The Clinical Aspect of Breaks Responsible for Retinal Derachment Associated with Lattice Degeneration

ABSTRACT

This study was undertaken to evaluate the retinal detachment related to lattice egeneration. We reviewed 54 eyes of 54 patients who had undergone retinal reattachment procedure from May 1992 to May 1995 at Yeungnam university hospital. Forty cases (74%) were due to atrophic holes in the lattice degeneration and 14 cases (26%) were due to tears at the lateral or posterior margin of lattice degeneration. Among 40 patients with atrophic hole, 25 patients (62.5%) were under 30-year-old and 26 patients (70.2%) were myopic over -3.0D. Among 14 patients with marginal tear, 9 patients (64.2%) were over 50-year-old and 8 patients had a refractive error of under -3.0D. Lattice degenerations were located most frequently in the temporal quadrants (46 cases, 85%). Retinal detachment related to lattice degeneration occurred in 30 eyes (56%) at superior retina, 20 eyes (37%) at inferior retina, 4 eyes (7%) at total retina, and had a much less serious prognosis in cases of atrophic hole compared with tear due to macula was less frequently involved in atrophic hole.
