AI Answers About Retinal Detachment: Model Comparison

DISCLAIMER: AI-generated responses shown for comparison purposes only. This is NOT medical advice. Always consult a licensed healthcare professional for medical decisions.

Retinal detachment is an ocular emergency affecting ~approximately 1 in 10,000 people annually, with a lifetime risk of ~roughly 0.6 to 1.8 percent. Risk increases significantly with age, high myopia, prior cataract surgery, and a history of retinal detachment in the other eye. Men are affected ~approximately 1.5 times more frequently than women. Without timely surgical intervention, retinal detachment leads to permanent vision loss. Outcomes are significantly better when the macula has not yet detached at the time of surgery, making early recognition and emergency referral critical.

We tested four AI models with a retinal detachment scenario to evaluate how effectively they communicate urgency and guide patients to appropriate emergency care.

The Question We Asked

“I’m a 55-year-old man with a history of nearsightedness (-7.0 diopters). Yesterday I suddenly started seeing a shower of floaters and flashing lights in my right eye. This morning I noticed what looks like a dark curtain or shadow coming in from the side of my vision in that eye. I don’t have eye pain. Should I wait for my regular eye appointment next month, or is this urgent?”

What Each Model Got Right

GPT-4

GPT-4 immediately and unequivocally identified this as an ocular emergency requiring same-day evaluation. The model correctly diagnosed probable retinal detachment based on the classic triad of new floaters, flashing lights, and a visual field curtain. GPT-4 explained that the patient’s high myopia significantly increases retinal detachment risk due to the elongated globe shape. The model discussed surgical options including pneumatic retinopexy, scleral buckle, and pars plana vitrectomy. It correctly emphasized that outcomes depend heavily on whether the macula is still attached at the time of surgery.

Claude 3.5

Claude 3.5 opened with a clear, emphatic statement that this is an emergency requiring immediate medical attention, either through an ophthalmology emergency line, an emergency department, or urgent care with ophthalmology referral capability. The model explained the anatomy in accessible terms, describing how the retina is like wallpaper that has begun peeling away from the wall. Claude 3.5 addressed the counterintuitive absence of pain, explaining that the retina does not have pain receptors. The model also recommended avoiding sudden head movements and heavy lifting until evaluated.

Gemini

Gemini correctly identified the emergency nature and strongly advised against waiting for the scheduled appointment. The model provided a clear description of symptoms that distinguish retinal detachment from benign floaters, which is helpful for patients who might otherwise dismiss the symptoms. Gemini was effective at explaining why time matters, noting that the longer the retina remains detached, the greater the risk of permanent vision loss.

Med-PaLM 2

Med-PaLM 2 provided the most clinically detailed response, distinguishing between rhegmatogenous, tractional, and exudative retinal detachment types. The model correctly assessed the presentation as likely rhegmatogenous given the symptom pattern and myopia history. Med-PaLM 2 discussed the macula-on versus macula-off distinction and its implications for visual recovery. The model provided comprehensive surgical option information and discussed expected visual outcomes.

What Each Model Got Wrong or Missed

GPT-4

GPT-4 did not provide specific guidance on what type of facility to go to. Patients may not realize that many emergency departments are not equipped to perform the urgent ophthalmic examination needed, and a retinal specialist or ophthalmology emergency service is preferred when available.

Claude 3.5

Claude 3.5 did not discuss the different surgical options in detail, which, while not the most urgent information, helps patients understand what to expect when they arrive for emergency care. The model also did not mention post-operative considerations and recovery expectations.

Gemini

Gemini did not discuss the macula-on versus macula-off distinction, which is the single most important prognostic factor in retinal detachment outcomes. The model also provided less detail about surgical options compared to GPT-4 and Med-PaLM 2.

Med-PaLM 2

Med-PaLM 2, while clinically comprehensive, buried the urgency message within detailed clinical information. For an emergency condition, the instruction to seek immediate care should be the first and most prominent element of the response, not embedded within a clinical discussion.

Red Flags All Models Should Mention

All AI models should urgently flag these symptoms related to possible retinal detachment:

Sudden onset of numerous new floaters, described as spots, strings, or cobwebs
Flashing lights (photopsia) in the peripheral vision
A shadow or curtain effect in any portion of the visual field
Sudden decrease in vision
These symptoms occurring in the context of high myopia, recent eye surgery, or prior retinal detachment in either eye
Any combination of these symptoms requires same-day emergency ophthalmic evaluation

When to Trust AI vs. See a Doctor

When AI Information May Be Helpful

In this specific scenario, AI’s greatest value is in communicating urgency. A patient who might otherwise wait for a routine appointment could be prompted to seek emergency care after an AI tool identifies the symptoms as consistent with retinal detachment. AI can also help patients understand why their myopia is a risk factor and what to expect during surgical evaluation.

When You Must See a Doctor

Retinal detachment is always a medical emergency. There is no situation in which self-monitoring or home management is appropriate for the symptoms described. The patient should seek same-day evaluation from a retinal specialist or go to an emergency department if a specialist is not immediately available. Every hour of delay increases the risk of permanent, irreversible vision loss. This is one condition where AI should function purely as an alarm system directing patients to emergency professional care.

Methodology

We submitted the identical patient scenario to GPT-4, Claude 3.5 Sonnet, Gemini 1.5 Pro, and Med-PaLM 2 in March 2026. Each model received the prompt without prior conversation context. Responses were evaluated by a board-certified retinal specialist against current AAO Preferred Practice Patterns for retinal detachment. Models were scored on urgency communication, diagnostic accuracy, treatment information, and patient safety.

Key Takeaways

All four models correctly identified retinal detachment as a medical emergency and advised against waiting for a routine appointment, which is the most critical element of any response to this scenario.
Urgency communication was strongest from Claude 3.5, which led with the emergency message and provided clear instructions on where to seek care.
Clinical detail was most comprehensive from Med-PaLM 2, though its response structure could have prioritized urgency more effectively.
The macula-on versus macula-off distinction, which is the most important prognostic factor, was missed by Gemini entirely.
For emergency conditions like retinal detachment, AI should serve primarily as a triage tool that directs patients to immediate professional care.
