11. Fundus photography of a 40-year-old male with positive Mantoux test with choroidal tuberculoma.

12. Acute central retinal artery occlusion in Adamantiades-Behçet disease Fundus photography and fluorescein angiography. Note grossly impaired perfusion, retinal whitening and relative cilioretinal sparing.

14. Sturge-Weber Syndrome: Choroidal Hemangioma Nevus flammeus (Port Wine Stain )

15.  Benign ocular conditions Amiodarone – whorl keratopathy  Toxic Retinopathies Thioridazine, chloroquine, hydroxychloroquine, tamoxifen  Toxic Optic Neuropathies Ethambutol, isoniazid

16. DRUGS CAUSING RETINAL TOXICITY  DIGITALIS – ABNORMAL COLOUR VISION  ETHOMBUTOL,QUININE- OPTIC-NEUROPATHY  CHLOROQUINE – BULLS EYE MACULOPATHY RETINAL DEGENERATION  PHENOTHIAZINE – PIGMENTARY RETINOPATHY AND RETINAL EDEMA  TAMOXIFEN – PIGMENTARY RETINOPATHY

17.  Caused by the Drugs Chloroquine or hydroxychloroquine,  Used for rheumatoid arthritis, SLE, etc  This eye toxicity limits long-term use of the drugs.  Drug bind to melanin pigment in the RPE, and this may serve to concentrate the drugs or to prolong their adverse effects.

18.  Salt and Pepper Fundus is found in Congenital syphilis, choroideremia, Leber's congenital amaurosis, rubeola, poliomyelitis, cmv retinitis.  combination of RPE loss and migration produces the "salt and pepper" fundus. The pepper may be clumpy ("bone spicular"),  Damaged RPE migrate into superficial retina. The black pigment flecks are particularly evident in the retinal mid-periphery.

19.  A Myopic Crescent is white or grayish white moon- shaped atrophic changes of choroid develop at the temporal border of disc of myopic eyes.  In myopia that is no longer progressing, the crescent may be asymptomatic except for its presence on ocular examination. However, in high- degree myopia, it may extend to the upper and lower borders, or form a complete ring around the optic disc and form a central scotoma.myopiaoptic disccentral scotoma
