A woman in her 80s with bilateral open-angle glaucoma developed apparent progression of existing glaucomatous field defects, despite stable disease and consistent intraocular pressure control following bilateral trabeculectomies over a decade prior. She was concurrently diagnosed with NPH and underwent VPS. Following VPS, visual fields returned to a previously stable baseline.<\/jats:p>\n                  <jats:p>Visual field fluctuations may occur concurrently with NPH, a condition affecting intracranial pressure (ICP). Here, we report visual field worsening temporally associated with NPH onset and a rare association between VPS and field improvement in the context of prior trabeculectomy. VPS may improve visual fields in post-trabeculectomy eyes by reducing ICP, thereby narrowing the translaminar pressure gradient. Unexplained visual field changes in well-controlled glaucoma should prompt consideration of pathologies affecting ICP.<\/jats:p>","DOI":"10.1136\/bcr-2026-275027","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T13:05:27Z","timestamp":1787835927000},"page":"e275027","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Reversible visual field loss in glaucoma following ventriculoperitoneal shunting for normal pressure hydrocephalus"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9134-8285","authenticated-orcid":false,"given":"Victoria","family":"Tang","sequence":"first","affiliation":[{"name":"Eye and Vision, Flinders Health and Medical Research Institute, Flinders University, Adelaide, South Australia, Australia"},{"name":"Department of Ophthalmology, Flinders Medical Centre, Bedford Park, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamie E","family":"Craig","sequence":"additional","affiliation":[{"name":"Eye and Vision, Flinders Health and Medical Research Institute, Flinders University, Adelaide, South Australia, Australia"},{"name":"Department of Ophthalmology, Flinders Medical Centre, Bedford Park, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"2026082706051731000_19.8.e275027.1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2014.3192"},{"key":"2026082706051731000_19.8.e275027.2","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/bs.pbr.2015.06.002","article-title":"Cerebrospinal fluid pressure in the pathogenesis of glaucoma","volume":"221","author":"Jonas","year":"2015","journal-title":"Prog Brain Res"},{"key":"2026082706051731000_19.8.e275027.3","doi-asserted-by":"publisher","DOI":"10.1016\/0022-510X(65)90016-X"},{"key":"2026082706051731000_19.8.e275027.4","doi-asserted-by":"crossref","first-page":"1242","DOI":"10.1038\/eye.2015.127","article-title":"Literature review and meta-analysis of translaminar pressure difference in open-angle glaucoma","volume":"29","author":"Siaudvytyte","year":"2015","journal-title":"Eye (Lond)"},{"key":"2026082706051731000_19.8.e275027.5","doi-asserted-by":"crossref","DOI":"10.1371\/journal.pone.0082284","article-title":"Trans-lamina cribrosa pressure difference and open-angle glaucoma.
