Abstract :

AIM: To measure the ocular deviation less than 40 PD in children less than 5 years of age with photoscreener and compare with Krimsky and Hirschberg method. METHOD: A total of 446 children less than 5 years of age and degree of misalignment less than 40 PD were included in the study. Exclusion criteria was any misalignment above 40 PD. Measurement of ocular misalignment was done in all patients with Hirschberg method, Krimsky method and photoscreener (plusoptix A 09, GmbH, Germany). Time taken for the measurement of deviation was noted for each patient. RESULT: There was no statistical significant difference between measurement of Krimsky and Plusoptix however both showed significant difference with the Hirschberg test. Time taken for measurement of ocular deviation with paediatric autorefractometer was comparable to Hirschberg test but significantly less as compared to time taken with Krimsky test as child cooperation is very important while measuring deviation. CONCLUSION: Photoscreener is an effective tool for measurement of deviation below 40 PD and gives results comparable to Krimsky test. Since time required for measurement of deviation with photoscreener is much less as compared to Krimsky and requires less child cooperation hence it can be recommended for measurement of deviation less than 40 PD.
