ABSTRACT
@#AIM:To analyze the effects of corneoscleral limbus incision phacoemulsification and corneal incision phacoemulsification on postoperative rehabilitation of elderly cataract patients.<p>METHODS: Totally 98 elderly cataract patients(132 eyes)who underwent phacoemulsification in our hospital during the period from January 2015 to January 2017 were enrolled. According to surgical incision sites, they were divided into corneoscleral limbus incision group(group A, <i>n</i>=52 cases, 74 eyes)and corneal incision group(group B, <i>n</i>=46 cases, 58 eyes). The changes of uncorrected visual acuity, best corrected visual acuity(BCVA)and corneal astigmatism in both groups were measured at different time points before and after operation. The epithelial repair time and incision repair time in both groups were statistically analyzed. The changes of tear break-up time(BUT), tear secretion and corneal staining score were recorded at different time points before and after treatment. The incidence of postoperative complications was statistically analyzed.<p>RESULTS: There were significant differences in uncorrected visual acuity, corneal astigmatism, surgery induced corneal astigmatism, BCVA, BUT, tear secretion and corneal staining scores between the two groups and within the same group at different time points(<i>P</i><0.05). The uncorrected visual acuity and BCVA in group A were superior than those in group B at different time points after operation. The corneal astigmatism and surgery induced corneal astigmatism were lower than those in group B. BUT was longer than that of group B. And tear secretion was higher than that in group, and corneal staining score was lower than that in group B(<i>P</i><0.05).The epithelial repair time and incision repair time in group A were shorter than those in group B after operation(<i>P</i><0.05).There was no significant difference in the incidence of postoperative complications between the two groups(<i>P</i>>0.05).<p>CONCLUSION:The phacoemulsification under corneoscleral limbus incision can improve postoperative visual acuity of elderly cataract patients, reduce the corneal astigmatism, reduce the influence on the tear film function, and promote postoperative rehabilitation.
ABSTRACT
A case of a juvenile xanthogranuloma of the corneoscleral limbus was encountered in a 5-year-old oriental boy, who presented with a 5-month history of a lump in the right eye. The lesion extended from the inferior limbus. This yellow-orange mass was vascular and firmly fixed to the underlying tissue. The lesion was diagnosed preoperatively as an atypical dermolipoma and an uneventful excisional biopsy was performed. The pathologic diagnosis showed the characteristic picture of a juvenile xanthogranuloma with numerous Touton giant cells. Dermoid and lipodermoid tumors, as a corneoscleral limbal mass, are the most frequently encountered in childhood. A juvenile xanthogranuloma is a rare and usually benign skin disease with an unknown cause, which occurs in infants and young children. However, it can occur also as a corneoscleral limbal mass in young children.

We describe a case of xanthoma on the corneoscleral limbus in a 21-year-old man. It was characterized by a localized, round, elevated, yellowish mass on the right superonasal limbus with 6mm in size. There was no correlation with systemic or metabolic diseases such as hyperlipidemia and the microscopic examination revealed scanty fibrous element.
