Key points for diagnosis
1. Clinical Manifestations
(1) The affected eye, with a foreign body and burning sensation, suffers from photophobia, dacryorrhea and watery secretion; and dim vision occurs in the later
course.
(2) The lid becomes edematous; the palpebral and bulbar conjunctiva are obviously congested with chemosis and; two or three days after the onset of the disease, for lliculi occur in the palpebral conjunctiva and the fornix, sometimes with local bleeding beneath the conjunctiva.
(3) The lymphoglandulae auriculars anteriores of the affected side get swollen and tender to compression.
(4) Eight to ten days after the onset, the inflammation of the conjunctiva gradually relieves, and there arises the spotty infiltration (0.5 to 0.7 mm in diameter caused by adenovirus type 8). The lesion is largely concentrated in the middle of the cornea without ulceration and pannus. The corneal damage may leave the round superficial cloudmess on the cornea, which may disappear in a few months or years.
(5) The incubation period of the disease is about 5 to 12 days with 8 days in most cases. The disease often starts in both eyes successively.

2. Laboratory Examination
Adenovirus can be isolated from the secretion culture of conjunctival sac in some cases.

In TCM, a disease or a symptom might be caused by one pathogenic factor, even two or three pathogenic factors. When diagnosing a disease or a symptom, TCM doctors must follow the principle of "Syndrome Dfferentiation", and then "Suit the Remedy to the Case". In order to gain a more definite and valuable diagnosis, it's important and necessary for the doctor to learn the detailed health information of the patient, including his/her disease duration, age, sex, height, weight, family history, urine, stool, diet, sleep, sweat, energy, mood (emotion), as well as the tongue conditions and the palm conditions, etc. If you would want our expert to create a TCM diagnosis, you're welcome to contact us.
