Summary
Orbital compression syndrome, a rare complication of sickle beta-thalassemia, presented without a history of pain crisis. This case highlights a unique presentation of sickle cell disease (SCD) involving orbital hematomas.
Area of Science:
- Ophthalmology
- Hematology
- Neurology
Background:
- Orbital compression syndrome (OCS) presents with ocular and extraocular dysfunction due to various orbital pathologies.
- Ocular manifestations of sickle cell disease (SCD) are infrequent, making OCS a rare presentation.
- Sickle beta-thalassemia is a hemoglobinopathy that can lead to diverse clinical complications.
Observation:
- A 17-year-old male presented with bilateral proptosis, chemosis, and restricted ocular movements without prior pain crisis or transfusion history.
- Funduscopic examination revealed macular edema and venous engorgement, indicative of ocular compromise.
- Peripheral smear confirmed sickle cells, and CT scans identified orbital subperiosteal and frontal epidural hematomas.
Findings:
- The patient was diagnosed with sickle beta-thalassemia via High-Performance Liquid Chromatography (HPLC) and mutation studies.
- Diagnosis of orbital compression syndrome was established based on clinical presentation and imaging findings.
- The absence of a prior vaso-occlusive crisis distinguished this case from typical SCD presentations.
Implications:
- This case underscores the importance of considering SCD in the differential diagnosis of OCS, even without a history of crisis.
- Early recognition and appropriate management, including transfusions and hydroxyurea, led to a full recovery.
- Further research into the pathophysiology of SCD-related OCS may improve diagnostic and therapeutic strategies.
