Abstract
Anterior Staphyloma is an ectasia of pseudocornea which results after sloughing of cornea with iris plastered behind. Our patient presented with
loss of vision, white corneal opacity & abnormal bulging of the right eye since childhood following penetrating ocular trauma by a wooden
stick.Patient had come to the hospital only to seek cosmetic improvement. Clinical diagnosis of Anterior Staphyloma was made. After informed
written consent patient was taken up for surgery and a Evisceration was performed under local anaesthesia by placing a silicone orbital implant
within the scleral pocket.Patient was sent for customised ocular prosthesis after 2 months of surgery. A customised ocular prosthesis over the
well formed sclero -conjunctival pocket can bring back some amount of movement with complete cosmetic recovery which apparently appears
normal, thus an ocular prosthesis should be provided as soon as possible for the psychological well being of the patient.
