Problems solved by technology

However, such a gazing space position is blurred, and it is difficult for the gaze of the observed object to reach the ideal expected position. The operator needs to remind the patient to change the gazing space, the detection efficiency is low, and it is difficult to guarantee the detection accuracy.

Abstract

The invention relates to the technical field of ophthalmology detection equipment, in particular to a staring device and a handheld ophthalmoscope. The staring device comprises a central point, a middle point light source arranged on the central point and at least one telescopic rod. One end of the telescopic rod is connected with the central point, the other end of the telescopic rod is provided with an outer end point light source. The handheld ophthalmoscope comprises an ophthalmoscope and further comprises a staring device. The staring device is arranged on the left or right of the ophthalmoscope. The staring device can adjust the staring angle of a patient according to actual detection condition requirements and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of ophthalmology detection equipment, in particular to a gaze device and a hand-held ophthalmoscope. Background technique [0002] In terms of biomedical applications, understanding the condition of the fundus of the eyeball can help to judge the occurrence and development of various diseases such as fundus diseases, high blood pressure, and diabetes. There are many kinds of fundus observation devices, which are usually divided into fixed desktop and handheld. In order to observe the bottom of the eyeball, the light needs to pass through the pupil (referred to as "into the pupil", the same below). During the operation of the handheld ophthalmoscope, the observer, It is necessary to tell the observed object to fixate or change to fixate on a certain spatial position of gaze, and manually adjust the observation angle, observation position, brightness or curvature of the hand-held ophthalmoscope to make the fie...
