SummaryThe precisionFDA Truth Challenge V2 aimed to assess the state-of-the-art of variant calling in difficult-to-map regions and the Major Histocompatibility Complex (MHC). Starting with FASTQ files, 20 challenge participants applied their variant calling pipelines and submitted 64 variant callsets for one or more sequencing technologies (~35X Illumina, ~35X PacBio HiFi, and ~50X Oxford Nanopore Technologies). Submissions were evaluated following best practices for benchmarking small variants with the new GIAB benchmark sets and genome stratifications. Challenge submissions included a number of innovative methods for all three technologies, with graph-based and machine-learning methods scoring best for short-read and long-read datasets, respectively. New methods out-performed the 2016 Truth Challenge winners, and new machine-learning approaches combining multiple sequencing technologies performed particularly well. Recent developments in sequencing and variant calling have enabled benchmarking variants in challenging genomic regions, paving the way for the identification of previously unknown clinically relevant variants.

Purpose. To compare perioperative visual field (VF), balance functions (BF), and changes in the other ocular parameters in patients undergoing upper eyelid dermatochalasis (DC) surgery. Methods. One hundred and fifty-eight eyes of 79 patients who underwent DC surgery were included in the study. The VF, BF, intraocular pressure (IOP), pachymetry (PM), macular, and optic nerve measurements were recorded. Measurements were repeated at postoperative month 1. The preoperative and postoperative ocular measurements and the balance data were compared. Results. Nineteen of 79 (24.05%) patients were male and 60 of 79 (75.95%) were female, while the mean age of the patients was 58.65 ± 7.38 years. There were statistically significant differences in terms of VF and macular thickness between the preoperative and postoperative values. The improvements in mean defect, standard loss variance, and mean sensitivity values of global VF parameters in both eyes were statistically significant after surgery. Central macular thickness, mean macular thickness, and macular volume decreased significantly in all eyes after surgery (p<0.05). Conclusions. Although a marked improvement was observed in VF and peripheral vision after surgery, no significant change was found in BF parameters including primarily falling risk. The significant change in the macular parameters was only remarkable, and we think that the decrease was due to subtle vasospasm. There is a need for further comprehensive studies including especially patients older than 65 with a view to understanding the effect of DC surgery on BF.

Ayan, Ayse/0000-0001-9488-2611; Kucuk, Mehmet Fatih/0000-0002-2548-7869; EROL, Muhammet Kazim/0000-0002-1720-8065 WOS: 000492324700003 PubMed: 31650451 Aims Determining whether nailfold capillary involvement is present in patients with Age-related macular degeneration (AMD) and whether there are different nailfold capillaroscopy findings between wet and dry types. Methods From January 2016 to December 2017, with an initial diagnosis of AMD, 53 consecutive adult patients (AMD group) and 91 age- and sex-matched healthy individuals were studied prospectively. There was no history of any other ocular disease and other disease affecting nailfold capillaries. All subjects underwent a complete ophthalmic examination. The classified and advanced stages of wet and dry types were not included. All nailfold capillaroscopy examinations were performed by the same rheumatologist. Results It was found that the frequency of major capillaroscopic findings such as capillary ectasia, micro-hemorrhage, tortuosity, neo-formation, bizarre capillary, and bushy capillaries increased in the AMD group according to the normal group, but no significant relationship was found for capillary aneurysm. In dry or wet type of AMD in terms of ectasia, micro-hemorrhage, tortuosity, neo-formation, bizarre structure, bushy structure, or aneurism of nailfold capillaries, no significant correlation was found. Conclusions Nailfold capillaroscopy can detect microvascular changes in the nailfold capillary, in early and late stages of AMD. There were morphological changes in the nailfold capillaries of AMD patients, suggesting that there are systemic superficial microvascular changes that may be due to the systemic nature of the disease.

To evaluate the effect of colour discrimination ability on the stereoscopic acuity by comparing individuals having congenital colour vision deficiency (CCVD) with healthy individuals.A comparative study.The study included 53 binocular males, of whom 26 (mean age, 36.04 ± 9.30 years) were in the healthy group and 27 (mean age, 33.04 ± 9.81 years) were in the CCVD group.The following tests were used: the Ishihara pseudo-isochromatic plate test for detecting CCVD, the Farnsworth Munsell 100 (FM100) hue test for colour discrimination ability, the TNO and Titmus stereo tests for stereoscopic acuity.In the CCVD group, 20 males were deutan and 7 males were protan. According to the FM100 hue test, total error score (TES), blue/yellow (b/y) local error score (LES), and red/green LES were significantly lower in the healthy group (30.23 ± 18.78, 15.15 ± 10.38, and 13.88 ± 11.93, respectively) than in the CCVD group (133.59 ± 67.45, 41.15 ± 22.03, and 89.15 ± 52.16, respectively) (p0.01 for each). The stereo test scores revealed significantly higher stereoscopic acuity in the healthy group (43.85 ± 33.92 arcsec for the TNO test and 40.00 ± 0.00 arcsec for the Titmus test) than in the CCVD group (93.33 ± 90.51 arcsec for TNO stereo test and 52.96 ± 24.62 arcsec for the Titmus test) (p0.05 for each). The TNO test score was significantly and positively correlated with the TES (r = 0.390, p = 0.049) and b/y LES (r = 0.490, p = 0.011) in the healthy group.Colour discrimination ability affected stereoscopic acuity. Moreover, stereoscopic acuity increased with increasing colour discrimination ability, which could be originated from the b/y colour region.

PurposeJuvenile myoclonic epilepsy (JME) is commonly associated with photoparoxysmal response (PPR) with a reported prevalence of 25–42%. In this study, we aim to explore the relationship between the PPR and Optical Coherence Tomography (OCT) parameters in order to determine whether optic nerve fiber layer or other structural differences have a pathophysiological role of photosensitivity in patients with JME.MethodsWe studied 53 consecutive patients with Juvenile myoclonic epilepsy (JME) at our outpatient department. The interictal electroencephalogram (EEG) findings for each patient were analyzed for the presence of photoparoxysmal features. The peripapillary Retina Nerve Fiber Layer (RNFL) thickness, ganglion cell thickness, macular thickness and choroid thickness levels were analyzed using OCT.ResultsWe classified the patients into two groups as those with PPR (Group 1) and those without PPR (Group 2). There were statistically significant differences in the average RNFL thickness values of the left eye between the two groups (p

A 33-year-old male presented to our clinic with low vision in both eyes that started during the previous week. Visual acuity was 20/63 in the right eye and 20/50 in the left eye. Fundus examination revealed signs of hypertensive retinopathy; thus, a multidisciplinary approach was adopted for the diagnosis and treatment of this patient. We consulted the nephrology and cardiology departments on this case. Upon diagnosing malignant hypertension and renal failure, the patient was put on hemodialysis. His visual acuity was 20/20 at 6 months, whereas foveal assessment on optical coherence tomography angiography revealed neither marked superficial and deep capillary density loss and foveal avascular zone enlargement nor a decrease in disc flow and radial peripapillary capillary density. Early diagnosis and treatment of malignant hypertension are critical in preventing progression of end-organ damage including the eyes. Optical coherence tomography angiography may be useful in cases when fundus fluorescein angiography is relatively contraindicated (e.g., renal failure).

BACKGROUND Pulmonary thromboembolism (PE) is a major disease in respiratory emergencies. Thoracic CT angiography (CTA) is an important method of visualizing PE. Because of the high radiation and contrast exposure, the method should be performed selectively in patients in whom PE is suspected. OBJECTIVES The aim of the study was to identify the role of clinical scoring systems utilizing CTA results to diagnose PE. MATERIAL AND METHODS The study investigated 196 patients referred to the hospital emergency service in whom PE was suspected and CTA performed. They were evaluated by empirical, Wells, Geneva and Miniati assessments and classified as low, intermediate and high clinical probability. They were also classified according to serum D-dimer levels. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated and evaluated according to CTA findings. RESULTS Empirical scoring was found to have the highest sensitivity, while the Wells system had the highest specificity. When low D-dimer levels and "low probabilty" were evaluated together for each scoring system, the sensitivity was found to be 100% for all methods. Wells scoring with a cut-off score of 4 had the highest specificity (56.1%). CONCLUSIONS Clinical scoring systems may be guides for patients in whom PE is suspected in the emergency department. The empirical and Wells scoring systems are effective methods for patient selection. Adding evaluation of D-dimer serum levels to the clinical scores could identify patients in whom CTA should be performed. Since CTA can only be used conservatively, the use of clinical scoring systems in conjunction with D-dimer levels can be a useful guide for patient selection.

Objective To determine the frequency of sicca complex, Sjogren's Syndrome (SS) and Fibromyalgia (FM) in patients with Irritable Bowel Syndrome (IBS). Methods Seventy seven IBS patients who fulfilled the Rome-III criteria were included in the study. All patients were assessed for FM according to the American College of Rheumatology (ACR) 2010 criteria. After examination for objective evidence of sicca complex by Schirmer test, TBUT and Ocular Staining Score (OSS), serological tests were performed. And the diagnosis of SS was made according to the American College of Rheumatology (ACR) classification criteria for SS - 2012. Results Thirteen (16.9%) of IBS patients had FM. Dry eye was detected in 20(26.0%), 7(9.1%) and 29(37.7%) patients by OSS, Schirmer test and TBUT, respectively. Of 77 patients with IBS, the diagnosis of SS was established in two patients (2.6%). Conclusion The frequency of Sjogren's Syndrome among patients with IBS is relatively higher than the general population. All IBS patients should be questioned for dryness of the mouth and eyes, and if necessary, should be evaluated for SS.

Objectives: This study aims to evaluate the alterations of retinal layers in rheumatic patients treated with hydroxychloroquine but without the signs or symptoms of retinopathy by using spectral domain ocular coherence tomography (SD-OCT). Patients and methods: The retinal layers of a total of 402 eyes including 114 patients treated with hydroxychloroquine (for rheumatoid arthritis (n=40), Sjogren’s syndrome (n=47) and connective tissue diseases (n=27) and age-matched 87 healthy controls were evaluated with SD-OCT. The macular cube protocol, optic disc cube protocol and horizontal and vertical HD 5-line raster scan protocol were applied. The measured parameters were compared between hydroxychloroquine users and healthy control group. The results of these parameters were also compared with other disease groups using hydroxychloroquine. The correlation of these parameters with the duration of drug consumption and dose was assessed. Results: All layers of outer fovea, superior and inferior quadrants of retinal nerve fiber layers of hydroxychloroquine users were thinner than nonusers. Connective tissue disease group had longer duration and higher cumulative dose of hydroxychloroquine than other diagnostic groups. This group had thinner mean retinal nerve fiber layers values than the other groups as well. There were significant and negative correlations between cumulative dose of drug and parafoveal region thickness of outer fovea and inferior quadrant of retinal nerve fiber layers. Thickness of parafoveal and perifoveal layers was negatively correlated with the dose of drug per kg of body weight. Conclusion: Our study results show that SD-OCT may be the golden standard technique for the follow-up of antimalarial-induced retinotoxicity in

Choroidal osteoma is an extremely rare osseous tumor of the choroid where choroidal neovascularization (CNV) is the major cause of visual loss. We report the case of a 28-year-old female with CNV secondary to choroidal osteoma, who developed RPE tear after intravitreal ranibizumab treatment.

To report a retrospective series of choroidal neovascularization (CNV) patients treated with intravitreal ranibizumab with good baseline vision from causes other than age-related macular degeneration (AMD).We retrospectively reviewed 12 eyes of 12 patients with CNV secondary to non-AMD who received intravitreal ranibizumab injections. Patients with baseline best-corrected visual acuity (BCVA) above 20/63 were included in the study. All patients were followed up at least for 12 months. BCVA measurement, fundus examination, and OCT examination of the patients were performed at each visit. Optical coherence tomography (OCT), fundus photo, fundus autofluorescence, and fundus fluorescein angiography examination of the eyes were obtained. Primary outcome measures were the changing in BCVA and central foveal thickness (CFT). Any ocular or systemic side-effects were recorded.The ages of patients ranged from 17 to 60. Twelve patients were diagnosed with non-AMD associated CNV: myopia (n = 3), central serous chorioretinopathy (n = 3), idiopathic (n = 2), multifocal choroiditis (n = 2), punctate inner choroidopathy (n = 1), and photo toxicity (n = 1). The improvement in visual acuity was statistically significant (p = 0.001). In the 12-month visit, all eyes had improvement in visual acuity except two eyes. The reduction of the mean CFT was statistically significant (p = 0.001). The CFT of all patients decreased in the 12-month visit. There was no significant difference in comparison of the mean intraocular pressure (p = 0.790). The group received a total of 52 intravitreal injections. The mean number of intravitreal injections was 4.3 (ranged from 3-8).Ranibizumab seems to be an effective and safe treatment option for CNVs secondary to non-AMD causes in patients with relatively good baseline BCVAs.

Aim. To asses both choroidal thickness differences among Alzheimer’s type dementia (ATD) patients, mild cognitive impairment (MCI) patients, and healthy control (C) subjects and choroidal thickness relationships with cognitive performance.Methods. A total of 246 eyes of 123 people (41 ATD, 38 MCI, and 44 healthy C subjects) were included in this study. Complete ophthalmological and neurological examination was performed in all subjects. Choroidal thicknesses (CT) were measured at seven locations: the fovea, 500-1500-3000 μm temporal and 500-1500-3000 μm nasal to the fovea by enhanced depth imaging optical coherence tomography (EDI-OCT). Detailed neurological examination including mini mental state examination (MMSE) test which evaluates the cognitive function was applied to all participants.Results. The ages and genders of all participants were similar in all groups. Compared with healthy C subjects, the CT measurements at all regions were significantly thinner both in patients with ATD and in patients with MCI than in healthy C subjects (p<0.05). The MMSE scores were significantly different among ATD patients, MCI patients, and healthy C subjects. They were19.3±1.8,24.8±0.9, and27.6±1.2in ATD, MCI, and healthy controls, respectively (p<0.001). There were also significant correlation between MMSE score and choroidal thickness at each location (p<0.05).Conclusions. CT was reduced in ATD patients and MCI patients. Since vascular structures were affected in ATD patients and MCI patients, they had thin CT. Besides CT was correlated with degree of cognitive impairment. Therefore CT may be a new biomarker in diagnosis and follow-up of MCI and ATD patients.

Purpose: To assess cognitive performance differences among primary open-angle glaucoma (POAG) patients, normal-tension glaucoma (NTG) patients, and healthy control (C) subjects. Methods: A total of 60 participants (20 POAG, 20 NTG, and 20 C subjects) were included in this study. A detailed ophthalmologic examination was performed on all participants. A spectral domain-optical coherence tomography (SD-OCT) system was used to measure the ganglion cell-inner plexiform layer (GC-IPL) and retinal nerve fiber layer (RNFL) thicknesses. To assess the cognitive performance of all participants, detailed neurological examinations, including the mini-mental state examination (MMSE), were performed by the same neurologist. Results: There were no significant differences among the groups in terms of age (p =0.348) or gender (p =0.935). The mean RNFL thicknesses were significantly different among the groups (85.2 ± 14.7, 76.8 ± 10.3, and 91.4 ± 7.7 µm in the POAG, NTG, and C subjects, respectively; p

Purpose: The author report the result of three consecutive monthly intravitreal ranibizumab injection for choroidal neovascularization (CNV) after bevacizumab injection for chronic central serous rethinopathy (CSR). Methods: A 48 year old man with chronic CSR was treated with intravitreal single dose 2.5 mg bevacizumab. One year after CNV was occurred, and three consecutive monthly intravitreal ranibizumab injections were performed. Results: Four weeks later the first ranibizumab dose, best corrected visual acuity was improved 20/80 to 20/20 and remained stable within one year. Conclusion: Repeat intravitreal ranibizumab injection in CNV after bevacizumab injection for chronic CSR appeared to be an effective treatment option.

PubMed: 21158581 Purpose: To present 3 cases with nasolacrimal canal agenesis who underwent repetitive unsuccessful probing for treatment of congenital epiphora. Materials and methods: Three patients who had undergone topical antibiotic therapy, lacrimal sac massage and repetitive probing in Ondokuz Mayis University, Medical School, Ophthalmology Department between June 2006 and March 2007 were included in the study. Thin-section computerized tomography (CT) scan was performed in all cases since nasolacrimal duct could not be detected during repetitive probing. Results: Among the patients 2 were males and 1 was a female. They were within the age range 57. Since it was not possible to cannulate the nasolacrimal canal during probing, CT scans were performed and nasolacrimal duct agenesis was detected in 3 patients. One of the patients had additional upper punctum agenesis, who also had no right frontal sinus and left sphenoid sinus. All tomographic images revealed a rudimentary upper nasolacrimal canal ending blindly and a lower canal leading into the maxillary sinus, which was very typical for the duct agenesis. In all patients, lacrimal fossas were shallow and irregular. Conclusion: Nasolacrimal duct agenesis should be considered in patients with congenital nasolacrimal duct obstruction and unsuccessful repetitive probing, especially if it is difficult to cannulate nasolacrimal canal during probing. Although assessing whether dacryocystorhinostomy is in favor of the patient, the lacrimal sac and fossa should be examined with imaging in details. © 2010 Informa Healthcare USA, Inc.

Background/aim Many autoimmune diseases occur concomitantly with celiac disease (CD). We aimed to determine the frequency of Sjogren's syndrome (SS) in CD patients based on SS-specific serology verified by minor labial salivary biopsy. Materials and methods Eight-two patients with CD were included in the study. After examination for objective evidence of sicca complex, all patients were tested for serological presence of rheumatoid factor (RF) and antinuclear antibodies (ANAs) and for ANA profile. Minor labial salivary biopsy was performed for patients with positive serology and/or clinical signs of SS. Results Of the patients included, 24 (29.3%) had dry eye symptoms while 20 (24.4%) had dry mouth symptoms. Dry eye was detected by Schirmer test in 10 patients (12.2%) and by ocular staining score in only 2 patients (2.4%). All samples were negative for RF while 12 (14.6%) samples were positive for ANAs. Of 82 patients with CD, the diagnosis of SS was established in only one patient (1.2%), while one patient (1.2%) was diagnosed with morphea and 4 patients (4.9%) were classified as having undifferentiated connective tissue disease. Conclusion The prevalence of SS in CD is low, so there is no need for serologic screening of all patients with CD for SS.

We would like to thank Ilhan et al. [1] for their comments regarding our article. In our study, we found out that choroidal thickness (CT) decreased in the eyes of patients with both Alzheimer's type dementia (ATD) and mild cognitive impairment (MCI) compared to the healthy control group. Therefore, we suggested that CT value could be used as a new biomarker in early diagnosis of ATD and MCI patients and follow-up of their progression [2].

To evaluate choroidal thickness in premature infants and its relationship with stage of retinopathy of prematurity (ROP) using spectral domain optical coherence tomography (SD-OCT).Spectral domain optical coherence tomography imaging for measuring subfoveal choroidal thickness was performed for 80 premature infants. Subfoveal choroidal thickness was defined as the distance from the hyperreflective line of the outermost retinal pigment epithelium (RPE) to the innermost hyperreflective line of the choroidoscleral junction. Each measurement was performed at the central fovea (CF) and 0.75 mm to 1.5 mm nasal (N1 and N2) and temporal (T1 and T2) to the fovea. Subfoveal choroidal thickness and grading of cystoid macular edema (CME) were analyzed statistically.Choroidal thickness of CF was found to be significantly greater than nasal (N1 and N2) and temporal (T1 and T2) choroidal thickness (P0.05). There was no significant relationship between stage of ROP and nasal (N1 and N2) choroidal thickness (P = 0.057, P = 0.282, respectively). However, CF and temporal (T1 and T2) choroidal thickness was found to be significantly lower at a higher stage of ROP (P = 0.005, P = 0.01 and P = 0.001). No significant relationship was found between subfoveal choroidal thickness and the grades of cystoid macular edema (P0.05). The choroidal thickness of CF was found to be correlated with birth weight (r = 0.267, P = 0.017) but not birth week (r = 0.140, P = 0.217). Maximum stage of ROP was found to be negatively correlated with choroidal thickness, at N1, T1, and T2 (r-0.250, P0.02).The subfoveal choroid in premature infants can be effectively evaluated using a portable SD-OCT device. Choroidal thickness gets thinner with the severity of ROP and the decrease is more prominent at the central and temporal location. Cystoid macular edema is not correlated with choroidal thickness in premature infants.

This study entailed a cross-examination of oxidant/antioxidant balance, high-density lipoprotein (HDL)-linked paraoxonase 1 (PON1) phenotypes, and levels of serum routine lipids among patients with normal tension glaucoma (NTG) or pseudoexfoliative glaucoma (PEXG) compared with healthy control groups. We aimed to investigate the links between oxidative stress (OS), HDL-related antioxidant enzyme activities and dyslipidemia in distinct subtypes of glaucoma. The study included 32 patients with NTG, 31 patients with PEXG, and 40 control subjects. Levels of PON1 and arylesterase enzymatic activity, total oxidant status (TOS), and total antioxidant status were measured by spectrophotometry and OS indexes (OSI) were calculated. The phenotype distribution of PON1 was determined using the dual substrate method. Blood serum levels of HDL, low-density lipoprotein, total cholesterol (TC), and triglyceride (TG) were measured. The TOS and OSI values in the NTG group were significantly higher compared with the other groups (both p < 0.01). The phenotype distribution found in the glaucoma and control groups were NTG: QQ, 59.4%; QR, 37.5%; RR, 3.1%; PEXG: QQ, 45.1%; QR, 48.4%; RR, 6.5%; and in the control group: QQ, 42.5%; QR, 50.0%; RR, 7.5%. Serum TC levels were significantly higher than the control in both NTG and PEXG groups, whereas TG was significantly higher in NTG only (p < 0.01 and p < 0.02, respectively). Hyperlipidemia, OS and variations in phenotype distribution of PON1 may play a role in the pathogenesis of different types of glaucoma.

The authors present enhanced depth imaging optical coherence tomography (EDI OCT) and fundus autofluorescence (FAF) characteristics of a patient with bilateral choroidal osteoma and try to make a correlation between two imaging techniques. Two eyes of a patient with choroidal osteoma underwent complete ophthalmic examination. Enhanced depth imaging optical coherence tomography revealed a cage-like pattern, which corresponded to the calcified region of the tumor. Fundus autofluorescence imaging of the same area showed slight hyperautofluorescence. Three different reflectivity patterns in the decalcified area were defined. In the areas of subretinal fluid, outer segment elongations similar to central serous chorioretinopathy were observed. Hyperautofluorescent spots were evident in fundus autofluorescence in the same area. Calcified and decalcified portions of choroidal osteoma as well as the atrophy of choriocapillaris demonstrated different patterns with enhanced depth imaging and fundus autofluorescence imaging. Both techniques were found to be beneficial in the diagnosis and follow-up of choroidal osteoma.

Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare malignant epithelial tumor most commonly observed in the scalp and skin of the chest and originating from the palpebral portion of the lacrimal gland in the orbit. Here we describe the diagnosis and treatment of a rare case of PCACC in an eye of a 52-year-old male. The patient presented with a mass lesion of the right lower eyelid. During incisional biopsy, lack of encapsulation and a secretion pattern different to that of chalazion was observed, which differentiated the lesion from chalazion. Pathological analysis revealed the diagnosis of PCACC. This case highlights the importance of careful inspection for macroscopic differentiation of PCACC from chalazion after initial surgery and pathological evaluation of all surgically removed mass lesions for accurate diagnosis and treatment.

Sarı, Esin Söğütlü (Balikesir Author), Bone marrow-derived multiple myeloma is a type of plasma cell tumor that may be associated with ocular complications. A 52-year-old male patient was admitted to our eye clinic with the complaint of sudden visual loss and a visual acuity of 20/50 in the right eye and 20/800 in the left eye. Fundus examination revealed common flame-shaped hemorrhages, venous dilatation and tortuosity, Roth spots, serous macular detachment, and yellow macular deposits in both eyes. Evaluation with fundus fluorescein angiography, fundus autofluorescence, and spectral-domain optical coherence tomography resulted in suspicion of hyperviscosity retinopathy and referral to the hematology clinic. After hematology consultation confirmed a diagnosis of multiple myeloma, chemotherapy and plasmapheresis were initiated. Four months after presentation, best-corrected visual acuity was 20/20 in both eyes and improvement in hyperviscosity retinopathy, serous macular detachment, and yellow macular deposits was observed.

Purpose. To evaluate the repeatability of measurement of central corneal thickness (CCT) by spectral domain optical coherence (SD-OCT) in premature infants and compare it to CCT measurement by ultrasonic pachymetry (USP).Methods. Three CCT measurements of the left eyes of 50 premature infants were obtained by SD-OCT using the iVue system. 10 CCT measurements of each 28 left eyes of 28 infants were obtained by USP using the Pacscan 300P system. Bland-Altman plots were developed and the limit of agreement (LoA) was determined to compare the mean of the SD-OCT and USP measurements.Results. No statistically significant difference was found among the 3 CCT measurements by SD-OCT. Both USP and SD-OCT have been performed for only left eyes of 28 of the 50 babies. Those results have been compared with each other. A statistically significant difference was found between the mean CCT measurements by SD-OCT and USP (p<0.05). The LoA between the SD-OCT and USP measurements ranged from 11.4 to −64.1.Conclusions. CCT can be measured using the iVue SD-OCT system with a high level of repeatability. Although measurement of CCT by SD-OCT and USP is highly correlated, the 2 systems cannot be used interchangeably in premature infants.

Sarı, Esin Söğütlü (Balikesir Author), Purpose: To compare the efficacy of intravitreal ranibizumab and bevacizumab treatment for type 1 retinopathy of prematurity (ROP). Methods: 36 eyes of 20 patients with type 1 ROP who received anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections between August 2011 and February 2013 were retrospectively evaluated. Fifteen eyes of 8 patients received 0.25 mg ranibizumab (group 1), and 21 eyes of 12 patients received 0.625 mg bevacizumab (group 2). Eyes were examined by indirect ophthalmoscopy on the first day, third day, first week, and first month and as required after injections. Laser photocoagulation was performed in cases with progression of ROP. Results: The mean gestation time was 26.2 +/- 2.7 weeks in group 1 patients and 27.1 +/- 2.5 weeks in group 2 patients. No statistical difference in the time of gestation was observed between the two groups. The mean follow-up period was 20 +/- 4.5 months. Laser photocoagulation was performed in 6 of 15 eyes from group 1 and 2 of 21 eyes from group 2. No eyes developed retinal detachment during the follow-up period. Conclusion: Ranibizumab and bevacizumab showed an efficacy in the treatment of type 1 ROP. The incidence of disease relapse was higher in eyes which received ranibizumab. Further randomized, controlled clinical trials are required to compare the efficacy of ranibizumab and bevacizumab.

Sarı, Esin Sögütlü (Balikesir Author), Purpose: To report the anatomical and visual results in patients diagnosed as having retinal pigment epithelium (RPE) tears after receiving ranibizumab injections. Methods: Eyes diagnosed as having RPE tears with a minimum 6-month follow-up were retrospectively evaluated. Each eye was treated with at least three doses of ranibizumab at monthly intervals. Best-corrected visual acuity (BCVA), anterior segment findings, intraocular pressure, and fundus examination results were evaluated during control visits. Color fundus photography, fundus fluorescein angiographies, fundus autofluorescence, and spectral domain optical coherence tomography (SD-OCT) images were obtained. The height of pigment epithelial detachment (PED) was measured by SD-OCT. Results: Twelve eyes with RPE tears were studied. Nine eyes (75%) developed RPE tears during ranibizumab injections for choroidal neovascularization (eight eyes with vascularized PED and one eye with choroidal osteoma), and tears occurred in three eyes before any injections. The median number of ranibizumab injections after diagnosis of RPE tears was 3 (min 2, max 5). In the most recent follow-up visit, there was no statistically significant correlation between the grade of RPE and logMAR of BCVA (p>0.05, r=0.112). Eight of twelve eyes had PED, and seven of these had irregular PED contours before injection therapy. The mean PED height was 447 +/- 122 mu m. Conclusions: In this series, RPE tears developed mostly after intravitreal anti-VEGF injections for vascularized PED. Increased vertical height and irregular contours of the PEDs can be risk factors for the formation of RPE tears. The continuation of anti-VEGF therapy after tear formation is beneficial for vision improvement in eyes with RPE tears.

Purpose: To investigate the clinical and macular spectral-domain optical coherence tomography (SD-OCT) findings after intravitreal ranibizumab treatment for type 1 retinopathy of prematurity (ROP). Methods: Eighteen eyes of 10 premature infants with type 1 ROP were retrospectively studied. All eyes were treated with intravitreal ranibizumab as monotherapy. Macular SD-OCT was performed before and after intravitreal ranibizumab therapy using a portable SD-OCT machine; the follow-up images were taken 1 day, 1 week, 1 month, and 2 months after therapy. Results: Among the 10 infants, there were six males and four females. Mean central foveal thickness before and 2 months after intravitreal ranibizumab was 292.5 ± 61.4 and 171.6 ± 21.7 µm, respectively. Differences were statistically significant ( P = .01). Sixteen eyes of eight patients had macular edema before treatment. Two eyes of two patients developed a crack in the outer hyperreflective line on SD-OCT corresponding with retinal pigment epithelium with serous retinal detachment 1 day after treatment. Macular edema regressed in all patients 2 months after intravitreal ranibizumab therapy. Mean follow-up time was 11.4 ± 1.5 months. No recurrence was seen except in both eyes of one patient treated with intravitreal ranibizumab monotherapy. Conclusions: Intravitreal ranibizumab injection is effective for the treatment of type 1 ROP as a monotherapy agent; however, macular changes not seen with indirect ophthalmoscope may develop.

Aim: Evaluation of external dacryocystorhinostomy surgery in patients with nasolacrimal canal obstruction and the effects of the incision type on the functional and esthetic outcomes. Material and Methods: Outcomes of 49 patients who underwent external dacryocystorhinostomy and bicanalicular silicon tube intubation(when necessary) for nasolacrimal canal obstruction between 2004 and 2008 were evaluated retrospectively. The effects of oblique incision, used between 2004-2005, and the vertical incision, used between 2006-2008, on the functional and cosmetic outcomes were evaluated. The patients were asked to complete a survey on preoperative symptoms, functional outcomes of the operation, and the patient satisfaction with the scar tissue and cosmetic outcomes. The results were compared statistically. Results: Mean age of the 49 patients (35 females and 14 males) was 42.63±15.57 (19-72). Except for the 2 patients operated in other centers, first operations of 47 patients were performed in our clinic. Five patients required revision surgery due to functional failure. Jones’ tube implantation was performed in 1 of the 3 patients with persistant epiphora. No serious complications were observed postoperatively, except for mild nasal hemorrhage. Three patients, (2 of witch had persistent epiphora), were not satisfied with the surgery. Silicon intubation was performed to 21 patients during surgery. Outcomes were satisfactory in 46 patients. In each of the 2 incision groups, 7 patients had noticeable scars but they were satisfied esthetically. It was observed that the type of incision used, either oblique or vertical, had no effect on the functional outcome of surgery. On the contrary, it was determined that vertical incision yielded better cosmetic outcomes.Conclusion: External dacryocystorhinostomy is a successful surgery for patients with nasolacrimal canal obstruction. Incision type does not affect the functional outcomes of the surgery but it does affect the cosmetic outcomes.

Lazer isaretleyicinin lazerine maruz kalma sonucu makula yanigi gelisen hastanin sunumu amaclanmistir. Yirmi bes yasinda erkek hastanin sag gozu, birkac saniye lazer isaretleyicinin lazerine maruz kalmistir.

Macular burn associated with exposure of pointer laser It was aimed to present a case of macular burn associated with exposure of pointer laser in the study. Twenty five years old male patient had exposed laser pointer beam to his right eye for a few seconds. Eye examination disclosed his vision was intact except lower central disturbances like refraction and bending errors and natural anterior segment findings. Posterior segment examination showed laser-induced yellow burn on the fovea. The patient was treated with topical carbonic anhydrase inhibitor, oral and topical steroids and followed up. It was observed that vision of the patient resolved completely at the end of follow up period. J. Exp. Clin. Med., 2012; 29:S97-S98
