| Summary: |
Purpose: The aim of
this study is to present a case of 14-years old patient
with enhanced S-cone syndrome (ESCS).
Methods: The routine ophthalmologic examination,
eye fundus photographs, color vision, kinetic visual
field, static perimetry 30-2 B-Y and W-W, and flash ERG
were performed.
Results: The ESCS diagnosis was based on the
clinical evaluation, static perimetry and ERG.
In comparison with the M and L-cones the greater
sensitivity of S-cones was noted in the automated static
perimetry. The ERG showed characteristic similar
waveforms in scotopic and photopic conditions with white
single flash stimuli (0 dB).
Conclusions: The enhanced S-cone syndrome is a
slowly progressive disease. The diagnosis is very
important for patient because of the more favorable
prognosis in comparison with the autosomal recessive
retinitis pigmentosa. The ERG is a very useful test for
ESCS diagnosis establishing. |
