Human Immunodeficiency Virus (HIV) intricately targets CD4-positive T lymphocytes, compromising the immune systems resilience. While the systemic impact of HIV is well-documented, its influence extends into ocular tissues, giving rise to a diverse array of manifestations reflective of evolving immunological dynamics. This study explores the pivotal correlation between CD4 counts and ocular complications in HIV, unraveling crucial insights into the underlying pathomechanisms. Investigating the intricate interplay between the immune system and ocular health, the study illuminates the role of CD4 counts as vital indicators of susceptibility and disease progression in the realm of HIV-associated ocular manifestations. Navigating this immunological tapestry provides profound implications for diagnosis, treatment, and future research, offering avenues to refine clinical strategies and elevate the quality of care for individuals grappling with both HIV and ocular complications. Ocular lesions predominantly impact the posterior segment, encompassing conditions like HIV vasculopathy, infectious retinopathy or choroidopathy, and rare neoplasms. In developed nations, HIV vasculopathy or microangiopathy emerges as the predominant AIDS manifestation (40–60%), characterized by retinal hemorrhages, cotton-wool spots, microaneurysms, ischemic maculopathy, and telangiectatic vessels. Conversely, large vessel disease is infrequently observed. Cytomegalovirus (CMV) retinitis, constituting 15–40% of infectious retinopathy in AIDS, leads to complications like immune recovery uveitis (IRU) and retinal detachment, serving as major contributors to visual morbidity. Involvement of the anterior segment is less common, featuring complex cataract, anterior uveitis, fungal keratitis, herpes simplex and zoster keratitis, peripheral ulcerative keratitis, and bacterial keratitis
