Peripapillary RNFL thickness (RNFLT) was measured using spectral-domain optical coherence tomography at baseline, 1 year, and 3 years following PRP.RESULTS: The mean “average RNFLT” was 89.88 ± 14.26 μm at baseline, 85.75 ± 11.36 μm at 1-year follow-up, and 83.33 ± 11.96 μm at 3-year follow-up. There was a statistically significant difference in the average RNFL thickness at baseline and 1 year and 3 years after PRP. At 1-year follow-up, superior, inferior, and nasal RNFL measurements reduced significantly from baseline (P < 0.01). The reduction in RNFL remained statistically significant for superior and inferior quadrants 3 years after PRP.CONCLUSION: PRP causes a reduction in RNFL thickness until 3 years after the procedure. Caution should be exercised while interpreting peripapillary RNFL thickness scans in patients who have undergone PRP for diabetic retinopathy.","is_dataset_classified":null,"base_score":2.70805020110221,"endowment":2.70805020110221,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"31902994","pmcid":"PMC6826597","openalex_id":"https://openalex.org/W2979891608","authors":[],"funders":[],"total_grants":0,"fwci":2.2959,"citation_percentile":0.87135431,"influential_citations":0,"citation_trend":[{"year":2020,"count":1},{"year":2021,"count":4},{"year":2022,"count":5},{"year":2024,"count":4}],"oa_status":"gold","license":"cc-by-nc-sa","oa_locations":[{"url":"https://doi.org/10.4103/ojo.ojo_39_2018","host_type":"journal"},{"url":"https://doi.org/10.4103/ojo.ojo_39_2018","host_type":"publisher"},{"url":"https://pubmed.ncbi.nlm.nih.gov/31902994","host_type":"repository"},{"url":"https://doaj.org/article/e844ea89449941c3afed80165af3b5e9","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/6826597","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC6826597","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC6826597?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Retinal Diseases and Treatments","Retinal and Macular Surgery","Retinal Imaging and Analysis"],"mesh_terms":[],"keywords":["Medicine","Nerve fiber layer","Panretinal photocoagulation","Ophthalmology","Diabetic retinopathy","Retinal","Optical coherence tomography","Prospective cohort study","Surgery","Diabetes mellitus","Proliferative Diabetic Retinopathy","Optical Coherence Tomogram"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"doi"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-09T01:44:21.788352Z","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":[]}
