Abstract

STUDY DESIGN : cross sectional study
PURPOSE : To compare the sensitivity of ocular ultrasonography and SD-OCT parameters to distinguish Grade I, II papilledema from pseudopapilledema
METHODS :The duration of the study will be from September 2022- September 2023. The study evaluates the role of ocular ultrasonography and Spectral Domain Ocular Coherence Tomography (SD-OCT) to differentiate between papilledema and pseudopapilledema. 60 patients were taken where 30 of each were taken . For B scan parameters (ONSD and 30 ⁰ test ,optic disc elevation and crescent sign ) and SDOCT parameters (p RNFL, BMO, ONHV , GCL-IPL) were taken.
RESULTS : Compared to pseudopapilledema, papilledema eyes showed larger mean ONSD , greater change(%) of ONSD at lateral gaze . In SDOCT parameters pRNFL and GCIPL had correlation with papilledema .
CONCLUSIONS : Ocular ultrasonography and SDOCT can be used to differentiate between papilledema and pseudopapilledema
