Abstract Details



Purpose:

Adult-onset foveomacular vitelliform dystrophy (AFVD) is a rare disease characterized by a round subretinal deposit of yellowish material located in the macular area but the exact location of the vitelliform material has not been fully elucidated. Although the features of AFVD have already been evaluated by optical coherence tomography (OCT), a concomitant case of AFVD and diabetic cystoid macular edema has not been reported before. This poster aimed to report a rare association of AFVD with diabetic cystoid macular edema.

Setting:

Ulucanlar Eye Training and Research Hospital.

Methods:

A case report. 55 year-old female with an unusual appearance on spectralis OCT was presented.

Results:

The patient's visual acuities were 20/40 with -1.00 spherical diopters (D) in the right eye and 20/50 with -2.50 spherical D in the left eye. While the anterior segment examinations exhibited nuclear sclerosis for both eyes, the fundus examination of the patient demonstrated a round, elevated yellowish lesion centreed by a pigmented spot, widespread intraretinal microaneurysms and dot-blot haemorrhages with a small number of hard exudates in the both eyes. OCT scans of both eyes disclosed that the foveal retina was raised by a hyperreflective material which was located between the retina pigment epithelium and the photoreceptor layer with a persistent posterior hyaloid attachment exerting adhesion on the fovea in the both eyes. Moreover, multiple hyperreflective retinal dots which had shadowing effects and cystoid macular edema without subretinal fluid were revealed in OCT images. Additionally, fundus autofluorescence (FAF) imaging demonstrated that the vitelliform lesions were hyper-autofluorescence in the fovea which were compatible with accumulation of lipofuscin while the haemorrhages were seen as hypo-autofluorescence dots in both eyes.

Conclusions:

Diabetic cystoid macular edema may rarely accompany AFVD; OCT and FAF are helpful diagnostic imaging techniques to identify this condition.
