1.What are the early symptoms of eye cancer?
Retinoblastoma presents with leukocoria (a yellowish-white reflex in the pupillary area), strabismus, and vision loss.Ocular melanoma may be asymptomatic in the early stages.
2.What are the common types of eye cancer?
Retinoblastoma is the most common type in children and has a genetic predisposition.Uveal melanoma—including melanoma of the iris, ciliary body, and choroid—is the most common type in adults.
3.What are the surgical treatment methods for eye cancer?
Treatment for retinoblastoma—laser therapy, cryotherapy, or enucleation—is selected based on the tumor stage.For uveal melanoma, small tumors are treated with local resection, while large tumors require enucleation.
4.What is minimally invasive treatment for eye cancer?
Laser photocoagulation and transpupillary thermotherapy are used for small retinoblastomas.Cryotherapy destroys tumor cells using low temperatures.Brachytherapy involves placing a radioactive plaque on the tumor surface.
5.Why is early detection of retinoblastoma important?
Early-stage tumors confined to the retina can be treated with laser or cryotherapy to preserve vision and the eyeball.Advanced tumors invading beyond the eyeball or metastasizing require enucleation or even combined radiotherapy and chemotherapy.
6.How effective are chemotherapy and radiotherapy for eye cancer?
Chemotherapy is used for systemic treatment and local arterial infusion in retinoblastoma.Intravitreal chemotherapy injections are used for vitreous seeding.Uveal melanoma is insensitive to chemotherapy.
7.How is follow-up conducted after eye cancer treatment?
Retinoblastoma requires lifelong periodic fundus examinations to monitor for recurrence and secondary malignancies.Uveal melanoma requires periodic monitoring for liver metastasis.Eyelid cancer requires periodic local examinations.
