Case from
Topiramate-Induced Angle Closure: 29-year-old woman presented with bilateral blurry vision and headache. Several hours prior to presentation, she noted a progressive decrease in distance vision that limited her ability to read the whiteboard across the room.


Iridoschisis case from

Iridoschisis: This patient was seen at age 72 for the iris changes seen in this video. He was found to have narrow angles in the right eye and on slit lamp examination the right iris appeared to be split with a forward bowing of the anterior lamellae. The left iris was disintegrated inferiorly. The patient also had marked nuclear sclerotic cataract. His intraocular pressures were normal.


Posterior polymorphous corneal dystrophy (PPMD) cases from

Posterior Polymorphous Corneal Dystrophy: This patient at age 42 was diagnosed with glaucoma. At age 60 she was found to have narrow angles and underwent laser iridotomies. Two years later one of her physicians performed laser trabeculoplasty on her (ill advised). When we first saw her she had extensive angle closure with corneal endothelial changes including vesicles. She was diagnosed as having posterior polymorphous corneal dystrophy.

Posterior Polymorphous Corneal Dystrophy (Slit Lamp Only): A 44-year-old woman diagnosed with posterior polymorphous corneal dystrophy as a child. She is from a large family of individuals with PPMD.


Ciliary Body swelling case from

Ciliary Body Swelling: This patient presented in narrow angles after an ischemic central retinal vein occlusion. One can see that the iridocorneal angle is quite narrow. This is not from papillary block but from swelling of the ciliary body.
