Freckle on the iris, can affect pupil shape
Uveal melanoma
Primary malignant tumor, may be from previous nevus
Iris malignant melanoma
Tumor on iris, can cause irregular pupil
Ciliary body melanoma

Metastatic carcinoma
Other cancer that metastases to eye
Iris pigment epithelium cyst
Can detach, no visual impairment
Anisocoria
2 different sized pupils
Iris coloboma
Happens in pregnancy/early life, pupil doesn’t fully open
Aniridia
No iris
Vitreitis
Inflammation of vitreous causes cells and flare
Endophthalmitis

Anterior to iris, affects AC & trabecular meshwork
Intermediate uveitis

Asteroid hyalosis
Calcium & lipid deposits in vitreous
Vitreous hemorrhage
Blood in vitreous, vitreous isn’t see through to retina
Iritis
Inflammation of iris
Symptoms photophobia, redness, eye pain
Signs ciliary flush, cells & flare, Synechia
Mydriasis
Dilated pupils
Hyphema
Pool of blood in AC bc of disrupted vessels of iris/ciliary body
Pathologic myopia
High myopia, tilted disc, dome macula elongated axial eye length
Macular hole
Vitreous shrinks and pulls retina making macular hole. 4 stages, 2:1 ratio in males. can be treated with gas bubble
