This paper reveals optical dromions and domain walls to (2 + 1)-dimensional nonlinear Schrodinger's equation in presence of higher order dispersion terms, together with Kerr law nonlinearity. Four notable integration algorithms, via, the sine-cosine method, the simplest equation method, the modified Kudryashov method and the unified Riccati equation expansion have been applied with grand success. The revealed solutions come with their respective existence criteria that are also presented.
