The efficacy and safety of reducing intraocular pressure to single‐digit levels in Normal‐tension glaucoma: A systematic review and meta‐analysis

Achieving single-digit IOP levels is associated with a significant reduction in visual field progression rates. However, the balance between efficacy and safety must be considered, as aggressive IOP reduction is also associated with a higher risk of hypotony-related complications. Postoperative hypotony was relatively frequent but generally transient and did not appear to have a significant impact on long-term visual acuity.
