The study was conducted to profile optometrists and optometric practices in Ghana.An online survey among 146 optometrists, who were registered with the Ghana Optometric Association (GOA). It included questions on their demographics, equipment, ophthalmic procedures routinely barriers providing a full scope of services.Ninety (62 per cent) responded, mean age being 28.97 ± 3.36 years. There more males (68.9 than females most had Doctor Optometry (OD) degree, profession's highest degree Ghana....
To determine the relationship between some visual functions: colour vision defects, abnormal stereopsis, acuity and occurrence of road traffic accident (RTAs) among commercial vehicle drivers in central region Ghana, to assess their knowledge these anomalies.A descriptive cross-sectional study employing a multi-stage random sampling approach was conducted major towns within Ghana. Participants were taken through comprehensive eye examination after administration structured questionnaire.520...
To conduct the first ever population-based survey on ocular toxoplasmosis in Central Region of Ghana.A cross-sectional study was conducted three randomly selected communities Region, Ghana. Visual acuity (VA) measurement, dilated fundus examination by indirect ophthalmoscopy and serology testing were performed all participants. Ocular diagnosed based characteristic retinal lesions supported positive serologic using commercial enzyme-linked immunosorbent assay (ELISA) kits.A total 390...
Purpose . To determine normative values of retinal nerve fibre layer thickness (RNFL) and optic head (ONH) parameters their association with routine clinical tests such as refractive error (RE), stereoacuity (SA), contrast sensitivity (CS) in an African population. Methods In a cross-sectional observational study, 100 normal subjects aged 20 to 78 years were evaluated using the Cirrus HD-OCT 5000 matched 200 glaucoma patients. Results Average (±SD) RNFL for was found be 102.37 ± 7.45 (range,...
Purpose: To study the time course (onset, and duration of maximal cycloplegia, full duration) cycloplegic action 1% Cyclopentolate – Tropicamide.Methods: Seventy-seven students, aged 15-24 years were purposively sampled from University Cape Coast Technical Institute. Subjective near addition (ADD) determination pupil diameter measurement before after a drop test agent (1% Tropicamide combination in right eye) control left performed. Measurements subjective ADD made initial reading at 5...
To conduct an ocular health and safety assessment among mechanics in the Cape Coast Metropolis, Ghana.This descriptive cross sectional study included 500 using multistage sampling. All participants filled a structured questionnaire on demographic data, occupational history history. Study underwent determination of visual acuity (VA) LogMAR chart, external eye examination with handheld slit lamp biomicroscope, dilated fundus examination, applanation tonometry refraction.Out mechanics, 433...
To determine the accuracy of self-refraction (SR) in myopic teenagers, we compared visual and refractive outcomes self-refracting spectacles (FocusSpecs) with those obtained using cycloplegic subjective refraction (CSR) as a gold standard.A total 203 eligible schoolchildren (mean [±SD] age, 13.8 [±1.0] years; 59.1% were female) completed an examination consisting SR FocusSpecs adjustable spectacles, acuity logMAR (logarithm minimum angle resolution) chart, retinoscopy, CSR. Examiners masked...
This study aimed to investigate the correlation between convergence insufficiency symptom survey (CISS) score and signs of (CI) evaluate sensitivity specificity CISS predict CI ametropia among young adult university students.This prospective cross-sectional clinic-based included 300 first year students (mean age = 21.58 (SD ± 2.2) years) who consecutively reported for eye examination. Participants were administered questionnaire investigated CI. Diagnosis was based on presence three or four...
The study examined the ocular health of agricultural workers in fisheries sub sector with aim establishing a possible correlation between work place hazards and their health. A multi-stage random sampling (involving 683 subjects, 358 fishmongers 325 fishers) was employed. Ocular encountered at included seawater, sand or dust, heat, sunrays smoke. Exposure to these were found be associated irritation (P<0.001), tearing red eye gritty sensation blurred distant vision (P=0.001) near...
To investigate the refractive and non-strabismic binocular vision status of Optometry students in University Cape Coast, Ghana to establish any associations between these conditions. A cross sectional study 105 were taken through a comprehensive optometric examination status. Fisher’s exact test (IBM SPSS version 21) was used assess association Prevalence error dysfunctions 59.0% 34.3% respectively. specific errors 17.1% myopia, 19.0% hyperopia 22.9% astigmatism. Non-strabismic accommodative...
SIGNIFICANCE Cycloplegia is often restricted in screening settings. Previous studies have evaluated noncycloplegic refraction for screening, but their data are not fully applicable to school-aged African children. This article adds the literature by investigating this PURPOSE The purpose of study was evaluate ability autorefraction (NCA) and retinoscopy (NCR) detect refractive errors children quantify differences between cycloplegic measures. METHODS Autorefraction were performed on 150 aged...
Glaucoma is an optic neuropathy which causes irreversible vision loss. Standard perimetry, essential for glaucoma diagnosis, can only detect glaucomatous visual filed loss when considerable structural damage has occurred. Contrast sensitivity one of the function tests that reduced in eyes with glaucoma. It known to be affected pre-perimetric stages glaucoma.The objective this study was investigate discriminating ability central contrast perimetry and without employed a cross-sectional...
