Q: The most common ocular lesion peculiar to HIV infection in early stage is :

Soft exudates in retina. ***Soft exudates in retina*** - **Soft exudates**, also known as **cotton wool spots**, are the most common early ocular manifestation in HIV infection. - They represent ischemia of the nerve fiber layer due to microvascular occlusion and do not generally affect vision significantly. *Retinal necroses* - **Retinal necroses**, such as those seen in **progressive outer retinal necrosis (PORN)** or **acute retinal necrosis (ARN)**, are typically severe and rapidly progressive. - They are usually associated with advanced HIV infection (low CD4 count) and viral etiologies like **CMV retinitis** or **VZV**, not early stage HIV. *Retinal hemorrhages* - **Retinal hemorrhages** can occur in HIV, but they are often associated with systemic conditions like **thrombocytopenia** or **anemia**, or advanced opportunistic infections. - They are not considered the *most common* lesion peculiar to early HIV itself. *Kaposi's sarcoma* - **Kaposi's sarcoma** is a vascular tumor caused by **HHV-8 infection** and is associated with advanced immunosuppression in HIV. - While it can affect the conjunctiva or eyelids, primary intraocular involvement is rare and typically presents in later stages, not early HIV.
