[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.

[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.
