Introduction: Retinal Angiomatous Proliferation (RAM), a distinct subtype of neovascular age-related macular degeneration (AMD), presents unique challenges in diagnosis and management. This article provides a thorough examination of RAM, including its pathogenesis, clinical presentation, diagnostic modalities, treatment options, and prognosis.

Pathogenesis: RAM is characterized by the development of abnormal blood vessels originating from the retinal circulation, which penetrate the Bruch’s membrane and extend into the subretinal or intraretinal space. The exact etiology of RAM remains unclear, but it is believed to involve complex interactions between genetic predisposition, environmental factors, and inflammatory mediators.

Clinical Presentation: Patients with RAM typically present with gradual, progressive vision loss, often accompanied by metamorphopsia and central scotomas. Fundus examination may reveal intraretinal hemorrhages, serous retinal detachments, and intraretinal or subretinal exudates. Optical coherence tomography (OCT) imaging can provide valuable insights into the extent and location of neovascularization.

Diagnostic Modalities: Diagnosing RAM requires a combination of clinical evaluation and multimodal imaging techniques. Fluorescein angiography (FA) and indocyanine green angiography (ICGA) are essential for identifying the characteristic vascular lesions associated with RAM. Additionally, OCT angiography (OCTA) offers non-invasive visualization of retinal vasculature and may aid in the early detection of neovascular complexes.

Treatment Options: The management of RAM often involves a multidisciplinary approach, with treatment goals focused on preserving visual function and minimizing disease progression. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents, such as ranibizumab and aflibercept, have demonstrated efficacy in reducing macular edema and stabilizing or improving visual acuity. Photodynamic therapy (PDT) and focal laser photocoagulation may be considered in select cases, particularly those with persistent or recurrent neovascularization.

Prognosis: The prognosis of RAM varies depending on the extent of disease involvement, response to treatment, and presence of associated complications. Despite advancements in therapeutic options, RAM remains a challenging condition to manage, with a propensity for disease recurrence and vision-threatening complications. Long-term follow-up is essential to monitor disease activity and optimize treatment outcomes.
