The IC was a tradition since the beginning of the Church--The catholic Church simply codified it and made it Dogma, but it was always part of the Holy Tradition and understood since the founding of the Church. Writings of the Church Fathers, even the Greek Fathers supported it. So why does the EO oppose making it dogma?
Mary herself said it, that is enough for me
But Besides that:
Patristic writings on Mary's purity abound.
St. John Damascene (Or. i Nativ. Deip., n. 2) esteems the supernatural influence of God at the generation of Mary to be so comprehensive that he extends it also to her parents. He says of them that, during the generation, they were filled and purified by the Holy Ghost, and freed from sexual concupiscence. Consequently according to the Damascene, even the human element of her origin, the material of which she was formed, was pure and holy. This opinion of an immaculate active generation and the sanctity of the "conceptio carnis" was taken up by some Western authors; it was put forward by Petrus Comestor in his treatise against St. Bernard and by others. Some writers even taught that Mary was born of a virgin and that she was conceived in a miraculous manner when Joachim and Anne met at the golden gate of the temple (Trombelli, "Mari SS. Vita", Sect. V, ii, 8; Summa aurea, II, 948. Cf. also the "Revelations" of Catherine Emmerich which contain the entire apocryphal legend of the miraculous conception of Mary.
From this summary it appears that the belief in Mary's immunity from sin in her conception was prevalent amongst the Fathers, especially those of the Greek Church. The rhetorical character, however, of many of these and similar passages prevents us from laying too much stress on them, and interpreting them in a strictly literal sense. The Greek Fathers never formally or explicitly discussed the question of the Immaculate Conception.

But Besides that:
Patristic writings on Mary's purity abound.
- The Fathers call Mary the tabernacle exempt from defilement and corruption (Hippolytus, "Ontt. in illud, Dominus pascit me");
- Origen calls her worthy of God, immaculate of the immaculate, most complete sanctity, perfect justice, neither deceived by the persuasion of the serpent, nor infected with his poisonous breathings ("Hom. i in diversa");
- Ambrose says she is incorrupt, a virgin immune through grace from every stain of sin ("Sermo xxii in Ps. cxviii);
- Maximus of Turin calls her a dwelling fit for Christ, not because of her habit of body, but because of original grace ("Nom. viii de Natali Domini");
- Theodotus of Ancyra terms her a virgin innocent, without spot, void of culpability, holy in body and in soul, a lily springing among thorns, untaught the ills of Eve, nor was there any communion in her of light with darkness, and, when not yet born, she was consecrated to God ("Orat. in S. Dei Genitr.").
- In refuting Pelagius St. Augustine declares that all the just have truly known of sin "except the Holy Virgin Mary, of whom, for the honour of the Lord, I will have no question whatever where sin is concerned" (On Nature and Grace 36).
- Mary was pledged to Christ (Peter Chrysologus, "Sermo cxl de Annunt. B.M.V.");
- it is evident and notorious that she was pure from eternity, exempt from every defect (Typicon S. Sabae);
- she was formed without any stain (St. Proclus, "Laudatio in S. Dei Gen. ort.", I, 3);
- she was created in a condition more sublime and glorious than all other natures (Theodorus of Jerusalem in Mansi, XII, 1140);
- when the Virgin Mother of God was to be born of Anne, nature did not dare to anticipate the germ of grace, but remained devoid of fruit (John Damascene, "Hom. i in B. V. Nativ.", ii).
- The Syrian Fathers never tire of extolling the sinlessness of Mary. St. Ephraem considers no terms of eulogy too high to describe the excellence of Mary's grace and sanctity: "Most holy Lady, Mother of God, alone most pure in soul and body, alone exceeding all perfection of purity ...., alone made in thy entirety the home of all the graces of the Most Holy Spirit, and hence exceeding beyond all compare even the angelic virtues in purity and sanctity of soul and body . . . . my Lady most holy, all-pure, all-immaculate, all-stainless, all-undefiled, all-incorrupt, all-inviolate spotless robe of Him Who clothes Himself with light as with a garment . . . flower unfading, purple woven by God, alone most immaculate" ("Precationes ad Deiparam" in Opp. Graec. Lat., III, 524-37).
- To St. Ephraem she was as innocent as Eve before her fall, a virgin most estranged from every stain of sin, more holy than the Seraphim, the sealed fountain of the Holy Ghost, the pure seed of God, ever in body and in mind intact and immaculate ("Carmina Nisibena").
- Jacob of Sarug says that "the very fact that God has elected her proves that none was ever holier than Mary; if any stain had disfigured her soul, if any other virgin had been purer and holier, God would have selected her and rejected Mary". It seems, however, that Jacob of Sarug, if he had any clear idea of the doctrine of sin, held that Mary was perfectly pure from original sin ("the sentence against Adam and Eve") at the Annunciation.
St. John Damascene (Or. i Nativ. Deip., n. 2) esteems the supernatural influence of God at the generation of Mary to be so comprehensive that he extends it also to her parents.
