Background: There are conflicting reports regarding the relationship between body mass index (BMI) and intraocular pressure (IOP). There is a need to evaluate these contradicting findings in our environment. Aim: To examine the relationship between intraocular pressure and body mass index (BMI) in a population screened for glaucoma at the Universit...

Background: Strabismus (ocular misalignment) is frequently seen in clinical practice. Its prevalence varies in different parts of the world with no sex predilection. Stabismus is a significant cause of ocular morbidity. Esotropia is often the commonest form of presentation among children. Aim: To determine the frequency and clinical features of pat...

Background: Macular holes are the common cause of visual impairment especially in the elderly and have a variety of etiological factors. The advances in the management of macular holes are encouraging and are now available in developing countries although scarce, where hitherto; patients seek attention outside their country. The need to understand...

To provide the types, frequency and clinical information on common cranial nerve palsies seen at the Eye Clinic at the University of Port Harcourt Teaching Hospital. A chart review was performed of patients who presented with cranial nerve palsy at the Eye Clinic over a 3-year period (January 2009-December 2011). Data were collected on age, sex, ty...

Optic neuritis is a demyelinating inflammatory disease of the optic nerve that typically affects young adults especially females, and is usually associated with multiple sclerosis especially in Caucasians. The prognosis for visual recovery is usually good but with poor quality. The objective was to determine the level of improvement of vision after...

The purpose of this study was to determine the prevalence and pattern of ocular injuries among industrial welders and rate the use of protective eyewear at work among industrial welders in Port Harcourt. Information from this study will provide a database for effective policy formation on prevention of occupational eye injuries in Port Harcourt Riv...

Idiopathic intracranial hypertension is a rare neurologic disorder which is largely self limiting and occurs as a result of increased intracranial pressure. Papilloedema is the most significant finding and may progress to visual loss. The case of a 45 year old obese female, who presented with a 9 month old history of headache and on examination was...
Article
Herpes zoster is a painful vesiculobullous dermatitis which occurs as a result of previously established varicella zoster virus infection. It is a well established fact that Herpes zoster ophthalmicus is a well known marker of human immune deficiency virus infection even in Africans. The aim of this study is to determine if indeed the herpes zoster...

... Tropicamide acts within 20 minutes and its duration of action is approximately 4-8 hours. 1 An elevation in IOP level has been observed after pharmacological mydriasis. 2 This IOP rise following pupillary dilatation may be attributed to the reduction in aqueous outflow secondary to the decreased traction on the trabecular meshwork resulting from ciliary muscle paralysis. 3 Moreover, iris pigment dispersion in the anterior chamber can cause obstruction of the trabecular meshwork representing a possible mechanism of IOP rise after mydriasis. ...
... This hypothesis has been supported by Ventura et al. [32], who found a disproportionate reduction in the pattern electroretinogram amplitude compared to retinal nerve fiber layer thickness. Additionally, a visual acuity improvement following trabeculectomy has been previously reported [33][34][35]. ...
... [6] Previous studies have shown the prevalence of neovascular glaucoma to be dependent on the prevalence of diabetes to some extent and the hospital prevalence of neovascular glaucoma has been found to be around 0.3% in some studies. [7,8] Glaucoma features are said to be more severe in cases in cases of proliferative diabetic retinopathy. ...
... [12] The reasons for nonperformance of ocular examination for patients underscore the need for training and motivation of GPs in ocular examination skill and roles in eye care as well as provision of basic ophthalmic equipment. Lack of essential equipment was also reported by Onua and Fiebai [13] in Port Harcourt, Nigeria, and as was lack of time by Raman et al. [14] in India as reasons by GPs for not examining eyes of patients. ...
... A sex ratio in pattern strabismus is rarely reported. Awoyesuku et al. [21] found the male: female sex ratio for strabismic patients to be approximately 2:5, while Azonobi et al. [22] reported a 3:1 sex ratio. The sex ratio of A-V pattern in infantile strabismus would be 1.21 based on the findings of Dickmann [23]. ...
... The prevalence varies in different parts of Nigeria. It accounted for 10 (4%) of retinal diseases in Benin city southern Nigeria [4] and 6.6% in South-South Nigeria [5]. In other studies carried out in Southwestern Nigeria, Macular hole constituted 4.2% -18% of retinal diseases seen during the study period [6] [7]. ...
... Vision may be affected by the complications of BRVO,including retinal macular edema (ME) [5], retinal detachment(RD) [6], the development of an epiretinal membrane (ERM) [7], and vitreous hemorrhage(VH) [8,9].Of such complications, ME is the most common. Secondary to chronic ME, VH was a common ocular complication in the past that caused impaired vision [3,10]. However, there has not been as much research on VH as on ME. ...
... 1,2,6-8,10-13 Furthermore, a 3-year retrospective review from Port Harcourt, Nigeria, reported an equal frequency of oculomotor and abducens palsy. 15 Common aetiologies of OMCNP in our study were microvascular ischaemia (25.6%), RTA (23.3%), and SOLs (14%). ...
... MS is more common in Western countries, whereas NMO has a higher prevalence in Asia [2]. Infection is also another important etiology of ON that needs to be considered [3]. ...
... The association between some exogenous substances, such as drugs, and the development of IIH is well documented. Tetracycline antibiotics (tetracycline, monocycline, doxycycline), vitamin A and other retinoids, as well as corticosteroid withdrawal, are considered to be the most frequent causes (6,9). For others however a causal relationship is uncertain: amiodarone, growth hormone, levodopa, cyclosporine, oral contraceptives, oxytocin, indomethacin, lithium carbonate (7,14,16,17). ...
