RESUMO

OBJECTIVES: Endoscopic balloon dilatation (EBD) offers a safe and non-invasive surgical option for the treatment of subglottic stenosis. Patient selection is important to achieve good results and to detect which patients are more prone to the development of complications. The aim of this study was to determine predictors of postoperative problems and early complications in primary EBD surgeries. METHODS: A retrospective analysis was made of patients with acquired subglottic stenosis who were operated on with the EBD technique between January 2010 and December 2019 in the Otolaryngology-Head and Neck Surgery Department of Baskent University Hospital. Demographic data including the age and sex of the patients were collected together with etiology, presence of chromosomal or craniofacial anomaly (C/CA), duration of prolonged intubation (DPI), and extubation dilatation timeframe (EDT). Intra and postoperative follow-up data were recorded of the need for intubation or tracheotomy, development of desaturation, and grade and type of stenosis. RESULTS: The male to female ratio was 2:1. The patients comprised 42 males and 22 females with a mean age of 296.52 ± 551.93 days. The cause of prolonged intubation was surgery for congenital heart disease in 50 (78.1%) patients and prematurity in 14 (21.9%). The type of lesion was acute granulation in 44 (72.1%) and chronic granulation in 17 (27.9%) patients. C/CA was determined in 13 patients, the mean grade of stenosis was 76.33 ± 15.21%, mean DPI was 25.25 ± 35.49 days, and mean EDT was calculated as 78.23 ± 373.82 days. Desaturation following endoscopic balloon dilatation developed in 26 (40.6%), orotracheal intubation was required in 10 (15.6%), tracheotomy in 10 (15.6%), and cardiopulmonary arrest occurred in 4 (6.25%). Prematurity, a longer duration of preoperative intubation, longer time from extubation to dilatation, older age, and higher grade of stenosis were determined as factors associated with postoperative early respiratory complications. CONCLUSION: EBD indication should be carefully considered in children with acquired subglottic stenosis. To achieve better results and minimise complications, EBD should be performed without delay.

RESUMO

PURPOSE: To compare retinal nerve fiber layer (RNFL) thickness and ganglion cell-inner plexiform layer thickness (GCIPLT) in the affected eyes to fellow unaffected eyes of patients with unilateral Fuchs' uveitis syndrome (FUS) and analyze their change over time. METHODS: Twenty seven unilateral FUS patients who did not have concomitant systemic or ocular disease were retrospectively enrolled. Central macular thickness (CMT), RNFL thickness, and GCIPLT measurements were evaluated. Data was analyzed using the non-parametric Brunner-Langer model (LD-F2 design) and Wilcoxon signed-rank test. RESULTS: The mean age of the patients was 40.2 ± 10.2 years. The median disease duration was 11 (2-62) months. The median best-corrected visual acuity (BCVA) of the affected eyes and the fellow eyes was 0.22 (0.00-2.50) vs. 0.00 (0.0-0.10) logMAR at the initial visit and 0.05 (0.00-2.50) vs. 0.00 (0.0-0.30) logMAR at the final visit. The change in BCVA was found significant in the affected eyes, but not in the fellow eyes (p < 0.001 and p = 0.287, respectively). The median CMT in the affected eyes at the final visit was not statistically different from the value at the initial visit (255 (157-306) vs. 245 (140-310) µm, p = 0.256). The change in RNFL thickness over time in the affected eyes was similar to the fellow unaffected eyes of the patients with unilateral FUS at all quadrants, with non-significant time and group effects (p > 0.05). However, median GCIPLT in all quadrants (except superonasal) in the affected eyes was statistically lower than the fellow eyes at the initial and final visits (p < 0.05). The most affected quadrant of the ganglion cell complex was inferonasal in the involved eyes (79 (42-97) vs. 75 (43-87) µm) at initial and final visits (p = 0.033 for time effect and p < 0.001 for group effect, respectively). CONCLUSION: Median CMT and RNFL thickness did not change during follow-up in the affected eyes of patients with unilateral FUS. Median GCIPLT in the affected eyes declined over time in all quadrants. Ganglion cell loss was also most prominent in the inferonasal quadrant in the affected eyes. FUS patients should be followed up long-term in terms of ganglion cell loss, especially in the inferonasal quadrant.

RESUMO

BACKGROUND: The integration of anatomical and nonanatomical parameters will improve our ability to predict the outcomes of OSA treatment. Currently, no standardized, quantitative classification of upper airway anatomical traits is available. The retropalatal (RP) airway is the most important area to consider when planning anatomical treatment. However, current evaluation methods feature qualitative conventional endoscopy. Here, we describe a quantitative magnetic resonance imaging (MRI) method used to classify RP airway patterns. METHODS: We recruited 117 males; 20 simple snorers and 97 patients with OSA. Lateral/anteroposterior ratios were calculated in three parallel planes and RP patterns were classified accordingly. Lateral wall soft tissue structures, skeletal dimensions representing those planes, pharyngeal lengths, and skeletal and vertical axis ratios were also measured. RESULTS: Both the cross-sectional area at the hard palate level and the RP lateral dimension were associated with OSA. OSA patients had longer pharynges than controls. The oblique pattern was associated with narrow lateral dimensions. The vertical pattern was associated with a narrow nasopharynx but a longer pharynx. The airway ratio at the hard palate level and the skeletal ratios of all three planes were negatively correlated with the vertical axis ratio and together explained 40.8% of the variance in the vertical axis ratio. CONCLUSIONS: The data suggest that anatomical imbalances between the craniofacial skeletal and soft tissue structures affect pharyngeal airway morphology in all three dimensions. The dimensions of the nasopharynx, the cross-sectional area at the hard palate level, and pharyngeal length were associated not only with the RP patterns but also with OSA severity. This study affords insights into upper airway anatomy and RP patterns and may help diagnose OSA patients and aid in the selection of an appropriate therapy.

RESUMO

OBJECTIVES: Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Radioactive iodine (RAI) therapy is used for remnant ablation following thyroidectomy. Side effects such as dysphagia, xerostomia, and sialoadenitis may occur. We aimed to determine the differences in the parotid and submandibulary glands between healthy patients and patients with PTC who had undergone RAI therapy and have dry mouth symptoms using both shear wave elastography and ultrasonography. METHODS: We enrolled 30 patients with PTC who had undergone RAI therapy following surgery and 30 healthy controls. Ultrasonography and shear wave elastography of submandibular and parotid glands were performed. The volume of the submandibular glands and the thickness of parotid glands were determined. Ten independent measurements were obtained from each gland, with the region of interest placed at different points on the glands. The mean shear wave velocities (SWVs) were calculated and compared between the patients and controls. RESULTS: In the PTC group, there was a significant reduction in the volume of the submandibular glands (P < .05) and in the thickness of the parotid glands (P < .05) compared with the control group. The mean SWVs of the parotid glands and submandibular glands were significantly higher in the PTC group compared with the control group (P < .0001). The SWVs of the parotid glands were higher than the SWVs of the submandibular glands (P < .0001). CONCLUSIONS: Shear wave elastography could be a noninvasive and easy assessment method of parotid and submandibular glands in patients who had undergone RAI therapy and experience dry mouth.

RESUMO

The purpose of this study was to describe a patient of orbital apex syndrome, anterior uveitis, secondary glaucoma, corneal dellen, and necrotizing scleritis following an attack of herpes zoster ophthalmicus, and the placement of a pericardial patch graft. A 64-year-old male patient with blepharoptosis of his right eye and multiple vesicles on the forehead, nose and cheeks, limitation on all gazes, blepharoptosis, and exophthalmia was eventually diagnosed with ophthalmic zona with orbital apex syndrome. After the treatment with systemic antiviral and steroid, there was complete recovery of the unilateral vesicular eruption, ophthalmoplegia, and ptosis at the third month follow-up. However, anterior uveitis, necrotizing scleritis, secondary glaucoma, and corneal dellen developed during follow-up. At the ninth month, pericardial patch graft (Tutoplast) was placed due to progression of the scleral thinning. Graft vascularization was completed. Careful and long-term follow-up of patients with ophthalmic zona is required for possible ophthalmic complications of varicella zoster virus infections. A pericardial patch graft might be placed due to the development of necrotizing scleritis.

RESUMO

PURPOSE: To compare normal male and female craniofacial parameters in adults and evaluate associations of sex and intercochlear distance with other craniofacial parameters. METHODS: In 60 normal adults (30 men and 30 women) who had no otitis media, craniofacial parameters were measured retrospectively on two-dimensional reformatted computed tomography scans. RESULTS: Compared with women, men had significantly greater mean osseous auditory tube length, cartilaginous auditory tube length, mastoid length, intercochlear distance, sella to posterior nasal spine distance, sella to basion distance, and nasopharynx sagittal area. The intercochlear distance was significantly correlated with mastoid depth, midpoint of the pharyngeal opening distance, sella to nasion distance, and nasopharynx sagittal area and inversely with angle of the auditory tube. Most men and women had Körner septum present, and mean thickness of Körner septum was significantly greater in men than women. CONCLUSIONS: Some craniofacial parameters, especially vertical parameters, differ with sex. These differences begin in childhood and continue in adulthood. Sex must be considered when planning a craniofacial morphologic study, and results of a craniofacial morphologic study should be evaluated with caution when there is no sex matching of the patient and control groups.

RESUMO

OBJECTIVES: This study aims to evaluate the alterations in distances to the surgical margins on sheep tongue specimens, through resection, formalin fixation, frozen section, and microscopic examination. MATERIALS AND METHODS: Fifty fresh sheep tongues were used in the study. A metal plate was fixed on the lateral aspect of each tongue to represent tumor tissues. A total of 40 specimens with either 1 cm or 2 cm distances as surgical safety margins of the surrounding plate were prepared using either scalpel or monopolar cautery (10 specimens were prepared for each group). Additional 10 specimens with 1 cm safety margins were prepared using either scalpel or monopolar cautery (5 specimens per group) for frozen section examination. Distances to the metal plates before resection were compared with the ones which were determined after resection, frozen section examination, 24-hour formalin fixation and microscopic examination. RESULTS: Distances to the surgical margins were found to be decreased in all specimens after resection, 10% formalin fixation and microscopic examination. The distances to the surgical margins were observed to be reduced by 6.5-7.5% on average after resection, 10-12% on average after formalin fixation and 30% on average after microscopic examination, compared to the baseline values. The level of shrinkage was reduced by 6.3-10% following microscopic section preparation during frozen section examination. CONCLUSION: Seven to eight-millimeter distance to the surgical margin at minimum should be maintained to achieve a 5 mm in height surgical safety margin during sheep tongue resection. The distance defined by the pathologist may be multiplied with 1.42 to estimate around in-situ distance to the surgical margins. Therefore, 1.42 may be used as a corrective factor for sheep tongue tissues.

RESUMO

Hemangiomas are the most common vascular tumors and von Willebrand disease is the most common inherited bleeding disorder. In this article, we report a 21-year-old female who had von Willebrand disease presenting with 1x1 cm lesion of the tongue. The lesion was located at the anterior one-third in midline tongue throughout full-thickness. The patient was administered cryoprecipitate preoperatively. Then the lesion was excised under local anesthesia. Histopathological examination revealed a hemangioma. No complication such as bleeding or infection after the operation was observed.

RESUMO

Objectives: This study aimed to compare the effects of dexamethasone (DEX) implants and ranibizumab (RAN) injections in younger patients with macular edema due to branch retinal vein occlusion (RVO) in a 6-month follow-up. Methods: The treatment-naive patients with macular edema secondary to branch RVO were included retrospectively. Medical records of patients who were treated with intravitreal RAN or DEX implant were evaluated before and at the 1st, 3rd, and 6th months after the injection. Primary outcome measures were the change in best-corrected visual acuity (BCVA) and central retinal thickness. The level of statistical significance was set at 0.05/3=0.016, according to the Bonferroni correction. Results: Thirty-nine eyes of 39 patients were included in the study. The mean age of the study population was 53.82±5.08 years. Median BCVA in the DEX group (n=23) at baseline, 1st, 3rd, and 6th month was 1.1, 0.80 (p=0.002), 0.70 (p=0.003), and 1 (p=0.018) logarithm of the minimum angle of resolution (log-MAR), respectively (p<0.05). Median BCVA in the RAN group (n=16) at baseline, 1st, 3rd, and 6th months was 0.90, 0.61, 0.52, and 0.46 logMAR, respectively (p<0.016 for all comparisons). Median central macular thickness (CMT) in the DEX group at baseline, 1st, 3rd, and 6th months was 515, 260, 248, and 367 µm, respectively (p<0.016 for all comparisons). Median CMT in the RAN group at baseline, 1st, 3rd, and 6th months was 432.5 (p<0.016), 275 (p<0.016), 246 (p<0.016), and 338 (p=0.148) µm. Conclusion: There is no significant difference in treatment efficacies in both visual and anatomical outcomes at the end of the 6th month. However, RAN can be considered the first choice in younger patients with macular edema secondary to branch RVO because of the lower side effect profile.

RESUMO

Cancer in pregnant women is a very difficult clinical condition that profoundly affects patients and their families, as well as the medical staff who provide their care. Diagnostic and therapeutic decisions must balance adequate treatment and fetal risk. In developed societies, cancer in pregnant women has become more common during the last 30 years because of an increase in the number of relatively older women who give birth. The most common malignancies in pregnant women are melanoma; lymphoma; leukemia; and breast, cervical, ovarian, gastrointestinal, and genitourinary cancers. Cancer of the head and neck in pregnant patients is very rare. In this article, we describe a rare case of advanced squamous cell carcinoma of the hypopharyngeal area in a young pregnant woman, and we discuss the diagnosis and treatment of cancers of the head and neck in pregnant patients.

RESUMO

We report a 38-year-old man who presented with a 7-year history of a mass in the right medial canthal region. He had several episodes of dacryocystitis, epiphora and bloody discharge. A cystic lesion was defined on MRI. Lacrimal sac excision was performed and a dark red mass was extirpated. External dacryocystorhinostomy and bicanalicular silicone tube intubation was performed. The polypoid lesion was diagnosed as an inflammatory polyp. Benign and malignant tumors of the lacrimal sac may have similar clinical findings on presentation. Preoperative ancillary testing may help us to have an idea of the nature of the lesion but histopathological examination is still the gold standard. Ophthalmologists should remember this similarity and be careful especially while performing endoscopic or laser-assisted dacryocystorhinostomy.

RESUMO

OBJECTIVES: In this study the relationship of serum homocysteine, vitamin B12, folic acid levels and peripheral vestibular dysfunction (PVD) was investigated. PATIENTS AND METHODS: Forty-one patients (31 females, 10 males; mean age 57.34±14.3 years; range 12 to 80 years) who admitted to Baskent University Hospital Ear Nose and Throat Department between the dates of April 2005 - December 2007 with complaint of vertigo were prospectively analyzed and diagnosed using audio-vestibular test, at the same time serum homocysteine, vitamin B12, folic acid measurements was done from the blood samples of patients. The patients were divided into three groups as Meniere's disease, vestibular neurinitis, and benign paroxismal positional vertigo (BPPV) according to the diagnoses and serum homocysteine, vitamin B12, folic acid levels of patients were compared to normal values in and between groups. RESULTS: Of the patients, 29.3% (n=12) were diagnosed with Meniere's disease, 36.6% (n=15) with vestibular neurinitis, and 34.1% (n=14) with BPPV. Serum homocysteine leves of patients were 12.42±3.56 umol/L, 11.32±4.14 umol/L and 10.72±2.95 umol/L (p>0.05) in Meniere's disease, vestibular neurinitis, and BPPV respectively; vitamin B12 levels were 371.58±141.35 pg/ml, 288.13±139.51 pg/ml, 352.14±150.41 pg/ml (p>0.05) respectively and folic acid levels were 8.76±3.2 umol/L, 10.63±6.59 umol/L, 8.8±3.18 umol/L (p>0.05) respectively. The values were similar in all patients. No statistically significant difference was found in and between groups comparing with normal values. CONCLUSION: This is the first prospective study investigating the relationship of serum homocystein, vitamin B12 and folic acid levels with PVD. We found that there is no relationship of homocysteine, vitamin B12, folic acid levels with PVD.

RESUMO

Antrochoanal polyp is a benign, solitary polypoid lesion arising from the edematous mucosa of the maxillary sinus and extending through the maxillary ostium into the nose. In children, it constitutes 33% of all nasal polyps. It presents most commonly with unilateral nasal obstruction and purulent rhinorrhea. Surgery is the usual treatment for antrochoanal polyps. The primary aim of treatment for antrochoanal polyp must be complete removal with total cleaning of the maxillary sinus. In this article, we present a case of a 13-year-old boy with an antrochoanal polyp who complained of difficulty in breathing and swallowing; the differential diagnosis of nasopharyngeal masses and the treatment of antrochoanal polyps in children are also discussed. Antrochoanal polyps present most commonly with unilateral nasal obstruction; however, they sometimes present atypically. Clinical manifestations may mimic other neoplasms in the nasal cavity and nasopharynx. Nasopharyngeal masses must be evaluated by endoscopic examination and radiologic imaging before surgery to avoid unnecessary and harmful surgical techniques. Reporting this case is important to direct attention of the Ear, Nose and Throat specialist and pediatricians when facing similar cases.

RESUMO

As the aerospace industry has grown rapidly over the years, aviators and astronauts have been exposed to some abnormal physiological changes arising from the dynamics of the aerospace environment. The vestibular system, encoding linear and angular movements of the head, is one of the main affected systems in which those abnormal changes can occur during flight. Despite the intricate and solid organization, vestibular units are such delicate structures that they can easily be deceived by aerial dynamics and gravity changes. Therefore, it is of vital importance for the continuity of flight safety to be aware of the detrimental alterations and impairments regarding the vestibular system and its reflex pathways. The aim of this paper was to present a review about how a healthy vestibular system is negatively affected within the aerospace environment and how some vestibular disorders become exaggerated or impaired during aviation and space activities.

RESUMO

BACKGROUND: Comparing the central choroidal thickness (CCT) and the perfusion of the macula and optic disk in patients with migraine and control group participants using optical coherence tomography angiography (OCTA). METHODS: A total of 38 patients diagnosed with migraine and 32 healthy controls were recruited. OCTA scans were performed on all participants. Optic disk, central macular vascular perfusions, and CCT were measured. RESULTS: Thirty-eight eyes of 38 participants (34 female and 4 male) in the migraine group and 32 eyes of 32 participants (19 female and 13 male) in the healthy control (HC) group were evaluated. The mean age was 42.74 ± 8.14 and 43.09 ± 14.28 years in the migraine group and HC group, respectively. The mean CCT were 314 ± 103 µm and 301 ± 71 µm in the migraine and HC group, respectively (p = 0.54). The mean optic disk perfusions were 44.77 ± 1.93% and 45.25 ± 1.43% in migraine and HC group, respectively (p = 0.25). The mean central macular vascular perfusions were 20.50 ± 8.20% and 18.65 ± 7.46% in migraine and HC group, respectively (p = 0.32). There was a significant negative correlation between CCT and the duration of migraine history (p = 0.004). CONCLUSIONS: The macular and peripapillary microvasculature were not significantly different in patients with migraine than in HC. As the duration of migraine prolonged, a significant decrease in choroidal thickness was observed.

RESUMO

We aimed to clarify the relation between allergic rhinitis and the serum levels of 25-hydroxivitamin D in the adult population. The study group consisted of 86 patients with allergic rhinitis who were diagnosed with the help of history of allergy, positive signs for allergy, blood samples, and positive skin prick tests; while the control group included 43 age- and sex-matched healthy volunteers with negative skin prick tests. The demographic data, medical history, findings in the physical examinations, serum levels of total immunoglobulin E (IgE) and 25-hydroxyvitamin D, and skin prick test results of the groups were noted. A total of 129 patients fulfilling the necessary criteria were enrolled. The median serum 25-hydroxyvitamin D levels in the study group were significantly lower compared to the control group (P = .014). In the study group, median serum vitamin D levels were significantly higher in men, compared to women (P = .03). There was a significant negative correlation between IgE and vitamin D levels in the allergic rhinitis group (P = .028, r = -0.246). This study showed that patients with allergic rhinitis might be more vulnerable to have lower serum levels of vitamin D. Thus, vitamin D supplementation as an adjunctive therapy may be considered in those patients.

RESUMO

PURPOSE: To manage reattachment of rhegmatogenous retinal detachment using tissue adhesive (fibrin glue) in five patients. METHODS: Five eyes of five patients with rhegmatogenous retinal detachment were treated with 23-gauge pars plana vitrectomy and the application of fibrin glue (Tisseel Lyo) into the break under air without laser photocoagulation or cryopexy. RESULTS: The median age of patients was 64 (range, 46-82) years, and the median duration of symptoms was 15 (range, 7-60) days. Three eyes had inferior and two had superior rhegmatogenous retinal detachments. Successful retinal reattachment was achieved in all cases and maintained during the following 10 to 24 months. The median best-corrected visual acuity improved from 2 / 100 preoperatively to a Snellen visual acuity of 20 / 50 by 6 months postoperatively. No postoperative complications were detected during the follow-up period. CONCLUSIONS: Excellent adhesive effects of fibrin glue with respect to sealing retinal tears with no side effects were seen in our study. With further prospective studies, this technique could be an alternative method to conventional retinopexy.

RESUMO

Background: This study aimed to identify optical coherence tomography (OCT) biomarkers for predicting response to anti-VEGF treatment in diabetic macular edema (DME)Methods: Bilateral DME patients with asymmetric response to a loading dose of anti-VEGF (ranibizumab/aflibercept) treatment were retrospectively studied. The morphologic response criterion was central subfield thickness (CST) ≤300 µm; asymmetric response was defined as ≥10% difference in CST reduction between the eyes. The functional response criterion was an increase in logMAR acuity of ≥3 lines, with an increase below this threshold in the fellow eye considered asymmetric response. Relationships between final morphologic and functional responses to anti-VEGF therapy and baseline values of the following OCT-derived biomarkers were evaluated: DME subtype, CST, vitreoretinal interface anomalies, disorganization of the inner retinal layers (DRIL), external limiting membrane (ELM) disruption, ellipsoid zone (EZ) disruption, and subretinal fluid (SRF).Results: After a loading dose of anti-VEGF, 31 eyes that met both morphologic and functional response criteria were classified as responders (RR) and 27 eyes that did not respond morphologically or functionally based on the defined criteria were classified as resistant (RT). Eyes that showed only functional (n = 5) or morphological response (n = 1) were excluded due to their small number. The presence of SRF or simple epiretinal membrane (ERM) was not associated with any difference in treatment responses (p > .05), while tractional ERM, extensive DRIL (≥500 µm), and ELM and EZ disruptions in the fovea-centered 1000-µm zone were important OCT biomarkers in predicting resistance (p < .001). A multilayer perceptron model ranked predictive power as 100% for ELM disruption, 51.7% for tractional ERM, 25.4% for DRIL, and 24.5% for EZ disruption.Conclusion: Extensive ELM disruption was the strongest OCT biomarker to predict anti-VEGF resistance, followed by tractional ERM. EZ disruption and DRIL had relatively lower predictive value.

RESUMO

Few authors have studied differences in craniofacial morphology of adults with chronic otitis media (COM). We sought to compare the craniofacial measurements of patients with COM with otherwise healthy adults. The study group included 120 adult patients. The control group had 30 men and 30 women without evidence of otitis media; a COM group consisted of 30 men and 30 women with COM. Craniofacial measurements were assessed retrospectively using a two-dimensional reformatted CT method. Multiple linear (bony and cartilaginous auditory tube length, size of the mastoid, height of the jugular bulbus, intercochlear distance, bitemporal distance, distance between pharyngeal orifices, and some cephalometric cranial base distances), angular (auditory tube angle, cranial base angle), and area (axial and sagittal nasopharynx size) measurements were performed. In addition, petrosquamosal (Körner's) septum prevalence and size were evaluated. No statistically significant differences were found regarding craniofacial variables except mastoid size (mastoid depth and length). None of the craniofacial parameters showed significant differences between adults with COM and adults without evidence of otitis media, when age, sex, and race were considered. No statistically significant differences were found when mastoid size was compared with unilateral and bilateral COM. No statistically significant difference was found between mastoid size of the intact side and involved side of the unilateral patients with COM. Patients with unilateral and bilateral COM may be in the same group, genetically or environmentally, as far as mastoid size is concerned. Small mastoid size correlates with COM, but development of clinical disease should be under the control of different factors.

RESUMO

OBJECTIVES: The aim of this study was to evaluate central macular thickness (CMT) and choroidal thickness (CT) in the eyes of patients with cardiovascular risk factors (CVRF). METHODS: A cross-sectional, prospective observational study of 92 patients with CVRF and 21 healthy individuals was conducted. Patients were divided into four groups according to the SCORE system. CMT was evaluated via spectral-domain-optical coherence tomography (SD-OCT). CT at five defined points (subfoveal) [SF] and nasal 500 µm [N0.5] and 1500 µm [N1.5] and 500 µm [T0.5] and temporal 1500 µm [T1.5] from the center of the fovea were measured via enhanced depth imaging (EDI)-OCT. RESULTS: Mean SFCT at right eyes (RE) and left eyes (LE) were 311.21 ± 77.7 µm and 303.5 ± 49.6 µm, respectively, in patients with mild CVRF (Group 1); 266.5 ± 63.2 µm and 267.0 ± 62.6 µm, respectively, in patients with moderate CVRF (Group 2); 264.7 ± 57.5 µm and 272.3 ± 64.6 µm, respectively, in patients with high CVRF (Group 3); 272.3 ± 64.6 µm and 271.2 ± 63.4 µm, respectively, in patients with very high-risk CVRF (with coronary arterial disease (CAD) (Group 4); and 352.0 ± 74.4 µm and 363.1 ± 89.0 µm, respectively, in the control group. CT (at both eyes) was significantly lower at the subfoveal location in all study groups (P < 0.05), but at nasal and at temporal quadrants of group 3 and group 4 (P < 0.05). No significant difference in CMT was detected between the study and control groups. CONCLUSIONS: This study demonstrated that CVRF might result in a remarkably thinner CT. Furthermore, subretinal drusenoid deposits were detected at a higher rate in the patients with CVRF than controls, and that rate increased in accordance with the severity of CAD. In the future, changes in CT may be used as a promising novel biomarker as part of the SCORE system prior to the development of CAD.
