Purpose: To find the prevalence of lattice degeneration in the various degrees of myopia and to assess its relation with respect to gender, age, location on retina and the presence of other peripheral Retinal lesions. Materials And Methods: The study was done in 300 eyes of 154 patients with myopia more than 1 dioptre. Patients with myopia <1D and those with history of optic nerve disease and past history of any surgery to the eye were excluded from the study. All patients included in the study were divided into 2 groups according to their refractive error as high myopic (>6D) and low myopic (<6D) groups. All patients underwent a complete ophthalmologic examination including refractive error assessment, indirect ophthalmoscopy as part of their routine clinical workup. Statistical calculations were performed using statistical software (SPSS version 16.0). Results: The prevalence of lattice degeneration was found to be 11.33%. Prevalence of lattice degeneration in myopia <6D was 6.25% and those of 6D or more was 20.37%. 135 eyes of 71 people of age group <20 years showed prevalence of 6.7%. Prevalence of lattice degeneration in age group 20-40 years was 16.15% and age group >40 years was 11.42%. Lattice degeneration associated with holes showed a prevalence of 12% and those with white without pressure (WWOP) showed prevalence of 38.2%. Isolated Lattice degeneration was prevalent in 50%. 131 eyes of 68 males showed a prevalence of 10% and 169 eyes of 87 females showed 12.4%. 56% of lattice was prevalent in superotemporal quadrant and 35.2% was prevalent in inferotemporal quadrant. Lattice degeneration was uniocular in 53% and binocular in 47.5%. Conclusion: Lattice degeneration was more prevalent in refractive error >6D.Age group of 2040 years showed more prevalence for lattice degeneration. Lattice associated with WWOP was found to be more prevalent than lattice associated with holes and other peripheral lesions. Lattice was found to be more common in superotemporal quadrant and was slightly more prevalent among females.
