Bilateral Secondary Angle Closure During Daratumumab Infusion: A Case Report and Review of the Literature
We report a case of a patient with amyloidosis who developed bilateral, acute secondary angle closure during an infusion of daratumumab. Ultrasound biomicroscopy obtained 3 days after the onset of her symptoms demonstrated the cause to be bilateral choroidal effusions. Taken together with several previous case reports, the evidence suggests that, like topiramate, daratumumab is associated with the idiosyncratic reaction of choroidal effusions, resulting in a spectrum of clinical outcomes from myopic shift to acute angle closure. The treating oncologist and eye care provider should be aware of these adverse outcomes in any ...

Magnetic Resonance Imaging for Glaucoma Evaluation
The damage caused by glaucoma has been extensively evaluated at the level of the retina and optic nerve head. Many advances have been shown in this field in the last decades. Recent studies have also proved degenerative changes in the brain involving the intracranial optic nerve, lateral geniculate nucleus, and visual cortex. Moreover, these brain abnormalities are also correlated with clinical, optic nerve head, and visual field findings. In this review, we critically evaluate the existing literature studying the use of magnetic resonance imaging in glaucoma, and we discuss issues related to how magnetic resonance imaging...

Improving the Detection of Glaucoma and Its Progression: A Topographical Approach
Glaucoma is typically defined as a progressive optic neuropathy characterized by a specific (arcuate) pattern of visual field (VF) and anatomic changes. Therefore, we should be comparing arcuate patterns of damage seen on VFs with those seen on optical coherence tomography (OCT) maps. Instead, clinicians often use summary metrics such as VF pattern standard deviation, OCT retinal nerve fiber (RNF) global thickness, etc. There are 2 major impediments to topographically comparing patterns of damage on VF and OCT maps. First, until recently, it was not easy to make these comparisons with commercial reports. While recent repor...

“Pseudophakic Reverse Pupillary Block” Following Yamane Technique Scleral-fixated Intraocular Lens
Conclusions: The present case describes a rare complication of “pseudophakic reverse pupillary block” after a glued SFIOL implantation. The probable mechanism for the pupillary block is the reduced gap between the posterior surface of iris and optic of the IOL. This is likely caused by the loss of 5-degree posterior angulation of the 3-piece IOL because of stretching of the haptics leading to an increase in the iridolenticular contact and reverse pupillary block and elevated IOP. The persistent anterior chamber inflammation as a result of iris chaffing and pigment dispersion could also contribute to compromis...

A Case of Choroidal and Vitreous Hemorrhage Following Micropulse Transscleral Cyclophotocoagulation
We report a case of choroidal and vitreous hemorrhage after micropulse cyclophotocoagulation. An 82-year-old female presented postoperative day 1 with blurry vision and pain in her right eye. Examination showed that she had a choroidal hemorrhage, 200 degrees of ciliary body swelling, and vitreous hemorrhage. Although the choroidal hemorrhage resolved with steroids, the vitreous hemorrhage required pars plana vitrectomy. To the best of our knowledge, this article discusses the first reported case of choroidal and vitreous hemorrhage due to micropulse cyclophotocoagulation. (Source: Journal of Glaucoma)

Reticular Corneal Edema or Corneal Honeycombing in Eyes Treated With Netarsudil: A Case Series
This is a descriptive case series of 3 patients with uncontrolled intraocular pressure that developed reticular corneal changes after initiating netarsudil (0.02%). In all cases, upon observing reticular corneal edema, netarsudil (0.02%) was stopped followed by disappearance of corneal honeycombing. With the increasing use of this novel glaucoma medication, potentially more rare side effects will be observed. Reticular corneal edema or corneal honeycombing is an ocular examination finding that can rarely occur after initiating netarsudil (0.02%) regardless of prior corneal edema status. In our experience, the reticular cha...

Repair of Tube Erosion by Modifying the Tube Extender
We describe here a case report of a novel technique for tube erosion repair, which modifies and utilizes the commercially available tube extender (Model TE).

Do Levels of Stress Markers Influence the Retinal Nerve Fiber Layer Thickness in Young Adults?
Precis: Although mental or emotional stress may result raise in intraocular pressure (IOP) we found weak associations between endogenous stress markers concentrations and retinal nerve fiber layer (RNFL) thickness, thus limited evidence that stress affects retinal ganglion cells integrity. Purpose: Increased exposure to glucocorticoids is linked to elevated IOP, which is a risk factor for glaucoma. We explored the RNFL thickness for changes that may mimic preclinical glaucomatous changes, in relation to the hormonal stress response. Materials and Methods: Young healthy adults (n=863) underwent a Trier Social Stress...
