PREVALENCE OF LATTICE DEGENERATION IN AXIAL MYOPIA
Lattice degeneration is an important predisposing factor for retinal detachment. A cross sectional study of221 patients and 405 eyes with axial myopia of 25mm (–3.oo diopters) or more, was conducted with anobjective to find out prevalence of lattice degeneration of the retina among them. Of 221 patients, 48 (21.7%)had the lattice degeneration consisting of 35 uniocular (72.9%) and 13 binocular patients (27.1%). Of 139males, 36 (25.89%) had lattice degeneration; of 82 females, 12 (14.63%) had lattice degeneration (RR=1.26;95%CI=1.03-1.55; p=0.049). Axial length was from 25mm to 35.77mm (mean=27.63mm, SD 1.98). Thegreatest prevalence of lattice degeneration.9% (16 of 73 eyes) was found in eyes with axial length of 26mmto 26.99 mm (-6.0D to –8.97.0D), and the least incidence was 8.6% (8 of 93 eyes) in eyes with axial length25mm to 25.99 mm (-3.0 D to –5.97.0 D). Over all prevalence of lattice degeneration was 15% (61 of 405eyes) of eye(s) with axial length of 25 mm (-3.0 D) or more. In the age groups below 40 years, the prevalenceof lattice degeneration was highest 85.24% (59 of 61 eyes). The lattice degeneration of retina is moreprevalent in males of age less than 40 years with moderate axial myopia.Key Words: Lattice degeneration, axial myopia, retinal detachment.
