Four petals evisceration for atrophia bulbi.

Purpose: To study the use of four petals evisceration in atrophia bulbi to allow insertion of large orbital implant.

Materials And Methods: An interventional case series. All cases were atrophia bulbi. The axial lengths (AL) of atrophic and contralateral normal eye were measured. It was planned to use implant 3 mm smaller than AL of the contralateral normal eye. Four petals evisceration was used in all cases.

Results: Twenty cases were included. The mean age was 27.08 ± 16.07 years. The mean axial length (AL) of atrophic eyes was 16.97 ± 1.42 mm. In 75% of cases, the planned implant was inserted. In all cases, the implant diameter was larger than AL of atrophic eye by a mean of 2.57 ± 0.64 mm. The AL of atrophic eye did not affect the implant size. The mean follow-up period was 22.4 ± 10.1 months. Implant exposure was not recorded in any case. Volume deficiency was recorded in 2 cases (10%).

Conclusions: Four petals evisceration facilitated the use of suitable sized implant in atrophia bulbi with minimal complications.
