Advantages:

To evaluate the features of myopic foveoschisis with Fourier-domain optical coherence tomography (FD-OCT).

Methods:

Eyes with myopic foveoschisis were assessed with FD-OCT (Topcon Inc, Paramus, NJ).

Effectiveness / Safety:

Five eyes of 5 patients were analyzed. The patients were seen at the Singapore National Eye Centre from June 2008 to April 2009. There were 2 males and 3 females. The mean age was 61.8 years. Mean refractive error was -12.9 diopters with mean axial length of 30.2mm. Best corrected pre-operation visual acuity ranged from 6/6 to 6/30. The mean pre-operation central retinal thickness (CRT) was 470.6um with presence of foveal detachment in 1 eye. There was loss of foveal blunting (3). Areas of schisis included extrafoveal area (1), foveal and macular (2), foveal, macular and extramacular (1). Irregularity of intraretinal layers was seen in 4 eyes. Cystoid changes occurred at the foveal and inferior macula (2); and inferior macula (2). Lamellar holes occurred at foveal (1) and extrafoveal (1) part of the macula. The inner and outer photoreceptor segments were present in 3 eyes and absent in 2 eyes. Vitreomacular traction was seen at the superior third, central third and inferior third of the macula in 1 eye; and at inferior third of the macula in 4 eyes.

Take home message:

FD-OCT enables a detailed and extensive assessment of the macula in eyes with myopic foveoschisis.
