Short-term results of ab-interno trabeculotomy using Kahook Dual Blade in patients with primary congenital glaucoma.

The aim of this study is to present the results of ab-interno trabeculotomy using Kahook Dual Blade in patients with primary congenital glaucoma. An ab-interno trabeculotomy using a dual blade device was performed in three eyes of two patients with the diagnosis of primary congenital glaucoma. One of them in the left eye and the other patient in both eyes. In the first patient, an adequate response was achieved after the intraocular pressure reduced from 36 mmHg to 14 mmHg. The second patient did not respond adequately to the procedure, and high intraocular pressure levels persisted in both eyes after the procedure. The indication of Kahook Dual Blade ab-interno trabeculotomy in primary congenital glaucoma must be cautious and more studies are needed to establish its efficacy and the best indications. Seems that this procedure should not be indicated for primary congenital glaucoma treatment.
