ABSTRACT
PURPOSE:
To assess changes in anterior segment parameters of keratoconus eyes at different stages of the disease in a sample of the Asian population.METHODS:
Files of 32 patients (48 eyes) diagnosed as clinical keratoconus were assessed and the following parameters noted central corneal thickness (CCT), thinnest corneal thickness (TCT), location of thinnest pachymetry, anterior chamber depth (ACD) at the centre from posterior corneal surface, ACD at 1, 2 and 3mm inferior-paracentral, ACD at thinnest pachymetry, anterior chamber volume (ACV) and anterior chamber angle (ACA). For analysis, keratoconus eyes were classified into 3 subgroups according to mean keratometry readings (mild K≤47.0D, moderate 47.0RESULTS:
Each keratoconus subgroup comprised of 16 eyes. CCT, TCT, ACD at centre, ACD at 1, 2mm inferior-paracentral and ACD at thinnest pachymetry were statistically different between mild and severe keratoconus groups (P<0.05). There were also significant differences between normal with each of the moderate and severe keratoconus groups (P<0.05). Non-significant differences were found in ACV (P=0.84) and ACA (P=0.71) between all measured groups.CONCLUSION:
With the exception of ACV and ACA, parameters that include CCT, TCT, ACD at centre, thinnest pachymetry and 1, 2 mm inferior-paracentral were significantly altered with progression of keratoconus. These findings may be useful in monitoring and management of keratoconus patients.
