my sister has sore eyes for 2 weeks already. the doctor gave her medication (antibiotics eye drops), but it didn't get better. now doc advised she has got a serious case of conjunctivitis resulting in growth of membrane. the membrane caused abrasion and scratched the corneal. she is feeling pain in her eye and has to keep it covered.
doc said that it would take around 3 weeks to heal. meantime, she has to visit the doc every 2 days to remove the membrane. is this normal ? the redness hasn't subsided. should i be concerned ?
