Considerations for the Identification and Management of Geographic Atrophy: Recommendations from an Expert Panel.

Newly approved treatments for patients with geographic atrophy are changing the treatment paradigm, highlighting the need for eye care providers (ECPs) to have a set of recommendations on how to best manage GA patients. Here, we outline how to identify various stages of age-related macular degeneration including geographic atrophy (GA) by examining optimal management scenarios implicating various ECPs and reviewing treatment considerations for patients with GA. Early identification of GA will lead to optimal patient outcomes, while a standardized management scenario will reduce clinical burden among ECPs treating patients with GA.

Methods: A modified Delphi panel process (Geographic Atrophy Management Consensus) consisting of three total surveys and one virtual live meeting held between survey 2 and survey 3. Data were collected from July to October 2022.

Clinical-grade stem cell-derived retinal pigment epithelium patch rescues retinal degeneration in rodents and pigs.

Considerable progress has been made in testing stem cell-derived retinal pigment epithelium (RPE) as a potential therapy for age-related macular degeneration (AMD). However, the recent reports of oncogenic mutations in induced pluripotent stem cells (iPSCs) underlie the need for robust manufacturing and functional validation of clinical-grade iPSC-derived RPE before transplantation. Here, we developed oncogenic mutation-free clinical-grade iPSCs from three AMD patients and differentiated them into clinical-grade iPSC-RPE patches on biodegradable scaffolds.

Ocular histoplasmosis syndrome.

Ocular histoplasmosis syndrome (OHS) is a chorioretinal disorder with a distinct fundus appearance that is commonly found in regions endemic for Histoplasma capsulatum. Choroidal neovascularization (CNV) secondary to OHS is considered one of the principal causes of central vision loss among young adults in endemic areas. Although there is no consensus regarding its pathogenesis, evidence points to Histoplasma capsulatum as the most probable etiology.

Microcysts in the inner nuclear layer, a nonspecific SD-OCT sign of cystoid macular edema.

Recently, many authors have propagated the notion that a specific form of "microcystic macular edema" occurs in patients with optic neuritis and optic atrophy of various etiology and is due to retrograde synaptic degeneration. The finding is isolated to the inner nuclear layer on spectral-domain optical coherence tomography in most cases, and is present in a parafoveal, circumferential, and central macular distribution. This perspective critically reviews the evidence and suggests that inner nuclear layer cystoid changes are an early and nonspecific indicator of typical cystoid macular edema of any cause, and that the finding is likely not a distinct entity.
