To explore vitreoretinal pathologies and their longitudinal changes visible on handheld optical coherence tomography (OCT) of young children with familial exudative vitreoretinopathy.
The authors retrospectively analyzed handheld OCT images for vitreoretinal interface and retinal abnormalities and optic nerve head (ONH) elevation.
From 26 eyes of 16 children (mean age 32 months) with familial exudative vitreoretinopathy, 10 had ONH dragging on photographs, and in these, handheld OCT revealed temporal and anterior retinal displacement, prominent vitreopapillary adhesion or traction, and retinal nerve fiber layer thickening at ONH margins with adjacent retinal elevation. Despite a nearly normal photographic appearance, handheld OCT revealed ONH elevation with vitreopapillary traction (6/16 eyes), ONH edema (1/16 eye), and retinal vascular protrusion (5/16 eyes). Handheld OCT–visualized vitreous abnormalities (18/26 eyes) were more prevalent at higher stages of disease. Handheld OCT–visualized elevation of ONH and the retina worsened over time in nine eyes and improved in 5/6 eyes after vitrectomy.
Handheld OCT can detect early ONH, retinal, and vitreous changes in eyes with familial exudative vitreoretinopathy. Contraction of strongly adherent vitreous in young patients with familial exudative vitreoretinopathy appears to cause characteristic ONH dragging and tractional complications without partial posterior vitreous detachment. Vitreopapillary dragging may be visible only on OCT and may progress in the absence of obvious retinal change on conventional examination.
In addition to retinal traction by the peripheral fibrovascular membrane, strong anteroposterior traction by contraction of strongly adherent vitreous is a contributing factor during the progression of familial exudative vitreoretinopathy in infants.
