[Ultrasound biomicroscopy as a criterium of functional assessment of the supra-choroidal cleft after chamber angle surgical interventions].

BACKGROUND

The new technique of ultrasonic biomicroscopy provides detailed information about the extension and width of suprachoroidal clefts during the follow-up period after cyclodialysis ab interno.

PATIENTS AND

METHODS

We examined a group of 9 patients suffering from dysgenetic glaucoma and secondary glaucoma. Ultrasonic biomicroscopy was performed before and after cyclodialysis ab interno. The results were compared to those of gonioscopy.

RESULTS

These examinations revealed that even cyclodialysis clefts which appeared to be closed by gonioscopy were still open. This was proven by a broad choroidal cleft in the cyclodialysis area.

CONCLUSIONS

Thus, ultrasonic biomicroscopy is a means of checking the outcome of cyclodialysis ab interno and may influence the indications for further surgical procedures.
