Aim: To describe clinical and prognostic characteristics of irido-chorio-retinal colobomas through 3 cases.
Observations:The average age of the three patients was 12,66 years. The sex-ratio was 0,5 with female predominance (66,7%). The three patients were admitted for a severe visual impairment and automated refraction test did not work for the two eyes. They all presented a nuclear cataract and an inferior iris coloboma for the two eyes. All the patients had bilateral chorio-retinal colobomas including papilla. The pediatric examination found one case of cryptorchidism but was normal for the two other patients. B-scan ocular ultrasound found a chorio-retinal defect facing the optical nerve for one patient. We managed the low vision and prescribed sunglasses to avoid photophobia. A cataract surgery was realized, and we also gave a genetic counselling. No patient had a retinal detachment.
Discussion & Conclusion:Chorio-retinal coloboma is a rare and serious disease, because of its evolution and complications. It requires early, appropriate, and multidisciplinary treatment.
