Background: Large papillary excavations constitute a true differential diagnosis of glaucoma in our environments. Aim: To present a clinical case of large papillary excavation simulating glaucomatous optic neuropathy in a young subject. Case Presentation: The ophthalmologic examination made it possible to note a visual acuity of LogMar 0.00, ocular hypertonia and a large papillary excavation in both eyes. The visual field noted bilateral perimetric involvement suggesting optic neuropathy. Optical coherence tomography (OCT) of the ganglion complex revealed an absence of involvement of the ganglion complex and the ganglion ridge essential to evoke optic neuropathy. An ocular hypotonizing treatment made it possible to normalize the intraocular pressure. Conclusion: The particularity of this observation lies in the fact that the perimeter involvement that preceded any involvement can simulate a glaucomatous involvement. Functional damage to the visual field must be correlated with structural damage to suggest glaucomatous damage in our ophthalmic patients.

Background: Although proptosis is rare, it is nevertheless the main sign of orbital disease. Its discovery usually indicates a serious eye disease especially in children. Objective: To determine epidemiological and diagnostic aspects of childhood proptosis in Lome (Togo). Methods: Retrospective cross-sectional study conducted from June 2010 to May 2020, which is 10 years, in the ophthalmology department of CHU-campus of Lome. Files of patients between the age of 0 and 15 who presented a proptosis during the study period were taken into account in the study. Patients with a false proptosis or incomplete records during the study period were not taken into account in the study. Results: The study considered 42 children with an age average of 7.63 years ± 4.96 [4 days;15 years] and a sex-ratio of 1.33. The frequency of proptosis was 0.5% with an average progression of 383.7 days before the first consultation. The proptosis was unilateral in 80.95% of cases. The orbito-cerebral CT scan was done in 47.62% of cases. The proptosis in these patients was predominantly of grade 3 in 45% of cases. The tumor pathologies were at the forefront in 35.71%, dominated by retinoblastoma, and followed by infectious and inflammatory diseases in 14.29%. Conclusion: Childhood proptosis is rare and often indicative of infectious and tumor pathologies in our context. Its diagnosis is delayed, which shows the importance of an early and effective diagnosis. .

Aim: To evaluate results of cataract surgery in Eye Camp in rural areas. Patients and Method: This study set about the retrospective analysis of cases and operating reports of patients over the age of 10, operated for cataract in Eye Camp and fixed strategy from January, 2010 to December, 2012. Postoperative data were specified and compared. Results: Out of a total of 1145 patients operated, 577 (50.40%) were men compared with 568 (49.60%) women. The general mean age was 62 years, similar in Eye Camp and in fixed strategy. Sixty percent of patients were operated in Eye Camp. After 4 weeks of follow-up, 77% of patients were met again, and 83% among them showed good results (corrected visual acuity = 3/10). This rate of good results was 80.43% in Eye Camp against 87.7% in fixed strategy. We noted 18.25% of complications among which 11.25% were in Eye Camp. The functional outcomes of both strategies get closer to WHO standards. Conclusion: Eye Camp in the Central Region of Togo is an interesting alternative that contributes to the fight against blindness, even if postoperative follow-up is still to be improved.

Background: Druses of the papilla constitute abnormal deposits of calcified hyaline material at the level of the head of the optic nerve. They can be superficial or deep. Aim: The aim of this study is to show the utility of ocular ultrasound in ophthalmology in underdeveloped countries for the characterization of optic disc druse. Case Presentation: Our study relates to a clinical observation of buried papillary druses diagnosed by ocular ultrasound. The ophthalmologic examination revealed an aspect of false papillary edema in the fundus. The ocular ultrasound revealed hyperechogenic deposits buried in the papillary margins, which suggests the deep papillary druses. Conclusion: Ocular ultrasound still has a prominent place in the diagnosis of certain eye conditions despite the new sophisticated means available to ophthalmology to date.

Many general conditions have an impact on the fundus. The purpose of our work was to study the epidemiological profile of patients referred to our service for a review of the fundus and analyze the results. It was a retrospective study description of the examinations of the fundus during the period from January 2016 to December 2017. In the ophthalmology department of the Lomé University Hospital Center, during the study period, 1019 consultations were recorded, of which 727 were for fundus 6.84%. There were 336 men and 391 women, a sex ratio of 0.85. The age group 40 - 69 years accounted for 61.9%. The frequency of the main reasons for the request was hypertension 54.2% (N = 394);hypertension complicated or associated with other conditions (CKI, CKD, pregnancy and diabetes) accounted for 21.6% (N = 157), headache associated with a decrease in visual acuity 8.25% (N = 60), diabetes 6.46% (N = 47) and sickle cell disease 0.69% (N = 5). Hospitalized patients 52.41% (N = 381). The fundus was abnormal in 546 patients or 75.11%. Hypertensive retinopathy was found 80.21% cases in hypertensive patients, diabetic retinopathy 43.42 in diabetic patients. Diabetics Fundus examination in hospital practice found a retinal lesion in three-quarters of cases. It so important to ask the examination of the fundus most often in the current pactise.

Introduction: Glaucoma is a major cause of irreversible blindness worldwide. Early detection and awareness are essential to reduce the impact on eye health. The aim of this study is to assess the knowledge, attitudes and practices of health care staff about glaucoma in Lomé. Materials and Methods: This was a prospective cross-sectional and descriptive study including health care staff in Lomé, from October 1st to December 31st, 2020, for a period of 3 months. After their agreement, the officers responded to questions based on a survey sheet. Results: A total of 169 agents from 3 centers in Lomé, i.e. the Sylvanus Olympio University Teaching Hospital, the Campus University teaching Hospital and the Bè Hospital were involved. 50.9% of the agents were male versus 49.1% female, i.e. a ratio of 1.04. The average age was 33.66 ± 10.45 years. 46.10% were doctors versus 53.90% paramedics. 58.60% had at most 5 years of experience against 41.40% who had more than 5 years of experience. 53.80% defined glaucoma as ocular hypertension while 17.20% defined it as optic nerve disease. 46.20% did not know that there were many types of glaucomas compared to 53.20% who knew that there are many types of glaucomas. 92.30% knew that glaucoma can lead to cause visual loss. Regarding attitudes and practices about glaucoma, 91.70% declared that the follow-up should be done by the ophthalmologist, 81.10% thought that it would be necessary to be checked by the doctor only every 6 months. Finally, 65.08% declared that they had to use eye drops for life for the treatment. Conclusion: Steps should be taken to educate staff more about glaucoma attitudes and practices and also plan for action in the population.

Background: Ocular coloboma is the product of an error in the fetal fissure closure, normally occurring between the fifth and sixth weeks of gestation [1]. It may involve the cornea, iris, zonula, ciliary body, choroid, retina and optic nerve. The incidence of this syndrome is 0.7 per 10,000 live-births [1]. The aim of this observation is to present the first case of bilateral coloboma of the iris [1]. This case was associated with an ametropia causing a decrease in visual acuity. Case Presentation: This was a clinical observation concerning a young 12-year-old patient who consulted for blurring of vision which had progressed for approximately 2 years. The ophthalmologic examination revealed an ametropia with a bilateral notch of the pupillary rim suggesting a bilateral coloboma. There was no association with another coloboma such as chorioretinal coloboma which is quite common and is accompanied frequently by visual symptoms. Conclusion: A visual impairment of the child can indicate ametropia. However, other congenital anomalies can be discovered as was the case in this clinical observation.

Objective: Maculopathies are more and more frequent. For the follow-up of its evolution and therapy, it seems important for us to determine the baseline in normal subjects by Optical Coherence Tomography (OCT). The goal here is to determine the acceptable range of macular thickness in normal black subjects in Lomé. Methodology: This is a retrospective study over a 6-month period. It did not include all patients with retinopathy of any cause, maculopathy, and glaucoma. The analyzed variables were the average macular thickness, the central macular thickness, and the total macular volume. Results: Out of the 433 macular OCT performed, 191 patients were selected;a total of 338 eyes. These included 96 men and 95 women. A sex ratio was 1.01. The median age was 44.1 years with extremes ranging from 10 to 70 years. The average macular thickness was 263.4 μm for the right eye and 263.7 μm for the left eye. The central macular thickness was 174.1 μm for the right eye and 173.3 μm for the left eye. The total macular volume was 7.4 in both eyes. Discussion: No significant statistical difference existed between the two sexes. The average macular thickness found in this study was within the range of normality observed in the literature, which is between 216 and 288 μm. Conclusion: The average macular thickness of the normal subject in Lomé was 263.4 μm.

Purpose: To identify the pathologies of the vitreoretinal interface by Optical Coherence Tomography OCT of the retina in Lomé. Methodology: This is a retrospective analytical study, carried out in a specialized liberal center in Lomé. It was based on the analysis of OCT images of the retina, carried out with patients between October 2012 and October 2014. The variables collected were the socio-demographic characteristics, which were the various pathologies of the vitreoretinal interface. Results: 303 eyes of 164 patients were analyzed. The population was predominantly female (sex ratio = 0.95) aged 9 to 84 years with an average of 52.93 years. 121 eyes (39.9%) had posterior vitreous detachment with 66.1% in the 50 - 70 age group. 42 eyes (13.86%) presented vitreomacular traction with 66.6% in the 50 - 70 age group. 31 eyes (10.23%) presented an epi-retinal membrane with 61.2% in the 50 - 70 age group. 33 eyes (10.89%) had a full-thickness macular hole with 69.6% in the 50 - 70 age group. 4 eyes had a lamellar hole and 1 eye had a pseudo hole. Conclusion: OCT is an excellent tool for non-invasive exploration of the vitreoretinal interface. It gives precise information on the various pathologies of this interface. The need to evaluate the functional impact of these abnormalities, calls for other studies, especially prospective studies to assert their reality of those disease.
