ABSTRACT

La vitrectomía pars plana en el desprendimiento de retina, así como la cirugía de patologías maculares y de la retinopatía diabética, entre otras, exacerba la progresión y el desarrollo de catarata en pacientes fáquicos, considerada una complicación frecuente de esta intervención. La extracción de catarata en ojos con cirugía vítrea previa se caracteriza por una serie de diferencias que particularizan a este tipo de pacientes. Esta particularidad motivó la siguiente revisión con el propósito de hacer referencia a algunos factores que influyen en el desarrollo o progresión de la catarata después de la vitrectomía pars plana, complicaciones de los sustitutos vítreos, opciones en la realización simultánea o secuencial de la cirugía de segmento anterior y posterior. Se aborda también algunas consideraciones pre y transoperatorias de la cirugía de catarata en ojos vitrectomizados, así como complicaciones trans y postoperatorias. La capacidad visual puede mejorar significativamente luego de la cirugía de catarata, sin embargo, la cuantía de la misma estará determinada por la extensión y severidad de la patología vítreo-retiniana de base


Pars plana vitrectomy in retinal detachment as well as in macular pathology and diabetic retinopathy surgeries, among others, exacerbated the progression and the development of cataract in phakic patients, which is considered a common complication of this intervention. Cataract extraction in eyes that underwent previous vitreous surgery is characterized by a series of differences that particularize this type of patients. This particularity encouraged the following review to mention some factors influencing the development or the progression of cataract after pars plana vitrectomy, complications of vitreous replacements, options in simultaneous or sequential performance of the anterior and posterior segment surgery. It also dealt with some preoperative and transoperative considerations of the cataract surgery in vitrectomized eyes as well as transoperative and postoperative complications. The visual capacity may significantly improve after the cataract surgery; however, the magnitude of such capacity will be determined by the extension and severity of the underlying vitreous-retinal pathology

ABSTRACT

Objetivo: determinar el comportamiento del endotelio corneal en pacientes sometidos a cirugías secuenciales de vítreo y catarata.Métodos: estudio observacional descriptivo, prospectivo en una muestra conformada por 15 ojos de 15 pacientes sometidos a cirugías múltiples del vítreo y del cristalino, entre enero y noviembre de 2010.Resultados: la mayoría de los pacientes fueron hombres entre 53 y 67 años. Las causas de indicación quirúrgica de vitrectomía pars plana fueron desprendimiento de retina y hemorragia vítrea. La densidad celular promedio preoperatoria y posoperatoria descendió el 17,2 por ciento. Predominó la ausencia de polimegatismo y sus formas leves en el preoperatorio, con un incremento de formas moderadas y severas en el posoperatorio. El pleomorfismo se comportó de una forma similar al polimegatismo. Las complicaciones posquirúrgicas fueron la hipertensión ocular, el síndrome tóxico de segmento anterior y la uveítis anterior, con 9 casos entre los dos momentos quirúrgicos. Conclusiones: el endotelio corneal sufre modificaciones, tanto anatómicas como funcionales luego de ser sometido a una vitrectomía pars plana, las que se acentúan luego de una segunda cirugía, más aún si esta es en el segmento anterior como la extracción de la catarata por facoemulsificación


Objective: to analyze the corneal endothelium behavior in patients undergoing sequential vitreous and cataract surgery. Methods: a prospective, descriptive and observational study of 15 patients (eyes) with several vitreous and lens surgeries at the "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from January through November 2010. Results: most of the patients were males whose ages ranged 53 to 67 years. The main causes for indicating pars plana vitrectomy were retinal detachment and vitreous hemorrhage. Pre and postoperative cellular density averages in this group showed a cellular loss of 17.2 percent. In the preoperative exam, lack of polymegatism in its mildest forms predominated, whereas moderate and severe forms increased in the postoperative phase. Pleomorfism behaved in a similar way. Postsurgical complications found were ocular hypertension, anterior segment toxic syndrome and anterior uveitis, with 9 cases at the two surgical periods. Conclusions: the corneal endothelium suffers both anatomical and functional changes after pars plana vitrectomy, which may be remarkable after a second surgery, even more if this occurs in the anterior segment such as the cataract extraction using phacoemulsification

ABSTRACT

PURPOSE: To evaluate the effectiveness and safety of combined phacoemulsification, pars plana vitrectomy and IOL implantation in non-diabetic patients, and to compare the clinical results with that of sequential surgery. METHODS: The results of combined phacoemulsification, pars plana vitrectomy and IOL implantation in 15 patients (15 eyes) were retrospectively analyzed. Major outcome measures were pre-and postoperative best-corrected visual acuity (BCVA), postoperative BCVA 0.5 or better, and postoperative complications. Comparison between the combined surgery in 12 eyes and sequential surgery in 9 eyes were also analyzed for the same outcome measures. RESULTS: Of the 15 eyes postoperative visual acuity improved in 14 eyes (93.3%), and BCVA 0.5 or better was achieved in 6 eyes (40.0%). Of the 15 eyes postoperative complications consisted of transient IOP increase in 8 eyes (53.3%), hyphema in 4 eyes (26.7%), retinal detachment in 3 eyes (20.0%), vitreous hemorrhage in 2 eyes (13.3%), anterior chamber fibrin exudation in 2 eyes (13.3) and posterior capsular rupture in 2 eyes (13.3%). The difference in complications between the combined surgery group and sequential surgery group were not statistically significant. CONCLUSION: Combined surgery in selected patients is a safe and effective approach, and the outcome is comparable to sequential surgery.
