Study Notes
Extraocular Retinoblastoma Treatment
- Chemotherapy options include orbital, local, and systemic approaches.
- Radiation therapy is utilized in conjunction with other treatments.
- CNS disease treated with systemic chemotherapy and CNS-directed therapy.
- Trilateral retinoblastoma management may involve systemic chemotherapy followed by surgery and myeloablative chemotherapy with stem cell rescue.
Survival Rates for Retinoblastoma
- Up to 70-85% survival if treated intraocularly.
- 91% survival for Group A eyes; 84% for Group B eyes.
- If the optic nerve is involved, survival drops to 60% (Group C) and 30% (Group D).
- Untreated retinoblastoma has a poor prognosis with a survival rate around 7-85% if enucleated early.
Differential Diagnosis
- Dense cataract, persistent hyperplastic primary vitreous, Coats’ disease, ocular toxocariasis, retinopathy of prematurity, and retinal astrocytoma are considered in diagnosing retinoblastoma.
Retinoblastoma and Cataracts
- Cataracts can be congenital or acquired; can be bilateral or unilateral.
- Genetic mutations, metabolic disorders, syndromes, and trauma may contribute to cataract formation.
Persistent Hyperplastic Primary Vitreous Characteristics
- A congenital anomaly involving failure of the primary vitreous to regress.
- Presents as a gray-white retrolental membrane, often associated with conditions like microphthalmia.
Coats’ Disease Overview
- Characterized by leaky, dilated retinal vessels leading to progressive unilateral exudation, typically in children under 8 years.
- More common in males, presents with a yellowish fundus appearance.
Ocular Toxocariasis Information
- Caused by Toxocara canis/cati, presenting unilaterally with white granulomas in the posterior pole.
- Associated symptoms: pain, inflammation (vitritis, uveitis), and endophthalmitis.
Retinal/Astrocytic Hemangioma Clinical Features
- Benign, rare glial tumor, associated with tuberous sclerosis and neurofibromatosis.
- Appears as elevated gray-yellow-white masses, often asymptomatic but can present with leukocoria.
- Can obscure retinal vessels and has slow progressive enlargement.
Retinal Capillary Hemangioma Details
- Benign vascular tumor linked to von Hippel-Lindau syndrome, found commonly in ages 25-30.
- Characterized by small, well-defined orange-red nodules with dilated blood vessels, potentially resulting in exudation and retinal detachment.
- Can be asymptomatic or cause visual impairments depending on location.
Retinal Cavernous Hemangioma Features
- Benign, non-progressive vascular tumor, often unilateral and more prevalent in females in their 2nd to 3rd decades.
- Presents as purple-red saccular angiomas along normal retinal vein courses, with vitreous hemorrhage being a frequent complication.
Management Strategies for Retinal Tumors
- Treatment options for various retinal tumors include observation, laser photocoagulation, cryotherapy, anti-VEGF injections, and surgical interventions for complications.
