ABSTRACT Our objective was to evaluate and describe the techniques and outcomes of limbal stem cell transplantation in patients with limbal stem cell deficiency after chemical burn of the ocular surface. We performed this literature review using the PubMed® (MEDLINE), Cochrane and Embase (Elsevier) databases. Of the 313 studies found, 276 were removed as duplicates and ineligible based on the inclusion and exclusion criteria; 17 articles remained after full reading, classified according to the criteria of interest, and 1 article […]

ABSTRACT Thygeson’s keratitis is a chronic bilateral inflammation of the cornea, characterized by recurrent intraepithelial opacities, intense photophobia, and visual fluctuations, especially in children. Topical corticosteroids are effective, but their prolonged use carries risks and frequent recurrences. We report the case of an 11-year-old girl with refractory Thygeson’s keratitis treated with topical tacrolimus 0.03%. After an initial response to corticosteroids, an early recurrence occurred within 15 days. With the introduction of tacrolimus, there was complete resolution of signs and symptoms, […]

ABSTRACT Objective: To evaluate the tomography accuracy of Cirrus 5000 optical controls in patients with or without keratoconus for pachymetry measurements by image scanning patterns. Methods: A prospective, cross-sectional and mixed study was performed in 20 eyes, where 37 parameters of each sample was analyzed and repeated 5 times. Results: Only four samples (vertex full, maximum epithelial pachymetry at 5 to 7.0mm, maximum epithelial pachymetry at 7 to 9.0mm and epithelial pachymetry difference between minimum and average) samples showed a […]

Measles is a contagious disease caused by morbillivirus, a virus of the family paramyxoviridae.() It evolves through four phases: incubation, invasion, eruption and desquamation. Ophthalmologic manifestations are rare. They may occur during the invasive and eruptive phases.() Measles keratitis is the most concerning manifestation; it may vary from simple superficial punctate keratitis to corneal perforation. We report a case of acute keratitis occurring during the eruptive phase of measles in an unvaccinated adult during an epidemic. […]

ABSTRACT Objective: To evaluate the clinical and surgical results of patients undergoing corneal endothelial transplant surgery. Methods: Retrospective study in which medical records were reviewed from May 2016 to May 2023, to evaluate transplant indications, intra- and postoperative complications and survival of the graft. Results: Seventeen patients were included, 12 (70.6%) were female and the average age was 70.18. The main indication for corneal endothelial transplant surgery was pseudophakic bullous keratopathy (64.7%), followed by Fuchs dystrophy (23.5%). Regarding postoperative visual […]

ABSTRACT Objective: To assess the impact of the COVID-19 pandemic on corneal donations and the operation of the eye bank in the Zona da Mata Mineira Region. Methods: Retrospective analysis of medical records of all donations obtained by the Banco de Olhos Hospital Regional Dr. João Penido/FHEMIG, Juiz de Fora – MG between 2017 and 2022, comparing pre (January/2017 – March 11/2020) and post-pandemic (12/March/2020 – December/2022) periods. Results: There was a reduction in cornea donations and the number of […]

ABSTRACT LASIK is a refractive surgical procedure in which a corneal flap is created to expose the corneal stromal bed. Preoperative estimation of corneal flap thickness is necessary to calculate the percentage tissue altered in LASIK, an important quantitative risk factor for ectasia. The objective of this study was to assess flap thickness and calculate percentage tissue altered to check if unexpectedly thicker flaps and higher percentage tissue altered could pose as risk factors of ectasia. Four subjects (eight eyes) […]

ABSTRACT Objective To identify higher order aberrometry changes in different degrees of keratoconus. Methods Cross-sectional, retrospective, observational study. Fifty-four patients (108 eyes) diagnosed with keratoconus by the same corneal specialist using the Belin/Ambrósio Enhanced Ectasia ABCD criteria were analyzed, using the Pentacam® HR 70900 tomograph (Oculus Wetzlar, Germany). In addition, qualitative and quantitative analysis of higher order aberrations in these patients was performed using the OPD-Scan III-NIDEK. Results Through the evaluation of both eyes of the patients according to the […]
