Objective: Congenital nasolacrimal duct obstruction (CNLDO) is a common lacrimal system anomaly in newborns and infants. We aimed to evaluate the role of inflammation in the pathogenesis of persistent CNLDO and its potential use in diagnosis and follow up, focusing on novel inflammatory biomarkers: Systemic Immune-Inflammation Index (SII), Neutrophil-to-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR), Red cell distribution width (RDW), and Mean platelet volume (MPV).
Methods: A retrospective case-control study involving 76 CNLDO patients and 47 age-matched healthy controls was conducted. Complete blood count parameters were analyzed to calculate SII, NLR, PLR, RDW, and MPV. Receiver Operating Characteristic (ROC) analysis determined the diagnostic efficacy of these markers.
Results: SII, RDW, and neutrophil count were significantly elevated in the CNLDO group (p < 0.05). An elevated SII (cutoff > 200.9) demonstrated a sensitivity of 63.2% and a specificity of 63.8%. ROC analysis (AUC = 61.7%, p = 0.029) indicated that SII is a more significant marker for diagnosing CNLDO compared to NLR and PLR.
Conclusion: Elevated SII, indicative of systemic inflammation may serve as a significant biomarker in the diagnosis of CNLDO that does not resolve spontaneously and requires probing. SII > 200.9 acts as a threshold that aids in the diagnosis of persistent CNLDO. Being a valuable biomarker, SII can be used in monitoring patients with CNLDO and in identifying those who will require advanced treatment like probing. Prospective studies are essential to validate these findings.

Objectives: To investigate the clinical and image characteristics of primary systemic vasculitis-associated optic neuritis patients.
Methods: This is a retrospective study. The patients clinically diagnosed with primary system vasculitis-induced optic neuritis were recruited from March 2013 to December 2023. All cases received orbital magnetic resonance imaging scans were analyzed. The ocular findings, systemic manifestations, laboratory data and prognosis were reviewed retrospectively. In addition, the related literature was reviewed.
Results: Fourteen patients (21 eyes), including 10 men and 4 women, were enrolled in this study. The ages ranged from 30 to 86 years in this cohort. Orbits MRI detects the enlargement and/or enhancement of the optic nerve. Cases 1-5 reported a confirmed diagnosis of Takayasu's arteritis, and cases 6-8 had giant cell arteritis. Cases 9-13 were antineutrophil cytoplasmic antibody-associated vasculitis. Case 14 was Cogan's syndrome. Mult organs and tissues, such as the kidneys, heart, paranasal sinuses, meninges, and respiratory system, were involved. In all of the 14 involved patients, the disease onset was either during the fall or winter season. There were no or only slight improvements in visual activity after conventional therapies.
Conclusions: The autoantibodies' attack on the optic nerve, ischemic damage, or destruction of the blood-brain barrier may be the potential pathogenesis of vasculitis-associated optic neuritis. Even with prompt and aggressive clinical interventions, the prognosis remains unsatisfactory.

Purpose: To evaluate the effect of subtenon platelet-rich plasma (PRP) treatment in retinitis pigmentosa (RP) patients and to determine the factors affecting the response to treatment.
Methods: For this purpose, 85 eyes of 43 RP patients with visual acuity of 1 logMAR and above were included in the study and subtenon autologous PRP treatment was applied 3 times at two-week intervals. In addition to a full ophthalmological examination, functional tests such as visual acuity, visual field, central retinal sensitivity measurement, and electroretinography (ERG) and structural measurements including the thickness of the outer retinal layers, and the length of the ellipsoid zone in optic coherence tomography, and the dimensions of the hyperautofluorescent ring in fundus autofluorescence imaging (FAF) were performed on the patients before and one month after the treatment.
Results: A statistically significant improvement was achieved in the patient's visual acuity, visual field MD and PSD index, and dark-adapted 10.0 ERG response b wave amplitude. There was no significant change in average central retinal sensitivity, fixation stability, outer retinal layer thickness and ellipsoid zone length. No statistically significant change was detected in the diameter and area of the hyperautofluorescence ring measured by FAF. It was found that the age of the patients and the age of onset of the disease were parameters affecting the treatment response.
Conclusion: With PRP treatment applied periodically in RP patients, it may be possible to improve visual function and stop the progression of the disease, which can be detected by structural evaluations.

Purpose: To evaluate the changes in corneal biomechanical properties and tear film layer analysis after upper eyelid blepharoplasty surgery.
Method: Sixty eyes of 30 patients were included in our prospective study. Corneal hysteresis (CH), corneal resistance factor (CRF), corneal compensated intraocular pressure (IOPcc) and Goldmann intraocular pressure (IOPg) measurements were taken with the Ocular Response Analyzer (ORA) device at the preoperative, postoperative 1st and 3rd months. The ocular surface was evaluated with tear breakup time (TBUT) and Ocular Surface Disease Index (OSDI) scores. Lid crease (LC), margin-to-reflex distance 1 (MRD1), and palpebral fissure height (PFH) were evaluated at each visit.
Results: In the ORA analysis, in the 1st month CH value was found to be significantly lower than the preoperative value (preoperative 13.39 ± 6.08 mmHg; 1st month 10.74 ± 1.94 mmHg, p = 0.011). In addition, there was a statistically significant decrease in the 3rd month value compared to the preoperative values (10.46 ± 1.69 mmHg, p = 0.021). However CRF decreased postoperatively, no statistical difference was detected (preop 12.59 ± 3.84; 1st month 11.94 ± 3.04; 3rd month 9.78 ± 1.74; p = 0.149). While there was a decrease in IOPcc and IOPg in the postoperative period, no statistical difference was detected (respectively p = 0.96, p = 0.71). In the postoperative 1st month, TBUT increased significantly (p = 0.024). When those with a TBUT value below 10 were considered dry eye, significant decrease was observed in the percentage of dry eye in the first postoperative month (p = 0.027). Although the dry eye percentage decreased in the 3rd month compared to the preoperative percentage, no statistical difference was detected (p = 0.125). There was a significant decrease in the number of those with an OSDI score above 13 in the first month (p = 0.004).
Conclusion: In our study, a decrease in ORA values was observed after blepharoplasty, with only CH being statistically significant. Reducing the load on the cornea after surgery may change the corneal biomechanics. These changes should be taken into consideration after eyelid surgery, especially in patients who may require glaucoma follow-ups.

Objective: This study aims to investigate the morphological and histological characteristics of three-dimensional cell spheroids derived from the uveal melanoma (UM) cell line C918 and assess the impact of luteolin on their cell viability.
Methods: C918 cells were cultured in ultra-low adsorption 96-well plates, and morphological changes in C918 three-dimensional cell spheroids were observed over varying time intervals. Histological features of C918 multicellular spheroids cultured in ultra-low adsorption 6-well plates were examined using both HE staining and immunohistochemical staining. The CCK8 reagent was employed to measure the optical density at a 450 nm wavelength after 72-h treatments with varying luteolin concentrations in both two-dimensional and three-dimensional cultured C918 cells. The IC50 values were compared between the two culture conditions.
Results: Over time in culture, the volume of C918 three-dimensional cell spheroids gradually increased, and an ischemic- and hypoxic-like region became evident within the spheroids on days 4 to 6 of culture. Histological staining demonstrated positive expression of cell viability marker antibodies (Ki67) and melanoma marker antibodies (MelanA, HMB45, S-100) in the multicellular spheroids from three-dimensional culture. CCK-8 experiments revealed that the IC50 values for luteolin in C918 cells were 183.50 μmol/L in three-dimensional culture and 16.19 μmol/L in two-dimensional culture after 72 h. Three-dimensional cultured C918 cells, treated with varying luteolin concentrations for 72 h, were observed under a microscope. The maximum cross-sectional area showed no statistically significant differences between the groups, but it was reduced in comparison to the control group.
Conclusion: Three-dimensional cultured C918 cell spheroids exhibit histological characteristics similar to real tumors and are less responsive to luteolin than their two-dimensional counterparts. They offer a valuable model for anti-tumor drug screening.

Purpose: To present a clinically based approach to the differentiation of optic disc edema (DE) cases, commonly seen in neuro-ophthalmology.
Methods: Consecutive patients who were considered to have unilateral or bilateral DE during examinations in the outpatient clinic and were referred to the neuro-ophthalmology department were included in this prospective study. The examination findings and differential diagnosis based on clinical signs and symptoms, and neuro-ophthalmological approach were evaluated in cases of DE.
Results: Of the 119 cases with DE, 69 (58%) were women and 50 (42%) were men, where 89 (75%) had true optic DE (ODE) and 30 (25%) had pseudo optic DE (PODE). Non-arteritic anterior ischemic optic neuropathy (n = 40), increased intracranial pressure (n = 32), and anterior optic neuritis (n = 17) were determined as the causes of true ODE, whereas small and crowded optic disc (n = 12), tilted optic disc (n = 8), myelinated nerve fibers (n = 5) and optic disc drusen (n = 5) as the causes of PODE. Patients with optic neuritis were the youngest (28.41 years) group of ODE cases while those with non-arteritic anterior ischemic optic neuropathy were the oldest (59.98 years). The first symptoms were sudden and painless loss of vision and/or visual field in cases with non-arteritic anterior ischemic optic neuropathy, pain increasing with eye movements and loss of vision and/or visual field in cases with optic neuritis, headache, and from time to time blurred vision in cases with increased intracranial pressure. Patients having vision loss due to amblyopia constituted (30%) of PODE cases while 70% were determined incidentally and they had the best visual acuity. The accuracy of the preliminary diagnosis based on neuro-ophthalmologic examination findings was 79% in all cases.
Conclusion: Detailed history taking and neuro-ophthalmological examination are essential in the differential diagnosis of ODE and PODE.
目的:介绍神经眼科常见的视盘水肿(DE)病例的临床鉴别方法:方法:将在门诊检查中被认为患有单侧或双侧 DE 并转诊至神经眼科的连续患者纳入这项前瞻性研究。对 DE 病例的检查结果、基于临床症状和体征的鉴别诊断以及神经眼科方法进行了评估:在 119 例 DE 患者中,69 例(58%)为女性,50 例(42%)为男性,其中 89 例(75%)为真性视神经 DE(ODE),30 例(25%)为假性视神经 DE(PODE)。非动脉炎性前部缺血性视神经病变(40 例)、颅内压增高(32 例)和前部视神经炎(17 例)被确定为真性 ODE 的病因,而小而拥挤的视盘(12 例)、倾斜的视盘(8 例)、有髓鞘的神经纤维(5 例)和视盘色素(5 例)则是 PODE 的病因。在 ODE 病例中,视神经炎患者最年轻(28.41 岁),而非动脉炎性前部缺血性视神经病变患者最年长(59.98 岁)。非动脉炎性前部缺血性视神经病变患者的首发症状是突然无痛性视力和/或视野丧失,视神经炎患者的疼痛会随着眼球运动而加剧,视力和/或视野丧失,颅内压增高患者会出现头痛和不时视力模糊。弱视导致视力下降的患者占 PODE 病例的 30%,而 70% 的患者是偶然发现的,他们的视力最好。在所有病例中,根据神经眼科检查结果做出初步诊断的准确率为 79%:详细的病史采集和神经眼科检查对于鉴别诊断 ODE 和 PODE 至关重要。

Purpose: This study aimed to identify preoperative factors that predict visual acuity and Kmax 3 years after corneal cross-linking (CXL) in patients with keratoconus (KC), and to develop a prediction model.
Methods: We enrolled 68 patients with KC and followed up on 100 eyes that received CXL for at least 3 years. Preoperative data, including age, UDVA, CDVA, cylinder, SE, and the parameters of tomography including Kmax were collected as predictors. The primary outcomes were changes in CDVA (Delta CDVA) and Kmax (Delta Kmax) postoperatively. Univariate and multivariate linear regression were used to identify the correlation between the primary outcomes and predictors and establish prediction models.
Results: Both CDVA and Kmax remained stable from baseline to 3 years after CXL: from 0.25 ± 0.18 to 0.22 ± 0.20 (P = 0.308) and from 58.70 ± 9.52 D to 57.02 ± 8.83 D (P = 0.187), respectively. Multivariate analysis showed that worse preoperative CDVA (ß coefficient - 0.668, P < 0.001) and lower preoperative Kmean (ß coefficient 0.018,P < 0.001) were associated with greater improvement in CDVA after CXL. A smaller preoperative eccentricity (ß coefficient 8.896, P = 0.01) and a higher preoperative Kmean (ß coefficient - 1.264, P < 0.001) predicted a more flattening of postoperative Kmax. The prediction model for CDVA (R2 = 0.43) and Kmax (R2 = 0.37) could accurately estimate treatment outcomes.
Conclusions: CXL is highly effective in halting or preventing further progression of KC. The preoperative factors CDVA and Kmean were able to predict visual acuity changes 3 years after CXL. And preoperative eccentricity and Kmean could predict Kmax changes 3 years after CXL.

Purpose: To evaluate the correlation between the timing of instilling anesthetic eyedrops prior to intravitreal injection and the patient's perception of pain associated with the injection.
Methods: A prospective observational study which included 192 eyes of 192 patients. Time interval between instillation of Oxybuprocaine-0.4% and Tetracaine-0.5% eyedrops upon checking-in and injection was measured and pain level was evaluated by the 101-point-Numeric Rating Scale.
Results: We found significant correlation between time interval from the first eyedrops to injection and injection related pain. The lowest pain score (11 ± 18) was found in the 11-15 min group, while the highest was found in the 0-6 min (26 ± 25) and in the > 35 min (31 ± 28) groups. The highest percentage of patients without pain was found in the 11-15 min (64%), followed by the 7-10 min (56%) and 16-20 min (47%) groups. 10% or 17% of the 0-6 min or > 35 min. groups, respectively, reported no pain. No patients in 11-15 min group reported severe pain versus 10% in the 0-6 min and 17% in the > 35 min groups. The highest percentage of patients with 'absent-to-mild' pain was in the 11-15 min (89%) and the 7-10 min (87%) compared to all other groups.
Conclusions: Administration of first dose of anesthetic eyedrops within 11-15 min before intravitreal injection yields the lowest levels of injection-related pain, with 7-10 min being second best. Administration of eyedrops outside of this time-window results in higher pain levels avoidable with more attention to the timing issue.

Purpose: Insomnia is a common psychiatric disorder that has oxidative and degenerative effects on the brain. It is thought that the brain's processes affect the retina through their synaptic connections. However, the effects of sleep disorders on the retina and choroid are not fully understood. We aimed to investigate the impact of insomnia on retinal nerve fiber layer (RNFL), central foveal thickness, retinal layers, and choroidal thickness.
Methods: The right eye of 16 healthy controls and 15 patients with insomnia complaints for 3 months, no history of psychiatric drug use, and an Insomnia Severity Index (ISI) score of 15 or higher were included in the study. The retinal layers and RNFL analyses were performed using optical coherence tomography (OCT), and choroidal layers were analyzed using enhanced depth imaging OCT.
Results: Nasal and temporal ganglion cell complex thicknesses were significantly lower in patients with insomnia compared to the controls (97 μm vs. 111 μm P = 0.004; 94 μm vs. 105 μm P = 0.012, respectively). A significant negative correlation was detected between the ISI score and global RNFL thickness (rho, P = 0.03) Additionally, pachychoroid-like vascular structures were observed in choroidal images.
Conclusion: These changes in the retina and the choroid layers due to insomnia may be precursors to retinal degenerative conditions, such as age-related macular degeneration that may occur in the future. Multicenter studies including more patients are needed to demonstrate the importance of quality sleep for eye health.
