Detailed Description

This clinical trial aims to address the scarcity of retinal image datasets in Pakistan by providing a comprehensive digital fundus photograph dataset, accompanied by expert grading. The dataset will encompass retinal images from Pakistani individuals, meticulously labeled by three Vitreo Retinal Specialists. These specialists will assess the presence and severity of common retinal disorders, including No Diabetic Retinopathy (No DR), Mild, Moderate, Severe, Proliferative Diabetic Retinopathy, Clinically Significant Macular Edema (CSME), and Advance diabetic Eye Diseases (ADED). Each image will also be evaluated for diagnostic clarity and the presence of any additional findings. Final grading decisions will be reached through unanimous consensus among the graders, ensuring the dataset's reliability and accuracy. This initiative holds promise for advancing ophthalmic research and improving patient care in Pakistan and beyond.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Finding inter-rater agreement among the graders
Time Frame: Two Years
The intraclass correlation coefficient will be calculated using the collected dataset to assess the consistency in grading among all graders.
Two Years
Grading Diabetic Retinopathy Severity according to International Clinical Diabetic Retinopathy Severity Scale
Time Frame: 1 Visit (1 day)

Each Fundus photograph will be evaluated according to the Severity of Diabetic Retinopathy following International Clinical Diabetic Retinopathy Severity Scale (ICDRSS). Following Diabetic Retinopathy symptoms will be graded according to this scale.

  1. No DR
  2. Mild
  3. Moderate
  4. Severe
  5. Proliferative
1 Visit (1 day)
Grading Diabetic Retinopathy Severity according to Early Treatment of Diabetic Retinopathy Scale
Time Frame: 1 Visit (1 day)

Each Fundus photograph will be evaluated according to the Severity of Diabetic Retinopathy following Early Treatment of Diabetic Retinopathy Scale (ETDRS). Following Diabetic Retinopathy symptoms will be graded according to this scale.

  1. Clinically Significant Macular Edema
  2. Advance Diabetic Eye Disease
