Objective

Prerequisite of a correct laser-scanning polarimetry (GDx) of the optic disc is the estimation of the polarizing properties of the cornea. The corneal influence may be estimated by the polarizing image of the perifoveal Henlesche fibre layer. This estimation is not possible in eyes with certain macular diseases. Aim of the present study was to determine the influence of sereous detachment of the macula on the perifoveal polarimetric image.

Methods

Ten eyes with serous detachment of the macula underwent GDx and optical coherence tomography (OCT) imaging. The visualisation of the perifoveal polarimetric image was judged on a scale of 1 (very good) - 6 (not recognizable). The heighth of the detachment was measured on the OCT image.

Results

Serous detachments of the macula up to 484μm (normal 120 - 190μm) allow a good visualisation of the perifoveal polarimetric image (scale 1-2). Detachments exceeding 500μm or detachments accompanied by a cystoid macular edema led to a distortion of the perifoveal polarimetric image (scale >3).

Conclusions

Serous detachment of the macula without alterations of the retinal surface allow a good visualisation of the perifoveal polarimetric image and thus an estimation of the corneal polarizing properties.
