"ABSTRAK
Katarak merupakan sebab kebutaan utama di seluruh dunia. Sebab timbulnya katarak, baik katarak senilis (KS), maupun katarak diabetik (KD) belum jelas. Oleh karena itu pencegahan dan pengobatannya belum dapat dilaksanakan dengan sempurna.
Tujuan penelitian ini ialah untuk mengetahui apakah radikal bebas, diukur sebagai peroksida lipid (PL), berperan pada timbulnya KS dan KD. Untuk mencapai tujuan ini dibandingkan kadar FL serum kelompok KS1 KD dan kontrol nonkatarak (K). Dibandingkan pula kadar FL aqueous humor (AO) kelompok KS dan KD. Darah kelompok KS dan KD diperoleh dari pasien sebelum operasi katarak, sedangkan A0 sewaktu operasi oleh dokter bedah mata. Kadar PL ditetapkan dengan Cara Stringer, berdasarkan pengukuran malondialdehida (MDA), hasil penguraian PL.
Kelompok KS terdiri dari 51 orang dengan umur 43-85 tahun ( X = 60,93, SP = 8,84); kelompok KD terdiri dari 22-orang dengan umur 42-75 tahun (X = 61,68, SD = 9,74), sedangkan kelompok K terdiri dari 24 orang dengan umur 40-82 tahun (X = 58,42, SB = 13,84). Tidak ada perbedaan bermakna antara umur kelompok KS, KD dan K. Oleh karena lebih dari 30. (16 orang) dari kelompok KS berumur kurang dari 60 tahun, kelompok ini lebih tepat disebut kelompok non-diabetik.
Hasil PL darah KS = 7,23 ± 2,31, KD = 7,24 ± 1,61 dan K 6,19 {- 1,91 (X -4. SB) vmol/L, tanpa perbedaan bermakna antara ketiga kelompok (p 0,05). Kadar PL AO KS ( 2,54 t 1,98 vmol/L, n = 12) dan KD ( 2,29 ± 1,00 vmol/L, n - 4) juga tidak menunjukkan perbedaan bermakna (p > 0,05). Tidak ada korelasi antara kadar PL darah dan AG . Dari data tersebut tidak dapat disimpulkan bahwa PL berperan pada timbulnya KS dan KD, namun belum dapat disingkirkan kemungkinan terganggunya metabolisme oksidatif pada tingkat lensa.
Kami sarankan teknik pengambilan An disempurnakan dan penetapan PL AO pada katarak non-diabetik dan KD( IDDM dan NIDDM) dilakukan dengan sampel yang lebih banyak.

ABSTRACT
Lipid Peroxide Level In Blood And Aqueous Humor Of Patients With Senile And Diabetic CataractCataract is the main cause of blindness all over the world. The cause of both senile and diabetic cataract are still unknown; consequently no appropriate therapy and prevention of cataract formation are presently known.
The aim of this study is to get information on the possible role of free radicals, measured as lipid peroxide (LP), on the formation of senile (SC) and diabetic cataract (DC).
We compaired the serum LP level of patients with SC, DC and noncataract controls; also the LP level of aqueous humor (AO) of patients with SC and DC. Blood of cataract patients was drawn before the cataract operation, while AO was collected during the operation by the ophthalmic surgeon. Estimation of LP was performed by the method of Stringer, which measured , the malondialdehyde concentration.
The SC group consisted of 51 persons, aged 43--85 years (X - 60.93, SD = 8.84); the DC group of 22 persons aged 42-75 years (X = 61.69, SD = 9.74) and the control group (C) of 24 noncataractous persons. As more than 30% of the SC group were younger than 60 years, this group should be more appropriately classified as the nondiabetic cataract group. The blood LP level of the SC, DC and C group were 7.2,E - 2.31, 7.24 ± 1.61 and 6.19 ± 1.91 ( X ± SD) vmol/L respectively. These results showed no significant difference. The aqueous LP levels of the SC ( 2.54 ± 1.9B, n = 12) and the DC ( 2.29 ± 1.00) group were also not significantly different. No correlation was found between the LP levels in blood and AO of the SC and DC patients. The results mentioned above did not show that LP were involved in the development of SC and DC and that a systemic disturbance in oxidative metabolism existed in the SC and DC patients. However, an increase of oxidative metabolism or defect in the anti-oxidative mechanism at lens level could be present.
We propose to improve the AO sampling technique and estimate the AO LP levels, using a larger number of samples from non diabetic and diabetic (IDDM and NIDDM) cataract patients.

"Pendahuluan: Glaukoma primer sudut tertutup akut (GPSTA) adalah penyakit mata yang disebabkan oleh tertutupnya seluruh anyamari trabekulum oleh pangkal iris secara mendadak. GPSTA menycbabkan kcbutaan yang bersifat permanen. Penanganan cepat dan segera adaiah mutlak untuk mencegah kebutaan. Penatalaksanaan awal adaiah menurunkan TIO secepat mungkin dengan pemberian medikamentosa gabungan inisial atau parasentesis yang dilanjutkan dngan Iridektomi Perifer Laser (IPL). Proses infiamasi ras Asia Iebih berat dan TGP-B2 dan TNF-a merupakan petanda iskemia dan inflamasi.
Tujuan: (1) Menilai rcspons parasentesis pada pasien GPSTA; (2) Membandingkan kadar TGP-B2 dan TNF-a humor akuos pasien GPSTA dengan pasien katarak; (3) Menilai efek pemberian deksametason terhadap kadar TGP-B2 dan TNF-a humor akuos pasien GPSTA; (4) Memperhitungkan faktor risiko terhadap suksesnya IPL pada pasien GPSTA.
Bahan dan Cara: Penelitian ini merupakan studi prospektif dengan uji pra-pasca untuk menilai respons parasentesis dan studi komparatif belah lintang untuk membandingkan kadar TGP-B2 dan TNF-a humor akuos pasien GPSTA dengan pasien katarak. Untuk menilai efek deksametason terhadap kadar TGF-B2 dan TNF-a humor akuous dilakukan studi ldinis acak terkontrol tersamar ganda. Untuk mencari faktor risiko yang mempengaruhi keberhasilan IPL dilakukan perhitungan bivariat, dilanjutkan regresi logistik. Subjek penelitian adalah semua pasien GPSTA dengan Iama serangan di bawah 1 bulan.
Hasil penelitian analisis pada 45 mata pasien GPSTA yang menjalani parasentesis, TIO awal turun. Kadar TGF-B2 dan TNF-a humor akuos pasien GPSTA, rnasing-masing, 4 kali dan 3 kali dari pasien katarak. Setelah IPL dan randomisasi antara kelompok kontrol dan deksametason, deksametason menurunkan kadar TGF-B2 dan TNF-a pasien GPSTA secara tidak signifikan. Faktor risiko yang mempengaruhi keberhasilan IPL adalah respons TIO pascaparascntesis dan luas SAP. Inflamasi tidak berpengaruh terhadap IPL, tetapi sekuele yang diakibatkannya mempengaruhi tindakan tersebut, yaitu SAP. Selain itu, faktor respons terhadap tindakan parasentesis juga turut berperan secara signifikan.
Kesimpulan: Tindakan parasentesis menurunkan TIO awal pasien GPSTA. Kadar TGF-B2 dan TNF-a humor akuos tinggi pada pasien GPSTA. Pengaruh deksametason menurunkan kadar TGP-B2 dan TNF-a secara tidak signifikan. Keberhasilan tindakan IPL adalah 95% pada pasien GPSTA yang mempunyai respons baik terhadap parasentesis dengan luas SAP di bawah 4 jam. Sebaliknya, bila pasien GPSTA tidak memberi respons baik pascaparasentesis dan luas SAP 9-12 jam, maka keberhasilan IPL hanya 5%.

Introduction: Acute primary angle closure glaucoma (APACG) is an eye disease caused by sudden closure of trabecular meshwork by the iris root. APACG could cause permanent blindness. Rapid management was essential in preventing blindness. Early management of this disease was done by reducing IOP as quickly as possible by the administration of initial combined medications or paracentesis, followed by laser peripheral iridectomy. Inflammatory process in the Asian race was more severe and TGP-B2 and TNF-a. constituted the signs of ischemia and inflammation.
Objective: (1) To evaluate the response to paracentesis in APACG patients; (2) to compare the TGP-B2 and TNF-a levels of aquous humor in APACG patients and cataract patients; (3) to analyze the effects of the administration of dexamethasone on the TGF-B2 and TNF-a levels of aquous humor in APACG patients; (4) to calculate the risk factors against the success of laser peripheral iridectomy in APACG patients.
Material and methods: This study was a prospective study with pre-post tests design to evaluate the response to paracentesis. Cross-sectional comparative study was perfomied to compare the TGF-B2 and TNF-a. levels of aquous humor in APACG patients and cataract patients. To evaluate the effects of dexamethasone on the TGF-B2 and TNF-a levels of aquous humor, a double-mask, randomized controlled trial was performed. To identify the risk factors affecting the success of laser peripheral iridectomy, a bivariate calculation was done, followed by logistic regression calculation. The subjects of the study were all APACG patients with the duration of attack under one month.
Results: Analysis in 45 eyes of APACG patients undergoing paracentesis showed t.hat early IOP decreased by 49%. The TGF-B2 and TNF-a levels of aquous humor in APACG patients were four and three times as high as those in cataract patients respectively. After laser peripheral iridectomy and randomization between the control group and dexamethasone group, it showed that dexamethasone reduced the TGF-B2 and TNF-a levels of APACG patients insignificantly. The risk factors affecting the success of laser peripheral iridectomy was the response to IOP after paracentesis and the size of peripheral anterior synechiae (PAS). Inflammation did not affect laser peripheral iridectomy; however, the sequele that it caused affected the intervention, i.e. PAS. In addition, the response factor inparacentesis also played a significant role.
Conclusion: Paracentesis could reduce early IOP in APACG patients. The TGF-B2 and TNF-a levels of aquous humor were high in APACG patients. The effect of dexamethasone in reducing the TGF-B2 and TNF-a levels was not significant. The success rate of laser peripheral iridectomy was 95% in APACG patients with good response to paracentesis with the size of PAS under 4 hours. By contrast, if APACG patients did not give a good response to paracentesis and the size of PAS was 9-12 hours, the success rate of laser peripheral iridectomy was only 5%."
