is there any difference between the 2D continuous and discrete gabor filter when it comes to MATLAB implementation

I want to know the difference between the 2D continuous and discrete gabor filter when it comes to matlab implementation. I found many files related to 2D gabor filter on mathworks file exchange but I am unable to find any file related to 2D continuous gabor wavelet. I want to use continuous gabor filter to enhance blood vessels in retinal images. Please guide me.
