Clinical Scorecard: Evaluation of Choroidal Thickness and Vascularity Following Corneal Crosslinking in Patients with Keratoconus
At a Glance
Category Detail
Condition Keratoconus Key Mechanisms Corneal collagen cross-linking (CXL) using riboflavin and UVA radiation to stabilize corneal ectatic disorders. Target Population Patients with progressive keratoconus, particularly young individuals. Care Setting Ophthalmology department in a university hospital.
Key Highlights
CXL effectively improves corneal strength and reduces irregular astigmatism. Choroidal thickness (CT) and choroidal vascular index (CVI) were evaluated post-CXL. No significant complications reported during or after CXL procedures. Guideline-Based Recommendations
Diagnosis
Clinical and topographic diagnosis of keratoconus. Use of SD-OCT for structural evaluation. Management
Accelerated CXL method with riboflavin and UVA irradiation. Post-operative care includes antibiotic and anti-inflammatory drops. Monitoring & Follow-up
Regular ophthalmological examinations including visual acuity and intraocular pressure. Risks
Potential corneal complications such as haze, infections, and endothelial damage. Patient & Prescribing Data
Patients with progressive keratoconus and specific inclusion criteria.
Topical moxifloxacin and loteprednol prescribed post-CXL.
Clinical Best Practices
Ensure high-quality SD-OCT scans for accurate measurement. Monitor systemic blood pressure before procedures. References
