AbstractPurposeTo report a comparison analysis of accelerated corneal cross-linking (A-CXL) treatment for progressive keratoconus patients in different pediatric age groups.Study designRetrospective, cross-sectional.MethodsPatients with progressive keratoconus aged  ≤ 18 were retrospectively reviewed. Forty-one eyes of 41 patients were included in the study. Patients were divided into two groups according to their age (≤ 14 years and 15–18 years). All patients underwent epithelium-off A-CXL protocol. Acquired data were compared between the two grou ps.ResultsThe mean age was 14.3  &p...

ABSTRACT Purpose: A significant transient increase in intraocular pressure in individuals wearing swimming goggles has been demonstrated in previous studies. These findings suggested that wearing swimming goggles could represent a significant risk factor for worsening of corneal parameters in patients with keratoconus who swim regularly. The aim of this study was to investigate corneal parameters in patients with keratoconus after wearing swimming goggles. Methods: Comprehensive ocular examinations were performed on 74 eyes of 37 patients with keratoconus. Measurements of the corneal front keratometry values (Kflat, Ksteep...

We present a child with ASD who developed progressive KC following standard corneal cross-linking (CXL), most likely because of abnormal ER associated with allergy and repetitive behavior due to ASD symptoms. Patient concerns: A 14-year-old boy was referred to our clinic because of asymmetric visual acuity reduction. Diagnosis: The child was diagnosed as having keratoconus. He had a strong ER habit. The child had been previously diagnosed as having ASD. Interventions: Corneal cross-linking was performed in both the eyes. On account of keratoconus progression, most likely associated with persistent ER habit, he was...

Previous studies have reported that keratoconus is the main indication for keratoplasty surgery [1,2]. Keratoconus is the most common primary corneal ectatic disorder; it is typically a bilateral and asymmetrical corneal anomaly characterized by localized corneal thinning with a conical shaped protrusion [3,4]. This disease may have significant adverse effects on vision when the presence of high irregular astigmatism and an increase in higher-order aberrations appear, thereby affecting patients ’ quality of life negatively [5,6].
