Abstract :

INTRODUCTION: Orbito–ocular tumours emace neoplasia affecting all the tissues of the eye ball, the orbit with its contents and the ocular adnexae. Neoplasia in this rpart of trhe body can either be benign or malignant, primary, secondary or metastatic. Kaduna State is one of the states in the North–western part of Nigeria; a part of Nigeria that is dry, sunny and dusty most of the year. Demographic studies of orbito–ocular neoplasia in this state are a few and scanty

AIM: The aim of this study is to do a demographical analysis of the various histologically confirmed orbito–ocular neoplasia in Kaduna State

METHODOLOGY: This is a 5–years retrospective study spanning from January 2001 to December 2005 of 130 histologically confirmed cases of Orbito–ocular tumours retrieved from the laboratories of the Army Reference Hospital Kaduna and the Ahmadu Bello University Teaching Hospital Zaria. Analysis was done along the lines of the most common tumours, the age and sex distribution and the commonest tissue involved, using the Epi–info 6. The various orbito–ocular tissues and the histological diagnoses were all coded for easy data processing.

RESULTS: Out of the 130 orbito–ocular tumour cases reviewed 70 (54%) were females and 60 (46%) were male. The most affected age group was between the ages of 17–49 (45%). The commonest tissue involved in the study was the conjunctiva with 59 (45.4%) cases. Histo–pathologically, squamous cell carcinoma was the commonest orbito–ocular tumour in this study with 46 (35.4%) cases while 31 cases(23.8%) out of the 130 cases had retinoblastoma.

CONCLUSION: Orbito–ocular tissues can be involved in neoplastic changes and in our environment these pose serious challenges to both vision and life of the patients, particularly if neglected. In our study the conjunctiva was the most affected tissue, the males were less affected in our study in other studies.
