Comparison of the exposure rate of wrapped hydroxyapatite (Bio-Eye) versus unwrapped porous polyethylene (Medpor) orbital implants in enucleated patients.

Purpose: To compare the exposure rate of wrapped hydroxyapatite versus unwrapped porous polyethylene orbital implants in enucleated patients.

Methods: Medical records of the patients who underwent primary placement of hydroxyapatite (Bio-Eye) or porous polyethylene (Medpor) orbital implants after enucleation between 2002 and 2005 in Farabi Eye Hospital were reviewed, and the occurrence of implant exposure during follow-up visits was recorded. The exclusion criteria were secondary implantation, evisceration, or follow up of less than 1 year unless the exposure had occurred in the year after surgery.

Mersilene mesh versus sclera in wrapping hydroxyapatite orbital implants.

Purpose: To compare Mersilene mesh versus sclera in wrapping hydroxyapatite orbital implants used in primary enucleation.

Methods: In a prospective, randomized, interventional comparative case series, 60 eyes from 60 consecutive patients were included and randomly allocated for primary enucleation and either Mersilene mesh-wrapped hydroxyapatite (MHA) orbital implant (30 cases, 50%) or sclera-wrapped hydroxyapatite (SHA) orbital implant (30 cases, 50%) under general anesthesia. Complete socket examination was performed at 1 week, 1 month, and then every 3 months after surgery.

Initial nasolacrimal duct probing in children under age 5: cure rate and factors affecting success.

Aims: To evaluate the success rate of initial probing and the factors affecting the success rate for congenital nasolacrimal duct obstruction (CNLDO)in children under the age of 5 years.

Methods: In a prospective uncontrolled interventional case series, 207 eyes from 161 consecutive patients with CNLDO underwent nasolacrimal duct probing under brief general anesthesia. Based on exclusion criteria, 180 eyes from 139 patients were included in the study.
