2. WHAT IS OPTIC ATROPHY
It is the condition used to describe the optic disc following degeneration of the optic nerve.

3. POA VS NORMAL

4. NORMAL VS OPTIC ATROPHY

5. TYPES OF OPTIC ATROPHY
PRIMARY OPTIC ATROPHY: When the OA is due to any disease affecting the optic nerve but there are no ophthalmoscopic evidence of previous inflammation.
SECONDARY OPTIC ATROPHY: When the OA is due to any disease affecting the optic nerve with a clear ophthalmoscopic evidence of previous insult of the optic nerve.

6. PRIMARY OPTIC ATROPHY

7. SECONDARY OPTIC ATROPHY

8. CAUSES OF OPTIC ATROPHY
PRIMARY OPTIC ATROPHY
Multiple sclerosis
Lebers disease
Compressive lesions of orbit/brain
Toxic optic neuropathy-Lead, Tobacco.
SECONDARY OPTIC ATROPHY
Papillitis/Optic neuritis
Neuroretinitis
Papilloedema

9. CLINICAL FEATURES OF OPTIC ATROPHY
Optic Disc of PRIMARY OPTIC ATROPHY- Pale & CHALKY WHITE, well defined margins and the background retina normal.
Optic Disc of SECONDARY OPTIC ATROPHY- DIRTY WHITE, ill defined margins and background retina may be affected.

10. CLINICAL FEATURES OF OA
VA: Patient is blind in the eye with OA.
PUPIL: Dilated not reacting to light, if partial and unilateral- Look for MARCUS GUNN PUPIL/RAPD.
Early or partial atrophy- Color vision- defective, Visual fields- Central scotoma

11. SPECIFIC TYPES CONSECUTIVE OPTIC ATROPHY CRAO Retinitis Pigmentosa
CAVERNOUS OPTIC ATROPHY
Glaucomatous optic atrophy

12. CONSECUTIVE OPTIC ATROPHY
RETINITIS PIGMENTOSA
CRAO

13. FOSTER-KENNEDY SYNDROME

14. INVESTIGATIONS
To find out the cause of the optic atrophy to prevent further loss in the same eye and safe guard the fellow eye.
Sometimes may show a SOL of the brain and save the patients life. RADIOLOGY- CT/MRI SCANS!!!!!
Investigations accordingly.

15. TREATMENT NO TREATMENT ONCE OPTIC ATROPHY SETS IN. BAD PROGNOSIS.
EARLY INTERVENTION AND TREATMENT OF THE CAUSE SHOULD BE ATTEMPTED.
