Altris AI OCT scan analysis for Fluids and Geographic Atrophy tracking in optometry

Jan. 15, 2025

Altris AI, a provider of artificial intelligence for OCT scan analysis, unveiled additional quantification features for Fluids and Geographic Atrophy (GA) tracking on its web platform.

Altris AI currently detects over 70 retina pathologies and biomarkers. However, the company said it decided to enhance its capabilities by adding additional Fluids and GA quantification and tracking functionalities, recognizing that eyecare specialists frequently work with these conditions.

These advancements are designed to empower eyecare professionals (ECPs) with tools for diagnosing and managing retinal diseases.

By integrating AI-driven quantitative tracking and progression monitoring, Altris AI says it “enables specialists to deliver more personalized and effective treatments, ultimately enhancing patient outcomes.”

Fluid Quantification and Progression Tracking

The presence of fluids such as Intraretinal Cystoid Fluid (IRC), Diffuse Edema, Subretinal Fluid (SRF) and Serous Retinal Pigment Epithelium (RPE) Detachment are critical biomarkers for conditions like nAMD, DME, DR and RVO.

Altris points out that accurate detection, quantification and tracking of these fluids are essential for monitoring disease activity, evaluating treatment efficacy and making informed prognoses.

“We created specialized more detailed functions which detect these biomarkers for more specific and accurate tracking. The AI algorithm was additionally trained to work directly with fluids considering the importance of these biomarkers for accurate diagnostics,” Altris AI stated in a press release.

Altris AI’s advanced algorithms, trained on millions of OCT scans, are designed to provide precise and objective fluid analysis.

Each of the four fluid types is localized and color-coded for clarity. Quantitative metrics such as volume, area and ETDRS grids (1, 3, and 6 mm) are calculated and presented in mm3 or nanoliters for comprehensive evaluation.

The Progression Tracking feature offers historical trend analysis with intuitive visualizations through graphs and percentages. For instance, if Cystoid Fluid (IRC) increases in volume, ECPs can immediately identify and address the change.

Altris says it also improved the accuracy of a critical step in its AI pipeline: the fovea and central scan detection.

Altris says its updated AI model is much more robust in detecting fovea zone and central scan now. Especially in cases when the center cannot be distinguished due to pathology presence or other reasons, the model is trained to analyze the whole surface and find reference locations from which a central scan could be determined.

The new model can find an accurate center in 95 percent of cases. In other situations, it can efficiently estimate the center location (as opposed to a simple analysis flow used by ECPs where the geometrical center is selected). This advancement significantly enhances the precision of GA detection.


Further Progression Tracking enhances GA management by visualizing changes over time, supporting timely and accurate treatment decisions. By streamlining workflows and providing actionable insights, this feature helps ECPs make informed choices and potentially preserve vision in GA patients.

Dr. Maria Znamenska, MD, PhD, and a Chief Medical Officer at Altris AI, commented:

“We listened to our clients and introduced Fluid and GA tracking features. In 2025, eye are specialists will have the tools to combine their expertise with next-generation AI technology to tackle conditions that threaten vision effectively. Our formula is simple: detect, quantify, and track fluids, GA and 70+ retina pathologies and biomarkers for better patient outcomes. ”
