I work on fundus image , bwareaopen() function removes all connected components fewer than P pixels. But in my image I need to remove all the regions which have more than 11 pixels how can I do so? And how can I calculate the metrics of each region and eliminate the structures having metrics less than 0.95?

So P=11, right? Did you try this:
binaryImage = bwareaopen(binaryImage, 11);
Regarding "metrics", I think you need to do a spatial calibration, and I attach my demo for that. So then use regionprops() and multiply linear measurements by the spatial calibration factor and area measurements by the spatial calibration factor squared.

You can do what Image Analyst mentioned:
binaryImage_out = bwareaopen(binaryImage_in, 11);
Later, subtract binaryImage_in and binaryImage_out.

binaryImage = binaryImage - bwareaopen(binaryImage, 11);
