RESUMO
PURPOSE: To investigate the inhibitory effect of topically administered azithromycin (AZM), and moxifloxacin (MXF) against tumor necrosis factor-α (TNF-α) production in a rat model of endotoxin-induced uveitis (EIU). METHODS: Thirty-six Wistar albino rats were divided into 6 equal groups. Groups 1, 2 and 3 were determined as sham, control group for topical AZM application and control group for topical MXF application, respectively. Sterile saline, topical AZM 1.5%, and topical MXF 0.5% were instilled 5 times daily for totally 6 days on both eyes of the rats in Group 4, Group 5, and Group 6, before and after inducing EIU by intravitreal injections of lipopolysaccharide, respectively. At 24 h after intravitreal injections, aqueous humor was collected from both eyes of each rat for the assessment of TNF-α concentration. Also, density of nuclear factor kappa B (NF-κB) in ciliary body, and the number of cells infiltrating the posterior segment of EIU rat eyes was assessed in one eye of each rat. RESULTS: There was a significant reduction in mean aqueous humor concentration of TNF-α in EIU rats pretreated with topical AZM in comparison with those pretreated with sterile saline (139 ± 38.6 in Group 4 vs. 72 ± 12.6 in Group 5, p = 0.006). There was also a marked decrease in mean aqueous humor concentration of TNF-α in EIU rats pretreated with topical MXF (139 ± 38.6 in Group 4 vs.86.1 ± 35.5 in Group 6, p = 0.025). Also, evident suppressions were determined in mean density of NF-κB, and in mean number of cells in EIU rats pretreated either with topical AZM, or topical MXF. CONCLUSIONS: Topically applied AZM or MXF may be beneficial in the suppression of TNF-α production in aqueous humor.

BACKGROUND: To determine the repeatability of corneal topography measurements in severe dry eye disease (DED). A comparison of corneal topography parameters between severe DED and healthy subjects was a secondary goal of this study. METHODS: Sixty-nine patients with severe DED and 46 healthy subjects were enrolled in the study. All participants underwent repeated corneal topography measurements with Pentacam (Oculus, Germany) within a half hour time. Both eyes of the participants were used in statistical analysis. A further subcategorization of severe DED patients was performed according to Ocular Surface Disease Index (OSDI) scores: 32-50, 51-70 and 71-100. The repeatability of corneal parameters was assessed with correlation coefficients (CC). RESULTS: The mean age of dry eye patients and healthy subjects were 40.8 ± 13.2 (17-66) and 39.8 ± 8.2 (18-61) years (p:0.604) respectively. No significant differences were found between severe DED and control groups according to analysed corneal parameters in both eyes (p:>0.05). All CCs were greater than 0.9 in severe DED group (p:<0.001). All CCs were also greater than 0.9 in severe DED patients among different OSDI groups (p:<0.001). CONCLUSIONS: Corneal topography measurements are highly repeatable in severe DED with Pentacam. This is the first report about this topic. Nonetheless, further studies are needed with different topography devices for validation.

Objectives: To determine whether treatment time of congenital nasolacrimal duct obstruction (CNLDO) has any effect on refractive amblyopia risk factors (ARFs). Methods: This is a cross-sectional study and it was conducted in the Pediatric Ophthalmology Department at Kayseri City Training and Research Hospital. The ages of 174 patients who underwent probing were obtained from electronic medical charts and used to divide the patients into two groups: an early-probing group (<24 months old) and a late-probing group (≥24 months old). After inclusion criteria were applied, a pediatric ophthalmologist examined 189 eyes of the 174 patients. The groups were evaluated and compared for cycloplegic refractive errors. Results: The median age of patients who underwent probing was 30 months (ranging from 11-44 months). A total of 40 of 189 eyes (21.2%) examined had refractive ARFs, which were significantly more prevalent in the late-probing group (p=0.044). The ARFs associated with astigmatism were greater in the late- versus the early-probing group (p=0.037), whereas no other refractive ARFs or anisometropia differed between the groups (p=0.887 for myopia, p=0.364 for hyperopia, and p=0.672 for anisometropia). Astigmatic ARFs were significantly higher in the late-treatment group. Conclusion: Astigmatic ARFs were significantly higher in the late-treatment group. Therefore, ophthalmologists should regularly monitor the refractive status of children with CNLDO, especially those treated after 24 months old.
RESUMO
PURPOSE: To compare the prevalence, magnitude and type of corneal astigmatism between Turkish individuals and Syrian refugees. MATERIAL AND METHODS: Data of patients scheduled for cataract surgery between January 2019 and 2020 were reviewed. The patients were randomly stratified according to their ethnicity (Turkish individuals or Syrian refugees). Keratometry was performed with the keratometer of IOLMaster 500. Quantitative analysis was performed using the power vector method (J0 and J45). The association between age and astigmatism in the two groups was explored. RESULTS: The study included 4085 eyes of 2049 patients (3962 eyes of Turkish individuals and 123 eyes of Syrian refugees). The mean magnitude of corneal astigmatism, J0, J45 and prevalence of against the rule (ATR) astigmatism and with the rule (WTR) astigmatism were 1.01 D, 0.06, 0.01 D, 37.6% and 43.7% in Turkish individuals and 1.13 D, -0.02, 0.07 D, 46.3% and 37.4% in Syrian refugees, respectively. There were no significant differences according to age, sex, right/left eyes, corneal astigmatism magnitude, keratometric values, J0 and J45 (p > 0.05) between the two groups. Below 40 years of age, the mean corneal astigmatism magnitude in Syrian refugees was significantly higher than that in Turkish individuals (p = 0.037). At all ages, ATR astigmatism prevalence was higher in Syrian refugees than in Turkish individuals. ATR astigmatic shift began at a younger age in Syrian refugees (p = 0.037). Age- and sex-adjusted analysis showed that J0 was significantly lower in Syrian refugees than in Turkish individuals (p = 0.013). CONCLUSION: The prevalence and magnitude of ATR astigmatism were higher and onset earlier in Syrian refugees than in Turkish individuals.

PURPOSE: The primary aim of this study was to assess the practice behaviors of physicians on pediatric vision screening (VS) in primary care settings in Turkey and compare the groups in respect of previous education on VS. METHODS: All physicians working in the primary care settings of Kayseri province of Turkey were directly administered a 24-item questionnaire at planned education seminars. The groups were compared according to a history of VS education (Group 1) and no history of VS education (Group 2). The self-reported questionnaire results were analyzed statistically. RESULTS: A total of 124 of 453 physicians completed the survey with a response rate of 27.3%. VS was reported to be performed as recommended by 70.2% of the participants. The physicians in Group 1 were significantly older (P < 0.05) and more experienced (P < 0.05) than those in Group 2. Group 1 performed the red reflex (RR) test significantly more frequently (P < 0.05) and referred the patients to an ophthalmologist less frequently than Group 2 (P < 0.05). Regression analysis revealed that age (P < 0.05) and previous education (P < 0.05) were the independent factors for visual acuity and RR testing, respectively. Practice-related factors were the most commonly reported barriers to VS in primary care settings. CONCLUSION: Although there is a high rate of reported full adherence to the recommendations for pediatric VS, it seems to be more likely to be performed insufficiently. Practice-related barriers should be handled by publicly available education materials (e.g., YouTube videos). VS education should be added at an earlier stage of medical training programs.

PURPOSE: To evaluate whether the systemic oxidative stress biomarkers increased in patients with vitreomacular traction syndrome (VMT). METHODS: This study compared 25 patients diagnosed with VMT with 20 healthy controls. As a biomarker of systemic oxidative stress, malondialdehyde (MDA) was measured. Total oxidant status (TOS) and total antioxidant status (TAS) were measured to evaluate the systemic oxidant status. RESULTS: Serum MDA values were significantly higher among the patients (p < 0.001). The ideal cut-off value for MDA was determined to be 22.1 µmol/L, with 80% sensitivity and 75% specificity. The between-group differences were not statistically significant for TOS or TAS (p = 0.326 and p = 0.698, respectively). CONCLUSION: Increased MDA levels suggest that systemic oxidative stress may play a role in VMT.

PURPOSE: The aim of this study was to analyze the segmented layers of the macula in patients with obstructive sleep apnea and hypopnea syndrome (OSAS) using spectral domain optical coherence tomography (SD-OCT). MATERIAL AND METHODS: This single-center, cross-sectional study included 31 OSAS patients and 31 age- and gender-matched control subjects. SD-OCT and overnight polysomnography were performed on all participants. The OSAS patients were categorized according to disease severity (mild, moderate, severe). The groups were compared in respect of each segmented macular layer through the use of segmentation software on SD-OCT. Total retinal thickness (RT), peripapillary retina nerve fiber layer (pRNFL) thickness, central corneal thickness (CCT) and intraocular pressure (IOP) values were also compared between the groups. RESULTS: Mean CCT (p:0.015) and nasal pRNFL values (p:0.042) were lower and mean IOP was higher (p:0.018) in OSAS patients than in the control group. The statistical analysis revealed significantly thinner total RT, inner retinal layers (IRL), outer retinal layers (ORL), photoreceptor layers (PRL) and ganglion cell layer (GCL) thicknesses in the OSAS groups compared to healthy subjects. No significant differences were found between the three OSAS subgroups in all segmented macular layers and pRNFL measurements. CONCLUSION: The results of this study showed relatively thinner nasal pRNFL, total RT, IRL, ORL, PRL and GCL layers in OSAS patients compared to healthy subjects. Moreover, this thinning of the segmented layers was unrelated to disease severity.

Purpose: To evaluate the predictive value of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte to high-density lipoprotein (HDL) ratio (MHR) and blood lipid profile in central retinal artery occlusion (CRAO) patients.Methods: We included 37 patients with a diagnosis of CRAO and 36 healthy subjects with similar age-sex in the study. We analyzed the medical records of peripheral blood samples retrospectively. NLR, PLR, MHR were obtained by simple manually calculations.Results: CRAO patients had significantly higher mean NLR in comparison with healthy subjects (p: 0.009). The groups were similar in regard to mean PLR (p: 0.864) and mean MHR (p: 0.581). A cutoff value of >1.62 for NLR was found to be a diagnostic tool in CRAO. The sensitivity and specificity for this cutoff point was 83.8% and 55.6%, respectively.Conclusion: NLR rather than MHR and PLR may be a beneficial marker for the development of CRAO.

PURPOSE: To evaluate the topical glaucoma eye drops adherence prevalence and its association with beliefs and illness perceptions about glaucoma in Turkey. We also aimed to explore the factors linked to patients' total, voluntary, and involuntary non-adherence to medication in different patient attitudes. MATERIAL AND METHODS: A prospective study with cross-sectional design which included a total of 317 glaucoma patients who completed questionnaires. We assessed the adherence to medication, illness perceptions, and the beliefs about the glaucoma treatment by the "Reported Adherence to Medication scale," "the Brief Illness Perception Questionnaire," and "the Beliefs about Medicine-Specific Questionnaire," respectively. According to the RAM scale, voluntary and involuntary non-adherence scores were also distinguished. Different adherence categories in RAM scale were compared with perception and belief measures. Patient attitudes were assessed from the BMQ. We also performed attitudinal type comparisons with different adherence groups. RESULTS: The full adherence prevelance to glaucoma medication was 40%. The proportion of voluntary and involuntary non-adherence was 26% and 57%, respectively. The adherence groups were similar in terms of belief measures but statistically different according to illness perceptions (consequences (p = 0.002), timeline (p = 0.008), personal control (p = 0.001), identity (p = 0.019), concerns (p = 0.003)), and attitude types (ambivalent (p = 0.030) and accepting (p = 0.029)). CONCLUSION: New strategies are required to improve patient adherence to glaucoma medication in Turkey. The beliefs about the glaucoma treatment and illness perceptions are also needed to be enhanced.

INTRODUCTION: The purpose of this study is to evaluate the factors affecting multiple surgeries, worse visual outcome, eye removal (ER) and vitrectomy requirement in terror-related open-globe injuries (OGI) in the Turkish Military. Secondary purpose is to specify surgery and injury characteristics of terror-related OGI. METHODS: A total of 372 eyes of 251 patients with OGI that occurred during terroristic attacks between January 1996 and January 2016 were included in the study. A retrospective investigation of the preoperative variables associated with further surgeries, visual outcome, vitrectomy requirement and evisceration/enucleation was achieved. RESULTS: A total of 1118 separate operative sessions with a median of 2 (1-14) surgeries were performed to 372 eyes. Preoperative factors predicting follow-up surgery included visual acuity (VA) <20/200, lens injury, vitreous haemorrhage (VH), presence of vitreous prolapse. Baseline VA <20/200, initial retinal detachment and ruptured globe injury were the independent factors of worse visual result. Ruptured globe injury (p:0.000) and initial vitreous prolapse (p:0.001) were significantly linked to ER surgery. Patients required vitrectomy significantly tend to have VH (p:0.000) and zone 3 injury (p:0.000) compared with non-vitrectomy group. Single surgery cases tend to have significantly better baseline (p:0.000) and final VA (p:0.007) and shorter follow-up period (p:0.000) compared with multiple surgery group. CONCLUSIONS: Terror-related OGI necessitate remarkable surgical follow-up and multiple surgery sessions with a relatively higher evisceration/enucleation rate than other types of OGI. A comprehensive surgical approach with multiple surgery types is needed to treat terror-related OGI.

PURPOSE: To compare parameters of systemic inflammation and serum lipid levels in patients with pterygium versus healthy individuals. METHODS: Thirty-five patients with pterygium and 30 healthy individuals were enrolled as two respective groups in a retrospective study. The participants' complete blood count (CBC) parameters and levels of serum total cholesterol, low-density lipoprotein, high-density lipoprotein (HDL), and triglycerides (TG) were obtained from digital records and compared. Their neutrophil/lymphocyte, platelet/lymphocyte, and monocyte/HDL ratios were calculated and compared as well. As secondary outcomes, longitudinal length (LL), basal length (BL), and total area (TA) of pterygium among the patients were quantitatively measured by using ImageJ software. Correlations between serum parameters and pterygium measurements were analyzed. RESULTS: Although between-group differences in CBC parameters and the ratios were not statistically significant, HDL levels were significantly lower (p = 0.014) and TG levels significantly higher (p = 0.031) among patients with pterygium than among the controls. A positive correlation was detected between the patient's age and the pterygium's BL (p = 0.002, r = 0.516), LL (p = 0.00, r = 0.547), and TA (p = 0.00, r = 0.515). Neutrophil levels negatively correlated with LL (p = 0.025, ß = - 0.308) and TA (p = 0.002, ß = - 0.420). CONCLUSION: Local instead of systemic inflammation should be considered in the management of pterygium. Besides, decreased HDL levels may indicate systemic oxidative stress in patients with the condition.

INTRODUCTION: The ocular trauma score (OTS) is a widely used predictive tool in determining the visual prognosis of ocular injuries. Intraocular-foreign-body (IOFB)-type injuries comprise the leading type of open-globe injuries (OGI) in ocular combat injuries. However, there are scarce reports evaluating the efficacy of OTS in IOFB-type injuries. Only one study is available that explored the validity of OTS in combat-related IOFB injuries with a limited number of eyes. The aim of this study is to confirm the predictive value of OTS in lethal-weapon (LW)-related OGI with IOFB. MATERIAL AND METHODS: The charts of 488 patients with IOFB-type-eye injuries between January 1998 and January 2018 were analyzed. Only the LW-related ocular injuries were included. Baseline details (patient demographics, surgeries, OTS categories, and visual acuity [VA]) were recorded. To test the validity of OTS, Fischer exact test was used to compare the likelihood of the final VAs for every OTS subgroups between OTS study group and this study. RESULTS: The complete data of 206 eyes of 142 patients including two civilians were analyzed in the study. No subjects had ocular protection at the time of the injury. OTS study and this current study did not show an exact validation in first three OTS categories in various final VA subgroups (no light perception (NLP) subgroup (P: 0.001), light perception/hand movements subgroup (P: 0.033), 20/200 to 20/50 subgroup (P: 0.047) in OTS category 1; NLP subgroup (P: 0.000), 20/200 to 20/50 subgroup (P: 0.036), 20/40 subgroup (P: 0.018) in OTS 2; and 20/200 to 20/50 subgroup (P: 0.01), 20/40 subgroup (P: 0.003) in OTS 3, respectively). The above results indicate that in first three OTS categories, OTS study was not useful in visual prognosis prediction in the mentioned VA subgroups. The results predicted the final VA only in OTS categories 4 and 5 in which all P values were greater than 0.05. CONCLUSIONS: Visual outcome of this type of ocular injury may be unpredictable due to more frequent discouraging results. OTS failed to predict visual outcome in first three OTS categories in this study. Therefore, OTS appears to be verified only in better (OTS categories 4 and 5) categories.

INTRODUCTION: Empty bullet-related ocular injuries (EBOI) are rare and may result in unfavorable visual outcomes due to both open globe and closed globe injuries. To our knowledge, no reports of such injuries in terms of outcomes have been previously described in the literature. The aim of this study was to describe the treatment performed and ocular outcomes of such injuries. MATERIALS AND METHODS: EBOI of 23 cases were reviewed who were referred to Gulhane School of Medicine Department of Ophthalmology between January 1998 and January 2018. Patient demographics, ocular signs (initial and final), injury types, type and number of interventions, and ocular trauma scores were recorded. RESULTS: In total, 23 eyes of the 23 patients with an average age of 22.3 ± 4.54 years (range, 20-41 years) were included in the study. All of the patients were male, and all injuries were due to empty bullets during shooting training. None had ocular protection at the time of ocular injury. Fourteen patients (60.9%) were open globe injuries, whereas nine (39.1%) of them were closed globe injuries. Mean ocular trauma scores category of the cases was 2.52 ± 1.03. The baseline and final visual acuity was 20/200 or better in 21.7% and 69.5% of eyes, respectively. Nineteen eyes (82.7%) had undergone a total of 31 surgeries with a 1.34 ± 0.88 surgery average. CONCLUSIONS: The prognosis of EBOI is unpredictable and is dependent on the severity of ocular damage. The best treatment option is prevention of EBOI with protective eyewear.

PURPOSE: To determine prognostic factors for open-globe Injuries (OGI). METHODS: Open-globe injuries referred to a tertiary referral clinic in Turkey between January 1998 and January 2016 were retrospectively analyzed. Univariate and multivariate logistic regression analyses were conducted to find out the most important variables for poor visual outcome. RESULTS: Six hundred and thirty-three patients were studied with an average age of 24.37 ± 11.1 years (range 1-80).The male/female ratio was 18.6/1. Most of the cases (48.2%) were conflict related, whereas the rate of work, accidental, and sports related cases were (33.1%), (17.9%) and (0.01%), respectively. Final visual acuity (VA) ranged from no perception of light (23%) to 200/200 (17.1%). The number of cases with a final VA > 20/200 were 388 (49.3%). Initial visual acuity < 20/200, ocular trauma score category 1, zone 3 injury, additional vitrectomy surgery, and lens damage were found to be the main variables related with poor visual outcome in multivariate logistic regression analysis. CONCLUSION: Besides ocular trauma score category and initial VA; zone of injury, additional surgeries, and initial lens damage had negative effects on visual outcome in OGI.

INTRODUCTION: Sniper shot ocular injuries (SSOI) are rare and result in poor ocular outcomes due to high energy transfer both to the eye and the adjacent brain. To our knowledge, no reports of such injuries in terms of outcomes have been previously described in the literature. The aim of this case series was to describe the treatment performed and ocular outcomes of such injuries. METHODS: Five cases of terroristic SSOIs referred to Gulhane Military Medical Academy Department of Ophthalmology between 22 July 2015 and 30 January 2017 were reviewed. Comparisons were made between the location and mechanism of injury, initial and final ocular signs, interventions and additional extraocular injuries. RESULTS: Two cases were of police officers and the remaining were Turkish military soldiers. All of our cases were injured in urban district by terrorist snipers hidden in apartments. Four individuals were injured in the right eye and the other was injured bilaterally. Initial visual acuities (VA) ranged from no light perception (NLP) to 0.0 with logMAR. Final VA raised to 0.0 in three patients whereas in two of NLP patients it remained the same. Mean Ocular Trauma Score was 2.2. Two eyes necessitated evisceration and the others underwent vitrectomy surgery. CONCLUSIONS: The prognosis of SSOI is unpredictable and is highly dependent on the trajectory and energy deposition. Primary evisceration or enucleation should be reserved to severely ruptured globe cases with no chance of globe-saving procedures. If the globe remains intact, retinal and vitreal damage should be repaired. Due to risk of associated intracranial injury, all patients should be referred for neurosurgical opinion.

Bilateral simultaneous nonarteritic anterior ischaemic optic neuropathy (NAION) is extremely rare. A 57-year-old woman presented with bilateral optic disc oedema and peripapillary splinter haemorrhages. Initial visual acuities were hand movements in the right eye and light perception in the left eye. The patient had a mildly elevated diastolic blood pressure and glucose intolerance. Erythrocyte sedimentation rate and C-reactive protein levels were within normal limits. Temporal artery biopsy was negative for temporal arteritis. Marked visual improvement occurred in both eyes (0.8 in the right eye, 0.6 in the left eye) after systemic steroid therapy in the 16th month of follow-up.
