Oedipus walks in on Jocasta hanging their dead after she killed herself. Line 380 "She was hanging there with a noose around her neck."
Oedipus stabs his eyes with Jocasta's brooches lines 384-387 "he tore the brooches from her robe and raised them into the sockets of his eyes. He shouted aloud, "no longer shall these eyes such agony as this!"
Oedipus is leaving so he is saying goodbye to his daughter's lines 554, "let me touch them and let me weap. Oh creon, let your noble heart break. I have no eyes. But I have hands. Let me touch them, Let me feel what i once had."
