In which of the following uveitic conditions is it contraindicated to put intraocular lens after cataract extraction
**Core Concept**
The question requires understanding of uveitic conditions and their implications for intraocular lens (IOL) implantation after cataract extraction. Specifically, it involves recognizing the risks associated with IOL implantation in patients with certain types of uveitis.
**Why the Correct Answer is Right**
Juvenile rheumatoid arthritis (JRA) is a form of chronic uveitis that can lead to severe complications, including cataract formation and vision loss. In patients with JRA-associated uveitis, the inflammation can persist even after cataract surgery, increasing the risk of complications such as posterior synechiae, secondary glaucoma, and phthisis bulbi. Implanting an IOL in such cases can exacerbate the inflammation and lead to vision loss or other complications. The use of IOLs is generally contraindicated in patients with active or chronic JRA-associated uveitis.
**Why Each Wrong Option is Incorrect**
**Option A:** Fuchs heterochromic cyclitis is a form of chronic uveitis that can be managed with IOL implantation, as the inflammation is typically mild and controlled.
**Option C:** Psoriatic arthritis is a systemic inflammatory condition that can involve the eyes, but it is not typically associated with the same level of ocular inflammation as JRA, making IOL implantation a safer option.
**Option D:** Reiter's syndrome is a form of reactive arthritis that can involve the eyes, but it is generally not as severe as JRA-associated uveitis, and IOL implantation may be possible with proper management.
**Clinical Pearl / High-Yield Fact**
It is essential to carefully evaluate patients with uveitic conditions before considering IOL implantation after cataract extraction. A thorough understanding of the underlying disease process, including the presence and severity of inflammation, is crucial in making an informed decision.
**✓ Correct Answer: B. Juvenile rheumatoid arthritis**
