Treatment Outcomes and Definition Inconsistencies in High-Risk Unilateral Retinoblastoma.

Purpose: To compare the clinical outcomes of children with unilateral retinoblastoma (Rb) and high-risk histopathology features (HRHF) following upfront enucleation with/without adjuvant chemotherapy, and investigate cases locally considered non-HRHF but converted to a standardized HRHF definition.

Design: Retrospective multinational clinical cohort study.

Methods: Children with Rb who presented to 21 centers from 12 countries between 2011-2020, and underwent primary enucleation were recruited.

Diffuse large cell lymphoma of the lacrimal sac may mimic as acute dacryocystitis.

A 36-year-old male patient presented with a firm swelling in the left lacrimal sac region with a history of recurrent episodes of acute dacryocystitis, which partly resolved with systemic antibiotics. Computed tomography showed diffuse soft tissue mass without bony erosion in the same area. Incisional biopsy confirmed diffuse large cell lymphoma of non-Hodgkin's type by histopathology and immunohistochemistry.

Pegylated interferon-alpha-2a for the treatment of ocular surface squamous neoplasia.

Ocular surface squamous neoplasia (OSSN) is the most common nonpigmented ocular surface neoplasm. Interferon-alpha (IFNα)-2b has been proved to be an effective immunotherapeutic agent to treat OSSN. We have used intralesional and topical (36 μg/ml) pegylated (peg) IFNα-2a to treat a recurrent surgically failed case of OSSN instead of IFNα-2b.

The role of maternal age & birth order on the development of unilateral and bilateral retinoblastoma: a multicentre study.

Background/objectives: Retinoblastoma is a common childhood intraocular malignancy, the bilateral form of which most commonly results from a de novo germline pathogenic variant in the RB1 gene. Both advanced maternal age and decreasing birth order are known to increase the risk of de novo germline pathogenic variants, while the influence of national wealth is understudied. This cohort study aimed to retrospectively observe whether these factors influence the ratio of bilateral retinoblastoma cases compared to unilateral retinoblastoma, thereby inferring an influence on the development of de novo germline pathogenic variants in RB1.

The Effects of Breastfeeding on Retinoblastoma Development: Results from an International Multicenter Retinoblastoma Survey.

The protective effects of breastfeeding on various childhood malignancies have been established but an association has not yet been determined for retinoblastoma (RB). We aimed to further investigate the role of breastfeeding in the severity of nonhereditary RB development, assessing relationship to (1) age at diagnosis, (2) ocular prognosis, measured by International Intraocular RB Classification (IIRC) or Intraocular Classification of RB (ICRB) group and success of eye salvage, and (3) extraocular involvement. Analyses were performed on a global dataset subgroup of 344 RB patients whose legal guardian(s) consented to answer a neonatal questionnaire.

Minimally invasive harvesting fascia lata (FL) in ophthalmic plastic surgery.

Purpose: To describe a minimally invasive technique of harvesting fascia lata, and also to analyze the clinical uses and of fascia lata in Ophthalmic Plastic and Reconstructive surgery.

Methods: This interventional study was done in three tertiary care eye hospitals in Bangladesh from July 2014 to June 2020. We obtained autologous fascia lata for the correction of congenital ptosis with poor levator function (⩽4 mm), covering the ciliary staphyloma, repair of the extruded implant following anophthalmic socket surgery, and was also used to wrap the orbital implant after enucleation.

Lag Time between Onset of First Symptom and Treatment of Retinoblastoma: An International Collaborative Study of 692 Patients from 10 Countries.

Background: The relationship between lag time and outcomes in retinoblastoma (RB) is unclear. In this study, we aimed to study the effect of lag time between onset of symptoms and diagnosis of retinoblastoma (RB) in countries based on their national-income and analyse its effect on the outcomes.

Methods: We performed a prospective study of 692 patients from 11 RB centres in 10 countries from 1 January 2019 to 31 December 2019.

Primary Conjunctival Pigmented Basal Cell Carcinoma with Increased Numbers of Intra-Tumour Melanocytes, Mimicking Melanoma: A Case Report and Review of the Literature.

A 60-year-old, South-Asian male patient presented with a dark brown lesion on his left conjunctiva surface near the limbus for 2 years. Examination showed a globular, dark brown-coloured mass near the temporal limbus at 4 to 5 o'clock position, measuring 3 × 3 × 2 mm. There were a few scattered flat pigmented lesions near the mass and also a few prominent vessels.

Results of Intralesional Bleomycin Sclerotherapy for Treatment of Orbital Lymphangiomas at a Tertiary Eye Care Centre in Bangladesh.

Purpose: The purpose of our study was to evaluate the role of intralesional bleomycin injection for the treatment of orbital lymphangiomas.

Methods: This was a prospective interventional case study. Twelve patients diagnosed with orbital lymphangiomas received intralesional bleomycin injection at a dose of 0.

Eyelid Metastatic Thyroid Papillary Carcinoma.

Purpose: The aim of this study was to report the clinical and histopathological features of an eyelid metastasis in a 70-year-old male with no prior medical history.

Methods: A 70-year-male presented with a painless, hard, red nodular growth in his left lower medial eyelid of 6 months duration, involving the canaliculus and punctum. He did not complain of any other ocular or systemic abnormality.

Lacrimal sac rhinosporidiosis: clinical profile and surgical management by modified dacryocystorhinostomy.

Purpose: To describe the clinical profile and surgical management of patients with lacrimal sac rhinosporidiosis.

Methods: This is a retrospective interventional case series. Eighteen patients, who were clinically diagnosed as isolated lacrimal sac rhinosporidiosis between October 2009 to January 2012, were included in the study.
