INTRODUCTION: Primary congenital glaucoma is a rare ocular disorder that is responsible for 0.01%-0.04% of total blindness worldwide. The goal of congenital glaucoma management is to allow for proper development of the immature visual system by controlling intraocular pressure. Medical therapy usually provides a supportive role to temporarily reduce intraocular pressure, but patients typically require iridocorneal angle surgery to facilitate aqueous humor outflow. In this report, we describe the use of minimally invasive ab interno Kahook Dual Blade trabeculectomy for treatment of primary congenital glaucoma. CASE DESCRIPTION: A 13-month-old male with bilateral primary congenital glaucoma due to a loss of function TEK mutation. He had bilateral findings of elevated intraocular pressures, buphthalmos, Haab's striae, photophobia, and myopia. Over the course of 6 weeks, three ab interno trabeculectomies with a Kahook Dual Blade were performed in the patient's left eye and one in the patient's right eye. After 3 months, intraocular pressures while receiving pressure reducing ophthalmic drops bilaterally reduced from 43 to 21 mmHg in the right eye after a single surgery and from 44 to 34 mmHg in the left eye after three surgeries, eventually requiring glaucoma drainage implant placement. There were no complications. CONCLUSION: Ab interno Kahook Dual Blade Trabeculectomy is a minimally invasive and potentially successful procedure for the treatment of congenital glaucoma. The safety profile of minimally invasive glaucoma surgery warrants consideration for congenital glaucoma patients, as they usually require iridocorneal angle surgery because pharmacologic therapy is typically inadequate.
