There are currently multiple technologies for DR detection, some of which are already commercially available. To understand how these technologies work, we must know first some basic concepts about artificial intelligence (AI) such as machine learning (ML) and deep learning (DL). ML is the basic process by which AI incorporates new data using different algorithms and thus creates new knowledge on its base, learns from it, and makes determinations and predictions on some subject based on all that information. AI can be presented at various levels. DL is a specific type of ML, which trains a computer to perform tasks as humans do, such as speech recognition, image identification, or making predictions. DL has shown promising diagnostic performance in image recognition, being widely adopted in many domains, including medicine. For general image analysis, it has achieved strong results in various medical specialties such as radiology dermatology and in particular for ophthalmology. We will review how this technology is constantly evolving which are the available systems and their task in real world as well as the several challenges, such as medicolegal implications, ethics, and clinical deployment model needed to accelerate the translation of these new algorithms technologies into the global health-care environment.","PeriodicalId":437914,"journal":{"name":"Latin American Journal of Ophthalmology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126320105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the changing scenario of health-care delivery, ophthalmologists had to bring about several changes in the way, the patients are seen and operated on. Contact procedures were entirely restricted to emergencies while modifications were introduced to minimize the exposure of the surgeon. However, these modifications were introduced just keeping in mind the spread of infection. The probability that these modifications could affect the optics in ophthalmology is high and cannot be ruled out. The aim of the study was to highlight the effects of modifications introduced in ophthalmic equipment during the pandemic over the visibility for the surgeon and discuss its impact on patient care in ophthalmology. Thorough search of the literature on PubMed using keywords, visibility and personal protective equipment (PPE), fogging and PPE, face mask and fogging, aberrations and PPE, and surgeries and PPE were done. We found 35 articles which highlighted the effects on visibility with PPE and effects on eyes with prolonged wearing of masks. Several factors have contributed to reduction in visibility for the surgeon. These factors have, in turn, affected the overall quality of examination and surgical outcome in ophthalmology. The use of PPE during the pandemic could have been a contributory factor for missing relevant findings during examination of patients. For ophthalmologists in particular, the visibility and optics play a crucial role in the management of the patient and have been invariable affected by introduction of modifications at the instrument and surgeon level.","PeriodicalId":437914,"journal":{"name":"Latin American Journal of Ophthalmology","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122874556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the long-term outcomes in eyes treated for varying degrees of GRT-associated RRD extensions and compared them with two control groups. Twenty-five emmetropic normal eyes (control emmetropic), 20 healthy myopic eyes (control myopic), and 33 eyes surgically treated for GRT (surgical) were included in this study for a comparison of long-term structural, perfusional, and functional outcomes. The surgical eyes were categorized based on degree of GRT-associated RRD extension: 19 eyes with GRT-associated RRD extension <180° and 14 eyes with extension >180°. The eyes were further separated by whether they required placement of a complementary 360° scleral buckle. The mean age of the patients was 55.18 years and the mean pre-operative evolution of GRT was 2.36 weeks. The average pre- and post-operative best-corrected visual acuities (BCVAs) were 1.90 logMAR and 0.59 logMAR, respectively, which were different with statistical significance. Proliferative vitreoretinopathy resulted in multiple surgeries in nine eyes (27.3%). Long-term post-operative optical coherence tomography (OCT) showed 11 eyes (33.3%) with abnormal foveal contour, 13 eyes (39.4%) with ellipsoid zone disruption, two eyes with dissociated optic nerve fiber layer defects, and 15 eyes (45.4%) with external limiting membrane line discontinuities. OCT angiography yielded abnormal perfusion indices in the surgically treated eyes (P < 0.0001). Correlation analysis found that post-surgical BCVA was negatively correlated with superficial foveal avascular zone area, superficial parafoveal vessel density, and central subfoveal thickness, while positively correlated with choriocapillaris flow area. Our data showed that eyes with GRT-associated RRD have multiple structural alterations in spectral-domain OCT biomarkers that are correlated with visual outcomes. Despite successful retina reattachment without proliferation, management of GRT-associated RRD remains challenging.","PeriodicalId":437914,"journal":{"name":"Latin American Journal of Ophthalmology","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121567986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The group of patients studied consisted of 9 patients (47.36%) female and 10 patients (52.64%) male, the age range was 14–68 years. All cases were ophthalmologically evaluated, including best-corrected visual acuity, anterior and posterior segment biomicroscopy, intraocular pressure, binocular indirect ophthalmoscopy, and as additional complementary examinations, ocular ultrasound was performed, which in 100% of the cases was inconclusive, optical coherence tomography, autofluorescence, and angiography in selected cases according to location and symptomatology. In 13 patients (68.50%), transvitreous puncture was performed with or without vitrectomy. Trans-scleral puncture was performed in 6 patients (31.50%), located at the equator (4 patients) and ciliary body (2 patients). Post-surgical follow-up was performed within the first 3 weeks after the procedure and then controlled every 3 months within the 1st year.
