Papillitis Vs Papilledema

Here is a detailed table comparing
Papillitis (Optic Neuritis) and Papilledema:

Feature	Papillitis (Optic Neuritis)	Papilledema
Usually Affects	Unilateral (U/L)	Bilateral (B/L)
Onset	Sudden	Insidious/Chronic
Loss of Vision	Marked, painful	Negligible, gradual
Pain with Eye Movement	Present	Absent
Tenderness	Present at the insertion of MR & SR	Absent
Other Symptoms	Usually not seen	Headache, nausea, vomiting (↑ ICP)
Swelling (Edema) of Disc	2-3D swelling	>3D swelling, marked blind spot enlargement
Visual Field Defect	Centrocecal scotoma	Enlarged blind spot
Color Vision	Reduced (Dyschromatopsia)	Normal
Pupillary Reflex (RAPD)	Present (Positive)	Absent
Posterior Vitreous	Fine opacities present	Clear
Cause	Optic neuritis, Multiple sclerosis, infections	Increased intracranial pressure (tumor, hydrocephalus, meningitis)
Management	Steroids (IV Methylprednisolone)	Treat underlying cause (reduce ICP)
