OBJECTIVE The use of Gamma Knife radiosurgery (GKRS) as monotherapy in the treatment of uveal melanoma (UM) allows clinicians to achieve high local tumor control with low recurrence but does not prevent secondary enucleation due to glaucoma in cases of large tumors. The authors analyzed indications for tumor endoresection (ER), the time interval between irradiation and surgery, and the features and results of performing ER for UM after GKRS. METHODS Thirty-seven patients between 28 and 78 years of age (16 male and 11 female patients) with UM underwent GKRS with a dose of 70 to 80 Gy that was applied to the center of the tumor with complete immobilization of the eye during the procedure...

Introduction. Terson syndrome is described as intraocular hemorrhage in association with any type of intracranial hemorrhage and is associated with higher mortality rate and vision loss. Intraocular hemorrhage in Terson syndrome may be diagnosed using computed tomography but there are false positive results. Silicone oil which is widely used for internal tamponade of complicated retinal detachments has high attenuation on computed tomography and hyperintensity on T1-weighted magnetic resonance imaging that can mimic intraocular hemorrhage...

Diabetic retinopathy (DR) is the most frequent microvascular complication from diabetes and requires annual screening and at least annual follow-up. A systemic approach to optimize blood glucose and blood pressure may halt progression to severe stages of DR and obviate the need for ocular treatment. Although there is evidence of benefit from fenofibrate or intravitreous antiVEGF treatment for eyes with nonproliferative DR (NPDR), these therapies are not standard care for NPDR at this time. Some patients with severe NPDR, especially those with type 2 diabetes, benefit from early panretinal photocoagulation (PRP)...

The authors describe a technique to qualitatively analyze the posterior segment during cataract surgery using intraoperative optical coherence tomography (iOCT). Macular iOCT can be done before and after intraocular lens implantation after the media is rendered clear following phacoemulsification. A handheld irrigating planoconcave contact lens is placed over the cornea with the operating microscope in retroillumination mode. After focusing the microscope and upon getting a clear view of the posterior segment, iOCT is switched on, centered at the macula, and focused...

New modalities for the treatment of diabetic eye complications have emerged in the past decade. Nevertheless, many severe diabetic retinopathy complications can only be treated with vitreoretinal surgery. Technological advances in pars plana vitrectomy have expanded the gamut of pathologies that can be successfully treated with surgery. The most common pathologies managed surgically include vitreous opacities and traction retinal detachment. The indications, surgical objectives, adjunctive pharmacotherapy, microincisional surgical techniques, and outcomes of diabetic vitrectomy for proliferative diabetic retinopathy and diabetic tractional retinal detachment will be discussed...

BACKGROUND: It is unclear whether or not an additional encircling band improves outcome in vitrectomy for pseudophakic retinal detachment (PRD). Also unclear is whether small gauge transconjunctival trocar-guided vitrectomy is as successful as conventional 20 gauge (G) vitrectomy. METHODS: 257 adult patients with uncomplicated PRD were enrolled in 14 vitreoretinal centres across Germany. Contingent on availability of qualified surgeons, eligible patients were randomly assigned either (i) with ratio 1:1 to 20 G vitrectomy plus encircling band (group E1) or 20 G vitrectomy without any buckle (group C) or (ii) with ratios 1:1:1 to group E1, C or 23/25 G vitrectomy without any buckle (group E2)...
