This 57YO male underwent successful vitrectomy surgery 8 years earlier for rhegmatogenous retinal detachment (RRD). Vision is now 20/40.
The detachment was caused by a retinal break associated with an inferior choroidal coloboma. The margins of the coloboma are surrounded by confluent depigmented scarring from prior laser photocoagulation. Prophylactic peripheral laser was also applied intraoperatively.
Learning Points:
Choroidal colobomas arise from incomplete closure of the embryonic fissure during the second month of embryonic development.
Patients are at lifelong risk of rhegmatogenous retinal detachment due to breaks in the overlying thinned retina.
