Abstract

Salah satu masukan data dalam proses analisis kinerja kapasitas jalan raya dengan menggunakan Kapasitas Jalan Indonesia (KAJI) yaitu, data arus lalu lintas yang digolongkan atau tak tergolongkan dalam setiap kelompok kendaraan bermotor. Apabila data masukan tak tergolongkan, maka KAJI akan menggunakan nilai normal untuk komposisi kelompok kendaraan bermotor tersebut. Nilai prosentase komposisi jenis kendaraan terpengaruh oleh kondisi sosial ekonomi masyarakat, fungsi jalan, dan manajemen lalu lintas jalan bersangkutan. Dewasa ini sebagai dampak dari keberhasilan pembangunan, sejak KAJI mulai diterapkan pemakaiaannya (Thn. 1997) sampai sekarang, telah terjadi perubahan nilai prosentase komposisi jenis kendaraan bermotor. Nilai prosentase komposisi kendaraan dalam KAJI untuk jalan perkotaan terbagi lagi atas ukuran kotanya. Dalam tulisan ini yang mendjadi kasus lokasi studi dengan ukuran kota masuk dalam lingkup 1 s/d 3 juta penduduk, nilai prosentase KAJI dimana kendaraan ringan 60%, kendaraan berat 8%, dan sepeda motor 32%. Hasil penelitian yang telah dilakukan di Pusat Litbang Prasarana Transportasi menunjukan perubahan sebagai berikut, kendaraan ringan 35%, kendaraan berat 4%, dan sepeda motor 61%. Dengan adanya perubahan nilai komposisi tersebut, dalam analisis kinerja jalan menggunakan piranti KAJI, bisa memungkinkan luaran kinerja lalu lintas kurang akurat.

Abstract

Introduction: to report the characteristics, management and outcome in giant retinal tear (GRT) associated retinal detachment patients at Cicendo Eye Hospital Methods: this retrospective study was performed on medical records who had undergone retinal detachment surgery between January 2014 and March 2017. Age, sex, etiologies, size of GRT, quadrant involvement, lens status, proliferative vitreo-retinopathy (PVR), managements and outcomes were evaluated in association with giant retinal tears Result: Twenty-six patients (23 males, 3 females) age between 11-59 years with follow up from 2 months to 18 months were enrolled in this study. Twenty-five eyes have retinal detachment with macular involvement and 11 patients had high myopia. Majority of patients had 90° of GRTs. Most retinal tears were located at temporal quadrant (73%). Nineteen patients had undergone pars plana vitrectomy (PPV) and 7 patients had combined PPV with encircling buckle. Fifteen patients had used heavy liquid, 24 patients had silicon oil and 2 had gas tamponade. Intraoperative complications included lens trauma, retinal slippage and choroidal detached were found in 1 eye respectively. Fourteen eyes had recurrent retinal detachment. At the last follow up, 14 patients had anatomically attached retina. Twelve patients had total retinal detachment and marked PVR. Five fellow eyes were treated with prophylactic laser. Visual acuity improved in 11 eyes. Conclusion: Giant retinal tears were more common in patients with high myopia. Management of GRT currently with PPV and PPV combined with encircling buckle. The success rate of anatomy and visual acuity was less than other previous studies

Abstract

Introduction: Diabetic Retinopathy (DR) is a highly specific microvascular complication of both type 1 and type 2 diabetes mellitus (DM) that can cause significant visual impairment in adult populations worldwide. The risk of having and/or developing DR is influenced by many systemic features. Identification and management of particular systemic risk factors as early as possible during the course of DM might lower incidence of further progression and severity of DR. The aim of this study is to describe the correlation between systemic risk factors and DR in patients with DM in Cicendo National Eye Hospital on December 1st 2017 – January 31st 2018. Methods: An analytical cross-sectional study. The subjects were all patients diagnosed with DR based on ophthalmology examination at outpatient clinic of Vitreoretinal Division in Cicendo National Eye Hospital. The data were analyzed using chi-square (x2) with significances of p < 0.05. Result: Seventy-one eyes were included in this study, among of which has been classified as mild NPDR (n= 1), moderate NPDR (n= 9), severe NPDR (n= 27), and PDR (n= 34). Severe NPDR group had older age distribution at range 51-60 years old (n= 18, 66.7%, p = 0.001). Stage 1 hypertension was found to be dominant in PDR group (n= 18, 66.7%, p = 0.043). Both high total serum cholesterol group (n= 27, 76.5%, p = 0.048) and high fasting blood glucose (n= 27, 79.4%, p = 0.01) were significantly present in patients with PDR. Positive (+1) urine glucose was statistically significant in PDR group. Conclusion: There were several systemic risk factors from laboratory findings correlated in patient with DR in this study, however further study is needed to determine their role for predicting progression and severity of DR.

Abstract

Introduction: Diabetic retinopathy (DR) is a microvascular complication of diabetes and one of the leading causes of blindness. Retinal function loss in diabetic patients is not only caused by microvascular abnormality but also retinal neurodegeneration. Optical coherence tomography (OCT) can detect retinal neural tissue loss caused by diabetes by measuring the retinal nerve fiber layer (RNFL) thickness on the cross-sectional imaging of the retina. This study is to evaluate the changes of peripapillary retinal nerve fiber layer (RNFL) thickness in diabetic retinopathy patients using OCT and compare it to age matched healthy controls. Methods: A cross-sectional study of 16 eyes from 11 diabetic retinopathy patients and 10 eyes from 7 aged matched healthy subjects for control. Patients underwent optic nerve OCT imaging, RNFL  thickness was recorded globally (average thickness) and segmented for superior, inferior, nasal, and temporal quadrants Result: There were no significant difference of  the average RNFL thickness in diabetic retinopathy group compared to healthy subjects. However, at the nasal quadrant, there were a significant increased thickness of RNFL compared to healthy subject (p value=0.009). Conclusion: Optical coherence tomography can be used to detect neurodegeneration progression in diabetic retinopathy patients by quantitatively measuring the peripapillary RNFL thickness. This can be used as a diagnostic and prognostic factor in cases of DR.

Abstract

Introduction: Diabetic Retinopathy (DR) is a common microvascular complication in patients with Diabetes Mellitus (DM) that can cause visual impairment and blindness in adult populations. Retinal microvascular changes, reflecting capillary drop out, non perfusion, and retinal ischemia seen in patients with DM can be assessed not only qualitatively, but also quantitatively with the introduction of a new, non invasive imaging modality Optical Coherence Tomography Angiography (OCTA), avoiding potential advese risks that can occur with the use of dye-injection imaging technique. We quantified retinal microvascular changes in healthy control eyes and Diabetic Retinopathy using OCTA. Methods: A cross sectional study included 13 eyes of 9 patients with DR, consists of 11 eyes with Non Proliferative Diabetic Retinopathy (NPDR) and 2 eyes with Proliferative Diabetic Retinopathy (PDR) and 5 eyes of 5 age-matched controls. Participants were imaged with commercial OCTA device (CIRRUS HD-OCT 5000 Angioplex). We analyzed in the Superficial Capillary Plexus (SCP) the following OCTA parameters : Vessel Density (VD), Foveal Avascular Zone (FAZ) area, and FAZ circularity. Result: Normal eyes had a higher mean VD, FAZ circularity (p >0.05) and lower mean FAZ area ( p <0.05) in the SCP compared with the DR (NPDR + PDR) group. If we excluded the PDR eyes from the analytic data, mean VD and FAZ area were found to be lower in control group, and mean FAZ circularity was higher. However, no quantitative parameters were statistically significant between control group and NPDR group. Conclusion: Microvascular changes in DR can be assessed with the use of Optical Coherence Tomography Angioraphy, which is non invasive and provides high quality of images acquired from the chosen level of retina.

Abstract

Introduction: The incidence of Intraocular Foreign Body (IOFBs) among open-globe injuries ranges from 18% to 41%. In addition to clinical examination at the slit-lamp and indirect ophthalmoscopy, various imaging modalities are valuable for the identification and localization of IOFB. Vision loss can be devastating as a result of endophthalmitis, retinal detachment or proliferative vitreoretinopathy (PVR). Timely and appropriate management often leads to favorable anatomic outcomes with restoration of good visual function in the majority of cases. This case report presents the clinical and diagnostic finding, management, outcomes and further plan of the patients with posterior segment IOFB. Purpose: To report some cases of posterior segment intraocular foreign body. Case report: Three patients with history of ocular  trauma of the right eye that happened at workplace. All of patients were men in age range 20-55 years old . There were also loss of vision, pain, redness, and from ophthalmological examinations revealed two scleral injuries and one corneal injury that suggest an IOFB in posterior segment. Two patients were suggest endophtalmitis before operation. The plain x ray film examination showed intraocular foreign body in the right eyes. The Ultrasonography (USG) examination also showed intraocular foreign body in the right eyes. All of patient were underwent pars plana vitrectomy. Durante operation 2 of 3 patients were succeed to extract IOFB from the posterior segment, while one patient was not. Conclusion: Preoperative, intraoperative and postoperative management should be done correctly for some cases of IOFB. Prompt treatment and full assessment of patients is important to provide good prognosis.

Abstract

ABSTRACT Introduction: To observe the number and  presentation of retinal redetachment after primary reattachment treatment in a national eye  center. Methods:  This study was designed for ob- servational-descriptive of the medical record  from April 2011  to March 2012.  Selected cases were identified on the secondary retinal surgery for retinal reattachment followed the failure of the primary treatment. Cases were then classified into 4 groups based on the primary reattach- ment procedure: pneumatic retinopexy (PR), scleral buckle (SB), pars plana vitrectomy (PPV), and combined SB with PPV. Furthermore, in the group of PPV and SB+PPV  were then divided into 3 subgroups based on the intraocular tamponade: SF6  gas, silicone oil, and heavy  silicone oil. Results:  At one-year followed-up data, the presentation retinal redetachment was 7.1%, relative to the sex female (26%) was less than  male (74%) with the most common age  group was 41-50  years-old. Regarding with primary reattachment treatment, cases  of retinal redetachment after pneumatic retinopexy was 6%,  the  scleral buckle was 16%,  pars plana vitrectomy was 29%, and  combined sclera buckle with pars plana vitrectomy was 48%. Con- clusions: Rates of retinal redetachment after primary reattachment treatment varied from 6% to 48%, that were  performed by combined scleral buckling and  pars plana vitrectomy with or without tamponade silicone oil. Keyword : Retinal redetachment, pars plana vitrectomy, scleral buckle, silicon oil, intraocular gas

Abstract

Background: Retinal nonperfusion area assessment in retinal vein occlusion (RVO) patient is valuable to evaluate progression, therapy, and prognosis. Noninvasive method such as red free fundus photograph that has been processed using a specific program are expected to have correspondence with fundus fluorescein angiography (FFA), as the gold standard in assessing nonperfusion area. Methods: A cross-sectional study. 24 pairs of red free image and FFA were collected from RVO patients at Cicendo Eye Hospital selective consecutively admission from March until August 2013. Red free digital image processing was done by a technician and nonperfusion area was deliminated by a vitreoretina expert. Statistical analysis Wilcoxon signed ranks test was used to compared the nonperfusion area, Spearman correlation test to assessed the correlation coefficient, and the overlapping ratio was used to assessed the morphology suitability between two method. Results: Nonperfusion area analysis between two method showed no statistical difference (Zw 4.257, p=0.161, Wilcoxon) and have a high correlation(r>0.988, p=0.000, Spearman). Suitability was determined by the ratio of morphology overlap that approaches one (overlapping ratio was 0.89). Conclusion: Red free fundus photograph digital image processing has compatibility with the FFA in assessing nonperfusion area. It’s a noninvasive method, easy, safe, and can be used as an alternative for assessing nonperfusion area of RVO patients. Keywords: Nonperfusion area, red free fundus photograph, FFA, retinal vein occlusion
