BACKGROUND: To present our experience on orbital and periorbital tissue changes after proton beam radiation therapy (PBRT) in patients with intraocular tumors, apart from treatment outcomes and disease control. METHODS: Medical records of 6 patients with intraocular tumors who had been treated with PBRT and referred to oculoplasty clinics of two medical centers (Seoul National University Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center) from October 2007 to September 2014 were retrospectively reviewed. The types of adverse effects associated with PBRT, their management, and progression were analyzed. In anophthalmic patients who eventually underwent enucleation after PBRT due to disease progression, orbital volume (OV) was assessed from magnetic resonance (MR) images using the Pinnacle3 program. RESULTS: Among the six patients with PBRT history, three had uveal melanoma, and three children had retinoblastoma. Two eyes were treated with PBRT only, while the other four eyes ultimately underwent enucleation. Two eyes with PBRT only suffered from radiation dermatitis and intractable epiphora due to canaliculitis or punctal obstruction. All four anophthalmic patients showed severe enophthalmic features with periorbital hollowness. OV analysis showed that the difference between both orbits was less than 0.1 cm before enucleation, but increased to more than 2 cm3 after enucleation. CONCLUSION: PBRT for intraocular tumors can induce various orbital and periorbital tissue changes. More specifically, when enucleation is performed after PBRT due to disease progression, significant enophthalmos and OV decrease can develop and can cause poor facial cosmesis as treatment sequelae.

PURPOSE: Choristomas represent congenital overgrowth of normal tissues in an abnormal location. The simultaneous presence of epibulbar choristoma and microphthalmos has rarely been reported. The authors report a case of extensive epibulbar choristoma associated with microphthalmos. CASE SUMMARY: A 9-day-old boy with the left eyeball absent from birth was referred to our clinic. A large cornea-like structure covered by keratinized membrane was observed inside the eyelid aperture, therefore buphthalmos or corneal staphyloma with microphthalmos was presumed. At the age of 2 months, a large mass of central conjunctival sac protruded through the left eyelid aperture. Manual reduction could not return the tissue to its original site and the mass immediately protruded again. At the age of 9 months, orbital magnetic resonance imaging showed the small presumed ocular tissue behind the large mass of fat signal in the central anterior orbit, therefore, extensive epibulbar choristoma associated with microphthalmos was diagnosed. At 12 months of age, partial excision of the protruding portion of the mass was performed. Based on pathologic examination, the mass was determined to be a choristoma and cosmetically acceptable appearance with prosthesis was maintained for 10 months after the surgery. CONCLUSIONS: Because there is no vision in extensive choristoma associated with microphthalmos, the treatment goal is cosmetic improvement. Conjunctivoplasty following partial mass excision for prosthesis wearing is a good treatment option.

PURPOSE: To analyze the features of lacrimal drainage system obstruction confirmed during external dacryocystorhinostomy surgeries and report the surgical outcomes. METHODS: We reviewed the medical records of a total of 769 cases who underwent external dacryocystorhinostomy for primary lacrimal drainage obstruction between 2005 and 2014. Data about detailed location and extent of obstruction were collected intraoperatively. The sites of obstruction were classified into nasolacrimal duct obstruction (NLDO), common canalicular obstruction (CCO), and canalicular obstruction. Lacrimal sac mucosa and lumen were grossly inspected, and the frequency of lacrimal sac changes, such as significant inflammation or fibrosis, was analyzed in cases of CCO or canalicular obstruction. The surgical success rate was also evaluated including effect of lacrimal sac status in the CCO and canalicular obstruction groups. RESULTS: Of 769 cases, primary NLDO with patent canaliculi was diagnosed intraoperatively in 432 cases (56.2%), CCO in 253 (32.9%), and canalicular obstruction in 84 (10.9%). Of 253 cases with CCO, 122 (48.2%) showed clear lacrimal sac lumen, and the other 131 (51.8%) showed significant inflammation or fibrosis of the lacrimal sac. In cases with canalicular obstruction, 35 of 84 (41.7%) showed a clear lacrimal sac, and the other 49 cases (58.3%) cases revealed mucosal changes of the lacrimal sac. The functional success rate was 87.5% for primary NLDO, 75.5% for CCO, and 72.6% for canalicular obstruction. In the CCO group, the functional success rate was lower in cases with significant lacrimal sac change (p = 0.044). CONCLUSIONS: Even in patients with CCO or canalicular obstruction, a large number of cases have lacrimal sac changes, and those changes were associated with lower functional success rate.
