Nonconforming Deep Focal Choroidal Excavation in a Patient With Choroidal Osteoma: A Diagnostic Dilemma
Choroidal osteoma (CO) is a benign ossifying tumor commonly occurring in young females.1 Due to its peripapillary/macular location, vision inevitably gets affected during the course of tumor evolution.2 The fate of CO may be variable. It can undergo decalcification leading to loss of overlying choriocapillaries with atrophy of the outer retina, or it may lead to chronic retinal pigment epithelium (RPE) decompensation leading to a persistent neurosensory detachment (NSD).3 The most common cause of vision loss is due to choroidal neovascularization (CNV).3 Also, as these findings may coexist (Source: Ophthalmic Surgery, Lase...

Pain Associated With a Subconjunctival Cefazolin-Lidocaine Mixture in Retinal Surgery:A Randomized Control Trial
Endophthalmitis is a sight-threatening eye infection that can complicate any type of intraocular surgery including vitreoretinal surgery. The incidence, risk factors, management, microbiology, and prognosis of endophthalmitis following vitreoretinal surgery have been well-described, which demonstrated that this complication is rare but has a poor prognosis.1,2It is a common practice to administer either a subconjunctival or intracameral antibiotic at the end of cataract surgery to reduce the risk of postoperative endophthalmitis.3 In vitreoretinal surgery, the anterior segment is often not (Source: Ophthalmic Surgery, Lase...

Treatment of Ipilimumab-Induced Vogt-Koyanagi-Harada Syndrome With Oral Dexamethasone
Ipilimumab (Yervoy; Bristol-Myers Squibb, New York City, NY) is a human monoclonal antibody to cytotoxic T-lymphocyte antigen 4 (CTLA-4) and has been shown to increase median survival in patients with unresectable metastatic melanoma1 and stage 3 melanoma after surgical resection.2 The U.S. Food and Drug Administration (FDA) approved ipilimumab for the treatment of unresectable or metastatic melanoma in 2011. By inhibiting CTLA-4, which is an innate inhibitor of T-cell costimulation, ipilimumab is able to potentiate the host's immune system and promote T-cell proliferation against malignant (Source: Ophthalmic Surgery, Las...

DualTrack Technology Improves Optical Coherence Tomography Angiography Image Quality
Optical coherence tomography angiography (OCTA) allows visualization of ocular vessels by detecting motion contrast from flowing blood. Motion contrast can be detected by two different validated methods: the “speckle decorrelation,” which detects intensity changes in OCT structural image, and the “phase variance,” which assesses changes in the phase of light wave.1–7OCT samples a discrete tissue volume and generates a numerical value based on the reflectivity of the volume. This numerical value corresponds to a voxel (that is a portmanteau of “volume” and “pixel”) in the image displayed. Each (Source: Oph...

Valved 25-Gauge Cannula for Vitreous Tap and Injection
When infectious endophthalmitis is suspected, a vitreous tap and intravitreal injection of antibiotics are often employed to obtain a specimen for diagnosis and administer treatment. This in-office procedure normally consists of introducing a short 25- or 27-gauge needle on a 5-mL or 10-mL syringe 3 mm to 4 mm posterior to the limbus of an anesthetized eye using standard sterile technique.1 Gentle suction is manually applied to withdraw a vitreous sample to be sent to the laboratory for microbiologic analysis. Next, multiple intravitreal injections of antibiotics and/or steroid are (Source: Ophthalmic Surgery, Lasers and I...

Comparison of Pneumatic Retinopexy and Scleral Buckle for Primary Rhegmatogenous Retinal Detachment Repair
The scleral buckle procedure (SBP) was pioneered by Charles Schepens in 1957 and revolutionized the treatment of patients with retinal detachment.1 In comparison to the 30% to 40% success rates initially reported by Gonin,2 scleral buckling has been reported to result in anatomic reattachment in up to 94% of uncomplicated retinal detachment cases.3 The surgery also offers significant longevity, with anatomic success lasting 20 years or more in the large majority of cases.4Pneumatic retinopexy (PR) was introduced by Hilton and Grizzard in 1986. PR allows surgeons to potentially avoid some of (Source: Ophthalmic Surgery, Las...

Single-Spot Yellow Laser Versus Conventional Green Laser on Panretinal Photocoagulation: Patient Pain Scores and Preferences
Proliferative diabetic retinopathy remains a leading cause of visual impairment in economically active populations in developing, as well as developed, countries. It results in 12,000 to 24,000 new cases of blindness each year in the United States.1,2 Diabetic visual impairment might be prevented by two main strategies: early diabetic retinopathy diagnosis and panretinal photocoagulation (PRP) therapy.1 Many multinational trials have shown the benefits of PRP in high-risk proliferative diabetic retinopathy (PDR), where a reduction of severe visual loss in up to 60% of cases has been (Source: Ophthalmic Surgery, Lasers and ...

Navigating the Options for the Treatment of Intraocular Lens Malposition
Howard F. Fine, Practical Retina Co-EditorThere has been a wave of new and innovative techniques for vitreoretinal surgeons in the management of aphakia as well as subluxed or dislocated intraocular lenses (IOLs). Several of these techniques are quite elegant and fun to perform, but most incur a learning curve to master. Having a number of these options available is crucial to maximizing patient outcomes when presented with varying clinical scenarios.Our anterior segment colleagues are often extremely grateful for our assistance with these cases, for example when rescuing a “premium IOL” (Source: Ophthalmic Surgery, La...

Irvine-Gass Macular Edema Responding to the Combination of Oral Mineralocorticoid-Receptor Antagonist With Dexamethasone Drops
Postoperative macular edema (ME), also termed pseudophakic ME or “Irvine-Gass syndrome,”1,2 is a vision-limiting complication occurring after intraocular surgery. Its frequency is estimated at 1.2% after routine cataract extraction3 and is probably higher following complex anterior or posterior segment procedures. Diabetes, lens capsule rupture, history of ep iretinal membrane, uveitis, retinal vein occlusion, or retinal detachment are known risk factors.3 On average, affected eyes harbor worse postoperative visual acuity (VA).3,4 Several treatments have been used, including oral (Source: Ophthalmic Surgery, Lasers and...

Changes in Subfoveal Choroidal Thickness During Pregnancy and After Delivery
Since Spaide et al.1 reported that clear choroidal images could be obtained using enhanced depth imaging optical coherence tomography (EDI-OCT), changes in the choroidal thickness in association with various ocular pathologies such as central serous chorioretinopathy,2,3 age-related macular degeneration,4 polypoidal choroidal vasculopathy,5 and Vogt-Koyanagi-Harada disease6,7 have been investigated. With such research, the pathophysiology of the choroid in these diseases has been elucidated. In the healthy individual, the choroidal thickness shows negative correlations with both age and axial (Source: Ophthalmic Surgery, L...

Characterization of Artifacts Associated With Multicolor Confocal Scanning Laser Ophthalmoscopy
Multicolor confocal scanning laser ophthalmoscopy (cSLO) is a novel imaging modality on a commercially available optical coherence tomography (OCT) system (Spectralis; Heidelberg Engineering, Heidelberg, Germany) that utilizes three discrete lasers to simultaneously capture data from various structures of the ocular fundus. Infrared (IR) reflectance has the potential to visualize retinal pigment epithelium (RPE), drusen, and choroidal abnormalities. Green reflectance highlights hemorrhages and retinal vasculature, whereas blue reflectance produces detailed images of surface retinal pathology (Source: Ophthalmic Surgery, La...
