Chorioretinal coloboma in a patient with pancreas divisum: Clinical and imaging features

Purpose: To report the case of a 61-year-old woman with pancreas divisum and an asymptomatic chorioretinal coloboma in its 2 forms: complete and partial. Methods: Case report. Results: Dilated fundus examination and photograph revealed a complete and partial coloboma in the right eye. Swept-source optical coherence tomography and swept-source optical coherence tomography angiography (SS-OCTA) were performed. Swept-source optical coherence tomography angiography disclosed the complete coloboma as a black, round, avascular area surrounded by normal vascular tissue in every plexus (i.e., superficial, deep, and choriocapillary). Although irregular and attenuated, the vascular network of the partial coloboma was appreciable in each layer, indicating some degree of vascular preservation. Conclusions: Chorioretinal coloboma has been linked to several ocular and systemic conditions. To our knowledge, no association between coloboma and pancreas divisum has been reported. In addition, chorioretinal coloboma has not been previously characterized by means of SS-OCTA.
