    Insights

    Retinoblastoma can occur in microphthalmic eyes, even in infants with 13q deletion syndrome. Multiple imaging techniques are crucial for diagnosis, as calcification may not be visible on CT scans alone.

    Area of Science:

    • Ophthalmology
    • Genetics
    • Pediatric Oncology

    Background:

    • 13q deletion syndrome is a genetic disorder associated with an increased risk of certain cancers.
    • Retinoblastoma is the most common primary intraocular malignancy in children.
    • Microphthalmia is a congenital condition characterized by abnormally small eyes.

    Observation:

    • A 10-month-old boy with 13q deletion syndrome presented with leukocoria (a white pupillary reflex) in a microphthalmic right eye.
    • The patient was diagnosed with bilateral retinoblastoma.
    • The right eye required enucleation, and the left eye was treated with laser, cryotherapy, and external beam radiation.

    Findings:

    • This case highlights that retinoblastoma can manifest in microphthalmic eyes.
    • Diagnostic imaging revealed calcifications on B-mode ultrasound that were not apparent on computed tomography (CT) scans.
    • This underscores the importance of utilizing multiple imaging modalities for accurate retinoblastoma diagnosis.

    Implications:

    • Children diagnosed with 13q deletion syndrome necessitate prompt and regular ophthalmological examinations to detect retinoblastoma early.
    • The findings emphasize the need for a comprehensive imaging approach, combining modalities like ultrasound and CT, for evaluating suspected retinoblastoma, especially in complex cases.
    • Early detection and appropriate treatment are critical for preserving vision and improving outcomes in pediatric retinoblastoma.

    The Retinoblastoma Gene01:20

    The Retinoblastoma Gene

    Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
    The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

    Meiosis I

    Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by a...

    Diabetic Retinopathy

    DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

    Genomic Imprinting and Inheritance

    Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
    The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
