The pathogenesis of the sensory retinal detachment of the macula associated with congenital pit of the optic nerve remains controversal. Based on our cases and the cases reported in literature, we propose a management plan for macular retinal detachment associated with optic nerve pit.


In this retrospective study ten eyes were treated for progressive visual loss. Treatment modalities were different depending on the time period: laser photocoagulation (to the juxtapapillary region) alone, laser combined with intraocular gas injection (C3 F8), laser combined with vitrectomy and intraocular gas tamponnade (S F6, C3 F8), laser combined with vitrectomy and temporary silicone oil tamponade.


The follow-up period ranged between one and five years (mean follow-up thirty three months). We had eight successes and two definitive failures (an old macular detachment treated only by one laser session, and a young girl who had not kept the prone position after gas injection). In the group of six eyes treated by laser alone, only two retinal treatments were directly successfully treated; in three other eyes, the detachment recurred and was treated with success in a second step by a gas injection; the sixth eye is the first definitive failure (old detachment). In the five eyes treated by laser combined gas injection with or without pars plana vitrectomy (including three failures of laser alone), the retina remained attached in four eyes during the follow-up period; the sixth eye was the second definitive failure (the young girl). In the both eyes treated by vitrectomy and silicon oil injection, the retina has flattened.


The results suggest that laser photocoagulation alone is not so efficient and that vitrectomy is not necessary with gas injection. Complete resorption of subretinal fluid occurred in eight eyes: two with laser photocoagulation alone, and six with a long term tamponnade combined with a peripapillary laser photocoagulation. In first treatment, this technique (laser with tamponade) is a valuable approach to manage serous macular detachment associated with optic nerve pit.
