Vitreoretinal surgery for retinal detachment in retinochoroidal colobomata.
OBJECTIVE
To report the management and outcome of retinal reattachment surgery in retinochoroidal coloboma.


METHODS
Four patients with retinochoroidal colobomata presented to the Bristol Eye Hospital (a UK tertiary referral center for vitreoretinal surgery) with retinal detachment.


METHODS
All were type II colobomatous detachments (three patients with type IIB, one patient with type IID). All eyes underwent vitrectomy with endolaser and/or cryotherapy and three eyes underwent scleral buckling. Two eyes had internal tamponade with gas (SF6, C3F8) while the other two had silicone oil. Endolaser was applied over healthy retinal pigment epithelium.


RESULTS
At last follow-up, all (100%) remained attached, with no recurrences. Three patients achieved visual acuity of 6/120 or better and were able to perform satisfactory near work with appropriate magnifiers. The last patient began with hand movement vision and retained similar vision but subjectively felt more navigational.


CONCLUSIONS
Good anatomic and functional outcomes can be achieved in this patient group with combined vitrectomy with or without scleral buckling surgery. Endolaser retinopexy is effective over healthy RPE at the margin of the coloboma combined with either gas or oil internal tamponade.
