Beschreibung
Inclusion Criteria:
- Retinal vascular and metabolic-related diseases: Diabetic Retinopathy (DR, including NPDR and PDR), Retinal Vein Occlusion (RVO), Hypertensive Retinopathy.
- Degenerative diseases: Age-related Macular Degeneration (including dry and wet forms), Pathologic Myopia (PM), Polypoidal Choroidal Vasculopathy (PCV).
- Immune-mediated and inflammatory eye diseases: Uveitis (including primary and secondary), Optic Neuritis, Mooren's Ulcer, and corneal melting associated with systemic immune diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus).
- Anterior segment and ocular surface syndromes: Various types of Dry Eye Disease (DED), Keratoconus, Glaucoma (especially cases with chronic inflammation or long-term medication use).
- Developmental fundus diseases in children and adolescents: Coats' Disease, Familial Exudative Vitreoretinopathy (FEVR), Retinopathy of Prematurity (ROP).
- Patients with a confirmed diagnosis of fundus diseases, including Diabetic Retinopathy, Pathologic Myopia, Age-related Macular Degeneration, Coats' Disease, Familial Exudative Vitreoretinopathy (FEVR), Retinopathy of Prematurity (ROP), and other adult or pediatric fundus diseases.
- Ability to cooperate with study examinations, including acceptance of Ultra-Widefield (UWF) fundus photography, OCT/OCTA, AOSLO, corneal confocal microscopy, meibomian gland function assessment, corneal esthesiometry, and tear film function tests. Image quality must meet analytical standards.
- Availability of complete or follow-up accessible ophthalmic medical records.
- Blood pressure ≤ 160/100 mmHg (to avoid exacerbating ischemia due to uncontrolled hypertension).
Exclusion Criteria:
- Recent (within the past 3 months) corneal/conjunctival acute inflammation, ocular surgery, or ocular trauma; or presence of corneal alterations (e.g., contact lens wear).
- Fundus images that are uninterpretable or severely obscured (e.g., vitreous hemorrhage).
- Use of medications affecting tear secretion (e.g., antihistamines, antidepressants) within the past 30 days.

Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Tear Break-Up Time
Zeitfenster: Baseline and within 30 days post-procedure
|
The time from the last complete blink to the appearance of the first dry spot on the cornea.
|
Baseline and within 30 days post-procedure
|
|
Dry Eye Questionnaire-5
Zeitfenster: Baseline and within 30 days post-procedure
|
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.
|
Baseline and within 30 days post-procedure
|
|
Meibomian Gland Dropout
Zeitfenster: Baseline and within 30 days post-procedure
|
Meibomian gland dropout will be measured using infrared meibography.
|
Baseline and within 30 days post-procedure
|
|
Blink Rate
Zeitfenster: Baseline and within 30 days post-procedure
|
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.
|
Baseline and within 30 days post-procedure
|
|
Lipid Layer Thickness
Zeitfenster: Baseline and within 30 days post-procedure
|
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.
|
Baseline and within 30 days post-procedure
|
|
Tear Meniscus Height
Zeitfenster: Baseline and within 30 days post-procedure
|
Tear meniscus height refers to the vertical height of the tear volume accumulated along the lower eyelid margin.
|
Baseline and within 30 days post-procedure

Central Subfield Thickness
Zeitfenster: Baseline and within 30 days post-procedure
|
Central subfield thickness refers to the thickness of the retina at the fovea.
|
Baseline and within 30 days post-procedure
|
|
Subfoveal Choroidal Thickness
Zeitfenster: Baseline and within 30 days post-procedure
|
Subfoveal choroidal thickness refers to the thickness of the choroid directly beneath the fovea.
|
Baseline and within 30 days post-procedure
|
|
Subretinal Fluid
Zeitfenster: Baseline and within 30 days post-procedure
|
Subretinal fluid refers to fluid accumulation in the potential space between the neurosensory retina and the retinal pigment epithelium.
|
Baseline and within 30 days post-procedure
|
|
Intraretinal Fluid
Zeitfenster: Baseline and within 30 days post-procedure
|
Intraretinal fluid refers to fluid accumulation within the retinal layers, typically appearing as cystoid spaces.
|
Baseline and within 30 days post-procedure
|
|
Pigment Epithelial Detachment Height
Zeitfenster: Baseline and within 30 days post-procedure
|
Pigment epithelial detachment height refers to the maximal vertical height of separation of the retinal pigment epithelium from the underlying Bruch's membrane.
|
Baseline and within 30 days post-procedure
