Summary
Age-related macular degeneration (AMD) and diabetic retinopathy (DR) alter ocular surface temperature (OST). AMD eyes showed higher OST, while DR eyes had the lowest OST, indicating systemic involvement in these conditions.
Area of Science:
- Ophthalmology
- Medical Imaging
- Thermography
Background:
- Age-related macular degeneration (AMD) and diabetic retinopathy (DR) are leading causes of vision loss.
- Understanding their impact on ocular physiology is crucial for early detection and management.
Purpose of the Study:
- To investigate the effect of AMD and DR on the ocular thermographic profile.
- To compare ocular surface temperature (OST) in patients with AMD and DR versus healthy controls.
Main Methods:
- Retrospective cross-sectional study of 133 patients with DR or AMD and 48 controls.
- Ocular surface temperature (OST) was measured using a thermal imaging camera.
- Mean temperatures of the medial cantus, lateral cantus, and cornea were analyzed.
Main Results:
- Ocular surface temperature (OST) was significantly higher in AMD patients and lowest in DR patients (P < 0.001).
- Eyes with diabetic macular edema exhibited higher OSTs, comparable to the AMD group.
- No significant OST difference was found between neovascular and nonneovascular AMD.
Conclusions:
- AMD and DR, though posterior segment diseases, impact overall ocular surface temperature (OST).
- Differences in OST between AMD and DR may reflect distinct pathophysiological processes.
- Further research is needed to elucidate the role of vasculature, circulation, and metabolism in ocular temperature regulation for these conditions.
