Abstract

Introduction Retinopathy of prematurity (ROP) is the leading cause of blindness in newborn babies worldwide. The benefit of anti-oxidant was investigated for ROP cases by assessing its effect on the oxidative stress of the tissues. Glutathione is a primary endogenous in human body and its supplementation has been discovered for its benefits towards some ocular diseases. This study aims to understand the effect of glutathione on oxidative stress marker, serum Malondialdehyde (MDA), in ROP rat models.Materials and methods This was an experimental study with post test only controlled group design. Sixteen Wistar rats that met our study criterias were divided into two groups, study group and control group. The study group were exposed to 95% oxygen for 4 hours / day followed by normoxic laboratory condition for 20 hours. Glutathione 1.5 mg / day were injected intramuscularly to rats in study group. The control group was exposed to 95% oxygen followed by normoxic laboratory condition with the same manner, and did not received glutathione. This cycle was repeated for 14 days. Both groups were settled in a room temperature settings on days 15-22. Serum sampel was collected from retroorbital vein. The malondialdehyde level was analyzed using MDA analyser kit.Results MDA level was found significantly higher in study group compared to control group (546.99 ng/ml vs 201.51 ng/ml, respectively, p 0,001).Conclusion Our study demonstrated a higher MDA levels in ROP rat models given glutathione injection compared to the control group.

Abstract

Latar belakang: Perkiraan tajam penglihatan pasca bedah katarak sangat diperlukan untuk memberikan informasi kepada pasien katarak sebelum operasi.Retinometer dapat mengukur potensial visus pasca bedah katarak pada kondisi lensa yang keruh.Ketepatan hasil pemeriksaan retinometri diharapkan dapat membantu menentukan prognosis penderita katarak. Penelitian ini bertujuan untuk mengetahui perbedaan retinometri prabedah dengan pasca bedah berdasarkan derajat katarak senilis.Metode: Disian penelitian adalah pre post design yang dilakukan pada pasien katarak. Populasinya adalah penderita katarak senilis dengan sample yang memenuhi kriteira inkulsi dan eksklusi. Subjek yang memenuhi kriteria inklusi dilakukan pemeriksaan retinometer prabedah dengan pupil lebar dan pemeriksaan retinometer pasca bedah. Derajat katarak diklasifikasikan menurut Japanese cooperative cataract epidemiology study group system (JCCES). Derajat 1 dan 2 dimasukan dalam kelompok 1 sedangkan untuk derajat 3 dan 4 dimasukan dalam kelompok 2. Data dianalisis menggunakan t-test.Hasil: Didapatkan 59 pasien katarak dengan rerata perbedaan hasil retinometri prabedah dengan pasca bedah pada kelompok 1 adalah 0,05 (p=0,04) sedangkan rerata perbedaan hasil retinometri pada kelompok 2 sebesar 0,23 (p=0,001). Terdapat perbedaan bermakna antara hasil retinometri pra bedah dan retrinometri pasca bedah pada kelompok 1 dan 2. Semakin tinggi derajat katarak ,perbedaan tersebut semakin besar.Simpulan: Semakin tinggi derajat katarak, retinometri prabedah mempunyai nilai yang semakin rendah dibandingkan dengan retinometri pasca bedah. Kata kunci: Retinometri, katarak

Abstract

Background: Glaucoma is a group of diseases consisting of optic neuropathy characterized by damage to the retinal nerve fibers and narrowing of the visual field accompanied by increased intraocular pressure as a risk factor. Vision loss in glaucoma patients is considered as a separate stressor. Besides that, decrease visual function can also cause a person to lose his job and loss of social functions. This can trigger anxiety to depression.Objective: To analyze the correlations between the severity of disease with anxiety levels in glaucoma patients.Methods: This was an observational analytic study with a cross-sectional design. Subjects were taken by consecutive sampling with inclution criterias were patients with moderate or severe glaucoma, able to follow the interview process and 30-80 years old. The exclusion criteria of this study were patients who was taking anti-anxiety, antidepressant, or antipsychotic drugs and having other serious / chronic disease such as heart disease, diabetes, or hypertension. Anxiety level was assessed based on the Taylor Manifest Anxiety Scale (TMAS) questionnaire. Analysis of the data using the Spearman Correlation test.Results: Sixty five glaucoma patients who underwent treatment in out patients department dr. Kariadi hospital were involved in this study.  A significant correlation was obtained between the severity of glaucoma and the level of anxiety (p = 0.004). Strong statistical correlation between variables included in the weak category (0.357). The highest anxiety level in glaucoma patients was moderate anxiety level (64.6%), followed by mild anxiety level (23.1%) and severe anxiety level (12.3%).Conclusion: There were significant correlation between the severity of the disease and the level of anxiety in glaucoma patients.

Abstract

ABSTRACT Background:Intra ocular pressure (IOP) elevationis one of topical steroids’ side effects. Corticosteroid will initiate matrix metalloproteinase cascade that leads to extra cellular matrix (ECM)of trabecular meshwork (TM) turnover(remodeling) and its acumulationin TM. Objective: To analyze the reversibility of ECM TM in Wistar rat after discontinuation oftopical prednisolone1% at different periode(14 days and 28 days). Methods:This was an experimental study with post test only controlgroup design. Total samples of 28 rats were divided into 4 groups: Treatment groups 1 was treated with  topical prednisolone for 28 days, and was terminated 14 days after discontinuation of the drug.Treatment goups2 was treated topical prednisolone for 28 days and was terminated28 days after discontinuation of the drug. Control 1 was treated withtopical prednisolone for 28 days, and Control 2 was treated with topical saline for 28 days and terminated without periode of discontinuation. Histopathological grading score was used to evaluate ECM TM deposition. Mann-Whitney test and Kruskal-Wallis test were used to analyze the data. Result: Deposition of ECM in TM was not statistically different intreamentgroup 1 and treatment group 2 (p>0.05). Deposition of ECM in TM were statistically differentbetween treatment group 2 and control group 1 (p<0.05). Comparative test showed p<0.001,which means that there was a change in the  thickness of ECM after discontinuation of instillation. Conclusion: ECM TM was thinner in the experimental animals with a longer duration of topical prednisolondiscontinuation, which demonstrate that maintenance remodeling of ECM was happen.

Abstract

Background: Ethambutol-induced optic neuropathy (E-TON) is one of the most common optic neuropathies, especially in developing countries with an increasing rate of Tuberculosis (TB). Various outcomes of visual impairment that may lead to permanent visual loss makes it imperative to prescribe supplementation to prevent E-TON. Zinc supplementation is suggested as one of many to prevent E-TON given that ethambutol is a Zn chelator.Purpose: To analyze the apoptosis rate of retinal ganglion cell (RGC) in Wistar rats given ethambutol and Zinc supplementation.Methods: Experimental analysis research. True – experimental design and post-test only using Wistar rats. Subjects were divided into 2 groups, treatment grup was given Ethambutol and Zn and control group was given ethambutol without Zn for 30 days. Assessment of apoptosis rate was concluded by an anatomical pathologist with histopathological scoring using Hematoxylin Eosin staining. Differences between two grups were statistically analyzed using Mann Whitney U test, (Signifikan p <0,05).Results: From Distribution of rate apoptosis in treatment group was found 28.6% without apoptosis, 71.4% score 1 and no score > 1. There was a significantly different in apoptosis retinal ganglion cell between two grups (p= 0.015).Conclusion: The rate of retinal ganglion cell apoptosis was lower in rats treated ethambutol with Zn than without Zn.
