All of the following are true of Eales disease except –
**Core Concept**
Eales disease is an idiopathic **inflammatory venous occlusive disease** that primarily affects the retinal veins, leading to retinal hemorrhages and neovascularization. It is characterized by a **trilateral association** of retinal venous occlusion, neovascularization, and vitreous hemorrhage. The disease typically affects young adults.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general aspects of Eales disease. The disease is known for its **recurrent vitreous hemorrhages** and **retinal neovascularization**, which can lead to complications such as retinal detachment. The exact pathogenesis is unknown, but it is thought to involve **immune-mediated inflammation** and **oxidative stress**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, it's challenging to provide a precise explanation. However, if option A discussed a common association or characteristic of Eales disease, it would be considered correct, making the explanation for why it's incorrect dependent on the specifics of the option.
**Option B:** Similarly, without knowing the specifics of option B, we can't determine why it might be incorrect. If it mentioned an unrelated condition or an incorrect pathophysiological process, it would be easy to identify as incorrect.
**Option C:** Again, lacking the details of option C, we can only speculate. If option C referred to an aspect of Eales disease that is not accurate or relevant, it would be straightforward to explain its incorrectness.
**Option D:** As with the other options, without the specifics, we can't provide a detailed explanation for why option D might be incorrect. If it described a feature or consequence of Eales disease inaccurately, it would be simple to point out the error.
