TYPE 2 (SUBRETINAL) NEOVASCULARIZATION IN AGE-RELATED MACULAR DEGENERATION ASSOCIATED WITH PURE RETICULAR PSEUDODRUSEN PHENOTYPE
Bibliographic record
Abstract
In Brief Purpose: To report the association of pure type 2 neovascularization (NV) in age-related macular degeneration occurring almost exclusively in patients with reticular pseudodrusen. Methods: An observational retrospective cohort study of all eyes receiving antivascular endothelial growth factor therapy for newly diagnosed neovascular age-related macular degeneration by a single practitioner over a 6-year period. Only patients with treatment-naive, pure type 2 NV who also had either pre-neovascular imaging of the study eye or imaging of a nonneovascular fellow eye available to determine baseline characteristics including drusen type and choroidal thickness were incuded. Results: Of 694 patients treated for neovascular age-related macular degeneration, only 8 met the inclusion criteria with pure type 2 NV. Of these, 7 (88%) had exclusively reticular pseudodrusen (5 in the nonneovascular fellow eye, 2 in the study eye before developing NV). Six (75%) patients in the affected neovascular eye and 6 (75%) in the fellow nonneovascular eye had choroidal thickness <120 μm. Mean follow-up was 46 months (range, 3.0–63.3). Best-corrected vision improved from 20/89 (range, 20/30–20/796) at baseline to 20/60 (range, 20/20–20/399) at last follow-up. Conclusion: Pure type 2 NV is rare in age-related macular degeneration, occurring almost exclusively in patients with reticular pseudodrusen and thin choroids. Pure Type 2 neovascularization is rare in age-related macular degeneration. Reticular pseudodrusen are located above the retinal pigment epithelium best visualized by near-infrared reflectance and spectral domain optical coherence tomography. The authors describe the occurrence of pure Type 2 neovascularization in age-related macular degeneration that seems to occur almost exclusively in patients presenting with reticular pseudodrusen compared with other drusen phenotypes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
