Can you tell if Latisse is beginning to cause ‘sunken eyes’ before it progresses? Is this more likely in older women?

I am considering using Latisse, but after getting ptosis from Botox, I am nervous. I’m 68. Is there a way to measure or assess your eyes so you can tell if they are becoming sunken before it gets bad? Do they return to normal? Is this side effect more likely with older age or with any other characteristic, such as skin or eye coloring?
