Pterygium excision will have a variety of complications, among which scleral dissolution is the most typical, and patients are naturally more concerned about the reasons. Let's take a look at the scleral dissolution after pterygium excision.

Pterygium excision after scleral dissolution is how to return a responsibility

First, scleral dissolution is related to excessive cauterization during hemostasis. The surface sclera is rich in vascular tissue, while the scleral stroma layer is mainly composed of dense collagen fibers, almost without vascular tissue.

Secondly, excessive cauterization and hemostasis during the operation, on the one hand, directly causes a large number of scleral tissue coagulation and necrosis; on the other hand, it causes the vascular occlusion on the surface of sclera, which seriously affects the process of scleral repair, and causes scleral dissolution and thinning in a short time after operation. If it cannot be treated in time, scleral perforation will appear.

Finally: in the process of pterygium surgery, we should pay attention to the fine operation, must not blindly pursue the "clean and tidy" operation field and excessive cauterization hemostasis, so as to avoid causing scleral tissue dissolution.

matters needing attention

Postoperative dressing should be changed daily, and antibiotics and glucocorticoid eye drops should be used at the same time, which can reduce the recurrence. Postoperative infectious keratitis, which is the most serious complication, should be found in time and treated actively.
