Retinocytoma: understanding pathogenesis, diagnosis, and treatment approaches.

Retinocytoma, or retinoma, is a rare benign intraocular tumor primarily affecting the retina. It is often considered a precursor or a differentiated form of retinoblastoma, a malignant retinal tumor predominantly seen in children. Despite its non-aggressive nature and excellent prognosis, retinocytoma remains a significant area of interest due to its implications for genetic counseling, early detection, and management of ocular tumors.

Optimizing Surgical Management for Rhegmatogenous Retinal Detachment in Eyes with Active Retinoblastoma: A Safety-Driven Approach.

Intraocular surgeries are conventionally contraindicated for patients with active retinoblastoma (Rb) due to the potential risk of tumor dissemination. However, surgery is occasionally necessary to preserve vision in patients with a single eye when the eye is complicated by rhegmatogenous retinal detachment (RRD). This study aims to evaluate the outcomes of surgical repair for RRD in pediatric patients with active Rb utilizing a non-drainage scleral buckling approach.

Imaging of Uveal Melanoma-Current Standard and Methods in Development.

Uveal melanoma is the most common primary intraocular malignancy in adults, characterized by an insidious onset and poor prognosis strongly associated with tumor size and the presence of distant metastases, most commonly in the liver. Contrary to most tumor identification, a biopsy followed by a pathological exam is used only in certain cases. Therefore, an early and noninvasive diagnosis is essential to enhance patients' chances for early treatment.
