Comparison of the effectiveness of pneumatic retinopexy between two main groups of patients. Patients with phakic and pseudophakic eyes respectively.
Ophthalmology Clinic, University Hospital of Ioannina
82 patients with rhegmatogenous retinal detachment participated in the study. All patients underwent pneumatic retinopexy in the University Ophthalmology clinic of Ioannina. 54 of the eyes were phakic and 28 were pseudophakic. Data collected on each patient included age, visual acuity before and after the procedure, macular status, number, position and extent of the tears, clock hour extent of the detachment, coexisting retinal degenerations and the possible presence of vitreous haemorrhage. After topical anesthesia cryopexy was performed on the area of the break. In addition, paracentesis of the anterior chamber that was followed by gas injection (C3F8 or SF6) through the pars plana into the vitreous cavity. Next day supplementary laser photopexy or cryopexy was performed.
The success of the method among patients with phakic eyes was 77.8% while for the patients with pseudophakic eyes the success rate was 42.9%. When pneumatic retinopexy failed (22.2% of phakic and 57.1 % of pseudophakic) the patient underwent vitrectomy for the treatment of retinal detachment.
The results show that the presence of the crystalline lens is positively associated with higher success rates of pneumatic retinopexy while other factors associated with the outcome are the duration of the detachment, the extend and position of the breaks as well as the extent of the detachment.
