Technical Field

The invention relates to the technical field of eye sight, in particular to a head-mounted device for shooting images of people in different positions.

Background

The selection of the operation center in the corneal refractive surgery has important influence on the imaging quality of human eyes after the surgery. Measurements prior to refractive surgery were all done in the sitting position, while surgery was done in the lying position. Researches show that the pupil center position and the size of human eyes can be changed to a certain extent in different body positions, so that certain uncertainty is brought to the operation effect, and the postoperative human eye imaging quality is influenced. Therefore, it is necessary to measure the center of the pupil of the eye, the diameter of the pupil and the change of the reflection point of the cornea in different positions.

Existing ophthalmic devices, such as corneal topographers, can measure pupil information of a person's eye in a seated position, but cannot measure data of a person's eye lying down. In the technology of iris positioning and tracking and the like in the equipment in the operation, the pupil information of the human eye in the lying position is measured, and the pupil information in the sitting position cannot be measured. If different devices are adopted to respectively measure the pupil information of the eyes in the sitting position and the lying position, the uniformity of eye images in different body positions cannot be ensured due to different sighting marks when different instruments shoot, and some uncertain factors exist if the measurement results of the two devices are directly compared. In addition, these devices are large medical instruments that are fully functional, but are expensive and not easily portable.

The research provides a measuring device which is low in price, simple in structure, light in weight and convenient to hand and move. More importantly, the device can measure the information of the pupils of the human eyes and the reflective points of the cornea in the sitting position and the lying position, and solves the defects of the clinical equipment.

The using method comprises the following steps:

before the user wears the illuminating lamp 2, the power supply of the illuminating lamp 2 is turned on, so that the illuminating lamp 2 keeps a stable luminous normally-on state. The camera of the mobile phone faces the direction of a patient, then the clamp 15 is lifted to slide upwards, then the mobile phone is placed between the clamp 15 and the supporting plate of the bracket 14, then the lifting force applied to the clamp 15 is stopped, and the clamp 15 slowly slides downwards until the mobile phone is clamped; covering the eye mask on the face of the patient, the eyes of the patient being aligned with the first and second holes 9 and 10, respectively; the fixing device is then placed on the head of the patient, and the present invention is fixed to the head of the patient by adjusting the first fixing band 1 and the second fixing band 8 so that the fixing bands are adapted to the head sizes of different patients, so as to keep the position of the human body unchanged during photographing.

The invention is simple and portable, has multiple dimensions and is adjustable, and is suitable for different people to use and simultaneously improves the use comfort of users.

Specific examples of use

Using specialized medical instruments, the pupil center position of 30 eyes was marked and the corneoscleral margin was defined as the origin of coordinates with the X-axis being laterally offset and the Y-axis being longitudinally offset. Then, the pupil center positions of the 30 eyes in the sitting position are marked by using the invention, and the positioning positions of the pupil center positions are compared with the defined coordinate origin, so that the sitting pupil center position distribution diagram shown in the figure 5 can be obtained, and it can be seen that the positions of the pupil centers in the sitting position are concentrated on the X axis: 0.15 ± 0.11mm, Y-axis: 0.08 ± 0.0.16mm, wherein when X >0, the observation point is on the side close to the nose, and when X <0, the observation point is on the side far from the nose. When Y >0, the observation point is on the side close to the forehead, and when Y <0, the observation point is on the side far from the forehead.

Under the condition that other conditions are not changed, the body position of the patient is changed from a sitting position to a supine position, then the center of the corneosclera margin is still used as a coordinate center, the X axis is at a transverse offset position, and the Y axis is at a longitudinal offset position; by waiting for the distribution of pupil center positions in the supine position as shown in fig. 6, it can be seen that the pupil center positions in the sitting position are centered on the X-axis: 0.46 ± 0.21mm, Y-axis: 0.37 + -0.14 mm, wherein when X >0, the observation point is on the side near the nose, and when X <0, the observation point is on the side far from the nose. When Y >0, the observation point is on the side close to the forehead, and when Y <0, the observation point is on the side far from the forehead.

Results of use

By experiment we found that on the X-axis: pupil of 30 eyes 27 the pupil centers of all the eyes are displaced toward the nose, and 3 eyes are not significantly displaced toward the nose or in the opposite direction, on the Y axis: 24 eyes were displaced toward the forehead, 3 eyes were displaced in the opposite direction, and 3 eyes were not significantly displaced. It is not difficult to infer from the data that the pupil positions of most people move toward the nose side while approaching toward the forehead side, and the movement amplitude in the X axis is larger than that in the Y axis.

The measurement process at the pupillary reflex point found when the limbal center was taken as the origin of coordinates. The positions of the reflecting points of each patient are different greatly, the kolmogorov-smirnov test shows that P is larger than 0.05, the experimental data do not have normal distribution characteristics, but when the body position of a testee changes, the position change condition of the reflecting points has normal distribution characteristics, so that I mainly analyze the displacement condition of the reflecting points. Wherein the displacement on the X-axis: 0.19 ± 0.13mm, see in particular fig. 7, displacement on the Y axis: 0.64 + -0.34 mm as shown in FIG. 8.

It can be seen that when the corneal reflection points are changed from the sitting position to the supine position in the human body position, 25 of 30 reflection points move towards the nasal side, 5 reflection points move towards the outer side of the nose and move towards the forehead in the Y-axis direction, and obviously, the movement amplitude of the corneal reflection points in the Y-axis is larger than that of the corneal reflection points in the X-axis direction.

Therefore, it can be seen that the position of the corneal reflection point has large deviation under different postures, and multiple measurements are needed. The head-wearing device for shooting the images of the human eyes in different positions, disclosed by the invention, is simple in structure, can finish the measurement of the positions of the reflecting points of the through holes in different positions without using a head fixer consisting of a forehead belt and a mandible support which are difficult to move in ophthalmologic measurement, obtains the images of the human eyes in different positions, is convenient for a doctor to quickly position an operation point, and improves the efficiency of the operation.

In further upgrading simultaneously, can be integrated to shooting cell-phone 6 with professional processing software or application APP, can directly handle the image of shooing, the required pupil center data and the cornea reflection of light point data of people's eye of direct output, and need not to handle after exporting the computer with the image of shooting cell-phone 6 shooting again, it is more convenient to use, applicable more occasions of not being convenient for carry the computer, improves application scope.
