Abstract Details


To study the progression of atopic patients who underwent a keratoplasty for keratoconus compared with non-atopic patients.


Ophtalmology department, Mohammed VI University Hospital, Marrakesh, Morocco


Patients were divided into two groups: a group A with associated atopic manifestations (asthma, allergic rhinitis, atopic dermatitis and ocular allergy) (N = 13) and a second group B with no atopic manifestations (N = 29). We compared the two groups for those variables: Age at diagnosis, Stage of Keratoconus, Best corrected visual acuity before transplant, Hydrops occurrence, Age at the graft, complications after transplantation, and better corrected visual acuity after keratoplasty.


The mean age at diagnosis of keratoconus was 21 years in group A versus 25 years in group B. Keratoconus was classified as bilateral stage IV in 95% in group A and 78% in group B. The best corrected visual acuity was less than 1 logMAR in 78% (group A) and 50% (group B) After transplantation: - In group A: rejection (1 eye), cataract (2eyes), hypertonia (2eyes) - In group B: rejection (2 eyes), cataract (3 eyes), hypertonia (2 eyes) The best visual acuity corrected after transplantation was greater than 0.3 logMAR in 61% against 65% (respectively A and B)


Studies on a bigger sample could help to better understand the role of atopy in the genesis, expression and evolution of corneal transplant complications on keratoconus
