Surgical management of retinal detachments related to coloboma of the choroid

Ophthalmology. 1998 May;105(5):804-9. doi: 10.1016/S0161-6420(98)95018-7.


Objective: This study aimed to develop a rationale for the management of retinal detachments related to choroidal coloboma and to study the outcome of their management.

Design: The study design was a retrospective study.

Participants: A total of 85 eyes of 81 patients with retinal detachments related to coloboma of the choroid participated.

Intervention: All eyes underwent pars plana vitrectomy with internal tamponade using silicone oil (80 eyes) or perfluropropane gas (5 eyes). Behavior of the retina on fluid-air exchange was used to guide the further steps of surgery. Endolaser was performed along the coloboma border. Silicone oil was removed in 80% of eyes. The main outcome measures were retinal reattachment and visual recovery.

Results: Recurrent retinal detachment occurred in 16.3% of silicone oil-filled eyes and 60% of gas-filled eyes. After silicone oil removal, 15.6% of eyes had recurrent retinal detachment. After a mean follow-up of 13.4 months, 81.2% of eyes had attached retina and 69.4% recovered equal to or better than 10/200 visual acuity.

Conclusion: Retinal detachment secondary to coloboma of choroid is treated best by pars plana vitrectomy along with silicone oil tamponade. Gas tamponade has limited indications. Clinical evaluation of the extent of retinal detachment within the colobomatous area and the behavior of the retina on fluid-air exchange help the authors understand the pathogenesis of the retinal detachment and plan a rational therapy.
