  2. Corneal cross-linking - Wikipedia

    en.wikipedia.org/wiki/Corneal_cross-linking

    Corneal cross-linking (CXL) with riboflavin (vitamin B 2) and UV-A light is a surgical treatment for corneal ectasia such as keratoconus, [2] PMD, and post-LASIK ectasia. It is used in an attempt to make the cornea stronger. According to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [3]

  3. Keratoconus - Wikipedia

    en.wikipedia.org/wiki/Keratoconus

    In 2016, however, the FDA approved cross-linking surgery as a treatment for keratoconus and recommended that a registry system should be set-up to evaluate the long-term treatment effect. [ 10 ] [ 71 ] The Save Sight Keratoconus Registry is an international database of keratoconus patients that is tracking outcomes of cross-linking in patients ...

  4. Corneal ectatic disorders - Wikipedia

    en.wikipedia.org/wiki/Corneal_ectatic_disorders

    Keratoconus, a progressive, noninflammatory, bilateral, asymmetric disease, characterized by paraxial stromal thinning and weakening that leads to corneal surface distortion. [ 2 ] Keratoglobus , a rare noninflammatory corneal thinning disorder, characterised by generalised thinning and globular protrusion of the cornea.

  5. Pellucid marginal degeneration - Wikipedia

    en.wikipedia.org/wiki/Pellucid_marginal_degeneration

    Pain is not typically present in pellucid marginal degeneration, and aside from vision loss, no symptoms accompany the condition. However, in rare cases, PMD may present with sudden onset vision loss and excruciating eye pain, which occurs if the thinning of the cornea leads to perforation . [ 1 ]

  6. Corneal topography - Wikipedia

    en.wikipedia.org/wiki/Corneal_topography

    It is, in fact, one of the exams the patients have to undergo prior to the Cross-linking and the Mini Asymmetric Radial Keratotomy (M.A.R.K.). For example, the KISA% index (keratometry, I-S, skew percentage, astigmatism) is used to arrive at a diagnosis of keratoconus , to screen the suspect keratoconic patients and analyse the degree of ...

  7. Ehlers–Danlos syndrome - Wikipedia

    en.wikipedia.org/wiki/Ehlers–Danlos_syndrome

    Brittle-cornea syndrome is characterized by the progressive thinning of the cornea, early-onset progressive keratoglobus or keratoconus, nearsightedness, hearing loss, and blue sclerae. [5] [36] Classic symptoms, such as hypermobile joints and hyperelastic skin, are also seen often. [37] It has two types. Type 1 occurs due to variations in the ...

  8. Corneal hydrops - Wikipedia

    en.wikipedia.org/wiki/Corneal_hydrops

    Corneal hydrops is an uncommon complication seen in people with advanced keratoconus or other corneal ectatic disorders, [1] and is characterized by stromal edema due to leakage of aqueous humor through a tear in Descemet's membrane. [2]

  9. Post-LASIK ectasia - Wikipedia

    en.wikipedia.org/wiki/Post-LASIK_ectasia

    Before corneal refractive surgery such as LASIK, SMILE, and PRK, people must be examined for possible risk factors such as keratoconus. [3]Abnormal corneal topography compromises of keratoconus, pellucid marginal degeneration, or forme fruste keratoconus with an I-S value of 1.4 or more [4] is the most significant risk factor.
