Patient: Female, 48 years old, with diabetes mellitus for many years. On January 22nd at 3:00 pm, she suddenly felt unable to see anything in her right eye, and felt a white mist in front of her eyes, and could only see something in one corner of her right eye below the nose. The next morning, the doctor said there was edema and the color of the fundus had changed, and diagnosed the right eye as central retinal artery blockage. He was hospitalized on the morning of the 23rd and received treatment around ten o’clock. He was given medication, compound camptothecin postbulbar injection, glycerol fructose, cerebroprotein hydrolysate, and VC. He was given some oral medication as an adjunct to the treatment. After 9 days of treatment, there was a significant improvement, but I still could not see anything above my right eye, only the upper corner of the eye was a little light sensitive. The first few days of improvement were quite obvious, but the improvement became slower and slower in the later stages. 1. Is there any precedent of curing this disease in China? 2.Can you give me some treatment suggestions for the current symptoms? 3.The doctor said that the injection of camptothecin can only be used for 14 days, but it is not well yet, will it affect the treatment if the medicine is stopped? If this drug is stopped, can I use other drugs for treatment? Li Aijun, Ophthalmology Department, Peking University Third Hospital: 1. The reaction after retinal photocoagulation is normal, and there are no drugs that can be used. 2, divided into four times mainly depends on the patient’s tolerance and the area of the retinal photocoagulation done by the doctor, so you have to follow the requirements of the doctor who did the photocoagulation for you, which is basic. If you review it later and the imaging reveals any problems, it is not likely that you will need additional photocoagulation, which is not considered the fifth time, but only as needed for the eye condition. Patient: I had a fundus fluorescence angiogram, and I already have stage 4 glucose reticulopathy, and I have to have four laser procedures. I’ve already had three laser surgeries, and I didn’t notice much change in my vision the first two times. However, after the third time, I found that my vision had decreased significantly, and my eyes were always foggy and white, and I always felt that there was something in front of me, so I couldn’t see clearly. The doctor said that we still have to finish the fourth laser. We are now worried that after the fourth laser treatment, the vision will not be as good as it is now, so much so that it will affect the work. The patient is in a very bad state of mind, please help us! Do we still need to do the fourth time now? Is it necessary to do it for the fourth time? Will it cause blindness or will it cause the vision to be worse than it is now? We are very anxious, thank you very much! The Third Hospital of Peking University Ophthalmology Li Aijun: 1, diabetic retinopathy to do the whole retinal photocoagulation, is what you think of laser surgery, in fact, is not surgery, sometimes the patient will be painful, unbearable, generally divided into four times, sometimes may have to supplement photocoagulation. 2, photocoagulation during the period will have blurred vision, vision loss and other discomfort, are normal, after a period of time will slowly recover, do not worry too much, really do not feel comfortable to ask the doctor to look at your eye fundus. 3, the completion of photocoagulation is only to prevent further aggravation of glucose reticulopathy, and can not improve vision. Patient: We had the doctor look at it, and he said it was a little edema, and that it would be better once the edema was gone, and that the general recovery period was 7-10 days, and now it’s the fifth day, and I feel that there is still no change. What kind of medicine is more effective in treating edema? And do we have to do it for the fourth time? If we don’t do it, it will affect the effect of the treatment, right? Li Aijun, Ophthalmology Department, Peking University Third Hospital: 1. Central retinal artery blockage is not uncommon and is an ophthalmic emergency. 2, you can use a little poppy base.
