Background: Primary Open-Angle Glaucoma (POAG) is a chronic, progressive optic neuropathy of multifactorial origin defined by alterations in the visual field, progressive loss of optic nerve fibers and ganglion cells, and an open iridocorneal angle in gonioscopy. It is the world's leading cause of irreversible blindness. There is no epidemiological study in Guinea that allows us to locate the real level of the problem. The objective of this study is to determine the hospital incidence of POAG at the Centre Médical Communal (CMC) in the Flamboyants. Patients and Method: This was a descriptive cross-sectional study with a prospective collection for one year, from April 1, 2020 to March 31, 2021, in patients aged at least 40 years, received in consultation at the CMC in the Flamboyants. The diagnostic criterion for a new case of glaucoma was the presence in a patient of the following two signs: (excavation of the optical disc C/D ≥ 0.5 and alteration of the visual field) with an open angle at least stage 4 of the Shaffer and Etienne classification associated or not with ocular hypertonia and having never received anti glaucoma treatment. We described variables related to sociodemographic characteristics, visual acuity, intraocular pressures, papillary excavations, and visual field surveys. Informed consent from patients was sought and obtained. The confidentiality of the files was guaranteed. Results: 68 new cases of POAG were diagnosed out of 3220 consultations, an incidence rate of 2.11%. The average age was 58.2 years (10.64 with a male predominance of 63.23%. A family history of glaucoma was present in 11.36% of cases. Visual acuity was poor < 1/10 in 79 eyes/136, average between 1/10 and 3/10 in 11 eyes/136, and good ≥ 3/10 in 46 eyes/136.
Background: Cataract is the leading cause of blindness in the world and its treatment is exclusively surgical. However, the results of cataract surgery are not always as good as is assumed and this aspect of surgical services needs a lot of attention. The purpose of this study is to evaluate the functional results of the free cataract surgery campaign carried out at the Siguiri Prefectural Hospital in Guinea. Patients and Method: This was a descriptive and retrospective cross-sectional study over a period of three months (1 October-31 December 2017). Records of cataract-operated patients during the study period were reviewed. The complete files for the main variables sought were retained. Sociodemographic data and visual acuity without pre-and post-operative correction were assessed. Functional outcomes were analysed according to WHO guidelines and recommendations for post-operative functional outcomes of cataract surgery. The data was collected and processed using Excel version 2010 software. Results: A total of 108 eyes from 102 patients were the subject of this present study on 314 eyes from 289 operated patients. 64 (%) men and 38 women (%) had a follow-up of 6 weeks after cataract surgery, a sex ratio of 1.68 in favor of women. The average age was 62.45 ± 15.20 years with extremes of 25 and 90 years. The age group from 60 to 69 years is the most represented with 46 cases or 45.45%. Housewives and farmers are the most represented strata with 42 cases (41.18%) and 31 cases (30.39%) respectively. The operative technique was Phaco A in 4/5 of the cases. No implant calculations were performed. Functional results indicate that 66% of patients had good visual acuity (≥3/10); 29% of patients had borderline visual acuity (between 1/10 and 2/10) and 13.30% had poor visual acuity (<1/10
Purpose The last Ebola outbreak severely affected West Africa and led to 2543 deaths and 1268 survivors in Guinea, where it began. The survivors faced various symptoms and disorders including ocular pain and erythema, itching, tearing, photophobia and blurry vision. The purpose of our study was to describe uderluing ocular diseases. Methods This is a prospective observational multicenter cohort study initiated in March 2015 which included survivors followed up in the infectious disease ward of Conakry and Nzérekoré. The patients received multidisciplinary medical follow‐up that included an eye examination. Results Systematic examination of 341 survivors highlighted 46 cases of uveitis (13.5%), six episcleritis (1.8%), and three interstitial keratitis (0.9%). Uveitis were more unilateral (78.3%) and anterior (47.8%) and occurred within the 2 months following discharge from the Ebola treatment center. Moreover, relapses were found up to 13 months after healing. Eleven eyes with anterior chamber inflammation presented with cataracts and visual acuity ≤ 5/10. Ten eyes with chorioretinal scars presented decreased visual acuity ≤ 5/10. Among 46 survivors with uveitis, 13 (28%) suffered from visual alteration on at least one eye. Conclusions Nearly 17% of Ebola survivors presented ocular disorders that may be very delayed in some patients. Moreover our study brought out relapses. We were not authorized to take intra‐ocular samples to identify the virus. The mechanism behind these uveitis is probably is an association between a direct cytopathic impact of the virus and an immune reaction to it. The corticosteroid therapy that is actually recommended by WHO can't be used safely during the acute infection but seems to be efficient in survivors. The current issue is to perform safely cataract surgery in survivors.
Introduction: Eye trauma represents all morbid lesions on the eyeball due to external violence. In children, they are an important cause of morbidity and the leading cause of monocular blindness. The aim of this study was to determine the sociodemographic, clinical and therapeutic characteristics of eye trauma in children aged 0 to 16 at the Application Centre for the Diploma of Specialized Higher Studies in Ophthalmology (CADESSO) in Donka, Guinea. Patients and Method: This was a prospective longitudinal study with descriptive purposes from January 1 to December 31, 2019 involving 205 children victims of eye trauma. Variables related to sociodemographic, clinical and therapeutic characteristics were studied. Informed consent from patients and/or their parents was sought and obtained. The confidentiality of the files was guaranteed. The data entry was done on EPI-Info version 7 and the analysis using the Stata software. The tables were made in Excel 2010. Pearson's Chi2 test was used for the comparison of proportions. Results: Pediatric eye trauma accounted for 9.31% of pediatric visits and 30.92% of all eye trauma cases. There was a male predominance with a sex ratio of 1.59. Age groups from 0 -4 years; 5 -8 years and 9 -12 were the most affected with 26.8%, 28.8% and 27.3% respectively and a decrease in the number of cases in the 13 -16 age group (17.1%). Gambling and sports accidents accounted for 33.2%, followed by domestic accidents for 16.6% and physical injury for 8.2%. Eye contusion was the most represented at 66.3% followed by wounds of the globe 23.9% and burns at 5.9%. One hundred and twenty-six patients had received a determination of visual acuity (VA) at admission; 99 were assessed at dis-
