Through a systematic observational study, the intrinsic connections and patterns between the occurrence and development of common blinding retinal diseases such as diabetic retinopathy, pathological myopia, and age-related macular degeneration and the changes in fine parameters of the anterior structure of the eye are deeply explored. To achieve this goal, investigators will adopt cutting-edge multimodal imaging technology to simultaneously collect precise data from ocular surface and fundus of participants. By integrating and analyzing these multi-dimensional information from different parts of the same eye, investigators will build a high-quality and standardized ocular surface-fundus associated image database. This database not only aims to reveal potential ocular surface biomarkers that can be used for early warning or auxiliary diagnosis, but also lays a solid data foundation for the future development of artificial intelligence-assisted diagnostic tools and the establishment of a brand-new ocular surface-fundus integrated diagnosis and treatment assessment model.

RECRUITINGTear Break-Up Time
The time from the last complete blink to the appearance of the first dry spot on the cornea.
Time frame: Baseline and within 30 days post-procedure
Dry Eye Questionnaire-5
The DEQ-5 comprises five items assessing the frequency of dryness, discomfort, and watery eyes, as well as the late-day intensity of dryness and discomfort. Patients rate each item on a 0-4 or 0-5 scale, and the total score is summed. Higher scores indicate greater dry eye symptom severity.
Time frame: Baseline and within 30 days post-procedure
Meibomian Gland Dropout
Meibomian gland dropout will be measured using infrared meibography.
Time frame: Baseline and within 30 days post-procedure
Blink Rate
Blink rate will be measured using a video recording system under natural blinking conditions. The number of complete blinks and incomplete blinks per minute will be counted separately.
Time frame: Baseline and within 30 days post-procedure
Lipid Layer Thickness
Lipid layer thickness refers to the thickness of the lipid layer of the tear film, which is the outermost layer of the precorneal tear film.
Time frame: Baseline and within 30 days post-procedure
Tear Meniscus Height
Tear meniscus height refers to the vertical height of the tear volume accumulated along the lower eyelid margin.
Time frame: Baseline and within 30 days post-procedure
Central Subfield Thickness
Central subfield thickness refers to the thickness of the retina at the fovea.
Time frame: Baseline and within 30 days post-procedure
Subfoveal Choroidal Thickness
Subfoveal choroidal thickness refers to the thickness of the choroid directly beneath the fovea.
Time frame: Baseline and within 30 days post-procedure
Subretinal Fluid
Subretinal fluid refers to fluid accumulation in the potential space between the neurosensory retina and the retinal pigment epithelium.
Time frame: Baseline and within 30 days post-procedure
Intraretinal Fluid
Intraretinal fluid refers to fluid accumulation within the retinal layers, typically appearing as cystoid spaces.
Time frame: Baseline and within 30 days post-procedure
Pigment Epithelial Detachment Height
Pigment epithelial detachment height refers to the maximal vertical height of separation of the retinal pigment epithelium from the underlying Bruch's membrane.
Time frame: Baseline and within 30 days post-procedure
