Purpose: To describe a new technique for ocular volume augmentation at the time of evisceration in patients with phthisis bulbi and microphthalmos. Methods: A retrospective, interventional, noncomparative case series of all patients with phthisis bulbi and microphthalmos who underwent successful evisceration with equatorial sclerotomy. The medical records were reviewed for patient history, surgical method, and postoperative course. Results: Eighteen patients (16 with phthisis bulbi and 2 with microphthalmos) underwent evisceration with equatorial sclerotomy and placement of an orbital implant of 20 mm in 11 patients (61%), 18 mm in 6 patients (33%) and 16 mm in 1 patient. Complications encountered were implant exposure in one patient, fornix shortening and symblepharon in one patient, and enophthalmos in another. Conclusion: Equatorial sclerotomy could be a useful adjuvant technique for placement of a larger orbital implant at the time of evisceration in patients with phthisis bulbi and microphthalmos.
