye syndrome", or "dry keratoconjunctivitis". Dry eye can cause symptoms that may cause discomfort, such as pruritus, burning and irritation. There is a known correlation between the thickness of the anterior right film and dry eye disease.

As shown in FIG. 1, the corneal front right membrane comprises the innermost layer of the right membrane that contacts the cornea 10 of the eye 11, known as the mucus layer 12. The slime layer 12 is composed of many slime. Mucus serves to keep the middle layer of the right membrane known as the aqueous layer aqueous. Thus, the mucous layer 12 keeps the cornea 10 aqueous, providing a protective layer and a lubrication function, thereby preventing drying of the eye 11.

The intermediate layer or moisture layer 14 comprises most of the right membrane. The moisture layer 14 is formed by the secretion of the sap by the peripheral lacrimal glands 16 and the para-glandular glands 17 of the eye 11 illustrated in FIG. 2A. FIG. 2B illustrates the eye 11 of FIG. 2A when blinking. The sap secreted by the lacrimal gland 16 and the lye tear gland 17 is generally referred to as "tear." The role of the moisture layer 14 is to wash away the dust, particles, or foreign matter that may enter the eye (11). Another important function of the moisture layer 14 is to provide a protective layer and lubrication to the eye 11 to keep it moist and comfortable. Defects that cause a lack of sufficient sap in the aqueous layer 14, also known as "sap deficiency", are a common cause of dry eye. Wearing contact lenses can also cause dry eye. Since the contact lens may disturb the natural milk film and may decrease corneal sensitivity over time, the generation of tears may occur.

The outermost layer of the right membrane illustrated in FIG. 1, known as the "lipid layer" 18, also serves to prevent drying of the eye. The lipid layer 18 is composed of many lipids known as "myboom" or "sebum" produced by the Maibom lines in the upper and lower eyelids 22, 24 shown in FIG. This outermost lipid layer is very thin and typically has a thickness of less than approximately 250 nm. The lipid layer 18 serves to reduce the rate at which the water layer 14 evaporates by providing a protective coating layer covering the water layer 14. When flashing, the upper eyelid 22 forms a protective coating that covers the eye 11 that constitutes the right membrane with the sap and lipids. If the evaporation rate of the moisture layer 14 is increased, it may cause drying of the eyes. Thus, if the lipid layer 18 is not sufficient to lower the evaporation rate of the water layer 14, there is a fear that the eye may dry out.

Therefore, since the mybom line 20 is involved in secretion of lipids that reduce the evaporation rate of the water layer 14, the mibom line is evaluated as part of the diagnosis of dry eye syndrome.

4A, 4B, and 4C are diagrams illustrating a light source device 100 for transmissive micrography according to various embodiments of the present disclosure.

As shown in FIGS. 4A, 4B, and 4C, the light source device 100 for transmission micrography according to the embodiment of the present invention may include a power supply unit 110, a handle 115, a light emitting unit 120, and light. The conversion unit 130 may be included. In some cases, the light conversion unit 130 may not be provided.

The power supply unit 110 supplies power to the light emitting unit 120. The power supply 110 may be, for example, but not limited to, a power adapter that converts AC power of 110V to 220V into DC power of 1V to 20V. In addition, the power supply 110 may include a primary battery such as a mercury battery and a secondary battery such as a lithium ion / polymer battery.

In addition, the power supply 110 may be provided, for example, but not limited to, inside the handle 115 which can be held by a single hand. Although not shown, the power supply 110 or the handle 115 may be provided. One side of the power supply 110 may include a switch to turn on / off.

The handle 115 may be formed of, for example, but not limited to a plastic material, which may include a power supply 110 in some cases, as described above. The handle 115 has a size that can be easily held with one hand, for example, but not limited to, the shape of the plane may be a rectangular plate, a square plate or an elliptic plate.

The light emitter 120 is electrically connected to the power supply 110 to serve to emit light (transmit or emit light) in a predetermined direction. The light emitter 120 includes, for example, but is not limited to, white light (ie, white light in which all wavelengths are mixed) or a plurality of point light sources 122 emitting light having a single wavelength of approximately 500 nm to 1,300 nm. can do. In other words, the light emitting unit 120 may include a plurality of point light sources 122 (for example, white light emitting diodes) emitting white light including infrared light, visible light (particularly red), and / or all wavelengths. Or may include multiple point light sources 122 (eg, single wavelength light emitting diodes) emitting a single wavelength of approximately 500 nm to 1,300 nm.

Here, as an example, when employing the light emitting unit 120 that emits red light, the myboom line can be directly photographed without an infrared camera. Here, the above-described predetermined direction means a direction substantially perpendicular to the longitudinal direction of the light emitting unit 120. That is, the light emission direction by the point light source 122 of the light emitting unit 120 is a direction substantially perpendicular to the longitudinal direction.

In particular, the light emitting unit 120 includes a circuit board 121 having a substantially rectangular plate shape, a plurality of point light sources 122 arranged in a line or multiple rows on the circuit board 121, and a bottom surface of the circuit board 121. It may include a support plate 123 for supporting. Here, the circuit board 121 may be flexible or rigid, and the plurality of point light sources 122 may be electrically connected to the circuit pattern while being arranged in at least one or multiple rows along the longitudinal direction of the circuit board 121. have.

In addition, one region of the support plate 123 may be attached to the handle 115, and the other region may be attached to the light emitting unit 120. The support plate 123 is not limited, for example, but is formed of plastic or metal having a higher strength and hardness than the light emitting part 120, so that the flexible light emitting part 120 is observed when the boom is observed. It supports to prevent bending. That is, the support plate 123 serves to provide the appropriate force without bending the light emitting part 120 / light conversion part 130 when the lower eyelid is pressed or the upper eyelid is flipped over.

The light conversion unit 130 is mechanically coupled to the upper surface of the light emitting unit 120 and has an area similar to that of the light emitting unit 120. The light conversion unit 130 is in close contact with the upper and lower eyelids and / or the lower eyelids so that the eyelids and / or the lower eyelids can be observed, thereby converting the point light source from the light emitting unit 120 into the surface light source form. It serves to diverge or irradiate the upper or lower eyelids.

Here, the light conversion unit 130 may be formed of, for example, but not limited to, a side glowing optical fiber, a translucent plastic, or a transparent plastic. Further, the light conversion unit 130 may be, for example, but not limited to polyethylene terephthalate (PET), poly (methyl methacrylate) (PMMA), polyimide (PI), polypropylene (PP), polyethylene (PE), or the like. It may be formed.

For example, the light conversion unit 130 may include, but is not limited to, a flat first surface 131, a flat second surface 132 opposite to the first surface 131, and a first surface 131. A third surface 133 that connects one end of the second surface 132 to a smaller surface than the first surface 131 or the second surface 132, and the first surface 131 and the second surface 132. It may include a fourth surface 134 connecting the other end of the first surface 131 or smaller than the area of the second surface 132. That is, the light conversion unit 130 may be in the form of a thin plate, plate and / or stick. In addition, the light emitting unit 120 may be coupled to the first surface 131 of the light conversion unit 130, and the second surface 132 may directly contact the upper eyelid and / or the lower eyelid.

The thickness of the light conversion unit 130, that is, the thickness between the first surface 131 and the second surface 132 may be relatively thin compared to the thickness of the light emitting unit 120 described above. However, since the light emitter 120 is coupled to the first surface 131 of the light converter 130 to provide a point light source, the light converter 130 converts the light into a relatively wide surface light source, that is, a point light source. It scatters / diffuses into a surface light source and serves to irradiate the upper and lower eyelids.

For example, the light conversion portion 130 is in the form of a stick having a width of about 7-8 mm, a thickness of about 2-3 mm and a length of about 35-45 mm, which is in direct contact with the lower or upper eyelids. As a result, the observation or photographing of the inner boom line is easy. That is, the light conversion unit 130 converts the point light source of the light emitting unit 120 into a surface light source having a large area, and diffuses and diverges, thereby easily connecting the inner boom line through the upper and / or lower eyelids. To be photographed and / or observed.

Here, as described above, the light conversion unit 130 is made of side-emitting light fiber, or translucent or so that the point light source of the light emitting unit 120 located below can be converted / transmitted well into the surface light source. It may be formed by injection molding of transparent PMMA, PET, PI, PP, PE and the like.

In this manner, the light source device 100 for transmissive micrography according to the embodiment of the present invention is inverted by the upper and / or lower eyelids so as to easily check the connection of the myboom line formed in each of the infrared and / or Alternatively, it may be provided in the form of a plate or stick that irradiates red visible light.

In particular, the light source device 100 for transmissive micrography according to the embodiment of the present invention has a relatively thin thickness of the light emitting unit 120 and the light converting unit 130, so that not only the upper eyelid but also the upper eyelid My boom line should be easily observed or photographed. That is, in the case of the upper eyelid, the eyelid should be flipped relatively more than the lower eyelid in order to observe or photograph the boom line, and if the thickness of the light emitting unit 120 / light conversion unit 130 is thick, it is difficult to invert the upper eyelid. However, as in the embodiment of the present invention, the thin light emitting part 120 / light converting part 130 in the form of a plate, plate, or stick facilitates inversion of the upper eyelid, so that the inner boom line can be observed or photographed. It becomes easy.

Here, when the light emitter 120 emits infrared rays, the boom line may be photographed using an infrared camera, or the boom line may be photographed with an infrared camera mounted on a microscope for slit lamp for ophthalmic care. In addition, when the light emitter 120 emits red light, an infrared camera is not required, and the doctor can directly observe the eye in a microscope for slit lamp for general ophthalmic care. Of course, it can be taken directly with a visible light camera, or may be taken with a visible light camera mounted on a microscope for slit lamp for ophthalmic care.

5A and 5B are diagrams illustrating a lower eyelid inspection state using a light source device 100 for transmissive micrography according to various embodiments of the present disclosure, and FIG. 5C is a photograph showing a lower eyelid inspection result.

After the 130 is pressed in close contact with the lower eyelid, the light emitting unit 120 is turned on. Then, the light from the wide surface of the light conversion unit 130 (for example, the first surface 131) is incident and scattered on the lower eyelid, and then passes through the myboom line to exit the inner surface. At this time, since the myboom lines reflect infrared or red light, the myboom lines are typically observed in a black (or white) structure.

That is, as shown in Figure 5c, the my boom line is observed to be approximately white through the inner surface of the lower eyelid, so that the doctor can determine whether the my boom line is missing. In other words, the doctor observes the deficiency of the my boom line, the shape of the my boom line, the relative distance between the boom line, the density of the my boom line, and the like to determine whether the my boom line is abnormal in reducing the geological layer.

As shown in FIGS. 6A and 6B, the light source device 100 for transmissive micrography according to the exemplary embodiment of the present invention has a light emitting part 120 / light conversion part in a state where the upper eyelid is pulled upward and inverted. After the 130 is pressed in close contact with the upper eyelid, the light emitting unit 120 is turned on. Then, the light from the wide surface of the light conversion unit 130 (for example, the first surface 131) is incident and scattered on the upper eyelid, and then passes through the myboom and exits to the inner surface. At this time, since the myboom lines reflect infrared or red light, the myboom lines are typically observed in a black (or white) structure.

That is, as shown in Figure 6c, the my boom line is observed to be approximately white through the inner surface of the upper eyelid, so that the doctor can check whether the my boom line is missing. In other words, the doctor observes the deficiency of the my boom line, the shape of the my boom line, the relative distance between the boom line, the density of the my boom line, and the like to determine whether the my boom line is abnormal in reducing the geological layer.

For example, but not limited to, the diffusion sheet 231 converts a plurality of point light sources provided from the light emitter 120 into a surface light source, which is mainly manufactured through an extrusion process and scatters light. Since brightness uniformity must be maintained through the light scattering agent 232 in a matrix such as PMMA or polycarbonate can be prepared by dispersing. In addition, the prism sheet 233 is, for example, but not limited to, after coating a high refractive resin crude liquid (high refractive resin, photoinitiator, ultraviolet curing agent, etc.) on the optical PET film and passing through a roll of the prism shape is imprinted; At the same time, it can be formed by irradiating ultraviolet light so that the prism shape inscribed in the roll is transferred and fixed to the crude liquid on the PET film.
