Investigation of anterior segment structures of the eye in Behçet's disease using in vivo confocal microscopy.

PURPOSE: We sought to investigate alterations in the corneal subbasal nerve plexus and endothelium in patients with Behçet's disease (BD). METHODS: This cross-sectional study included 64 patients with BD and 30 age- and gender-matched healthy control subjects. Those with BD were classified as having ocular or non-ocular disease. All subjects underwent a corneal endothelial and subbasal nerve density evaluation using in vivo confocal microscopy (IVCM). The differences among groups were analyzed using the Kruskal-Wallis test followed by Dunn's multiple comparison procedure. RESULTS: The mean age of study participants was 35.7 ± 10.2 years (16-58) in the ocular BD group, 39.6 ± 14.9 years (11-66) in the non-ocular BD group, and 34.1 ± 11.2 years (21-55) in the control group. No statistical significance was found in terms of age (p = 0.259) or sex (p = 0.560) between groups. The mean endothelial cell density determined with IVCM was 2124.9 [Formula: see text] 417.4 cells/mm2 (1811-3275) in the ocular group and 2546 [Formula: see text] 335 cells/mm2 (1798-3280) in the control group (p = 0.000). In the ocular group, the mean density of the subbasal nerve plexus was significantly lower (p = 0.004), and nerve tortuosity was significantly higher (p = 0.002). CONCLUSIONS: Ocular BD could be responsible for changes in the corneal layers, especially endothelial and corneal nerve structures. Nerve density and tortuosity differences could be inflammatory indicators for BD.

Assessment of systemic and ocular inflammation in juvenile idiopathic arthritis via choroidal vascularity index.

We aimed to evaluate the retina and the choroid in children with juvenile idiopathic arthritis (JIA) employing optical coherence tomography (OCT). This cross-sectional study, carried out between June 2017-December 2019, included JIA patients with (JIAU; n = 28) and without (JIAN; n = 65) uveitis and age-matched healthy controls (HC) (n = 102). Laboratory and demographic information of the children were obtained from hospital records. Activity of the disease was evaluated by the Juvenile Arthritis Disease Activity Score-71 (JADAS-71). Choroidal scans were obtained with spectral domain-OCT in enhanced-depth imaging (EDI)-OCT mode to assess choroidal thickness (ChT) at five locations (under the fovea, at 750 and 1500 µm nasal and temporal sections), luminal area (LA), stromal area (SA), total subfoveal choroidal area (TCA) and CVI (choroidal vascularity index). Central foveal thickness (CFT) and 1-mm diameter foveal thickness (FT) were calculated automatically through macular volume scan analysis. The choroid was significantly thicker in JIAU and JIAN patients than in HC at the subfoveal and at the 750N, 750T, 1500T points (p < 0.001, p = 0.009, p < 0.001, and p < 0.001, respectively). The CVI was lower in JIAU patients than in JIAN patients and HC (p = 0.02). Conversely, CFT was greater in JIAU patients as compared to the JIAN patients and HC (p = 0.02). Changes in chorioretinal OCT parameters in the absence of uveitis in JIA patients may reflect subclinical choroidal inflammation in these patients. Ophthalmologic examination, including choroidal imaging in a larger cohort, may clarify this aspect.

Retinal degeneration is associated with brain volume reduction and prognosis in radiologically isolated syndrome.

BACKGROUND: The extent of neurodegeneration in the earliest stages of central nervous system (CNS) demyelination is not known. Optical coherence tomography (OCT) is a powerful tool to study neurodegeneration in demyelinating disorders. OBJECTIVES: To study neuroaxonal loss in the retina of individuals with radiologically isolated syndrome (RIS) and investigate whether OCT measurements are associated with brain volumetrics and clinical conversion to multiple sclerosis (MS). METHODS: Subjects fulfilling the Okuda criteria for RIS (n = 15 patients, 30 eyes) and age- and sex-matched healthy controls (HC) underwent spectral-domain OCT and magnetic resonance imaging for volumetric measurement of brain structures. RESULTS: Macular ganglion cell-inner plexiform layer (mGCIPL), macular retinal nerve fiber layer (mRNFL), and temporal peripapillary RNFL (pRNFL) thickness; normalized total brain volume (nTBV); and normalized thalamic volume (nTV) were reduced in RIS compared to HC. mGCIPL, mRNFL, and pRNFL measurements were associated with nTBV, nTV, and normalized gray and white matter volumes in the RIS group. pRNFL was thinner in individuals with RIS who converted to MS in 5 years. CONCLUSIONS: Retinal neurodegeneration can be detected in the papillomacular region in the earliest stages of CNS demyelination and reflects global disease processes in the brain. OCT can be potentially useful for predicting prognosis in RIS.

Complement Factor I Gene Polymorphism in a Turkish Age-Related Macular Degeneration Population.

OBJECTIVE: Evaluation of Complement Factor I (CFI) rs10033900 and rs2285714 polymorphism frequencies in patients with age-related macular degeneration (AMD) and healthy controls in a Turkish population. METHODS: A total of 111 eyes of 111 AMD patients and 96 eyes of 96 healthy controls, only one eye of individuals, were included in the study; however, 2 patients' and 4 controls' samples were excluded as analyses could not be performed for rs10033900 polymorphism. The AMD patients and control group (>50 years) lacked corneal, lenticular, vitreal opacity. However, these patients did not have any retinal diseases apart from AMD. Venous blood samples of patients were collected. Central macular thickness, subfoveal choroidal thickness (SCT), presence of reticular drusen, epiretinal membrane, and pigment epithelial detachment were investigated using Spectral-Domain Optical Coherence Tomography, and the largest diameter of atrophic areas measured. Drusen properties were documented from fundus photographs. The lesion width was calculated by using fundus fluorescein angiography. RESULTS: There was no difference between patient and control groups and polymorphism distributions. The frequency of the CT allele was higher in patients with dry-type AMD with retinal pigment epithelial abnormality (p = 0.041). SCT was significantly thinner in TT allele carriers with rs2285714 polymorphism (p = 0.030). No significant relationship was found between the other parameters and polymorphism distributions. Con-clusion: CFI rs10033900 and rs2285714 polymorphisms in a Turkish population were not associated with AMD.

Efficacy and Safety of Sarilumab for the Treatment of Posterior Segment Noninfectious Uveitis (SARIL-NIU):: The Phase 2 SATURN Study.

PURPOSE: To assess efficacy and safety of sarilumab, a human anti-interleukin-6 receptor antibody, for treatment of posterior segment noninfectious uveitis (NIU). DESIGN: Randomized, double-masked, placebo-controlled, phase 2 study. PARTICIPANTS: Fifty-eight patients (eyes) with noninfectious intermediate, posterior, or panuveitis. METHODS: Eyes received treatment every 2 weeks for 16 weeks with subcutaneous sarilumab 200 mg or placebo. MAIN OUTCOME MEASURES: The primary end point was the proportion of patients with ≥2-step reduction in vitreous haze (VH) on the Miami scale or with a reduction of systemic corticosteroids (prednisolone or equivalent) to a dose of <10 mg/day at week 16. Primary end point was based on VH evaluation by a central reading center. Investigator evaluation of VH was a prespecified, planned secondary analysis. RESULTS: At week 16, proportion of patients taking sarilumab or placebo with ≥2-step reduction in VH or corticosteroid dose <10 mg/day was 46.1% vs. 30.0% (P = 0.2354) based on central reading center assessment of VH and 64.0% vs. 35.0% (P = 0.0372) based on investigator assessment of VH, respectively. In the subgroup of eyes with VH grade ≥2 at baseline, the mean VH reduction from baseline to week 16 was significantly greater with sarilumab vs. placebo regardless of assessment by the central reading center (-2.1 [n = 11] vs. -1.7 [n = 3], respectively; P = 0.0255) or investigator (-2.5 [n = 19] vs. -1.2 [n = 11], respectively; P = 0.0170). The mean best-corrected visual acuity gain from baseline to week 16 was greater with sarilumab vs. placebo in the overall population (8.9 vs. 3.6 letters, respectively; P = 0.0333) and in the subgroup of eyes with central subfield thickness (CST) ≥300 µm at baseline (12.2 [n = 13] vs. 2.1 [n = 7] letters, respectively; P = 0.0517). Corresponding changes in CST were -46.8 vs. +2.6 µm (P = 0.0683) in the overall population and -112.5 [n = 13] vs. -1.8 [n = 6] µm (P = 0.1317) in the subgroup of eyes with CST ≥300 µm at baseline, respectively. The most common ocular adverse events were worsening of uveitis (0 [placebo] and 3 [sarilumab] patients) and retinal infiltrates (1 [placebo] and 2 [sarilumab] patients). CONCLUSIONS: Subcutaneous sarilumab may provide clinical benefits in the management of NIU of the posterior segment, especially in eyes with uveitic macular edema.

The Potential Role of Dietary Antioxidant Capacity in Preventing Age-Related Macular Degeneration.

Objectives: Age-related macular degeneration (AMD) is a progressive disorder among people aged ≥50 years. Some dietary factors associated with the susceptibility to AMD include dietary glycemic index and glycemic load, as well as intake of antioxidants and other nutrients, such as vitamins, minerals, and dietary fatty acids. Methods: This case-control study was conducted between July 2015 and February 2016 on 100 case subjects with AMD and 100 healthy controls without AMD. The participants were recruited from the Department of Ophthalmology of Hacettepe University Hospitals in Ankara, Turkey. Dietary intake was estimated from a 3-day food intake record and food frequency questionnaire, and anthropometric measurements were recorded. The relationship between nutritional factors and AMD was assessed using logistic regression. Results: Dietary total antioxidant intake of AMD group was found to be lower (p < 0.05) than that of healthy individuals. In a multivariate analysis, smoking, daily red meat intake, omega-6 intake, and higher glycemic index were identified as risk factors for AMD development. Meanwhile, daily fruit intake, daily fish intake, omega-3 intake, and zinc intake were associated with a protective effect. However, no difference was found in dietary total antioxidant capacity. Conclusions: In this study, a high dietary intake of carotenoids, vitamins C and E, zinc, and omega-3, as well as maintaining optimal waist circumference, were found to substantially reduce the risk of developing AMD in people aged >50 years. By contrast, in addition to smoking and old age, obesity, high red meat intake, and omega-6 intake might increase the risk of developing AMD. Therefore, a better understanding of nutritional risk factors is necessary for preventing AMD.

Abnormal retinal microvasculature found in active rheumatoid arthritis:a different perspective of microvascular health

Background/aim: We aimed to assess the association between retinal vascular caliber (RVC) scores and disease activity in rheumatoid arthritis (RA) patients. Materials and methods: Forty-seven RA patients, 32 systemic lupus erythematosus (SLE) patients, and 45 healthy people were enrolled. RA and SLE patients were subdivided into groups according to C-reactive protein (CRP) levels. RA patients were also grouped according to Disease Activity Score-28 (DAS-28). Fundus photography was performed for all patients. RVC was summarized as the central retinal artery and vein equivalents (CRAE and CRVE). Results: Mean CRVE for RA patients was 213.3 ± 17.8 µm compared with 209.2 ± 14.1 µm for SLE and 217.5 ± 26.2 µm for the control group (P = 0.17). RVC scores did not differ between the CRP-high and CRP-low groups. As the RA disease activity increased, the widening of CRVE became more prominent and statistically significant. When the DAS-28 > 5.1 (CRVE, 220.4 (211.8­246.5) µm) group and DAS-28 ≤ 3.2 (CRVE, 214.4 (172.4­242.3) µm) group were compared, statistical significance was more pronounced (P = 0.03) than when comparing the DAS-28 > 3.2 and DAS-28 ≤ 3.2 groups (P = 0.05). Conclusions: CRVE, which reflects systemic inflammation and possibly increased cardiovascular risk, was significantly increased in active RA patients. The association between retinal venular widening and disease activity, regardless of CRP, may be a sign that RA-related inflammation may have systemic vascular effects even with normal levels of CRP.

Real-World Results of Intravitreal Ranibizumab, Bevacizumab, or Triamcinolone for Diabetic Macular Edema.

OBJECTIVE: To compare the visual and anatomical outcomes of intravitreal ranibizumab (group 1), bevacizumab (group 2), and triamcinolone (group 3) for center-involving diabetic macular edema. METHODS: We retrospectively enrolled 275 eyes of 208 consecutive patients. Visual acuity (VA) in Early Treatment Diabetic Retinopathy Study (ETDRS) letters and central macular thickness (CMT) values on optical coherence tomography were extracted. Reported side effects were noted. RESULTS: At 6 months, the mean changes in VA in group 1, group 2, and group 3 were +4.9, +4.3, and +4.6 letters, respectively (p = 0.911). Improvement of CMT at 6 and 24 months was significantly better in group 3 compared to groups 1 and 2 (p = 0.012 and p = 0.001, respectively). At 24 months, the only independent variable affecting the change in VA was initial VA (p = 0.020). Cataract and glaucoma prevalences were higher in group 3 (p = 0.000 and p = 0.001, respectively). CONCLUSIONS: Three treatment methods had similar effects with regard to improvement in VA; however, intravitreal triamcinolone provided additional anatomical improvement.

Genotypic-phenotypic features and enzyme replacement therapy outcome in patients with mucopolysaccharidosis VI from Turkey.

Mucopolysaccharidosis type VI (MPS VI) is a lysosomal storage disorder (LSD) characterized by a chronic, progressive course with multiorgan involvement. In our study, clinical, biochemical, molecular findings, and response to enzyme replacement therapy (ERT) for at least 6 months were evaluated in 20 patients with MPS VI. Treatment effects on clinical findings such as liver and spleen sizes, cardiac and respiratory parameters, visual and auditory changes, joints' range of motions, endurance tests and changes in urinary glycosaminoglycan excretions, before and after ERT were analyzed. ERT caused increased physical endurance and decreased urinary dermatan sulfate/chondroitin sulfate ratios. Changes in growth parameters, cardiac, respiratory, visual, auditory findings, and joint mobility were not significant. All patients and parents reported out an increased quality of life, which were not correlated with clinical results. The most prevalent mutation was p.L321P, accounting for 58.8% of the mutant alleles and two novel mutations (p.G79E and p.E390 K) were found. ERT was a safe but expensive treatment for MPS VI, with mild benefits in severely affected patients. Early treatment with ERT is mandatory before many organs and systems are involved.

Impact of Solar Eclipses on Vision: Insights from Optical Coherence Tomography and Optical Coherence Tomography Angiography Analysis.

PURPOSE: Solar retinopathy, resulting from solar eclipse exposure, poses risks to visual health. This study explores acute and chronic phase findings using clinical examinations and optical coherence tomography (OCT) and optical coherence tomography angiography (OCT-A) with a focus on longitudinal assessment. METHODS: Seven eyes with a history of unprotected solar eclipse exposure were included. Clinical examination, fundus photography, OCT, and OCT-A imaging were performed at initial assessment, as well as at one-month and six-month follow-up intervals. Data analysis included descriptive statistics. RESULTS: The cases, exposed without protection, underwent assessments, revealing variable visual acuity, outer retinal layer, and Henle fiber layer changes during follow-up. Regression of hyperreflectivity within the outer retinal and Henle fiber layers was observed over time in all eyes, although persistent microdefects within the outer retinal layer were noted in specific cases. OCT-A imaging revealed a larger foveal avascular zone, which persisted over a six-month period in select cases. Additionally, affected eyes exhibited a decrease in superficial vascular density, with subsequent improvement noted during the six-month period. CONCLUSION: Solar retinopathy can result in visual impairment, accompanied by alterations observed in the Henle fiber layer using OCT. Additionally, OCT-A findings indicate possible vascular involvement. This study underscores the significance of adopting protective measures during solar eclipses and emphasizes the value of employing longitudinal multimodal imaging techniques to comprehend the pathophysiology of the condition.

Multimodal Imaging for Subacute Sclerosing Panencephalitis: Including Anterior Segment.

Subacute sclerosing panencephalitis (SSPE) is an irreversible and progressive neurological disorder. A 20-year-old woman with SSPE presented with a decline in visual acuity. Anterior segment was evaluated with slit lamp and in vivo confocal microscopy, revealing the presence of dendritiform keratic precipitates and +2 cells in the anterior chamber. In fundus examination, white-yellowish lesions involving the macula and periphery were observed, which gradually progressed into atrophy over time. Optical coherence tomography (OCT) imaging showed progression to atrophy of moth-eaten shaped cavities including all retinal layers due to necrotizing retinitis. OCT angiography (OCTA) further revealed reduced vessel densities and flow void areas. Notably, to the best of our knowledge, this is the first case documenting anterior segment findings in SSPE in detail. [Ophthalmic Surg Lasers Imaging Retina 2024;55:344-348.].

Evaluation of Microvascular Complications in Kidney Recipients With Posttransplant Diabetes Mellitus.

CONTEXT: The paucity of data on microvascular complications in patients with posttransplant diabetes (PTDM) is an obstacle to developing follow-up algorithms. OBJECTIVE: To evaluate diabetic microvascular complications in patients with long-standing PTDM. METHODS: In patients with ≥5-year history of PTDM and age-matched renal transplant recipients without PTDM (NDM), diabetic peripheral neuropathy was evaluated using the Michigan Neuropathy Screening Instrument, the CASE IV device, and in vivo corneal confocal microscopy (CCM). Cardiac autonomic neuropathy tests were performed using heart rate variability. Nephropathy screening was assessed using spot urine albumin/creatinine ratio and eGFR calculation. Diabetic retinopathy was evaluated by fundus examination and photography, and optical coherence tomography. RESULTS: This study included 41 patients with PTDM and 45 NDM patients. The median follow-up was 107.5 months in the PTDM group. Peripheral neuropathy was significantly higher in the PTDM group than in the NDM group (P = .02). In the PTDM patients with peripheral neuropathy, corneal nerve fiber density examined by CCM was significantly lower than in PTDM patients without neuropathy (P = .001). Parasympathetic involvement was observed in 58.5% of the PTDM group and 22% of the NDM group (P = .001). Sympathetic involvement was present in 65.9% of the PTDM group and 29.3% of the NDM group (P = .001). Retinopathy was observed in 19.5% of patients in the PTDM group and in none of the NDM patients (P < .001). Renal functions were similar between the study groups. CONCLUSION: Cardiac autonomic neuropathy and diabetic retinopathy can affect patients with PTDM at a high rate. Diabetic retinopathy is a threat to the vision of PTDM patients. Diabetic peripheral neuropathy can be detected early in PTDM patients by CCM.

The effect of CFH polymorphisms on the response to the treatment of age-related macular degeneration (AMD) with intravitreal ranibizumab.

PURPOSE: The purpose of this study is to evaluate the effect of complement factor H (CFH) Y402H CC and TT polymorphisms on treatment response to intravitreal ranibizumab injection in patients with wet age-related macular degeneration (AMD). METHODS: One hundred ninety-three patients with choroidal neovascularization (CNV) secondary to AMD who were monitored for at least 6 months of follow-up, and with at least three ranibizumab injections, were included in the study. At the final examination, an increase in visual acuity (VA) of five letters or more compared to the initial VA was regarded as a good response, and a decrease in VA of five letters or more compared to the initial VA was evaluated as a poor response. A genetic examination was performed with a PCR melting curve analysis. In the statistical evaluation, SPSS version 18 software was used. RESULTS: The mean age of the patients was 71.01 (55-86) years, the mean follow-up was 13.34 (6-36) months, and the mean number of injections was 4.02 (3-15). There were 96 patients in the good response group (Group 1) and 97 patients in the poor response group (Group 2). The initial VA in Group 1 was 41.34 (10-64) letters, the initial central macular thickness (CMT) was 213.40 (126-494) µm, and the initial lesion width was 3760 (1430-6430) µm. The initial VA in Group 2 was 52.89 (26-82) letters, the initial CMT was 257.60 (115-882) µm, and the initial lesion width was 4460 (1000-7650) µm. There was no statistically significant difference between the two groups in terms of the initial VA and CMT (p=0.094, p=0.083). However, there was a statistically significant difference between the groups in the width of the initial lesion (p=0.003). In Group 1, 15 CC, 30 TT, and 51 TC alleles were found, and in Group 2, 49 CC, two TT, and 46 TC alleles were found, and the distribution was significantly different between the two groups (p=0.012). The change in the distribution of genotypes was not associated with either the lesion size or VA (p=0.841). Fibrosis developed in 12 patients who were all poor responders. CONCLUSIONS: CFH Y402H CC accompanied a poor response, and TT accompanied a good response in this series of patients with AMD undergoing ranibizumab therapy.

Spontaneous hyphema in juvenile idiopathic arthritis uveitis.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is a rheumatic disease that may be associated with ocular involvement in childhood. Classical findings of JIA uveitis are cells and flare; hyphema, bleeding in the anterior chamber of the eye, is a rare finding. CASE: An 8-year-old girl presented with 3+ cells and a flare in the anterior chamber. Topical corticosteroids were started. A follow-up examination 2 days later revealed hyphema in the affected eye. There was no history of trauma or drug use, and the laboratory test results did not suggest any hematological disease. Systemic evaluation resulted in the diagnosis of JIA by the rheumatology department. The findings regressed with systemic and topical treatment. CONCLUSIONS: The most common cause of hyphema in childhood is trauma, but it can rarely be seen with anterior uveitis. This case highlights the importance of recognizing JIA-related uveitis in the differential diagnosis of hyphema in childhood.

Successful management of rhabdomyolysis with triheptanoin in a child with severe long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (LCHAD) deficiency.

Early-onset long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (LCHAD) deficiency is a fatty acid ß-oxidation disorder with a poor prognosis. Triheptanoin, an anaplerotic oil with odd-chain fatty acids can improve the disease course. The female patient presented here was diagnosed at the age of 4 months, and treatment was started as fat restriction, frequent feeding, and standard medium-chain triglyceride supplementation. In follow-up, she had frequent rhabdomyolysis episodes (∼8 per year). At the age of six, she had 13 episodes in 6 months, and triheptanoin was started as part of a compassionate use program. Following unrelated hospital stays due to multisystem inflammatory syndrome in children and a bloodstream infection, she had only 3 rhabdomyolysis episodes, and hospitalized days decreased from 73 to 11 during her first year with triheptanoin. Triheptanoin drastically decreased the frequency and severity of rhabdomyolysis, but progression of retinopathy was not altered.

Short-term effect of macular edema on the peripapillary retinal nerve fiber layer in patients with wet age-related macular degeneration and diabetic macular edema: A comparative study.

BACKGROUND: The combined presence of glaucoma and age-related macular degeneration (ARMD), or glaucoma and diabetes mellitus (DM), occur fairly frequently, especially in elderly patients. This study was intended to compare the effect of resolving macular edema due to DM and wet ARMD on peripapillary retinal nerve fiber layer (RNFL) thickness. METHODS: This cross-sectional study included 76 patients with macular edema secondary to DM (n = 40, 52.6%) or wet ARMD (n = 36, 47.4%). The control group was comprised of 34 age and sex-matched healthy subjects. All study participants underwent evaluation of central macular thickness (CMT) and the peripapillary RNFL using spectral domain-optical coherence tomography (SD-OCT). Data from eyes that received an anti-VEGF injection were obtained one month after the procedure and were compared with pre-injection data. RESULTS: The average initial thickness of the global peripapillary RNFL was 98.9 ± 16.7 (61-163) µm in the macular edema group and 92.0 ± 16.0 (84-115) µm in the control group (p = 0.045). The post-injection global peripapillary RNFL thickness was 97.3 ± 19.0 (61-163) µm in the macular edema group and 92.2 ± 18.0 (81-126) µm in the control group (p = 0.187). In the DM group, the changes in global RNFL thickness, as well as central and temporal quadrant thicknesses, were found to correlate significantly with the change in CMT (r = 0.356, p = 0.024; r = 0.545, p < 0.001, respectively). CONCLUSIONS: Macular edema in wet ARMD appeared not to affect RNFL thickness. Differences in the etiology of macular edema can have varied effects on peripapillary RNFL. It is recommended that peripapillary RNFL thickness be evaluated cautiously in DM patients receiving intravitreal anti-VEGF therapy.

Report of 2 pediatric cases with atypical Cogan's syndrome and a systematic review.

Cogan's syndrome (CS) is a rare inflammatory disease characterized by interstitial keratitis or uveitis, vestibular impairment, and progressive hearing loss, commonly bilateral. Although glucocorticoids are fundamental treatment options, in most cases, hearing loss gradually worsens. Herein we report 2 pediatric cases of CS who were treated with corticosteroids and methotrexate. One patient had a cochlear implant, and the hearing of the other patient improved with treatment. Also, a systematic literature review was conducted for articles including pediatric CS patients. In the literature, 34 articles describing 44 pediatric patients with CS were identified. Sudden hearing loss (95.3%) and ocular symptoms (92.5%) were the most common manifestations in these patients. Also, aortic involvement was present in 19.5% of patients in the literature. Otorhinolaryngologists, ophthalmologists, and pediatricians should collaborate to diagnose and manage CS to prevent progressive hearing loss and eye involvement.

Expert recommendations for the management of diabetic macular edema with intravitreal dexamethasone implant: A Turkish Delphi study.

PURPOSE: To provide consensus on the clinical use of intravitreal dexamethasone (DEX) implant for the treatment of diabetic macular edema (DME) in Turkey. METHODS: A panel of 22 retina experts prepared 77 statements of recommendation, and 80 retinal specialists practicing in Turkey were chosen to vote either in support or against each one. A Delphi-based method was used through which the ophthalmologists were able to view all of the results anonymously after two rounds and modify their subsequent answers. The survey was conducted via a mini website, and statements without consensus were resent to the specialists with the latest vote results a week later. RESULTS: A total of 72 ophthalmologists answered the first and second round questions. After the first stage, consensus was achieved on 55 of the statements, leaving 22 without agreement. After the second stage, consensus was reached on 11 of the remaining statements. Strong consensus was achieved on statements regarding the etiopathogenesis of DME and the first-line indications and safety of the DEX implant procedure. The panel recommended the use of DEX implant for patients with an arterial thromboembolic event in the last three months and also agreed that pro re nata DEX implant treatment not only provides better outcomes for DME patients but also reduces the treatment burden for those who could not receive an adequate number of anti-vascular endothelial growth factor (VEGF) injections. CONCLUSION: This study provides clinical consensus and recommendations about the use of DEX implant in the clinical practice of DME management in Turkey.

Recovery course of persistent posterior subretinal fluid after successful repair of rhegmatogenous retinal detachment.

PURPOSE: To investigate best corrected visual acuity (BCVA), subretinal fluid (SRF) absorption time or ellipsoid zone (EZ) restoration time and various variables in patients with persistent SRF after successful primary repair of rhegmatogenous retinal detachment (RRD). METHODS: This retrospective multicenter study allowed independent analysis of the healing pattern by two observers based on composite of serial cross-sectional macular optical coherence tomography (OCT) scans. Univariate and multivariate analyses were implemented. RESULTS: One hundred and three cases had persistent SRF after pars plana vitrectomy, scleral buckling, or pneumatic retinopexy. By univariate analysis, SRF resolution time correlated positively with the number of retinal breaks (p < 0.001) and with increased myopia (p = 0.011). Using multivariate analysis, final BCVA (log MAR) correlated positively with age, duration of RRD, initial BCVA (OR = 3.28; [95%CI = 1.44-7.47]; p = 0.015), and SRF resolution time (OR = 0.46 [95%CI 0.21-1.05]; p = 0.049). EZ restoration time was longer with increasing number of retinal tears (OR = 0.67; [95%CI 0.29-1.52]; p = 0.030), worse final BCVA, and presence of macula-off RRD (OR = 0.26; [95%CI 0.08-0.88]; p = 0.056). SRF resolution time correlated marginally with prone position. CONCLUSIONS: Residual posterior SRF is more common in eyes with multiple breaks or in myopic eyes. Final BCVA is better in younger subjects and in eyes with shorter duration of RRD. Persistent SRF is a self-limited disorder with a mean resolution of 11.2 months with good visual prognosis improving from a mean baseline logMAR of 1.08 to 0.25 at one year.
