Topographic corneal changes in patients with vernal keratoconjunctivitis

Abstract

Results of this study suggested high frequency of patients with keratoconus associated with vernal keratoconjunctivitis. Visual performance is compromised by aberrations and changes in corneal asphericity and other topographic variables.

Topographic corneal changes in children with vernal keratoconjunctivitis: A report from Kathmandu, Nepal

“…VKC often presents as a relatively benign and self limited condition, disabling lesion such as corneal ectasia have been reported descriptively as a complication of severe and prolonged VKC [7,8]. Chronic ocular trauma and rubbing of eye due to pruritus could be the environmental factor ("trigger") associated with keratoconus development in genetically predisposed individuals [7].…”

Corneal Topographic Changes in Children With Vernal Keratoconjunctivitis: Tertiary Hospital Report From Jammu and Kashmir, India

“…(11)(12)(13)(14)(15)(16) All studies reported late presentation of keratoconus in VKC patients except Gortzak et al (15) Dantas et al report, palpebral VKC (97.81%) was more common in patients having keratoconus whereas mixed VKC (36.50%) was more common in our study. (17) Sixty four (30.47%) were found to have suspected keratoconus-like topography as compared to 10.7% by clinical criteria in our study. Slit lamp confirmed cases account for 10 of the 30 cases.…”

“…(15) Dantas et al reported 22.53% of keratoconus by videokeratographic maps and 9.85% clinically by slit lamp examination in VKC patients. (17) Total et al detected 26.8% of keratoconus by videokeratography maps and 8.5% clinically by slit lamp examination in VKC. (14) These studies used the modified Rabinowitz-McDonnell criteria.…”

“…(14) These studies used the modified Rabinowitz-McDonnell criteria. (15)(16)(17) whereas, we used pathfinder II corneal analysis using machine Carl zeiss meditec inc USA model ATLAS 9000 specially sensitive to early detection of keratoconus. Pathfinder II corneal analysis has sensitivity and specificity of >90% to detect abnormal corneas as reported by preliminary report in large multicentric clinical trials.…”

Características clínicas e imunológicas de pacientes com ceratocone e alergia ocular: um estudo transversal com ênfase na análise da inflamação da superfície ocular

“…Nas conjuntivites alérgicas, a presença de síndrome do olho seco e ceratocone têm sido descritas, bem como tem sido observada a evolução mais precoce de ceratocone em pacientes com CCV 4,20,46 . Da mesma forma, o uso exagerado de aparelhos eletrônicos, tem sido implicado como fator associado ao crescente número de pessoas com síndrome do olho seco, e por conseguinte deve ser considerado fator agravante das síndromes alérgicas 47,48 .…”
