A unusual occurrence of bilateral choroidal effusion following an XEN45 implantation was the subject of this study. The implantation of the ab interno XEN45 device in the right eye of an 84 years old man with primary open angle glaucoma went smoothly. Hypotony and serous choroidal detachment made the early postoperative period more challenging, however they were both treated and cured with the help of cycloplegic drops and steroids. The identical procedure was performed on the second eye eight months later, and choroidal detachment necessitated transscleral surgical drainage.
Conclusions: This case demonstrates the value of meticulous postoperative monitoring and prompt intervention in the setting of XEN45 implantation and raises the possibility that choroidal effusion in one eye may be a risk factor for choroidal effusion in the other eye.
