About this trial
This study investigates the prognostic value of macular neovascularization (MNV) subtypes in patients treated with pneumatic displacement for submacular hemorrhage. The researchers will compare anatomical and functional outcomes (visual acuity) between PCV, RAP, and other MNV forms within a Caucasian cohort to identify subtype-specific predictors of recovery.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients undergoing pneumatic displacement (PD) for submacular hemorrhage (SMH), secondary to macular neovascularization (MNV)
Age 50 years or older at the time of SMH diagnosis
Caucasian ethnicity
SMH involving the central or internal ring of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid (within a 3 mm circumference centered on the fovea)
Disqualifiers
SMH estimated to be present for more than 15 days at the time of diagnosis
SMH secondary to conditions other than MNV
Presence of proliferative diabetic retinopathy in the study eye
Aphakia in the study eye
Trial population
The study population consists of Caucasian patients, aged 50 years or older, diagnosed with submacular hemorrhage (SMH) secondary to macular neovascularization (MNV). All participants underwent pneumatic displacement treatment at the Multizonal Ophthalmology Unit of the Provincial Agency for Healthcare Services (APSS) in Trento and Rovereto, Italy, between December 1, 2016, and May 31, 2023.

Trial outcomes
Primary outcomes
Anatomical success rate of pneumatic displacement
Percentage of patients achieving successful subretinal hemorrhage displacement, defined as the absence of subretinal blood within the internal ring of the ETDRS grid (3 mm centered on the fovea) at the first post-operative OCT
Change in Best-Corrected Visual Acuity (BCVA)
Evaluation of the difference in visual acuity from baseline to the 6-month follow-up. Snellen chart measurements will be converted to LogMAR for statistical analysis.
Secondary outcomes
Change in Central Retinal Thickness
Measurement of retinal thickness (in microns) using Spectralis HRA+OCT to evaluate the anatomical response to treatment.
