  In [2], the authors develop a global correspondence between immersed weakly
horospherically convex hypersurfaces $\phi:M^n \to \mathbb{H}^{n+1}$ and a
class of conformal metrics on domains of the round sphere $\mathbb{S}^n$. Some
of the key aspects of the correspondence and its consequences have dimensional
restrictions $n\geq3$ due to the reliance on an analytic proposition from [5]
concerning the asymptotic behavior of conformal factors of conformal metrics on
domains of $\mathbb{S}^n$. In this paper, we prove a new lemma about the
asymptotic behavior of a functional combining the gradient of the conformal
factor and itself, which allows us to extend the global correspondence and
embeddedness theorems of [2] to all dimensions $n\geq2$ in a unified way. In
the case of a single point boundary $\partial_{\infty}\phi(M)=\{x\} \subset
\mathbb{S}^n$, we improve these results in one direction. As an immediate
consequence of this improvement and the work on elliptic problems in [2], we
have a new, stronger Bernstein type theorem. Moreover, we are able to extend
the Liouville and Delaunay type theorems from [2] to the case of surfaces in
$\mathbb{H}^{3}$.
