Presentation
Facial trauma and incidentally left eye coloboma and right eye staphyloma were found.
Patient Data
The left eye has asymmetrically and remarkably increased anterior-posterior length up to 30mm and posterior and temporal uveo-scleral layer thinning. Focal bulge and thinning of the uveo-scleral layer on the posterior temporal side of the right eye are also seen. Note also low-width optic nerves on both sides are more prominent on the left.
Case Discussion
The case illustrates left eye globe posterior segment coloboma or chorioretinal coloboma but in most cases, the chorioretinal coloboma is bilateral and involves the anterior segment of the eye that is simply called coloboma. The normal anterior-posterior length of the eye globe is up to 22mm but in chorioretinal coloboma is usually more than 26mm. The staphyloma in the posterior temporal side of the right eye globe uveo-scleral layer is also noted. The staphyloma is almost always in the posterior segment of the eye globe and temporal side of the optic disc as in this case.
