The use of benzalkonium chloride in topical glaucoma treatment: An investigation of the efficacy and safety of benzalkonium chloride-preserved intraocular pressure-lowering eye drops and their effect on conjunctival goblet cells.
Glaucoma is a leading cause of the global prevalence of irreversible blindness. The pathogenesis of glaucoma is not entirely known, but the major risk factors include advancing age, genetic predisposition, and increased intraocular pressure (IOP). The only evidence-based treatment is a lowering of IOP through the use of eye drops, laser procedures, or surgical interventions. Although laser treatment is gaining recognition as a first-choice treatment option, the most common approach for managing glaucoma is IOP-lowering eye drops. A major challenge in the treatment is the occurrence of adverse events and poor adherence. In this context, the ocular surface is an area of great concern, as most glaucoma patients have dry eye disease (DED), which is largely caused by eye drops. Preservation with benzalkonium chloride (BAK) is a controversial topic due to its potential role as a significant cause of DED. A systematic review and meta-analyses investigate potential differences in efficacy and safety between BAK-preserved and BAK-free anti-glaucomatous eye drops (I). Many of the included studies report on ocular surface damage caused by the application of BAK-preserved eye drops. However, the meta-analyses addressing hyperemia, number of ocular adverse events, and tear break-up time did not identify any significant differences. The latter is likely due to varying measurement methods, different endpoints, and study durations. It is, therefore, possible that the large variations between the studies conceal differences in the safety profiles. The efficacy meta-analysis finds that there are no differences in the IOP-lowering effect between BAK-preserved and BAK-free eye drops, indicating that BAK is not necessary for the effectiveness of eye drops. To promote more homogeneous choices of endpoints and methods when evaluating BAK-preserved and BAK-free glaucoma treatments, a Delphi consensus statement was performed. In this study, glaucoma experts and ocular surface disease experts reached consensus on the key factors to consider when designing such studies (II). The hope is to have more studies with comparable endpoints that can systematically show the potentially adverse effects of BAK. The preclinical studies in the current Ph.D. research focus on conjunctival goblet cells (GCs). GCs are important for the ocular surface because they release the mucin MUC5AC, which is an essential component of the inner layer of the tear film. BAK preservation may damage the GCs and r. Danish Summary: Glaukom (grøn staer) er en af de hyppigste årsager til blindhed på verdensplan. Årsagen til glaukom kendes ikke, men de vaesentligste risikofaktorer er alder, genetik og forhøjet intraokulaert tryk. Den eneste evidensbaserede behandling er saenkning af øjentrykket med enten øjendråber, laser eller kirurgi. Omend laserbehandling er blevet tiltagende anerkendt som førstevalgsbehandling, er øjendråber den mest udbredte behandlingsform. Da øjendråber mod glaukom kan medføre vaesentlige bivirkninger, er det en stor udfordring, at patienter med glaukom ikke bruger deres øjendråber korrekt. I denne sammenhaeng er øjenoverfladen et område, der vaekker bekymring, da langt de fleste glaukompatienter lider af øjenoverfladesygdom, som overvejende skyldes øjendråbebehandling. Konservering med benzalkoniumklorid (BAK) er kontroversiel, da BAK menes at vaere en vaesentlig årsag til øjenoverfladesygdom. Et systematisk review og metaanalyser undersøger forskelle i effekt og bivirkningsprofil mellem BAK-konserverede og BAK-frie øjendråber (I). Flere studier rapporterer om skade på øjets overflade ved brug af BAK-konserverede øjendråber. Dog findes der ikke forskelle i metaanalyserne, der undersøger hyperaemi, antal lokale bivirkninger og tåreopbrydningstid. De inkluderede studier har meget varierende outcomes, varighed og målemetoder. Det er derfor muligt, at de store variationer studierne imellem maskerer BAK's egentlige toksiske effekt. I metaanalysen, der undersøger dråbernes tryksaenkende effekt, findes der ingen forskel mellem BAK-konserverede og BAK-frie øjendråber, hvilket indikerer, at BAK ikke er nødvendig for dråbernes tryksaenkende effekt. For at bane vejen for mere ensartede valg af end points og metoder i kliniske forsøg, der undersøger BAK-konserverede og BAK-frie antiglaukomatøse øjendråber, er der lavet et Delphi konsensus studie (II). I studiet er eksperter i glaukom og overfladesygdom blevet enige om de vigtigste elementer, der bør inkluderes, når sådanne kliniske studier designes. Håbet er at øge maengden af studier med sammenlignelige end points og metoder som systematisk kan vise BAK's potentielt uhensigtsmaessige effekt på øjendråbers bivirkningsprofil. De praekliniske studier i den foreliggende afhandling fokuserer på de konjunktivale baegerceller, da baegercellerne er vigtige for øjets overflade. Baegerceller frigiver mucinet MUC5AC, som er en vigtig bestanddel i tårefilmens inderste lag.
