To evaluate the diagnostic yield of Humphrey visual field (HVF) 30-2 automated perimetry in differentiating neurological from non-neurological causes of visual dysfunction.
Methods:
Design: Retrospective observational record-based study. Setting: Department of Ophthalmology at a tertiary-care referral institute in Central India. Study population: All HVF tests performed between July 2023 and June 2025 were reviewed. Of 1,438 tests performed, 383 reliable HVF tests using the 30-2 program with the Swedish Interactive Threshold Algorithm (SITA) Standard or SITA Fast strategy were included. Tests with fixation losses >20%, false positive or negative responses >15%, incomplete records, or media opacities were excluded. Observation procedure: Visual field tests were categorized according to indication as neurological or non-neurological causes. Field patterns were analyzed and correlated with clinical findings and neuroimaging results. Main outcome measure: The primary outcome was diagnostic yield, defined as the proportion of HVF (30-2 program) contributing to confirmation of neurological disease.
Results:
Among 383 HVF 30-2 tests, 226 (59.0%) were performed for neurological indications. Abnormal fields were detected in 132/226 (58.4%) neurological cases compared with 42/157 (26.8%) non-neurological cases (
Conclusion:
HVF 30-2 perimetry demonstrates high diagnostic yield for neurological disorders and serves as a reliable, noninvasive functional investigation for neuro-ophthalmic evaluation.
