Patient: Name of medication: Ginkgo biloba capsule, Yixingkang capsule, cytophosphatidylcholine na tablets, methylcobalamin capsule Dosing instructions: all three times a day, one tablet at a time July 1, 2013 when eating suddenly can not see in the right eye. Eye examination: visual acuity: right HM/20CM intraocular pressure: right 12.8 MMHG, conjunctiva without congestion and edema, corneal transparency, atrial flash (-), pupil round, right eye 5mm, sensitive to light reflex, crystal mild clouding CINIPI, vitreous mild flocculent clouding. Fundus: the right eye has a pale optic disc with normal color, a small patch of retina can be seen on the temporal side of the optic disc, the arteries are slender, A:V=1:3, the retina in the posterior pole is gray and edematous, and the macula is cherry red. After two weeks of treatment, the disease did not improve. I also have coronary heart disease and rheumatic heart disease, and I would like to ask if there is any possibility of cure. The central retinal artery, once completely blocked, will immediately cause ischemia, hypoxia, cellular degeneration and necrosis in the five layers of the retina in the supply area. A few minutes after blockage, the inner retinal organelles start to degenerate. In monkey eyes, irreversible damage to the retina was observed after 90 minutes of complete retinal artery blockage, and the nuclei began to degenerate and disintegrate after 3 to 4 hours. According to the above, central retinal artery blockage is poorly treated unless recanalization is restored within a very short time. Combined with your condition, it has been treated for two weeks without improvement, and it is difficult to restore vision with further treatment. Oral administration of some drugs to improve microcirculation may have some significance in preventing blockage of blood vessels in the other eye or other parts of the eye, and it is recommended to use them under the guidance of a doctor.
