Keratoconus is a progressive condition in which the cornea gradually thins and bulges into a cone shape, causing irregular astigmatism and blurred vision. Early diagnosis with corneal topography and tomography matters, because corneal cross-linking can slow or halt progression in many patients.
Common symptoms:
Accurate diagnosis is the foundation of successful treatment. Advanced technology lets us examine layers of the eye that could not previously be seen.
Optical Coherence Tomography
Micron-level cross-sectional imaging of the retina and optic nerve. Painless and contact-free.
Fluorescein Angiography
Uses a contrast dye to assess blood flow in the retinal vessels and diagnose vascular eye disease.
Visual Field Testing
Precise visual field testing to diagnose glaucoma and optic nerve disease.
Corneal Topography
A 3D map of the corneal surface to diagnose astigmatism and keratoconus and to plan surgery.

Mr. S. Mohammadi
Age 45 · Retinal tear
