A patient with HIV infection complains of rapidly progressive painless visual loss.Fundus shows exudates and haemorrhage especially along blood vessels. In this case, the treatment of choice would be-
**Core Concept**
The underlying condition described is **Cytomegalovirus (CMV) retinitis**, a common opportunistic infection in patients with **HIV/AIDS**, characterized by **retinal necrosis** and **inflammation**. This condition leads to **visual impairment** due to the destruction of the **retinal tissue**.
**Why the Correct Answer is Right**
Although the correct answer options are not provided, the standard treatment for CMV retinitis involves **antiviral medications**, such as **ganciclovir**, **valganciclovir**, **foscarnet**, or **cidofovir**, which target the **CMV virus** and reduce its replication, thereby slowing the progression of the disease.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, it's challenging to provide a detailed explanation, but any option not involving antiviral therapy would be incorrect.
**Option B:** Similarly, without specifics, any option not targeting CMV directly would be inappropriate.
**Option C:** And any option that does not address the viral cause would not be the treatment of choice.
**Option D:** The same reasoning applies, emphasizing the need for antiviral therapy.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **CMV retinitis** often requires **long-term antiviral therapy** to prevent recurrence and that **HAART (Highly Active Antiretroviral Therapy)** for HIV can also help in managing the condition by improving the patient's immune status.
**Correct Answer:** Unfortunately, without the provided answer choices, the correct answer cannot be specified.
