Prevalence and characteristics of oblique astigmatism.

ABSTRACT:

Objective

To examine the incidence and characteristics of eyes with oblique astigmatism stratified by meridian, age, sex, and eye side (left to right).

Methods

One thousand eyes of 1000 patients with oblique corneal astigmatism underwent videokeratographic examination and was classified into 4 meridian categories: (1) 31°-45°, (2) 46°-59°, (3) 121°-135°, and (4) 136°-149°. Amounts of regular and irregular astigmatism, and the vertical/horizontal (Rx) and oblique astigmatism components (Ry) decomposed using vector analysis were compared among the 4 categories and age groups, and between sexes and eye sides.

Results

Incidences of the 4 meridian categories were similar and did not differ significantly among age groups or between sexes. The incidence was significantly gre
