Key points for diagnosis
1. Clinical Symptom
The patient's vision diminishes abruptly.

2. Fundus Examination
(1) The retinal veins are coarsely large, tortuous, ectatic, obstructed and dark red, and the retinal artery becomes thin and thready.
(2) The retina is of hemorrhage, edema and exudation, and the massive hemorrhage is radiant, flaminglike, patchy and circle-pointed and spreads with the opatic disc as the center.
(3) The optic papilla is congested with edema and the surface is covered with hemorrhage.

3. Fluorescein fundus angiography
At the beginning, the fluorescein reflux of the retinal vein is slow, the filling time deferred, and the obstructed part is displayed in the branched veins. Later on, fluorescein effusion is clearly seen in the capillary with thevenous wall stained and the retina full of strong fluorescent light or covered with macular cystoid edema.

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.
