Proliferative vitreoretinopathy  (PVR) pada ablasio retina rhegmatogen (ARR) menurunkan tingkat keberhasilan anatomis dan fungsional. Transforming growth factor-β (TGF-β) merupakan pro-fibrotik yang berperan penting dan dapat menjadi target terapi dan masih belum ada data mengenai TGF-β3 pada PVR. Penelitian ini bertujuan menguji kadar TGF-β2 dan TGF-β3 pada kasus PVR A dan B.  Penelitian ini berdesain potong lintang pada pasien ARR PVR A dan B yang menjalani vitrektomi di RSCM Kirana. Sampel vitreus diambil intra-operasi dan diperiksa di protein total, TGF-β2 dan TGF-β3 dengan metode ELISA. Didapatkan 20 sampel; 10 mata untuk PVR A dan 10 untuk PVR B. Tidak didapatkan perbedaan bermakna untuk karakteristik kedua grup maupun berdasarkan TGF-β2 dan TGF-β3. Secara umum didapatkan level TGF-β2 yang lebih tinggi pada PVR A dan B namun tidak terdapat perbedaan signifikan (p>0,05). Didapatkan korelasi negatif (Spearman r-0,468)  antara TGF- β2 dengan TGF- β3 pada seluruh grup PVR (p=0,037) namun tidak didapatkan korelasi yang signifikan per grup PVR. Tidak ditemukan perbedaan bermakna antara TGF- β2 dan TGF- β3 dengan primary attachment rate. Tidak didapatkan perbedaan bermakna antara TGF- β2 dan 3 pada ARR yang terjadi sebelum atau sesudah 14 hari namun ditemukan tren rasio TGF- β2/protein total yang semakin rendah 14 hari pasca ARR Studi ini merupakan studi pertama yang membandingkan kadar TGF- β2 dan TGF- β3 pada pasien dengan PVR A dan B. Secara tren, ditemukan kadar TGF-β2 yang lebih tinggi pada ARR dengan PVR  B dibanding A dan kadar TGF-β3 yang lebih rendah pada ARR dengan PVR B dibanding A. ......Proliferative vitreoretinopathy (PVR) in rhegmatogenous retinal detachment (RRD) reduces anatomical and functional success rate. Transforming growth factor-β (TGF-β) is a pro-fibrotic that plays an important role and can be a therapeutic target and there is still no data on TGF-β3 in PVR. This study aims to examine the levels of TGF-β2 and TGF-β3 in cases of PVR A and B. This study used cross-sectional design in ARR PVR A and B patients who underwent vitrectomy at RSCM Kirana. Vitreous samples were taken intra-operatively and examined for total protein, TGF-β2 and TGF-β3 using ELISA. A total of 20 samples were obtained; each 10 eyes for PVR A and 10 for PVR B. There were no significant differences in the characteristics of the two groups or based on TGF-β2 and TGF-β3. In general, higher TGF-β2 levels were found in PVR A and B but there was no significant difference (p>0.05). A negative correlation (Spearman r-0.468) was found between TGF-β2 and TGF-β3 in all PVR groups (p=0.037) but no significant correlation was found per PVR group. There was no significant difference between TGF-β2 and TGF-β3 with primary attachment rate. There was no significant difference between TGF-β2 and 3 in ARR that occurred before or after 14 days, but a trend was found in the ratio of TGF-β2/total protein that was getting lower ≥14 days after ARR. This study is the first study to compare TGF-β2 and TGF-β3 levels in patients with PVR A and B. In terms of trend, higher TGF-β2 levels were found in ARR with PVR B compared to A and lower TGF-β3 levels in ARR with PVR B compared to A.

Latar Belakang: Silicone oil (SO) merupakan salah satu substitusi vitreus yang digunakan pasca vitrektomi pars plana (VPP) dalam manajemen ablasio retina rhegmatogen. Beberapa komplikasi penggunaan SO meliputi katarak, peningkatan tekanan bola mata, emulsifikasi, keratopati hingga menurunnya ketebalan dan densitas vaskular makula. Tujuan: Mengetahui perubahan ketebalan makula sentral serta densitas vaskular pleksus superfisial pada pasien ablasio retina rhegmatogen pasca VPP dengan tamponade SO. Metode: 41 pasien ablasio dianalisis dalam studi ini yang menggunakan dua desain: observasional prospektif tanpa pembanding untuk membandingkan efek tamponade SO minggu-1 dengan minggu-4 dan potong lintang untuk membandingkan mata kontralateral dengan minggu-1 pasca tamponade SO. Hasil: Central subfield thickness (CST), superficial vascular density (SVD) serta superficial perfusion density (SPD) pada minggu-1 lebih rendah dibandingkan mata kontralateral (p<0,001). Pada minggu-4 pasca tamponade SO ditemukan peningkatan CST, SVD, SPD dibandingkan minggu-1 meskipun tidak signifikan secara statistik. Pada analisis tambahan, didapatkan usia diatas 50 tahun mengalami kecenderungan penurunan SVD (p 0,033) dan SPD (0,011) dibandingkan kelompok usia muda. Kesimpulan: Tidak didapatkan penurunan ketebalan makula sentral dan densitas vaskular pleksus kapiler superfisial makula di minggu-4 pasca PPV dengan SO. Didapatkan ketebalan makula sentral dan densitas vaskular pleksus kapiler superfisial makula yang lebih rendah di minggu-1 pasca tamponade SO dibandingkan mata kontralateral ......Background: Silicone oil (SO) is one of the vitreous substitutes used after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) management. Complications arising from SO include cataracts, increased ocular pressure, emulsification, keratopathy, and decreased macular thickness and vascular density. Objective: To determine changes in central macular thickness and superficial vascular density in RRD patients after PPV with SO. Method: 41 patients were included in this study, which comprises two designs: a prospective observational without comparison to compare the effect of SO tamponade week-1 with week-4 and a cross-sectional design to compare the contralateral eye with week-1 after SO tamponade. Results: Central subfield thickness (CST), superficial vascular density (SVD), and superficial perfusion density (SPD) were lower at week 1 after PPV with SO compared to the contralateral eye (p<0.001). At week 4 after PPV with SO, there was an increase in CST, SVD, and SPD compared to week 1, although not statistically significant. In additional analysis, we found that those aged over 50 had tendencies toward decreased SVD (p 0.033) and SPD (0.011) compared to the younger age group. Conclusion: There was no reduction in central macular thickness or superficial vascular density at week 4 after PPV with SO in RRD patients. Central macular thickness and superficial vascular density were lower on week 1 after SO tamponade compared to the contralateral eye.
