To show donation data, number of keratoplasties and the changes in transplant indications and techniques that occurred in Andalusia in the period from 2013 to 2022.

Materials and methods

The present work is a retrospective and descriptive study that included all keratoplasties performed between January 2013 and December 2022 in Andalusia, as well as the evolution of the cornea donation and transplant activity of the public and private hospitals pertaining to the waiting list management system of the Public Health System of Andalusia. Transplants performed in private centers with corneas from outside Andalusia were excluded.

Results

Cornea donation activity in Andalusia in the decade 2013−2022 has experienced a growth of more than 126%, while overall transplant activity has increased by 157% in public hospitals. Penetrating keratoplasty has decreased from 83% in 2013 to 43% in 2022, while lamellar techniques have increased from 17% to 57% in this same period. Since 2018, more lamellar transplants are performed than penetrating transplants. Regarding indications, endothelial conditions already represent the first cause of transplantation. In 2022 alone, the public Andalusian Eye Banks evaluated 1,054 corneas and prepared 281 endothelial grafts.

Conclusion

In the decade from 2013 to 2022 in Andalusia there has been an increase in donation activity and the number of keratoplasties. The public Eye Banks implementation in this period has played a key role in the widespread adoption of lamellar keratoplasty techniques and has enabled the transition to perform a greater number of lamellar keratoplasties compared to penetrating keratoplasty.

In retinopathy of prematurity (ROP) type I, the use of intravitreal bevacizumab (IVB), which is an inhibitor of endothelial growth factor (VEGF), has become popular despite not being a therapy approved by regulatory agencies. However, IVB has shown positive effects in halting disease progression at lower costs compared to other anti-VEGF therapies (ranibizumab or aflibercept). In this report, we present the experience during the treatment with IVB of 102 Colombian children with ROP type I, with a success rate of 98% (100). Complications occurred in 3.9% (4). Finally, we conclude that a single dose of IVB is an effective therapy for the management of ROP type I, with a lower risk of complications and retreatment.

Introduction

A survey conducted by the European Board of Ophthalmology (EBO) revealed significant differences in the surgical training of the ophthalmology residents in Europe, including a disparity between the sexes and a variation in the experience on cataract surgery (CC) between them. This study is about the Spanish sub-cohort of the survey, and its objective is to present and analyse the peculiarities of ophthalmology training in Spain within the European context, as well as discussing ways to harmonise and improve that training throughout the EU.

Methods

We analyse data of the Spanish participants in the EBO exams, defining subgroups by the Autonomous Communities existing in Spain.

Results

93 of 135 requested participants (68.9%) responded. A 60.2% passed the EBO exam between 2021 and 2022, being mostly women (65.59%) aged 31 years old on average. The 91.4% were right-handed, coming from 13 of the 17 Spanish autonomous communities, although mostly from the Community of Valencia, Madrid and Catalonia. Respectively, 16.1%, 3.2% and 8.7% of the respondents said they have completed 10 or more training sessions on animal eyes, synthetic eyes and through the virtual reality simulator. This training was correlated with greater self-confidence in the management of a posterior capsular tear during surgery (p .025). All respondents manifested to have already performed stages of the CC. The average number of operations reported was 181.6 with regional disparities. A significant difference is observed between the sexes against women (−28.3%, p 0.03).

Discussion

Ophthalmologists in Spain, much more than other European countries, have greater opportunities for surgical training, with surgical procedures during the residency, that nearly triples those made by the others. Spanish women refer, like their European colleagues, to be in disadvantage in learning opportunities about cataract surgery. The Simulation Based Medical Education (SBME) allows to respond to the training deficit and complements the training on the patient. Although we demonstrate a significant correlation between the number of procedures carried out and self-confidence to operate simple cases, the SBME would be a complementary tool in self-confidence in front of a complication like capsular rupture.

Conclusion

Spain massively adopts the model named by us "surgery for all”, despite the underrepresentation of women in this area, emphasising a need for cultural change that the SBME could facilitate.

Langerhans cell histiocytosis (LCH) is a myeloid neoplasm characterized by clonal neoplastic proliferation of Langerhans-type dendritic cells associated with an inflammatory infiltrate predominantly composed of lymphocytes and eosinophils. In this article, we present an unusual case of LCH with significant swelling in the left lacrimal sac region in a 3-year-old child, clinically mimicking acute dacryocystitis. Microscopically, it showed intense inflammatory infiltrate and histiocytes with irregular nuclei. The tumor cells were positive for S-100 protein, CD1a, and CD207 (langerin). Molecular study was positive for the V600E/E2/D mutation (EXON 15). This case emphasizes the importance of careful clinical, radiographic, and microscopic evaluation, as some neoplasms may mimic common benign lesions.

We describe a 28-year-old Caucasian female with vigorexy, who had no previous ocular history. She presented with bilateral gradual painless reduction in vision over the past 3 weeks. She had been taking niacin supplements, averaging 500 mg daily, for 7 years. Fundus examination revealed bilateral CME, which was confirmed by ocular coherence tomography scan. Fundus fluorescein angiography did not reveal any fluid leakage. Niacin supplementation was discontinued, and after 2 months, the CME had completely resolved, and the best corrected visual acuities improved to 1 in both eyes.
