Predisposing factors, clinical and microbiological insights of bacterial keratitis: analysis of 354 cases from a leading French academic centre.

AIMS: To report an epidemiological update of bacterial keratitis (BK) in a tertiary ophthalmology centre over 20 months compared with a previous study on the same timeframe from 1998 to 1999. METHODS: 354 patients with BK documented by microbiological corneal scraping or resolutive under antibiotics treatment from January 2020 to September 2021 were analysed retrospectively. RESULTS: One or several risk factors were found in 95.2% of patients: contact lens wear (45.2%), ocular surface disease (25.0%), systemic disease (21.8%), ocular trauma (11.9%) and ocular surgery (8.8%). The positivity rate of corneal scrapings was 82.5%, with 18.2% polybacterial. One hundred seventy-five (59.9%) bacteria were Gram-negative, and 117 (40.1%) were Gram-positive. The most common bacteria were Pseudomonas aeruginosa (32.5%), Moraxella spp (18.1%) and Staphylococcus aureus (8.2%). Final visual acuity (logarithm of the minimum angle of resolution) was associated with age (r=+0.48; p=0.0001), infiltrate size (r=+0.32; p<0.0001), ocular surface disease (r=+0.13; p=0.03), ocular trauma (r=-0.14; p=0.02) and contact lens wear (r=-0.26; p<0.0001). Gram-negative bacteria were responsible for deeper (r=+0.18; p=0.004) and more extensive infiltrates (r=+0.18; p=0.004) in younger patients (r=-0.19; p=0.003). Compared with the previous period, the positivity rate of corneal scrapings and the proportion of Gram-negative bacteria, especially Moraxella spp, increased. All P. aeruginosa and Moraxella spp were sensitive to quinolones, and all S. aureus were sensitive to both quinolones and methicillin. CONCLUSION: Contact lens wear remained the leading risk factor. The bacteria distribution was reversed, with a predominance of Gram-negative bacteria and increased Moraxella spp.

Comparison of optical aberrations in keratoconus with scleral versus rigid gas permeable lenses.

PURPOSE: to assess optical aberrations under scleral (SL) versus rigid gas permeable (RGP) lenses in patients with keratoconus. METHODS: A prospective study including 25 eyes of 14 patients. The best-corrected visual acuity (BCVA) with corrective glasses, RGP and SL, stage of keratoconus (Amsler-Krumeich classification), minimum pachymetry, maximum keratometry, and corneal higher-order aberrations (i.e, total HOAs, coma, and trefoil) with RGP and with SL were collected. Aberrometry was performed using iTrace® aberrometer (Tracey Technologies, USA). RESULTS: 80% of the included keratoconus patients were stage 4, with a mean age of 34.3 years (±8.8). There were no significant differences in mean BCVA (logMAR) between SL and RGP. The mean BCVAs were significantly better both with SL (p < 0.0001) and RGP (p < 0.0001) compared with corrective glasses. Total HOAs (p = 0.01), coma (p = 0.003) and trefoil (p = 0.008) were significantly lower with SL compared with RGP. The BCVA decreased with the stage of keratoconus in SL (p = 0.01) and RGP (p = 0.02). The BCVA decreased with decreasing minimum pachymetry in SL (p = 0.02) and RGP (p = 0.002), and with increasing maximum keratometry in SL (p = 0.02) and RGP (p = 0.01). Significant correlations were found between BCVA, total HOAs (p = 0.008), and coma (p = 0.02) in SL. CONCLUSION: For the same keratoconus patients, total higher order, coma and trefoil optical aberrations were reduced with scleral lenses compared to rigid gas permeable lenses.

Freeze-dried amniotic membrane graft with a spongy layer in bilateral peripheral ulcerative keratitis: a case report.

BACKGROUND: Peripheral ulcerative keratitis (PUK) is a group of inflammatory corneal ulcers with stromal thinning and peripheral localization. Amniotic membranes (AM) are used for their anti-inflammatory and healing properties. A freeze-drying process now allows maintaining the AM viable for a long time at room temperature without altering its physical, biological, and morphologic characteristics. The effectiveness of spongy freeze-dried amniotic membrane (FD-AM) graft with multimodal imaging in the management of severe corneal thinning PUK has not been reported. CASE PRESENTATION: A 67-year-old Caribbean man histologically diagnosed with ulcerative colitis, was referred to our tertiary eye care center for a deep nasal juxtalimbal ulcer of the left eye. He was treated with topical steroids and antibiotics, methylprednisolone pulses, and oral prednisone. Due to continuous stromal thinning with 100 µm of residual corneal thickness, the decision was made to perform surgery. Conjunctival resection, inlay and overlay spongy FD-AM (Visio Amtrix® S, Tissue Bank of France, FR) were performed to preserve globe integrity. Despite tapering off oral steroids, PUK developed in the fellow eye on the 2 months follow-up. Treatment with human monoclonal antibody against tumor necrosis factor-alpha was initiated to control the active underlying inflammation. Six months following surgery, the ulcer was healed and corneal thickness in front of the former ulceration was measured at 525 µm on anterior segment-optical coherence tomography. Confocal microscopy confirmed the integration of the amniotic membrane between the corneal epithelium and the anterior stroma. CONCLUSION: Transplantation of FD-AM with a spongy layer was associated with restoration of normal corneal thickness in the PUK area. It seems to be a safe, effective, and easily accessible solution for the surgical management of PUK with impending perforation.

EYERUBBICS: The Eye Rubbing Cycle Study.

Purpose: Describe the cognitive and behavioral symptomatology of patients with chronic ocular rubbing in keratoconus (KC) and Ocular Surface Disease (OSD) using a self-questionnaire. Methods: A prospective study was conducted in a tertiary ophthalmology center between May and July 2021. We consecutively included all patients presenting with one of the following conditions: KC and OSD. A questionnaire including the evaluation of Goodman and CAGE-modified criteria for eye rubbing was given to patients in consultation to evaluate their ocular symptoms and medical background. Results: We included 153 patients in the study. Of these, 125 (81.7%) patients reported eye rubbing. The average Goodman score was 5.8 ± 3.1 and was ≥ 5 in 63.2% of cases. The CAGE score was ≥ 2 in 74.4% of patients. Addiction (p = 0.045) and psychiatric family history (p = 0.03) were more frequent in patients with higher scores. Ocular symptoms and eye rubbing were significantly more frequent and intense in patients with higher scores; Conclusion: Eye rubbing presents addictive-like cognitive and behavioral characteristics in patients with KC or OSD. The eye rubbing cycle could play an essential role in the onset and progression of keratoconus and could be a factor in the maintenance of dry eye.

Review of glaucoma management in France.

PURPOSE: To conduct a review of glaucoma management in France. METHOD: A 15-question survey was sent to ophthalmologists listed in the journal Réalités Ophtalmologiques and the Syndicat National des Ophtalmologues de France. RESULTS: 459/471 responses were analyzed. Gonioscopy was performed by 64.7% of respondents with a Goldmann three-mirror lens, by 51.4% with a four-mirror lens, and 8.2% preferred to perform the procedure with anterior segment imaging. The visual field was reported to be interpreted without difficulty by 87.8% of the practitioners, and 54.0% utilize a progression software. Ultrasound biomicroscopy was reported to be interpreted without difficulty by 20.0% of practitioners. In cases of severe ocular hypertonia with flat bleb in early postoperative trabeculectomy, 61.7% chose ocular massage as a first-line treatment, 52.9% chose laser suture lysis, 50.5% utilized needling, and 24.8% employed hypotonizing eyedrops. In case of severe ocular hypertonia with flat bleb in early postoperative deep sclerectomy, 53.2% chose goniopuncture as their first treatment, 34.4% employed needling, 31.8% utilized ocular massage, and 23.3% chose hypotonizing eyedrops. The selective laser trabeculoplasty is used as soon as the diagnosis is made by 37.5%, in association with a mono or dual therapy by 93.2%, after trying different combinations of eyedrops by 45.5%, when the visual field deteriorates despite a normalized intraocular pressure by 46.6%, and in cases of hypertonia after filtering surgery by 19.2%. Concerning management for primary angle-closure glaucoma, 80.8% considered peripheral iridotomy, and 18.7% utilized cataract surgery. CONCLUSION: The diversity of responses concerning glaucoma management should draw attention to the need for standardized practices.

Intraocular Lens Calcification After Pseudophakic Endothelial Keratoplasty.

PURPOSE: To determine the incidence and to document risk factors for intraocular lens (IOL) calcification after pseudophakic endothelial keratoplasty. METHODS: We retrospectively studied 2700 consecutive penetrating, anterior lamellar and endothelial keratoplasties carried out between December 1992 and June 2022 at the National Eye Hospital, Paris, France. DESIGN: Retrospective cohort study. RESULTS: All IOL calcification cases were associated with endothelial keratoplasty. Out of 588 endothelial keratoplasty procedures, 576 eyes were pseudophakic at the end of surgery. Fourteen cases of IOL calcification were observed during follow-up. The cumulative incidence of IOL calcification after endothelial keratoplasty was 4.5%±1.3% at 60 months. Hydrophilic acrylic IOL material (P < .001) and use of SF6 for anterior chamber tamponade (P = .001) were significantly and independently associated with the cumulative incidence of IOL calcification. CONCLUSION: The incidence of IOL calcifications seems to be around 5%. Ophthalmologists should avoid hydrophilic acrylic IOLs in patients with endothelial disorders. When the patient already has a hydrophilic IOL, SF6 should be avoided. The only effective treatment is IOL exchange.

Corneal Epithelial Thickness Mapping in the Diagnosis of Ocular Surface Disorders Involving the Corneal Epithelium: A Comparative Study.

PURPOSE: The purpose of this study was to analyze the role of corneal epithelial thickness (ET) mapping provided by spectral domain optical coherence tomography in the diagnosis of ocular surface disorders (OSDs) involving the corneal epithelium. DESIGN: This was a retrospective comparative study. METHODS: Institutional settings are as follows. Study population includes 303 eyes with an OSD and 55 normal eyes (controls). Observation procedures include spectral domain optical coherence tomography with epithelial mapping in the central 6 mm. Main outcome measures include ET map classification (normal, doughnut, spoke-wheel, localized/diffuse, and thinning/thickening patterns) and ET data and statistics (minimum, maximum, and SD). A quantitative threshold was determined with receiver operating curves to distinguish pathological from normal corneas. Sensitivity and specificity of classification and quantitative data were calculated using all eyes to assess the ability to distinguish corneas with a given corneal disorder from other conditions. RESULTS: Classification of full agreement between 3 readers was obtained in 75.4% to 99.4% of cases. Main OSD features were keratoconus (135 eyes), doughnut pattern (sensitivity/specificity = 56/94%), and max-min ET ≥ 13 µm (84/43%); limbal deficiency (56 eyes), spoke-wheel pattern (66/98%), and max-min ET ≥ 14 µm (91/59%); epithelial basement membrane dystrophy (55 eyes), inferior thickening pattern (55/92%), and central ET > 56 µm (53/81%); dry eye (21 eyes), superior thinning pattern (67/88%), and minimal ET ≤ 44 µm (86/48%); pterygium (10 eyes), nasal thickening pattern (100/86%), and nasal ET > 56 µm (80/71%); and in situ carcinoma (11 eyes), max ET > 60 µm (91/60%), and ET SD >5 µm (100/58%). CONCLUSIONS: The epithelial map pattern recognition combined with quantitative analysis of ET is relevant for the diagnosis of OSDs and for distinguishing various OSDs from each other. Deep learning analysis of big data could lead to the fully automated diagnosis of these disorders.

Anterior chamber tap cytology in acute postoperative endophthalmitis: a case-control study.

AIMS: To determine anterior chamber tap cytology characteristics in acute postoperative bacterial endophthalmitis. METHODS: 488 eyes of 488 patients were included in this retrospective case-control study. The study group included 93 eyes with bacteriologically documented endophthalmitis and 85 eyes with clinical endophthalmitis. The control group included 33 eyes with non-infectious postoperative inflammation, 116 eyes with acute uveitis and 161 cataract surgery eyes with no ocular inflammation. Cytological analysis, direct examination and microbiological cultures were performed in aqueous humour (AqH) samples. Inclusion criteria for the study group were the following: suspected endophthalmitis within 30 days following cataract surgery by phacoemulsification, secondary lens implantation, pars plana vitrectomy or intravitreal injection; best-corrected visual acuity (BCVA) <20/400; hypopyon or cyclitic membrane; absence of visibility of the retina; vitritis at a slit-lamp examination or in ultrasound B-scan. RESULTS: Cell line counts (mainly polymorphonuclear neutrophils) were significantly higher in the two endophthalmitis study subgroups than in the three control subgroups. The study group showed a predominance of polymorphonuclear neutrophils as opposed to the three control subgroups including uveitis (p<0.00001). The best sensitivity/specificity was obtained using a polymorphonuclear neutrophil threshold of 10 per field (sensitivity, 0.90; specificity, 0.75). The sensitivity of the bacterial culture was 32% in the AqH. High neutrophil count was associated with poorer initial BCVA (rs=0.62; p<0.00001) and higher risk of retinal detachment during (p=0.04) and after (p<0.001) hospitalisation. CONCLUSION: Anterior chamber tap cytology is a quick and accessible tool complementary to culture and PCR for the management of acute postoperative endophthalmitis.

Update on fungal keratitis in France: a case-control study.

PURPOSE: To report an epidemiological update of documented fungal keratitis (FK) in a French tertiary ophthalmological centre from 2014 to 2018 in comparison with a previous period from 1993 to 2008. METHODS: Sixty-two consecutive FK documented by microbiological corneal scrapings were compared with the 64 FK of the previous study. Amphotericin B and voriconazole eye drops were administered hourly. Population characteristics, clinical findings, aetiological organisms and treatments were analysed. RESULTS: The most frequently identified fungi were Fusarium (61%), Aspergillus (6.5%) and Candida (5%). Thirty out of 44 cases examined with in vivo confocal microscopy (IVCM) presented filaments. Ten required conventional cross-linking, 9 therapeutic penetrating keratoplasty, and 2 enucleation. Risk factors significantly associated with the absence of response to medical treatment were patient age (p = 0.01), presence of a deep stromal infiltrate at presentation (p = 0.04) and high numbers of filaments in IVCM images (p = 0.01). The two populations were comparable in age, but not in sex ratio males/females (18/44 versus 37/26 in the previous study; p = 0.001). The frequency of contact lens-associated infection increased from 35.5% to 71% (p = 0.0001) between the two periods. Since then, filamentous FK increased from 69% (44/64) to 95% (59/62) (p = 0.0001). A history of keratoplasty was less frequently reported during the last period (3.2% (2/62) versus 17% (11/64) of cases (p = 0.01)). A clear decrease in the frequency of therapeutic keratoplasty was noted from 39% (25/64) to 14% (9/62) (p = 0.02). CONCLUSION: The frequency of filamentous keratomycosis is currently increasing. Elderly patients and the presence of numerous filaments in IVCM are associated with poor clinical outcomes.

Freeze-Dried Versus Cryopreserved Amniotic Membranes in Corneal Ulcers Treated by Overlay Transplantation: A Case-Control Study.

PURPOSE: The purpose of this study was to assess cryopreserved amniotic membrane (C-AM) versus chorion-free freeze-dried amniotic membrane (FD-AM) overlay transplantation for corneal ulcers in a French tertiary ophthalmology hospital. METHODS: Between March and July 2020, when C-AMs were not available because of the COVID-19 pandemic, 28 corneal ulcers underwent FD-AM overlay transplantation and were retrospectively compared with 22 corneal ulcers treated with C-AM during the same period in 2018. All patients had at least 3 months of follow-up, and those who underwent combined surgeries were excluded. Ulcers were assessed at baseline and then at 72 hours, 1 month, and 3 months. Population demographics, follow-up time, ulcer etiologies, epithelial defect size, ulcer depth, and complications were also recorded. RESULTS: Baseline characteristics and clinical features of both groups were comparable. There was no statistically significant difference in the number of overlay AM transplantations (P = 0.52) or early detachments (P = 0.57). At 3 months, the corneal healing rate was almost the same in both groups (89% and 91% for FD-AM and C-AM, respectively; P = 0.87). Complications were equally uncommon (11% and 9%, respectively; P = 0.92). In logistic regression, the type of the membrane did not influence corneal healing at 1 month (P = 0.42) or 3 months (P = 0.99), regardless of the depth of the ulcer. However, whatever the type of AM used, the deeper the ulcer was, the less likely it was to heal at 3 months (P = 0.02). CONCLUSIONS: This is the first study that provides positive insight into the effectiveness of FD-AM compared with C-AM when used as overlay transplantation for treating corneal ulcers.

Long-Term Results and Refractive Error After Cataract Surgery With a Scleral Incision in Eyes With Deep Anterior Lamellar Keratoplasty.

PURPOSE: Phacoemulsification in eyes with deep anterior lamellar keratoplasty (DALK) is associated with possible decreased graft survival and difficult IOL power calculation. We assessed cataract surgery in eyes with previous DALK. METHODS: Thirty-three consecutive eyes with DALK and further phacoemulsification with scleral incision were included in this retrospective study. At each postoperative visit, eyes were assessed with manifest refraction, optical coherence tomography, specular corneal topography, and noncontact wide-field specular microscopy. RESULTS: The average postkeratoplasty follow-up time was 102 months [95%-CI, (85-119)]. Cataract surgery was performed on average 43 months (30-56) after DALK. The average postphacoemulsification follow-up time was 58 months [42-74]. All grafts remained clear during follow-up. The best spectacle-corrected logarithm of the minimum angle of resolution visual acuity improved by 2.5 lines [1.8-3.1] on average after cataract surgery from 0.58 (20/77) to 0.34 (20/44) (P < 0.001). The spherical equivalent and intraocular pressure significantly improved from -4.1 D to -1.7 D and from 15.9 to 14.0 mm Hg, respectively. The corneal central thickness was not significantly modified, and the endothelial density decreased by 5.3% from 2081 to 1970 cells/mm2 (P = 0.003). The minimal difference between the achieved and predicted spherical equivalents [-0.05 D, (-2.33; +2.21)] was obtained with the Hoffer Q formula using the IOLMaster axial length and the Orbscan keratometry. CONCLUSIONS: Patients with DALK who underwent phacoemulsification with a scleral incision had a satisfying residual refractive error, very high graft survival, and very few complications. The Hoffer Q formula with the IOLMaster axial length and the specular corneal topography keratometry seems to be the most accurate for IOL calculation.

Prevention of infection after corneal refractive surgery: a French survey.

PURPOSE: To report the French refractive surgeons' real-life practices for preventing infection after corneal refractive surgery (photorefractive keratotomy [PRK], laser in situ keratomileusis [LASIK], and small-incision lenticule extraction). SETTING: France. DESIGN: Anonymous practice survey. METHODS: The questionnaire was sent in a single email invitation to 400 declared refractive surgeons. The following information was recorded between December 2019 and April 2020, before the coronavirus pandemic: demographics data, preoperative evaluation and preparation of the patient, surgical management, immediate and postoperative protocol, and infections reported after corneal refractive surgery. RESULTS: Eighty-three of 400 surgeons (20.75%) responded to the questionnaire; 55 (66.0%) performed more than 50 corneal refractive surgeries a year, and 25 (30.1%) performed more than 200 procedures a year. Thirty-six (43.4%) surgeons wore 3 protective items, 37 (44.6%) 2, 5 (6.0%) 1, and 5 (6.0%) zero. Seventy-seven (92.8%) surgeons used povidone-iodine for skin area disinfection and 54 (65%) for conjunctival fornix disinfection. The contact time of povidone-iodine was less than 3 minutes for 71 (85.0%) surgeons. Twenty surgeons (24.1%) reported at least 1 postrefractive surgery infection. Twenty percent of surgeons who wore sterile gloves for PRK reported postoperative infections compared with 62.5% for those who did not (P = .008). These figures were, respectively, 8.7% and 66.7% for the use of sterile gloves during LASIK (P = .002); 8.9% of surgeons who wore surgical masks for LASIK reported postoperative infections compared with 50.0% for those who did not (P = .01). CONCLUSIONS: Practices are variable among French refractive surgeons. Wearing a surgical mask and sterile gloves during corneal refractive surgery appears to be advisable.

Contact lens induced bacterial keratitis in LCD II: Management and multimodal imaging: a case report and review of literature.

PURPOSE: To describe the management and multimodal imaging of lattice corneal dystrophy type II (LCD-II) complicated by an infectious keratitis due to a bandage contact lens and to review current literature. OBSERVATION: A 50-year-old female was diagnosed with Meretoja's Syndrome by the triad of facial palsy, loose skin (cutix laxa), and stromal corneal dystrophy. At slit lamp, bilateral lattice corneal dystrophy (LCD) was characterized by multiple linear refractile lines and subepithelial fibrosis along with Neurotrophic keratitis Mackie grade I. Findings of anterior segment optical coherence tomography (AS-OCT) were epithelial irregularity, subepithelial fibrosis, hyperreflectivity on anterior stromal layer, lobulated stromal surface. In vivo confocal microscopy (IVCM) showed hyperreflected deposits on the basal and Bowman layers, visible keratocytes; fine lines and streaks between corneal lamella. The sub-basal nerve plexus and the stromal nerves were no longer visible. She presented in emergency with a left red eye. A severe bacterial keratitis was diagnosed as a complication of a bandage contact lens used to treat recurrent epithelial erosion. Corneal anesthesia was complete. Corneal neovascularization was evident 10 weeks later and topical bevacizumab (5 mg/ml) was introduced twice daily. Partial regression of deep stromal vessels was noticed at 3 months. CONCLUSION: In Meretoja's syndrome, neurotrophic keratopathy secondary to polyneuropathy due to systemic amyloid deposits is present in the advanced stages, promotes recurrent corneal erosions. Corneal sensitivity test, AS-OCT and IVCM are crucial in the diagnosis behind any recurrent corneal erosion. The use of bandage contact lens should be avoided in Meretoja's syndrome to prevent a possible infectious keratitis.

Assessment of Confocal Microscopy for the Diagnosis of Polymerase Chain Reaction-Positive Acanthamoeba Keratitis: A Case-Control Study.

PURPOSE: To determine in vivo confocal microscopy diagnostic criteria to diagnose Acanthamoeba keratitis (AK) using polymerase chain reaction (PCR) as the reference diagnostic technique. DESIGN: Retrospective case-control study. Data were recorded prospectively and analyzed retrospectively. PARTICIPANTS: Fifty patients with PCR-positive AK (study group) and 50 patients with bacterial, fungal, viral, or immune keratitis featuring negative Acanthamoeba PCR results (control group). METHODS: In vivo confocal microscopy performed at the acute stage of keratitis. MAIN OUTCOME MEASURES: Presence of in vivo confocal microscopy images suggestive of AK. Multivariate logistic regression was used to determine the relationship between types of images and presence of PCR-positive AK. RESULTS: The following 4 types of images were associated significantly with PCR-positive AK (P < 0.05): bright spots (round or ovoid hyperreflective objects with no double wall; diameter, <30 µm); target images (hyperreflective objects with hyporeflective halo; diameter, <30 µm); clusters of hyperreflective objects (diameter, <30 µm); and trophozoite-like objects (diameter, >30 µm). Specificity of both target and trophozoite images was 100%. This figure was 98.2% for clusters and 48.2% for bright spots. If the diagnosis of AK was made on presence of target images, clusters or trophozoite images (at least 1 of the 3 features), the positive predictive value of confocal microscopy was 87.5% and the negative predictive value was 58.5%. CONCLUSIONS: Acanthamoeba keratitis is a serious vision-threatening disease. In vivo confocal microscopy can help in this challenging diagnosis, especially when PCR is delayed, shows negative results, or is not available. Target images and trophozoite-like images are pathognomonic of AK. Clusters of hyperreflective objects are highly specific of AK. However, the overall sensitivity of in vivo confocal microscopy features of AK is low. In addition to the clinical features, microbiological tests (direct examination and cultures of corneal scrapings), and PCR, in vivo confocal microscopy allows for more rapid diagnosis and treatment initiation, potentially leading to an improved outcome.

Visual Acuity in Birdshot Retinochoroidopathy Evaluation.

PURPOSE: To determine the statistical correlation between visual acuity (VA) and various quantitative parameters relevant to birdshot retinochoroidopathy (BRC) evaluation. DESIGN: Hospital-based retrospective observational study. METHODS: setting: Institutional. STUDY POPULATION: Consecutive HLA29+ BRC patients were included between May and August 2013 at a single tertiary center (Pitié-Salpétrière Hospital, Paris). OBSERVATION PROCEDURES: Demographic data and quantitative parameters relevant to BRC at baseline were collected: VA, degree of anterior and posterior inflammatory reaction, foveal thickness measured by optical coherence tomography (OCT), Arden ratio, and electrooculography (EOG) light peak. MAIN OUTCOME MEASURES: Correlation between VA and the other parameters of the ipsilateral and fellow eye was performed using Spearman rank correlation coefficients. RESULTS: Fifty-five patients were included. Mean VA was 6/9.5 in the right eye (OD) and 6/12 in the left eye (OS). Mean foveal thickness was 240 µm OD (range: 112-606) and 251 µm OS (range: 85-662). Mean Arden ratio was 159% OD and 160% OS. EOG light peak was 714 mV OD (range: 316-1379) and 746 mV OS (range: 272-1652). VA of a given eye was moderately correlated with VA of the contralateral eye (r = 0.4). On the contrary, all other parameters showed a strong correlation between both eyes (all r > 0.7, P < .01). Overall, none of the studied parameters was correlated with its VA (all r < 0.5). CONCLUSION: In BRC, visual acuity alone does not seem to fully reflect the disease severity in terms of clinical or ancillary quantitative findings at baseline.

Successful use of infliximab therapy in sight-threatening corticosteroid-resistant Vogt-Koyanagi-Harada disease.

PURPOSE: To report an experience with infliximab in severe corticosteroid-resistant Vogt-Koyanagi-Harada (VKH) disease. DESIGN: Interventional case series. METHODS: The medical records of 2 adult patients were reviewed. RESULTS: Both patients had a visual acuity reduced to hand motion perception bilaterally after 1 month of high-dose corticosteroid therapy, due to multiple exudative retinal detachment involving the fovea. Visual acuity and OCT findings improved immediately after the first infliximab infusion, retinal detachments fully resolved after 1 month and visual acuity returned to normal within 6 months. Despite a negative pretreatment screening, one patient developed multivisceral tuberculosis, which led to infliximab discontinuation after the 7th infusion and was cured by a 9-month ambulatory antibiotic regimen. The other patient received 11 well-tolerated infliximab infusions. Respectively, 9 and 4 months after infliximab discontinuation both patients had normal vision and OCT findings. CONCLUSION: Infliximab showed tremendous therapeutic efficacy in sight-threatening corticosteroid-resistant VKH disease.
