Presentation Transcript

  1. FUNDOSCOPY IN PIH RETINA • Mirror to the cardiovascular system of the body FUNDOSCOPY • Visualization of hypertensive changes PIH • Retinal changes run parallel with the severity of hypertension hence that of pre-eclampsia.

  2. PROCEDURE ONE DROP EVERY 10 MINUTES THREE TIMES FUNDOSCOPY AFTER ONE HOUR BEFORE FOUR HOURS

  3. SYSTEMIC HYPERTENSION • VASOSPASM • VASOSCLEROSIS • RETINOPATHY

  4. NORMAL FUNDUS • Uniform Caliber • Smooth sinuous course • Brach at obtuse angle

  5. VASOSPASM • NARROWING • STRAIGHTENING • ACUTE ANGLED BRANCHING • A-V RATIO 1:3

  6. VASOSCLEROSIS SALU’S SIGN Deflection in the course of the vein at the Arterio-venous crossing

  7. VASOSCLEROSIS GUNN’S SIGN Concealment of the vein beneath the artery at the Arterio-venous crossing

  8. RETINOPATHY • SOFT EXUDATES • RETINAL HEMORRHAGES • RETINAL EDEMA • HARD EXUDATES • RETINAL DETACHMENT

  9. RETINOPATHY SOFT EXUDATES • Occulsion of precapillry arteriole • Capillary nonperfusion • Localised axoplasmic stasis • Compact yellowish white fluffy lesions • Cotton wool spots

  10. RETINOPATHY FLAME SHAPED HAEMORRGHAGES • Fibrinoid necrosis in the vessel wall • Located in the Nerve fibre layer of retina • Bright red flamed shaped hemorrhage

  11. RETINOPATHY MACULAR STAR • Increased capillary Permeability • Retinal edema • Precipitation of lipids • Discrete dense yellow lesions • Macular star HARD EXUDATES

  12. RETINAL DETACHMENT LOCALISED RETINAL DETACHMENT • Accumulation of Serous fluid between • Retinal pigment epithelium and • Neurosensory retina

  13. RETINAL DETACHMENT TOTAL BULLOUS DETACHMENT

  14. OPTIC DISC EDEMA MALIGNANT HYPERTENSIVE RETINOPATHY
