"Tujuan: Mengetahui pengaruh fotokoagulasi laser terhadap kadar Hypoxia-inducible Factor-1α (HIF-1α) vitreus dan kadar Intercellular Adhesive Molecule-1 (ICAM-1) vitreus pada Retinopati Diabetik Proliferatif. Metode: Penelitian ini adalah uji klinis acak terbuka. Desain penelitian adalah uji klinis acak terbuka. Dua puluh dua mata dirandomisasi menjadi 2 kelompok, yaitu yang mendapatkan fotokoagulasi laser panretinal 1-2 minggu pre-vitrektomi dan kontrol. Kadar HIF-1α dan ICAM-1 dihitung menggunakan enzyme-linked immunosorbent assay (ELISA). Central macula thickness (CMT) diukur saat baseline, pre-vitrektomi, follow-up 2, 4, dan 12 minggu paska vitrektomi. Hasil: Analisis hasil didapatkan rerata kadar HIF-1α vitreus (dalam ng/mL) pada kelompok kontrol dan fotokoagulasi laser masing-masing 0,152±0,015 dan 0,164±0,033 sedangkan kadar ICAM-1 vitreus(dalam ng/mL) adalah 17,840±14,140 dan 27,027±10,452. Tidak terdapat perbedaan bermakna rerata kadar HIF-1α dan ICAM-1 vitreus serta CMT di setiap waktu follow up antara kedua kelompok. Terdapat korelasi antara kadar HIF-1α dan HbA1c (r=0,463, p=0,03). Pengukuran CMT pre-vitrektomi dan kadar HIF-1α vitreus pada penelitian ini mempunyai korelasi positif pada kedua kelompok (r = 0,447 dan r = 0,32). Simpulan: Fotokoagulasi laser 1-2 minggu pre-vitrektomi tidak menyebabkan kadar HIF-1α dan ICAM-1 yang lebih rendah dibandingkan dengan yang tidak mendapatkan laser. Kadar HIF-1α vitreus berkorelasi dengan tebalnya CMT, sedangkan kadar ICAM-1 vitreus tampak tidak berhubungan. Kontrol glikemik yang lebih buruk pada kelompok fotokoagulasi laser mempengaruhi hasil dari kadar HIF-1α maupun ICAM-1 vitreus. ......Purpose: to determine the effect of pre-treatment of laser panretinal photocoagulation (PRP) before vitrectomy to Hypoxia-inducible Factor-1α (HIF-1α) and Intercellular Adhesive Molecule-1 (ICAM-1) in the vitreous fluid of patients with diabetic retinopathy proliferative. Methods: This is post-test only randomized clinical trial open label study. Twenty two eyes were recruited, and 11 eyes had pre-treatment of PRP pre-vitrectomy and other 11 eyes were served as control. HIF-1α and ICAM-1 were measured by enzyme-linked immunosorbent assay (ELISA). At the beginning of PRP and just before vitrectomy (1-2 week after PRP), and at the time of follow-up of 2,4, and 12 week after vitrectomy, central macular thickness (CMT) was measured. Results: Mean of HIF-1α(ng/mL) were 0,152±0,015 and 0,164±0,033in control and photocoagulation group, respectively. Mean of ICAM-1(ng/mL) were 17,840±14,140 and 27,027±10,452. There were no statistically significant differences in the comparison of both HIF-1α and ICAM-1 in each group and CMT at each time of follow up. The positive correlation between ICAM-1 in the vitreous body and HbA1c was clinically significant (r=0,463, p=0,03). The positive correlation between both level of HIF-Iα the vitreous body of both groups and CMT was found (r = 0,447 dan r = 0,32). Conclusion: Laser photocoagulation 1-2 weeks before vitrectomy did not cause lower concentration of vitreous level of HIF-1α dan ICAM-1. Glycemic control status that worse in laser photocoagulation group could influence the level of HIF-1α and ICAM-1 vitreus."

"Tujuan tesis ini adalah mengetahui pengaruh laser fotokoagulasi panretinal 532 nm durasi 20 ms dosis tunggal, 100 ms dosis tunggal dan 100 ms-3 sesi terhadap ketebalan makula sentral (KMS). Desain penelitian adalah uji klinis acak terkontrol tersamar ganda. Tiga puluh tiga mata yang memenuhi kriteria inklusi dirandomisasi untuk mendapatkan laser 20 ms dosis tunggal atau 100 ms dosis tunggal atau 100 ms-3 sesi. Keluaran primer adalah KMS yang diukur menggunakan time-domain Optical Coherence Tomography pada baseline, 4 minggu dan 8 minggu pasca laser. Analisis hasil didapatkan rerata ( + SE) KMS baseline kelompok 100 ms, 20 ms dan 100 ms-3 sesi berturut-turut adalah 212,18 + 12,18 μm; 199,18 + 12,18 μm; 215,36 + 12,18 μm. Empat minggu pasca laser, KMS berturut-turut meningkat menjadi 232,09 + 18,63 μm; 206,27 + 18,63 μm; 254,09 + 18,63 μm. Delapan minggu pasca laser, KMS meningkat pada kelompok 100 ms dan 20 ms (237,90 + 17,47 μm; 208,27 + 17,47 μm), namun menurun pada kelompok 100 ms-3sesi (252,36 + 17,47 μm).......The purpose of this study was to determine the effect of panretinal laser photocoagulation 532 nm of 20 ms duration single session (SS), 100 ms SS and 100 ms (3 session) toward central macular thickness (CMT). The study design was a double-blind, randomized controlled clinical trial. Thirty-three subjects who met inclusion criteria were randomized to receive 20 ms SS laser or 100 ms SS or 100 ms (3 session). Primary output was CMT, measured by time-domain Optical Coherence Tomography at baseline, 4 weeks and 8 weeks post-laser. Results showed mean ( + SE) CMT at baseline from 100 ms SS group, 20 ms SS and 100 ms-3 session were 212.18 + 12.18 μm; 199.18 + 12.18 μm; 215.36 + 12.18 μm respectively. Four weeks after laser, CMT was increased to 232.09 + 18.63 μm; 206.27 + 18.63 μm; 254.09 + 18.63 μm respectively. Eight weeks post laser, CMT was increased in 100 ms SS and 20 ms SS (237.90 + 17.47 μm; 208.27 + 17.47 μm), but decreased 100 ms-3session group (252.36 + 17.47 μm)."
