Description
Technical field
The invention belongs to medical instruments field, relate to a kind of inferior palpebral margin pressure detector; This detector can be used for lower margo palpebrae pressure measxurement, and has safety, effective, hurtless measure, reproducible, easy advantage, and detecting the data obtained can provide science objective foundation for the diagnosis of various eye surface diseases and pathogenetic research.
Background technology
In clinical ophthalmology disease, due to reasons such as birth defect, cicatrization, periocular muscle dysfunctions, can cause multiple common eyelid disease, occur that lower eyelid tension force increases, margo palpebrae is to the change of eyeball pressure; As entropion, cause margo palpebrae-eyeball surface pressure to increase, there are trichiasis and cause shed tears, the malaise symptoms such as photophobia, foreign body sensation.Have research to point out, the described conjunctivochalasis cause of disease is that lower margo palpebrae tension force increases, and is to cause patient's conjunctiva that relaxes to be piled up in the key factor of margo palpebrae, epiphora etc.; Lower margo palpebrae " introversive type " and " i nternal lined type " conjunctivochalasis patient, slightly push vestige even as seen under eyeball surface slit lamp.As can be seen here, lower margo palpebrae tension detection has very important effect to the diagnosis of multiple common oculopathy, classification.Meanwhile, comprise local application, operative treatment, acupuncture and tuina-massage, treatment by Chinese herbs etc. for lower margo palpebrae treating correlative diseases mode at present, the therapeutic evaluation of different therapeutic modality can only be undertaken by the alleviation of patient's subjective feeling and clinical symptoms.Current, need a kind of objective indicator that easy, effective, that wound is less measuring method can be utilized to obtain margo palpebrae tension force under patient, select therapeutic regimen to help doctor.
At present, there is no the method for generally acknowledging and measuring lower margo palpebrae tension force in the world.There is foreign scholar once to develop a kind of lower margo palpebrae tension tester, by grip patient's margo palpebrae eyelashes, be pulled outwardly and measure corresponding pulling force after shutting down margo palpebrae certain distance and indirectly determine lower margo palpebrae tension force; But this gauge complex structure, poor accuracy, and patient need bear wound risk, therefore cannot be widely used in clinical.
Therefore, current in the urgent need to a kind of inferior palpebral margin pressure detector; This detector can be used for lower margo palpebrae pressure measxurement, and detecting the data obtained can provide science objective foundation for the diagnosis of various eye surface diseases and pathogenetic research.
