Special Issue Information

Dear Colleagues,

Despite continuous improvements in diagnosis and therapy, blindness and visual impairment are still significant challenges in healthcare systems, in the context of increasing population and aging globally. Cataract, glaucoma, age-related macular degeneration, and uncorrected refraction errors are listed among the top causes of visual impairment worldwide. In recent years, there have been significant achievements regarding ophthalmic imaging and development of surgical techniques and devices. In the era of artificial intelligence and telemedicine, new techniques were designed to improve screening and monitoring of chronic ophthalmic diseases.

In this Special Issue, we would like to invite you to submit papers (original research and reviews) thematically connected to the scope of this Special Issue. We are particularly, but not exclusively, interested in papers focused on the recent development in diagnosis and therapy of ophthalmic diseases, management of postoperative complications, new biomarkers of diagnosis and monitoring, the impact of COVID-19 pandemic on the ocular diseases, and the use of artificial intelligence-based models in ophthalmology.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Medicina is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Background and Objectives: Glaucoma (GL) classification is crucial for early diagnosis and treatment, yet relying solely on stand-alone models or International Classification of Diseases (ICD) codes is insufficient due to limited predictive power and inconsistencies in clinical labeling. This study aims to improve GL classification using stacked weight-based machine learning models. Materials and Methods: We analyzed a subset of 33,636 participants (58% female) with 340,444 visual fields (VFs) from the Mass Eye and Ear (MEE) dataset. Five clinically relevant GL detection models (LoGTS, UKGTS, Kang, HAP2_part1, and Foster) were selected to serve as base models. Two multi-layer perceptron (MLP) models were trained using 52 total deviation (TD) and pattern deviation (PD) values from Humphrey field analyzer (HFA) 24-2 VF tests, along with four clinical variables (age, gender, follow-up time, and race) to extract model weights. These weights were then utilized to train three meta-learners, including logistic regression (LR), extreme gradient boosting (XGB), and MLP, to classify cases as GL or non-GL. Results: The MLP meta-learner achieved the highest performance, with an accuracy of 96.43%, an F-score of 96.01%, and an AUC of 97.96%, while also demonstrating the lowest prediction uncertainty (0.08 ± 0.13). XGB followed with 92.86% accuracy, a 92.31% F-score, and a 96.10% AUC. LR had the lowest performance, with 89.29% accuracy, an 86.96% F-score, and a 94.81% AUC, as well as the highest uncertainty (0.58 ± 0.07). Permutation importance analysis revealed that the superior temporal sector was the most influential VF feature, with importance scores of 0.08 in Kang’s and 0.04 in HAP2_part1 models. Among clinical variables, age was the strongest contributor (score = 0.3). Conclusions: The meta-learner outperformed stand-alone models in GL classification, achieving an accuracy improvement of 8.92% over the best-performing stand-alone model (LoGTS with 87.51%), offering a valuable tool for automated glaucoma detection.

Marfan syndrome (MFS) is a genetic disorder that affects the connective tissue in several systems, with ocular, cardiovascular, and skeletal system manifestations. Its ocular manifestations include ectopia lentis (EL), myopia, astigmatism, and corneal abnormalities. This review examines refractive alterations related to MFS such as EL, microspherophakia, lens coloboma, altered corneal biomechanics (flattening, thinning, and astigmatism), and myopia and their impact on visual acuity. The pathogenesis of these manifestations stems from mutations in the FBN1 gene (encoding fibrillin-1). Moreover, the current medical and surgical management strategies for MFS-related refractive errors, including optical correction (eyeglasses, contact lenses, etc.), and surgical interventions like lensectomy, intraocular lens (IOL) implantation (anterior chamber, posterior chamber, scleral-fixated, iris-fixated), and the use of capsular tension rings/segments are further discussed. Considering the likelihood of underdiagnosing and underestimating ocular involvement in MFS, this updated review highlights the critical need to identify and address these refractive issues to enhance the visual outcomes for those affected.
