OCT-Based Screening for Early Retinal Changes in Asymptomatic Diabetic Patients

Source: ClinicalTrials.gov · Last updated 18 Nov 2025

Brief summary (registry, in English)

The goal of this observational study is to detect early retinal changes in people with diabetes who do not have visual symptoms. The study will use Optical Coherence Tomography (OCT) and fundus examination to screen for early retinal involvement in diabetic patients. The main questions this study aims to answer are: Can OCT detect early retinal changes before symptoms appear in people with diabetes? Is fundus examination useful for identifying early diabetic retinal changes? Participants will undergo a comprehensive eye examination, including OCT macular scans and fundus examination, at Assiut Ophthalmology Hospital. No treatment or invasive procedures will be performed as part of this study. The collected data will help improve early detection and prevention of diabetic retinal complications.

Age

  • Presence of other retinal diseases (e.g., age-related macular degeneration, retinal vein occlusion)

Other

  • Media opacity that prevents adequate OCT imaging (e.g., dense cataract, corneal opacity)
  • Uncooperative participants or those who decline to give consent
