Purpose:

To evaluate stereoacuity in patients with schizophrenia.

Material and Method:

45 cases that had a visual acuity of 10/10 and a diagnosis of schizophrenia were included in the study; uncommunicative patients were excluded. Control group was formed of 45 healthy individuals of the same age and sex with the patients. Titmus test was performed in both groups at a distance of 16 inches (405 mm) with polarized spectacles. T-test was used for statistical evaluation.

Results:

Sex distribution of the cases was 35\10 (M\F), with a mean age of 34.7±1.0 years. Stereoacuity was 46.2±1.1 arc sec in the patient group, while it was 41.5±0.5 arc sec in the control group (p=0.001). The mean stereoacuity of the patients with visual hallucinations was 52.7±1.9, while it was 44.5±2.0 (p=0.02) in the patients who had no visual hallucination. There was no statistically significant difference between treated and untreated patients.

Discussion:

Stereoacuity was found to be decreased in patients with schizophrenia, especially who had visual hallucinations, when compared with healthy individuals of the same age.
