Meta AnalysisComparison between Ozurdex and intravitreal anti-vascular endothelial growth factor treatment for retinal vein occlusion-related macular edema: A systematic review and meta-analysis of randomized controlled trials.
This systematic review aimed to evaluate the effectiveness and safety of intravitreal dexamethasone (DEX) implant and intravitreal anti-vascular endothelial growth factor (VEGF) treatments for macular edema (ME) secondary to retinal vein occlusion (RVO), central retinal vein occlusion (CRVO), and branch retinal vein occlusion (BRVO). The electronic databases comprehensively searched for the studies that compared DEX with anti-VEGF treatments in patients suffering from RVO-related ME. The effectiveness was estimated using best-corrected visual acuity (BCVA), central retinal thickness (CRT), and intraocular pressure (IOP). ⋯ Anti-VEGF agents were also effective treatments for cataract formation or less adverse events for RVO-related ME. In contrast, DEX implant had higher risk for IOP elevation and lower cataract incidence than anti-VEGF agents. Hence, complementary and alternative treatments are expected.

To track citation patterns in ophthalmic journals and contrast them with major medical and surgical journals from 1997 to 2009. In addition, we want to familiarize the ophthalmic community with bibliometrics indices. ⋯ JIF tends to rise annually by 10% in medical, surgical, and ophthalmic fields. Journals publishing reviews, basic science, or large volume on broad range of topics rank at the top for JIF. The rapid rise of JIF for Retina unlike other subspecialties that stayed status quo is multifactorial: Change in editorial policies (introduction of review articles and omission of case reports) and technological advances in the retinal field.

Review Case ReportsPerioperative visual loss with non-ocular surgery: case report and review of literature.
Perioperative visual loss (POVL), a rare but devastating complication, has been reported after spine, cardiac, and head-neck surgeries. The various causes include ischemic optic neuropathy, central or branch retinal artery occlusion, and cortical blindness. The contributory factors described are microvascular diseases and intraoperative hemodynamic compromise. ⋯ A case of POVL with caesarian section surgery is being presented. The visual loss occurred due to a combined occlusion of central retinal artery and vein. The causes, presentation, and risk factors of POVL after non-ocular surgery are being discussed.

Acute corneal hydrops is a condition characterized by stromal edema due to leakage of aqueous through a tear in descemet membrane. The patient presents with sudden onset decrease in vision, photophobia, and pain. Corneal thinning and ectasias combined with trivial trauma to the eye mostly by eye rubbing is considered as the underlying cause. ⋯ Intracameral injection of air or gas such as perflouropropane is the most common surgical procedure done. Recent investigative modality such as anterior segment optical coherence tomography is an extremely useful tool for diagnosis, surgical planning, and postoperative follow up. Resolution of hydrops may improve the contact lens tolerance and visual acuity but most cases require keratoplasty for visual rehabilitation.

Magnetic resonance imaging (MRI) and computerized tomography (CT) have added a new dimension in the diagnosis and management of ocular and orbital diseases. Although CT is more widely used, MRI is the modality of choice in select conditions and can be complimentary to CT in certain situations. ⋯ Ophthalmologists should be able to interpret these complex imaging modalities as better clinical correlation is then possible. In this article, we attempt to describe the basic principles of MRI and its interpretation, avoiding confusing technical terms.
