Description

{Vision examination diagnostic system to measure various eyelid and eyebrow related dimensions before and after eye and eyebrow surgery}

The present invention relates to a vision examination diagnostic system for measuring various eyelid and eyebrow-related dimensions before and after eye and eyebrow surgery, and more particularly, to a vision examination diagnostic system capable of measuring various eyelid and eyebrow-related dimensions before and after eye and eyebrow surgery using an optical system and visualizing the same.

Eyelid surgery is one of the most performed surgical procedures in Korea, and in addition to cosmetic surgery, surgeries for eyelid diseases are also continuously increasing.

Ptosis is a condition in which the upper eyelid droops, making the eye appear smaller.

In other words, ptosis refers to a condition in which the strength of the muscles that raise and lower the eyelids is weakened, causing the upper eyelids to droop and the eyelid crease to become smaller, as shown in Figure 1.

Symptoms that appear when the eyelid droops can cause problems with vision development in children, and can also have a negative emotional impact due to cosmetic problems.

In adults, it is not only a cosmetic problem, but in severe cases, the eyelids can block the field of vision, making daily life uncomfortable, and sometimes even causing headaches because the frontalis muscle lifts the eyelids.

Currently, in clinical practice, when examining ptosis, doctors roughly measure the degree of ptosis on both sides with the naked eye while holding a ruler in front of the eye. However, this is not only inaccurate, but also has the limitation of making it difficult to make consistent measurements because the head position is not fixed, so the head position changes each time it is measured.

Accordingly, there is a need to develop a method that can objectively and accurately measure the condition of the eyelids in real time or a device that can objectively diagnose it.

FIG. 2 is a drawing schematically showing the configuration of a vision examination diagnostic system for measuring various eyelid and eyebrow-related dimensions before and after eye and eyebrow surgery according to the present invention, and FIG. 3 is a drawing schematically showing the configuration of measuring equipment in the vision examination diagnostic system of FIG. 2.

A vision examination diagnostic system for measuring various eyelid and eyebrow-related dimensions before and after eye and eyebrow surgery according to the present invention comprises a main body positioned vertically facing a human face, and a processor electrically connected to the main body and having a program installed therein for measuring various eyelid and eyebrow-related dimensions before and after eye and eyebrow surgery.

The vision inspection system according to the present invention comprises: a measuring device including a plurality of cameras, a plurality of infrared LEDs, a plurality of display LEDs, an LED controller, and a measuring room server; and a client server that receives the measured information from the measuring room server of the measuring device and enables remote consultation.

The present invention uses an LED controller to alternately turn on and off the upper and lower display LEDs, which are arranged vertically among the display LEDs arranged in the main body, and measures eyelid and eyebrow-related dimensions according to the movement of the eyes of a person looking at the displayed LEDs that are turned on.

FIG. 4 is a drawing showing a camera, IR LED, display LED, and main body of a measuring device in a vision inspection diagnosis system according to the present invention, and FIGS. 5 and 6 are photographs showing a measuring device in a vision inspection diagnosis system according to the present invention.

A plurality of cameras are installed horizontally and spaced apart from each other in the middle of the main body of the measuring device of the present invention to photograph the left eye, the right eye, and the entire face, respectively.

The cameras are arranged to capture the left eye, right eye, and entire face respectively, and can consist of two IR cameras and one RGB camera.

The distance between the center of the pupil and the edge of the eyelid (Marginal Reflex Distance: MRD) is measured using the image captured by the IR camera and the ptosis measurement program included in the processor described below.

The RGB camera captures the entire human face, and the processor acquires data for each frame captured by the RGB camera and filters it to measure the Marginal Reflex Distance (MRD) using only the data for cases where the human face is perpendicular to the camera.

It is desirable that the three cameras configured in this manner be arranged parallel to each other on a horizontal line in the middle of the main body.

Infrared LEDs are installed in multiple locations on the main body near multiple cameras to irradiate infrared rays onto the human pupil to detect it.

The display LEDs are provided in multiple numbers and installed on the main body and arranged at regular intervals on the same vertical line of the main body.

The mounting part is installed facing the main body and supports the person's face so that the person's face is perpendicular to the camera.

The support connecting part connects and supports the main body part and the mounting part.

Figure 7 is a drawing showing a state in which a face is fixed to a mounting part of a measuring device in a vision inspection diagnosis system according to the present invention.

The present invention comprises: a measuring device including a mounting portion for mounting a person's face so that the face of the person is perpendicular to the camera and is installed opposite to the main body portion; a measuring room server for storing information measured from a plurality of cameras; and a client server for receiving the measured information from the measuring room server of the measuring device to enable remote consultation.

At this time, the processor may include a program that obtains data for each frame captured by the camera and filters it to measure various eyelid and eyebrow related dimensions before and after eye and eyebrow surgery using only the data when the human face is perpendicular to the camera.

Figure 8 is a drawing showing a state of calibrating a camera using a calibration board, Figure 9 is a drawing showing a calibration board, and Figure 10 is a drawing showing a camera calibration process.

A calibration board in the shape of a chessboard is vertically installed in the stand, and a vision examination diagnostic system for measuring various eyelid and eyebrow-related dimensions before and after eye and eyebrow surgery can be provided by calibrating a camera using the calibration board.

It is important to ensure that the chessboard is held exactly vertical/flat.

Figures 11 to 14 are drawings showing measurement items measured using the vision inspection diagnostic system according to the present invention.

MRD (Marginal Reflex Distance) is the distance from the eyelid to the center of the pupil.

MRD1 is the distance from the center of the pupil to the upper eyelid margin, and indicates the 'degree of ptosis'. (4-5 mm for Westerners, slightly less for Asians)

Drooping eyelids are a condition in which the height of the upper eyelid is lowered due to various causes.

It is defined as a condition in which the margin reflex distance (MRD) between the midcorneal reflection, which is the center of the eye when the eyes are looking straight ahead, and the upper eyelid margin is lower than normal or has a large difference between the two eyes.

The muscles that raise the upper eyelid are the levator palpebrae superioris muscle, the conjunctiva-Müller muscle, and the frontalis muscle.

Any factor that affects the function of these muscles can cause drooping eyelids.

The two most common causes of ptosis are congenital ptosis, which is caused by a congenital deficiency of the levator palpebrae major muscle in infants and toddlers, and involutional ptosis, which occurs as people age and the levator palpebrae major muscle becomes weakened as it is replaced by fat.

Other possible causes include long-term use of contact lenses, history of multiple eye surgeries, Horner syndrome, drooping eyebrows due to facial nerve paralysis, myasthenia gravis, third cranial nerve palsy, progressive external ophthalmoplegia, and traumatic damage.

In some cases, drooping of the eyelid occurs when opening the mouth or moving the jaw to one side due to abnormal synapsis between the trigeminal nerve and the oculomotor nerve in the brainstem.

When the degree of drooping eyelids is mild and does not affect the pupil, symptoms such as a feeling of heaviness when opening the eyes, a sleepy appearance to others, or an asymmetrical eyelid height that does not look cosmetically pleasing often occur.

If the degree is severe and the pupil is invaded, the upper visual field is blocked, making it uncomfortable to see, so the patient may feel better looking by lifting the eyelid or lifting the chin, or may develop the habit of using the forehead muscles to open the eyes, and deep wrinkles may form on the forehead.

If it invades the center of the pupil, it will cause central vision and visual acuity to deteriorate.

In cases of sudden onset ptosis, it may be secondary ptosis caused by another disease rather than congenital or senile ptosis, so taking a medical history about the onset of ptosis is helpful in making a differential diagnosis.

The method of measuring MRD1 is explained as follows.

(1) Set up your face and camera so that both eyes come out of the IR camera.

(2) The MRD1 measurement algorithm is run from the captured image to obtain the pupil and upper eyelid point (x, y) values.

(3) Measure the pixel distance between the detected pupil center and two points on the upper eyelid.

(4) Calculate the actual distance (mm) per pixel from the reference object whose actual length is known.

(5) The actual distance of MRD1 is calculated by multiplying the MRD1 measurement value (pixel) by the actual distance value per pixel.

(6) MRD1 values are measured in three cases: looking straight ahead (center), looking upward, and looking downward.

MRD2 is the distance from the center of the pupil to the lower eyelid margin.

PFH (Palpebral Fissure Vertical Height) refers to the vertical height of the palpebral fissure, and is also called palpebral fissure width.

Other measurement items are specifically organized based on Figures 11 to 14 as follows.

(1) MRD1 (Marginal Reflex Distance): The distance between the center of the pupil and the center of the upper eyelid margin, L_MRD1, R_MRD1

(2) MRD2 (Marginal Reflex Distance): The distance between the center of the pupil and the center of the lower eyelid margin, L_MRD2, R_MRD2

(3) PFH(=MRD1+MRD2): L_PFH, R_PFH

(4) CER (Cornea exposure rate = exposure rate of cornea (black pupil)): L_CER, R_CER

(5) Inter Pupil Distance: IPD

(6) Inter Canthus Distance: ICD

(7) Medial White-area Rate (MWR): The ratio of the exposure of the inner white of the eye to the total eye area (determining the effect of the medial white-area), R_MWR, L_MWR

(8) Lateral White-area Rate (LWR): The ratio of the exposure of the outer white of the eye to the total eye area (determining the posterior and inferior sclera effects), R_LWR, L_LWR

(9) Eyebrow height at 4 points (inner canthus-pupil center-outer canthus-end of eyebrow line): L_EA, L_EC, L_EF, L_EG, R_EA, R_EC, R_EF, R_EG
