Introduction:

Corticosteroid-induced glaucoma, commonly known as steroid glaucoma, is a potential complication that may occur after refractive eye surgeries involving the use of corticosteroid eye drops for post-operative inflammation control. This comprehensive article aims to provide a thorough understanding of corticosteroid-induced glaucoma after refractive surgery, its risk factors, symptoms, diagnosis, management, and preventive measures.

Understanding Steroid Glaucoma:

Corticosteroids are commonly used to manage post-operative inflammation and promote healing after refractive eye surgeries such as LASIK, PRK, or cataract surgery. However, prolonged and indiscriminate use of corticosteroid eye drops may lead to an increase in intraocular pressure (IOP), resulting in steroid glaucoma. This elevation in IOP can damage the optic nerve and lead to vision loss if not promptly addressed.

Risk Factors for Steroid Glaucoma:

Several factors can increase the risk of developing steroid glaucoma after refractive surgery:

• Prolonged Corticosteroid Use: Extended use of corticosteroid eye drops beyond the recommended duration increases the risk of IOP elevation.
• High-dose Steroid Eye Drops: The risk of steroid glaucoma is higher with high-dose corticosteroid eye drop regimens.
• Pre-existing Glaucoma: Individuals with pre-existing glaucoma or ocular hypertension are more susceptible to steroid-induced IOP elevation.
• Family History: A family history of glaucoma may predispose individuals to steroid glaucoma.

Symptoms of Steroid Glaucoma:

Steroid glaucoma may be asymptomatic in the early stages, making regular post-operative follow-up crucial to detect IOP changes. As the condition progresses, individuals may experience:

• Gradual Vision Loss: Vision may become blurry or hazy due to optic nerve damage.
• Halos around Lights: Seeing halos around lights, especially in low-light conditions.
• Eye Pain: Experiencing mild to moderate eye discomfort or pain.
• Headaches: Frequent headaches, especially in the frontal area.

Diagnosis of Steroid Glaucoma:

Regular IOP monitoring during post-operative follow-up visits is essential to detect any elevation in intraocular pressure. A diagnosis of steroid glaucoma is confirmed if there is a significant increase in IOP beyond the normal range after prolonged corticosteroid use. Additionally, comprehensive eye examinations, including optic nerve evaluation and visual field testing, help assess the extent of glaucoma damage.

Management of Steroid Glaucoma:

Prompt management of steroid glaucoma is crucial to prevent irreversible vision loss. Treatment options may include:

• Discontinuation or Tapering of Steroid Eye Drops: In milder cases, reducing the frequency or discontinuing corticosteroid eye drops may lead to IOP normalization.
• Glaucoma Medications: Eye drops or oral medications to lower intraocular pressure may be prescribed.
• Surgery: In more severe cases, laser procedures or conventional glaucoma surgery may be necessary to lower IOP and preserve vision.

Preventive Measures:

To reduce the risk of steroid glaucoma, following these preventive measures is essential:

• Regular Follow-up Visits: Consistent and regular post-operative follow-up visits allow for timely detection of IOP changes.
• Corticosteroid Management: Adhering to the prescribed corticosteroid regimen and avoiding prolonged use beyond the recommended duration is crucial.
• Personal and Family History: Disclosing personal and family history of glaucoma to the eye care provider allows for a more comprehensive evaluation of the individual's glaucoma risk.

Conclusion:

Steroid glaucoma is a potential complication after refractive surgery, emphasizing the importance of careful corticosteroid management and regular follow-up visits. Early detection and prompt management are vital to prevent irreversible vision loss and preserve ocular health.
