i.    Pattern of neuro-ophthalmic disorders in Ibadan

This research started as a pilot study in September 2014. It was a retrospective review of clinical cases seen in the newly established neuro-ophthalmomolgy unit. It was purposed as a needs assessment; to determine the personnel, infrastructural and skills requirements for successful initiation and maintenance of a clinical neuroophthalmology service and to define focused training goals for medical students, residents and potential neuro-ophthalmology subspecialty fellows in the University College Hospital, Ibadan. The project has reached the stage of data analysis and reporting. It should be submitted for publication soon.

ii.  Visual outcome of surgically operated sellar and parasellar tumours

This clinic-pathological study retrospectively reviewed cases of sellar and parasellar intracranial tumours assessed for neuro-ophthalmological status prior to neurosurgical intervention. The postoperative outcome was compared with clinical presentation as well as the histological and radiological findings. Analysis is aimed at identifying possible factors responsible for, or contributing to, the universally poor visual outcome. The difficulty with this study has been with the retrieval of histological records and post-operative outcomes. The data is still being collated.

iii.   Causes of delay in presentation of visually significant intracranial tumours/pathologies

Prospective data was collected from 50 consecutive patients reporting to the neuroophthalmology clinic with visual complaints related to neurological or neurosurgical disease. These patients were either referred from the other neuroscience specialties or first time patients to ophthalmology clinic. Data entry has been completed. The study is at the stage of data cleaning.

iv.  Visual assessment in cerebral palsy

This is an observational study of the pattern of visual impairment and neuroophthalmic presentation of children with cerebral palsy. It will describe the methods used in assessing vision in these children within the context of a limited resource setting. The outcome and compliance with recommended prescriptions will also described. The study is at the stage of data entry.

v.   Thyroid eye disease in Ibadan

This is a prospective multidisciplinary study that is being carried out between ophthalmology, endocrinology, general surgery and nuclear medicine. It aims to describe the pattern of presentation and management of thyroid-related diseases in Ibadan, while working to develop an acceptable guideline for the clinical investigation, management and follow-up of patients in the context of a resourcelimited setting. Though data collection is on-going, at least two preliminary reports have been published in peer-reviewed journals.
