Analysis on reasons and treatment approaches for shallow anterior chamber after glaucoma surgery.

Objective: To analyze the causes of shallow anterior chamber after glaucoma surgery, and explore effective treatments correspondingly.

Methods: A total of 183 glaucoma patients (218 eyes) underwent trabeculectomy, and shallow anterior chambers were observed after surgery. The causes were analyzed and appropriate approaches were employed accordingly.

Results: Postoperatively, shallow anterior chamber occurred in 42 eyes (19.3%) .Among those, 24 eyes (57.1%) had excessive filtrations, 8 eyes (19.0%) showed delayed anterior chamber formation, 5 eyes (11.9%) presented with choroidal detachments, 4 eyes (9.5%) displayed conjunctival flap leakages, and 1 eye had (2.4%) ciliary block. Most shallow anterior chambers can be effectively improved after appropriate treatment.

Conclusions: Shallow anterior chamber can be caused by a variety of reasons, mainly by excessive filtration. We should actively take reasonable measures to improve the symptom and try to avoid its occurrence.
