NCT07386678
Disease or general study area: Uncomplicated rhegmatogenous retinal detachment (RRD) and risk of proliferative vittroretinopathy (PVR) Purpose and nature of the study: 1. Characterise the cytokine profile of vitreous fluid in uncomplicated RRD. 2. Develop a risk model to predict development of PVR after retinal detachment surgery using imaging and molecular biomarkers. 3. To develop deep learning/artificial intelligence (AI) models for PVR detection in retinal detachment. Inclusion criteria: 50 adult ( ≥18 years) patients with uncomplicated rhegmatogenous retinal detachments without PVR. What participating will involve: Pre- and post-operative assessments and intervention will follow standard of care for patients with rhegmatogenous retinal detachments. Additional intervention will include non-invasive imaging of anterior chamber flare, vitreous, wide-field retina, macula optical coherence tomography (OCT) and macula OCT-angiography (OCT-A) as well as, seeking participant's consent on collecting their vitreous fluid at time of their surgery for cytokine analysis.

Patients with uncomplicated rhegmatogenous retinal detachment will be recruited. All eyes will underwent 23G PPV with silicon oil tamponade. The eyes will be classified into two groups according to the timing of ILM peeling. Group A, ILM peelin will be performed during the first intervention, while in group B, it will be done at the time of silicon oil extraction.

Intravitreal topotecan exhibits strong anti-inflammatory, anti-proliferative, and anti-fibrotic properties, making it a promising option for preventing and treating proliferative vitreoretinopathy in rhegmatogenous retinal detachment. Preclinical studies have demonstrated its efficacy in proliferative vitreoretinopathy models, where no adverse events have been reported for doses of 5 µg to 30 µg. This prospective, matched cohort study aims to assess the therapeutic efficacy and safety of intravitreal topotecan for preventing and treating proliferative vitreoretinopathy in rhegmatogenous retinal detachment patients.
