We present diagnostic difficulties associated with macular lesions giving symptoms of central visual field distortions due to retinal and choroidal diseases different than age related macular degeneration (AMD).
Aim: To analyze causes of metamorphopsia similar to that occurring in AMD.
Material and methods: Patients presented for Preferential Hyperacuity Perimetry (PHP) examination due to the central visual field distortion. In cases of abnormal PHP result, we performed visual acuity testing and stereoscopic examination of the eye fundus. In selected cases optical coherence tomography (OCT), fluorescein angiography (FA) and indocyanine green chorioangiography (ICG) were performed. Following these examinations the decision about further management was made. Analyzed cases demonstrate the need to correlate the PHP examination, which objectifies visual field distortions symptoms with stereoscopic eye fundus examination and additional examinations of retina and choroid including OCT, FA and ICG.
