Occlusion for stimulus deprivation amblyopia.

Background: Stimulus deprivation amblyopia (SDA) develops due to an obstruction to the passage of light secondary to a condition such as cataract. The obstruction prevents formation of a clear image on the retina. SDA can be resistant to treatment, leading to poor visual prognosis.

Preserved Visual Acuity in Anterior Ischemic Optic Neuropathy Secondary to Giant Cell (temporal) Arteritis.

Objective: To evaluate the prevalence and clinical profile of patients with biopsy-proven arteritic anterior ischemic optic neuropathy presenting with preserved visual acuity of 20/40 or better and those with an initial poor visual acuity of 20/50 or worse through a retrospective chart review.

Results: Nine of 37 patients with arteritic anterior ischemic optic neuropathy presented with a preserved visual acuity of 20/40 or better in the affected eye. All patients with preserved visual acuity had initial visual field defects that spared the central field.

Strabismus surgery before versus after completion of amblyopia therapy in children.

Background: Normal visual development occurs when the brain is able to integrate the visual input from each of the two eyes to form a single three-dimensional image. The process of development of complete three-dimensional vision begins at birth and is almost complete by 24 months of age. The development of this binocular vision is hindered by any abnormality that prevents the brain from receiving a clear, similar image from each eye, due to decreased vision (e.

Medical treatment options for ocular myasthenia gravis.

Purpose Of Review: To update our current concepts of ocular myasthenia gravis medical management and to provide a short overview of upcoming treatments.

Recent Findings: Cholinesterase inhibitors and corticosteroids have been the first-line treatment for ocular myasthenia gravis. Several studies on other immunosuppressants, either as a steroid-sparer, steroid adjuvant or initial monotherapy, have demonstrated significant clinical efficacy.

Asaccadia and ataxia after repair of ascending aortic aneurysm.

Absent saccades is a rare complication of cardiovascular procedures. We present a patient who developed absent volitional saccades and reflex fast eye movements, low gain pursuit, and intact oculocephalic slow phases, dysphagia, dysarthria and progressive gait instability following repair of an ascending aortic aneurysm. Postulated pathophysiologies and prognosis for this syndrome are discussed.

Prevalence of a normal C-reactive protein with an elevated erythrocyte sedimentation rate in biopsy-proven giant cell arteritis.

Objective: The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are laboratory tests that have been said to have a strong correlation with a positive temporal artery biopsy in patients with suspected giant cell arteritis (GCA). Published reports suggest that the CRP is a more sensitive diagnostic indicator of GCA and can be elevated when the ESR is normal. It is also clear that the CRP and ESR can both be normal or both be elevated in patients with biopsy-proven GCA and that the CRP can be elevated when the ESR is normal.

Pharmacological testing of anisocoria.

Anisocoria, or a difference in pupil size, is a common condition. Its aetiology ranges from benign to life-threatening conditions. The clinical evaluation of anisocoria is discussed, emphasising the pharmacological aids (e.
