Characteristics of eyes with phakic rhegmatogenous retinal detachment with single or multiple breaks

Purpose : To report the characteristics of eyes with phakic rhegmatogenous retinal detachment with single or multiple breaks. Cases and Method : This retrospective study was made on 98 eyes of 98 cases of rhegmatogenous retinal detachment. The series comprised 58 males and 40 females. All the cases were aged 50 years or over, received simultaneous cataract and vitreous surgery, and were measured for the volume of resected vitreous cavity. Results : There were 52 eyes with single retinal break and 46 eyes with multiple breaks. Out of 12 eyes with axial length of 23 mm or less, 11 eyes had single break. Out of 8 eyes with axial length of 27 mm or over, 5 eyes had multiple breaks. Out of 78 eyes with axial length between 23 mm and 27 mm, 38 eyes had single break and 40 eyes had multiple breaks. Corneal curvature radius and volume of vitreous cavity was significantly greater in eyes with multiple breaks than single break. There was no significant difference in axial length in eyes with multiple or single break between 23 mm and 27 mm. Conclusion : Axial length, vitreous volume, and cornel curvature radius are related with the number of retinal break in eyes with phakic retinal detachment.
