Retinoblastoma is a rare malignant tumor of the retina usually seen in children before 5 years of age. The tumor is extremely rare in adults. We report here an unusual case of retinoblastoma in a 55-year-old adult female who presented to us with an orbital mass at a late stage of the disease. Detailed laboratory investigations and imaging studies could not make a precise diagnosis. The treating ophthalmologist suspected primary intraocular tumor, metastatic carcinoma, malignant melanoma, or lymphoma and referred the patient for fine needle aspiration cytology (FNAC). Cytopathological examination of Giemsa-stained FNAC smear was consistent with that of retinoblastoma and established the diagnosis.

Background: Strabismus is a potential cause of ocular morbidity.
Objective: The aim of this study was to determine the frequency, types of manifest strabismus and co-morbidities among patients attending a referral paediatric ophthalmology and strabismus clinic in Calabar, Nigeria.
Methods: A retrospective review of case-notes of patients attending the paediatric ophthalmology and strabismus clinic from January 1, 2017 to December 31, 2019 was done.

One in 16, 000 live births is affected by the retinal tumor RB (retinoblastoma), which is frequently found in a child's early years. Both of the RB1 alleles that have been locally mutated in the affected retina are present in 60 percent of cases. Retinoblastoma (RB) can be detected using a variety of techniques, including imaging of the brain and orbits, eye examinations under anesthesia (EUAs), and the discovery of cell-free tumor DNA in samples of aqueous humor or plasma.

Plants respond to higher ambient temperatures by modifying their growth rate and habitus. This review aims to summarize the accumulated knowledge obtained with Arabidopsis seedlings grown at normal and elevated ambient temperatures. Thermomorphogenesis in the shoot and the root is overviewed separately, since the experiments indicate differences in key aspects of thermomorphogenesis in the two organs.

Objective: The aim of this systematic review and meta-analysis was to qualitatively and quantitatively evaluate the current evidence on the significance of the loss of early stages of oral carcinogenesis in lesions diagnosed according to clinical and/or histopathological criteria and their evolution to oral cancer.
Materials And Methods: We searched MEDLINE (through PubMed), Embase, Scopus and Web of Science for primary-level studies published before November 2024, designed as prospective or retrospective longitudinal cohorts, and not restricted by language or publication date. The risk of bias was critically assessed using the QUIPS tool.

Intraocular malignant tumors are rare; however, they can cause serious life-threatening complications. Uveal melanoma (UM) and retinoblastoma (RB) are the most common intraocular tumors in adults and children, respectively, and come with a great disease burden. For many years, several different treatment modalities for UM and RB have been proposed, with chemotherapy for RB cases and plaque radiation therapy for localized UM as first-line treatment options.
