Brief Summary

To investigate, using optical coherence tomography angiography (OCTA), the retinal and choriocapillaris vascular features in patients affected by Beta Thalassemia. Moreover we analyzed the structural retinal parameters (ganglion cell complex and retinal nerve fiber layer), using optical coherence tomography (OCT) in these patients

Outcome Measures

Primary Outcomes (1)

  • The measurements of retinal and choriocapillaris features in patients with Beta Thalassemia, using optical coherence tomography angiography.

    The parameters analyzed by optical coherence tomography angiography were: retinal and choriocapillaris vessel density

    Four months

Secondary Outcomes (1)

  • The measurements of retinal structural parameters in patients with Beta Thalassemia, using optical coherence tomography.

    Four months

Study Arms (2)

Patients with Beta Thalassemia

Patients with previous diagnosis of Beta Thalassemia

Diagnostic Test: Optical coherence tomography angiography

Control Group

Healthy fellow eyes without actual and previous ocular trauma

Diagnostic Test: Optical coherence tomography angiography

Interventions

Each subject underwent Optical coherence tomography angiography (a non-invasive, fast, diagnostic imaging technique)

Control GroupPatients with Beta Thalassemia

Eligibility Criteria

Age35 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

The participans were older than 35 years with diagnosis of Beta Thalassemia. They did not present other ophthalmological diseases.

You may qualify if:

  • age older than 35 years
  • diagnosis of Beta Thalassemia
  • absence of previous ocular surgery, congenital eye disease, high myopia (\>6 dioptres), actual or previous diagnosis of glaucoma, optic disc anomaly, macular or vitreoretinal diseases.
  • absence of significant lens opacities, low-quality OCT and OCT-A images.

You may not qualify if:

  • age older than 50 years
  • absence of diagnosis of Beta Thalassemia
  • presence of previous ocular surgery, congenital eye disease, high myopia (\>6 dioptres), actual or previous diagnosis of glaucoma, optic disc anomaly, macular or vitreoretinal diseases.
  • presence of significant lens opacities, low-quality OCT and OCT-A images.
