Our aim was to determine the benefit of pre-operative SS-OCT to detect occult retinal pathologies in patients with advanced diabetic eye disease (ADED).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fundus photos and SS-OCT were performed pre-operatively in all patients scheduled for vitrectomy for ADED. These were reviewed by two retina specialists. A modified BIO-score based on the Nussenblatt scale of vitreous haze was used to evaluate fundus clarity on fundus photos. Findings on fundus photos were compared with the findings on SS-OCT. Any disagreement between the retina specialists was resolved upon discussion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We included 38 consecutive eyes of 35 patients. Various degrees of cataract was present in 22 eyes. In our sample, 84.2% of cases had a BIO score of 3 or more and 31.6% had a BIO score of 4 or 5. The most common diagnosis on fundus photos was vitreous haemorrhage (n = 23). Tractional retinal detachment (n = 20) was the most common diagnosis on SS-OCT. Only 3 cases had no view on SS-OCT. There was almost perfect (\u03ba = 0.933, 95% CI: 0.887-0.979), substantial (\u03ba = 0.734, 95% CI: 0.632-0.836) and moderate (\u03ba = 0.593, 95% CI: 0.494-0.692) intergrader agreement for fundus photo diagnosis, SS-OCT diagnosis and BIO scores respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SS-OCT showed potential as an adjunct to clinical examinations, especially when hazy media opacities did not allow for a clear view of the fundus. However, it is important to recognise that OCT only serves as an adjunct and cannot be used as a definitive argument for assessing surgical feasibility.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fopht.2026.1688660","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T04:46:11Z","timestamp":1776055571000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Use of preoperative swept-source optical coherence tomography in vitrectomy for advanced diabetic eye disease: a pilot study"],"prefix":"10.3389","volume":"6","author":[{"given":"Arshad","family":"Mehmood","sequence":"first","affiliation":[{"name":"Shahzad Eye Hospital","place":["Karachi, Pakistan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Altamash Shahriyar","family":"Ghazanfar","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, Aga Khan University Hospital","place":["Karachi, Pakistan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
