Acute vision loss in intracranial hypertension secondary to choroidal neovascularization

We observed a rare ocular complication of choroidal neovascularisation (CNV) in a patient with idiopathic intracranial hypertension (IIH). The mechanism and treatment of such cases remain controversial

Nonmydriatic ocular fundus photography among patients with focal neurologic deficits in an emergency department (ED)

While several large cohort studies have associated ocular fundus abnormalities with the long-term risk of stroke, the value of ocular fundus examination in patients presenting with focal neurologic deficits, particularly suspected transient ischemic attack (TIA) and stroke, has not been evaluated. The ABCD2 score is widely used for the risk stratification of patients with suspected TIA, but does not include fundus findings. Our objective was to determine the frequency of and the predictive factors for abnormal ocular fundus findings among ED patients who presented with focal neurologic deficits

Asymmetric Papilledema with Surprising Outcomes

The diagnosis of pseudotumor cerebri (PTC) can be straight forward when there is bilateral optic disc edema and when the symptoms, signs, and work-up match the modified Dandy-Walker criteria. However, in atypical patient presentations with asymmetric disc edema, there are diagnostic and treatment decision dilemmas

An Atypical Presentation of Giant Cell Arteritis

We observed an atypical presentation of giant cell arteritis that initially made the diagnosis difficult

INTACT RETINAL TISSUE AND RETINAL PIGMENT EPITHELIUM IDENTIFIED WITHIN A COLOBOMA BY HIGH-SPEED, ULTRAHIGH-RESOLUTION OPTICAL COHERENCE TOMOGRAPHY

Purpose—To report on a posterior segment coloboma manifesting unusual morphology as determined by high-speed, ultrahigh resolution optical coherence tomography imaging (hsUHROCT). Methods—A 47-year-old patient with bilateral colobomas was evaluated via fundus examination and hsUHR-OCT. Results—Imaging with hsUHR-OCT showed intact retinal pigment epithelium (RPE) within the posterior segment coloboma. Most of the retinal layers appeared to continue into the coloboma, although they exhibited slight attenuation. The external limiting membrane (ELM) was clearly visible continuing within the coloboma, suggesting that Muller cells and the inner segments of the photoreceptors were still present in this area. The junction between the inner and outer segments of the photoreceptors ended at the margin of the coloboma, which may be due to either photoreceptor disruption or a change in the orientation of the outer segments. Conclusion—hsUHR-OCT demonstrated the presence of Muller cells and photoreceptor inner segments within a posterior segment coloboma. The retinal pigment epithelium (RPE) was intact within the coloboma, representing an unusual morphology.National Institutes of Health (U.S.) (Grant R01-EY11289-21)United States.
