Purpose:
To report the mechanism of transient shallow anterior chamber after vitreous surgery for proliferative diabetic retinopathy.
Method:
Using ultrasound biomicroscopy, we examined a patient with transient shallow anterior chamber after vitreous surgery for proliferative diabetic retinopathy.
Results:
On the day after surgery, slit-lamp examination disclosed a shallow anterior chamber that persisted for 1 week and deepened thereafter. Ultrasound biomicroscopy 5 days postoperatively disclosed a narrow angle in the peripheral anterior chamber and supraciliary fluid. At 14 days postoperatively, suprachoroidal fluid could not be detected, and the angle was wide.
Conclusion:
The shallow anterior chamber in this patient was caused by supraciliary fluid after vitreous surgery.
