Transient shallow anterior chamber induced by supraciliary fluid after vitreous surgery.
OBJECTIVE
To report the mechanism of transient shallow anterior chamber after vitreous surgery for proliferative diabetic retinopathy.


METHODS
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.


CONCLUSIONS
The shallow anterior chamber in this patient was caused by supraciliary fluid after vitreous surgery.
