Abstract

Introduction: Severe systemic hypertension in chronic kidney disease can cause significant damage to the eye. Although hypertensive retinopathy is a well-known complication, hypertensive optic neuropathy and choroidopathy are much less common. The aim of this study is to report retinal manifestation in young patient with chronic kidney disease. Method: A 26-year-old man with underlying disease chronic kidney disease (CKD) gr-V underwent bilateral bullous exudative retinal detachments. Retinal arteriolar narrowing, vascular tortuosity, arteriovenous nicking, optic disc swelling, retinal haemorrhage, elschnig spot, siegrist streak were identified in both eyes. Blood pressure was 200/140mmHg with visual acuity 0,5/60 OU. The patient was diagnosed with bilateral hypertensive retinopathy and choroidopathy with bulous exudative retinal detachments. Results: After antihypertensive treatment, visual acuity improved, but the exudative retinal detachments and retinal hemorrhages reduced. A patient with those findings should be considered as having hypertensive retinopathy and choroidopathy and treated as soon as possible because of the poor prognostic. Conclusion: Hypertensive choroidopathy is a rare finding associated with acute increases in blood pressure. When the choroid is associated, the hypertensive event is often more acute and associated with increased morbidity. It is necessary to obtain fundus exam in any patient with elevated blood pressure and concomitant vision complaints. Therefore, screening hypertensive patients involves close collaboration between internist and ophthalmologist.

Abstract

Introduction: To report the profile of patients with floaters as a subjective complain in Saiful Anwar Hospital from July 2012 until June 2013. Methods: an observasional descriptive study was conducted, collecting data on gender, age, subjective complain (floaters, flashes and subjective vision reduction), best corrected visual acuity and diagnose from patient’s medical record. Result: 169 patients (215 eyes) were included in this study. Female patients contributed a higher percentage than male with mean of age was 49 years old. The subjective complain was floaters (67%), floater with blurred vision (22%), floater with flashes (6%) and patients with floaters, flashes, and blurred vision was 5%. Myopia was the most common refraction problem. Diagnose recorded from this study were posterior vitreous detachment (PVD) (34%), no abnormalities (13%), PDR (10%), RRD (9%), peripheral retinal degeneration (14%) retinal break (6%), corpus vitreous degeneration (3%), vitreous haemorhage (3%), posterior uveitis (2%) and others (6%). Conclusion: The most common cause of floaters is PVD. Even it is usually a save condition but there are some condition with floater as a subjective complain which is threatening vision, so accurate eye examination from anterior to posterior segment were needed.

Abstract

Komplikasi vaskuler pada diabetes mellitus (DM) menimbulkan keadaan hipoksia yang berlanjut pada proses angiogenesis yang dapat dicegah dengan antiioksidan diantaranya caffeic acid phenethyl Ester (CAPE). Penelitian ini bertujuan untuk mengetahui efek pemberian CAPE terhadap ekspresi endoglin pada HUVECs yang dipapar glukosa tinggi. Penelitian ini menggunakan desain analitik eksperimental pada HUVECs primer yang dipapar glukosa tinggi. HUVECs dibagi menjadi 5 kelompok yaitu: 1. HUVECs+DMSO (kontrol negatif), 2. HUVECs+glukosa 22 mM+DMSO (kontrol positif), 3. HUVECs+glukosa 22 mM+CAPE 3 µM+DMSO 4. HUVECs+glukosa 22 mM+CAPE 10 µM+DMSO, 5. HUVECs+glukosa 22 mM+CAPE 30 µM+DMSO. Inkubasi dilakukan selama 48 jam pada suhu 37°C, lalu dilakukan pengecatan imunositokimia menggunakan antibodi endoglin. Ekspresi endoglin diamati dengan mikroskop cahaya 400x, endoglin tervisualisasi berwarna coklat. Didapatkan perbedaan efek CAPE  di antara kelompok perlakuan terhadap ekspresi endoglin pada HUVECs yang dipapar glukosa tinggi (ANOVA p=0,000). Ekspresi endoglin pada tiap kelompok didapatkan perbedaan signifikan (Tukey test, p<0,05), kecuali antar kelompok 1 dan 5 tidak didapatkan perbedaan signifikan (Tukey test, p>0,05). Dengan Person test didapatkan korelasi positif signifikan antara pemberian CAPE dengan ekspresi endoglin pada HUVECs yang dipapar glukosa tinggi (r=-0,839; p=0,000). Pemberian CAPE dapat menurunkan ekspresi endoglin pada HUVECs yang dipapar glukosa tinggi.Kata Kunci: Caffeic acid phenetyl ester, endoglin, HUVECs

Abstract

Diabetic retinopathy is a leading cause of blindness in industrial world and is rapidly becoming an important cause in developing countries. Many factors related with theseverity of diabetic retinopathy, such as HbA1c and serum lipid. The study wants to know whether those factors have any  correlation with the severity of diabetic retinopathy or not. The objective this study was to determine the correlation between HbA1c and serum lipid with the severity  of diabetic retinopathy. An analytic cross sectional observational research had been done at Saiful Anwar hospital. The samples (diabetic retinopaty patients) were taken with consecutive sampling. These patient underwent funduscopy, fundus photography, laboratory examination including HbA1c, serum lipid (total serum cholesterol, LDL, HDL, triglycerides), and blood glucose. These patient were questioned about risk factors previously determined by the authors. The laboratory findings were thease are compared to the severity of diabetic retinopathy.

Abstract

ABSTRACT Retinal neovascularization is the main problem that causes blindness in many types of eye desease. Neovascularization occurs in ischemic retina, and several important mediators that induce neovascularization is secreted by the surrounding cell and endothelial cell vessels. Matrix metalloproteinase-9 is an enzyme secreted by endothelial cell vessels and plays an important role in the pathogenesis of retinal induce neovascularization. Vascular endothelial cells were cultured and transfected with Matrix Metalloproteinase -9 RNA interference in two doses (100nM or 200nM) and the cells were taken at 24,  48  and  72  hours.  The  expression  of  Matrix  Metalloproteinase  -9  protein  levels  were  examined  by immunocytochemistry, and compared with control group. The data were analyzed with factorial anova. Statistical analysis showed that transfection with different doses of MMP-9 RNAi gave a significant different effect on MMP-9 expression (p-value &lt; 0.05), while exposure time did not give significant difference (p-value &lt; 0.05). This in-vitro study indicated that transfection  of  MMP-9  RNAi  with  dose  200nM  reduced the  expression  of  MMP-9  by  50%  compared  to  the  control. Because exposure time was not significant, the lowest expression of MMP-9 can be achieved by transfecting MMP-9 RNAi 200nM for 24 hours. This is the first study that demonstrates the effectiveness of RNA interference mediated targeting  of MMP-9 to reduce the MMP-9 expression in vascular endothelial cell lines Key Words  : Matrix Metalloproteinase -9 - RNA interference - vascular endothelial cell lines.
