Thanks for reaching out about your Oscar and including photos, but difficult to see the HLLE lesions due to too dark. The eye looks terrible and systemic antibiotics are recommended at the least. A veterinary visit is highly recommended to clean the wound and provide other possible treatments. The water quality must be kept pristine (pH, ammonia, nitrites, nitrates) to assist recovery. Antibiotics added to the water do not penetrate into the body, nor do fresh water fish drink, since osmotically water enters over mucous membranes (gills, mouth, skin) and antibiotics do not cross this barrier. HLLE causes can be multi-factorial including water quality, bacteria, parasites, carbon particles in activated charcoal (filters), low vitamin C, etc. Check and correct water quality, replace existing food if older than two months (vitamin C degrades quickly), see a veterinarian with fish experience. Good luck.
