Recent studies have reported conflicting results on the effects of biofouling on the adsorption behavior of microplastics (MPs). However, the underlying mechanisms driving the adsorption of MPs undergoing biofouling in aquatic environments remain unclear. This study examined the interactions between polyamide (PA), polyvinyl chloride (PVC) and polyethylene (PE) with two phytoplankton, namely cyanobacteria Microcystis aeruginosa and microalgae Chlorella vulgaris.

Materials And Methods: This was a nationwide web-based survey of ophthalmology trainers at the 30 institutions accredited by the National Postgraduate Medical College of Nigeria from April 2021 to June 2021.
Purpose: To determine the effect of clinical and cytological features of ocular surface disease on patient's satisfaction following small incision cataract surgery at a tertiary eye care centre.
Method: This is a prospective observational study of 70 consecutive consenting patients who underwent manual small incision cataract surgery(MSICS) at a tertiary eye care centre. All participants underwent ocular surface profile assessment using Schirmer I test (ST1), tear film break-up time (TBUT), conjunctival impression cytology (CIC) and ocular surface disease index (OSDI) at pre-operative visit, 1-week and 4-week post-operative visit.
Purpose: To assess morphological optic disc dimensions using spectral-domain optical coherence tomography (OCT) in a Nigerian population.
Materials And Method: Good quality SD-OCT scans of the optic disc of 147 eyes of 88 participants were selected, enrolled, and retrospectively reviewed. All subjects had optic nerve head and retinal nerve fibre layer OCT imaging, as well as analysis, done using the Topcon 3D OCT-1 Maestro.
The disease caused by viral pneumonia called severe acute respiratory syndrome coronavirus type-2 (SARS-CoV-2) declared by the World Health Organization is a global pandemic that the world has witnessed since the last Ebola epidemic, SARS and MERS viruses. Many chemical compounds with antiviral activity are currently undergoing clinical investigation in order to find treatments for SARS-CoV-2 infected patients. On-going drug-drug interaction examinations on new, existing, and repurposed antiviral drugs are yet to provide adequate safety, toxicological, and effective monitoring protocols.

Methodology: A comparative study of patients who had used topical preserved antiglaucoma medications for 6 months or more with age- and sex-matched individuals who were not on any other form of topical eye medication was carried out using fluorescein tear breakup time (FTBUT), Schirmer I test, and ocular surface staining with fluorescein and lissamine green. The right eyes of 103 eligible patients with primary open-angle glaucoma and that of 103 age- and sex-matched individuals (controls) were included in the study.

Introduction: intraocular pressure changes have been reported following the various cataract surgical technique. This study aims to compare the intra-ocular pressure (IOP) variation following conventional extra-capsular cataract extraction (ECCE), manual small incision cataract surgery (MSICS) and phacoemulsification in an indigenous black population.
Methods: a comparative cross-sectional study of adult patients aged 40 years and above who had pressure was measured with Goldman's applanation tonometer pre-operatively and 1 day, 1 week, 1 month as well as 3 month post-operative periods and recorded.
Purpose: The study aimed at determining the relationship between refraction and anthropometric measurements and the relationship between the level of education and refractive status in a Nigerian young adult population.
Materials And Methods: Healthy volunteers from the students and staff of a teaching hospital in South-Western Nigeria were studied. Demographic profiles including participants' highest educational status, parental educational level, and the age at first formal school enrollment were documented.
Introduction: We report a rare cause of keratitis, due to , in a farmer with keratomycosis. Despite the acknowledged virulence of this fungus, a suitable antifungal for its management was not accessible.
Case Presentation: A 67-year-old farmer presented with a two-week history of pain, mucopurulent discharge, redness and a corneal ulcer with a visual acuity of hand movement in the right eye.
Purpose: The study aimed at determining the associations between ocular biometry and anthropometric measurements in a Nigerian adult population.
Subjects And Methods: Participants were healthy members of staff and students of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. The height and weight were measured, and the body mass index (BMI) was calculated.
Objective: To determine the level of awareness and practice of use of protective eye devices among welders in Ile-Ife.
Methods: This is a cross-sectional descriptive study of 405 consenting welders. A pretested proforma was utilized to obtain information on sociodemographic characteristics, as well as awareness and use of protective eye device.
Purpose: To report a rare case of bilateral sporadic aniridia in an African child and review the management modalities.
Presentation: We report a case of bilateral sporadic aniridia with horizontal nystagmus, axial cataract optic disc, and fovea hypoplasia in a 5-year-old female patient. She was managed conservatively.
Purpose: To study the epidemiology of ocular trauma among the elderly in a developing country.
Method: This is a multi-center retrospective clinical study of patients aged 65 years and above managed for ocular trauma between 2001 and 2007 at 4 hospitals in southwestern Nigeria. Age, sex, occupation, residential address, location at time of injury, activity preceding injury, agent of injury, treatment modalities offered and presenting visual acuity were recorded in a predesigned form.
Purpose: To assess the prevalence and factors influencing previous dilated eye examination in screening for retinopathy among type II diabetics.
Methodology: Cross-sectional study of type II diabetic patients receiving treatment at a tertiary hospital in southwestern Nigeria was conducted with information on gender, age, duration of diabetes, current medication and previous dilated eye examination recorded. Eye examination included visual acuity, pen torch examination, applanation tonometry and direct ophthalmoscopy of the dilated eye in a dark room.

Background: Eye diseases are important cause of medical consultation in children, with the spectrum varying in different localities. This study aimed to determine the spectrum of childhood eye diseases in a tertiary hospital serving rural and semi-rural communities.
Methods: We conducted a retrospective review of all patients less than 15 years old who presented to the eye clinic of Wesley Guild Hospital Ilesa, Nigeria between January 2001 and December 2006.
Background: Orbital cellulitis is a medical emergency with potential vision and life threatening complications.
