At times it is difficult to distinguish among the subtypes of chronic allergic conjunctivitis. A prospective study with 134 patients was carried out. Patients were diagnosed with vernal keratoconjunctivitis (VKC), atopic keratoconjunctivitis (AKC) or perennial allergic conjunctivitis (PAC). Demographic information was also collected including, age at symptom onset, sex, history of non-ocular allergy, and history of family allergy. Forty-six percent were diagnosed with VKC, 40% with AKC, 8% with PAC, and 6% were not specifically diagnosed. This distribution information as well as the demographic information collected demonstrates that there are patterns within each subgroup of chronic ocular allergy sufferers. These findings will be helpful in the diagnosing and proper classification of ocular allergic conditions.
有时很难区分慢性过敏性结膜炎的亚型。对134例患者进行了一项前瞻性研究。患者被诊断为春季角结膜炎（VKC）、特应性角结膜炎（AKC）或常年性过敏性结膜炎（PAC）。还收集了人口统计学信息，包括症状出现时的年龄、性别、非眼部过敏史和家族过敏史。46%被诊断为VKC，40%为AKC，8%为PAC，6%未明确诊断。这些分布信息以及收集到的人口统计学信息表明，慢性眼部过敏患者的每个亚组中都存在一些模式。这些发现将有助于眼部过敏疾病的诊断和正确分类。
