RESUMO
Pneumatic retinopexy is a procedure which can be utilized as an alternative to scleral buckling to repair retinal detachment. It offers the advantages of being less invasive and is easily performed under local anesthesia on an outpatient basis. We enjoyed an initial success rate of reattachment in five of six eyes with this procedure. One case experienced late redetachment, and a subsequent case experienced early redetachment from development of new retinal breaks. Six cases were successfully reattached in one or two procedures, and all cases were reattached in three procedures. All patients experienced stable or improved vision with pneumatic retinopexy.

Complications of contact lens wear include limbal neovascularization, corneal edema, keratitis, and spectacle blur. The incidence of complications was studied in a population of new clinic patients previously fitted for contact lenses. Patients whose daily wear time was greater than 12 hours had a significantly greater incidence of complications. Factors that are presumed to contribute to this difference include hypoxic effects, mechanical trauma, and hygiene. Patient education is stressed for the treatment and prevention of contact lens related complications.

Digital fundus imaging was used for fluorescein angiography in patients with subretinal neovascularization. After laser treatment, digital red-free photographs were obtained and compared against pretreatment angiogram frames to determine the margins of treatment. This technique allowed instant review of images and confirmation of complete laser treatment of the lesions. Of 15 eyes treated and followed for at least one year, there were two eyes with early recurrences (13%). A total of five eyes had recurrences during the follow-up period (33%). Digital imaging is a useful tool for treating subretinal neovascularization.

Fluorescein angiographic images from digital and photographic systems were obtained simultaneously from consecutive patients and examined in a side-by-side manner for evaluation of graininess, contrast, focus, and overall image quality. Digital fundus images showed superior contrast and overall image quality compared with photographic images obtained in this manner. These images were rated as somewhat grainier than photographic images. Patients had fewer complications undergoing digital fluorescein angiography versus photographic fluorescein angiography. Digital fundus imaging is a legitimate alternative to photographic imaging and offers the potential advantage of fewer complications compared with photographic techniques.
