Objective:
The debate pertaining to the association between Keratoconus (KC) and Mitral Valve Prolapse (MVP) continues to occur among physicians. The results of cross-sectional studies attempting to present the co-existing prevalence of these two diseases remain indeterminate. We compiled the first meta-analysis to determine the pattern of prevalence between the two diseases.
Methods:
Two separate literature searches for cross-sectional studies were performed for this metaanalysis. The first search encompassed finding literature comparing the prevalence of KC between patients with MVP and a control group. The second search pertained to finding studies comparing the prevalence of MVP patients with KC and a control group.
Results:
Six studies reported the prevalence of MVP in patients with KC and a control group. The prevalence was 41.6% in patients with KC and 11.5% in patients without KC (OR = 7.06 [95% CI = 2.41-20.64]). There was a significant heterogeneity among the studies (I2 = 84%). Two studies showed the prevalence of KC in patients with MVP and a control group. The prevalence was 17.0% in patients with KC and 2.9% in the control group (OR = 5.07 [95% CI = 1.08-23.83]). There was no heterogeneity within the analysis (I2 = 0%).
Conclusion:
There is a statistically significant co-existing prevalence between MVP and KC. Patients with KC are more likely to present with MVP, and patients with MVP are more likely to present with KC.
Insights
This meta-analysis found a significant association between Keratoconus (KC) and Mitral Valve Prolapse (MVP). Patients with KC are more likely to have MVP, and vice versa, indicating a co-existing prevalence.
Area of Science:
- Ophthalmology
- Cardiology
- Medical Genetics
Background:
- The association between Keratoconus (KC) and Mitral Valve Prolapse (MVP) is debated.
- Previous cross-sectional studies have yielded indeterminate results regarding their co-existing prevalence.
Conclusions:
- There is a statistically significant co-existing prevalence between MVP and KC.
- Patients with KC have a higher likelihood of presenting with MVP.
- Patients with MVP have a higher likelihood of presenting with KC.
