Purpose. To highlight a possible causal effect of eye rubbing in the etiology of keratoconus. Methods. A 43-year-old man presented to the practice of one of the authors (I.F.G.) with the complaint of gradual onset reading difficulty. History revealed the patient to have experienced constant epiphora in the right eye throughout his life as a result of punctal agenesis, which necessitated frequent wiping of this eye. Vision in the patient's right eye had been reduced for approximately 20 years… Expand
[Unilateral keratoconus associated with continual eye rubbing due to nasolacrimal obstruction--case report].
TLDR
A 17-year-old woman with constant epiphora in the left eye throughout her life as a result of ipsilateral nasolacrimal obstruction is presented, suggesting a possible causal relationship between eye rubbing and keratoconus. Expand
Keratoconus caused by eye rubbing in patients with Tourette Syndrome.
TLDR
A possible association between TS and keratoconus exists with chronic eye rubbing being the suggested mechanism and eye rubbing seems to be an important causative factor for keratconus. Expand
The Evidentiary Significance of Case Reports: Eye Rubbing and Keratoconus
  • C. McMonnies
  • Psychology, Medicine
  • Optometry and vision science : official publication of the American Academy of Optometry
  • 2008
TLDR
Depending on their presentation, some types of case report can have a significant evidence-based function in assessing causal hypotheses and, accordingly, provide a higher evidentiary ranking than generally assigned to case reports. Expand
Ocular manifestations of congenital insensitivity to pain with anhidrosis.
TLDR
Investigation of dry eye in patients with CIPA will provide unique opportunities to explore the critical roles of the autonomic sympathetic nervous system as well as the sensory nervous system in the physiology of tear production. Expand
Bilateral Keratoconus and Corneal Hydrops Associated with Eye Rubbing in a 7-year-old Girl
TLDR
Continuous mechanical trauma, such as eye rubbing, plays a significant role in the pathogenesis of keratoconus and subsequent hydrops even in childhood. Expand
Post Filtering Surgery Globe Massage-induced Keratoconus in an Eye with Iridocorneal Endothelial Syndrome: A Case Report and Literature Brief Review
TLDR
Chronic forceful frequent eye rubbing particularly with fingertips can be assumed to be the most important causative factor for KCN formation in this patient. Expand
Abnormal Rubbing and Keratectasia
TLDR
It appears reasonable to conclude that abnormal rubbing is a cause of some types of keratoconus, not because all abnormal rubbed, or only abnormal rubbing, leads to the development of some forms of ker atoconus but because abnormal rubbing may increase the likelihood of theDevelopment of some form of kerAtoconus.

Topographic Corneal Changes in Patients with Vernal Keratoconjunctivitis - A Cross Sectional Study
TLDR
Investigation of Vernal Keratoconjunctivitis patients finds evidence of astigmatism and keratoconus in VKC patients is more when compared to general population of the same age group. Expand
Eye Rubbing and Keratoconus: A Literature Review
Keratoconus is a progressive corneal ectactic condition that can lead to visual loss. Despite being the most common cause for keratoplasty in the developed world the aetiology is unknown. It isExpand

TLDR
A case is presented in which the condition has been present for more than 23 years and represents an extreme example of variable gene expression, that is, a case of true monocular keratoconus. Expand

Videokeratography of the fellow eye in unilateral keratoconus.
TLDR
The findings suggest that keratoconus is almost always bilateral, which support genetic influences in the pathogenesis of this disorder and videokeratoscope data presented might prove useful in the detection of early keratconus and refining patient selection for myopic keratorefractive procedures.

Keratoconus: Diagnosis and management
TLDR
The wider ophthalmic community shares in the treatment of keratoconus, so the general principles of contact lens fitting associated with this difficult condition are examined and the specific protocol used at the Flinders Medical Centre is presented. Expand

Aetiology of keratoconus.
TLDR
No significant psychoneurotic factor was found in the keratoconus patients compared with patients in the control group, and a classification of ker atoconus based on the dominant aetiological factors is proposed. Expand
The Case for Eye Rubbing as the Major Cause of Keratoconus
TLDR
Examples and arguments supporting eye rubbing as an etiology for keratoconus are presented and examples and arguments opposing that hypothesis are presented. Expand
Keratoconus and related noninflammatory corneal thinning disorders.
TLDR
The past and present literature on corneal thinning disorders is reviewed, practical approaches to diagnosis and management are outlined and treatment ranges from simple spectacle correction to keratoplasty. Expand
Baseline findings in the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study.
TLDR
Baseline findings suggest that keratoconus is not associated with increased risk of connective tissue disease and that most patients in the CLEK Study sample represent mild to moderate keratconus. Expand
On the Location of the Cone and the Etiology of Keratoconus
I suggest that the location of the cone in keratoconus is most often located in the paracentral inferonasal quadrant of the cornea due to the presence of the most senile epithelial cells in thisExpand
Keratoconus: age of onset and natural history.
TLDR
This work reports data from 74 keratoconus patients in need of keratoplasty, and describes how the onset of the process manifests optical signs: evolving astigmatism, failure of optical correction by spectacles, and distorted images. Expand
Keratoconus in two pairs of identical twins.
TLDR
Evidence of heredity as a factor in the etiology of keratoconus is supported, and videokeratography proved to be a valuable adjunct for the detection of early keratconus in a cornea with normal slit-lamp microscopy and photokeratoscopy results. Expand
