Relation between iridopathy and retinopathy in diabetes

Area of Science:

• Ophthalmology
• Diabetology
• Medical Imaging

Background:

• Diabetic iridopathy (DI) and diabetic retinopathy (DR) are common complications of diabetes.
• Assessing the relationship between DI and DR is crucial for patient management.
• Clear media in diabetic eyes allows for detailed ocular examination.

Purpose of the Study:

• To evaluate the relationship between diabetic iridopathy (DI) and diabetic retinopathy (DR).
• To determine the efficacy of iris fluorescein angiography in assessing DR and DI.
• To assess the utility of iris fluorescein angiography in surgical planning for diabetic patients.

Main Methods:

• Evaluated 225 eyes from 117 diabetic patients with clear media.
• Utilized iris and retinal fluorescein angiography to classify DI and DR.
• Classified DI into absence, non-proliferative, proliferative, and neovascular glaucoma.
• Classified DR into absence, background, pre-proliferative, and proliferative stages.

Main Results:

• Iris fluorescein angiography showed 44.5% sensitivity and 88% specificity for DR detection.
• In pre-proliferative and proliferative DR, iris neovascularization detection yielded 56% sensitivity and 100% specificity.
• Positive predictive value for iris neovascularization was 100% in advanced DR.

Conclusions:

• Iris fluorescein angiography provides valuable information regarding diabetic retinopathy.
• This imaging technique is beneficial for identifying patients at risk of complications.
• It aids in surgical planning for diabetic patients, particularly those with media opacities.
