[Retinoblastoma at the Campus-University Teaching Hospital in Lomé, Togo, from 2014 to 2018]. / Le rétinoblastome au Centre Hospitalier Universitaire-Campus de Lomé, Togo, de 2014 à 2018.

INTRODUCTION: Retinoblastoma is a curable cancer when management is early and prompt. OBJECTIVE: To describe the epidemiological, clinical and therapeutic aspects of retinoblastoma. MATERIALS AND METHODS: A retrospective study was carried out from January 2014 to December 2018 (5 years) at the department of ophthalmology in Campus-University Teaching Hospital, Lomé, Togo. It focused on children with retinoblastoma. It included patients with diagnosis supported by ocular ultrasonography, orbito-cerebral computed tomography scan and/or histopathological examination. RESULTS: Among the 75 children with ocular cancer, 26 (34.7%) were diagnosed with retinoblastoma. The mean age at presentation was 31 months. The mean time from symptom onset to diagnosis was 15 months. A predominance of proptosis (65.4%), unilateral involvement (76.9%), extraocular tumor extension (65.4%) and endophytic form (96.15%) was found. Of the 32 eyes with retinoblastoma, 7 (21.9%) were enucleated after a mean time from diagnosis to enucleation of 6 months. Two cases of complete remission, 3 cases of tumor recurrence, and 2 cases lost to follow-up were noted. CONCLUSION: In our setting, retinoblastoma is a frequent childhood ocular cancer. It is important to improve the management of retinoblastoma as well as education of the parents.

[Association between consanguinity with the ocular congenital abnormalities in Togo]. / Association entre la consanguinité et les anomalies congénitales oculaires au Togo.

OBJECTIVES: To investigate the possibility of an association between parental consanguinity and the occurrence of congenital ocular abnormalities. MATERIALS AND METHODS: A retrospective cross-sectional study was carried out over 3 years, from January 2016 to December 2018, in the pediatric ophthalmology unit of the University Hospital Campus of Lomé (Togo). It included children with congenital ocular abnormalities. Age, gender, geographic origin (city or urban area, village or rural area), degree of consanguinity of parents and types of congenital ocular abnomalities were the variables of study. Odds Ratio (OR) and logistic regression were used to investigate the correlation between parental consanguinity and the occurrence of congenital ocular abnormalities. A P-value of<0.05 was considered statistically significant. RESULTS: Among the 103 patients with congenital ocular abnormalities, there were 60 (58.2%) males and 43 (41.8%) females. The mean age of the patients was 16 months, range 1 month-5 years. Patients born to consanguineous parents were 26.2% (27) of the total population. Of these 27 patients, 25 (92.6%) were born to second-cousin marriages and 24 (88.89%) came from a rural area. Parental consanguinity was correlated with developmental abnormalities of the globe (OR=37.50; 95% CI: [4.46-314.80]; r=3.62; P=0.00), sclerocornea (OR=13.04; 95% CI: [1.39-122.54]; r=2.57; P=0.02) and corneal dystrophy (OR=9.37; 95% CI: [0.93-94.36]; r=2.24; P=0.02). CONCLUSION: Our study suggests the existence of a correlation between parental consanguinity and the occurrence of congenital ocular abnormalities.
