[Pterygium surgery with sutureless, glueless conjunctival graft: Preliminary study at the Centre hospitalier universitaire de Cocody in Abidjan]. / Chirurgie du ptérygion par greffe conjonctivale sans suture ni colle biologique : étude préliminaire au centre hospitalier universitaire de Cocody à Abidjan.

PURPOSE: To optimize the pterygium management by delineating the role of sutureless, glueless conjunctival graft. MATERIALS AND METHODS: This was a prospective cohort study carried out at the Centre hospitalier universitaire de Cocody between October 1st, 2021 and March 31st, 2022. It analyzed a series of 36 cases of stage I, II and III pterygium by Cornand's classification, who underwent surgery by a sutureless conjunctival graft technique without biological glue. RESULTS: Demographically, 33.3% of our study population were between 30 and 40 years of age, with a mean of 47.86 years. The patients showed a female preponderance, 53%, with a male:female ratio of 0.89. At the clinical level, 75% of our population presented for ocular redness, 84% had a nasal pterygium, and 75% were stage 2. In terms of postoperative course and appearance, we observed 80.55% graft stability, 5.56% graft retraction, 2.78% graft displacement, and 11.11% graft loss. At the conclusion of follow-up, we noted an 8.33% recurrence rate. DISCUSSION: The use of intraoperative blood ensures patient safety and postoperative comfort. This technique demonstrates satisfactory results with primary, nasal pterygia. CONCLUSION: Conjunctival autograft without sutures or biological glue might be a very promising surgical alternative in the surgical treatment of pterygium.

[Ocular manifestations in patients with chronic renal insufficiency who are not dialysis: about 60 cases]. / Manifestations oculaires chez les patients insuffisants rénaux chroniques non dialyses : a propos de 60 cas.

OBJECTIVE: describe the ocular manifestations encounterd in chronic renal failure not on dialysis in order to ensure better management. METHODS: it is a descriptive analytical study, which took place from febrauary 2017 to june 2017. The study was carried out jointly in the Nephrology and Ophortamology departments of the Yopougon hospital and university center. It focused on patients with renal failure not on dialysis. A total of 60 patients were included with regard to the study inclusion criteria. RESULTS: patients personal history was dominated by high blood pressure arterial (88%) diabetes (27%). The decrease in visual acuity (BAV) and pruritus were symptoms at rates of 66.66% and 26% respectively. The review biomicroscopic anterior segment, has shown unilateral cataracts in 26.67% of cases. At the posterior pole, optic neuropathy was predominant (23,33%). The macular edemas were 10%. Arterial shrinkage (16.66%) was the most observed lesion of peripheral chorioretin. The hypertensive retinopathy (HR) and large papillary excavation (GEP) were the abnormalities most found on the back of the eye, each observing each in 43.75% of cases. We found no correlation between eye manifestations and IRC. CONCLUSION: There was no direct link between kidney failure and eye damage Observed. Several factors could explain the eye signs, including HTA and diabetes.

OBJECTIFS: décrire les manifestations oculaires rencontrées chez l'insuffisant rénal chronique non dialysé afin d'en assurer une meilleure prise en charge. MATÉRIEL ET MÉTHODES: il s'agit d'une étude descriptive et analytique, qui s'est déroulée du mois de février 2017 au mois de Juin 2017. L'étude a été menée conjointement dans les services de Néphrologie et d'Ophtalmologie du Centre Hospitalier et Universitaire (CHU) de Yopougon. Elle a porté sur les patients insuffisants rénaux non dialysés. Au total 60 patients ont été inclus eu égard aux critères d'inclusion de l'étude. RÉSULTATS: les antécédents personnels des patients étaient dominés par l'hypertension artérielle (88%) et le diabète (27%). Labaisse de l'acuité visuelle (BAV) et le prurit étaient lessymptômes plus exprimésà des taux respectifs de 66,66% et 26%. L'examen biomicroscopique du segment antérieur, a mis en évidence une cataracte unilatérale chez 26,67% des cas. Au pôle postérieur, les neuropathies optiques étaient prédominantes (23,33%). Les oedèmes maculaires étaient de 10%. Le rétrécissement artériel (16,66%) représentait la lésion la plus observée au niveau de la choriorétine périphérique. La rétinopathie hypertensive (RH) et la grande excavation papillaire (GEP) étaient les anomalies les plus retrouvées à l'examen du fond d'œil, s'observant chacune dans 43,75% des cas. Nous n'avons pas retrouvé de corrélation entre les manifestations oculaires et l'IRC. CONCLUSION: Il n'existait pas de lien direct entre l'insuffisance rénaleet les lésions oculaires observées. Plusieurs facteurs pourraient expliqués les signes oculaires, notamment l'HTA et le diabète.

[Comparison of Goldmann tonometry with air-puff tonometry. A study of 159 patients in Abidjan]. / Comparaison de la tonomérie de Goldmann à la tonométrie à air pulsé à propos de 159 patients à Abidjan.

PURPOSE: The goal of this study was to compare the intraocular pressure (IOP) values obtained with each of the tonometry methods as well as to study the effect of corneal pachymetry on the measurements obtained by each method. MATERIAL AND METHODS: We carried out a cross-sectional, descriptive, analytical, prospective study in the ophthalmology department of a multispecialty clinic in Abidjan (Ivory Coast) from April 2018 to August 2018. Patients aged 15 and over were included in the study. Over this period, IOP was measured by Goldman Applanation Tonometer (HaagStreit, AT 900, Switzerland) and air-puff Tonopachymeter (Nidek, NT 530 P, Japan), which also permitted measurement of central optical corneal pachymetry. The data analyzed focused on socio-demographic characteristics, ophthalmologic history, tonometry, and central corneal pachymetry. The comparison of the values obtained by both devices and the effect of central corneal thickness (CCT) on tonometry were analyzed using EpiDataAnalysis V2.2.2.183 software. RESULTS: We examined 318 eyes of 159 patients whose mean age was 40±12.57 years, range 16 to 82 years. The gender ratio was 1. A past ophthalmologic history was noted in 79.2% of patients. The mean IOP by Goldmann applanation tonometry was 12.75±3.17mmHg, and that by non-contact air-puff tonometry was 13.83±3.80mmHg. The mean central corneal thickness was 530.50±32.61µm. The difference between IOP measured by non-contact tonometry and that measured by contact tonometry was statistically significant, with P=0.00. There was no statistically significant relationship between central corneal pachymetry and contact tonometry (P=0.80). However, there was a statistically significant relationship between non-contact tonometry and central pachymetry (P=0.00). The values obtained with the air-puff tonometer are more affected by central corneal thickness. CONCLUSION: The values obtained by Goldmann applanation tonometry are not equivalent to those obtained by non-contact air-puff tonopachymetry.

[Investigation of urinary schistosomiasis outbreak in the primary school of the village Guébo 2, Abidjan, Côte d'Ivoire]. / Investigation d'un foyer épidémique de bilharziose urinaire dans l'école primaire du village de Guébo 2, Abidjan, Côte d'Ivoire.

We report the results of an outbreak investigation of urinary schistosomiasis in 2012 among school children at Guébo 2. Among the 250 school children, 107 (42.8%) had confirmed urinary schistosomiasis. Age ≥ 10y (OR = 2.6 [1.1 to 6.2]) and self-reported bathing in the river (OR = 14.0 [4.7 to 42.5]) were associated with the presence of S.h. in the adjusted analyses. A massive deworming of the population of Guébo-1&2 was conducted as epidemic-response.

[Central corneal thickness and potential error in Goldmann applanation tonometry of the Black African patient suffering from primary open-angle glaucoma: 340 eyes surveyed]. / Epaisseur cornéenne centrale et erreur potentielle de la tonométrie à aplanation de Goldmann chez le patient noir africain atteint de glaucome primitif à angle ouvert. A propos de 340 yeux.

INTRODUCTION: Goldmann applanation tonometry is the reference method for measuring IOP. This tonometric model is influenced by corneal thickness, which varies according to race. Most studies have been conducted on Caucasian or Black American subjects. Studies on Black African subjects being rare, the goal of our study was to measure the central corneal thickness and its impact on Goldmann applanation tonometry on Black African subjects suffering from primary open-angle glaucoma (POAG). PATIENTS AND METHODS: Our retrospective study focused on POAG eyes. The central corneal thickness was measured using an ultrasonic pachymeter (Quentel Médical). RESULTS: 340 eyes from 170 patients made up the sample. The mean age of our patients was 44.4 +/- 12.7 years, with a mean central corneal thickness of 519.6 +/- 32.6 microm. Of our patients, 57.6% had a central corneal thickness less than 527 microm, 30.6% between 527 and 560 microm, and 11.8% had a central corneal thickness greater than 560 microm. DISCUSSION AND CONCLUSION: Compared to Black American and Caucasian subjects, the Black African glaucoma subject differs in the early age of glaucoma onset and the thinness of the cornea. Corneal thickness evaluation induces a potential error in IOP measurement on Black African glaucoma subjects. On the Black African subject, Goldmann tonometry is therefore affected by an error rate estimated at 69.4% (57.6% underevaluation and 11.8% overevaluation). Pachymetry is therefore a necessity for the Black African glaucoma patient requiring IOP adjustment.
