Does supplementation matter?...

A study published in Ophthalmology has found promising results in the management of a particular subtype of age-related macular degeneration (AMD). Oral antioxidant and lutein/zeaxanthin supplements, specifically the AREDS2 formulation, have demonstrated significant efficacy in slowing the progression of geographic atrophy (GA) to the fovea.

The research, conducted over an extended period, showed a marked reduction in progression rates among participants receiving supplementation. Notably, the fovea exhibited enhanced protection against GA advancement, potentially preserving visual function. The study's duration allowed for a comprehensive assessment of long-term supplement effectiveness, providing strong evidence for addition into our GA management protocols.

These findings are a reminder for us to consider incorporating these supplements into treatment strategies, offering our patients a non-invasive approach to help mitigate vision loss associated with GA progression.

Herpes Simplex Keratitis

Do You Know The Trigger?... Recents findings studying herpes simplex virus type-1 (HSV-1) keratitis may give us greater insight when we manage these individuals in daily practice. At least in this study (porcine), it appears HSV-1 infectious keratitis is primarily restricted to the corneal epithelium and likely triggered via epithelial defects or abrasion - not penetrating basement membran...

Nystagmus In Daily Practice

Do You Know Where To Start?... Whether congenital or acquired, nystagmus can be a difficult to understand and often mysterious complex ocular movement disorder. It is characterized by involuntary rhythmic eye movements, negatively impacting visual function and therefore quality of life. In daily practice, our approach to uncover an etiologic source often involves a combination of high-reso...

Implantable IOP Sensors vs Tonometry

Will This Change How You Manage Glaucoma?... Intraocular pressure (IOP) is usually our primary concern in managing glaucoma - assuming we also understand and always consider additional pathophysiologic dynamics in glaucomatous optic neuropathy. For example, factors involved in glaucomatous progression despite "target IOP" and/or with Normal Tension Glaucoma (NTG). However, also knowing IOP is...
