An intraocular tumor is abnormal tissue growth that forms inside the eye. Tumors may arise from the retina, uveal tract, or other internal structures. Some are benign, while others are malignant and require urgent attention. Symptoms depend on the tumor's size and location. Early diagnosis helps protect both vision and overall health.
read more about intraocular tumor ...Causes vary widely. Some tumors form from pigment cells, such as choroidal melanoma. Retinoblastoma develops from genetic mutations in early childhood. Benign lesions like nevi may enlarge over time. Inflammatory masses can mimic tumors. Imaging and testing help distinguish these possibilities.
People may notice blurred or distorted vision. Floaters or flashes can appear if the tumor affects the retina. Shadows or field loss may develop with growth. Pain is uncommon unless the tumor increases pressure or causes inflammation. Some tumors are found incidentally during routine exams.
Ultrasound and optical imaging help measure size and depth. Angiography shows vascular patterns. MRI may be used to assess tumor type and spread. Genetic testing is used in children when retinoblastoma is suspected. Diagnosis relies on combining imaging, exam findings, and clinical history.
Treatment depends on the tumor type. Malignant tumors may need radiation, laser therapy, or surgical removal. Benign lesions are often monitored unless they grow. Retinoblastoma requires specialized pediatric care. Long-term follow-up tracks recurrence or progression.
No. Many are benign.
Large or untreated tumors can affect vision.
Imaging and regular exams track changes.
Seek care for new flashes, shadows, or unexplained vision changes.
