Hello,
What she has developed,is a bleed, and now it appears like it's resolving. It's going to turn yellow,and then slowly to normal colour. Start using moxi eye drops (antibiotic) to prevent any further infection.
Next Steps
Rule out hypertension (highBP) . If she already is taking tablets for hypertension, check to see if it's under control. It's going to remain bright red for another week or so. Nothing to worry as long as blood pressure is normal.
