She came to our hospital because she had a sense of blocked vision in her left eye. Through ophthalmologic examination combined with cranial CT examination and fundus angiography of both eyes, it was clear that she suffered from optic neuropathy, and she was treated with potassium chloride slow-release tablets, prednisone acetate tablets, and methylcobalamin tablets, and the symptoms improved in 6 days without any other discomforts. Basic information] Female, 59 years old [Type of disease] Optic neuropathy (ischemic optic neuropathy of the left eye) [Hospital] The First Affiliated Hospital of Xi’an Jiaotong University [Date of consultation] January 2022 [Treatment plan] Drug treatment (potassium chloride extended-release tablets, prednisone acetate tablets, methylcobalamin tablets) [Treatment cycle] Hospitalization for 6 days, 1 month later for a follow-up examination [Effect of treatment] The sense of occlusion of the left eye disappeared. I. Initial Consultation The patient, Auntie Wang, is 59 years old. She reported that a month ago, she suddenly developed a sense of blocked vision in her left eye, and sometimes there were dark shadows in front of her eyes, but there were no other symptoms such as pain or foreign body sensation. Through ophthalmologic examination, visual acuity: right eye 4.9, corrected 5.0, left eye 4.7, corrected 5.0; intraocular pressure: right eye 18mmHg, left eye 16mmHg, both tear ducts are flushed smoothly; pupil of the right eye is round, about 3mm in diameter, with normal light reflex, while the pupil of the left eye is round, about 4mm in diameter, with dull light reflex; fundus: the edge of the right eye’s optic disk is clear, color is normal, arterioles are fine, veins are tortuous, and there are scattered spots and flakes in the macular area. The fundus of the right eye was clear with normal color, fine arteries and tortuous veins, scattered punctate exudation in the macular area, and unclear reflection in the center; the fundus of the left eye was clear with blurred optic disc margins, scattered hemorrhages around the periphery, pale color, optic papillary edema, fine arteries and tortuous veins, and unclear reflection in the center. The preliminary diagnosis was optic neuropathy (ischemic optic neuropathy of the left eye). The patient underwent cranial CT and fundus angiography in both eyes, and was found to have no abnormalities on cranial CT and ischemic optic neuropathy on fundus angiography in both eyes. Since the symptoms of occlusion in the left eye were affecting the patient’s daily life, I suggested that he be admitted to the hospital for treatment of this disease and be discharged home to recuperate after his condition improved. The patient agreed and was given a medication regimen to reduce edema, improve circulation, and nourish the retina of the optic nerve. Prednisone acetate tablets were used to reduce edema and dilate blood vessels, and methylcobalamin tablets were used to nourish the optic nerve. Potassium chloride extended-release tablets were also required for prophylactic potassium supplementation. After 6 days of hospitalization, the patient’s condition improved and he was discharged home for recuperation. However, the patient needed to follow the doctor’s instructions to adhere to the medication and go to the hospital for review after 1 month. After 6 days of medication in the hospital, the patient realized that the symptoms of occlusion of vision in the left eye had been reduced, and the symptom of black shadow in front of the eyes had disappeared. The ophthalmologic examination showed that the edge of the optic disc in the left eye was clearer than before, the peripheral hemorrhage was absorbed compared with before, and the edema of the optic papilla was reduced, which indicated that the medication was effective and the patient could be discharged from the hospital to go home for recuperation. 1 month later, he came to the hospital for a recheck and found that the sense of occlusion of the vision of the left eye had completely disappeared, and there was no recurrence of his condition, which indicated that his condition had been cured, and he was advised to pay attention to the follow-up consultation in the event that the patient had any discomfort symptoms. I am very happy that the patient’s condition has gradually recovered and she can be discharged from the hospital and go home to recuperate. However, I still need to tell Auntie Wang to pay attention to the protection of her eyes during the period of home recuperation, avoid rubbing her eyes with her hands when she is not feeling well, and rest more in general, ensure enough sleep and avoid staying up late. In daily life or at work, avoid excessive use of eyes, reduce the use of computers, television, cell phones and other electronic devices, so as not to aggravate the discomfort, affecting the recovery of the eyes. In terms of diet, it is necessary to pay attention to more vitamin-rich foods, such as carrots, spinach, oranges, bananas, etc., which are helpful for eye recovery. V. Personal perception Optic neuropathy can be caused by a variety of reasons, including optic nerve infection or optic nerve ischemia. In this case, 59-year-old Auntie Wang had optic neuropathy due to optic nerve ischemia. The symptoms are relatively mild and can be cured with medication. However, there are some patients with severe ischemic optic neuropathy who have already suffered a significant loss of vision and sometimes even blindness when they seek medical attention, which is usually incurable and has more serious consequences. Therefore, we still hope that you pay attention to protect your own eyes, and promptly consult a doctor when symptoms occur.
