Retinoblastoma: The importance of early diagnosis.
CONCLUSIONS: This analysis included 58 eyes. There are no previous studies in our community and there are few series so numerous throughout the country. Based on non-standardised treatment, the most appropriate is chosen according to the characteristics of the tumour. The multidisciplinary management, formed by ophthalmology, paediatric oncology, radiotherapy, and radiophysical oncology, is fundamental for the selection of the most appropriate treatment. Chemo-reduction, along with consolidation treatments, offers encouraging results in the control of these tumours, especially in those of less severity. Enucleation continues to be the method of choice in the most advanced staging with vitreous involvement, with the importance of early diagnosis being highlighted.

Abstract Retinoblastomas represent 6% of all malignant tumors in children under 5 years old, which untreated lead to blindness in the affected eye and death due to metastases. The main symptoms are leukocoria and strabismus, which if possible, always necessitate a clarification within 1 week for exclusion of a retinoblastoma. The most frequent differential diagnoses are Coats' disease and persistent fetal vasculature (PFV) as well as other intraocular tumors, in particular astrocytomas. Systemic chemotherapy, if necessary in combination with laser hyperthermia, local chemotherapy and brachytherapy are the most imp...
ConclusionsOur demographic and basic clinical data for advanced RB are comparable to other similar reports. The tumor growth pattern correlates well with the type of seeding observed in enucleated globes with RB. Less tumor differentiation is a relative risk of massive choroidal invasion. It is advocated to implement the AJCC 8th edition by ocular pathologists worldwide aiming to histopathologically classify the RB tumor in cases for selective adjuvant chemotherapy.
Conclusion: Our experience suggests that IAC is a safe and effective treatment for patients with ICRB group B, C, D, and some group E retinoblastoma. Careful patient selection and experienced surgeons are critical for achieving the best treatment outcome.
We report 2 cases of iris heterochromia secondary to profound iris stromal depigmentation following intravitreal melphalan and topotecan injections.
Conclusion: The pathophysiology of choroidal ischemia is not well understood, but the fortuitous watershed zone preservation in this case could represent uneven distribution of the chemotherapeutic drug, resulting in partial chemo-dilution of the medication in the watershed region, which represents the final downstream overlapping choroidal perfusion from both medial and lateral posterior ciliary arteries.Ocul Oncol Pathol

The common presenting features of intraocular retinoblastoma (RB) include leukocoria (L), strabismus (S), and inflammation (I). Leukocoria has been associated with poorer ocular survival. Exotropia has been shown to be more common than expected in infantile strabismus. The impact of the combination of L and S presenting together has not been assessed. The need for enucleation at presentation and the use of adjuvant chemotherapy post-enucleation are recognised indicators of advanced disease.

Honavar, Kaustubh Mulay, Vijay Anand P. ReddyDiffuse anterior retinoblastoma is an infrequent presentation in which the tumor is confined to the anterior segment, and there is no retinal mass. An 18-month-old Asian Indian boy presented with white spots in the left eye. There were extensive anterior segment seeds without a retinal tumor. Fine-needle aspiration biopsy confirmed the diagnosis of retinoblastoma, and the patient received intravenous chemotherapy with ...
ConclusionsRetinoblastoma is often diagnosed at an advanced stage. With the development of systemic and local chemotherapy, the number of eyes with advanced retinoblastoma preserved by conservative therapy has been increasing.
