This is a case of Valsalva retinopathy during the season of annual transboundary haze pollution in Sarawak. A 22-year-old man with no known medical illness developed sudden onset of painless visual acuity loss preceded by persistent cough. Left eye fundus showed dense preretinal haemorrhage covering optic disc extendinginferiorly with breakthrough vitreous haemorrhage. The patient underwent pars plana vitrectomy, endolaser, and fluid gas exchange in view of persistent dense vitreous haemorrhage after a month of conservative management. In conclusion, pars plana vitrectomy can be considered as a safe and effective treatment option for patients with Valsalva retinopathy developing extensive premacular haemorrhage.

Acute Event

Purpose To report some interesting findings in patients with bilateral Terson syndrome. Methods We describe six eyes from three patients with Terson syndrome. Pars plana vitrectomy was performed in one eye twelve weeks, and in four eyes six months after the acute event. In one eye blood was suddenly spontaneously absorbed after four months. Results The four eyes operated six months after injury showed severe complications and final visual acuity was between light perception and 0.6. The eye with surgical attendance twelve weeks after the acute injury had an uneventful course, and final visual acuity was 0.7. Conclusions Because of severe ocular complications and with a view to early rehabilitation, vitrectomy has been recommended for eyes with bilateral Terson syndrome, without spontaneous blood resorption. Surgery should be performed in at least one eye not later than four to eight weeks after the acute injury.

Purpose. To evaluate the outcome and identify the prognostic factors of traumatic endophthalmitis over a 5-year period.Methods. We reviewed the medical records of all the traumatic endophthalmities that we treated in our department over the last 5 years (2009–2013). We extracted the following parameters: age, gender, wound anatomy, associated ocular lesions, treatment, and initial and final visual acuities. We used the program SPSS version 20.0.0. for the statistical analysis of our data.Results. During the last 5 years, we treated 14 traumatic endophthalmities, representing 46.66% of all types of endophthalmities. The infection rate in open globe injuries was 8.13% and 34.78%, if an intraocular foreign body (IOFB) was associated. All the patients were males with the median age of 37 years. Initial visual acuities varied between light perception and 0.4 and the timing of treatment from a few hours to 10 days. We administered antibiotic and anti-inflammatory drugs, systemically and intravitreally, in all cases. We performed pars plana vitrectomy in 64.28% of cases. In 57.14% of cases, the final visual acuity was 0.1 or more.Conclusions. IOFBs increased significantly the risk for endophthalmitis. The worse prognostic factors were retinal detachment at presentation and delayed treatment. This trial is registered withIRCT2014082918966N1.

Plaque Brachytherapy

A 47-year-old man presented with profound loss of vision in right eye and relative afferent pupillary defect. On fundus examination, posterior pole details were obscured due to dense vitreous haemorrhage. B-scan ultrasonography was performed that revealed a mushroom-shaped hyperechoic lesion with medium internal reflectivity on A-scan ultrasonography. After performing contrast-enhanced MRI of the orbit, a diagnosis of choroidal melanoma was established. Patient was managed using plaque brachytherapy based on multiplanar MRI. This was followed 10 months later by pars plana vitrectomy and cataract extraction. Vision postoperatively improved to 20/60. A systematic clinical assessment along with supportive ancillary investigations augments diagnostic accuracy and reduces delay in definitive management.

Pars Plana

Pars plana vitrectomy (PPV) with silicone oil implantation (SOI) was performed for advanced proliferative diabetic retinopathy (PDR) in 110 eyes of 98 diabetic patients. In, 77 eyes (70%) it was a primary SOI as part of the initial operation; in 33 eyes (30%) it was a secondary SOI in reoperations. Indications for SOI were traction retinal detachment of the posterior pole, combined traction and rhegmatogenous detachment, vitreous haemorrhage with florid vascularised fibrous proliferations, and recurrent vitreous haemorrhage after PPV. The patients were followed up for 24 to 72 months, with a mean of 53 months. At the end of follow-up, anatomical success was achieved in 63 eyes (57%), and functional success with visual acuity 0.01 and better in 35 eyes (32%). Functional failures were caused by retinal redetachment in 47 eyes (43%), by secondary glaucoma in 10 eyes (9%), retinal ischemia in 15 eyes (13%) and keratopathy in three eyes (3%). The functional success rate decreased with follow-up from 67% after six months to 50% by 60 months after SOI. Silicone oil bubble in the anterior chamber, rubeosis iridis, cataract, and glaucoma were the most frequent postoperative complications. PPV with SOI was highly effective in many serious complications of advanced PDR. Functional success was mostly lasting and markedly improved the quality of life of these patients.

The Endophthalmitis Vitrectomy Study (EVS) was a randomized, controlled clinical trial to determine the roles of immediate pars plana vitrectomy and systemic antibiotic treatment in the management of postoperative endophthalmitis in patients with clinical signs and symptoms of bacterial endophthalmitis within 6 weeks of cataract surgery or secondary intraocular lens (IOL) implantation and visual acuity between 20/50 and light perception. The study found that routine immediate pars plana vitrectomy is not necessary in patients with better than light perception vision at presentation but is of substantial benefit for those who have light perception-only vision (or worse). Most patients do not require treatment with intravenous antibiotics. Omission of systemic antibiotic treatment can reduce toxic effects, costs, and length of hospital stay.

Purpose. To evaluate the effectiveness and safety of perfluorohexyloctane (F6H8) for intraoperative flattening of the retina and of F6H8/silicone oil (SO) 1000 cSt as a postoperative tamponade for inferior retinal detachment with inferior proliferative vitreoretinopathy.Methods. This is a retrospective review of 22 patients who underwent pars plana vitrectomy using F6H8 as an intraoperative tool to flatten the retina. At the end of the surgery a direct partial exchange between F6H8 and SO 1000 cSt was performed, tamponing the eye with different ratios of F6H8/SO (70/30, 60/40, 50/50, 40/30, and 30/70). Anatomical and functional results and complications were evaluated over the follow-up period (mean 22.63 months).Results. F6H8 was efficacious for intraoperative flattening of the retina. Twenty-one of the 22 patients achieved a complete retinal reattachment. Postoperative visual acuity (VA) ranged from light perception to 20/70, with 72% of patients obtaining VA better than 20/400. No emulsification/inflammation was observed whatever the ratio of F6H8/SO used. With higher ratios of F6H8/SO (70/30 and 60/40) cloudiness of the tamponade was observed. A transparent mixture was present with all the other ratios.Conclusions. The surgical technique adopted is very simple and safe. The optimal F6H8/SO ratio seems to be between 50/50 and 30/70.

Back ground: Trans-pars plana vitrectomy (TPPV) is an effective surgical procedure to retain the useful vision in vitreoretinal diseases. Objective: To evaluate the surgical outcome of pars plana vitreoretinal surgery. Study design: Retrospective non-comparative interventional case series. Materials and methods: A hospital-based retrospective interventional study of series of cases was carried out in retina clinic of Lumbini Eye Institute, Nepal, over a period of one-and-a-half years. Records of 64 patients who underwent vitreo-retina surgeries were reviewed. Demography, duration of symptoms, risk factors and indications, preoperative and post-operative visual acuity, intra-operative and post-operative complications were analyzed. Outcome measurement: The parameters studied were post-operative visual acuity and complications. Results: Of 64 patients, 61 % presented 2 months after the onset of symptoms. Preoperatively, 65.5 % had visual acuity of hand motions to 3/60 followed by perception of light only in 26.6 %.The main indication for TPPV was vitreous haemorrhage (VH), in 53 %. The visual acuity improved to better than 6/60 in patients with VH (68 %), whereas, overall, in 72 % of the subjects, it improved by 2 lines postoperatively. The commonest intra-operative complications were iatrogenic retinal break (5, 7.8%) at the sclerostomy site. Conclusion: The main indication for TPPV is vitreous haemorrhage. Useful vision can be restored by pars plana vitrectomy in the majority of the patients. Retinal break is the commonest complication of TPPV.
