Patient: Description (onset, main symptoms, hospital visited, etc.): IOP was measured in June 2010 at Yangshan County People’s Hospital in both eyes; right eye: 24 mmHg, left eye: 23.7 mmHg. After external eye drops of timolol maleate and internal vinpocetine tablets, IOP was measured several times and fluctuated between 18 and 30 in both eyes until mid-February 2011. On February 22nd of this year, he went to Guangzhou Love Eye. On February 22, 2011, he went to Guangzhou Aier Eye Hospital to have his right eye pressure checked at 19mmHg and his left eye pressure at 20.Both eyes had a visual acuity of 1.2:0. Right C/D=0.66, left C/D=0.59, open angle glaucoma. On March 1, IOP was measured at Yangshan County People’s Hospital: 19.5 in the right eye and 21.7 in the left eye, and on March 2, IOP was 21.0 in the right eye and 21.7 in the left eye. On March 15, the pressure was measured: 22.5 in the right eye and 20 in the left eye. On March 17, the pressure in the right eye was 17 and 20 in the left eye. Later, I went to Guangzhou Aier Eye Hospital for a review, and in view of my long-term use of various medications, my IOP still fluctuated greatly and my visual field and OCT papilla had changed, so trabeculectomy was recommended. Now I heard that your hospital has modern treatment technology for glaucoma, I wonder if this treatment is suitable for my glaucoma treatment, how long does it take to control the disease and how much does the treatment cost? First Hospital Ophthalmology: Hello! The current treatment for open-angle glaucoma in our hospital is vacuum trabeculoplasty. The action of vacuum trabeculoplasty is entirely mechanical, stretching and simultaneously extending the trabecular meshwork by applying precise negative pressure to the eye, thereby reducing the resistance to atrial outflow and improving it for the purpose of lowering intraocular pressure. The advantages of this treatment method are that it is non-invasive, safe and effective. The IOP can be reduced by an average of 6mmHg after treatment. According to your description, you should be suitable for this treatment method. If the IOP is well controlled, you can do without IOP-lowering medication. The effect of the treatment will last about 3 months. First Hospital Ophthalmology: The surgery cost about 2,000 yuan for both eyes at a time (excluding examination fee and bed fee), which is covered by medical insurance reimbursement Patient: Professor: Hello, I am from Yangshan County and I am 57 years old. After reading your reply to me, I have the following questions: 1:Is it necessary to re-treat with vacuum trabeculoplasty after 3 months of glaucoma treatment, and is it necessary to have a long-term cycle of treatment. 2:Is it necessary to make an appointment to facilitate hospitalization. 3:How long does it take to be discharged from hospitalization. First Hospital Ophthalmology: Hello! Vacuum trabeculoplasty for open-angle glaucoma has achieved good results clinically and patients are satisfied. Some treatments can be done without IOP-lowering medications and surgery is avoided. After 7 days of the first treatment, we have to repeat the treatment once, and we have to be hospitalized for a week, and when we need treatment later depends on the IOP situation, and we can be discharged after 2~3 days of hospitalization again. Patient: Professor: Hello. In my case, should I undergo trabeculectomy or vacuum trabeculoplasty? What are the advantages and disadvantages of each of the two treatment methods. Do I need to make an appointment for inpatient treatment at your ophthalmology hospital or do I need to go through any procedures in advance? I am from Yangshan County, Guangdong Province, 170 km from Guangzhou City. Thank you.
