To compare the outcome of collagen cross linking in patients who were less than 18 years of age to those who were more than 18 years of age.
Maxivision Eye Hospital, Hyderabad
We retrospectively reviewed all the files of patients who underwent CXL for Keratoconus between June 2011 to June 2012. The patients were divided into 2 groups for analysis. The group 1 included patients under 18 yrs of age and group 2 more than 18 years of age. All these patients had a standard procedure using Dresden protocol with regular Riboflavin. Best spectacle corrected visual acuity(BSCVA), manifest refraction, orbscan changes and clinical picture were recorded before surgery and at 6 months.
The group 1 included 14 eyes of 10 patients ( 5 males and 5 females) with an mean age of 14.1 years( range 10 17 yrs) and group 2 included 13 eyes of 12 patients ( 6 males and 6 females) with an average age of 20.4 years ( range 18 27 yrs).There was significant improvement of BSCVA from a preoperative mean of 0.25 ( 0.00 to 0.30) to 0.14 ( 0.00 to 0.30) post operatively in group 1, whereas in group 2 there was no significant change in the BSCVA from a preoperative mean of 0.18 ( 0.00 to 0.30) to 0.14 ( 0.00 to 0.30). There was 1.5 D of reduction in K value in the patients under 18 yrs of age versus 1D reduction in K value in patients more than 18 years of age. All eyes developed minimal faint stromal haze that cleared within 1 month. Progression of disease was not seen in any of the treated eyes within 6 months of follow up.
Riboflavin-UVA corneal cross-linking resulted in better post op BSCVA and more reduction of K value in patients younger than 18 years of age as compared to patients more than 18 years of age.
