Background:To compare intraocular pressure(IOP)changes following topical dexamethasone administration for 1 month in keratoconic versus normal eyes.Methods:This is a retrospective,single-center,non-randomized case series evaluation of 350 eyes.Two groups were formed:normal/control Group A(n_(A)=73),eyes that underwent excimer laser photorefractive keratectomy;and keratoconic(KCN)Group B(n_(B)=277),eyes that were subjected to partial laser photorefractive keratectomy combined with collagen cross-linking(The Athens Protocol).All eyes received the same post-operative regimen of topical dexamethasone 0.1%for at least 1 month.Goldmann applanation tonometry IOP readings and central corneal thickness(CCT)measurements were monitored.Cases with induced ocular hypertension(OHT,defined as post-operative IOP higher than 21 mmHg),were identified and correlated to refractive procedure,gender,and corneal thickness.Results:At 4 weeks postoperatively,OHT was noted on 27.4%(20/73 eyes)in Group A,and 43.7%(121/277 eyes)in KCN Group B,(p<0.01).Six months post-operatively(following 5-months of discontinuing topical dexamethasone treatment and commencing treatment of IOP-lowering medications),OHT rate was 1.8%in Group A and 3.9%in the KCN Group B.Conclusion:This study demonstrates a potentially significant pre-disposition of keratoconic eyes to the development of steroid-induced OHT. 展开更多
