Intrastromal corneal ring segments for keratoconus patients: up to 12 years follow up.

PURPOSE: Intrastromal corneal ring segment (ICRS) implantation is a surgical technique developed with the purpose of avoiding the progression of corneal protrusion and is considered a viable option for managing patients with keratoconus as it stabilizes or improves vision thus delaying or excluding the need of more advanced surgical intervention such as penetrating keratoplasty. However, long term follow up is still limited to determine its actual success in achieving this goal. The current project aims to provide an extended follow up reporting a mean followup of around 5 years, extending up to 12.5 years. METHODS: We recruited patients who performed their ICRS between 2008 and 2013. We contacted patients for a follow up exam with a possible corneal tomography. For each patient, we obtained baseline pre operative data and latest follow up data which included visual acuity, subjective refraction, clinical slit-lamp exam, and corneal tomography. We compared the change in best corrected visual acuity and maximum keratometry readings from clinical visits before ring implantation to the latest follow up. RESULTS: A total of 68 eyes for 53 patients were included. The mean duration of follow up was 53.87 (± 38.8) months, with a maximum duration of 153 months. We found a significant improvement in corrected and uncorrected visual acuity, keratometries and refraction during the follow up period. On correlation analysis, strong negative significant correlation was found between duration since surgery and change in uncorrected visual acuity (p = 0.03, ρ = 0.338) and mean keratometry values (p = 0.033, ρ = 0.296). At the latest follow up for majority of patients with more than 100 weeks of follow up (12 eyes), uncorrected visual acuity were equal to or worse than baseline. CONCLUSION: This study represents the largest follow up for ICRS implanted in keratoconus patients. Improvement of visual acuity following ICRS implantation can be expected in the first few years, after which, a decline occurring thereafter.

Prevalence of depression and anxiety among otolaryngology outpatients at Jordan University Hospital.

PURPOSE: To determine the prevalence of depression and anxiety among otolaryngology outpatients at Jordan University Hospital. METHODS: A cross-sectional observational study was conducted between January 2017 and February 2018. The sample included 1328 otolaryngology adult outpatients, who completed (PHQ-9) and (GAD-7) questionnaires for depression and anxiety. Sociodemographic and clinical data were recorded. RESULTS: Depression and anxiety prevalence rates were 36.1% and 22.9%. The significant risk factors found for them were: age range 30 to 50 years, female sex, divorced status, smoking, alcohol drinking, asthma, family history of psychiatric illness, chronic illnesses, negative life events, secondary education, unemployment, low income, globus pharyngeus, tinnitus, and dizziness. PRACTICE IMPLICATIONS: Healthcare providers should have the vigilance to suspect and treat these disorders to improve patients' symptoms and quality of life.
