PURPOSE: To investigate the risk factors of diabetic nephropathy in patients with diabetic retinopathy requiring panretinal photocoagulation (PRP) and the visual prognosis. METHODS: A retrospective review of electronic medical records was conducted at Seoul St. Mary's Hospital, comprising 103 patients with type 2 diabetes mellitus and diabetic retinopathy who underwent PRP from 1996 to 2005. Patients with type 1 diabetes mellitus, non-diabetic renal disease, non-diabetic retinal disease, visually significant ocular disease, high-risk proliferative diabetic retinopathy, and advanced diabetic retinopathy were excluded. The patients were divided into three groups: no nephropathy (group 1, n = 45), microalbuminuria (group 2, n = 16), and advanced nephropathy (group 3, n = 42). Duration of diagnosis of retinopathy and nephropathy, glycosylated hemoglobin, visual acuity, complications, and treatment history were investigated. RESULTS: The mean glycosylated hemoglobin of group 3 (8.4 ± 1.2) was higher than that of group 1 (7.7 ± 1.0) or group 2 (7.7 ± 1.0) (p = 0.04). Mean interval from PRP to diagnosis of nephropathy was 8.8 ± 6.0 years in group 2 and 8.7 ± 4.9 years in group 3. The significant decrease in visual acuity in group 3 (28 eyes, 35.9%) was significantly higher than that in group 1 (15 eyes, 18.1%, p = 0.01) or group 2 (6 eyes, 20.7%, p = 0.03). Only vitreous hemorrhage showed a significantly higher incidence in groups 2 and 3 than in group 1 (p = 0.02). Multivariate regression analysis revealed that female sex and lower glycosylated hemoglobin were significantly associated with a protective effect on development of nephropathy. CONCLUSIONS: In the clinical setting, many patients with PRP-requiring diabetic retinopathy develop nephropathy an average of 8 to 9 years after PRP. Male sex and higher glycosylated hemoglobin could be risk factors of nephropathy.

BACKGROUND: To analyze the results of court rulings about medical litigations related to cataract surgery in Korea. METHODS: We collected 50 anonymized judgements regarding cataract surgery between 2000 and 2016 and analyzed the reasons for the medical litigations, the court rulings, the reasons for compensation, and the amount claimed and finally awarded. RESULTS: Forty-eight litigations (96%) resulted from errors in treatment, and the reasons were as follows: endophthalmitis, dissatisfaction of visual outcome or ocular discomfort, bullous keratopathy or corneal opacity, retinal detachment, glaucoma or vitreous hemorrhage due to the progression of an underlying diabetic retinopathy, and others in order. Two litigations (4%) arose due to errors in diagnosis. Among the 50 final cases, 21 litigations (42%) were decided in favor of the plaintiff, and 29 litigations (58%) were decided against the plaintiff and dismissed. Ten cases awarded damages to the plaintiffs because of a violation of duty of care, and 11 cases awarded damages due to a violation of informed consent. When comparing cases with errors in diagnosis to cases with errors in treatment, there was no significant difference in the relative risk of a defendant's verdict (P = 0.503). The total amount of awarded damages was KRW 439,124,496 (USD 399,204), and the average amount was KRW 20,910,690 (USD 19,010). CONCLUSION: Nearly half of the cases were decided in favor of the plaintiff due to the violation of informed consent. This study's results will be helpful in understanding the results of medical litigations regarding cataract surgery and reducing future lawsuits.

PURPOSE: To report a case of Roth spots, panuveitis, and infectious mononucleosis in a healthy adult. CASE SUMMARY: An immunocompetent 30-year-old male visited our clinic complaining of reduced visual acuity and a floating sense in both eyes of 2 days. He had experienced flu-like symptoms including fever, sore throat, myalgia, and malaise for 10 days before visual acuity decreased. His best-corrected visual acuity was 20/25 in both eyes and inflammatory cells were found in both the anterior chambers and the vitreous. Funduscopy revealed multiple retinal hemorrhages and Roth spots in both eyes. We prescribed topical steroid eye drops. A peripheral blood test revealed mild leukocytosis with lymphocytosis (60%) consisted of atypical lymphocyte (7%). Serologic examinations were positive for cytomegalovirus (CMV) immunoglobulin M (IgM) Ab and Epstein-Barr virus IgM Ab. A polymerase chain reaction for blood CMV was positive. The presumptive clinical diagnosis was Roth spots and panuveitis associated with infectious mononucleosis. Three weeks later, no inflammatory cells were apparent in the anterior chamber or vitreous. Best-corrected visual acuity had recovered to 20/20 in both eyes, and the retinal hemorrhage had completely disappeared. CONCLUSIONS: Roth spots and panuveitis can be present in patients with infectious mononucleosis, which should thus be included in the differential diagnosis of Roth spots.

PURPOSE: To report fundus photography using a smartphone in an infant with abusive head trauma. CASE SUMMARY: An 8-month-old male infant presented to the emergency room with decreased consciousness and epileptic seizures that the parents attributed to a fall from a chair. He had no external wounds or fractures to the skull or elsewhere. However, computerized tomography of the brain revealed an acute subdural hematoma in the right cranial convexity and diffuse cerebral edema, leading to a midline shift to the left and effacement of the right lateral ventricle and basal cistern. The attending neurosurgeon promptly administered a decompressive craniectomy. Immediately after the emergency surgery, a fundus examination revealed numerous multi-layered retinal hemorrhages in the posterior pole extending to the periphery in each eye. He also had white retinal ridges with cherry hemorrhages in both eyes. We acquired retinal photographs using the native camera of a smartphone in video mode. The photographer held the smartphone with one hand, facing the patient's eye at 15–20 cm, and held a 20 diopter condensing lens at 5 cm from the eye in the other hand. Our documentation using a smartphone led to a diagnosis of abusive head trauma and to obtain the criminal's confession, because the findings were specific for repetitive acceleration-deceleration forces to an infant`s eye with a strong vitreoretinal attachment. CONCLUSIONS: This ophthalmic finding had a key role in the diagnosis of abusive head trauma. This case presented the diagnostic use of a smartphone for fundus photography in this important medicolegal case.

PURPOSE: To evaluate the efficacy of intravitreal aflibercept monotherapy in submacular hemorrhage (SMH) secondary to wet age-related macular degeneration (AMD). METHODS: This study included 25 eyes in 25 patients with SMH involving the fovea secondary to wet-AMD. All patients were treated with three consecutive monthly intravitreal aflibercept (2.0 mg/0.05 mL) injections, followed by as-needed reinjection. They were followed for at least 6 months. Best-corrected visual acuity (BCVA), central foveal thickness (CFT), and area of SMH were measured at diagnosis, as well as at 3 and 6 months after treatment initiation. RESULTS: The BCVA significantly improved from 0.79 ± 0.41 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.54 ± 0.41 logMAR at 6 months (p < 0.001). BCVA ≥3 lines and stable vision were observed in 96% of the eyes. The CFT significantly decreased from 560.8 ± 215.3 µm at baseline to 299.8 ± 160.2 µm at 6 months (p < 0.001). The area of SMH significantly decreased from 10.5 ± 7.1 mm² at baseline to 1.8 ± 6.5 mm² at 6 months (p < 0.001). The BCVA, CFT, and area of SMH at baseline, as well as duration of symptoms, all correlated with BCVA at the 6-month follow-up. CONCLUSIONS: Intravitreal injection of aflibercept is an effective treatment option for patients with SMH secondary to wet-AMD; however, there may be limited efficacy in eyes with large SMH area and cases in which treatment is delayed.

PURPOSE: To report cases of macular serous retinal detachment caused by excessive intraoperative endolaser in patients with diabetic vitreous hemorrhage. Macular serous retinal detachment was improved by systemic steroid therapy. CASE SUMMARY: A 64-year-old male (case 1) and a 67-year-old female (case 2) treated with vitrectomy and endolaser (case 1, 3,184 shots; case 2, 1,734 shots) because of diabetic vitreous hemorrhage visited our out-patient clinic with blurred vision. Best corrected visual acuity (BCVA) in case 1 was hand motion and 0.03 in case 2. Fundus examination and optical coherence tomography (OCT) revealed extensive subretinal fluid accumulation of the posterior pole. With the diagnosis of macular serous retinal detachment caused by excessive intraoperative endoaser, oral steroid (40 mg/qd, 5 days) was administered and then later reduced in case 1. In case 2, we administered intravenous high-dose steroid (250 mg/qid, 3 days). After systemic steroid therapy, BCVA was improved to 20/30 in case 1 and 20/40 in case 2 and OCT showed the subretinal fluid was resolved. CONCLUSIONS: During diabetic retinopathy surgery, excessive endolaser induced macular serous retinal detachment and systemic steroid therapy was necessary in diabetic patients. Thus, physicians should be well acquainted with this complication.

PURPOSE: To evaluate the visual and anatomical outcomes for neovascular age-related macular degeneration with submacular hemorrhage after intravitreal injections of tenecteplase (TNK), anti-vascular endothelial growth factor (VEGF) and expansile gas. METHODS: This study was a retrospective clinical case series following 25 eyes of 25 patients. All patients received a triple injection using 0.05 mL TNK (50 µg), 0.05 mL anti-VEGF and 0.3 mL of perfluoropropane gas. Retreatment with anti-VEGF was performed as needed. Preoperative and postoperative best-corrected visual acuity and central retinal thickness were analyzed. RESULTS: The mean logarithm of the minimum angle of resolution of best-corrected visual acuity improved significantly from 1.09 ± 0.77 at baseline to 0.52 ± 0.60 at 12 months (p < 0.001). The mean central retinal thickness also improved significantly from 545 ± 156 at baseline to 266 ± 107 at 12 months (p < 0.001). A visual improvement of 0.3 logarithm of the minimum angle of resolution unit or more was achieved in 15 eyes (60%). During the 12 postoperative months, an average of 4.04 intravitreal anti-VEGF injections was applied. CONCLUSIONS: A triple injection of TNK, anti-VEGF, and a gas appears to be safe and effective for the treatment of submacular hemorrhage secondary to neovascular age-related macular degeneration.

Protein C (PROC) deficiency is caused by mutations in the PROC gene on chromosome 2q14.3. Patients with PROC deficiency typically present distinguished purpura, intracerebral and intravascular coagulopathy, and ophthalmologic complications. Here, we report a rare severe form of PROC deficiency resulting from a compound heterozygosity in PROC. The patient was a 5-day-old female neonate born at 39 weeks of gestation with a birth weight of 2,960 g. She was transferred to our hospital with running a fever at 38.5℃ and with dark red patches on her feet. At admission, a complete blood count showed no specific findings, but levels of PROC and protein S were abnormally low (1% and 68%, respectively). Magnetic resonance imaging revealed intracerebral hemorrhaging and parenchymal damage with dysplasia of the brain. Ophthalmologic examination revealed vitreous hemorrhaging with retinal detachment. Genetic testing revealed a missense mutation (Arg211Trp) and a frameshift mutation (Gly239Serfs*8) in PROC, inherited from the father and mother, respectively. The patient recovered from purpura after undergoing ventriculoperitoneal shunting and treatment with fresh frozen plasma, warfarin sodium, and PROC concentrate. This is the first report of severe neonatal PROC deficiency with purpura fulminans, vitreous hemorrhage, and intracerebral hemorrhage confirmed via PROC genetic testing, which identified a rare compound heterozygosity of PROC.
