ABSTRACT
Los quistes epiteliales del iris o de cámara anterior son una rara y grave complicación tras la cirugía o traumatismos penetrantes del segmento anterior del ojo. Son secundarios a la invasión epitelial de la cámara anterior. Se ha descrito una incidencia de 0,09-0,12 por ciento, aunque estudios histopatológicos en ojos enucleados, tras cirugía de cataratas señalan una incidencia del 16 por ciento. Frecuentemente evolucionan hacia un aumento progresivo de tamaño y la producción de complicaciones visuales como glaucoma (de ángulo abierto por liberación de contenido mucoso del quiste, o cerrado), uveítis, descompensación corneal y membranas retrocorneales. Se presenta el caso de un paciente masculino de 61 años de edad, que acude a consulta tras una cirugía de dos meses de evolución, en la que se le realizó una cirugía combinada de catarata y glaucoma Al examen en lámpara de hendidura le son detectados varios quistes retroiridianos(AU)
Iris epithelial or anterior chamber cysts are a rare and serious complication following surgery or penetrating trauma to the anterior segment of the eye. They are secondary to epithelial invasion of the anterior chamber. An incidence of 0.09-0.12 percent has been described, although histopathological studies in enucleated eyes after cataract surgery indicate an incidence of 16 percent. They frequently evolve towards a progressive increase in size and the production of visual complications such as glaucoma (open angle due to the release of mucous content of the cyst, or closed), uveitis, corneal decompensation and retrocorneal membranes. We present the case of a 61-year-old male patient, who came to the clinic after a two-month surgery, in which he underwent a combined cataract and glaucoma surgery(AU)

Objective To evaluate the efficacy and safety of modified intracystic ethanol irrigation for traumatic iris cyst eyes.Methods A retrospective analysis was designed.Twelve cases of traumatic iris cyst patients were observed from August 2016 to August 2018 in Xiamen Eye Centre of Xiamen University.After anterior chamber filled with DisCoVisc,cyst fluid was drained gently via a 30-gauge needle,and ethanol was irrigated into the cyst through 3-way T-extension until the cyst wall turned white.DisCoVisc was washed in the end.Patients were followed for cornea and anterior chamber condition,best-corrected visual acuity (BCVA),intraocular pressure (IOP) and endothelial cell density (ECD).The diameters of maximal length and width in maximal cross-sectional area were calculated by ultrasound biomicroscopy (UBM) preoperatively and postoperatively.The follow-up period was 3 to 24 months.Written informed consent was obtained from each patient before surgery.Results BCVA (LogMAR) and IOP had no significant changes after surgery in one week (t=1.30,P=0.22;t=-0.91,P=0.38).BCVA was elevated in 5 cases at the last follow-up,but declined in 3 cases,kept stable in 4 cases.Mean intensity of ECD before and 3 months after operation was (2 270.79±458.43)/mm2 and (2 111.52±483.46)/mm2,respectively,the mean loss of ECD was 159.27 cells/mm2,and there was a significant change between the two time points (t=3.76,P=0.00).Mean postoperative maximal length diameter before and 3 months after operation was (5.87±0.95)mm and (1.46±0.83) mm,mean postoperative maximal width diameter was (3.10 ±0.55) mm and (0.89 ±0.47) mm,respectively,the mean postoperative maximal length diameter was reduced by 5.33 mm,and the mean postoperative maximal width diameter was reduced by 2.22 mm,with significant changes between the two time points (t =18.55,P =0.00;t =11.75,P =0.00).All cysts were resolved and without recurrence at the last follow-up.No significant complications,such as cornea endothelial decompensation,endophthalmitis,sympathetic ophthalmia and retinal detachment were seen during the follow-up period.Conclusions Modified intracystic ethanol irrigation is a safe and effective procedure to treat traumatic iris cysts,which is more simple with less injury and low rate of complications.
