The blister-like appearance after pterygium surgery may be caused by lymphatic vessel obstruction, postoperative edema, recurrence of pterygium and other reasons.
1. Lymphatic vessel obstruction: If the conjunctival lymphatic vessel is obstructed after surgery, it may cause localized blister-like elevation. If there is no ocular discomfort, it can be observed first, and if the symptoms are obvious, it can be treated with puncture therapy.
2. Postoperative edema: During the postoperative recovery period, there may be edema at the surgical site, which may look like a blister. Generally, it is enough to follow the doctor’s instructions for medication and follow-up.
3. Pterygium: This is a common ocular surface disease. Since pterygium has a high recurrence rate, patients who look like they have a blister after pterygium surgery need to consider that it is caused by the recurrence of pterygium. At the same time, there will be persistent bulbar conjunctival congestion, hypertrophy, mild dry eyes, eye redness, and foreign body sensation.
Therefore, after pterygium surgery, patients need to strengthen the postoperative care, develop good habits, pay attention to eye time and hygiene, and need to go to the hospital for review one week after the surgery, so that the doctor can understand the treatment effect of the surgery.
