With red bloodshot eyes, it is important to identify exactly what is causing the condition to appear so that treatment can be targeted. For example, for patients with conjunctivitis, topical antibiotic eye drops can be used, and for patients with sclicitis or iritis, topical hormonal and non-steroidal anti-inflammatory eye drops are required. Patients with glaucoma who have red blood in their eyes should use eye drops to lower their eye pressure according to their condition, and surgery may be considered if necessary.
