Optic Disc and Retinal Structural Changes in Takayasu Arteritis: Implications for Normotensive Glaucoma

Optic nerve changes were observed in Takayasu arteritis patients under normotensive IOP conditions, particularly a significant reduction in lamina cribrosa thickness. However, no significant thinning was observed in RNFL or ganglion cell layer thickness, suggesting that these findings may reflect early or subclinical structural alterations rather than definitive glaucomatous damage. The lamina cribrosa thinning may serve as a potential biomarker of neurodegenerative effects in Takayasu arteritis, warranting long-term follow-up.
