lacrimal examination

The lacrimal examination included slit lamp examination, tear secretion test, tear film rupture time, and fluorescein staining. If the tear film rupture time is normal, the tear film-related diseases can be excluded, and the shortening considers the tear film instability, the tear secretion test is normal, and the meibomian gland dysfunction is considered, and the abnormal one is the tear-deficient dry eye.

Clinical significance Abnormal result If the tear film rupture time is normal, the tear film-related diseases can be excluded, and the shortening considers the tear film instability; the tear secretion test is normal, considering the meibomian gland dysfunction, and the abnormal one is the tear-deficient dry eye. People who need to be examined: excessive secretion of tears or other eye diseases. Precautions Pre-examination contraindications: avoid emotional stimuli, treat eye inflammation, and reduce reflex tear secretion. Requirements for examination: symptomatic treatment and treatment according to different causes, remove the cause and control the secretion of tears. Inspection process Pay attention to the presence or absence of a mass in the lacrimal gland, the size of the punctum, the position and the changes in the skin of the lacrimal sac, and the presence or absence of secretions from the lacrimal sac. The sodium fluorescein or red mercury droplets can be used. After a minute, the cotton sheets pre-set in the nasal cavity and nasal passages are colored to determine whether the lacrimal passage is smooth or the lacrimal passage is used to judge the obstruction. Not suitable for the crowd There is no scope for this, and it is unnecessary to check if the eyes are fine. Adverse reactions and risks May cause eye infections.
