The 2025 Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting will take place May 4-8, 2025, in Salt Lake City, Utah. Ahead of this exciting meeting, several companies have announced that data from clinical trials will be shared at this event.

As researchers prepare for their presentations, we are highlighting some of the scheduled sessions that will share important data and research from around the globe.

Note: The following list of presentations is in alphabetical order by company and will be updated as more information becomes available.

The company will share results from its clinical studies of investigational oral gildeuretinol for the treatment of Stargardt disease (TEASE) and geographic atrophy secondary to age-related macular degeneration (SAGA) at the 2025 ARVO annual meeting.

age-related macular degeneration (wet AMD)

. It was previously announced that the phase 2 clinical data demonstrated that MGB administration lowered production of subretinal fluid, reducing or eliminating the need for intravitreal anti-VEGF treatment in both the study eye and fellow eye in wet AMD and DME subjects with bilateral disease.

The company will have presentations that highlight its advancing ocular gene therapy, including the development of its proprietary VSaf AAV manufacturing platform and therapeutic candidate ABI-201, a single AAV vector carrying 3 functional genes to treat dry AMD.

Data from EyePoint has been accepted for presentation at the upcoming 2025 ARVO Annual Meeting. The company plans to showcase its clinical trial datasets for is phase 2 VERONA trial and phase 2 DAVIO 2 trial, which across multiple indications saw continued safety and efficacy, as well as the program’s de-risked study designs that reflect real-world patient populations.

Eyestem has recently shared that all patients across 3 cohorts in the company’s phase 1 trials of its investigational drug, Eyecyte-RPE, in patients with geographic atrophy (GA) secondary to dry age-related macular degeneration (AMD) were dosed without any serious adverse events.

The data from cohort 1 of its phase 1/2a clinical trial evaluating RPESC-RPE-4W, a retinal pigment epithelium (RPE) cell therapy derived from adult retinal pigment epithelial stem cells (RPESCs).

The company is scheduled to participate at both the Eyecelerator and the 2025 ARVO annual meetings. Nanoscope's presentations will be centered around 126-week outcomes following treatment with its MCO-010 optogenetic therapy for retinitis pigmentosa (RP), the first and only therapy shown to restore vision in advanced RP patients via a one-time, standard intravitreal injection.

Companies announce presentations at upcoming 2025 ARVO Annual Meeting

A new therapeutic approach that combines eyelid pressure patching with the application of decellularized, dehydrated pure amniotic membrane basement membrane (AMBM), a type of amniotic membrane tissue (AMT), was highly successful and safe for healing persistent corneal epithelial defects,

 according to Kyle Linsey, MD, who is from the Cornea Service, Clearwater Eye and Laser Center, Clearwater, FL, and HCA Florida Bayonet Point Hospital, University of South Florida, Tampa.

Managing persistent corneal epithelial defects can be tricky, and, according to Linsey, typically consists of treatments such as frequent lubrication, immunomodulators, steroids, autologous serum or platelet-rich plasma tears, bandage contact lens, punctal occlusion, and in more advanced disease, pressure patching, epithelial debridement, scleral contact lenses, cenegermin, and AMT.

AMT offers a number of advantages to patients that includes rapid re-epithelialization of the persistent corneal epithelial defects in cases refractory to treatment,

 by addressing the ocular surface inflammation,

 at rates of re-epithelialization of 45.5% to 74.7%, independent of ulcer etiology.

 The treatment does not transfer viable stem cells

 but “supports damaged tissue, protects and shields defects from further degeneration or breakdown from external factors and promotes re-cellularization,

In addition, AMT stimulates proliferation and migration of limbal stem cells, suppresses neo-angiogenesis, inflammation, and scarring, contributes to AMT’s ability to support the healing of ocular surface disease

 and physically acts as a substrate for epithelial cell growth.

Multilayer AMT has been proposed for treating deep neurotrophic corneal ulcers

 and is more effective than autologous serum at healing corneal ulcers resulting from herpetic neurotrophic keratitis.

In his retrospective study, Linsey analyzed 144 eyes treated with either a single-layer or three-layer decellularized AMBA (Biovance 3L Ocular; Verséa Ophthalmics, Inc.) combined with a 24-hour eyelid pressure patch; 90% were treated with a single layer of AMBM and 10% with three layers of AMBM.

In the single-layer group, Linsey reported, all cases healed completely and the AMBM dissolved. In the three-layer group, all cases had improvements in the corneal staining; however, the AMBM did not dissolve in 20% to 30% of cases. No patients reported pain, discomfort, or infection.

This study found that combining eyelid pressure patching with AMT is a safe and effective approach for healing persistent corneal epithelial defects.

“AMT promotes epithelial cell proliferation, reduces inflammation and neuropathic pain, and limits scar formation.

 AMT can act as a mechanical barrier to protect the ocular surface, prevent evaporation and dryness, and maintain a stable tear film while serving as a scaffold for donor–recipient cell migration and integration.

 The integration of an eyelid pressure patch with dehydrated, decellularized AMBM treatment for advanced ocular surface disease leads to accelerated corneal healing and increased patient comfort,” Linsey concluded.

A novel therapeutic strategy combining eyelid pressure patching with amniotic membrane tissue (AMT) has proven effective and safe for treating persistent corneal epithelial defects. Traditional management of these defects includes various treatments, but AMT offers advantages such as rapid re-epithelialization, inflammation reduction, and support for healing. A retrospective study of 144 eyes showed complete healing with single-layer AMT and improvement with three-layer AMT, with no reported pain or infection. This approach enhances corneal healing, reduces inflammation, and increases patient comfort, making it a promising option for ocular surface disease management.

Amniotic membrane tissue offers a number of advantages to patients.
