Diagnosis Path: Diagnosis typically involves an array of examinations and tests, such as: - Comprehensive eye examination to assess visual acuity, eye movements, and physical abnormalities - Imaging studies like MRI or CT scans to evaluate the extent of the tumor - Biopsy procedures to obtain tissue samples for histopathological analysis - Additional tests to rule out metastatic disease if suspected Early diagnosis relies on a high index of suspicion, especially when symptoms persist or worsen.

Treatment Protocols: Treatment options depend on the size, location, stage of the tumor, and overall health of the patient. Common approaches include: - Surgical removal of the tumor or affected gland - Radiation therapy to target residual cancer cells - Chemotherapy or targeted therapy in cases of advanced or metastatic disease - Supportive therapies to manage symptoms and preserve vision Multidisciplinary care involving ophthalmologists, oncologists, and radiologists is essential for optimal management. Due to the rarity of this condition, treatment plans are often tailored to individual cases and based on the latest medical research.
