| pubmed-article:8156719 | pubmed:abstractText | Four young unmarried women developed unilateral non-fluctuating blepharoptosis by wearing contact-lenses. Past and family histories were unremarkable. Blepharoptosis insidiously occurred within a few years after wearing lenses. Contralateral lid was quite normal. No abnormalities was observed in pupils, extraocular muscles, ocular positioning and other systems. So far recognized causes of blepharoptosis were ruled out through extensive clinical and laboratory observations. Improvement was insufficient even after wearing lenses off. Pathogenesis is probably due to repeated minor trauma to the levator palpebral muscle and its tendon secondary to frequent wearing on/off contact-lenses. | lld:pubmed |
