This is a rare presentation of trauma induced ectasia in a patient post-LASIK. It is possible that reduction in biomechanical integrity of the cornea from prior refractive surgery contributed to this presentation. [ncbi.nlm.nih.gov]

• Localized Edema

  Light microscopy showed loss of normal stromal collagen architecture and localized edema after collagenase exposure. CONCLUSIONS: A method for generating topographic features of corneal ectasia in human tissue is demonstrated. [ncbi.nlm.nih.gov]

• Corneal Edema

  Slit-lamp examination revealed marked corneal edema and stromal clefts in the central cornea along with radial surgical scars in her left eye. Pentacam imaging showed the typical pattern of a post-RK cornea with ectasia in her right eye. [ncbi.nlm.nih.gov]

  Damage to the corneal endothelium may then lead to corneal edema, resulting in haziness of the cornea and reduced vision. [vision-and-eye-health.com]

  These problems can include infection, inflammation, raised intraocular pressure, corneal haze and rarely corneal edema and decompensation. With prompt medical attention, most of these problems can usually be treated successfully. [seemaeye.com]

Diagnosis No laboratory workup is necessary. [emedicine.medscape.com]

SUMMARY: ICRS are an important component to the treatment of corneal ectasia. Knowledge of outcomes among specific groups of patients should improve treatment planning and nomograms. [ncbi.nlm.nih.gov]

Possible etiologies include the following: secondary to genetic factors, acquired corneal exposure during sleep, or possible intrinsic immunocompromise exacerbating ocular surface infections. [ncbi.nlm.nih.gov]

CXL to thin corneas Though the method still needs further refinement and longer-term studies in larger patient populations, it has shown promise in early test cases Keratoconus is a non-inflammatory progressive corneal thinning and ectasia of unknown etiology [theophthalmologist.com]

DISCUSSION Despite extensive research, the etiology of keratoconus has yet to be unraveled, even if its molecular and cellular changes have been established. [tmj.ro]

Pathophysiology The etiology of pellucid marginal degeneration has not been clearly established, but collagen abnormalities, as seen in keratoconus, have been reported. [emedicine.medscape.com]

The progressive etiological elucidation of keratoconus and other corneal ectasias will require continued research efforts by vision scientists and clinicians. Dr. [reviewofcontactlenses.com]

Abstract A recent epidemiology study revealed that prevalence of keratoconus was much higher than previously assumed. Therefore, it is no longer deemed an "orphan disease", as it has a relevant socioeconomic impact on the healthcare system. [ncbi.nlm.nih.gov]

This article will discuss the epidemiology of post-operative corneal ectasia, biomechanical mechanisms that may predispose the cornea to abnormal weakening after excimer laser surgery, particularly LASIK, risk factors and screening techniques, and ectasia [touchophthalmology.com]

Epidemiology Frequency United States Pellucid marginal degeneration is rare, and the exact incidence and prevalence are unknown. However, the incidence may be considerably underestimated, as this condition is often misdiagnosed as keratoconus. [emedicine.medscape.com]
