Abstract
PURPOSE To compare superficial and deep vascular characteristics of the optic disc in retrobulbar optic neuritis using optical coherence tomography angiography (OCT-A). METHODS Nineteen patients with unilateral non-infectious retrobulbar neuritis were included in the study. The contralateral eyes of each patient were served as controls. OCT-A scans of the optic discs were performed in a 4.5 × 4.5 mm rectangular area, while macular OCT-A scans were performed in a 6 × 6 mm rectangular area. Various parameters, including radial peripapillary capillary (RPC) density, peripapillary retinal nerve fibre layer (pRNFL) thickness, cup volume, rim area, disc area, cup-to-disc (c/d) area ratio, and vertical and horizontal c/d ratios were automatically obtained using the instrument software. The density for superficial capillary plexus (SCP) and deep capillary plexus (DCP) were assessed using macular OCT-A. Parapapillary choroidal microvascular (PPCMv) density was calculated using MATLAB software. RESULTS Parafoveal inferior, perifoveal total and inferior SCP densities were significantly decreased in eyes with optic neuritis when compared with contralateral control eyes in OCT-A measurements (respectively, p = 0.027, p = 0.041, p = 0.045). The axial lengths, (p = 0.72), vertical and horizontal cup-disc ratios, and disc area, cup-disc areas, cup volumes, and pRNFL thicknesses between the groups were similar (for each, p>0.05). CONCLUSIONS This study demonstrated for the first time that patients with retrobulbar optic neuritis had decreased SCP densities, though it did not cause any changes in PPCMv density.

Abstract
OBJECTIVE To evaluate optic nerve head changes in patients with thyroid orbitopathy (TO) and investigate the effects of intravenous methylprednisolone (IV MTP) on these changes. METHODS Eighty-two eyes of 41 patients with TO with and without dysthyroid optic neuropathy (DON) and 40 eyes of 40 healthy control subjects were included in the study. Lamina cribrosa thickness (LCT) and depth (LCD) measurements, peripapillary retinal nerve fibre layer thickness (RNFLT), and radial peripapillary capillary vascular density were measured using optical coherence tomography and optical coherence tomography angiography. Visual field examination and proptosis were evaluated. Patients with DON and active non-DON received IV MTP for 12 weeks, and the effect of this treatment was evaluated. RESULTS Peripapillary vascular density decreased in patients with DON compared with the other groups (p < 0.001 for all); there was no difference in the total, superior hemi-sector, and inferior hemi-sector of the RNFLT between the groups. LCT was decreased in the TO group (p < 0.001). After IV MTP treatment, the LCT and best-corrected visual acuity were increased. Thyroid-stimulating hormone receptor antibody levels, intraocular pressure, the superior hemi-sector of the RNFLT, and proptosis were decreased compared with the control subjects (p = 0.012, p = 0.008, p = 0.043, and p < 0.001, respectively). CONCLUSIONS The RNFLT may not always increase in DON. Lamina cribrosa morphology may change in patients with TO. IV MTP therapy has a positive effect on the LCT but not on radial peripapillary capillary vascular density or LCD.

Abstract
PURPOSE The purpose of the study was to investigate the parapapillary choroidal microvasculature in thyroid eye disease (TED) using optical coherence tomography angiography (OCTA). METHODS Only one eye of each subject was included in the study. Patients with TED and controls were included in the study. Participants were divided into three groups: control, inactive TED (ITED) and active TED (ATED). OCTA scans of the optic discs were obtained in a 4.5 × 4.5-mm rectangular area. Radial peripapillary capillary (RPC) density and peripapillary retinal nerve fibre layer (pRNFL) thickness were automatically calculated by the device software. Parapapillary choroidal microvasculature (PPCMv) density was automatically calculated using MATLAB software. RESULTS Forty-one patients with TED and 40 controls were included in the study. RPC density was significantly decreased in the ATED and dysthyroid optic neuropathy (DON) group compared to the controls and ITED group. There was significant increase in pRNFL in the ATED group. PPCMv density increased in the ATED group compared to the controls in whole ring area. The RPC density was significantly correlated with the TSHr Ab level (r < - 0.396, p < 0.001). Clinical activity score correlated positively with PPCMv density (r = 0.349, p = 0.001) but negatively with RPC density (r = - 0.321, p = 0.004). CONCLUSION Changes in peripapillary microvascular perfusion may play a role in the development of DON. As the severity of TED increases with clinical activity, so do the changes observed in peripapillary parameters. The decrease in RPC density may be due to compression caused by optic disc oedema, which may result in reduced blood flow. The increase in PPCMv density may be related to factors such as orbital congestion.

Abstract
INTRODUCTION Polyarteritis nodosa is a systemic vasculitis characterized by necrotizing inflammatory lesions affecting the middle and small arteries. CASE PRESENTATION A 23-year-old male presented to our ophthalmology clinic with a 1-day history of sudden vision loss in his left eye. Posterior segment examination the left eye showed optic disc borders were faint, hyperemic and fluffy with cilioretinal artery occlusion signs present. Optical coherence tomography revealed the presence of localized intracellular edema from optic disc to superior-hemi of fovea, including fovea. On optical coherence tomography angiography, there was a decrease in vessel density in the superficial and deep capillary plexus in the area matching the cilioretinal artery trace, and choroidal vessel density decreased. Wide field fundus fluorescein angiography showed a large choroidal filling defect (ischemia area) and the cilioretinal artery were not filled in the temporal quadrant. These findings made us think that short ciliary arteries were affected and were the causal of the choroidal ischemia and infarction of optic nerve. DISCUSSION PAN-associated choroidal ischemia, cilioretinal artery occlusion and ischemic optic neuropathy are rare. If ischemic retinal condition is seen in young patients, PAN should be considered in the differential diagnosis as it may cause life-threatening complications in its advanced stages.

Abstract
AIM The aim was to compare the pathological complete response (pCR) rate at 8 compared to 12 weeks' interval between completion of neoadjuvant chemoradiotherapy (CRT) and surgery in patients with locally advanced rectal cancer. METHOD This was a randomized trial which included a total of 330 patients from two institutions. Patients with locally advanced (T3-4N0M0, TxN+M0) rectal cancer were randomized into 8- and 12-week interval groups. All the patients received long-course CRT (45 Gy in 1.8 Gy fractions and concomitant oral capecitabine or 5-fluorouracil infusion). Surgery was performed at either 8 or 12 weeks after CRT. The primary end-point was pCR. Secondary end-points were sphincter preservation, postoperative morbidity and mortality. RESULTS Two-hundred and fifty-two patients (n = 125 in the 8-week group, n = 127 in the 12-week group) were included. Demographic and clinical characteristics were similar between groups. The overall pCR rate was 17.9% (n = 45): 12% (n = 15) in the 8-week group and 23.6% (n = 30) in the 12-week group (P = 0.021). Sphincter-preserving surgery was performed in 107 (85.6%) patients which was significantly higher than the 94 (74%) patients in the 12-week group (P = 0.016). Postoperative mortality was seen in three (1.2%) patients overall and was not different between groups (1.6% in 8 weeks vs 0.8% in 12 weeks, P = 0.494). Groups were similar in anastomotic leak (10.8% in 8 weeks vs 4.5% in 12 weeks, P = 0.088) and morbidity (30.4% in 8 weeks and 20.1% in 12 weeks, P = 0.083). CONCLUSION Extending the interval between CRT and surgery from 8 to 12 weeks resulted in a 2-fold increase in pCR rate without any difference in mortality and morbidity.

Abstract
This prospective clinical case series aimed to investigate the safety and efficacy of suprachoroidal adipose tissue-derived mesenchymal stem cell (ADMSC) implantation in patients with dry-type age-related macular degeneration (AMD) and Stargardt's macular dystrophy (SMD). This study included four patients with advanced-stage dry-type AMD and four patients with SMD who underwent suprachoroidal implantation of ADMSCs. The best-corrected visual acuity (BCVA) in the study was 20/200. The worse eye of the patient was operated on. Patients were evaluated on the first day, first week, and first, third, and sixth months postoperatively. BCVA, anterior segment and fundus examination, color photography, fundus autofluorescence, optical coherence tomography, and visual field examination were carried out at each visit. Fundus fluorescein angiography and multifocal electroretinography (mf-ERG) recordings were performed at the end of the first, third, and sixth months and anytime if necessary during the follow-up. All eight patients completed the sixth month follow-up. None of them had any systemic or ocular complications. All of the eight patients experienced visual acuity improvement, visual field improvement, and improvement in mf-ERG recordings. Stem cell treatment with suprachoroidal implantation of ADMSCs seems to be safe and effective in the treatment of dry-type AMD and SMD.

Abstract
A 25-year-old woman underwent diode laser application on the both upper eyelids in the dermatology department of a private hospital to obtain a cosmetic healing of the reddish look on her eyelids without any protective lenses. The patient experienced severe uveitis, atonic pupils, raised intraocular pressure, and increased sensitivity to light in her eyes on the following day of the procedure. Topical steroids and pressure-lowering agents were able to treat the acute uveitis and glaucoma, unfortunately the patient suffered from irreversible atonic and atrophic pupils and photosensitivity. It is recommended that cosmetic laser application on the periocular area should be avoided, and if it is still to be performed, it should be applied cautiously and the patient should be informed of the potential ocular complications.

Abstract
PURPOSE There have been ongoing clinical trials of therapeutic agents in Huntington's disease (HD) which requires development of reliable biomarkers of disease progression. There have been studies in the literature with conflicting results on the involvement of retina in HD, and up to date there is not a study evaluating the single retinal layers in HD. We aimed to evaluate the specific retinal changes in HD and their usability as potential disease progression markers. METHODS This cross-sectional study used spectral-domain optical coherence tomography with automatic segmentation to measure peripapillary retinal nerve fiber layer (pRNFL) thickness and the thickness and volume of retinal layers in foveal scans of 15 patients with HD and 15 age- and sex-matched controls. Genetic testing results, disease duration, HD disease burden scores and Unified HD Rating Scales motor scores were acquired for the patients. RESULTS Temporal pRNFL, macular RNFL (mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer and outer plexiform layer thicknesses and IPL, retinal pigment epithelium and outer macular volume were found lower in HD compared to controls, while outer nuclear layer and outer retinal layer thickness were increased (p < 0.05). We found significant correlations between inner retinal layer thicknesses, most significantly with mRNFL and GCL and disease progression markers. CONCLUSION The outcomes of this study points out that retinal layers, most significantly mRNFL and GCL, are strongly correlated with the disease progression in HD and could serve as useful biomarkers for disease progression.

Abstract
To assess the correlation between functional and anatomical evaluations with multifocal electroretinography (mfERG) and spectral-domain optical coherence tomography (SD-OCT) in patients with Parkinson's disease (PD). This cross-sectional study involved 116 eyes of 58 patients with PD and 30 age- and sex-matched control subjects. All study participants underwent a comprehensive neuro-ophthalmic examination, retinal single-layer thicknesses and volumes, and peripapillary retinal nerve fiber layer (pRNFL) measurements with SD-OCT, and the patients' mfERG recordings were evaluated. The macular retinal nerve fiber layer (mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), outer nuclear layer (ONL), retinal pigment epithelium (RPE), and photoreceptor layer (PR) thicknesses, and mRNFL, RPE, and PR volumes were found lower in PD compared to those of controls, while outer plexiform layer (OPL) volumes were increased (p < 0.05). We found delayed implicit times and decreased amplitudes in the mfERG of PD patients versus those in control subjects (p < 0.05). We found significant correlations between outer macular volumes, PR thicknesses, and N1 amplitudes of rings 2 and 3and P1 amplitudes of rings 3, 4, and 5. Our study revealed thinning of both inner and outer retinal single layers, increased OPL volume, and delayed implicit times and decreased amplitudes in the mfERG of PD patients versus control subjects and correlation between structural and functional parameters. Our findings point out that SD-OCT and mfERG could both serve as non-invasive tools for evaluating ophthalmic manifestations of Parkinson's disease.

Abstract
BACKGROUND The aim of the study is to test whether use of autologous serum eye-drops can provide earlier epithelial healing following the application of photorefractive keratectomy. METHOD Sixty patients (60 eyes) underwent photorefractive keratectomy for myopia. Thirty eyes received autologous serum drops (Study group) while 30 eyes received conventional artificial tears (Control group) after photorefractive keratectomy. An 8 mm epithelial opening was prepared with the application of 18 per cent alcohol for 20 seconds. Photorefractive keratectomy was performed using ESIRIS excimer laser (SCHWIND, Kleinostheim, Germany) with an optic zone of 6.5 mm. Total duration of epithelial healing was monitored as the main outcome measure. The comparisons were done with chi-square test and independent samples t-test. Statistical significance was considered at p < 0.05. RESULTS Preoperative myopic spherical refraction and ablation depths were similar in the study and control groups. The mean duration for epithelial healing was about one day shorter in the eyes receiving autologous serum compared to the eyes receiving conventional treatment (2.2 ± 0.25 days versus 3 ± 0 days, p = 0.001). All eyes achieved 6/7.5 or better uncorrected visual acuity in six months. In both groups, more than 90 per cent of eyes were within ±0.50 D of emmetropia in 12 months. No significant difference was noted for the incidence of +1 haze. CONCLUSION Use of autologous serum drops reduces epithelial healing duration following surface ablation for two days.

Abstract
AIM To evaluate the retinal vessel diameters in patients with migraine by optical coherence tomography (OCT). METHODS In this cross-sectional study, 124 eyes of 62 patients with a diagnosis of unilateral migraine during attack-free period and 42 age- and sex-matched control subjects were included. Migraine patients were divided into the ≤2 migraine attacks per month group and the ≥5 migraine attacks per month group. All subjects underwent complete ophthalmological and neurological examinations before measurements. Retinal vessel diameters and choroidal thickness were examined with the Spectralis OCT. RESULTS The mean diameters of the arteries in the eyes on the headache side of control group, ≥5 migraine attacks per month and ≤2 migraine attacks per month group at 480 µm from the optic disk (Raster 3) were 119.54±46.69, 136.68±25.93 and 119.34±31.75 µm respectively with a steady decline to 105.57±32.15, 118.18±31.87 and 108.05±38.77 µm at 1440 µm (Raster 7), the last measurement point, respectively. The retinal artery diameter measurements were significantly increased in ≥5 migraine attacks per month patients at four out of five measured points compared to control group (P<0.05). There were no statistical differences at any of the points of vein measurements. The choroidal thickness measurements were significantly decreased in ≥5 migraine attacks per month patients at all measured points compared to control group (P<0.05). CONCLUSION The retinal artery diameter is found to increase significantly and the choroidal thickness is found to decrease in the eyes on the headache side in ≥5 migraine attacks per month patients compared to control group.

Abstract
PURPOSE To evaluate the effect of fluorescein angiography on retinal vessel diameter with Optical Coherence Tomography (OCT). METHODS In this cross-sectional study, a total of 81 eyes of 81 patients who were performed fluorescein angiography (FA) procedure were included. Retinal vessels were examined with the Spectral-domain OCT at baseline and immediately after FA procedure. A cube scan consisting of seven horizontal scans were placed at the inferior border of the disk to include the inferior temporal retinal vessels. Vessels diameters were measured at five measurement points (480-1440 μm inferiorly from the optic disk border). RESULTS The mean age of the study subjects was 58.02 ± 14.1 years. At baseline, the mean diameter of the retinal artery was 120.16 ± 24.56 µm and of the vein 157.94 ± 32.34 µm at the measurement point of 480 μm, with a gradual decrease to 114.91 ± 25.59 and 152.17 ± 28.17 µm, respectively, at 1440 μm. After FA procedure, the mean diameter of the retinal artery was 122.85 ± 26.35 and of the vein 158.30 ± 32.21 µm at the measurement point of 480 μm, with a gradual decrease to 115.22 ± 22.91 and 151.94 ± 28.93 µm, respectively, at 1440 μm. There were no statistical differences for either of these comparisons at any of the points of both artery and vein measurements. CONCLUSION There was not any clinically significant change in retinal artery diameter such as a dilatatory response after FA procedure in patients with hypertension, diabetes, and age-related macular degeneration (AMD).

Abstract
SETTING Lung cancer and pulmonary tuberculosis (TB) comorbidity is a clinical problem that presents a challenge for the diagnosis and treatment of both diseases. OBJECTIVE To clarify the clinical and survival characteristics of cases with both lung cancer and active pulmonary TB. DESIGN From 2008 to 2013, 3350 TB patients admitted to the TB Department of the Chest Diseases Hospital of Izmir, Turkey, were evaluated. RESULTS In 38 (1.1%) male patients, lung cancer and TB were found to coexist. Almost all of the patients were diagnosed at Stage III (n = 14, 36.8%) or IV (n = 17, 44.7%) lung cancer, whereas four (10.6%) had Stage II and three (7.9%) had Stage I disease. Squamous cell lung cancer was the predominant histology (n = 23, 60.7%). The median overall survival among patients was 13.4 months (95%CI 8.09-18.8). One-year survival rates for patients with Stages I, II, III and IV were respectively 100%, 75%, 57% and 40%. CONCLUSION The present study demonstrates that lung cancer combined with active pulmonary TB most frequently presents as squamous cell carcinoma, with a male predominance. The overall survival of lung cancer patients did not change even with concomitant active TB.

Abstract
AIM To evaluate the neuroprotective effect of rosuvastatin, in a rat experimental glaucoma model. METHODS Ocular hypertension was induced in right eyes of Long-Evans rats (n=30) by cauterization of three episcleral veins. Left eyes were defined as controls. Rats were divided into five groups: oral rosuvastatin, intravitreal rosuvastatin, oral+intravitreal rosuvastatin, intravitreal sham and glaucoma without intervention. Rats were sacrificed at day 14. Retinal ganglion cell (RGC) number was assessed by histopathological analysis. Terminal deoxynucleotidyl transferase-mediated dUTP-nick end-labeling (TUNEL) staining and the expression of glial fibrillary acidic protein (GFAP) in RGC layer was also examined. RESULTS A significant intraocular pressure (IOP) elevation was seen (P=0.002). Elevated IOP resulted in a significant decrease in number of RGCs in group 5 (70.33±8.2 cells/mm(2)) when compared with controls (92.50±13.72 cells/mm(2); P=0.03). The RGC number in group 1 (92.4±7.3 cells/mm(2)) was significantly higher than group 5 (P=0.03). The numbers of RGC in groups 2, 3 (57.3±8.2 cells/mm(2), 60.5±12.9 cells/mm(2)) were comparable with that of group 5 (P=0.18 and P=0.31). The apoptosis rates with TUNEL staining were also parallel to RGC number. Animals with experimentally induced glaucoma showed an increase in retinal GFAP immunoreactivity. CONCLUSION Decrease in RGC loss and apoptosis suggest the neuroprotective potential of oral rosuvastatin treatment in a rat model of ocular hypertension. However intravitreal rosuvastatin showed a contrary effect and further studies are required.

Abstract
INTRODUCTION ST segment elevation myocardial infarction (STEMI) due to coronary artery occlusion caused by intracoronary thrombosis in the setting of acute carbon monoxide (CO) poisoning is a very rare presentation. We present a case of intracoronary large and mobile thrombus formation after CO poisoning. CASE PRESENTATION A previously healthy 50-year-old woman was referred for CO poisoning. She had chest pain after exposure to CO. Her initial mental status was preoccupied with chest pain. Her initial CO fraction was 28.1%, and initial laboratory data showed creatine kinase-myocardial isoenzyme of 134 U/L (upper limit 25 U/L) and troponin I of >50 ng/mL (upper limit 0.06 ng/mL). Electrocardiography was carried out on admission, revealing an ST segment elevation in the inferolateral leads. After initial evaluation, coronary angiography was performed and an intracoronary large mobile thrombus was seen in the proximal left anterior descending (LAD) artery with no significant stenosis. We administered tenecteplase with heparin. After the thrombolytic therapy, ST elevation in the inferolateral leads resolved. Repeat angiography was performed after 24 h; the thrombus in LAD had resolved. The patient was discharged after 5 days, with persistent Q wave in the inferior leads and mild hypokinesia of the inferoposterior wall suggesting myocardial injury. CONCLUSION We describe intracoronary thrombus formation induced by CO poisoning. Because intracoronary thrombus can result in myocardial infarction, its consideration following CO poisoning is important. Patients with CO poisoning who have symptoms of STEMI should be carefully evaluated with serial electrocardiograms, cardiac biomarkers, and an echocardiogram. When there is evidence of acute myocardial injury, a primer in coronary angiography can determine which patients could benefit from intervention.

Abstract
Active tuning and switching of electromagnetic properties of materials is of great importance for controlling their interaction with electromagnetic waves. In spite of their great promise, previously demonstrated reconfigurable metamaterials are limited in their operation bandwidth due to their resonant nature. Here, we demonstrate a new class of meta-surfaces that exhibit electrically-induced switching in their scattering parameters at room temperature and over a broad range of frequencies. Structural configuration of the subwavelength meta-molecules determines their electromagnetic response to an incident electromagnetic radiation. By reconfiguration of the meta-molecule structure, the strength of the induced electric field and magnetic field in the opposite direction to the incident fields are varied and the scattering parameters of the meta-surface are altered, consequently. We demonstrate a custom-designed meta-surface with switchable scattering parameters at a broad range of terahertz frequencies, enabling terahertz intensity modulation with record high modulation depths and modulation bandwidths through a fully integrated, voltage-controlled device platform at room temperature.

Abstract
We report on a patient with Frank-Ter Haar syndrome that is associated with high intraocular pressures. A 21-day-old male patient was referred to our clinic for surgical treatment of congenital glaucoma. On ophthalmic examination, he had buphthalmos, mild corneal edema and high IOP readings in both eyes. The patient underwent uneventful trabeculotomy surgery, bilaterally. Marked bilateral anterior iris insertion was noted during the surgery. Childhood glaucoma may be associated with Frank-Ter Haar syndrome.
