Objectives: To review the current literature related to the correlation between translaminar pressure difference (TLPD) and glaucoma. Materials and Methods: In this article, we conducted a literature review using MEDLINE via PubMed, Cochrane Eyes and Vision, and Google Scholar from 01/01/2010 to 31/12/2022. Search terms included “glaucoma”, “intraocular pressure”, “translaminar cribrosa pressure gradient/difference”, “intracranial pressure”, and “cerebrospinal fluid pressure”. Of 471 results, 8 articles were selected for the meta-analysis. Results: Our meta-analysis demonstrated significantly higher intraocular pressure, lower cerebrospinal fluid pressure (CSFp), and greater TLPD in high-tension and normal-tension glaucoma groups compared to healthy groups. Conclusion: The differences in CSFp and TLPD between glaucoma and healthy people detected in current studies suggests a potential relationship between TLPD and glaucoma.

Objectives:To investigate the effects of phacoemulsification with intraocular lens implantation (phaco+IOL) surgery on intraocular pressure (IOP) and anterior segment parameters in patients with cataract and primary angle-closure glaucoma (PACG).Materials and Methods:Fifty-five patients with PACG undergoing phaco+IOL surgery were evaluated in terms of best corrected visual acuity (BCVA), IOP, anterior chamber depth (ACD), aqueous depth (AD), and lens thickness (LT) measured by optical biometry preoperatively and at the 6-month postoperative visit. They were compared with 34 healthy age-and gender-matched cataract patients who underwent phaco+IOL surgery.Results:Preoperative evaluation revealed higher IOP, shorter axial length, shallower ACD and AD, and greater LT in the PACG group (p

Objective: We aimed to compare the intraocular pressure (IOP), keratometry values (K), and anterior segment parameters of patients with clinically unilateral pseudoexfoliation syndrome (PEX) with the other eyes without PEX and the control group. Material and Method: Fifty four patients with unilateral PEX findings and 40 participants without PEX findings in both eyes were included in the study as a control group. IOP was measured by Goldmann applanation tonometry. K values and anterior segment parameters [central corneal thickness (CCT), anterior chamber depth (ACD), iridocorneal angle (ICA), and anterior chamber volume (ACV)] were measured using Scheimpflug imaging technique. Results: The mean age of PEX patients was 67.9±9.2 years, while the mean age of the control group was 58.9±5.7 years. The IOP values of the eyes with PEX were significantly higher than the other eyes (p=0.02), and there was no significant difference between them and the control group (p=0.59). In terms of K values and anterior segment parameters, the measurements of eyes with PEX and the other eyes, and eyes with PEX and control group were similar (p gt;0.05). Conclusion: In our study, eyes with PEX had higher IOP values than the fellow eyes and control group. In addition, thinner CCT, narrower ACD, and ICA values were found in eyes with PEX than in the other eyes. However, these values were not statistically significant.

Objective: Evaluation of whether the Neodymium: Yttrium Aluminium Garnet (Nd: YAG) laser produces quantitative changes in macular and peripapillary microvascular structures, and choriocapillaries during Nd: YAG laser capsulotomy for posterior capsular opacification (PCO). Material and Method: A total of 186 patients who underwent capsulotomy for PCO with Nd: YAG laser with a total energy of less than 50 mJ and without damaging the anterior vitreous were studied. Inflammation and intraocular pressure (IOP) increase that may develop after laser were controlled with medication. Optical coherence tomography (OCT) and OCT-angiography measurements were made in 59 eyes of 59 patients who met the study criteria, within ½ hour post-laser and on the 30th day. Since the fellow eyes of 28 patients had an intraocular lens and didn’t have PCO, measurements were also made in fellow eyes. The measurements of the fellow eyes were compared with those of the laser-treated eyes. Results: There was no difference between macular microvascular vessel densities (VDs), radial peripapillary capillary VDs, choriocapillaris flow areas, retina nerve fiber layer thicknesses, macular thicknesses, subfoveal choroidal thicknesses measured within half an hour after laser, and measured on the 30th day. There was no difference between the measurements in fellow eyes and those in laser-treated eyes. Conclusion: In capsulotomy for PCO, it was observed that the Nd: YAG laser, which was applied with a low total energy and without disturbing the anterior vitreous, by keeping the inflammation and IOP increase under control, didn’t cause quantitative changes in the choriocapillaries, macular and peripapillary microvascularity, and it was safe as a result.

INTRODUCTION: Specific Learning Disorder; is a neurodevelopmental disorder that arises due to genetic, epigenetic and various environmental factors. The aim of this study is to compare children and adolescents diagnosed with specific learning disorder with healthy controls in terms of intraocular pressure, retinal nerve fiber layer, central macular thickness and choroidal thickness. METHODS: This prospective case-control study included 63 children and adolescents, including 30 with specific learning disabilities and 33 controls. The case and control groups were assessed using ‘Schedule for Affective Disorders and Schizophrenia School-Age Children-Present and Lifetime Version Form-DSM-5 Turkish Version for diagnostic interview. Case and control groups were compared in terms of retinal findings by performing intraocular pressure and optic coherence tomography. In the study, various retinal nerve fiber layer quadrants were compared separately for the right and left eyes. RESULTS: In the case group, only the right eye superior nasal retinal nerve fiber layer quadrant thickness was found to be lower than the control group. There was no difference between the groups in terms of other parameters. DISCUSSION AND CONCLUSION: Our study indicates a lower right eye superior nasal retinal nerve fiber layer quadrant thickness in children and adolescents with specific learning disorder as compared to controls. However, there was no difference between the groups in terms of intraocular pressure and other retinal findings. Longitudinal studies with larger samples are needed in order to generalize retinal findings in specific learning disorder to the population.

Objectives:To investigate the intraocular pressure (IOP)-lowering efficacy, safety, and treatment tolerability of brinzolamide/ brimonidine fixed combination (BBFC) in maximum medical therapy.Materials and Methods:The medical records of 92 patients with glaucoma or ocular hypertension who had previously been treated with a different antiglaucomatous regimen and were switched to a treatment regimen that included BBFC were retrospectively analyzed. Patients were divided into 4 groups including 22, 20, 27, and 23 patients based on previous glaucoma treatment. All patients received maximum medical treatment regimen by adding a combination of beta blocker-prostaglandin analogue therapy along with BBFC. IOP values at baseline and month 1, month 3 and month 6 after starting BBFC and ocular adverse effects at follow-up visits were evaluated.Results:The mean age of all patients was 62.7±16.6 years (range: 18-90). Fifty-two patients (56.5%) were women and 40 (43.5%) were men. Forty-eight (52.2%) patients had primary open-angle glaucoma, 35 (38.0%) had pseudoexfoliation glaucoma, and 9 (9.8%) had ocular hypertension. The IOP of the all eyes was 21.1±4.8 mmHg (range: 17-25) before and 17.6±3.7 mmHg, 17.3±3.4, and 17.0±3.5 mmHg at month 1, 3, and 6 after the introduction of BBFC, respectively (p

Objective: To compare the short-term effects of preservative-free and preserved 0.15% brimonidine tartrate on intraocular pressure (IOP) and ocular surface in glaucoma patients. Material and Method: Forty eyes of 20 patients who were diagnosed with primary open-angle glaucoma in our clinic, had no previous treatment and had no ocular surface disease were included in the study. The first group were started on 0.15% brimonidine tartrate without preservatives, and the second group were started on 0.15% brimonidine tartrate with preservatives. IOP, corneal and ocular surface staining score (Oxford Scale), tear breakup time (BUT), ocular surface disease index (OSDI), and tear meniscus height were evaluated at the first admission of the patients and at the 6thmonth follow-up after the initiation of drug therapy. Results: The mean age of the patients was 57.21±9.29 years. The mean IOP before and after treatment were measured as 21.30±1.72, 20.70±1.69 and 16.35±0.88 mmHg, 15.75±1.65 mmHg, OSDI scores 16.39±8.17, 16.41±8.12 and 28.93±8.97, 35.05±16.05, respectively. Average BUT 18.60±3.69, 18.65±3.64 and 13.25±2.38, 11.45±4.08 sec, average ocular surface staining was 0.20±0.25, 0.18±0.15 and 0.20±0.41, 0.60±0.68. Mean meniscus height was 320.23±73.94, 315.72±85.92 and 295.24±125.12, 285.75±138.45 micrometers. When the first and sixth month results of both groups were compared, there was a statistically significant difference in IOP and ocular surface findings (p <0.05). When the two groups were compared at the sixth-month, there was only a statistically significant difference on the Oxford scale (p <0.05). Conclusion: Preservative-free anti-glaucomatous therapy may be preferred in glaucoma patients to reduce symptoms related to ocular surface problems, increase effective IOP control and drug compliance.

Intra ocular pressure was 12 mm Hg in her right eye,8 mm Hg in her lef eye. Facoemulsification was performed. Visual acuity was found 0.8 after one week postoperatively. [ABSTRACT FROM AUTHOR]

Objective: The effects of laryngoscopy on hemodynamic response and intraocular pressure (IOP) are well known. The use of Supraglottic Airway Devices (SGAD) provides more stable hemodynamic parameters. Aim of this study is to compare the effects of laryngoscopic intubation on hemodynamic responses and IOP with intubation using Cobra Perilaryngeal Airway (Cobra-PLA) and Intubating Laryngeal Mask Airway (ILMA), without laryngoscopy. Methods: Sixty ASA I-II patients, without history of difficult intubation or ophtalmic pathology were randomly allocated into Cobra-PLA (G-PLA), ILMA (G-ILMA), and laryngoscopic intubation (G-L) groups. Induction was achieved with intravenous lidocaine 0.5 mg kg-1, propofol 1.5-2.5 mg kg-1 and rocuronium 0.6 mg kg-1. Propofol infusion of 2-4 mg kg-1 h-1 was continued until the 10th minute following intubation. Intubation was achieved by placing endotracheal tubes through the SGAD into the trachea in G-PLA and G-ILMA, and with a laryngoscope in G-L. Hemodynamic parameters and IOP were recorded before and after induction, the placement of SGAD, before and after intubation, extubation. Results: Demographic characteristics, mouth opening, thyromental distance, and Mallampati score of the groups were similar. Heart rate was significantly higher in G-L than the other groups after intubation (p<0.05). Mean arterial pressure increased with intubation and extubation in all groups, these changes were similar among groups. In comparison between groups, Mean IOP was found to be higher in G-L at the 1st, 2nd and 10th minutes after intubation compared to G-PLA and G-ILMA (p<0.05). Conclusion: It has been found that intubation without laryngoscopy with Cobra-PLA and ILMA cause similar hemodynamic response, especially intubation with Cobra-PLA leads to less IOP rise compared to laryngoscopic intubation.

ÖZET Amaç: Histeroskopi öncesinde, esnasında ve sonrasında göz içi basıncı (GİB) değişimlerini değerlendirmek ve iki farklı histeroskopi metodunda ölçümleri karşılaştırmak Gereç ve Yöntem: Bu retrospektif çalışmaya, Ekim 2017-Şubat 2020 tarihleri arasında bir üçüncü basamak üniversite hastanesinin Kadın Hastalıkları ve Doğum kliniğine başvuran ve histeroskopi işlemi uygulanan 52 kadın hasta dahil edildi. Katılımcılar yaş, vücut kitle indeksi ve cerrahi öncesi GİB değerlerine göre eşleştirildi ve histeroskopi yöntemine iki eşit gruba ayrıldı; monopolar prob-glisin 1.5% solüsyon (MG) ve bipolar prob- izotonik solüsyon (BI). Cerrahi öncesi, esnasında ve 12 saat sonrasında GİB ölçümleri taşınabilir tonometri cihazı kullanılarak yapıldı. Bulgular: Katılımcıların ortalama yaşı MG grubunda 50.69±7.56 yıl, BI grubunda ise 52.69±6.66 yıldı. Cerrahi öncesinde, esnasında ve sonrasında ortalama GİB ölçümleri MG grubunda sırasıyla 13.69 ± 2.22, 26.62 ± 3.08, 14.69 ± 2.57 mm-Hg ve BI grubunda sırasıyla 13.38 ± 1.81, 20.31 ± 2.05, 13.69 ± 1.59 mm-Hg idi. Her iki grupta da cerrahi esnasında ortalama GİB ölçümleri cerrahi öncesi ve sonrasına kıyasla anlamlı olarak yüksekti. Ancak, cerrahi öncesi ve sonrası değerler arasında her iki grupta da anlamlı fark yoktu. Sonuç: Her iki yöntemde de histeroskopi esnasında GİB pikleri meydana geldi ve monopolar prob ve glisin 1.5% solüsyonu kullanımı belirgin olarak daha yüksek dalgalanmalara neden oldu. Bu nedenle, cerrahi esnasında GİB’nın yakın izlemi ciddi oküler komplikasyonların gelişimini önleyebilir. Anahtar Kelimeler: Glisin; histeroskopi; göz içi basıncı; tonometri

Objectives:To evaluate the effect of body position on intraocular pressure (IOP) measurement in the pediatric age group.Materials and Methods:Children whose general condition was healthy and ophthalmic examination was within normal limits were included. Forty-nine eyes of 49 pediatric patients were included in the study. IOP was measured with an ICARE rebound tonometer (ICARE PRO; ICARE, Helsinki, Finland) while patients were in standing, sitting, and supine positions. Differences between the consecutive measurements were compared statistically.Results:Twenty-two of the 49 patients were female, 27 were male. The mean age was 9.61±2.66 (5-15) years. Mean IOP values in the standing, sitting, and supine positions were 18.81±2.97 (11.6-26.2) mmHg, 18.88±3.44, (12-28.2) mmHg, and 19.01±2.8 (13.5-25.9) mmHg, respectively. There were no statistically significant differences in pairwise comparisons of the measurements taken in the different positions (p=0.846, p=0.751, p=0.606). There was a statistically significant correlation between corneal thickness and intraocular pressure values in all measurements (p=0.001, r=0.516).Conclusion:IOP values measured with the ICARE rebound tonometer in healthy children are not affected by body position.

Objectives:To evaluate the early effects of femtosecond laser-assisted in situ keratomileusis (LASIK) surgery on retinal ganglion cell thickness (GCT), peripapillary retinal nerve fiber thickness (NFT), and central macular thickness (CMT) obtained by spectral domain optical coherence tomography (SD-OCT) in a healthy population.Materials and Methods:This case-control study included data from the right eye of 40 subjects without any disease other than refractive error and who had undergone femtosecond LASIK surgery. The preoperative, postoperative 1-hour, and postoperative 3-week GCT, NFT, and CMT values obtained by SD-OCT were compared.Results:The mean age was 27.54±5.99 years (18-45 years). GCT, NFT, and CMT were 18.43±6.03 μm, 107.90±9.01, and 234.3±21.2 μm preoperatively; 18.05±5.93 μm, 108.08±8.92 μm, and 230.1±22.6 μm at postoperative 1 hour; and 17.86±5.27 μm, 107.98±10.13, and 236.3±25.1 μm at postoperative 3 weeks (p=0.159, 0.85, and 0.254, respectively).Conclusion:There were no changes in GCT, NFT, and CMT values evaluated with SD-OCT in the early period after femtosecond LASIK surgery.

Amaç: Katarakt cerrahisi sonrası göz içi basıncı (GİB) ve merkezi kornea kalınlığı (MKK) değişimlerini incelemek. Gereç ve Yöntem: Çalışmaya senil kataraktı bulunan 62 hastanın 62 gözü dahil edildi. Tüm hastalar komplike olmamış fakoemülsifikasyon ve göz içi lensi (GİL) implantasyonu içeren katarakt cerrahisi geçirdiler. GİB, nonkontakt tonometre ile katarakt ameliyatından önce ve sonrasında 3. saatte, 1. günde, 1. haftada, 2. haftada ve 1. ayda ölçüldü. GİB ve MKK ölçümleri tekrarlanan ölçümler için varyans analizleri (ANOVA) ile test edildi. Bulgular: Çalışmaya ortalama yaşları 66±12.38 (40-84) olan 62 hasta dahil edildi. Hastaların 35'i kadın (% 56.5), 27'si (% 43.5) erkekti. Preoperatif ortalama MKK 535,69 µ idi. Preoperatif ortalama GİB 14.63 (10-21) mmHg idi. GİB, 3. saatte 19,95 (9-58), 1. günde 14.50 (8-29), 1. haftada 12.83 (8-19), 2. haftada 12.91 (7-18), 1. ayda 12.72 (8-18) idi. Preoperatif GİB 14.63 mmHg iken 3. saatte istatiksel anlamlı olarak 19,95 mmHg'ya (%26) yükseldi (p lt;0.001). 1. günde ise istatiksel olarak anlamlı şekilde 14.5 mmHg'ye düştü (p lt;0.05). Preoperatif ve postoperatif 1. gün arasında istatiksel olarak anlamlı fark yoktu (p gt;0.05). 1. gün ve 1. hafta arasında 1.67 mmHg düşüş görüldü. Bu fark istatiksel olarak anlamlı idi (p lt;0.05). Gözlerin 7'sinde ciddi derecede GİB yüksekliği mevcuttu ( gt;30 mmHg). Bu gözlerde herhangi bir tedaviye gerek duyulmadan GİB normale döndü. Sonuç: Katarakt cerrahisi sonrası ilk saatlerde anlamlı şekilde GİB yükselmekte. 1. günde ise normale dönmektedir. GİB'teki yükselmeler sağlıklı gözlerde muhtemelen zararsızdır, fakat riskli optik diskli hastalarda geçici yükselmeler dahi zararlı olabilir. Risk altındaki hastalarda GİB yükselmesi için gerekli önlemler alınmalıdır.

Objectives:To compare intraocular pressure (IOP) measurements obtained with the Icare Pro tonometer used in clinical practice, and the Icare One self-tonometer.Materials and Methods:Fifty-two eyes of 52 healthy, right-handed individuals with no prior intraocular surgery or ocular trauma, structural ocular pathology, or systemic disease were evaluated. IOP was first measured using the Icare Pro tonometer. The participants were then told how to use the Icare One tonometer and asked to measure their own IOP. The results were analyzed statistically using SPSS v.24.Results:Of the 52 healthy participants, 16 (30.7%) were male and 36 (69.3%) were female. Their mean age was 31.6±6.3 (23-47) years. Mean IOP measured with the Icare Pro was 17.10±6.2 (11.5-25.2) mmHg, and the mean self-measured IOP with Icare One was 14.01±3.4 (7-24) mmHg. When the two methods were compared using Levene’s t test, there was a significant mean difference of -3.08±0.6 (95% confidence interval: -4.39 -1.78; p

Objectives:It is important to determine variables that influence intraocular pressure (IOP) measurement. This study aimed to evaluate the effect of body position on IOP.Materials and Methods:The study included 52 right eyes of 52 patients who presented to the ophthalmology department of our hospital and had no ocular disease except refractive errors. IOP was measured with an Icare PRO tonometer while patients were in sitting, standing, and supine positions, with intervals of 10 minutes between the positions. Correlations between the results were evaluated using Spearman’s correlation analysis and Wilcoxon tests.Results:Thirty-six of the 52 patients were female, 16 were male. Mean age was 31.65±6.30 (23-47) years. Mean IOP values in the sitting, standing, and lying positions were 17.76±3.41 (12.70-25.60) mmHg, 17.10±3.27 (11.50-25.20) mmHg, and 18.46±4.67 (10.50-29.40) mmHg, respectively. There were no statistically significant differences between measurements taken in the different positions (p=0.112, p=0.472, p=0.071). We observed that there was no relationship between age and body position (p>0.45, p>0.79, p>0.77) or between gender and position (p>0.59, p>0.69, p>0.54).Conclusion:Gender and age had no effect on IOP measured in different body positions. There were also no significant differences between IOP values measured in the different positions. Therefore, we believe the portable Icare PRO tonometer can be used for patients who are confined to bed and will provide IOP measurements that are concordant with values obtained while sitting.

Purpose: To evaluate the complications encountered in the postoperative period as well as anatomic results following the removal of silicone oil tamponade in patients undergoing 23 gauge pars plana vitrectomy (PPV) and silicone oil endotamponade for diabetic tractional retinal detachment. Materials and methods: Fifty-nine eyes of 54 patients who underwent surgery for diabetic tractional RD between January 2015 and April 2016 in our clinic were included in the study. The files of the cases were examined retrospectively. Age, gender, duration of silicone oil endotamponade, best corrected visual acuity (BCVA), intraocular pressure (IOP), redetachment rate and other postoperative complications were evaluated. Results: 35 of the patients were female (64.8%) and 19 were male (35.2%). The mean age was 59.1 ± 10.2 (29-80) years. The preoperative mean BCVA was 0.06 ± 6.6 (0.03-0.4), while the postoperative mean BCVA was 0.10 ± 13.3 (0.03-0.7). The preoperative and postoperative mean IOP were 16.3 ± 6.04 and 14.3 ± 4.1 mmHg, respectively. The mean duration of silicone oil endotamponade was 6.8 ± 4.01 (2-24) months. Cataract surgery was performed in 31 (52.5%) patients as removing silicone oil endotamponade. Postoperative complications were transient severe hypotony in one eye (1.7%), transient hypertony in three eyes (5.08%), vitreous hemorrhage requiring surgery, hyphema and hypopyon in one eye (1.7%) and redetachment in four eyes (6.8%). Conclusion: In patients who underwent pars plana vitrectomy and silicone oil endotamponade due to diabetic tractional retinal detachment, ocular hypotonia or hypertonia and vitreous hemorrhage may rarely develop, besides retinal redetachment, following removal of silicone oil endotamponade.

Purpose: To evaluate the factors affecting visual prognosis in bilateral pediatric cataracts and the complications of surgery. Materials and method: The records of 40 patients operated for bilateral congenital cataract at GÜTF Eye Clinic between 2010-2018 were retrospectively analyzed. Peroperatively capsulotomy, lens aspiration, posterior capsulotomy and anterior vitrectomy were performed. Primary iol implantation was performed in cases over one year of age. Secondary IOL implantation was performed at 2 years of age unless contraindicated. Visual acuity, intraocular pressure, presence of strabismus, amblyopia, nystagmus and surgical complications were evaluated. Results: The mean follow-up period was 4 years (1 month-8 years). 22 of the cases were male (55%) and 18 were female (45%). Seventeen patients (42.5%) underwent surgery before 3 months of age, and 23 patients (57.5%) underwent surgery after 3 months of age. 8 out of 30 patients who left aphakic went for secondary IOL implantation at the mean age of 5 years. The mean postoperative BCVA was 0.4 logMAR±0.4 (P +/ - 0 logMAR). The BCVA of the group undergoing IOL implantation was statistically higher (p = 0.007). Nystagmus was present in 6 out of 22 patients who left aphakic where postoperative nystagmus was recorded 3 out of 18 patients with IOL implanted. Two cases showed posterior capsule opasification, where, 1 retinal detachment, 1 glaucoma and 1 IOL subluxation cases were recorded as complications. Conclusion: IOL implantation was associated with good visual prognosis and the presence of nystagmus was associated with poor visual prognosis in bilateral childhood cataracts.

Purpose: Evaluation of macular retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), and ganglion cell complex (GCC) in pseudoexfoliation syndrome (PES) by spectral domain-optical coherence tomography (SD-OCT). Material and methods: One eye of 30 patients with PES and one eye of 30 healthy subjects were included in the study. The participants' macular screening was performed in 9 quadrants by SD-OCT according to the early treatment diabetic retinopathy study (ETDRS). Retinal layers were automatically divided into segments using SD-OCT's own software and analyzed separately. Results: Statistically thinning was observed in the perifoveal nasal quadrant in RNFL (p = 0.035); in the perifoveal nasal (P = 0.041) and inferior quadrants (p = 0.034) in GCL and in the perifoveal nasal quadrant (p = 0.035) in GCC of the PES group when compared to the control group. There was no significant difference between the two groups in the inner plexiform layer (p<0.05). Conclusion: Although intraocular pressure is normal in patients with PES, retinal ganglion cell damage may develop. The evaluation of RNFL, GCL, and GCC with SD-OCT in patients with PES may help in the early diagnosis of preperimetric glaucomatous damage. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to evaluate intraocular pressure (IOP) and retinal nerve fiber layer (RNFL) changes in patients with carotid artery stenosis (CAS) after carotid artery stenting. Materials and Methods: This study was conducted as a cross-sectional, non-randomised clinical case series. Fifteen male patients (mean age: 63.6±9.1) with CAS and more than 70% carotid artery narrowing were included. All of the patients were followed in the department of neurology and were operated in the interventional radiology division. Eighteen healthy male subjects (mean age: 63.7±5.3) were included in the control group. All of the healthy subjects had a detailed ophthalmological examination and subjects with any chronic eye disease were excluded from the study. All of the participants had a detailed ophthalmological examination including tonometry using Goldmann applanation tonometry and RNFL analysis using optical coherence tomography (RTVue-100 5.1). Results: There were no ocular ischemic symptoms in any of the participants. The mean IOP value was 15.1±2.1 mmHg in the control group and 16.6±2.4 mmHg before stent implantation, 16.4±2.2 mmHg at 1 week after implantation, 16.6±2.5 mmHg at 1 month after implantation, and 16.7±2.9 mmHg at 3 months after implantation in the CAS group. Mean RNFL thickness was 105±6 µm in the control group; in the CAS group, mean RNFL thickness values were 98±27 µm before stent implantation and 103±11 µm, 101±10 µm, and 101±11 µm at 1 week, 1 month, and 3 months after stenting. There were no significant differences between the CAS group and control group regarding IOP and RNFL thickness values (p>0.05). IOP and RNFL thickness also did not show any statistically significant changes from preoperative measurements in 3 months postoperative follow-up in the CAS group (p>0.05). Conclusion: IOP and RNFL thickness remained unchanged after carotid stent implantation in carotid artery stenosis patients with no signs of ocular ischemic syndrome.

Trauma is one of the leading causes of death worldwide. Stress response secondary to injury occurs at these patients. Because of pain respiratory rate can increase at them. In this regards airway management and hemodynamic stability are important parameters in trauma patients. Ketamine has noncompetitive antagonistic properties on the receptor of N-methyl-D aspartate (NMDA) and it can stimulate brainstem by noradrenalin reuptake inhibition. For that it can be used on monitorization of hemodynamic unstable trauma patients which monitorization is not suitable. We aimed to investigate the frequency of ketamine use in clinical practice in trauma patients and whether it is the preferred agent in traumatic brain injuries and injuries with increased intraocular pressure (IOB) by reviewing the literature.

Purpose: To evaluate ganglion cell complex (GCC) thickness in patients with neovascular age-related macular degeneration (AMD) who underwent aflibercept injection by using optical coherence tomography (OCT). Methods:The study included 28 eyes of 28 patients with neovascular AMD who had at least 6 months of follow-up following 3-dose anti-VEGF injection. Central macular thickness (CMT) and GCC thickness were evaluated with SD-OCT. Visual acuity, intraocular pressure, CMT, GCC thickness were recorded at the first month, 3 months and 6 months after the injection. Results:The mean age of the patients was 71.9 ± 7.2 (55-82) years. Best corrected visual acuity (logMAR) before injection was 0.90±0.24, at third month it was 0.32±0.22 idi (p=0.005). Before injection the mean CMT was 383.75 ± 28.6 µm, it was 267 ± 67 µm in the 6th month (p = 0.001). Mean GCC thickness was 93.20 µm before injection and 92.56 µm at 6 months. (P = 0.250) Conclusion: It was found that intravitreal Aflibercept injection did not have a significant effect on GCC thickness after 6 months of follow-up. Aflibercept is an effective, reliable treatment option in the treatment of neovascular AMD. [ABSTRACT FROM AUTHOR]

Purpose: Evaluation of the outcome and prognosis of trabeculectomy and Ahmed Glaucoma Valv (AGV) implantation in patients with neovascular glaucoma (NVG). Materials and Methods: The fi les of patients with NVG who underwent trabeculectomy with mitomycin C and AGV implantation between April 2012 - May 2017 were retrospectively analyzed. Detailed ophthalmologic examination was performed at the time of admission and at the controls. Age, sex, follow-up period, best corrected visual acuity (BCVA), intraocular pressure (IOP), complications were recorded. IOP between 5 and 21 mmHg was accepted as surgical success. Paired-t test was used for statistical analysis, p<0.05 was considered significant. Results: Twenty of 40 patients with NVG underwent trabeculectomy and 20 of them had AGV implantation. In the trabeculectomy group, 12 (60%) were male and 8 (40%) were female, age 54.3 ± 15.56; In the AGV group, 11 (55%) were male and 9 (45%) were female and their age was 53.1 ± 18.59. The follow-up period was 14.3 months in the trabeculectomy group and 15.1 months in the AGV group. There wasn't statistically significant difference in visual acuity between groups at the time of admission and at the 12th month (p=0.41). IOP was 42.35±8.66 mmHg in the trabeculectomy group and 40.61±7.85 mmHg in the AGV group before the treatment; 14.99±4.55 mmHg and 15.09±4.38 mmHg respectively in the 12th month (p=0.53). Surgical success rate was 73% in trabeculectomy group, 65% in AGV group (p=0.32). There were shallow anterior chamber in 4 (20%) patients in the trabeculectomy group, 4(20%) had hyphema, 3(15%) had hypotonia, 3(15%) had cataract, 2(10%) had vitreous hemorrhage, 1(5%) had choroidal detachment, 1(5%) had retinal detachment, 1(5%) had blebitis-induced endophthalmitis. 4(20%) patients in the AGV group had encapsulated bleb, 3(15%) had shallow anterior chamber, 2(10%) had hypotonia, 2(10%) had hyphema, 1(5%) had corneal oedema. Conclusion: There was no statistically significant difference between trabeculectomy with MMC and AGV implantation in patients with NVG. As a result, both surgeries can be preferred as a primary procedure. [ABSTRACT FROM AUTHOR]

Coexistence of cataract and glaucoma disease increases with an increase in life expectancy and includes anatomic and functional changes that may lead to intraocular pressure changes. Planned phacoemulsification surgery in patients with ocular hypertension, open-angle glaucoma, angle-closure glaucoma, antiglaucomatous drug therapy or glaucoma surgery needs to reorganise the antiglaucomatous treatment before, during and after surgery. In this review, intraocular pressure changes brought by cataract surgery in patients with glaucoma, physiopathology of these changes, antiglaucomatous treatment planning after cataract surgery, ocular surface changes and how glaucoma progression follow-up were investigated.

Objective: The aim of this study was to evaluate the efficacy and safety of trabeculectomy performed with mitomycin C (MMC) at a concentration of 0.2 mg/mL for 3 minutes in glaucoma patients with high risk of surgical failure. Methods: Forty-seven eyes of 45 patients (30 male, 15 female) undergoing glaucoma filtration surgery using MMC were retrospectively reviewed. All patients who had chronic closed angle, neovascular, aphakic, pseudophakic, pseudoexfoliation glaucoma and glaucoma after keratoplasty had a high risk of surgical failure. During standard trabeculectomy, triangular sponges impregnated with MMC at a concentration of 0.2 mg/mL were applied to tenon and episcleral space in sub-conjunctival regions and under the scleral flap for 3 minutes. Postoperative IOP, appearance of filtration bleb, anterior chamber depth, leakage detected with Seidel test and other complications were recorded. The patients were evaluated on the 1st day, 1st week, 1st month, 3rd month, 6th month and 12th month. Results: The mean preoperative IOP values of patients with a mean age of 64.5 (7-83 years) were 31.6 mmHg (17-60 mmHg). Mean postoperative IOP values of patients were 15.08 mmHg at 1st week, 15.32 mmHg at 1st month, 15.57 mmHg at 3rd month, 16.42 mmHg at 6 months, 16.28 mmHg at 12 months, and 16.87 mmHg at the last follow-up. Conclusion: For eyes with high risk of surgical failure, trabeculectomy performed with MMC at low dose and optimal time is an effective and reliable method with high success rate.

Purpose: To compare the short and the long term effects of momethasone and budesonid for the treatment of allergic rhinitis, on the intraocular pressure. Materials and Methods: Twenty fi ve patients were treated with momethasone furoate and 27 patients were treated with budesonid for 6 weeks. The mean follow-up time to evaluate the changes in the IOP was 50 days (38-60 days). Results: There was no difference between the groups with regard to age, gender and pretreatment IOP. Just after the treatment of allergic rhinitis and one month later, the IOPs were compared to pretreatment IOP's in both groups and no statistically significant differences were found. We also, compared the pretreatment, just after the treatment and one month later after the treatment IOP values between the groups; and no statistically significant differences were found (p<0.5). Conclusion: We concluded that the steroids used nasally as long as one month during allergic rhinitis did not cause to increase in the IOP. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the effect of intravitreal injection of ranibizumab, an anti-VEGF agent commonly used for the treatment of choroidal neovascularization, on optic nerve by pattern VEP test. Material and Method: Pattern VEP test was applied to 20 eyes of 20 patients who received 0.5 mg of ranibizumab injection because of age related choroidal neovascularization maculopathy and also to other non-injected eyes of the same patients in 1st and 6th weeks. Results are compared with 10 control patients of same age distribution. Results: Mean age was 73.45 in 20 age related maculopathy patients ranging between 64 and 82. Mean best corrected visual acuity of eyes receiving injection was 9/100 before injection and 14/100 finally on 6th week. Mean intraocular pressure was 13.85mmHg in eyes receiving before the injection, 16.75mmHg at 1st week and finally 14mmHg at 6th week. There was no statistically significant difference between the VEP wavelengths and latencies of the patient group and the control group (p> 0.05). There was no statistically significant difference between VEP wavelengths and latencies in 1st and 6th weeks between injection receiving eyes and the other eyes (p> 0.05). Conclusion: As a result of VEP evaluation it is concluded that 0.5 mg intravitreal ranibizumab injection does not have an indirect toxic effect to the optic nerve. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the postoperative anatomical and functional success status, postoperative complications and their results of vitreoretinal surgery (VRC) with the preference of vitreon use as a vitreoretinal (VR) tamponade for inferior rhegmatogenous retinal detachment (RRD). Methods: Forty-three eyes of 43 patients were retrospectively evaluated. Patients’ etiology of retinal detachment, preoperative ocular diseases, best corrected visual acuity (BCVA), intraocular pressure (IOP) values, biomicroscopic features, detailed fundus examination findings, postoperative complications, anatomical and functional success results were evaluated. Results: Twenty six of the 43 cases were male (62,8%) and 17 were female (37,2%). The mean age of the cases was 50.8±18.8. Ten (23.3%) patients had no predisposing factor for RRD, whereas the most common cause was pseudophakia (13 patients - 30.2%). In the postoperative period, visual acuity (VA) was increased in 20 patients and the initial VA was preserved in 13 patients. In 10 patients, visual acuity was worse than preoperative VA. After removal of the vitreon, the recurrence rate was %39.5. Postoperative anatomical success rate was 60,5%, and functional success rate was 76,7%. The most common postoperative complication was secondary cataract (23,3%). Conclusion: Vitreon should not be considered primary as an intravitreal tamponade in the case of for inferior rhegmatogenous retinal detachment due to various complications in the postoperative period and the high recurrence rates.

Purpose: To compare the measurements of intraocular pressures (IOP) by Corvis Scheimpflug Technology (CST), Air-puff Tonometry (AT) and Goldmann Aplanation Tonometry (GAT) in the eyes with different refractive errors, axial length and corneal thickness. Materials and Methods: Forty-six eyes of 10 healthy male and 13 healthy female volunteers with a mean age of 31.52 ± 7.36 were enrolled. Observations were made with CST, AT and GAT with 30 min intervals, and the average of these measurements was taken for 3 times. Results: The mean of measurements were found for refraction spherical equivalent -1.07 ± 1.04 (-3.5 to 1.25), for axial lengths 24.17 ± 1.23 (22.63-27.99), and for corneal thickness 552.74 ± 25.5 (510-623), respectively. In these 46 eyes IOP values were measured 17,15 ± 2,79 mmHg by AT; 15.82 ± 2.66 mmHg by GAT; 15.69 ± 2.39 mmHg by CST, respectively. IOP values measured in all devices were found to be compatible with each other. Central corneal thickness (CCT) was the main determinant of different measurements among the devices. Conclusion: The CST instrument is a reliable IOP measuring instrument with similar results to GAT, which is the gold standard method for tonometric measurements. [ABSTRACT FROM AUTHOR]
