The brains of early-blind individuals appear to reorganize, thereby retaining tactile and auditory sensory response.

VANCOUVER, British Columbia — Patients with retinal vein occlusions appear to have significantly more comorbidities, as well as an increased risk for cerebrovascular accident.

Distinct phenotypic expression of Leber's hereditary optic neuropathy may signify that antituberculosis medications act as an epigenetic factor in the disease.

A 71-year-old man was referred to our practice for evaluation of a chronically red left eye for the past 3 months. There was no associated discharge or pain. He also initially noted blurry vision in the left eye while watching a football game 3 months ago. Since that point, he feels the blurry vision has progressively worsened. Two months prior to presentation, he developed binocular diplopia on upgaze, which has persisted. There was no history of trauma.

While 5% of eyes that received sub-Tenon injection of triamcinolone acetonide developed secondary ptosis, reconstructive surgery was successful, and satisfactory results were achieved after injection in all cases, a study found.

SAN FRANCISCO — After diagnosis and treatment of optic neuritis, patients often need follow-up that helps manage their mindset of the disorder, a speaker said here.

SAN FRANCISCO — Eye ache has benign, likely benign or not benign causes, and the reason for the ache should be determined to provide the most appropriate care, Mark L. Moster, MD, said.

A 70-year-old man initially presented to his ophthalmologist for several years of poor vision in both eyes, for which he was diagnosed with bilateral brunescent cataracts. The patient was scheduled for cataract surgery in his right eye but began noticing left eye swelling and redness 6 weeks before surgery and decreased vision in the left eye. The patient also began to note binocular diplopia around this time.

Leber's hereditary optic neuropathy can cause significant vision loss, perhaps worse compared with other ophthalmic disorders, and may be typified by rapid onset of vision loss and a poor long-term prognosis.

A 65-year-old Asian woman presented to the Tufts Medical Center emergency room with an acute, painful swollen left eye for approximately 15 hours and acute worsening over the past 4 hours.
