Purpose: This study aimed to evaluate changes in optical quality after pterygium excision. Methods: We retrospectively reviewed the medical records of 14 patients (14 eyes) who had undergone pterygium excision using a limbal conjunctival autograft. All participants underwent the best-corrected visual acuity (BCVA) test, corneal topography, and Optical Quality Analysis System (OQAS) test preoperatively and 1 month postoperatively. The changes in these parameters associated with surgery were analyzed. Results: The participants were 10 men (10 eyes) and four women (four eyes), with a mean age of 61.6 years. There was no significant difference in the BCVA preoperatively and 1 month postoperatively. Corneal topography revealed significantly reduced astigmatism and OQAS showed that the modulation transfer function (MTF) cutoff value and Strehl ratio significantly improved postoperatively. Pterygium-induced astigmatism was significantly associated with the objective scatter index, MTF cutoff value, and Strehl ratio. Conclusions Pterygium excision may result in improved optical quality, suggesting that pterygia can decrease optical quality. A greater degree of pterygium-induced astigmatism may be associated with a more severe impairment of optical quality.

Hypercalcemia is not common, and occurs more frequently in children than in adults. Left untreated, hypercalcemia could result in a profound impact on growth and development. We report a case of recurrent idiopathic infantile hypercalcemia with poor weight gain, constipation, and a renal stone. We successfully treated the infantile hypercalcemia with a low-calcium diet and intravenous pamidronate.

Colonic angiosarcoma is an extremely rare and aggressive malignant tumor with poor prognosis. We report a case of colonic epithelioid angiosarcoma with colonic obstruction and rapidly progressive hepatic metastasis in a 44-year-old female. Abdominal CT revealed a heterogeneously enhancing irregular mass in the ascending colon, causing proximal bowel distension. The patient underwent surgery, and histopathological examination revealed a poorly differentiated carcinoma. A follow-up liver dynamic MRI after 4 months revealed newly developed diffusely scattered numerous small nodules in both hepatic lobes with peripheral and nodular marked arterial hyperenhancement, raising the suspicion of hepatic angiosarcoma. A pathologic second opinion was obtained, and additional immunohistochemistry revealed colonic epithelioid angiosarcoma. The patient showed progressive hepatic metastasis on follow-up abdominal CT after 6 months and died 8 months after initial diagnosis. We describe an educational case of colonic angiosarcoma, a rare malignant tumor, with rapidly progressive hepatic metastasis that showed radiologic findings suggestive of angiosarcoma and enabled a re-diagnosis for proper treatment and prognosis prediction.
