About this trial
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.
Eligibility criteria
Qualifiers
Confirmed diagnosis of type 1 or type 2 diabetes mellitus for at least 6 months
Best-corrected visual acuity (BCVA) of 6/6 using Snellen chart
No visual symptoms (no blurred vision or metamorphopsia)
Clear ocular media allowing high-quality OCT imaging
Disqualifiers
History of previous macular disease or treatment (laser photocoagulation or intravitreal injection)
Media opacity that prevents adequate OCT imaging (e.g., dense cataract, corneal opacity)
Presence of other retinal diseases (e.g., age-related macular degeneration, retinal vein occlusion)
Systemic or neurological diseases that affect the retina or visual pathway
