Oct findings in torpedo maculopathy.

BACKGROUND

Torpedo maculopathy, also called solitary hypopigmented nevus, is a rare though benign disorder. To our knowledge, there are no previous optical coherence tomography (OCT) descriptions in the literature.

METHODS

Results of ophthalmologic examinations (including retinography, OCT, and visual field testing) for 2 girls aged 12 years and 13 years throughout 5 years of follow-up were reviewed.

RESULTS

In both cases, anterior and posterior segment evaluation was unremarkable except for the presence of a flat, fishtail-shaped, hypopigmented lesion temporal to the macula, pointing to the fovea. In case 1, OCT disclosed faint thinning of the retina above the lesion especially in the outer retina and hyperreflectivity of the retinal pigment epithelium (RPE) associated with a posterior hyperreflective signal deep in the choroids. In case 2, OCT showed an atrophic retina with reduced thickness probably due to the absence of the photoreceptor layer. Shallow serous neurosensory detachment, increased RPE reflectivity, and higher penetration of light to the choroid were also evident.

CONCLUSION

In both cases of torpedo maculopathy studied by OCT, we found a variable amount of retinal degeneration, and a serous retinal detachment was found in one case.
