PurposeTo determine the prevalence of color vision deficiency (CVD) among first-cycle students of the Faculty of Medicine and Biomedical Sciences of the University of Yaoundé I.Patients and methodsA cross-sectional descriptive study was carried out between October 1, 2015 and May 31, 2016. Distant visual acuity was measured and color vision test done for all consenting students. Ishihara’s plates were used to test all the participants. Those who failed the test were tested with the Roth’s 28 Hue test for confirmation of CVD and classification.ResultsA total of 303 students were included, among whom 155 were males (50.8%) and 148 were females (49.2%). The mean age was 20.2±2 years. Five students (1.6%) failed the Ishihara’s plate testing. Roth’s 28 Hue test confirmed CVD in 4 of those cases, giving a prevalence of 1.3%. There were equal numbers of protan and deutan CVD.ConclusionDespite its low prevalence among first-cycle students of the Faculty of Medicine and Biomedical Sciences, CVD screening should be performed in order to raise awareness, which will go a long way to help orientate the choice of future specialty.
Aim. To report the case of congenital bilateral upper eyelid eversion with severe chemosis that was successfully managed conservatively. Report. The patient was a six-hour-old male neonate with bilateral congenital upper eyelid eversion and severe chemosis, following uneventful delivery. Conservative management consisted of the application of antibiotic ointment and padding the exposed conjunctiva with 5% hypertonic saline-soaked gauze. The eyelids reverted spontaneously on day 3 and the condition was completely resolved by the third week. Conclusion. Congenital upper lid eversion is usually a benign condition which responds well to conservative treatment. Creating awareness amongst healthcare professionals is essential.
Purpose: To report the case of Phthirus pubis infestation of the eyelashes presenting as chronic blepharoconjunctivitis. Case Report: A 6-year-old girl presented with a 2-month history of blepharoconjunctivitis unresponsive to topical antibiotics in the left eye. Slit-lamp examination revealed the presence of nits and adult parasites on the eyelashes. Parasitological examination confirmed adult forms and nits of Phthirus pubis. There was no evidence of infestation elsewhere. Outcome was favourable with mechanical removal and application of petroleum jelly. Conclusion: Careful slit-lamp examination of the eyelashes should be done in all patients presenting with ocular irritation symptoms.
Objective:To determine the indications and rate of acceptance for destructive eye surgeries at the ophthalmology unit of the Yaoundé Gynaeco-Obstetric and Paediatric Hospital.Methods:A retrospective consecutive case series in which the medical records of all patients consulting in this unit over a 9-year period (2002 to 2010) were reviewed. Records in which destructive surgery was recommended were retained. Information collected included demographic data, eye affected, clinical diagnosis, acceptance or refusal of surgery, and the outcome in those in whom surgery was performed.Results:A total of 48 patients had a recommendation for destructive eye surgery, of whom 30 (62.5%) were males and 18 (37.5%) were females. Mean age was 43.78 (SD = 28.11; range 1 month to 91 years). Children <10 years comprised 23.10%. The leading causes were endophthalmitis/panophthalmitis (47.9%), neoplasm (20.8%), and absolute glaucoma (14.6%). Surgery was done in 20 cases (41.7%). Evisceration was the most performed surgical procedure (50%), with endophthalmitis/panophthalmitis and neoplasm combined accounting for 65% of surgeries.Conclusion:The high rate of refusal is an indication of the psychological devastation undergone by patients or the families of children in whom eye removal is recommended. Awareness should be raised on preventive measures and the need to rapidly seek eye care.
Background:Intraorbital abscess is a very severe infection with ophthalmologic and neurologic complications that are sometimes life-threatening.Objective:To report the etiologic, clinical, radiologic, and prognostic features of one case of bilateral intraorbital abscesses with intracranial complications.Case report:A 15-year-old Cameroonian girl in a comatose state (11/15 on the Glasgow Coma Scale) with meningeal signs, right hemiplegia, right facial palsy, and bilateral exophthalmia was admitted for meningitis and cerebral abscess secondary to orbital cellulitis. A lumbar tap was carried out, no organisms were seen by Gram stain, and culture was negative due to previous antibiotic therapy. A computed tomography scan showed a left internal capsule infarct and a pansinus opacification. Bilateral superior orbitotomies were performed and the abscess evacuated. Microscopy and culture of surgical material were negative. The patient was discharged 4 weeks after hospital admission with a visual acuity of 0.1 in both eyes, aphasia, and right hemiplegia. Nine months later, there was complete visual recovery (visual acuity 1.0 in both eyes). Anterior and posterior segments were normal on slit-lamp examination. There was no aphasia, but right-sided hemiparesis persisted.Conclusion:The authors emphasize the need for prevention, early diagnosis, and adequate treatment of orbital cellulitis in order to avoid complications.
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.
