Objective: This study aims to determine recurrence and complication rates among patients who underwent three current pterygium treatment techniques: preoperative subpterygeal injection of mitomycin C, intraoperative application of mitomycin with pterygium excision and pterygium excision with conjunctival autograft. Methods: This is a randomized controlled clinical trial in a tertiary hospital. We included patients with diagnosed primary pterygium and who underwent either: A = pre-operative injection of 0.02% mitomycin C one month prior to pterygium excision; B = pterygium excision with intraoperative mitomycin C application; or C = pterygium excision with conjunctival autograft. Results: We included 111 patients: a total of 120 eyes randomized to 3 groups (A, B, C) at 40 eyes per group. After 24 months of follow-up, there was no significant difference in the recurrence rates among the groups (6/40 [15%] in groups A and B and 2/40 cases [5%] in group C; P=0.29). No complications were noted in groups B and C, while 1 case of scleral thinning was noted in group A. There was no significant difference in the complication rates among the three procedures (P=1.00). Conclusion There were no significant differences in the recurrence and complication rates among the three techniques. Careful patient selection and follow-up are recommended to prevent complications such as scleral thinning.

Immunoglobulin G4 (IgG4)–related diseases are a spectrum of systemic inflammatory conditions of unknown etiology, which are characterized by infiltration of tissues by IgG4 plasma cells and sclerosing inflammation (Cheuk and Chan Adv Anat Pathol 17:303-32, 2010). Although this condition was initially described in relation to autoimmune pancreatitis, now it has been reported in almost every organ system of body (Zen and Nakanuma Am J Surg Pathol 34:1812-9, 2010, Masaki et al. Ann Rheuma Dis 68:1310-5, 2009). Orbital involvement by IgG4 disease can involve extraocular muscles (EOM), lacrimal glands, conjunctiva, eyelids, infraorbital nerve, orbital fat, and nasolacrimal system (McNab and McKelvie. Ophthal Plast Reconstr Surg 31:167-78, 2015, Katsura et al. Neuroradiology 54:873-82, 2012). The basis of using ⁶⁸Ga-DOTANOC PET/CT in IgG4 orbital disease is the known expression of somatostatin receptors in chronic inflammatory cells (Cuccurullo et al. Indian J Radiol Imaging 27:509-16, 2017) and also avidity shown previously in other IgG4-related diseases (Cheng et al. Clin Nucl Med 43:773-6, 2018).

PURPOSE: To report a patient stung by a bee, who was diagnosed with sterile endopthalmitis and another patient diagnosed with optic neuritis, with decreasing visual acuity, after refined bee venom injection around the orbital tissue. CASE SUMMARY: A 82-year-old female visited our hospital for decreased visual acuity in the right eye and ocular pain due to a bee sting. The bee sting penetrated the sclera into the vitreous. In the anterior segment, severe cornea edema and anterior chamber cells were seen. Using ultrasonography, inflammation was seen around the intravitreal area. After 3 months, intravitreal inflammation regressed but the patient's visual acuity was light perception negative, and corneal opacity, neovascularization, and phthisis bulbi were detected. A 55-year-old male visited our hospital for ocular pain in the right eye and decreasing visual acuity after refined bee venom injection around the orbital tissue. The best-corrected visual acuity in the right eye was 15/100, there was moderate injection on the conjunctiva. A relative afferent pupillary defect, abnormal color vision test results, and a defect in the visual field test were observed. There was no pain during external ocular movement, and other general blood tests, and a brain MRI were normal. Based on these symptoms, methylprednisolone megatherapy was started for treatment of optic neuritis. After treatment, visual acuity of the right eye was 9/10 and all other clinical optic neuritis symptoms regressed. CONCLUSIONS: Based on these two cases, ocular toxicity from bee venom could result from both direct and indirect courses. Treatment using refined bee venom might be harmful, and caution is recommended in its use.

PURPOSE: When there is a mass in the superior temporal orbit area, a lacrimal gland tumor should be suspected. We report a rare case of orbital lymphatic malformation that was histologically diagnosed in a patient with typical clinical features of the lacrimal gland. CASE SUMMARY: A 55-year-old female with no underlying disease and no ophthalmic history visited our clinic with a right upper eyelid edema associated with an enlarged painless eyelid mass 1 month prior to her visit. The patient stated that she discovered the mass 1 year previously.The palpebral lobe of the lacrimal gland protruded slightly with congestion of the surrounding conjunctiva. Enhanced computed tomography showed a 3 cm well-defined heterogeneous mass in the right lacrimal gland area and several well-defined round calcifications within the mass. Orbital tissue or bone involvement was not observed. The pleomorphic adenoma of the lacrimal gland was the most clinically suspicious, so complete resection of the mass was performed using lateral orbitotomy. Histopathologically, lymphangioma (lymphatic malformation) originating from the lacrimal gland was diagnosed. CONCLUSIONS: Orbital lymphatic malformation can occur in the lacrimal gland. The present case showed that differential diagnosis can reveal the presence of an adult lacrimal gland tumor.

An 8-year-old Shih Tzu, a 5-year-old Maltese, and a 10-year-old Maltese presented with conjunctival hyperemia and peripheral corneal edema. Severe conjunctival thickening with varying degrees of corneal extension was observed. Cytological examination showed many large lymphocytes with malignant changes in the conjunctiva which was consistent with findings in fine-needle aspiration samples taken from regional lymph nodes. They were diagnosed as having Stage V multicentric lymphoma. When conjunctival thickening is observed in canine patients with multicentric lymphoma, conjunctival metastasis with infiltration of neoplastic lymphoid cells should be included in the differential diagnosis.

The purpose of this study is to discuss several approaches to addressing naso-orbito-ethmoidal (NOE) fracture. Orbital fracture, especially infraorbital fracture, can be treated through the transconjunctival approach easily. However, in more severe cases, for example, fracture extending to the medial orbital wall or zygomatico-frontal suture line, only transconjunctival incision is insufficient to secure good surgical field. And, it also has risk of tearing the conjunctiva, which could injure the lacrimal duct. Also, in most complex types of facial fracture such as NOE fracture or panfacial fracture, destruction of the structure often occurs, for example, trap-door deformity; a fracture of orbital floor where the inferiorly displaced blowout facture recoils to its original position, or vertical folding deformity; fractured fragments are displaced under the other fragments, causing multiple-packed layers of bone.

Intraorbital infection shows a low incidence, but it might cause blindness or even death. This case is unusual in that its origin from a craniofacial bone fracture prior to infection of the maxillary sinus. A 33-year-old female patient was referred for right cheek swelling. When she visited the emergency room, we removed right cheek hematoma and bacterial examination was done. In the past, she had craniofacial bone surgical history due to a traffic accident 6 years ago. Next day, the swelling had remained with proptosis and pus was recognized in the conjunctiva. We planned an emergency operation and removed the pus which was already spread inside the orbit. And the evaluation for sinusitis was consulted to the otorhinolaryngology department simultaneously. There were Prevotella oralis and methicillin-resistant Staphylococcus epidermidis bacterial infection in the intraorbital and sinus respectively. Afterwards, the vigorous dressing was done for over a month with intravenous antibiotics. Though the intraorbital infection was resolved, blindness and extraocular movement limitation were inevitable. In conclusion, close follow up of the maxillary sinus in facial bone fracture patients is important and aggressive treatment is needed when an infection is diagnosed.

PURPOSE: To report a case of primary amyloidosis localized to the conjunctiva. CASE SUMMARY: A 19-year-old male with a conjunctival mass and foreign body sensations in the right eye transferred from another hospital. A 0.5 × 2.5 cm reddish mass was present in the medial canthus of the right conjunctiva with no other clinically specific signs. Surgical excisional biopsy was performed. Histological examination showed amyloid deposition. There was no other orbital involvement apart from the conjunctiva. Abnormalities were not found in the systemic examination. CONCLUSIONS: We report a case of primary amyloidosis localized to the conjunctiva.

PURPOSE: To report a case of a Corynebacterium macginleyi-infected corneal ulcer of a patient who had been treated for conjunctivitis for more than 3 months. CASE SUMMARY: A 72-year-old female was transferred from a private ophthalmic clinic for evaluation of herpetic keratitis with progressive corneal edema and infiltration in the left eye. She had a history of conjunctival hyperemia and eyeball pain in her left eye 3 months prior to her visit. She was treated with levofloxacin eye drops and acyclovir ointment (Herpesid®, Samil, Co., Ltd. Seoul, Korea). On slit lamp examination, 5.4 × 4.0 mm corneal epithelial defects and stromal infiltrations were observed in the upper to central cornea, and endothelial keratic precipitates were found. Gram positive bacteria were detected on Gram staining and Corynebacterium macginleyi was identified on bacterial cultures from the conjunctiva and cornea. She was treated with topical vancomycin eye drops. After 3 months of treatment, the corneal ulcer was completely resolved, leaving mild superficial opacity on the cornea. CONCLUSIONS: While Corynebacterium macginleyi, normal flora of the conjunctiva, is considered a major causative agent for conjunctivitis and blepharitis, Corynebacterium macginleyi should also be considered a possible cause of slowly progressive keratitis in patients with chronic conjunctivitis.
