Incidental Finding of Suprachoroidal Space's Silicone Oil Migration: A Tumor-Mimicking Lesion and Its Clinical Management.

The migration of silicone oil into the suprachoroidal region is a rare complication of vitrectomy. A 70-year-old man was admitted to our ocular oncology unit with a choroidal elevation in the nasal area, as well as signs of pars plana vitrectomy surgery performed about 5 years ago for retinal detachment. The patient underwent ocular ultrasound, visual field test, fluorangiography, and magnetic resonance imaging, which led to the diagnosis of silicone oil migration in the suprachoroidal space. Silicone oil may move into the suprachoroidal area, mimicking choroidal neoformation. It is important to have a comprehensive diagnosis and then set up the appropriate treatment.

BILATERAL UVEITIS AND HYPOTONY FOLLOWING TREATMENT WITH TOPICAL CIDOFOVIR.

PURPOSE: To report a case of bilateral uveitis and hypotony associated with topical cidofovir treatment. METHODS: Case report. RESULTS: A 59-year-old diabetic man with HIV/AIDS presented with photophobia, ocular pain, and decreased vision. He was found to have bilateral hypotony, anterior uveitis, and serous choroidal detachments. Infectious disease workup, patient-reported history, and review of the patient's electronic medication list did not identify the etiology. Treatment with intensive topical corticosteroids led to resolution of uveitis and choroidal effusions within 3 months and resolution of hypotony within 9 months. Two years after his initial presentation, the patient developed acute recurrence of bilateral hypotony, anterior uveitis, and serous choroidal detachments shortly after intravenous cidofovir treatment. Careful reevaluation of the patient's outside medical records revealed that he had initiated treatment for rectal herpes simplex virus with compounded topical cidofovir one month before his initial presentation. CONCLUSION: To our knowledge, this is the first reported case of topical cidofovir causing ocular toxicity. Compounded and topical medications, like cidofovir in this case, may not appear on a patient's electronic medication list, so a focused review of outside medical records may be beneficial when a particular medication toxicity is suspected.

A Retrospective Case Series of Uveal Effusion Syndrome.

PURPOSE: This study aimed to describe the clinical findings and management of eyes affected by uveal effusion syndrome. METHODS: We retrospectively evaluated the charts of 13 eyes of 8 consecutive patients diagnosed with uveal effusion syndrome attending the Ophthalmology Unit of the University Hospitals Leuven, Belgium, between 2007 and 2018. The presenting features, investigations, management, and outcomes were analyzed for each case. RESULTS: Cataract surgery was the predisposing factor for uveal effusion in 6 eyes, 2 bilateral uveal effusions (4 eyes) were considered to be medication-induced, and in 3 eyes, the uveal effusion was described as idiopathic. Fundus examination of 5 of 13 eyes showed bullous choroidal detachment, treated with pars plana vitrectomy with superotemporal sclerectomy or transscleral punction. Fundoscopy showed uveal effusion without serous retinal detachment in 3 eyes. Serous retinal detachment accompanied by uveal swelling was observed in 3 eyes and the 2 remaining eyes presented with uveal swelling only. The 8 nonbullous choroidal detachments were treated in a conservative way. A rapid resolution of subretinal fluid and uveal effusion was observed in all cases. CONCLUSIONS: A conservative approach with acetazolamide treatment or just observation was used in our case series in choroidal detachment without substantial visual loss if, over time, slow improvement was documented. However, further studies are needed to verify the effectiveness of the reported therapy.

Contribution of the Visante® OCT and B-scan ultrasound in the diagnosis and follow up of a topiramate-induced bilateral ciliochoroidal effusion syndrome. / Aportes de la tomografía de coherencia óptica Visante® y la ecografía ocular en el diagnóstico y seguimiento del síndrome de efusión ciliocoroideo bilateral secundario a topiramato.

A 45 year-old man with bilateral acute angle-closure and myopia after starting treatment with topiramate, secondary to alcohol and heroin dependence. Using Visante® OCT (Optical Coherence Tomography) and B-scan Ultrasound he was diagnosed with bilateral ciliochoroidal effusion as the pathophysiological mechanism. Topiramate was stopped and ocular hypotensive therapy with a topical cycloplegic and corticosteroids were started, resolving ciliochoroidal effusion syndrome. Visante® OCT and B-scan Ultrasound are useful tools for the diagnosis and follow-up of patients with acute angle-closure and myopia due to topiramate. As a result of broad spectrum of indications for topiramate, physicians and ophthalmologists should be aware of the possible ophthalmological manifestations attributable to this drug.

Systemic Approach to Prevent Inadvertent Perfusion in Eyes with Extensive Choroidal Detachment, Suprachoroidal Fluid, and Hypotony During Pars Plana Vitrectomy.

INTRODUCTION: Rhegmatogenous retinal detachment (RRD) with extensive choroidal detachment (CD), suprachoroidal fluid (SCF), and lower intraocular pressure (IOP) markedly increase the difficulty of pars plana vitrectomy (PPV) because it makes the insertion and placement of the trocar cannulas for PPV time-consuming and technically challenging. In this study, we developed a systemic approach that avoids the risks of sclerotomy or using a longer trocar to help in the safe placement of the trocar cannulas in order to prevent inadvertent fluid/air perfusion during PPV in RRD eyes with extensive CD, SCF, and hypotony. METHODS: This is a prospective case series study. Consecutive patients diagnosed with RRD with extensive CD, SCF, and hypotony were recruited. The main steps included injecting transconjunctival intravitreal fluid to increase IOP and enable the passive egress of SCF into the subconjunctival space, creating and broadening the inner opening for the trocar cannulas, transillumination with an endoillumination light pipe, and indentation of the infusion cannula to create maximum visual exposure of the inner segment and help peripheral shaving around the infusion tip. MAIN OUTCOMES: the success rate of the infusion placement into the vitreous cavity, surgical duration, intra- and postoperative complications, and functional and anatomical outcomes. RESULTS: Thirty-eight patients (38 eyes) were included. The first-time success rate of cannula placement into the vitreous cavity was 100%, with a mean surgical duration of 8.5 ± 1.8 min. No intra- or postoperative complications related to the approach were observed. Significant vision improvement was noted in 68.4% (26/38) of the patients at the final follow-up. The primary and final retinal reattachment rates were 94.7% (36/38) and 100% (38/38), respectively. CONCLUSION: This systemic approach is a feasible option to ensure the safe placement of trocar cannulas and prevent inadvertent perfusion during small-gauge PPV in RRD eyes with extensive CD, SCF, and hypotony, without the need for a draining sclerotomy, a longer trocar, or a sharp clearing of the cannula tip.
