[The clinical features of retinal detachment with congenital choroidal coloboma].
OBJECTIVE
To approach the clinical features of retinal detachment with congenital choroidal coloboma and seek better surgical methods to improve the effect of treatment.


METHODS
Vitreoretinal surgery was performed on eight patients of retinal detachment with choroidal coloboma. During surgery by using an operating microscope with high magnification and endoillumination, we searched for retinal break(s) located in the colobomatous area, looked into the condition of posterior hyaloid area, status of coloboma, treatment was given accordingly, and finally silicone oil tamponade was performed.


RESULTS
Retina was reattached anatomically after operation in all cases, and their visual acuities improved.


CONCLUSIONS
The type of retinal detachment is caused by the retinal break inside the coloboma. The breaks located at the edge of the detachment within the coloboma, ectatic sclera at the colobomatous region, without posterior vitreous detachment are the features of the retinal detachment with congenital choroidal coloboma. Complete vitrectomy with method to create chorioretinal adhesion around the coloboma and silicone oil tamponade provide an effective treatment for this complicated type of retinal detachment.
