RESUMEN
Purpose@#Since the introduction of robotic surgery, robots for colorectal cancer have replaced laparoscopic surgery, and a single-port robot (SPR) platform has been launched and is being used to treat patients. We analyzed the learning curve and initial complications of using an SPR platform in colorectal cancer surgery. @*Methods@#We reviewed 39 patients who underwent SPR colectomy from April to October 2019. All surgeries were performed by the same surgeon using an SPR device. A learning curve was generated using the cumulative sum methodology to assess changes in total operation time, docking time, and surgeon console time. We grouped the patients into 3 groups according to the time period: the first 11 were phase 1, the next 11 were phase 2, and the last 17 were phase 3. @*Results@#The mean age of the patients was 61.28±13.03 years, and they had a mean body mass index of 23.79±2.86 kg/m2. Among the patients, 23 (59.0%) were male, and 16 (41.0%) were female. The average operation time was 186.59±51.30 minutes, the average surgeon console time was 95.49±35.33 minutes, and the average docking time (time from skin incision to robot docking) was 14.87±10.38 minutes. The surgeon console time differed significantly among the different phases (P<0.001). Complications occurred in 8 patients: 2 ileus, 2 postoperation hemoglobin changes, 3 urinary retentions, and 1 complicated fluid collection. @*Conclusion@#In our experience, the learning curve for SPR colectomy was achieved after the 18th case.
RESUMEN
Purpose@#To investigate cases of vitreous opacity (VO) similar to asteroid hyalosis (AH) after intravitreal brolucizumab injection. @*Methods@#A retrospective chart review was conducted to identify cases showing VO similar to AH among patients who received intravitreal brolucizumab injections at our retinal clinic from January 2022 to January 2023. @*Results@#A total of 220 brolucizumab injections were administered at our hospital. VO, showing yellow-white brilliant reflective particles, was found in six patients (2.7%). When VO occurred, all patients complained of floaters, although none of them complained of other symptoms including decreased visual acuity, pain, or conjunctival redness. The mean number of brolucizumab injections was 2.57 ± 2.38. No significant visual impairment was observed while VO was present. VO improved in all cases, and four cases improved without any treatment. The mean interval from onset to disappearance of VO was 8.0 ± 3.1 weeks. @*Conclusions@#VO, similar to AH, can occur with a relatively high probability after intravitreal brolucizumab injections. Patients complained of severe floaters, but VO was not accompanied by other symptoms including vision impairment, injection, and pain. The VO disappeared after approximately 4 to 14 weeks. In case that other inflammatory findings are not severe, close follow-up without treatment may be sufficient. If a patient complains of floaters after an intravitreal brolucizumab injection, close fundus observation is necessary to evaluate the VO.
RESUMEN
Purpose@#The advances in the treatment of retinoblastoma have enabled salvaging the globe in advanced stages with intra-arterial chemotherapy (IAC). We developed a strategy of alternate application of systemic intravenous chemotherapy (IVC) and IAC (referred to as alternate systemic IVC and IAC; ASIAC) to reduce central nervous metastases during IAC and examined its efficacy and safety in eye globe salvage in this study. @*Materials and Methods@#Between January 2010 and February 2021, 43 eyes of 40 patients received ASIAC treatment for retinoblastoma at the Yonsei Cancer Center, Yonsei University Health System. Their medical records were reviewed retrospectively to evaluate the eye salvage rate (ESR), defined from diagnosis to enucleation. High-risk retinoblastoma was defined as group D or E by the International Classification of Retinoblastoma. @*Results@#The study enrolled 38 and five cases of high-risk and low-risk retinoblastoma, respectively. In total, 178 IAC and 410 IVC courses were administered, with a median of 4 (interquartile range [IQR], 3.0 to 5.0) IAC and 9 (IQR, 6.0 to 11) IVC courses per eye, respectively. The 5-year ESR was 60.4%±8.7% for the whole cohort, 100% for low-risk retinoblastoma, and 53.6%±9.8% for high-risk retinoblastoma. Among those diagnosed since 2015, the 5-year ESR for high-risk retinoblastoma was 63.5%±14.0%. Fifteen eyes underwent enucleation; no viable tumor was found in three enucleated eyes. There were no deaths in this cohort. @*Conclusion@#Primary IAC-IVC (i.e., ASIAC) for patients with retinoblastoma was tolerable and effective in salvaging the eye and maintaining survival.
RESUMEN
Midgut malrotation (MM) is a rare anatomical abnormality that complicates the diagnosis and management of acute abdominal pain. Moreover, appendicitis and diverticulitis of the sigmoid colon can be considered when there is pain in the lower left abdomen. The patient in this case report was an 86-year-old female who had continuous abdominal pain two days before the visit to the emergency room. Abdominopelvic computed tomography revealed MM, and uneven concentric wall thickening from the distal descending colon to the proximal sigmoid colon with surrounding fatty infiltration was confirmed in the left lower abdomen. Moreover, the possibility of left-sided appendicitis due to MM could not be excluded. The patient’s abdominal pain increased next day. The surgery was performed laparoscopically, and the location of the appendix was reversed. The surgical findings revealed an abscess caused by perforation from inflammation of the proximal part of the appendix, and the sigmoid colon adhered mildly to the side immediately behind the abscess cavity. The base of the appendix was intact, and only an appendectomy was performed. Left-sided appendicitis due to MM was discriminated from the diverticulitis of the sigmoid colon. Diagnostic laparoscopic surgery through a physical examination based on the surgeon’s experience is important.
RESUMEN
Purpose@#To examine the refractive errors, retinal manifestations, and genotype in tuberous sclerosis complex (TSC) patients in a Korean population. @*Materials and Methods@#A total of 98 patients with TSC were enrolled in Severance Hospital for a retrospective cohort study. The number of retinal astrocytic hamartoma and retinal achromic patch within a patient, as well as the size, bilaterality, and morphological type were studied. In addition, the refractive status of patients and the comorbidity of intellectual disability and epilepsy were also examined. @*Results@#Retinal astrocytic hamartoma was found in 37 patients, and bilateral invasion was observed in 20 patients (54%). TSC1 mutation was associated with myopia (p=0.01), while TSC2 mutation was associated with emmetropia (p=0.01). Retinal astrocytic hamartoma was categorized into three morphological types and examined as follows: type I (87%), type II (35%), and type III (14%). Single invasion of retinal astrocytic hamartoma was identified in 32% of the patients, and multiple invasions in 68%. The TSC1/ TSC2 detection rate was 91% (41/45). Among them, TSC1 variant was detected in 23 patients (54%), whereas TSC2 variant was detected in 18 patients (40%). The results showed that TSC2 mutations are correlated with a higher rate of retinal astrocytic hamartoma involvement (all p<0.05), and multiple and bilateral involvement of retinal hamartomas (all p<0.05). However, the size of retinal astrocytic hamartomas, comorbidity of epilepsy, or intellectual disability did not show correlation with the genetic variant. @*Conclusion@#TSC1 variant patients were more myopic, while TSC2 variant patients showed association with more extensive involvement of retinal astrocytic hamartoma.
RESUMEN
Purpose@#To report clinical outcomes of a scleral fixation technique of a hydrophobic acrylic intraocular lens with eyelets using 8-0 polypropylene suture. @*Methods@#Nine eyes of nine patients who underwent combined pars plana vitrectomy and sclera fixation of an intraocular lens using this technique were analyzed. @*Results@#The mean follow-up period was 7.11 months (range, 6–12 months), and there was a significant visual improvement at 6 months after surgery. The mean logarithm of the minimum angle of the resolution changed from 0.54 at baseline to 0.29 at postoperative 6 months (p = 0.016). The mean postoperative spherical equivalent at 6 months was -0.90 ± 0.90 diopters, and the mean predictive error was -0.49 ± 0.62 diopters. @*Conclusions@#Postoperative visual and refractive outcomes were favorable, and the positions of intraocular lenses were well centered in all cases. This technique could be a useful alternative for surgeons without easy access to Gore-Tex suture.
RESUMEN
Purpose@#To evaluate the difference in each retinal layer thickness in central retinal vein occlusion (CRVO) with resolved macular edema after intravitreal antivascular endothelial growth factor injection and normal contralateral eyes.. @*Methods@#Patients with ischemic and nonischemic CRVO whose macular edema resolved after intravitreal antivascular endothelial growth factor injections and did not recur for at least 6 months, and a normal contralateral eye were enrolled. Each retinal layer thickness between CRVO and normal contralateral eyes was compared according to Early Treatment Diabetic Retinopathy Study subfields using spectral domain optical coherence tomography. @*Results@#The thicknesses of outer nuclear layer, photoreceptor layer, and retinal pigment epithelium in central ring, ganglion cell layer, inner plexiform layer, outer nuclear layer, and photoreceptor layer in the inner ring, and ganglion cell layer in the outer ring of CRVO eyes were significantly thinner than those of normal contralateral eyes (all p < 0.05). Whereas, inner nuclear layer and outer plexiform layer thicknesses in central ring of CRVO eyes were 23.86 ± 8.8 and 25.76 ± 7.6 μm, respectively, which was significantly thicker than those of normal contralateral eyes (19.52 ± 7.7 and 22.76 ± 6.5 μm; p = 0.019 and p = 0.043, respectively). Additionally, the mean best-corrected visual acuity of CRVO eyes were significantly correlated with photoreceptor layer thickness in central ring (p = 0.005). @*Conclusions@#In CRVO eyes with resolved macular edema, the outer retinal layers were thinner as well as inner retinal layers, whereas inner plexiform layer and outer nuclear layer were thicker than normal fellow eyes. Additionally, photoreceptor layer thickness in foveal area had a significant impact on visual acuity in CRVO.
RESUMEN
We sought to analyze the efficacy of adalimumab in active noninfectious uveitis, and evaluate its efficacy and safety for the management of refractory noninfectious uveitis in Korean patients. A retrospective observational study was conducted. A total of 23 eyes of 14 Korean patients with noninfectious uveitis refractory to conventional treatment, including corticosteroid and immunosuppressive agents, were treated with adalimumab between December 2017 and February 2020. The primary outcomes were vitreous haziness grades, anterior chamber cell grades, and central macular thickness measured prior to injection and at 1, 3, 6, and 12 months after the first adalimumab injection. Among the 23 eyes, 14 eyes (60.9%) were diagnosed with panuveitis and 9 eyes (39.1%) with posterior uveitis [mean follow-up period: 22.3 months (7–27)]. The most common etiologic diagnoses requiring adalimumab injection were Behçet's disease (9 eyes, 39.1%), followed by undifferentiated inflammation (6 eyes, 26.1%), Vogt-Koyanagi-Harada disease (3 eyes, 13.0%), psoriasis (2 eyes, 8.7%), serpiginous chorioretinopathy (2 eyes, 8.7%), and systemic lupus erythematosus (1 eye, 4.3%). At the 1-year follow-up after the first injection, anterior chamber cell grade decreased from 0.5±0.4 to 0.3±0.4, and vitreous haziness grade decreased from 1.1±1.1 to 0.3±0.5 (p<0.05). Central macular thickness improved from 347.2±98.1 µm to 264.3±61.1 µm (p<0.05). Adalimumab injection in patients with refractory noninfectious uveitis decreased the anterior chamber cell grade, vitreous haziness grade, and central macular thickness with no severe side effect. Overall, adalimumab injection may, therefore, be an effective and relatively safe treatment modality for noninfectious uveitis in Korean patients.
RESUMEN
Background/Aims@#The incidence of stercoral perforation of the colon (SPC) is expected to rise, given the increased life expectancy and the aging population. On the other hand, the prognostic factors of mortality after surgery for SPC remain unclear. This study examined the prognostic factors of patients with SPC after surgery. @*Methods@#The medical records of 145 patients who underwent surgery for colonic perforation between April 2010 and May 2019 were reviewed retrospectively. In 145 patients, 22 patients who underwent SPC surgery were categorized into the following two groups according to in-hospital survival after surgery: alive (group A, n=15) and dead (group B, n=7). @*Results@#In all enrolled patients, the mean age was 75.7±9.0 years, with a female predominance (female patients, n=19, 86.4%). Sixteen patients (72.7%) had chronic constipation with medications, and five patients (22.7%) were bedridden. The rate of preoperative bedridden status was significantly higher in group B than group A (6.7% vs. 57.1%; p=0.021). Univariate analysis revealed immobility, a sequential organ failure assessment (SOFA) score, and lactate levels of more than 2.0 mmol/L to be factors associated with increased mortality rates in the postoperative period. Multivariate analysis revealed abnormal lactate levels to be the only factor related to mortality (hazard ratio 16.50, 95% CI 1.48-183.07, p=0.022). @*Conclusions@#Preoperative abnormal serum lactate levels may be a risk factor for mortality after surgery in patients with stercoral perforation. Further research will be needed to identify the postoperative prognostic SPC factors.
RESUMEN
Purpose@#The impact of postoperative complications on long-term oncologic outcome after radical colorectal cancer surgery is controversial. The aim of this study was to examine the risk factors and oncologic outcomes of surgery-related postoperative complication groups. @*Methods@#From January 2010 to December 2010, 310 patients experienced surgery-related postoperative complications after radical colorectal cancer surgery. These stage I–III patients were classified into 2 subgroups, minor (grades I, II) and major (grades III, IV) complication groups, according to extended Clavien-Dindo classification system criteria. Clinicopathologic differences between the 2 groups were analyzed to identify risk factors for major complications. The diseasefree survival rates of surgery-related postoperative complication groups were also compared. @*Results@#Minor and major complication groups were stratified with 194 patients (62.6%) and 116 patients (37.4%), respectively. The risk factors influencing the major complication group were pathologic N category and operative method. The prognostic factors associated with disease-free survival were preoperative perforation, perineural invasion, tumor budding, and receiving neoadjuvant therapy. With a median follow-up period of 72.2 months, the 5-year disease-free survival rates were 84.4% in the minor group and 78.5% in the major group, but there was no statistical significance between the minor and major groups (P = 0.392). @*Conclusion@#Advanced cancer and open surgery were identified as risk factors for increased surgery-related major complications after radical colorectal cancer surgery. However, severity of postoperative complications did not affect disease-free survival from colorectal cancer.
RESUMEN
PURPOSE: To investigate the efficacy, safety, and anatomical outcomes associated with intravitreal anti-vascular endothelial growth factor (VEGF) treatment of retinopathy of prematurity (ROP). METHODS: We performed a retrospective review of intravitreal anti-VEGF (bevacizumab or ranibizumab) treatment of 153 eyes (83 infants) diagnosed with ROP at two tertiary hospitals from June 2011 to January 2017. The primary outcome was the rate of recurrence requiring additional treatment; secondary outcomes included incidence of major complications and final refractive error. RESULTS: A total of 101 eyes were treated with bevacizumab, and 52 with ranibizumab. The bevacizumab and ranibizumab groups were characterized by mean birthweights of 941.8 ± 296.1 and 1,257.7 ± 514.5 g, gestational ages at birth of 26.9 ± 1.9 and 28.1 ± 3.2 weeks, and postmenstrual ages at treatment of 40.4 ± 2.4 and 39.2 ± 2.3 weeks, respectively. The two groups differed significantly in birthweights and gestational ages at birth, but not in postmenstrual ages at treatment. The mean follow-up duration was 30.9 ± 18.4 months for the bevacizumab group, and 13.9 ± 12.5 months for ranibizumab. More cases were classified as zone 1 ROP in the ranibizumab group (44.2% vs. 11.9%, p < 0.001). Major surgical interventions included scleral encircling and vitrectomy (one and two eyes, respectively, both in the bevacizumab group). Retinal detachment was noted in one eye treated with bevacizumab. There was no significant difference in the most recent spherical equivalence for the two groups (+0.10 ± 3.66 and +0.22 ± 3.00 diopters for bevacizumab and ranibizumab, respectively). Univariable analysis revealed that only ROP stage influenced the occurrence of major complications (odds ratio, 9.046; p = 0.012). CONCLUSIONS: Intravitreal anti-VEGF treatment of ROP with both bevacizumab and ranibizumab achieved stable retinal vascularization with a low rate of complications and recurrence. Ranibizumab achieved similar anatomical outcomes as bevacizumab, without additional risk for major complications.

PURPOSE: To report a case of candida endogenous endophthalmitis in healthy women who had received extraction of wisdom tooth. CASE SUMMARY: A 65-year-old medically healthy woman who had received extraction of wisdom tooth two weeks ago, presented with floater symptoms in her left eye. Best-corrected visual acuity was 20/40 and intraocular pressure was 17 mmHg in her left eye. Inflammatory cells were found in the anterior chamber and vitreous. Fluorescein angiography showed multiple hypofluorescence without vascular leakage. With provisional diagnosis of intermediate uveitis, she was prescribed oral steroid for two weeks. After that, inflammatory cells in anterior chamber was reduced but vitreous imflammatory cell was increased and fundus examination detected newly developed infiltrated lesion at superotemporal area. The patient was presumed to have fungal endophthalmitis and immediate intravitreal voriconazole injection was performed. Three days after intravitreal voriconazole injection, diagnostic vitrectomy and intravitreal voriconazole injection were performed. Vitreous cultures revealed the growth of Candida albicans. Despite the treatment, inflammatory response in anterior chamber and vitreous rapidly increased and visual acuity was decreased to hand movement. We changed anti-fungal agent, voriconazole to Amphotericin B. Additional three-time intravitreal injection was done and therapeutic vitrectomy with oil injection were performed. After treatment, the patient's fundus markedly improved and inflammatory response was decreased. CONCLUSIONS: This case report shows candida endophthalmitis in healthy woman who had received extraction of wisdom tooth. So to diagnose endophthalmitis, patient's medical history should carefully be checked including dental care history who presented with vitreous inflammation and inflammatory infiltrated lesion at fundus.

PURPOSE: To describe the visual recovery and prognostic factors after macular hole surgery. METHODS: A retrospective chart review was conducted. Charts of patients with idiopathic macular holes who underwent surgery by a single surgeon at Severance Hospital between January 1, 2013 and July 31, 2015 were reviewed. The best-corrected visual acuity (BCVA) score was recorded preoperatively and at 1 day and 1, 3, 6, 9, and 12 months after surgery. The variables of age, sex, macular hole size, basal hole diameter, choroidal thickness, and axial length were also noted. RESULTS: Twenty-six eyes of 26 patients were evaluated. Twenty-five patients (96.2%) showed successful macular hole closure after the primary operation. The BCVA stabilized 6 months postoperatively. A large basal hole diameter (p = 0.006) and thin choroid (p = 0.005) were related to poor visual outcomes. Poor preoperative BCVA (p < 0.001) and a thick choroid (p = 0.020) were associated with greater improvement in BCVA after surgery. CONCLUSIONS: Visual acuity stabilized by 6 months after macular hole surgery. Choroidal thickness was a protective factor for final BCVA and visual improvement after the operation.

PURPOSE: Uveal melanoma has a very poor prognosis despite successful local primary tumor treatment. In this study, we investigated prognostic factors that more accurately reflected the likelihood of recurrence and survival and delineated a prognostic model that could effectively identify different risk groups based on initial clinical parameters. MATERIALS AND METHODS: Prognostic factors associated with distant recurrence, recurrence-free survival (RFS), progression-free survival, and overall survival from distant recurrence to death (OS2) were analyzed in 226 patients with stage I-III uveal melanoma who underwent primary local therapy. RESULTS: Forty-nine patients (21.7%) had distant recurrences, which occurred most frequently in the liver (87.7%). In a multivariate analysis, local radiotherapy improved RFS among patients with multiple recurrence risk factors relative to excision (not reached vs. 19.0 months, p=0.004). Patients with BRCA1-associated protein-1 (BAP1)–negative primary tumors showed a longer RFS duration after primary treatments, while those with BAP1-negative metastatic tissues had a shorter OS2 compared to those with BAP1-positive tumors, both not statistically insignificance (RFS: not reached vs. 82.0 months, p=0.258; OS2: 15.7 vs. 24.4 months, p=0.216). Male sex (hazard ratio [HR], 3.79; p=0.012), a short RFS (HR, 4.89; p=0.014), and a largest metastatic tumor linear diameter ≥ 45 mm (HR, 5.48; p=0.017) were found to correlate with worse post-recurrence survival. CONCLUSION: Risk factors could be used to classify uveal melanoma cases and subsequently direct individual treatment strategies. Furthermore, metastasectomy appears to contribute to improved survival outcomes.

Autoimmune retinopathy (AIR) is an immune-mediated retinopathy, resulting from an immunologic process caused by the aberrant recognition of retinal antigens as autoantigens. The diagnosis of AIR involves the detection of antiretinal antibodies with concurrent clinical and electrophysiological evidence of retinopathy. A 40-year-old patient presented with progressive loss of bilateral vision over several months. A fundus examination was unremarkable. Spectral domain optical coherence tomography revealed a blurred photoreceptor ellipsoid zone at the subfoveal region in both eyes with more prominent disruption in the left eye. Full-field electroretinography (ERG) showed relatively normal rod and cone responses in the right eye, and decreased photopic bwaves with minimal attenuation of a-waves in the left eye. Multifocal ERG demonstrated slightly reduced amplitude of the inner segment ring in the right eye and decreased amplitudes and delayed latencies of all modalities in the left eye. The patient was suspected to have AIR and it was supported by positive Western blots for 23-kDa protein, enolase (46-kDa), aldolase (40-kDa), 62-kDa and 78-kDa proteins and by immunohistochemical staining of human retinal bipolar and ganglion cells. Despite the immunosuppressive treatment, the destruction of the retinal photoreceptors progressed, and immunosuppressive interventions produced very little visual improvement. We report on what is, to the best of our knowledge, the very first case of serologically confirmed nonparaneoplastic AIR in Korea.

PURPOSE: To verify the effect of preservative-free Dorzolamide/Timolol fixed combination (PFDTC) on intraocular pressure (IOP) elevation after vitrectomy. METHODS: We retrospectively reviewed medical records of 33 patients who used PFDTC after pars plana vitrectomy. All patients' visual acuity and IOP was measured and symptoms of conjunctival irritation were investigated through survey and slit lamp examination. RESULTS: Before vitrectomy, the mean IOP was 13.6 ± 4.4 mm Hg which was elevated to 31.7 ± 5.4 mm Hg after vitrectomy (p < 0.001) and applying eyedrop lowered the mean IOP to 17.2 ± 7.0 mm Hg (p < 0.001). Regardless of tamponade material type, all elevated IOP decreased (p < 0.001) and the IOP of all 33 eyes did not rise to over 30 mm Hg again. No additional surgery for IOP control was needed during two-month follow-up period. Of the 33 patients using PFDTC, patients who felt discomfort were five (15.2%) and no patients showed side effects severe enough to stop use of eyedrop. CONCLUSIONS: PFDTC is an anti-glaucomatic agent which can reduce the IOP by inhibiting aqueous humor production. Without need for additional surgery, the eyedrop can effectively lower elevated post-vitrectomy IOP, with expectation of good patient compliance due to low risk of conjunctival irritation.

PURPOSE: To evaluate the accuracy of postoperative refractive outcomes of combined phacovitrectomy for epiretinal membrane (ERM) in comparison to cataract surgery alone. MATERIALS AND METHODS: Thirty-nine eyes that underwent combined phacovitrectomy with intraocular lens (IOL) implantation for cataract and ERM (combined surgery group) and 39 eyes that received phacoemulsification for cataract (control group) were analyzed, retrospectively. The predicted preoperative refractive aim was compared with the results of postoperative refraction. RESULTS: In the combined surgery group, refractive prediction error by A-scan and IOLMaster were -0.305+/-0.717 diopters (D) and -0.356+/-0.639 D, respectively, compared to 0.215+/-0.541 and 0.077+/-0.529 in the control group, showing significantly more myopic change compared to the control group (p=0.001 and p=0.002, respectively). Within each group, there was no statistically significant difference in refractive prediction error between A-scan and IOLMaster (all p>0.05). IOL power calculation using adjusted A-scan measurement of axial length based on the macular thickness of the normal contralateral eye still resulted in significant postoperative refractive error (all p<0.05). Postoperative refraction calculated with adjusted axial length based on actual postoperative central foveal thickness change showed the closest value to the actual postoperative achieved refraction (p=0.599). CONCLUSION: Combined phacovitrectomy for ERM resulted in significantly more myopic shift of postoperative refraction, compared to the cataract surgery alone, for both A-scan and IOLMaster. To improve the accuracy of IOL power estimation in eyes with cataract and ERM, sequential surgery for ERM and cataract may need to be considered.

PURPOSE: To compare clinical, angiographic, and optical coherence tomographic characteristics between eyes with acute Vogt-Koyanagi-Harada (VKH) disease and eyes with acute bilateral central serous chorioretinopathy (CSC), and to demonstrate distinguishing features between the two diseases in confusing cases. METHODS: The medical records of 35 patients with VKH disease and 25 patients with bilateral CSC were retrospectively reviewed. Characteristics according to slit-lamp biomicroscopy, ophthalmoscopy, fundus photography, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography were compared between the two diseases. RESULTS: Five of 35 patients (10 of 70 eyes, 14.3%) with VKH disease were initially misdiagnosed as CSC patients, and six of 25 patients (12 of 50 eyes, 24%) with bilateral CSC were initially misdiagnosed as patients with VKH disease. Pigment epithelial detachment in CSC and optic disc hyperemia in VKH disease show the highest positive predictive values of 100% for each disease. CONCLUSIONS: Optic disc hyperemia in VKH disease and pigment epithelial detachment in bilateral CSC are the most specific clinical manifestations of each disease at initial patient presentation.

PURPOSE: To report the first case of pigmented choroidal metastases without enucleation diagnosed with fine-needle aspiration biopsy. CASE SUMMARY: A 47-year-old male was referred to our clinic with a suspected diagnosis of choroidal melanoma in his left eye. Positron emission tomography-computer tomography used to evaluate systemic metastases revealed lung cancer. Pathology of the detected lung mass was primary lung neuroendocrine tumor. To differentiate choroidal metastasis and primary choroidal melanoma, we performed a fine-needle aspiration biopsy for choroidal tumors. The cytology showed results favoring metastatic atypical carcinoid and the patient was started on systemic chemotherapy. CONCLUSIONS: All pigmented choroidal tumors are not choroidal melanomas and choroidal metastases may be pigmented. The present case suggests that proper systemic evaluation and biopsy for suspected choroidal tumor could be helpful in diagnosis.

PURPOSE: To identify significant fluorescein angiographic (FA) characteristics associated with visual acuity (VA) in Behcet retinal vasculitis. MATERIALS AND METHODS: Retrospective review of 86 eyes of 48 patients (age: 35.6+/-10.2 years) with Behcet retinal vasculitis were performed. VA and FA findings as well as correlation between them were assessed. RESULTS: The mean initial VA of eyes with posterior pole-involved vasculitis (63 eyes; 73.3%) was significantly worse than that of those with peripheral vasculitis (23 eye; 26.7%) (logarithm of the minimum angle of resolution VA: 0.554+/-0.572 vs. 0.078+/-0.148; p<0.0001). Subgroup analysis revealed a more severe and diffuse pattern of vascular leakage in posterior pole-involved vasculitis compared to peripheral vasculitis (p<0.0001). Retinal vascular leakage (beta=0.345; p<0.0001), optic disc hyperfluorescence (beta=0.147; p=0.032), and macular leakage (beta=0.107; p=0.047) were significantly associated with worse initial VA. During the follow up (mean: 33.3+/-17.9 months), the change of leakage showed no significant correlation with change of VA in posterior pole-involved vasculitis (tau=0.199, p=0.092). CONCLUSION: Posterior pole involvement, the degree of retinal vascular leakage, optic disc hyperfluorescence, and macular leakage are significantly associated with VA in Behcet retinal vasculitis.
