Herbert Weir Smyth, A Greek Grammar for Colleges

μείζω γιγνόμενον τὸν ἄνθρωπον περιορῶμεν we allow the man to grow greater (we look with indifference on his growing power) D. 9.29, ““οὐ περιεῖδον ἐμαυτὸν ἄδοξον γενόμενον” I did not suffer myself to become obscure” I. 12.11, ““ἔτλησαν ἐπιδεῖν . . . ἐρήμην μὲν τὴν πόλιν γενομένην, τὴν δὲ χώρα_ν πορθουμένην” they had the courage to look calmly on their city made desolate and their country being ravaged” I. 4.96. So even with the uncompounded ὁρῶ in poetry. (With the infinitive περιορῶ no longer connotes perception and simply equals ἐῶ allow.)
