| description | Objective
To compare objective ocular redness measured using OCULUS Keratograph 5 M before and after 0.2% brimonidine instillation in glaucoma patients under topical hypotensive treatment.
Methods
60 eyes from 60 subjects diagnosed with glaucoma or ocular hypertension under hypotensive ocular topical treatment were analyzed. Basal Ophthalmological examination was performed.
Outcome variables were OCULUS Keratograph 5 M redness scores (RS) before and after 0.2% brimonidine instillation; overall, bulbar temporal (BT), bulbar nasal (BN), limbar temporal (LT), and limbar nasal (LN); non-invasive average tear film breakup time (Nia-BUT), non-invasive first tear film breakup time (Nif-BUT) and meibography. In addition, the following clinical data were collected: intraocular pressure, type, duration, amount, and preservatives/or not of hypotensive treatment, fluorescein corneal staining score and lower tear meniscus height.
Results
All eyes were under topical medication. All redness scores were reduced after brimonidine instillation, mean RS differences were BT 0.82 ± 0.62, BN hyperemia 1.03 ± 0.55, LN hyperemia 0.84 ± 0.49, LT hyperemia 0.71 ± 0.50 and total hyperemia 0.91 ± 0.52 (all p |

Results
All eyes were under topical medication. All redness scores were reduced after brimonidine instillation, mean RS differences were BT 0.82 ± 0.62, BN hyperemia 1.03 ± 0.55, LN hyperemia 0.84 ± 0.49, LT hyperemia 0.71 ± 0.50 and total hyperemia 0.91 ± 0.52 (all p < 0.001). 30 min after brimonidine instillation mean overall RS reduction was 47.97 ± 12.39% (p < 0.001) and after 1 h there was a persistent reduction of overall RS of 45.92 ± 14.27% (p < 0.001). Hyperemia reduction was significant and comparable between preservative and preservative-free group 0.12 ± 0.14 (p > 0.392) and between patient with combination therapy and monotherapy 0.16 ± 0.14 (p > 0.258).
Conclusion
A significant reduction of conjunctival hyperemia was objectively found in glaucoma patients under topical hypotensive treatment before and after brimonidine instillation. Its fast and long-lasting effect may be useful preoperatively in glaucoma patients to reduce intraoperative bleeding and associated complications.</description><identifier>ISSN: 1120-6721</identifier><identifier>EISSN: 1724-6016</identifier><identifier>DOI: 10.1177/11206721231199122</identifier><identifier>PMID: 37661653</identifier><language>eng</language><publisher>London, England: SAGE Publications</publisher><ispartof>European journal of ophthalmology, 2024-03, Vol.34 (2), p.480-486</ispartof><rights>The Author(s) 2023</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c340t-90bfaa3a4f93ff7cd1c1839d18fc617ab4810faf30b8832628dc0532c35ab0413</citedby><cites>FETCH-LOGICAL-c340t-90bfaa3a4f93ff7cd1c1839d18fc617ab4810faf30b8832628dc0532c35ab0413</cites><orcidid>0000-0002-6182-0753 ; 0000-0001-6727-7432 ; 0000-0001-9441-0542</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://journals.sagepub.com/doi/pdf/10.1177/11206721231199122$$EPDF$$P50$$Gsage$$H</linktopdf><linktohtml>$$Uhttps://journals.sagepub.com/doi/10.1177/11206721231199122$$EHTML$$P50$$Gsage$$H</linktohtml><link.rule.ids>315,781,785,21824,27929,27930,43626,43627</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/37661653$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Montolío-Marzo, Elena</creatorcontrib><creatorcontrib>Fernández-Narros, Rodrigo</creatorcontrib><creatorcontrib>Morales-Fernández, Laura</creatorcontrib><creatorcontrib>García-Bella, Javier</creatorcontrib><creatorcontrib>Sáenz-Francés, Federico</creatorcontrib><creatorcontrib>García-Feijoo, Julián</creatorcontrib><creatorcontrib>Martínez-de-la-Casa, Jose María</creatorcontrib><title>Improvement of objective ocular redness measured with Keratograph 5M in glaucoma patients after instilling brimonidine drops</title><title>European journal of ophthalmology</title><addtitle>European Journal of Ophthalmology</addtitle><description>Objective
