1 | open-ended | <image>What lesions are present in the retinal fundus of the left eye showing moderate non-proliferative diabetic retinopathy? This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Microaneurysm</type><location>Peripheral Nasal</location></lesion><lesion><type>Soft Exudate</type><location>Peripheral Inferior, Outer Superior</location></lesion><lesion><type>Hemorrhage</type><location>Inner Inferior, Outer Inferior</location></lesion> | <reason>The question asks which lesions are visible in a left-eye fundus image with moderate non-proliferative diabetic retinopathy, so the image should be examined for typical diabetic retinopathy lesions, including microaneurysms, hemorrhages, and ischemic/exudative changes. Small red dot-like lesions are identified ... | <answer>Microaneurysms, soft exudates, and haemorrhages are present.</answer> | images/img_000001.png |
2 | open-ended | <image>Based on the retinal findings in this image, what is the diagnosis and how is the patient's central vision likely to be affected? This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Hemorrhage</type><location>Central Fovea</location></lesion> | <reason>The question asks for both the diagnosis and the likely impact on central vision, so the key finding is whether the lesion involves the macular center. In this image, hemorrhage is located at the central fovea, which is the most critical area for sharp central vision. In the setting of AMD, foveal hemorrhage su... | <answer>The diagnosis is age-related macular degeneration with central foveal hemorrhage. Because the hemorrhage involves the fovea, the patient’s central vision is likely to be significantly affected, causing reduced central visual acuity and possible visual distortion.</answer> | images/img_000002.jpg |
3 | open-ended | <image>What is the retinopathy grade observed in the left eye fundus image, and what does it imply regarding the severity and progression of diabetic retinopathy? This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Microaneurysm</type><location>Peripheral Nasal, Peripheral Superior, Peripheral Temporal, Outer Nasal, Outer Superior</location></lesion><lesion><type>Hemorrhage</type><location>Peripheral Superior, Peripheral Temporal, Outer Nasal, Outer Superior</location></lesion> | <reason>The question asks for the retinopathy grade and its clinical implication, so the image should be evaluated for diabetic retinopathy lesions and their distribution. Microaneurysms are present in multiple regions, including the peripheral nasal, peripheral superior, peripheral temporal, outer nasal, and outer sup... | <answer>The retinopathy grade is DR grade 2, consistent with moderate non-proliferative diabetic retinopathy. This indicates established diabetic retinal vascular damage with multiple microaneurysms and hemorrhages, but without proliferative neovascularization. The disease is more than mild and requires monitoring beca... | images/img_000004.jpg |
4 | open-ended | <image>What are the key lesions observed in this fundus image? This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Scar</type><location>Central Fovea</location></lesion> | <reason>The question asks for the key visible lesion rather than the final disease diagnosis, so the image should be summarized based on the annotated retinal abnormality and its location. The main lesion identified is a scar located at the central fovea. Because the central fovea is the anatomical center of the macula... | <answer>A scar is observed at the central fovea.</answer> | images/img_000005.jpg |
5 | open-ended | <image>Please analyze this retinal image clinically. This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Cup-to-disc Ratio</type><location>Optic Cup, Optic Disc</location></lesion> | <reason>The image should be assessed systematically, including the optic nerve head, macula, retinal vessels, and peripheral retina. The retinal background appears largely unremarkable, with no visible hemorrhages, microaneurysms, hard exudates, cotton-wool spots, drusen, or atrophic lesions. The macular region and ret... | <answer>The fundus image is otherwise largely normal, with no obvious retinal vascular, macular, hemorrhagic, or exudative lesions. The key finding is an increased cup-to-disc ratio involving the optic cup and optic disc, which suggests possible glaucoma risk and requires further optic nerve evaluation.</answer> | images/img_000006.jpg |
6 | open-ended | <image>Describe the location and clinical significance of the lesion shown in this fundus image. This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Atrophy</type><location>Outer Nasal</location></lesion> | <reason>The question asks for both the lesion location and its clinical significance, so the key is to identify the lesion type and determine whether it involves the macular center. The annotated lesion is atrophy located in the outer nasal region. This indicates localized retinal or chorioretinal tissue loss outside t... | <answer>A focal atrophic lesion is present in the outer nasal retina. Since it is outside the central fovea, it is unlikely to directly threaten central vision, but it indicates localized retinal or chorioretinal degeneration that should be clinically monitored.</answer> | images/img_000007.jpg |
7 | open-ended | <image>Please analyze this retinal image clinically. This is an open-ended question. Please output its answer with a detailed reason and corresponding visual location. | <lesion><type>Tigroid Fundus</type><location>entire retina</location></lesion> | <reason>The question asks for a clinical analysis of the retinal image, so the overall fundus appearance should be assessed rather than focusing only on focal lesions. The annotated finding is a tigroid fundus pattern involving the entire retina. This appearance reflects diffuse thinning of the retinal pigment epitheli... | <answer>The fundus image shows a diffuse tigroid fundus pattern involving the entire retina, suggesting high myopia-related fundus change. </answer> | images/img_000008.jpg |
8 | open-ended | <image>What abnormalities are visible in this retinal image? This is an open-ended question.

Multiple hard exudates are present across the inner, outer, and peripheral retinal regions, indicating retinal vascular leakage. Microaneurysms a... | <answer>The left eye is diagnosed as moderate non-proliferative diabetic retinopathy, corresponding to ICDR grade 2. This is supported by microaneurysms, multi-regional hemorrhages, and widespread hard exudates, without evidence of proliferative neovascularization.</answer> | images/img_000010.jpg |
10 | open-ended | <image>Describe the pathological features in this fundus image. | <lesion><type>Drusen</type><location>Inner Nasal, Outer Nasal</location></lesion> | <reason>The question asks for the pathological features visible in the fundus image, so the response should focus on the identified lesion type and its retinal location. The annotated abnormalities are drusen located in the inner nasal and outer nasal regions. Drusen appear as yellowish subretinal deposits and are clin... | <answer>The image shows drusen in the inner nasal and outer nasal regions. These yellowish deposits represent degenerative retinal changes and may be associated with age-related macular degeneration. The central fovea is not directly involved based on the provided lesion locations.</answer> | images/img_000011.jpg |
11 | closed-ended | <image>Is the central fovea directly affected by retinal hemorrhage in this left eye image? This is a closed-ended question. Please output its answer (yes or no) with a detailed reason and corresponding visual location. | <lesion><type>Hemorrhage</type><location>Inner Inferior, Peripheral Inferior, Peripheral Temporal, Outer Inferior</location></lesion> | <reason>The question specifically asks whether retinal hemorrhage directly involves the central fovea. The annotated hemorrhages are located in the inner inferior, peripheral inferior, peripheral temporal, and outer inferior regions. None of these locations correspond to the central fovea. Therefore, although retinal h... | <answer>No</answer> | images/img_000012.jpg |
