Background Intravitreal silicon oil removal surgery can cause mild-to-moderate postoperative pain and discomfort in most patients. Postoperative pain can be managed by using many methods, including a local anesthetic drug. One of the common local anesthetic drugs is 0.5% bupivacaine. The application techniques also vary, such as subconjunctival application. It was a good alternative for postoperative analgesia in the ophthalmic surgery because of its minimal risks and complications. The purpose of this research was to measure the effectiveness of subconjunctival 0.5% bupivacaine for postoperative analgesia in silicon oil removal surgery. Method This was a double-blind randomized clinical study in patients undergoing elective intravitreal silicon oil removal surgery at Cipto Mangunkusumo Hospital. Thirty consecutive patients, enrolled from October 2016 to February 2017, were randomized to receive subconjunctival 0.5% bupivacaine or subconjunctival placebo (0.9% NaCl) at the end of the surgery. The primary outcome was the pain score 24 hours after surgery, using a 100 mm Visual Analogue Scale (VAS). Intravenous injection of tramadol 50 mg was given if the VAS >4. Secondary outcomes were the time to first analgesic requirement and the incidence of nausea/vomiting. Statistical analysis was conducted to measure the difference between 24 h pain score in the bupivacaine group (B) and that in the placebo group (NS). Result The overall 24 hours' postoperative pain score was significantly different between the bupivacaine group and the placebo group (p=0.001). In the 24 hours after surgery, there were only five patients needing additional analgesia in the placebo group. The time to first analgesic requirement was significantly different between the two groups (p=0.042). Nausea/vomiting only happened in the placebo group with proportions 6% and 3%, respectively. Conclusion Subconjunctival 0.5% bupivacaine was effective for postoperative analgesia in intravitreal silicon oil removal surgery.

Latar Belakang: Vitrektomi pada ablasio retina dapat dilakukan dengan anestesi umum maupun anestesi lokal. Anestesi lokal kerap dipilih atas keunggulannya dalam efisiensi waktu dan biaya. Tujuan: Memaparkan tingkat keberhasilan anatomi dan fungsional vitrektomi dengan anestesi lokal pada ablasio retina rhegmatogen di Divisi Vitreoretina RSCM-FKUI. Metode: Penelusuran retrospektif pada 42 pasien ablasio retina rhegmatogen yang dilakukan vitrektomi dengan anestesi lokal di RSCM-FKUI pada Januari 2017 – Juni 2017.Hasil: Terjadi peningkatan tajam penglihatan pada enam bulan pasca vitrektomi dengan anestesi lokal yaitu visus ?1/60 dari 55% menjadi 77%. Kondisi retina menempel pasca tindakan operasi vitrektomi dengan anestesi lokal sebanyak 93%. Kesimpulan: Tingkat keberhasilan fungsional sebesar 77% dan keberhasilan anatomis 93%.

Background: Endophthalmitis is one of the emergencies in ophthalmology and can cause blindness. The most common cause of endophthalmitis in intraocular surgery is cataract surgery. Immediate diagnosis and treatment can provide optimal final vision. This research aimed to describe the demographic data, and causative microorganisms, as well as the success rate of visual outcome after pars plana vitrectomy (PPV) in post-cataract surgery endophthalmitis in Cipto Mangunkusumo Hospital. Methods: A retrospective descriptive study of post-cataract surgery endophthalmitis underwent vitrectomy in Cipto Mangunkusumo Hospital, Indonesia, from January 2017 - June 2017. Results: There were twenty one cases of post-cataract surgery endophthalmitis undergoes PPV within the period of January 2017-June 2017. The most frequently identified causative microorganism was Staphylococcus (23%). There was an improvement of visual acuity after PPV procedure in 47,6% post-cataract surgery endophthalmitis. Conclusion: Immediate PPV is an effective treatment and leads to vision improvement in post-cataract surgery endophthalmitis.   Keywords: pars plana vitrectomy, endophthalmitis, cataract surgery
