AIMTo compare the visual outcomes (distance and near) in patients opting for three different types of monofocal intraocular lens (IOL) (Matrix Aurium, AcrySof single piece, and AcrySof IQ lens).METHODSThe present study is a cross-sectional analysis of secondary clinical data collected from 153 eyes (52 eyes in Matrix Aurium, 48 in AcrySof single piece, and 53 in AcrySof IQ group) undergoing cataract surgery (2011-2012). We compared near vision, distance vision, distance corrected near vision in these three types of lenses on day 15 (±3) *** 69% of the eyes in the Matrix Aurium group had good uncorrected distance vision post-surgery; the proportion was 48% and 57% in the AcrySof single piece and AcrySof IQ group (P=0.09). The proportion of eyes with good distance corrected near vision were 38%, 33%, and 15% in the Matrix Aurium, AcrySof single piece, and AcrySof IQ groups respectively (P=0.02). Similarly, The proportion with good “both near and distance vision” were 38%, 33%, and 15% in the Matrix Aurium, AcrySof single piece, and AcrySof IQ groups respectively (P=0.02). It was only the Matrix Aurium group which had significantly better both “distance and near vision” compared with the AcrySof IQ group (odds ratio: 5.87, 95% confidence intervals: 1.68 to 20.56).CONCLUSIONMatrix Aurium monofocal lenses may be a good option for those patients who desire to have a good near as well as distance vision post-surgery.

Introduction: Ametropias or refractive errors are pathologies commonly encountered in ophthalmology characterized by the projection on the retina of a blurry image. There are several types of ametropia and each of them has a specific means of correction. In the literature, numerous data have been reported on the issue through studies that were mostly carried out on infant populations. To better treat ametropia in a more formal way, it is important to know their general characteristics within a larger population, hence the present investigation, the aim of which is to carry out an epidemiological study of ametropia at the Kati University Hospital-BSS. Materials and Methods: The study was carried out at Kati University Hospital-BSS between January 1 and December 31, 2022 and included 663 ametropic patients of all ages. Results: During the study period, 663 cases of ametropia were diagnosed out of 1678 new consultations, representing an incidence of 39.51%. Patients aged between 21 and 40 years were more affected. Depending on the type, these ametropias were dominated by compound astigmatism with 68.75% followed by isolated hyperopia and isolated astigmatism. Visual fatigue was the most mentioned reason for consultation. The female gender was in the majority with 70.9%. Low ametropia (Discussion: The growing visual needs of young people, especially with new information and communication technologies, would push them to consult the ophthalmologist more, and therefore to want optical correction in the event of a refractive anomaly, which would partly explain their high frequency in this age group. Conclusion: It is important to know the general characteristics of ametropia in the general population in order to improve the quality of life of patients affected by it through efficient therapeutic solutions.

AIM: To study ocular axial lengths in pediatric subjects without intraocular pathology. METHODS: An Institutional Review Board-approved consecutive retrospective chart review of axial lengths measured in pediatric subjects who underwent examination under anesthesia due to positive family history of retinoblastoma or other inherited ocular disease. Only subjects without any intraocular pathology in either eye were included. Subjects were stratified into age groups. An axial length model using a logarithmic regression algorithm was ***: Data from 330 eyes of 165 subjects were included in the study. The mean age at the time of examination was 30.62(SD 18.04)mo. The steepest increase in axial length was present during the first 10 mo of life. After 36 mo, there was no statistically significant axial length growth. CONCLUSION: This study presents the biggest series of pediatric axial lengths in healthy eyes. The axial length model developed with these data may assist in the diagnosis and management of a wide variety of pediatric ophthalmic diseases.

Diabetes has become the epidemic of the 21 st century, and with over 90% patients with diabetes becoming at a risk of developing retinopathy, diabetic retinopathy has emerged as a major public health concern. In spite of cutting edge research in the field, how retina and its vasculature are damaged by the diabetic milieu remains ambiguous. The environmental factors, life style or disease process can also bring in modifications in the DNA, and these epigenetic modifications either silence or activate a gene without altering the DNA sequence. Diabetic environment up- or downregulates a number of genes in the retina, and emerging research has shown that it also facilitates epigenetic modifications. In the pathogenesis of diabetic retinopathy, the genes associated with important enzymes(e.g., mitochondrial superoxide dismutase, matrix metalloproteinase-9 and thioredoxin interacting protein) and transcriptional factors are epigenetically modified, the enzymes responsible for these epigenetic modifications are either activated or inhibited, and the levels of micro RNAs are altered. With epigenetic modifications taking an important place in diabetic retinopathy, it is now becoming critical to evaluate these modifications, and understand their impact on this slow progressing blinding disease.
