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

Introduction: Trachoma is a chronic keratoconjunctivitis caused by Chlamydia trachomatis bacteria. An epidemiological study was conducted in 2014 in the Health District of Fria (Northern Guinea province) to assess the prevalence of active and scar trachoma in a suspected endemic area of approximately 120-135 inhabitants. This is a transversal, descriptive, clustered survey of a representative sample of the population according to the standard protocol recommended by the World Health Organization (WHO). The clinical review of target populations was conducted according to WHO codification. Of the 3173 subjects recorded, 3159 subjects consented to be examined or an examination rate of 99,55%. The prevalence of active trachoma was 8.67% (CI at 95% = 7.2-10.4). The prevalence of scar trachoma was 0.21%. The principal sources of water for households are surface water (41%) and drilling water (41%). The prevalence of active and scar trachoma, risk factors are discussed. In our study, trachoma appeared as a public health problem in the health district of Fria. The prevalence of active and scar trachoma is approaching WHO limit. Poor hygiene was the main risk factor. The implementation of the different components of the strategy SAFE in this locality is a necessity.

Introduction: Idiopathic central serous chorioretinopathy (ICSC) is characterized by the buildup of fluid leading to circumscribed elevation of the retina within the posterior pole. This condition affects young people between the ages of 20 -50 years. The disease is seen predominantly in men as compared to women. We report the cases of two (02) patients received in consultation at IOTA-Teaching Hospital between July 2019 and February 2020. Case Presentation: We report two cases of Idiopathic stress central serous chorioretinopathy. The first case is a 37-year-old man that we received in consultation for visual acuity decrease from a sudden installation for 1 hour. The clinical and paraclinical arguments permitted us to retain the diagnosis of Idiopathic stress central serous chorioretinopathy. The patient benefited from laser treatment and the clinical evolution was good. The second case is a 42-year-old man, who consulted for a sudden reduction of visual acuity that had been evolving for 3 weeks. The clinical and paraclinical contexts were in favour of the diagnosis of Idiopathic stress central serous chorioretinopathy. The patient was treated with spironolactone. The clinical evolution was favourable. Conclusion: Our study confirms the existence of central serous chorioretinopathy (CSC) in Black African patients. Studies show the connection between CSC and stress.
