Comparison of surgical outcomes of Carlevale sutureless scleral fixation and Artisan Aphakia intraocular lens.

PURPOSE: To compare intra- and postoperative results of sutureless scleral fixated Carlevale intraocular lens (IOL) with iris fixated Artisan IOL. METHODS: Monocentre, retrospective analysis of refractive outcomes and intra- and postoperative complications of patients who received a Carlevale or Artisan IOL between January 2019 and March 2022. RESULTS: 178 eyes of 169 patients were included (101 Carlevale and 77 Artisan IOLs). The standard follow-up time was 1 month. Two statistically significant differences were found: in the deviation of the postoperative spherical equivalent of the refraction from the preoperative chosen IOL target (p = 0.019; mean deviation was -0.46 in the Carlevale and 0.08 in the Artisan group), and the number of eyes with complications between the Carlevale and Artisan groups (p = 0.003; 33 in the Carlevale and 42 in the Artisan group). CONCLUSION: The current study is the largest so far comparing both refractive outcomes and complications after implantation of Carlevale and Artisan IOL. The Carlevale IOL does not carry a greater complication risk on the short-term follow-up. This provides additional evidence that the Carlevale IOL has to be added to the armamentarium of the ophthalmic surgeon.

Exploring the choroidal vascular labyrinth and its molecular and structural roles in health and disease.

The choroid is a key player in maintaining ocular homeostasis and plays a role in a variety of chorioretinal diseases, many of which are poorly understood. Recent advances in the field of single-cell RNA sequencing have yielded valuable insights into the properties of choroidal endothelial cells (CECs). Here, we review the role of the choroid in various physiological and pathophysiological mechanisms, focusing on the role of CECs. We also discuss new insights regarding the phenotypic properties of CECs, CEC subpopulations, and the value of measuring transcriptomics in primary CEC cultures derived from post-mortem eyes. In addition, we discuss key phenotypic, structural, and functional differences that distinguish CECs from other endothelial cells such as retinal vascular endothelial cells. Understanding the specific clinical and molecular properties of the choroid will shed new light on the pathogenesis of the broad clinical range of chorioretinal diseases such as age-related macular degeneration, central serous chorioretinopathy and other diseases within the pachychoroid spectrum, uveitis, and diabetic choroidopathy. Although our knowledge is still relatively limited with respect to the clinical features and molecular pathways that underlie these chorioretinal diseases, we summarise new approaches and discuss future directions for gaining new insights into these sight-threatening diseases and highlight new therapeutic strategies such as pluripotent stem cell‒based technologies and gene therapy.

Behçet's disease, hospital-based prevalence and manifestations in the Rotterdam area.

INTRODUCTION: Behçet's disease is most prevalent in countries along the former Silk Road. Prevalence varies from 70-420 per 100,000 in Turkey, and 13.5-20 and 1-2 per 100,000 in Asia and Western Europe, respectively. Additionally, disease severity and morbidity might be correlated with ethnicity. We studied demography and morbidity in the Dutch cohort of patients with Behçet's disease and compared those with known figures. PATIENTS AND METHODS: The prevalence of Behçet's patients in the Rotterdam area was determined by comparing the total number of patients within the ethnic population with the number of patients diagnosed with Behçet's disease. Patient files of the Erasmus University Medical Centre (Erasmus MC) were reviewed for morbidity figures and compared with existing data. RESULTS: In total 84 Behçet's patients of Dutch, Turkish or Moroccan descent were identified in the Rotterdam area. Prevalence of Behçet's disease differed per ethnicity: 1, 71 and 39 per 100,000 for Dutch-Caucasians, Turks, and Moroccans, respectively. These figures are comparable with occurrence in West Turkey and Morocco. Within the studied Erasmus MC cohort no significant differences in morbidity appeared between the ethnic groups. However, uveitis and pustules were significantly more common in the Erasmus MC cohort as compared with UK, German, Turkish and Moroccan cohorts. DISCUSSION AND CONCLUSIONS: We present the first epidemiological study of Behçet's disease in the Netherlands. The prevalence of Behçet's disease in the studied Dutch region and in countries of ancestry is similar. Morbidity is equally spread, compared with other countries, but uveitis and pustules seem to be more common in the Netherlands.
