Abstract

Introduction: Choroidal neovascularization (CNV) is a rare complication after laser photocoagulation for central serous chorioretinopathy (CSCR).That’s why , little is known about its management. Anti-VEGF therapy has emerged as the treatment of choice in patients with CNV. We report a case of a patient who developed iatrogenic CNV after having argon laser photocoagulation for a CSCR, treated with intravitreal injections of Bevacizumab.
Aim: The goal of our paper is to show the efficacy and safety of the intravitreal injections of antiVEGF and discuss the alternative of argon laser photocoagulation to avoid complications.
Case presentation:  A 35-year-old pregnant woman diagnosed in August 2014 with an acute CSCR in the right eye. The patient was treated by a focal photocoagulation of the leakage point . In December 2015, she was complaining of metamorphopsia in the same eye .The BCVA was 10/10 in the right eye , and the funduscopic examination showed agrayish-white neovascular membrane, which corresponded to the area of the previous photocoagulation.The fluorescein angiography , OCT and the OCT angiography demonstrated the choroidal neovascular membrane .The patient received 3 intravitreal injections of Bevacizumab at monthly intervals in the right eye.The patient was followed-up at regular intervals and she became asymptomatic during three years.
Conclusion: Choroidal neovascualrization may be an iatrogenic complication after argon photocoagulation in CSCR. Intravitreal injections of anti VEGF appear to be a promising treatment option for iatrogenic CNV due to photocoagulation.
