Abstract Details

Purpose:

To study keratoconus (KC) epidemiology, clinical and topographical findings in a tertiary referral hospital in Valladolid (Spain)

Setting:

Hospital Cl�Ã�­nico Universitario de Valladolid, �Ã�rea de Salud Valladolid Este, Universidad de Valladolid, Valladolid, Spain

Methods:

Cross-sectional study of KC patients in a tertiary referral hospital with a relative catchment area of 274.000 patients was performed. Patients referred from other hospitals were excluded. Epidemiological (Age, sex, familiar history, associated diseases, contact lens (CL) wear), clinical (Best Corrected Visual Acuity (BCVA) and corneal findings) and topographical (Mean keratometry (K) reading, K maximum (max) and corneal pachymetry) data were recorded

Results:

KC was found in 362/274.000 patients [prevalence=1:757 (132/100.000)]. Mean age at initial visit was 31,9 years. Sex: male 55%-female 45%. No association with other diseases was found in 90% patients, whereas 4.8% were associated to Down�Â�´s Syndrome. 10% of patients had family history of KC. 65% of patients wore CL. Clinical findings were: mean BCVA 10/20; Fleischer ring 42%; Vogt�â�€�™s striae 45%; previous hydrops 15%; corneal neovascularization 1%; subepithelial scarring 40%. Topographical findings were: mean Kmax 52.75D (SD �Â�±7,5); mean K>47.2D 79%; central pachymetry 447�Â�µm (SD �Â�±67) and pachymetry at conus apex 417�Â�µm (SD �Â�±78)

Conclusions:

KC is not a rare disease. Subclinical KC may increase the prevalence. Clinical and topographical findings in Valladolid area are similar to other studies
