AAO preferred patterns often missed
- A 200-chart review from three academic glaucoma centers found doctors often missed core AAO care steps, even after the academy’s guidance had been updated. - The misses were basic but important — documenting disease stage and target pressure, setting follow-up intervals, and tying gonioscopy, imaging, and fields together. - That matters because glaucoma is chronic and often silent, so inconsistent documentation makes progression easier to miss and care harder to standardize.
Glaucoma care has a paperwork problem, but it is not just paperwork. The American Academy of Ophthalmology’s Preferred Practice Patterns are supposed to be the shared playbook for how clinicians diagnose, document, and monitor disease. A chart review highlighted by *Ophthalmology Times* showed that, in real clinics, that playbook was getting followed unevenly. That matters because glaucoma usually worsens slowly and quietly — if the record is vague, the disease can look stable right up until vision is gone. ### What are these AAO patterns, exactly? They are evidence-based practice guidelines. Not rigid rules for every patient, but a framework for what good eye care should include — history, exam elements, risk assessment, testing, treatment goals, and follow-up. The AAO updates them on a rolling basis and says they are meant to define the components of quality care, not just academic best intentions. ### What did the chart review actually look at? (ophthalmologytimes.com) The review covered 200 charts and 259 visits from three centers, focused on patients with open-angle glaucoma, suspected glaucoma, and angle-closure glaucoma. The charts had to involve visits after the September 2005 update of the AAO guidance, so this was not a case of judging old care by new rules. The point was simpler — were clinicians using the standard they already had? Turns out, not consistently. (aao.org) ### Where did the gaps show up? The weak spots were not exotic treatment decisions. They were the connective tissue of glaucoma care — disease stage, target intraocular pressure, follow-up planning, and whether different tests were being interpreted together instead of in silos. That last part matters a lot. A glaucoma patient’s gonioscopy, optic nerve appearance, retinal nerve fiber layer imaging, macular imaging, and visual field results are supposed to tell one story. If they live as separate checkboxes, progression gets easier to miss. (ophthalmologytimes.com) ### Why is “target IOP” such a big deal? Because glaucoma treatment is basically pressure management tied to damage risk. The AAO’s current POAG guidance still centers care on lowering intraocular pressure, even for patients whose untreated pressure sits in the normal range. If a chart never states the target, nobody can easily tell whether the patient is at goal, whether therapy is working, or whether “stable” just means nobody defined success. (ophthalmologytimes.com) ### Why does documentation change outcomes? Because glaucoma is a long game. Patients move between residents, attendings, optometrists, and surgeons. Visits get spaced out over months. Imaging platforms change. A clean note acts like a relay baton. A vague one drops the race. The older review even framed poor adherence as a systems issue across different academic settings, not just one doctor having an off day. (aao.org) ### Is this only a physician problem? Not really. It looks more like an operational problem. Another chart review in a resident clinic found decent overall compliance with many AAO elements, but weaker documentation for things like gonioscopy, central corneal thickness, optic nerve and nerve fiber layer analysis, visual fields, and especially patient education. So the pattern keeps repeating — the exam may partly happen, but the record does not always preserve the logic of care. (ophthalmologytimes.com) ### What would fix it? Probably not another lecture. Better templates would help more — required fields for stage and target IOP, explicit progression language, and note structures that force clinicians to reconcile pressure, disc appearance, OCT, and field data in one assessment. That is boring medicine, but it is the useful kind. ### Bottom line The real warning here is not that glaucoma specialists do not know glaucoma. (iovs.arvojournals.org) It is that clinics can drift away from their own standard in small, ordinary ways. In a disease defined by slow loss and long follow-up, those small misses add up.
