Infrared and fundus autofluorescence imaging in eyes with optic disc pit maculopathy

To characterize the infrared (IR) and fundus autofluorescence (FAF) images of eyes with optic disc pit maculopathy.

A retrospective non-comparative study of three patients with optic disc pit maculopathy who were followed by optical coherence tomography (OCT) and retinal angiography (Heidelberg retina angiograph 2) before and after vitreous surgery without laser photocoagulation.

The areas of serous retinal detachment and inner retinal schisis were dark in the IR and FAF images preoperatively; and they changed to brighter areas following reattachment of the retina. There was an increase in the granular hyperfluorescence in the FAF images accompanied by an increase in the number of subretinal precipitates. OCT showed a thickening of the photoreceptor outer segments. The outer retinal layer defect initially appeared bright in the IR images and hypofluorescent or hyperfluorescent in the FAF images. The outer retinal layer defect became larger with a reduction of the outer retinal schisis and increased retinal detachment, but then became smaller with the resolution of the retinal detachment. All cases had a resolution or reduction of the retinal detachment and retinal schisis after the vitrectomy.

The IR and FAF images in eyes with optic disc pit maculopathy reflect the changes in the inner and outer retinal layers corresponding with the stage of recovery of the disease.
