Comparative and Prospective Study of Kerato-Allergic Conjunctivitis Associated with Keratoconus

 

Introduction: Chronic ocular friction during allergic keratoconjunctivitis in particular vernals could be one of the most important environmental factors that lead to development of keratoconus on genetically predisposed sites, severity and progression of keratoconus has been reported in these patients as well as earlier surgery. The main goal of our work is to conduct a comparative and prospective study between allergic keratoconjunctivitis associated with keratoconus on a series of 60 patients followed at the Ophthalmology B department of the Rabat Specialty Hospital. Materials and Methods: Our comparative and prospective study focused on 120 eyes of 60 patients with keratoconus associated with allergic peranual conjunctivitis or a vernal keratoconjunctivitis versus a control group presenting a keratoconus without ocular allergy, consultant of their own for a decrease in visual acuity or symptoms related to their allergic conjunctivitis, keratoconus have been confirmed by the realization of a corneal topography and followed in the Ophthalmology B department at Rabat Speciality Hospital over a period of 24 months ranging from September 2016 to August 2018.

 

Results: Our study has highlighted the role of allergic keratoconjunctivitis on the progression and severity of Keratoconus in particular during KCV with more advanced and severe Keratoconus. Indeed, in our study, in patients with vernal keratoconjunctivitis we find a predominance of the male sex in younger subjects with a mean age of our patients with this association of 12 years with respectively 07 and 05 years younger than those who had an allergy-free Keratoconus and those with the combination perenual allergic conjunctivitis and keratoconus. KCVs also had more severe keratoconus, depending on the median of spherical equivalent which was significantly higher in group B (Vernal Keratoconjunctivitis and Keratoconus) than the other 02 groups, Moreover there was no significant difference in the value of the cylinder according to the groups, the better corrected visual acuity was significantly lower, corneal thickness thinner central and higher IOP frequency in group B compared to group A and C. The values of keratometry were significantly higher in the group B compared to groups A and C with a proportion of 62.5% of stage Keratoconus 4 according to Amsler Krumeich’s classification for group B, compared to the group A and C with respectively 19.3% and 18.2% of stage 4.

 

Conclusion: The association between different forms of ocular allergy and the Keratoconus have been frequently found in recent years by many authors. In our study, grade 4 keratoconus was found significantly more important in the KCV than in the other 02 groups. Our study has highlighted the role of allergic conjunctivitis Peranuelle and Vernal Keratoconjunctivitis on the progression and severity of Keratoconus especially during the KCV with Keratoconus more evolved and more severe than this with regard to the visual acuity of the patients, their keratometric values, the weak central corneal thickness that sometimes prevents the achievement of physical therapy such as cross-linking and finally high IOP values mostly secondary to uncontrolled and abusive use of local corticosteroid therapy in these patients. It is crucial to explain to patients with a risk the importance of no longer rubbing their eyes. This simple prescription could have the potential to decrease the incidence of this pathology and slow down its progression alone or in combination with other therapies that have shown their effectiveness in recent years as the reticulation of corneal collagen.
