ABSTRACT
(1) Indocyanine green angiography (ICG-A) shows the presence of mid-phase hyperfluorescent area in central serous chorioretinopathy (CSCR). However, their exact meaning remains uncertain. (2) The clinical and multimodal imaging findings of 100 patients (133 eyes) with CSCR, including the enhanced-depth-imaging OCT (EDI-OCT), blue-light fundus autofluorescence (BAF), fluorescein and indocyanine green angiography (FA and ICG-A) findings were reviewed. Mid-phase hyperfluorescent plaques (MPHP) were defined as fairly well circumscribed hyperfluorescent regions during the midphase of the ICG-A. The association between MPHP and other clinical/imaging parameters was assessed using a multiple logistic regression analysis. (3) MPHP were detected in 59.4% of eyes with CSCR. The chronic form of the disease, the presence of irregular pigment epithelium detachments (PED) and the retinal pigment epithelium (RPE) changes seen on FA were associated with the presence of MPHP in the multivariate analysis (p = 0.015; p = 0.018 and p = 0.002; respectively). OCT showed RPE bulges or PED in 98.7% of areas with MPHP and BAF showed changes in 57.3% of areas with MPHP. (4) MPHP were associated with a chronic form of CSCR and colocated with PED or RPE bulges. MPHP should be recognized as a sign of early RPE dysfunction before it is detected with BAF.
ABSTRACT
BACKGROUND/OBJECTIVES: To assess the ratio of scarred/active areas of fundus lesions in patients with presumed ocular toxoplasmosis. SUBJECTS/METHODS: Retrospective monocentric study of patients with presumed ocular toxoplasmosis seen between May 2004 and February 2018. Patients with a positive anti-Toxoplasma serology presenting characteristic fundus lesions. Cases with images of both baseline active and scarred lesions of the fundus were included. The borders of each active or scarred lesion were delineated on colour photographs by two independent observers and the area of the lesions was calculated using Digimizer 4.2.2 (MedCalc Software, Ostend, Belgium). The interobserver variability of the measures was recorded and their means were used for further calculations. To study the ratio of the area of scarred retinochoroiditis over the area of the baseline active lesion (R). RESULTS: A total of 171 cases (83 males, 88 females) with a mean age of 31.6 ± 13.8 years were included. The average areas of active and scarred retinochoroiditis were, respectively, 1.32 ± 1.59 and 1.79 ± 2.36 optic disc area. The average ratio between scarred and active areas of retinochoroiditis was 1.36 [range 0.54-2.18]. The administration of a systemic treatment [R = 1.25, p = 0.003], the absence of a pre-existing scar [R = 1.05, p < 0.001] and a peripapillary location of the lesion [R = 0.85, p < 0.001] were each significantly associated with smaller scarred/active area ratios. CONCLUSIONS: We assessed in a standardized manner the ratio of scarred/active areas of toxoplasmic lesions and showed that the area of scarred lesions was on average slightly larger than the area of active retinochoroiditis.

AIMS: Glucocorticoid intake is a well-established risk factor for central serous chorioretinopathy that belongs to the pachychoroid spectrum disease (PSD). The study aimed to assess the prevalence of PSD and analyse the choroidal phenotype in patients with Cushing syndrome. METHODS: A cross-sectional study was performed in Ophtalmopôle hôpital Cochin, Paris, France, with a systematic evaluation of hospitalized patients with Cushing syndrome, between November 2017 and July 2018. 56 eyes from 28 Cushing syndrome patients and 56 eyes of 28 age and gender-matched, and close spherical equivalent healthy participants were included. All patients underwent a complete ophthalmic examination including Enhanced-Depth Imaging (EDI)-Optical Coherence Tomography (OCT). Measures of subfoveal, 1000 µm nasal and 1000 µm temporal choroidal thicknesses were realized, and the presence of choroidal pachyvessels was evaluated. Hormonal tests evaluated the corticotropic axis. RESULTS: The number of eyes with PSD was significantly higher in Cushing syndrome patients as compared to controls (21.4% versus 3.6%, p = 0.004). In Cushing patients' eyes, 17.9% had a pachychoroid pigment epitheliopathy (PPE) and 3.6% had a polypoidal choroidal vasculopathy. Pachyvessels were more common in Cushing syndrome patients than in healthy subjects (71.4% versus 42.9%, p = 0.002). Mean subfoveal choroidal thickness was 331 ± 110 µm in Cushing patients, with no statistical difference between the two groups. There was no correlation between choroidal thickness and urinary and salivary cortisol levels. CONCLUSION: Patients with Cushing syndrome have a higher prevalence of PDS. An ophthalmologic specialized follow-up of these patients with EDI-OCT could detect chorioretinal abnormalities and adapt the surveillance of these patients.

Purpose: To assess the choroidal vascularity index (CVI) in birdshot chorioretinopathy (BSCR) patients.Methods: The CVI was calculated as the ratio of luminar area to the total subfoveal choroidal area on enhanced-depth imaging optical coherence tomography. Intraocular inflammation was defined by the presence of macular edema and/or vitritis and/or vasculitis and/or papillitis.Results: Eighty BSCR patients and 22 healthy controls were included. Foveal choroidal thickness was lower in the BSCR compared with the control group (p < 0.001). CVI was not different between the two groups. CVI was significantly higher in BSCR patients with inflammatory activity (p = 0.004). Using a multivariate linear regression model, longer disease duration was associated with lower CVI (p = 0.038), whereas the presence of papillitis was associated with a higher CVI (p = 0.003).Conclusions: The CVI was not different between the BSCR and the control group. However, the CVI may be used as a new tool for monitoring inflammatory activity in BSCR.

PURPOSE: Iris intraocular implants were developed to manage congenital or traumatic iris defects. However, they are also used to change the color of patient eyes. The aim of this retrospective series was to report complications in patients managed in France after cosmetic implantation. SETTING: Ophthalmological institutions and private ophthalmologists in France. DESIGN: Multicenter retrospective observational study. METHODS: Questionnaires were sent to all ophthalmology departments in university hospitals and to private ophthalmologists. This questionnaire listed demographic and clinical data for each implanted eye with a focus on safety, the description of ocular complications (corneal edema, endothelial cell loss, increased intraocular pressure, and intraocular inflammation), and the therapeutic management implemented. RESULTS: Forty-four questionnaires (87 eyes) were collected, and ultimately, 33 questionnaires (65 eyes) were considered complete and analyzed. Two types of implants were identified. Of the 65 eyes analyzed, only 5 eyes (7.7%) did not experience any complication and 60 eyes (92.3%) had at least 1 complication. The most commonly reported complication was corneal decompensation (78.5%). The diagnosis of glaucoma was made in over half (52.3%) of the cases. Explantation was needed in 81.5% of cases. The mean final visual acuity was 0.45 ± 0.08 logarithm of the minimum angle of resolution (logMAR) (0 to 2 logMAR). CONCLUSIONS: Several ocular complications with a decreased mean visual acuity were described in a young healthy population. In addition, patient information on the safety of this procedure appeared insufficient.

BACKGROUND/AIMS: To assess risk factors for serous retinal detachment (SRD) in the fellow eye of patients with central serous chorioretinopathy (CSC) based on clinical data and multimodal imaging findings, including baseline late-phase indocyanine green angiography (ICGA). METHODS: Consecutive patients with unilateral CSC were retrospectively assessed. Inclusion criteria were the availability of late-phase ICGA and a spectral-domain optical coherence tomography (OCT) macular cube for both eyes at baseline and over 3 months. Subsequent OCT of fellow eyes was reviewed to detect the development of SRD during the follow-up. Baseline medical data and multimodal imaging findings were analysed using Kaplan-Meier survival curves (log-rank test). RESULTS: Sixty-eight patients with unilateral CSC were included. An SRD was detected in 19% of fellow eyes during a mean follow-up of 25.8±18.7 months. Hyperfluorescent plaques on midphase ICGA, hypofluorescent foci on late-phase ICGA, retinal pigment epithelium changes on fundus autofluorescence and fluorescein angiography abnormalities were associated with the occurrence of SRD (log-rank test; p<0.001, p=0.02, p=0.002 and p=0.001, respectively). CONCLUSION: These results suggest that the fellow eyes with specific findings on multimodal imaging in patients with unilateral CSC should be carefully followed up for possible incidence of CSC.

Preclinical and clinical evidences show that aldosterone and/or mineralocorticoid receptor (MR) over-activation by glucocorticoids can be deleterious to the retina and to the retinal pigment epithelium (RPE)-choroid complex. However, the exact molecular mechanisms driving these effects remain poorly understood and pathological consequences of chronic exposure of the retina and RPE/choroid to aldosterone have not been completely explored. We aimed to decipher the transcriptomic regulation in the RPE-choroid complex in rats in response to acute intraocular aldosterone injection and to explore the consequences of systemic chronic aldosterone exposure on the morphology and the gene regulation in RPE/choroid in mice. High dose of aldosterone (100â¯nM) was intravitreously injected in Lewis rat eyes in order to yield an aldosterone dose able to induce a molecular response at the apical side of the RPE-choroid complex. The posterior segment morphology was evaluated in vivo using optical coherence tomography (OCT) before and 24â¯h after aldosterone injection. Rat RPE-choroid complexes were used for RNA sequencing and analysis. Uninephrectomy/aldosterone/salt (NAS) model was created in wild-type C57BL/6 mice. After 6 weeks, histology of mouse posterior segments were observed ex vivo. Gene expression in the RPE-choroid complex was analyzed using quantitative PCR. Acute intravitreous injection of aldosterone induced posterior segment inflammation observed on OCT. RNA sequencing of rat RPE-choroid complexes revealed up-regulation of pathways involved in inflammation, oxidative stress and RNA procession, and down-regulation of genes involved in synaptic activity, muscle contraction, cytoskeleton, cell junction and transporters. Chronic aldosterone/salt exposure in NAS model induces retinal edema, choroidal vasodilation and RPE cell dysfunction and migration. Quantitative PCR showed deregulation of genes involved in inflammatory response, oxidative stress, particularly the NOX pathway, angiogenesis and cell contractility. Both rodent models share some common phenotypes and molecular regulations in the RPE-choroid complex that could contribute to pachychoroid epitheliopathy in humans. The difference in inflammatory status relies on different intraocular or systemic route of aldosterone administration and on the different doses of aldosterone exposed to the RPE-choroid complex.

PURPOSE: To compare the shape of the capsulotomy, its change, and its impact on visual quality over 1 year using the femtosecond laser system from the manual technique. METHODS: In this two-center cross-sectional study from May 2012 to June 2013, each patient had femtosecond laser-assisted cataract surgery in one eye (FLACS group) and conventional phacoemulsification cataract surgery in the other eye (CPCS group). An evaluation of the capsulotomy was performed using retroillumination slit-lamp photographs at 7 days, 6 months, and 1 year after surgery. Effective lens position (ELP), refractive error, and corrected distance visual acuity (CDVA) were analyzed. RESULTS: Thirty-three patients were included in the study. Diameters of capsulorhexis were more precise and deviation surfaces were lower in the FLACS group than in the CPCS group at each evaluation (P < .05). Femtosecond laser capsulotomies were less modified over time than manual continuous curvilinear capsulorhexis. No significant differences were observed for CDVA, refractive error, and ELP between groups. CONCLUSIONS: More precise capsulotomy sizing can be achieved with the femtosecond laser compared to continuous curvilinear capsulorhexis. Femtosecond laser capsulotomies are less modified over time but did not improve ELP or visual quality. [J Refract Surg. 2017;33(1):44-49].

PURPOSE: To assess the safety of a laryngeal mask (i-gel) in keratoplasty performed under general anesthesia. METHODS: Patients with indications for keratoplasty (n = 110) were enrolled in a prospective study and randomly assigned to the i-gel (n = 55; 30 lamellar keratoplasty and 25 penetrating keratoplasty) or tracheal tube group (n = 55; 29 lamellar keratoplasty and 26 penetrating keratoplasty). Perioperative complications and the recovery time were compared between the 2 groups using the t test or χ(2) test. Contraindications to elective use of the laryngeal mask airway (esophageal reflux, extreme obesity, oropharyngeal pathology, or expected difficult intubation) and expected difficult intubation were excluded. RESULTS: No surgical perioperative complications were reported in either group. There was a significantly greater incidence of coughing at extubation and/or after extubation in the tracheal group (40/55; 73%) than in the laryngeal mask group (3/55; 5%) (P < 0.001). The recovery time was shorter in the i-gel group (80 minutes; 95% confidence interval, 75-86) compared with that in the tracheal tube group (88 minutes; 95% confidence interval, 82-95) (P = 0.03). There were no significant differences in the incidence of sore throat and hoarseness between both devices. CONCLUSIONS: The use of i-gel for keratoplasty under general anesthesia appears to be safe, reduces the risk of potential ocular hypertension during recovery, and saves recovery time.

PURPOSE: To determine the refractive efficacy, predictability, stability, and complication rate of Intralase femtosecond laser-assisted astigmatic keratotomy (AK) for irregular astigmatism after penetrating keratoplasty (PKP). SETTING: Ophthalmology Department, Hôtel-Dieu, Paris, France. DESIGN: Retrospective case series. METHODS: Femtosecond laser-assisted AK was performed to treat high irregular astigmatism (>5.0 diopters [D]) after PKP. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, manifest refraction, vector analysis, and complications were evaluated. RESULTS: The study evaluated 62 eyes of 57 patients over a mean follow-up of 28 months ± 3.5 (SD). Preoperatively, the mean CDVA was 0.51 ± 0.26 logMAR and the mean UDVA was 0.98 ± 0.24 logMAR; 6 months postoperatively, the mean CDVA and UDVA improved to 0.40 ± 0.22 logMAR and 0.60 ± 0.2 logMAR, respectively (both P < .01). The mean preoperative absolute astigmatism was 7.1 ± 1.72 D; 6 months postoperatively, the mean refractive astigmatism was 2.6 ± 2.4 D (P < .001). The UDVA, CDVA, and astigmatism remained stable up to the end of follow-up. The efficacy index was 0.81 at 6 months and 0.67 at 2 years. There were 2 cases of microperforation, 3 cases of infectious keratitis, 3 graft rejection episodes, and 1 case of endophthalmitis. Overcorrection occurred in 12 eyes. CONCLUSIONS: Femtosecond laser-assisted AK was effective in reducing irregular astigmatism after PKP. Predictability of astigmatism correction is variable over time with a decrease in the efficacy index 2 years postoperatively. Refinement of the treatment nomogram for femtosecond laser-assisted AK for high astigmatism after PKP remains a major issue.

We present a case report of a 60-year-old white woman, found to have advanced angle closure glaucoma in the right eye and appositional closure for about half of the left eye and no glaucoma. The remaining angle of the left eye was open with localized heavy pigmentation of the ciliary body band and trabecular meshwork. Ultrasound biomicroscopy showed a ciliary body tumor displacing the iris root centripetally preventing angle closure.

Our objective was to compare neutral red (NR) tests performed separately and on the same microplates as hydroethidine, H2DCF-DA and YO-PRO®-1 assays, and to compare toxicity ratios calculated with the two methods. Human trabecular meshwork cells (HTM-3) were exposed to different concentrations of benzalkonium chloride (BAC), to PBS and to diluted solutions of latanoprost and bimatoprost. Microplate fluorescence spectrophotometry assays were performed: NR uptake for cell viability evaluation, hydroethidine and H2DCF-DA for reactive oxygen species (ROS), and YO-PRO®-1 for apoptosis. The four NR assays presented identical toxicological profiles and correlation coefficients between them were close to one. There was no difference between toxicity ratios for ROS assays calculated by the two methods, with high correlation coefficients. However, in the apoptosis assay, ratios calculated with the double staining technique were more accurate. Thus, it is possible and recommended to perform NR assays on the same microplates as the other assays. This double staining procedure could constitute a quality control procedure and would allow multiparametric analysis.

PURPOSE: To correlate pterygium activity with in vivo confocal microscopy (IVCM) and ex vivo impression cytology (IC) analyses. METHODS: Twenty-eight pterygia from 16 patients were analyzed in this study. A pterygium activity score was obtained by summing four scores of ocular discomfort, pterygium hyperemia, keratitis, and the presence of Fuchs patches. Patients underwent pterygium IVCM analysis and collection of IC specimens on the pterygium. IC specimens were analyzed quantitatively by immunohistochemistry for goblet cell and dendritiform inflammatory cell density. IVCM images and IC results were compared to search for a possible correlation with the pterygium activity score. RESULTS: The presence of inflammatory cells, numerous blood vessels, and an irregular limit between the cornea and the pterygium with infiltration of hyperreflective cells in the adjacent corneal epithelium were the signs observed with IVCM associated with pterygium activity. Using IC, the density of goblet cells and dendritiform inflammatory cells was significantly correlated to the pterygium activity score (Spearman coefficient 0.765, P < 0.0001 and 0.799, P < 0.0001, respectively). In the same pterygium, dendritic inflammatory cell density and goblet cell density were also significantly correlated (Spearman coefficient 0.952; P < 0.0001). CONCLUSIONS: The correlation of pterygium cell changes with pterygium activity supports the role of inflammation and its relationship with goblet cells in the pathogenesis of pterygium.

PURPOSE: Dysthyroid Optic Neuropathy (DON) can lead to irreversible visual loss. We report risk features correlated with poor visual recovery despite an intensive treatment in a series of patients with DON. DESIGN: Retrospective analysis of a non-comparative interventional series. METHODS: Between 1997 and 2007, 300 consecutive patients with Graves' orbitopathy were seen at the Rothschild Foundation (Paris). Medical records of all consecutive patients who developed a DON were reviewed. Demographic, clinical features and visual function were collected at the time of the first onset, one month follow-up after medical and sometime surgical treatment and at the last examination. Statistical analysis (reflected as p values) gathered the significant observations into detrimental visual recovery prognostic factors for DON. RESULTS: Fifty-six eyes of 29 patients developed a DON. Sixteen eyes (28%) did not improve vision despite usual treatment (intravenous steroids and surgical decompression when necessary). An inferior altitudinal visual field defect (AVF, p=0.0004) and/or a lack of response to intravenous steroids boluses (p= 0.011) were related to a poor recovery. CONCLUSION: DON prognosis is highly variable. Our results suggest that a non-inflammatory element, probably vascular could be involved in atypical DONs. An earlier recognition could prompt to rapid surgical treatment for these patients.

A 65-year-old white man presented with sudden onset of painless decrease in vision and a red eye 5 days after cataract surgery. The visual acuity was 20/400 with mild injection. Marked iritis was present, and a hypopyon could be seen behind the intraocular lens (IOL) in the capsular bag. The posterior segment was clear. The iritis worsened despite 4 days of hourly topical corticosteroid treatment. Anterior chamber washout was performed, with clearing of the material behind the IOL. The iritis subsided 4 weeks later, and visual acuity recovered to 20/20. Capsular block syndrome can present as phacoanaphylactic endophthalmitis if cortical material is left in the capsular bag, requiring surgical intervention.
