In this paper, firstly, we define the concepts of strongly lacunary convergence, strongly lacunary $\mathcal{I}$-convergence and strongly lacunary $\mathcal{I}^{\ast}$-convergence of double sequence of functions, and also we investigate the relations between them. Then, we define the concepts of strongly lacunary Cauchy sequence, strongly lacunary $\mathcal{I}_2$-Cauchy sequence and and strongly lacunary $\mathcal{I}^{\ast}_2$-Cauchy sequence of functions, and also we investigate the relations among strongly lacunary $\mathcal{I}_2$-convergence, strongly lacunary $\mathcal{I}_2$-Cauchy sequence and strongly lacunary $\mathcal{I}^{\ast}_2$-Cauchy sequence.
