Assessing posterior ocular structures in β-thalassemia minor

Area of Science:

• Ophthalmology
• Genetics
• Hematology

Background:

• Beta-thalassemia minor is a common inherited blood disorder.
• Ocular manifestations of beta-thalassemia minor are not well-established.
• Understanding these effects is crucial for comprehensive patient care.

Purpose of the Study:

• To investigate the impact of beta-thalassemia minor on ocular structures.
• Specifically examining choroidal, macular, and retinal nerve fiber layer thickness.

Main Methods:

• Recruited 40 patients with beta-thalassemia minor and 44 healthy controls.
• Utilized spectral-domain optical coherence tomography for ocular measurements.
• Analyzed correlations between hemoglobin levels and ocular parameters.

Main Results:

• Significantly lower mean subfoveal, nasal, and temporal choroidal thickness in patients with beta-thalassemia minor.
• Significantly lower paracentral macular thicknesses (superior, inferior, temporal, nasal) compared to controls.
• No significant differences in peripapillary retinal nerve fiber layer thickness were observed.

Conclusions:

• Patients with beta-thalassemia minor exhibit reduced choroidal and macular thickness.
• These findings highlight potential ocular structural changes in beta-thalassemia minor.
• Further research may elucidate the clinical significance of these observed differences.
