Flashcard 11: Cataracts often result in glare and _____ vision, especially at night

Answer: decreased

Flashcard 12: _____ sign is the hemorrhage caused by cataract surgery in Fuchs heterochromic iridocyclitis.

Answer: Amsler

Flashcard 13: Loss of ability to see objects in bright sunlight, blinded by the light of oncoming headlamps when driving at night is seen with _____ cataract or posterior subcapsular cataract

Answer: nuclear

Flashcard 14: A _____ and irregular anterior chamber is seen in anterior uveitis due to formation of posterior synechiae

Answer: shallow

Flashcard 15: Cortical cataract can be of _____ type (70% cases), where radial spoke-like pattern start in the periphery and extending centrally, and lead to late visual loss

Answer: cuneiform

Flashcard 16: Iridocyclitis is associated with _____ cataract, which is characterized by a breadcrumb appearance and polychromatic lustre.

Answer: complicated

Extra: Complicated cataract is a sequela of chronic iridocyclitis. Key features include: 1. **Polychromatic lustre**: A rainbow-like play of colors seen at the posterior pole. 2. **Breadcrumb appearance**: Small opacities seen within the lens.

Flashcard 17: _____ cataract may arise either due to delayed development of anterior chamber or due to corneal perforation

Answer: Anterior polar

Flashcard 18: Modifiable risk factors for cataracts include _____ and excessive alcohol use

Answer: smoking

Flashcard 19: Monocular diplopia or polyopia is seen with _____ cataract (incipient stage)

Answer: cortical

Flashcard 20: Are posterior synechiae typically seen in Fuchs' heterochromic iridocyclitis?

Answer: No

Extra: Fuchs' heterochromic iridocyclitis (FHI) is characterized by a triad of heterochromia iridis, cataract (typically posterior subcapsular), and glaucoma. A key diagnostic feature of FHI is the **absence of posterior synechiae**, which helps distinguish it from other forms of chronic anterior uveitis. This makes it a unique cause of complicated cataract.
