Metamorphopsia

A 50-year-old woman was examined in for complaints of metamorphopsia in her left eye. Her uncorrected visual acuity (VA) was 4/4 on Early Treatment Diabetic Retinopathy Study charts (ETDRS), on the retina of her left eye white, prominent, partially calcified tumour 1 disc diameter in diameter, 1,5 disc diameter from the foveola was detected on the retina. In the macular region of both eyes, parafoveal greying with crystalline deposits and changes in retinal vasculature were visible. Following examinations were done fluorescein angiography (FA), B-scan ultrasound, spectral domain optical coherence tomography (SD-OCT) including photo documentation. FA showed partial hyper-fluorescence of mulberry-like surface of the tumour. Parafoveally in both eyes, leakage from parafoveal telangiectasia was apparent. SD-OCT showed cystoid space in the macular region of both eyes as well as changes in inner and outer photoreceptor segment junction in left. Ultrasound examination of the tumour detected solid, highly echogenic prominent tumour with high reflectivity and acoustic shadow.
