BackgroundAlbinism causes significant eye morbidity and amblyopia in children. The aim of this study was to determine the refractive state in patients with complete oculocutaneous albinism who were treated at the Gynaeco-Obstetric and Paediatric Hospital, Yaoundé, Cameroon and evaluate its effect on vision.MethodsWe carried out this retrospective study at the ophthalmology unit of our hospital. All oculocutaneous albino patients who were treated between March 1, 2003 and December 31, 2011 were included.ResultsThirty-five patients (70 eyes) diagnosed with complete oculocutaneous albinism were enrolled. Myopic astigmatism was the most common refractive error (40%). Compared with myopic patients, those with myopic astigmatism and hypermetropic astigmatism were four and ten times less likely, respectively, to demonstrate significant improvement in distance visual acuity following optical correction.ConclusionManaging refractive errors is an important way to reduce eye morbidity-associated low vision in oculocutaneous albino patients.
PurposeTo evaluate central corneal thickness (CCT) in a black Cameroonian population of ocular hypertensive and glaucomatous subjects.Material and methodsThis was a prospective study undertaken with an ultrasonic pachymeter from January 2009 to December 2009 in an eye clinic (INNEL Medical center) in Yaoundé, Cameroon.ResultsOne hundred subjects (200 eyes) were enrolled in the study. Sixty subjects were glaucomatous (primary open angle glaucoma, POAG group), and 40 ocular hypertensive (OHT group). The mean age of the sample was 52.60 ± 12.23 years. For the whole sample, CCT was 534.71 ± 37.95 μm in the right eye and 533.61 ± 37.67 μm in the left eye, with no statistically significant difference between the 2 eyes (P = 0.446). CCT in the POAG group was 526.30 ± 37.34 μm in the right eye and 524.90 ± 35.92 μm in the left eye. CCT in the OHT group was 547.32 ± 35.71 μm in the right eye and 546.67 ± 36.85 μm in the left eye. There was a statistically significant difference between CCT of the 2 groups (right eye: P = 0.013; left eye: P = 0.007).ConclusionMean CCT of ocular hypertensive subjects was thicker than CCT of glaucomatous ones in our Cameroonian sample. However, in both ocular hypertensive or glaucomatous patients, CCT of black Cameroonians is thinner than that reported in other studies in Caucasian populations.
OBJECTIVETo determine the main clinical indications for surgical removal of the eye in rural areas in Cameroon.DESIGNRetrospective non-comparative case series.PARTICIPANTSA total of 253 patients presenting to the Manna eye clinic Nkongsamba who underwent destructive eye surgery (DES) between January 2006 and December 2010 were reviewed.MAIN OUTCOME MEASUREAge, gender, occupation, prior medication, visual acuity, operation indications, and type of operation.RESULTSThere were 58.10% (n = 147) men and 41.90% (n = 106) women. Median age was 29 years (interquartile range: 14–69 years); age ranged from 10 to 88 years. A total of 67.19% (n = 170) of participants were farmers and lived in rural zones. In all, 79.05% (n = 200) confessed to have trying a medication before the presentation. Surgical indications included infective causes (perforated corneal ulcer 33.20% (n = 84) and endophthalmitis 18.20% (n = 46)), trauma 17.40% (n = 44), painful blind eyes 11.50% (n = 29), malignancy 10.70% (n = 27), and others 9.10% (n = 23).CONCLUSIONThe most common causes of DES in this series could be avoided. Therefore, preventive measures including extensive health education of the public and traditional healers on the risks linked to the use of traditional medicines in ophthalmology and the late presentation of eye disease, quality control of the campaigns that offer free cataract operations in the country.
The ocular flora can be a contributing factor to potentially devastating eye infections, especially under certain conditions such as diabetes. The aim of this study was to determine the influence of diabetes on the bacterial conjunctival flora and to assess its susceptibility to antibiotics. In an analytical cross-sectional study conducted in three hospitals in the department of Ndé-Cameroon, we included diabetic and non-diabetic participants. Samples were obtained by swabbing the lower conjunctival fornix. Gram stain and culture were performed and antibiotic sensitivity determined in case of bacterial growth. A positive culture was found in 33/40 (82.5%) diabetic participants and 16/40 (40%) non-diabetic participants. Diabetic participants showed a more frequent positive flora for Staphylococcus epidermidis, Bacillus, and Pseudomonas aeruginosa, while the majority of non-diabetic patient's flora were Bacillus, Staphylococcus epidermidis, and Staphylococcus saprophyticus. In diabetics, resistance of Staphyloccocus Coagulase-negative strains was observed in 80-100% of cases for Oxacillin and Trimethoprin-Sulfamethoxy. For Gram-negative strains, resistance was 80-100% for Penicillin, Oxacillin and Cefixime in diabetics. A positive culture was more frequently found in diabetic participants with a difference for the composition and antibiotic susceptibility compared to healthy people. This information may provide a better guideline for the prevention and the management of ocular diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
