Hi Loubear, Thanks for writing to us. What you have mentioned sounds like a Haematoma, with ecchymosis ( purplish skin post trauma). Keep an eye on the vision, and with a dose of oral anti inflammatory drugs, your swelling should come down.if there is any open cuts, you need a prescribed antibiotic to avoid infection. If your vision is dropping and your swelling is increasing in size in the next 3 days, the have a consultation. Although its not an emergency, an eye examination is needed after your swelling to rule out any indirect injury to your inside layers of the eye. So take care.
