Evaluation of risk factors for postoperative prolonged intubation in premature infants after cryotherapy for retinopathy of prematurity.

Objective: Premature infants are more prone to cardiorespiratory complications after surgery than term infants. Risk factors for postoperative apnea include post-conception age, gestational age, postnatal age, birth weight, history of respiratory distress syndrome, bronchopulmonary dysplasia, anemia, necrotizing enterocolitis, use of opioids or nondepolarizing muscle relaxants, aminophylline use, history of apnea, body weight at operation, and pre-existing disease. The aim of this study was to identify the most important factors associated with postoperative extubation and respiratory outcomes among premature infants undergoing cryotherapy for retinopathy of prematurity (ROP).

Pneumatic displacement of a dense submacular hemorrhage with or without tissue plasminogen activator.

Background: To evaluate the efficacy of treating a dense submacular hemorrhage with pneumatic displacement with or without tissue plasminogen activator (tPA).

Methods: Twenty-four patients with a dense submacular hemorrhage were treated with intravitreal expansile gas, with or without an intravitreal injection of tPA, in order to displace the submacular blood. The main outcome measurements include preoperative and postoperative visual acuity, postoperative fluorescein angiography (FAG) results and additional postoperative treatments.

Visual results and complications after trans pars plana vitrectomy and lensectomy for lens dislocation.

Background: The aim of this study is to determine the relationship between the cause of lens dislocation and visual outcomes with complications in patients undergoing trans pars plana vitrectomy (TPPV) and trans pars plana lensectomy (TPPL) for lens dislocation.

Methods: This retrospective study was carried out from July 1995 through November 2003. After excluding patients with previous retinal detachment or combing lens dislocation and post-TPPV/TPPL follow-up intervals of less than 6 months, 36 eyes from 36 patients who had undergone vitrectomy and lensectomy for lens subluxation or dislocation due to trauma or intraocular surgery were examined.
