CENTRAL VISUAL PHENOMENA AS CLUES TO VITREOMACULAR TRACTION IN PATIENTS WITH NORMAL FUNDUS OCULI.

Purpose: To report two cases where the primary visual complaints were central visual phenomena, with normal fundus biomicroscopy.
Methods: History and clinical examination, fundus autofluorescence, and spectral domain-optical coherence tomography.
Results: The authors report 2 patients, a 66-year-old woman and a 77-year-old woman, who complained of a central visual disturbance in one eye. Best-corrected visual acuity was normal. Ophthalmoscopy in the first case was unremarkable and showed minimal retinal pigment epithelial mottling in Case 2. Spectral domain-optical coherence tomography revealed vitreomacular traction with foveal distortion in both eyes, associated with small cysts in the inner retinal layers and in one patient disruption of photoreceptors.
Conclusion: Central visual phenomena are important clues for central vitreomacular traction, even in the presence of a normal fundus examination. The authors highlight the importance of performing spectral domain-optical coherence tomography evaluation in this setting before considering neurologic or systemic causes.
