Diagnosis
Methods used to diagnose keratoconus
The first and most important part is to diagnose the clinical suspicion in the examination, and then perform corneal imaging that detects the diagnosis.
Typically, the patient returns to life in the first decade of his life with blurred vision (sometimes progressive), sometimes reporting photophobia, daze, monophasic double vision.
High asthmatics and scissor reflexes are common in retinoscopy. In advanced stages, the cornea is visible in the form of a cone.
The following symptoms are evident in the bulb examination:
- Fleischer line: The iron deposition of the base layer of the corneal epithelium cells, which is a pigmented ring, is the result of the accumulation of ferritin particles in the cytoplasm of the epithelial cells, which is commonly seen around the hips.
- Thin stroma at the site of the cornea and epithelium of the cornea and the anthropometric form of keratocytes
- Chinese or cortical laceration (vogts strine)
- Various degrees of corneal scarring
The reason for these changes is unknown, but the theories suggest changes in the level of enzyme and genetic predisposition. The changes in the enzyme level include increased proteinaceous activity, which leads to breakage of cornea collagen in the cornea.
The ratio of Keratan Sulfate to Dromatan sulfate is different from that of normal people.
There has also been an increase in the level of lysosomal and proteolytic enzymes in these individuals.
The next step is to recognize the use of imaging:

- Clean Ultrasound Meter: Detecting the Thinnest Cornea Place
Lab tests:
To evaluate genetic diseases associated with:
- Down Syndrome
- congenital condition laber
- Ehlers Danlos
- And other medical problems
Initial signs of keratoconus
- Non-corneal refractive error between two eyes with high astigmatism or increased astigmatism
- Corneal surface imperfections
- Retinoscopy scissor reflex
- Imaging symptoms include inferior steeping and increased keratometry and …
- Thin cornea, especially in the lower cornea
- Rizutti sign: See cone mode inside the cornea when light from the outer side of the cornea
- Fleischerring
- Vogt’s String
Delayed signs of keratoconus include:
- Munson’s Sign Upper Eyelid Slow Down Look
- Surface oscillation of cornea due to dome layer rupture
- Acute hydropathy due to rupture of the lumbar spine and the ulcerative fluid penetration in the stroma due to thickening of the cornea stroma with loss of vision and pain.
- Oscars in stroma after a hydropathic healing
Progressive keratoconus:
This development can be seen at any age. It’s harder to improve eye vision by progressing the disease.
Hard lenses can relieve these irregularities to some extent due to the pressure on the cornea.
