This study examines the association between excessive digital media use and adverse health outcomes, specifically Digital Eye Strain (DES) and Poor Sleep Quality (PSQ), in adolescents. A cross-sectional survey of 512 participants (aged 11–18 years) assessed DES and PSQ using the Computer Vision Syndrome Questionnaire and the Pittsburgh Sleep Quality Index. We found a high prevalence of DES (63.7%) and PSQ (51.2%). Factors associated with DES included using digital media for more than two hours daily, increased post-pandemic digital consumption, shorter breaks, and PSQ. Extended daily digital media use (>4 hours), bedtime usage, older age, female sex, online education and DES were significantly associated with PSQ. These findings highlight the harmful effects of excessive digital media use on adolescent health, especially post-COVID-19. The intricate link between DES and PSQ underscores the need for public health interventions to promote healthy digital habits. [ABSTRACT FROM AUTHOR]

Introduction: Epilepsy is a network disorder that can cause alterations in retinal morphology due to microstructural changes in the brain. The aim of our study was to use spectral optical coherence tomography (OCT) to assess the possible effects of neuronal degeneration on the intraretinal layers and macular structures of people with epilepsy and epilepsy subgroups. Methods: We enrolled 52 consecutive people with epilepsy (37 females, 15 males; mean age 29.8±9.9 years; range, 17-48 years) and 40 healthy volunteers (27 females, 13 males; mean age 33.3±10.2 years; range, 19-49 years) in this study. Both eyes of all participants were assessed by using spectral-domain OCT. Optical coherence tomography was used to assess the thickness of the peripapillary retinal nerve fiber layer (RNFL), ganglion cell layer-inner plexiform layer (GCC-IPL), central macula, and central macular volume. Results: In comparison to healthy controls, people with epilepsy showed a thinner GCC-IPL in the superior and superior-nasal quadrants, as well as reduced macular thickness and macular volume (p<0.05). The thickness of the GCC-IPL layer in the superior and inferior subquadrants was negatively affected by frequent seizures (>5 seizures/year), polytherapy, and long-duration of epilepsy (≥10 years) (p<0.05). However, we did not find any other statistically significant associations between OCT measurements, age, sex, and epilepsy type (focal and generalized onset epilepsy). Conclusion: Individuals with epilepsy exhibited microstructural alterations in the retinal layers, primarily in the superior and inferior quadrants. Frequent seizures, polytherapy, and long-duration of epilepsy may result in neuronal damage in the afferent visual system. [ABSTRACT FROM AUTHOR]

Glaucoma is one of the most common causes of blindness. Although high intra-ocular pressure (IOP) is the most important risk factor, ocular blood flow also has an effect on prognosis. The aim of this study was to investigate the IOP, ocular pulse amplitude (OPA) and choroidal thickness (CT) changes after trabeculectomy and to determine whether trabeculectomy has an effect on ocular blood flow. This retrospective, comparative case series was conducted with 33 eyes of 33 patients who underwent trabeculectomy due to uncontrolled glaucoma. The fellow eyes of 20 patients who were followed up with medical therapy were included as a control group. IOP and OPA were evaluated using a dynamic contour tonometer. Subfoveal choroidal thickness (SFCT) was obtained with enhanced depth imaging (EDI) mode of Spectralis-OCT. The mean IOP was 21.6 ± 6.3 mmHg at baseline and 13.8 ± 0.9 mmHg after trabeculectomy (p ˂ 0.001), and the mean OPA was 4.1 ± 1.5 at baseline and 2.6 ± 1.6 mmHg after trabeculectomy (p ˂ 0.001). The mean SFCT was 292.2 ± 63.2 µm at baseline and 303.8 ± 70.4 µm after trabeculectomy (p = 0.024). The change in OPA was strongly positively correlated with the change in IOP (r = 0.597, p ˂ 0.001) and SFCT change was positively correlated with OPA change (r = 0.34, p = 0.05). There was no difference between the two groups in terms of IOP, OPA and SFCT values measured after trabeculectomy (respectively, p = 0.264, p = 0.627 and p = 0.949). The large IOP decrease following trabeculectomy causes a decrease in OPA and choroidal thickening. On the other hand, trabeculectomy has no effect on OPA change. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to evaluate and report the complication rates, and anatomical and functional outcomes of eyes undergoing inferior retinectomy for the management of recurrent rhegmatogenous retinal detachment (RRD) due to inferior proliferative vitreoretinopathy (PVR). Materials and Methods: This retrospective, non-comparative, interventional case series was conducted with 32 eyes of 32 patients with recurrent RRD due to inferior PVR who had previously undergone 23-gauge pars plana vitrectomy (PPV) and inferior retinectomy. Demographic data, and preoperative, intraoperative and postoperative characteristics were evaluated from the medical records of the patients. The anatomic and functional success were considered as the primary outcomes. The secondary outcome was the postoperative complications. Results: The mean follow-up time after the PPV with retinectomy was 10.6 ± 4.9 (min. 6, max. 24) months. After the initial retinectomy, anatomic success was achieved in 22 (68.7%) patients. Overall, the retinas of 27 patients (84.4%) were successfully reattached after retinectomy and PPV at the last visit. The mean best-corrected visual acuity (BCVA) improved from 1.72 ± 0.97 LogMar (range, 3.0-0.4 LogMar) to 1.20 ± 0.65 LogMar (range, 3.0-0.3 LogMar) at the final visit. There was a statistically significant increase in visual acuity postoperatively (p = .01). At the last visit, BCVA was improved in 19 eyes (59.4%), stabilized in 8 eyes (25%) and decreased in 5 eyes (15.6%). The most significant factor affecting the final BCVA was the baseline visual acuity (p = .002). Two patients (6.2%) developed hypotonia postoperatively. None of the cases presented with endophthalmitis, keratopathy or postoperative phthisis bulbi. Conclusion: Inferior retinectomy is effective in managing recurrent RRD cases due to inferior PVR and can increase functional success rates. [ABSTRACT FROM AUTHOR]

Purpose: To investigate macular thickness (MT), ganglion cell complex (GCC), and retinal nerve fiber layer (RNFL) thickness changes in preperimetric glaucoma patients. Materials and Methods: In the present study 105 eyes of 75 patients were investigated. Of these patients, 56 eyes of 45 patients who were diagnosed as preperimetric glaucoma are taken as a study group and 49 eyes of 30 cases without any ocular pathology are taken as the control group. The mean values of central MT, parafoveal MT, perifoveal MT, parafoveal GCC thickness, and perifoveal GCC thickness evaluations using optical coherence tomography (OCT) were compared between the two groups. Peripapillary RNFL measurements; the mean values of the total, superior hemi-central, inferior hemi-central, superior, inferior, nasal, and temporal quadrants, and twelve sectors were compared between the two groups. Results: In the study group, perifoveal GCC thickness was significantly thinner in the superonasal, superotemporal, inferonasal, and inferotemporal quadrants compared to the control group. Peripapillary RNFL thickness was significantly thinner in the study group in total, superior hemi-central, inferior hemi-central, superior, inferior, nasal, temporal, and hour 1,2,3,4,5,7,8,9 quadrants. No significant difference was detected between the two groups in other measurements (p>0.05). Conclusion: However both macular and peripapillary cellular losses have been initiated in cases with preperimetric glaucoma, this loss can not be detected by standard automated perimetry. As a result, perifoveal GCC and peripapillary RNFL measurements by OCT in patients with preperimetric glaucoma are very helpful for diagnosing suspicious cases. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy of intravitreal ranibizumab in exudative age-related macular degeneration (AMD) after a follow-up time of 24 months. Materials and Methods: The treatment-naive exudative AMD patients who initially received 3 consecutive monthly injections, and then were treated on an as-needed treatment regimen depending on clinical examination and optical coherence tomography findings were retrospectively evaluated. The patients were evaluated in regards of best corrected visual acuity (BCVA), central macular thickness (CMT), injection numbers, and complications. Results: A hundred and one eyes of 94 patients were included in the study. The mean age was 73.6±8.2 years (ranging between 53 and 89 years). Forty-five patients (47.9%) were male, and 49 patients (52.1%) were female. The mean pretreatment BCVA, the mean BVCA at month 12, and 24 was 0.90±0.51 LogMAR, 0.73±0.46 LogMAR (p<0.001) and 0.75±0.49 LogMAR (p<0.001), respectively. The mean pretreatment CMT, and the mean CMT at month 12, and month 24 was 331±98 microns, 259±66 microns (p<0.0001) and 262±70 microns (p<0.0001). The mean number of injections at month 12, and 24 was 5.3±1.5, and 8.0±3.0 injections, respectively. Conclusion: The intravitreal ranibizumab with an as needed treatment regimen seems to be effective in the treatment of exudative AMD over 24 months. [ABSTRACT FROM AUTHOR]

This study aims to determine the relationship between systemic inflammatory biomarkers and primary acquired nasolacrimal duct obstruction and to evaluate whether they can be used as indicators in determining the risk of recurrence after dacryocystorhinostomy. This retrospective, comparative case series was conducted with 57 primary acquired nasolacrimal duct obstruction patients and 58 age- and gender-matched controls. All subjects underwent a complete ophthalmologic examination and complete blood count measurements. The mean neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index were significantly higher in patients with primary acquired nasolacrimal duct obstruction (p = 0.005, p = 0.01, and p = 0.003, respectively). In recurrent patients, the neutrophil-to-lymphocyte ratio was significantly higher than in those who did not develop a recurrence (p = 0.029). The area under the curve was determined as 0.775 (p = 0.029) for the neutrophil-to-lymphocyte ratio in predicting recurrence. The neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index levels were significantly higher in patients with primary acquired nasolacrimal duct obstruction compared to healthy controls. The neutrophil-to-lymphocyte ratio might be used as a simple and inexpensive indicator for predicting recurrence in patients with primary acquired nasolacrimal duct obstruction., Competing Interests: The authors declare that they have no conflicting interests.
