Clinical trials

Glaucoma is one of the leading causes of irreversible blindness worldwide. Early diagnosis is crucial to prevent vision loss, but current diagnostic pathways require multiple specialist visits and tests, leading to long waiting times and delayed diagnosis. This study aims to evaluate the accuracy of GlaukomAI, an artificial intelligence (AI)-based software that analyzes fundus photographs of the eye to detect glaucoma at an early stage. The study is conducted at IRCCS Fondazione G. B. Bietti (Rome, Italy) and is structured in two phases: * Phase 1 enrolls 200 participants (100 with diagnosed glaucoma and 100 healthy controls) to assess how accurately GlaukomAI can distinguish between glaucoma and healthy eyes, compared to the judgment of a panel of three expert glaucoma specialists. * Phase 2 enrolls 1,000 consecutive outpatients to evaluate whether GlaukomAI can correctly identify patients who need referral to a glaucoma specialist, and to compare its performance with that of non-specialist ophthalmologists. Participants undergo a single study visit including standard ophthalmic examinations (visual acuity, eye pressure measurement, visual field test, OCT, and fundus photography). No investigational drugs or invasive procedures are involved. The results of this study will provide evidence to support the integration of AI-based tools into routine glaucoma screening pathways, with the goal of reducing diagnostic delays and improving access to care.

This prospective interventional translational study aims to identify and validate protein biomarkers associated with major ophthalmological diseases, including age-related macular degeneration, diabetic retinopathy (DR), and retinal detachment (RD). A total of approximately 260 participants (cases and controls) will be enrolled at a single center. Biological samples, including peripheral blood, tears, aqueous humor, vitreous humor, and subretinal fluid, will be collected during routine clinical and surgical procedures. Advanced clinical proteomics approaches will be applied to characterize molecular signatures associated with disease onset, progression, and response to treatment. The study seeks to improve the understanding of disease pathophysiology and support the development of novel diagnostic and prognostic biomarkers in ophthalmology.

Purpose: The aim of this study is to evaluate the impact of visual rehabilitation in visually impaired patients with advanced AMD by the use of questionnaires on the anxiety and depression status. Study design: prospective observational study. The study is carried out at the IRCCS Fondazione G.B.Bietti and at the UO Visual Rehabilitation, S. Alessio - Margherita di Savoia. Study procedures: Visit 1 (screening visit, at IRCCS Fondazione Bietti) After signing the informed consent, all patients received a complete ophthalmological examination, non-invasive diagnostic tests as optical coherence tomography, autofluorescence and microperimetry, and have to complete the questionnaires on the state of anxiety and depression (GAD-7 and PHQ-9). Visit 2 (at the Sant'Alessio Institute) for a 60-day visual rehabilitation program scheduled in 5 group meetings. Visit 3 (end-of-study visit, at IRCCS Fondazione G.B. Bietti) complete ophthalmological examination, as per clinical practice, non-invasive diagnostic tests such as microperimetry, optical coherence tomography and autofluorescence and administration of the Patient Health Questionnaire-9 (PHQ-9) questionnaires for depression and the General Anxiety Disorder (GAD-7) questionnaires for anxiety.

The purpose of this prospective, longitudinal, single-center observational study is to identify, describe, and measure the morpho-functional characteristics and modifications of the retina and choroid using advanced multimodal imaging techniques. The study will evaluate patients affected by retino-choroidal diseases and compare them with healthy controls over a 5-year follow-up period to track the evolution of these parameters over time.

This study evaluates whether a low-energy laser treatment called photobiomodulation (PBM) can improve visual function and retinal structure in patients with age-related macular degeneration (AMD) who have reticular pseudodrusen. PBM is a non-invasive therapy that uses specific wavelengths of light to stimulate cellular activity and reduce inflammation without causing tissue damage. Participants will be randomly assigned to receive either active PBM treatment or a sham (inactive) treatment. The study will assess changes in visual performance under low-light conditions and retinal structure over a 12-month period. The goal is to determine whether PBM can slow disease progression and improve visual function in patients with early stages of AMD.

The purpose of this study is to investigate whether subthreshold treatment with micropulsed laser can be effective in resolving macular edema in patients with inherited retinal dystrophy. Visits will be performed after 1, 3, 6, 9, 12, 18, and 24 months after treatment. Laser treatment will be performed on the day of the first visit, and its repetition at subsequent visits between months 3 and 12 will be evaluated. Evaluations of treatment effects will include: * comprehensive ophthalmologic examination * multifocal electroretinogram * OCT examination * OCT-angiography examination * retinography Primary endpoint. \- central retinal thickness, measured by OCT

The aim of the study is to evaluate the agreement between three different grids in detecting central visual field defect in early glaucoma patients with reduced ganglion cell layer thickness.
