OBJECTIVE: The aim of this study is to compare subfoveal choroidal thickness (SFCT) before and after uneventful phacoemulsification using enhanced depth imaging optical coherence tomography (EDI-OCT). BACKGROUND: Cataract is a major cause of visual impairment in the elderly. Cataract surgery is the most common ophthalmic surgery and is performed simultaneously with glaucoma or vitreous surgery in many cases. However, according to the results in epidemiology studies, cataract surgery is associated with the onset of age-related macular degeneration (AMD) and cataract surgery increases visual acuity in these patients without an increased risk of progression to exudative AMD...

This study aimed to investigate the influence of silicone oil on the retinal nerve fiber layer (RNFL) thickness in patients with primary rhegmatogenous retinal detachment who underwent vitreoretinal surgery. The study included 47 patients (eyes), who underwent a pars plana vitrectomy with the silicone oil tamponade. The control group included unoperated eye of all participants. Spectral-domain optical coherence tomography (SD-OCT) was used for the measurements of peripapilar and macular RNFL thickness. The average peripapillary RNFL thickness was significantly higher in the silicone oil filled eyes during endotamponade and after its removal...

BACKGROUND: Central serous chorioretinopathy (CSC) is characterised by a serous detachment of the neurosensory retina in the macula. Chronic CSC tends to affect older individuals with a less favourable visual outcome. Photodynamic therapy (PDT) with verteporfin is a possible therapeutic approach in cases of CSC with no tendency for spontaneous resorption. PDT has shown good anatomic and functional results in treating chronic CSC. For the purpose of diminishing side effects, modifications of the standard protocol were used...

Despite recent advances in the medical management of diabetic retinal disease, there remain established indications for vitreoretinal surgery in the treatment of severe proliferative diabetic retinopathy. These include non-clearing vitreous hemorrhage and tractional retinal detachment. Advances in surgical instrumentation, technique, and experience have led to improved visual outcomes, as well as a corresponding decrease in the incidence of postoperative complications. However, the presence of systemic and ocular factors in diabetic patients increases the risk of adverse events compared to non-diabetic individuals...

Diplopia is a disappointing and, at times, unanticipated consequence of what might otherwise be considered anatomically successful strabismus surgery. In this study, we review the existing literature regarding diplopia after strabismus surgery in the context of the senior author's experience. We divide postoperative diplopia types into cases that occur in the setting of normal binocular vision (or "normal" suppression) vs. cases that are the consequence of rare or anomalous sensorial adaptations. We then discuss how to identify patients at greatest risk based on history and preoperative testing, and we offer strategies for managing these sometimes-challenging cases...

Scleral buckling has an important role in the repair of certain categories of rhegmatogenous retinal detachments. These include detachments in young phakic patients, detachments associated with dialysis, and also in conjuction with vitrectomy in patients who have sustained trauma or have developed proliferative vitreoretinopathy. However, it can be associated with significant postoperative complications. The most important ones are refractive change, intrusion or extrusion, infection, globe ischemia, and choroidal detachments, amongst others...

Uveitis is a leading causes of blindness worldwide, and the development of cataracts is common due to both the presence of intraocular inflammation and the most commonly employed treatment with corticosteroids. The management of these cataracts can be very challenging and often requires additional procedures that can compromise surgical results. The underlying disease affects a relatively young population at higher risk of complications. Preoperative control of inflammation/quiescent disease for at least three months is generally accepted as the minimum amount of time prior to surgical intervention...

There are a number of surgical options for treatment of idiopathic intracranial hypertension (IIH) when it is refractory to medical treatment and weight loss. Optic nerve sheath fenestration (ONSF) is one of these options. Use of this procedure varies among centers due to experience with the procedure and concern for associated complications that can result in severe loss of vision. This review summarizes the literature concerning post-surgical complications of ONSF for IIH.
