Long-term follow-up in enhanced s-cone syndrome.
OBJECTIVE
To report the long-term follow-up of a case of enhanced S-cone syndrome (ESCS).


METHODS
Retrospective chart review.


RESULTS
The patient was misdiagnosed with atypical retinitis pigmentosa at 17 years of age. Twenty-seven years of follow-up showed slow deterioration but relative preservation of vision. The most striking clinical feature was the formation of a ring of heavy round pigment clumping around the vascular arcades. Electroretinogram was reported as extinguished in advanced stages of the condition. Genetic testing revealed the most common mutation of the NR2E3 gene reported in the Goldmann-Favre syndrome/ESCS entity.


CONCLUSIONS
Visual acuity can be relatively preserved over the course of ESCS. In advanced stages, genetic testing can be a valuable diagnostic tool.
