Abstract

Purpose: To assess demographic variables, age at diagnosis and clinical characteristics of KERATOCONUS patients.Materials & Methods: This prospective descriptive study was performed on 285 eyes of 150 patients with kercetoconus, at The Ophthalmology Department of Yazd between March 2004 and August 2005. The main outcome measures were demographic variables, age at diagnosis, disease severity on biomicroscopic signs and topography.Results: The study included 89 (59.3%) male and 51 (40.7%) female subjects. One hundred-thirty five subjects (94.7%) had bilateral KERATOCONUS. Mean age at presentation was 17.43±3.71 years. Positive family history was seen in 9.3% of the cases. Based on topography and keratometry values 7.7% of eyes had mild, 49.1% had moderate and 43.2% had severe KERATOCONUS. Eyes with severe KERATOCONUS presented at younger age (15.8±4.32 years) than moderate KERATOCONUS (19.25±3.85 years). Uncorrected visual acuity less than 20/40 was seen in 82.8% of the eyes. Six eyes (1.4%) presented with corneal hydrops and this early occurrence of hydrops indicates coexisting vernal keratoconjunctivitis. Fourty two patients (84 eyes, 28%) had associated vernal keratoconjunctivitis.Conclusion: The majority of keatoconic eyes in Yazd patients demonstrate severe stages of the disease by the second decade.
