Proptosis 3
- 2. GLOSSARY • INTRODUCTION • TYPES • DIFFERENTIAL DIAGNOSIS • INVESTIGATIONS
- 3. CASE SUMMARY
- 6. Introduction • Proptosis : forward protrusion of the eyeball. ( passive process) clasically seen in retro- orbital space occupying lesion. • Exopthalmos: forward protrusion of eyeball (active/dynamic process) seen in endocrinological disorders. • Pseudoproptosis:this is a clinical appearance of proptosis where dere is no forward displacement of the globe.
- 7. PROPTOMETRY It is the measurement of the distance between apex of the cornea and the bony point usually taken as deepest portion of the lateral orbital rim with the eye looking in primary gaze.
- 8. Measurements • Proptosis > 21 mm • Enophthalmos < 10–12 mm
- 9. MEASUREMENT • ABSOLUTE MEASUREMENT relating the corneal apex to a bony point on the skull. • RELATIVE MEASUREMENT comparing the position of one cornea with the other.
- 10. CLASSIFICATION LATERALITY TYPE DURATION NATURE UNILATERAL & BILATERAL AXIAL OR ECCENTRIC ACUTE ,CHRONIC & INTERMITTENT PULSATILE OR NON PULSATILE
- 11. AXIAL PROPTOSIS • Axial proptosis is caused by any space occupying lesion in the muscle cone or any diffuse orbital inflammatory or neoplastic lesions.
- 12. ECCENTRIC PROPTOSIS • Proptosis caused by any extraconal lesion or fracture displacement of orbital bones protruding inwardly.
- 13. NON AXIAL PROPTOSIS Downward:Fibrous dysplasia Fibrous mucocele Lymphoma Neuroblastoma Neurofibroma Schwannoma Subperiosteal hematoma Upward: Tumors of floor of orbit Maxillary tumors Lymphoma Lacrimal sac tumors Down & in: Lacrimal gland tumors Sphenoid wing meningoma lateral:Ethmoidal mucocele, Frontal mucocele, Lacrimal sac tumors

- 21. MEASUREMENT OF PROPTOSIS This instrument consists of a horizontal calibrated bar with movable carriers at each side. Each carrier consists of mirrors inclined at 45 degrees to reflect both the scale reading and the apex of the cornea in profile. Notches on the side carriers are placed on the bony lateral orbital margins of the patient. The patient is then asked to fixated on a point on the examiner's forehead. The apex of the cornea of each eye is superimposed on the millimeter scale reading by the inclined mirrors. The measurement of each eye is recorded by the examiner, alternately viewing with the right and left eye.
- 22. HILAL & TROCAR METHOD • A perpendicular from each corneal apex to this line is dropped, and measured to scale. If each line is greater than 21 mm, or if there is an asymmetry of >2 mm between the two, it indicates abnormality.
