PURPOSE: To report a patient with a pseudophakic bullous keratopathy (PBK) who underwent Descemet's membrane stripping endothelial keratoplasty (DSEK) with manual preparation of the donor corneal graft.CASE SUMMARY: A 61-year-old female presented with visual disturbance in her right eye. Five months prior, she was treated with phacoemulsification and intraocular lens exchange surgery of the right eye, and a very severe corneal edema was revealed by slit-lamp examination. We diagnosed PBK and planned DSEK with manual preparation of a donor corneal graft because of the non-availability of a microkeratome or a femtosecond laser. After making the corneal graft using an artificial anterior chamber, crescent knife and cornea dissector, the keratoplasty proceeded using the graft. Three months after surgery, her graft was well-maintained on the right eye. The patient's visual acuity was 0.3, and the corneal endothelial cell count was 1,844/mm².CONCLUSIONS: Manual preparation of the donor corneal graft for DSEK is suitable as a second choice treatment method when the availability of surgical devices is limited.

PURPOSE: To report a case of Epstein-Barr virus-related corneal endotheliitis accompanied by secondary glaucoma.CASE SUMMARY: A 73-year-old male presented with blurred vision in his right eye. In the ophthalmic evaluation, there were dispersed keratic precipitates overlying corneal edema. The anterior chamber showed trace ~1+ graded inflammation and an endothelial density decrease. His best-corrected visual acuity and intraocular pressure in the right eye were 0.2 and 34 mmHg, respectively. Paracentesis was performed on the anterior chamber of the right eye to confirm the diagnosis under the suspicion of corneal endotheliitis with trabeculectomy for the intraocular pressure control. Epstein-Barr virus was confirmed using a multiplex polymerase chain reaction (PCR), and oral and eye drops of Acyclovir were used to treat the patient. There was no evidence of a recurrence over 2 years and his intraocular pressure was 12 mmHg and best-corrected visual acuity was maintained at 0.5.CONCLUSIONS: A case of Epstein-Barr virus-related corneal endotheliitis was diagnosed using PCR of the aqueous humor. The patient was treated with an oral antiviral agent and eyedrops without a recurrence.

PURPOSE: To report two cases of postoperative endophthalmitis caused by Streptococcus dysgalactiae subspecies equisimilis (SDSE), which appeared as hyperacute presentation and panophthalmitis. CASE SUMMARY: A 68-year-old male was treated with cataract surgery and was evaluated the next day (less than 24 hours after surgery) because of acute loss of vision. There was severe inflammation and the visual acuity was light perception. The patient underwent pars plana vitrectomy (PPV) with intravitreal antibiotic injection. The vitreous culture revealed SDSE. After PPV, regression of inflammation was observed, although the corneal edema had progressed. The cornea evolved to decompensate due to bullous keratopathy and visual acuity of the eye decreased to no light perception after 3 months. A 87-year-old male who underwent phacoemulsification and intraocular lens implantation 2 days previously was hospitalized due to severe ocular pain and visual loss. There was severe inflammation, and the visual acuity was no light perception. The patient received only intravitreal injections of antibiotics due to severe corneal necrosis. The aqueous humor revealed SDSE. Four days after intravitreal injection, erythema and swelling of the eyelid of the affected eye was observed, and diagnosed as panophthalmitis. After treatment with intravenous antibiotics, cellulitis of the eyelid was resolved. The eye progressed as phthisis after 3 months without recurrence. CONCLUSIONS: Postoperative SDSE endophthalmitis showed aggressive and hyperacute presentation, resulting in blindness despite prompt treatment. SDSE is an emerging organism and should be considered a potential cause of postoperative endophthalmitis.

PURPOSE: We evaluated the short-term clinical outcomes of patients who underwent modified scleral fixation of an intraocular lens (IOL) using a scleral tunnel and groove. METHODS: From June 2016 to May 2017, 34 eyes of 34 patients who underwent modified scleral fixation of an IOL using a scleral tunnel and groove were retrospectively studied. We evaluated the best-corrected visual acuity (BCVA), corneal endothelial cell density, intraocular pressure (IOP), spherical equivalent, and postoperative complications at 1 week, 1 month, 3 months, and 6 months after surgery. RESULTS: The BCVA was 0.85 ± 0.83 logarithm of the minimal angle of resolution (logMAR) before surgery and 0.38 ± 0.61 logMAR at 6 months (p = 0.001). The corneal endothelial cell count was 1,955.12 ± 217/mm2 and 1,852.59 ± 190/mm2, before and after surgery, respectively, which was not significantly different (p = 0.186). Postoperative complications occurred in eight eyes (23.5%); IOP elevation in one eye (2.9%), IOL tilt or decentration in two eyes (5.7%), optic capture in four eyes (11.4%), and cystic macular edema in one eye (2.9%). The spherical equivalent showed myopic changes after surgery and decreased significantly over time (p = 0.001). CONCLUSIONS: Modified scleral fixation of the IOL using a scleral tunnel and groove improved the BCVA, but did not significantly affect corneal endothelial cell loss. This procedure can be a good alternative to conventional scleral fixation of an IOL, which has advantages in shortened surgical time and easy surgical manipulation.

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: To report a case of chemical injury of the cornea caused by high-dose ethanol during orbital wall fracture repair. CASE SUMMARY: A 56-year-old male presented with pain after blowout fracture repair surgery. During the surgery, 2% hexethanol solution (2% chlorhexidine and 72% ethanol mixture), which was used for disinfection of the face, flowed into the left eye. Conjunctival injection in the left limbus, a large corneal epithelial defect, and severe stromal edema were subsequently observed. The patient was treated with topical antibiotics, steroids, and autologous serum eye drops. After 1 week, the corneal epithelial defect was improved, but at the second month of therapy, recurrent corneal erosion with deterioration of the endothelial cell function occurred. Anterior stromal puncture and laser keratectomy were performed. The corneal epithelial defect and erosion improved, but the endothelial cell density was severely decreased. CONCLUSIONS: The 2% hexethanol solution is usually used for preoperative skin disinfection, but it contains a high concentration of ethanol. The surgeon should be aware that high concentrations of ethanol may result in severe corneal damage, including corneal endothelial dysfunction and limbal cell deficiency.

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.

A 10-year-old intact female Jindo dog was presented with a 1-week history of conjunctival redness and ocular discharge in the left eye. There was an absence of menace response, dazzle reflex, and direct pupillary light reflex. Slit-lamp biomicroscopy revealed corneal edema, ciliary flush, and aqueous flare. Intraocular pressure was 68 mmHg. Based on the information available, a diagnosis of glaucoma and uveitis was made. Subsequent histopathologic examination showed the glaucoma was produced by the effects of goniodysgenesis, posterior synechia, and pigment dispersion in the trabecular meshwork. This is the first report of primary glaucoma caused by goniodysgenesis in Jindo dogs.

PURPOSE: To report a case of anterior uveitis secondary to Listeria monocytogenes infection. CASE SUMMARY: A 57-year-old male presented to our clinic with ocular pain and decreased vision in the right eye for 2 days. The patient had a history of liver transplantation 2 years prior and used immunosuppressive agents. Listeria monocytogenes was identified in blood cultures 1 month before his visit. At presentation, best-corrected visual acuity (BCVA) of the right eye was counting fingers at 20 cm and the intraocular pressure (IOP) was 50 mmHg. Conjunctival hyperemia, corneal edema, keratic precipitates, and cells in the anterior chamber were observed in the right eye. The patient was diagnosed as anterior uveitis in the right eye. Conventional uveitis treatment was initiated but clinical features did not improve and black hypopyon appeared. The possibility of anterior uveitis caused by Listeria monocytogenes infection was considered. An anterior chamber tap and culture were conducted to identify pathogens. Anterior chamber antibiotic injections and systemic antibiotic injections were performed. One week after injection, the BCVA of the right eye improved to 0.4 and the IOP decreased to 14 mmHg. One month after injection, the BCVA of the right eye improved to 1.0 and the IOP decreased to 16 mmHg. No inflammation of the anterior chamber was observed. CONCLUSIONS: When nonspecific uveitis occurs in immunosuppressed patients, cultures and appropriate antibiotics should be considered because of the possibility of infection.

PURPOSE: To report a case of corneal edema caused by an iatrogenic lidocaine injection into the corneal stroma created while performing a local anesthetic (lidocaine) injection into the eyelid for a blepharoplasty procedure. CASE SUMMARY: A 15-year-old female visited our clinic after the onset of severe pain and decreased visual acuity while receiving a local anesthetic injection in the upper blepharon for a blepharoplasty procedure. At the first clinical visit, visual acuity was hand motion and an accurate anterior chamber examination was difficult because of corneal edema. The Seidel test was negative. On corneal optical coherence tomography, the corneal thickness was 1,580 µm without any sign of Descemet's membrane detachment. We prescribed 5% NaCl four times a day and prednisolone acetate eight times a day. On the next day after injury, the corneal edema was significantly improved (central corneal thickness: 660 µm), and Descemet's membrane detachment was still not observed. One week after injury, the naïve visual acuity was 20/20, the central corneal thickness was 560 µm, and the endothelial cell count was 3,260 cells/cm². Three weeks after injury, the corneal edema was fully resolved and only slight temporal corneal haziness remained. After 2 months, the cornea was clear without any subjective discomfort. CONCLUSIONS: Corneal edema without Descemet's membrane detachment can be resolved spontaneously without aggressive treatment such as gas or air injection. However, endothelial cell count and corneal opacity need to be monitored on follow up exam. This clinical experience suggests that severe corneal edema in anterior stromal layer could be spontaneously resolved without severe complication.
