While isotropic models can successfully reproduce a range of Ly$\\alpha$ observables, the correspondence between the model and actual physical parameters remains uncertain. We investigate the effect of anisotropies of Ly$\\alpha$ escape using a simplified setup: a hole (fractional size $\\tilde s$) within a semi-infinite slab with constant column density. Due to the slab's high line-centre optical depth ($\\tau_0\\gtrsim 10^{5-6}$), most photons should escape through the empty channel.
