Quantitative detector for Muscae volitantes

Abstract

The invention discloses a quantitative detector for muscae volitantes. The quantitative detector is a metal square box device forming an all-closed visual space. Milk white PC plastic is arranged on the inner wall of the square box device, and a lower jaw carrier is mounted at the lower end of the square box device and is connected to a table top through a left stand column and a right stand column. A left eye endoscopy lens and a right eye endoscopy lens are mounted on the outer side of the front end of the square box device. A movable shielding piece is mounted on each of the left eye endoscopy lens and the right eye endoscopy lens. Four inner visual space supplement light sources are mounted at four inner corners of the front end of the square box device. A liquid crystal display screen is mounted at the rear end of the square box device and is connected with a computer of a doctor. The liquid crystal display screen and a screen of the computer of the doctor can sequentially display eight muscae volitantes quantitative detection template pages synchronously. The quantitative detector is simple in structure, convenient to operate and capable of detecting muscae volitantes of patients quantitatively; the muscae volitantes of the patients can be discovered by the doctor in an outpatient department timely, and the objectives of early discovery and early treatment are achieved; the doctor in the outpatient department can acquire accurate and clear quantitative cognition of muscae volitantes symptoms of the patients, and make a quantitative detection report for the muscae volitantes.

Description

technical field [0001] The invention relates to an ophthalmological detection instrument, in particular to an instrument for quantitative detection of eye floaters. Background technique [0002] Floaters are a subjective symptom of vitreous degeneration and turbidity in patients with various eye diseases, which can be divided into physiological and pathological. Patients with mild floaters may not necessarily know that they have floaters in the daily visual environment. The current ophthalmoscope and other instruments cannot detect the symptoms of vitreous degeneration and opacity in patients with mild floaters. Only under the specific milky white and sky blue visual background, can the patient feel and find lighter floaters by focusing his eyes on observation. When the patient obviously felt that the floaters had affected his eyesight and went to see a doctor, the eye disease had already reached a serious level. When the patient describes the existence of floaters to the ...

AI Technical Summary

Problems solved by technology

When the patient describes the existence of floaters to the doctor, the doctor cannot accurately quantify and understand the specific symptoms of the patient's actual floaters due to the lack of reference

However, there is currently no instrument for the quantitative detection of eye floaters
