DESIGN: A compilation and interpretation of experiences in the challenges and pitfalls of clinical trial design based on experiences documented in the peerreviewed literature over the last 40 years. METHODS: A review of the literature in the design and performance of clinical trials in DED with an interpretative and prognostic outlook. RESULTS: Published results of clinical trials in DED reveal problems in the design of clinical trials which are unique to this disease. These include a discordance between the signs and symptoms of DED, variability in disease course and short-term environmental effects on ocular surface staining. CONCLUSIONS: The development of better efficacy endpoints will be necessary to improve the outcomes of clinical trials to evaluate new pharmaceutical and surgical approaches to the management of dry eye. The most promising field is that of biomarkers which serve as surrogates for disease severity. As these markers undergo validation with clinical changes, it is likely that they will assume greater significance in future clinical trial designs.","is_dataset_classified":null,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18453776","pmcid":null,"openalex_id":"https://openalex.org/W1576735944","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.09488625,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2017,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://www.karger.com/Article/Pdf/131096","host_type":"publisher"},{"url":"https://doi.org/10.1159/000131096","host_type":"book series"},{"url":"https://pubmed.ncbi.nlm.nih.gov/18453776","host_type":"repository"}],"fields_of_study":["Ocular Surface and Contact Lens","Ocular Infections and Treatments","Connexins and lens biology"],"mesh_terms":["Clinical Trials as Topic","Diagnostic Techniques, Ophthalmological","Humans","Research Design","Ophthalmologic Surgical Procedures","Dry Eye Syndromes"],"keywords":["Clinical trial","Medicine","Disease","Clinical study design","Intensive care medicine","Medical physics","Pathology"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-26T13:13:43.434881Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
