Macular Thickness and Visual Acuity in Diabetic Hypertensive Patients

Macular Thickness and Visual Acuity in Diabetic Hypertensive Patients in Sohag City

In this study, measurements of central macular thickness using optical coherence tomography along with examination of visual acuity by Snellen's chart in diabetic hypertensive patients will be done .

correlate relationship between optical coherence tomography changes and visual acuity in patients with type 2 diabetes and hypertension

Inclusion Criteria:

• Type 2 diabetic patients with hypertension .

Exclusion Criteria:

• Patients with type 1 diabetes mellitus .
• Ocular disease ( such as high myopia , glaucoma ) .
• Patients with opacities in the media ( corneal opacities , dense cataract , vitreous hemorrhage ) .
• Systemic medication (Tamoxifen , Chloroquine , Canthaxanthine ) to avoid its effect on macular thickness .
