Purpose: To evaluate structural retinal changes and macular function by a combined spectral domain optical coherence tomography/scanning laser ophthalmoscope (OCT/SLO) microperimetry device in choroideremia carriers.
Methods and materials: Ten choroideremia carriers were included in the study. All subjects had a complete ophthalmic examination in addition to Goldmann kinetic visual fields, OCT and microperimetry testing on a commercially available Spectral Domain (SD) OCT/SLO combination system.
Results: Microperimetry results demonstrated focal areas of threshold abnormalities in 50% of the subjects. OCT findings show subtle retinal pigment epithelium (RPE) irregularities with attenuation more pronounced outside the macular region.
Conclusions: Long term follow up with microperimetric testing could be useful in monitoring any progressive loss of retinal function in choroideremia carriers.
