A genuine title collision, not a naming accident
Both this discourse and SN 18.1 carry the identical Pali title, Cakkhusutta, and the identical English title in Sujato's translation — this isn't a coincidental resemblance between two different discourses but the same discourse structurally repeated under its own name.
The single change: who initiates the teaching
SN 18.1 begins with Rāhula's specific request — teach me briefly, so I can practice alone — while this discourse has the Buddha speak first, without any request preceding it; every other line, including the closing sequence, matches SN 18.1 exactly.
What this change might signal about the two vaggas
Paṭhamavagga frames its teachings as responses to Rāhula's own initiative; Dutiyavagga instead frames its opening teaching as the Buddha's own initiative, a subtle shift in framing that recurs as this vagga's distinguishing feature even as the doctrinal content itself stays unchanged.
Full restatement, not the compression used from here on
Despite repeating SN 18.1's content, this discourse is given in full rather than elided — the merged discourse immediately following it will compress the remaining nine categories far more heavily, but this opening discourse of Dutiyavagga restates its single category completely.
A deliberate full repeat before a very different compression
Reading this discourse against SN 18.1 confirms the content itself hasn't changed at all; reading it against SN 18.12-20 immediately afterward reveals how much more aggressively compressed the remaining categories will be by comparison.

The text
§1So I have heard. At one time the Buddha was staying near Sāvatthī. Then Venerable Rāhula went up to the Buddha, bowed, and sat down to one side. The Buddha said to him: “What do you think, Rāhula? Is the eye permanent or impermanent?” “Impermanent, sir.” “But if it’s impermanent, is it suffering or happiness?” “Suffering, sir.” “But if it’s impermanent, suffering, and perishable, is it fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir.” “… the ear … the nose … the tongue … the body … Is the mind permanent or impermanent?” “Impermanent, sir.” “But if it’s impermanent, is it suffering or happiness?” “Suffering, sir.” “But if it’s impermanent, suffering, and perishable, is it fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir.” “Seeing this, a learned noble disciple grows disillusioned with the eye, the ear, the nose, the tongue, the body, and the mind. Being disillusioned, desire fades away. When desire fades away they’re freed. When they’re freed, they know they’re freed. They understand: ‘Rebirth is ended, the spiritual journey has been completed, what had to be done has been done, there is nothing further for this place.’”
