Material and Methods: The study included 43 patients in latanoprost  group, 32 patients in LTC group, and 39 healthy subjects in control group.  Bulbar conjunctival epithelial thickness was measured in all participants  using spectral domain optical coherence tomography (SD-OCT) with ante rior segment module. Ocular Surface Disease Index® (OSDI®) score,  Schirmer’s test with anesthesia and tear break-up time were recorded and  compared between groups. Results: Mean conjunctival epithelial thickness  was 31.27±3.85 µm in latanoprost group, 34.75±3.38 µm in LTC group and  39.20±4.85 µm in control group. Conjunctival epithelial thickness was sig nificantly lower in both latanoprost and LTC groups compared to control  group (p&lt;0.001). Mean conjunctival epithelial thickness was significantly  lower in latanoprost group than in LTC group (p=0.001). OSDI® score was  33.02±18.80, 28.92±19.79 and 4.92±7.16 in latanoprost, LTC and control  groups, respectively. OSDI® score was significantly higher in both la tanoprost and LTC groups compared to control group (p&lt;0.001). Mean tear  break-up time was significantly lower in both latanoprost and LTC groups  compared to control group (p&lt;0.001). Schirmer’s level wasn’t significantly  different between groups (p=0.640). Conclusion: Use of preservative-con taining latanoprost and LTC reduces conjunctival epithelial thickness and  impairs ocular surface discomfort by affecting tear stability. SD-OCT can be  used to assess anatomy of conjunctiva and conjunctival epithelium before  glaucoma surgery.</dc:description><dc:date>2026</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/kostu/10849</dc:identifier><dc:identifier>https://doi.org/10.5336/ophthal.2025-110563</dc:identifier><dc:identifier>1300-0365</dc:identifier><dc:language>en</dc:language><dc:relation>Türkiye Klinikleri Oftalmoloji Dergisi</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://kostu-rdlopen.rawdatalibrary.net/tr/items/kostu/10849</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
