"I have heard about this from other people, and after returning home I roughly flipped through the medical textbooks my wife had left at home." Mr. Liu is also a high-level intellectual, and he could understand part of what the doctor said.
Seeing that the family members were able to communicate, Cao Yong explained the more in-depth knowledge: "The most important feature of the retinal arterial network is that its blood vessels are very thin. At present, no catheter can enter this place. If an embolus appears in this place, it will be very troublesome. Doctors have limited strategies to deal with this."
"Yes, but I seem to have heard someone say that blocked blood vessels can be treated by dissolving the blood clots and removing the blood clots." Mr. Liu asked around and told his wife all the information he had found for her, not wanting to give up any chance to save his wife.
Thrombectomy and thrombolysis, Mr. Liu's words should refer to ophthalmic artery interventional surgery. I have previously mentioned that the pathogenesis of this disease is similar to myocardial infarction, and similar interventional methods can be used to treat it, such as drug thrombolysis and interventional surgery. However, I have mentioned that ophthalmology cannot perform such interventional surgery. Why is this?
"Whether it's thrombolysis or catheter-based interventional embolectomy, everything has to be done in a timely manner." Cao Yong did not completely deny the news that the family had inquired about, but he was realistic. The family was an outsider and the information they had heard was certainly not professional enough, so some of the information was probably wrong. "Generally speaking, the best treatment is given within a few hours of onset. Your wife, Dr. Hu, is a doctor himself, and he knew that this was an emergency, so he immediately went to an ophthalmologist and took emergency measures. It was also because your wife's self-rescue was very timely that the result of sudden blindness did not occur, and now the embolus is left and cannot move. I saw that the medical records written by the ophthalmology department were roughly like this. In the previous treatment steps of the ophthalmology department, they did not perform angiography on her, and would not consider performing interventional thrombectomy and thrombolysis surgery on the patient at that time."
"Why didn't the ophthalmologist perform surgery on my wife?" Dr. Liu kept asking, suspecting that the ophthalmologist was negligent and not aggressive enough in his treatment.
The ophthalmologist knows that the patients he treats are his colleagues, so how dare he be careless? He cannot cheat his colleagues.
Cao Yong smiled at this point. He was not defending his colleagues but needed to make it clear to the family members: "The effect of thrombolytic therapy via the ophthalmic artery is far less effective than that of interventional surgery for myocardial infarction. The retinal artery is the terminal blood vessel, as I just said. Its diameter is too thin, and there is no such equipment that can break through the physical limit and enter this place. Doctors cannot send the catheter to the precise location for thrombectomy, thrombolysis and stenting like cardiovascular interventional surgery. The effectiveness of the operation is questionable."
Specifically, cardiovascular interventional surgery can deliver catheters and stents to the main coronary arteries that supply myocardial cells, and treat the disease as accurately as a cannonball hitting the diseased area. The surgical effects of thrombus removal and thrombolysis can naturally be immediate. The central retinal artery is too thin to do this, so its interventional surgery cannot be considered a true interventional surgery.

Therefore, it can be seen that there are not many such interventional surgeries in ophthalmology. However, it cannot be said that there are none at all. It depends on whether the patient's condition meets the indications for surgery. Doctors choose to perform ophthalmic artery interventional surgery on some patients, mainly based on the consideration that the embolus may not be in the retinal artery but in the internal carotid artery or the proximal end of the ophthalmic artery.
