RESUMEN
PURPOSE: Analyze the influence of risk factors at presentation in the long-term immunosuppressive therapy (IMT) outcomes of ocular mucous membrane pemphigoid (OMMP). DESIGN: Retrospective multicenter study. PARTICIPANTS: Patients with OMMP seen at the Duke Eye Center, Tecnologico de Monterrey, and Hospital Clinic of Barcelona from 1990 to 2022. METHODS: Data at presentation on demographics, direct immunofluorescence, ocular findings, sites of extraocular manifestations (EOMs), and previous treatments in patients with a clinical or laboratory diagnosis of OMMP, were analyzed with multivariable analysis and Kaplan-Meier plots to identify factors associated with adverse outcomes. MAIN OUTCOME MEASURES: (1) Inflammatory control (no conjunctival inflammation in both eyes at 3 months on IMT); (2) relapse (new-onset inflammation after absolute control in either eye); (3) progression (≥ 1 cicatrizing stage progression in either eye); and (4) vision loss (≥ 2 Snellen lines). RESULTS: A total of 117 patients (234 eyes), 61% (71/117) of whom were women, with a mean age of 66.6 (SD: 12.4) years (range: 37-97 years) and median follow-up of 34 months (interquartile range: 16-66 months; range: 3-265 months), were enrolled. Inflammatory control was achieved in 57% of patients (67/117), with high-risk EOM (HR-EOM), including esophageal, nasopharyngeal, and/or genital involvement (adjusted odds ratio [aOR]: 12.51; 95% confidence interval [CI]: 2.61-59.99; P = 0.002) and corneal scarring (aOR: 3.06; 95% CI, 1.15-8.14; P = 0.025), as significant risk factors for persistent inflammation. Disease relapse, progression, and vision loss occurred in 20% of patients (23/117), 12% of patients (14/117), and 27% of patients (32/117), respectively. Baseline corneal scarring was a risk factor for relapse (adjusted hazard ratio: 4.14; 95% CI: 1.61-10.62; P = 0.003), progression (aOR: 11.46; 95% CI: 1.78-73.75; P = 0.010), and vision loss (aOR: 3.51; 95% CI: 1.35-9.10; P = 0.010). HR-EOM was associated with stage progression (aOR, 34.57; 95% CI, 6.57-181.89; P<0.001) and vision loss (aOR, 8.42; 95% CI, 2.50-28.42; P = 0.001). No significant differences were found between IMT regimes and relapse (P = 0.169). CONCLUSIONS: Ocular mucous membrane pemphigoid presenting with HR-EOMs and corneal scarring has an increased risk of stage progression and vision loss. Corneal scarring and severe inflammation at baseline were associated with an increased risk of relapse. A disease progression staging system incorporating both the HR-EOMs and corneal involvement is required to predict the visual outcome of OMMP better.

PURPOSE: Actinic conjunctivitis (AC), along with cheilitis (AChe), is part of the clinical spectrum of actinic prurigo (AP), a rare photo dermatosis that affects high-risk populations. We analyzed the clinical manifestations and onset of actinic conjunctivitis (AC), and its relationship with prurigo (AP) in a susceptible population. METHODS: This prospective observational cohort study was performed on Indigenous populations from the highlands of Chiapas, Mexico. Thorough dermatological and ophthalmological examinations were performed in patients attending a primary health care center. The clinical features, labor and environmental factors, onset timing, and clinical staging of AC and AP were analyzed. RESULTS: Of the 2913 patients studied, 54 patients (108 eyes) (1.8%) had AC, and 14 patients (25.9%) had AP. The mean age at diagnosis was 36.18 ± 18.52 years (6-70 years). The mean residential altitude was 1884 ± 434.2 m above sea level. Mean self-reported sun exposure was 5.14 ± 3.1 h a day (0.5-12 h). A total of 90.7% reported exposure to biomass fuels during cooking, and 50% to farm animals. AC was the sole manifestation in 70% of the cases. All patients had nasal and temporal photo-exposed conjunctiva. Among the eyes, 12.9% were classified as stage-1, 64.8% as stage-2, and 22.2% stage-3. A total of 83.3% of the patients had hyperpigmented lesions, and 35.1% had evaporative dry eye disease. CONCLUSIONS: AC may be the initial or sole manifestation of AP. Most AC cases (87%) were initially observed at the advanced stages of the disease. Although solar exposure was not associated with late AC stages, a positive association was found with farm animal exposure. Evaporative dry eye associated with meibomian gland dysfunction has not been previously reported in patients with AC.

PURPOSE: To analyze higher-order aberrations (HOAs) and their visual impact in a pediatric blepharokeratoconjunctivitis (PBKC) cohort compared with healthy controls. METHODS: Prospective case-control study of pediatric patients (≤ 16 years old). Subjects underwent wavefront aberrometry analysis to compare HOAs and their impact on visual quality. RESULTS: A total of 150 eyes from 76 patients were included in the analysis. The PBKC group consisted of 50 eyes and the control group of 100 healthy eyes. Mean age was 10.39 ± 3.81 years for the PBKC group and 10.80 ± 3.61 years for the controls. Mean corrected-distance visual acuity (CDVA) was 0.24 ± 0.21 logMAR in the PBKC group and 0.07 ± 0.1 in the controls (P < 0.001). Mean astigmatism was 1.6 ± 1.98D in the PBKC group vs. 0.67 ± 0.76D in the control group (P = 0.01). Mean RMS of HOAs was 1.05 ± 1.7mm in the PBKC group and 0.41 ± 0.18mm in the controls (P < 0.001). The mean modulation transfer function (MTF) in the PBKC group was significantly lower (16.37 ± 16.32) than controls (30.3 ± 23.57) (P < 0.001). Corneal leukomas, stromal vascularization, peripheral nummular subepithelial scars, and pannus formation are associated with increased HOAs. CONCLUSIONS: There was a significant increase in total HOAs of eyes with PBKC compared to healthy controls. Corneal opacity, vascularization, and scarring are associated with increased HOAs. The PBKC eye aberration profile: coma, secondary astigmatism, quadrafoil, and pentafoil, were associated with decreased CDVA and visual quality (PSF and MTF).

PURPOSE: To compare the visual, refractive, and topographic outcomes of a high irradiance accelerated corneal crosslinking (ACXL) protocol after a 12-month follow-up between pediatric and adult patients with progressive keratoconus (KC). METHODS: Retrospective, comparative, cohort study. Patients with KC were divided into two groups: pediatric (≤ 18 years) and adult (> 18 years). All of them were managed with epi-OFF ACXL (30 mW/cm2, 8 min, pulsed 1:1 on and off = 7.2 J/cm2). Visual, refractive, and topographic values were measured preoperatively and at 1, 3, 6, and 12 months postoperative. KC progression, defined as a Kmax increase of ≥ 1D during follow-up, was recorded. RESULTS: Eighty-nine eyes (53 patients) were included for analysis; 45 (50.6%) eyes were from pediatric patients and 44 (49.4%) from adults. At one-year follow-up, pediatric patients experienced significantly higher rates of progression (22.2% vs. 4.5%, p = .014). Contrariwise, female gender (Beta = - 3.62, p = .018), a baseline uncorrected visual acuity of Snellen ≥ 20/60 (Beta = - 5.96, p = .007), and being ≥ 15 years at ACXL treatment (Beta = - 0.31, p = .021) were associated with non-progressive disease. A significant improvement in best-corrected visual acuity, Kmin, Km, and Kmax was recorded in both groups. Overall, 86.5% of eyes from both groups showed Kmax stabilization or improvement. CONCLUSIONS: Despite the similarity in visual, refractive, and topographic outcomes in both groups, younger age was associated with KC progression after ACXL at one year of follow-up.

PURPOSE: Prostaglandin analogs (PGAs) are first-line treatments for ocular hypertension (OHT) and open-angle glaucoma (OAG). However, frequent side effects and high costs hinder patient's compliance resulting in disease progression. Evidence suggests selective laser trabeculoplasty (SLT) may be considered a first-line treatment for OHT and OAG due to its safety profile, minor side effects, and reduced costs. Considering that PGAs and SLT share action mechanisms, it is hypothesized that previous PGA therapy may affect subsequent SLT efficacy. Therefore, we analyzed if PGAs reduce SLT efficacy. METHODS: An evidence-based review was performed to assess the safety and efficacy of SLT in patients previously treated with PGAs. For this purpose, we performed an extensive literature search using the National Library of Medicine's PubMed and Google Scholar database for all English language articles published until May 2021. RESULTS: There is evidence of non-superiority of PGAs therapy versus SLT for OHT and OAG. A multicenter, randomized, observer-masked clinical trial (RCT) of untreated OHT and OAG patients concluded that SLT should be offered as the first-line treatment for these patients. This study was supported by a meta-analysis of RCTs, comparing SLT efficacy versus antiglaucoma drugs only, with the advantage of an SLT lower rate of adverse effects. CONCLUSIONS: Cost-effectiveness, patient compliance, and antiglaucoma drugs' side effects, including higher surgical failure, favor consideration of SLT as first-line therapy for OAG and OHT. Furthermore, SLT efficacy does not seem to be affected by prior PGA administration; however, larger cohort, comparative, multicenter RCTs are necessary to answer this question.

Dermatomyositis (DM) and polymyositis (PM) are idiopathic inflammatory myopathies characterized by progressive, symmetric, mainly proximal muscle weakness. DM is also characterized by cutaneous involvement. However, other clinical features, systemic involvement, histopathological findings, response to treatment, and prognosis, differ significantly. Although uncommon, ocular manifestations in DM and PM may potentially affect any structure within the eye. Notwithstanding being generally mild, ocular involvement in DM and PM may result in significant morbidity. Left untreated, significant retinal inflammation associated with hemorrhage and detachment may occur, leading to significant vision loss. This review aims to present an up-to-date overview for rheumatologists about the ocular involvement and potential complications of DM and PM and when to refer to the ophthalmologist to avoid sight-threatening complications.

BACKGROUND/AIM: The importance of an accurate determination of central corneal thickness (CCT) relies on its diagnostic and therapeutic implications in glaucoma, corneal ectasias, corneal edema and endothelial function monitoring, and refractive surgery suitability, among others. We aimed to analyze the repeatability, reproducibility, correlation, and laterality variations of CCT measurements performed with the Pentacam HR and the standard of care ultrasound A-scan (USP). METHODS: A cross-sectional study including CCT measurements of healthy individuals was performed by three independent examiners with the Pentacam HR and USP. Intra-observer and inter-observer variations were calculated with intra-class correlation coefficients (ICCs). Bland-Altman plots and 95% limits of agreement (95% LoA) were used to assess the agreement between devices. Linear correlation was calculated with Pearson's coefficient. RESULTS: Thirty individuals (60 eyes), including 10 (33.3%) men and 20 (66.6%) women, with a mean age of 30.0 ± 9.1 years, were studied. No statistical differences were found in CCT measurements between Pentacam HR (range 500â-â609 µm) and USP (range 498â-â628 µm). There was a high degree of correlation in repeatability and reproducibility of each independent device (ICC > 0.90). Pearson's correlation between 1 vs. 2, 2 vs. 3, and 3 vs. 1 Pentacam HR attempts were 0.914, 0.958, and 0.925, respectively (p < 0.001). Corresponding results for USP were 0.957, 0.957, and 0.943 (p < 0.001). The Pentacam HR tended to overestimate CCT by a mean difference of 3.77 µm (95% LoA, - 24.9â-â18.4). Right eyes were also overestimated (- 3.6 ± 14.1 µm) with the Pentacam HR device, whereas left eyes were underestimated (1.3 ± 11.1 µm). CONCLUSIONS: The Pentacam HR device provides reliable operator-independent estimates of CCT. Right eyes exhibited a tendency to overestimate with the Pentacam HR. We suspect this difference is due to USP underestimation related to patients' position while performing the study. In clinically relevant scenarios, performing a third measurement and cautiously measuring right eyes can provide higher accuracy.
RESUMEN
PURPOSE: To describe the demographic characteristics and clinical course of Fuchs endothelial corneal dystrophy (FECD) in a Mexican-mestizo population. METHODS: A retrospective observational and longitudinal study was performed in consecutive patients with the clinical diagnosis of Fuchs endothelial corneal dystrophy seen at our institution. Initial and last follow-up best-corrected visual acuity, slit-lamp findings, and specular microscopy endothelial morphometric parameters were analyzed. RESULTS: One hundred and two eyes belonging to 51 patients were included in the analysis. Median age at the time of diagnosis was 69 years (range, 25-87 years) with a female-to-male ratio of 3.3:1. Visual loss (40%) followed by glare (13.3%) and fluctuating matutine vision loss (13.3%) was the most common complaints at presentation. Regarding FECD staging, 65 (63.7%) were classified as stage-I FECD, 21 (20.6%) stage-II, and 15 (14.7%) as stage-III. A high percentage of eyes (44.1%) presented visual impairment ( ≤ 20/50) at presentation, and the presence of isolated corneal guttata was the most common stage of presentation (64%) at slit-lamp examination. While fifty-nine (57.8%) eyes did not require any medical or surgical management, 17 (16.7%) eyes were managed with hypertonic saline eyedrops alone or in combination with bandage contact lens, and 18 (17.6%) required corneal transplantation. Penetrating keratoplasty alone (8 eyes, 44.4%), or in combination with cataract extraction and intraocular lens implantation (3 eyes, 16.7%), was the most frequent surgical technique performed. CONCLUSION: Demographical characteristics of Fuchs dystrophy regarding age at presentation, gender distribution, and clinical stage at the time of diagnosis did not differ significantly from other international reports. Almost 20% of these patients will require keratoplasty during the disease, emphasizing the need for safer and more reproducible keratoplasty techniques.

PURPOSE: To determine the prevalence, clinical characteristics, and mechanisms of secondary glaucoma in Vogt-Koyanagi-Harada (VKH) disease. METHODS: This retrospective, longitudinal observational study analyzed the demographic data, disease stage, glaucoma development, intraocular pressure, best-corrected visual acuity, lens status, optic nerve, gonioscopy, management, and visual outcomes of VKH disease. Clinical features were used to categorize the stage of VKH disease. VKH eyes were divided into two groups, with or without glaucoma, undergoing further analysis, including statistical analysis. RESULTS: 305 eyes of 155 patients with VKH disease with a median follow-up of 22 months were included. Secondary glaucoma developed in 67 (22%) eyes, most of which (64.2%) had chronic recurrent VKH at presentation. Angle-closure was present in 55 (82.1%) of glaucoma eyes. Peripheral anterior and posterior synechiae were present in 58 (86.6%) and 51 (76.1%) eyes, respectively. Pupillary block and posterior synechiae resulted in iris bombé in 17 (25.4%) eyes with glaucoma. At the last visit, visual acuity was worse in eyes with glaucoma (p < 0.001). CONCLUSION: We found that angle-closure disease is a significant cause of secondary glaucoma in VKH. Eyes with glaucoma were more likely to present in the chronic recurrent stage of the disease.

The objective of this study is to review the ocular surface changes and complications of patients with Sjögren syndrome and assess their visual impact. A retrospective, cross-sectional, observational, and descriptive study of patients with Sjögren syndrome diagnosed according to the American-European Consensus Group criteria was designed. Data including age, gender, the reason for consultation, associated systemic disease, visual acuity, and ocular complications were recorded. Dry eye tests including tear meniscus thickness; tear film break-up time; ocular surface staining (fluorescein and lissamine green); and Schirmer I test were performed. A total of 249 patients, 233 women (93.6%) and 16 men (6.4%) were studied. Meibomian gland dysfunction was found in 46% (n = 229 eyes) patients; shortened tear film break-up time in 44% (n = 220 eyes); decreased tear meniscus in 49% (n = 243 eyes); significant superficial punctate keratopathy in 49% (n = 242 eyes); a mean ocular surface staining score of 5.92 points; and a low score for Schirmer I test (mean = 5.4 mm). Eyes with a 4 + corneal fluorescein score showed the worst BCVA (mean = 0.63 ± 0.66 LogMAR, ≤ 20/80 Snellen eq., 95% CI 0.29-0.97), compared to 1 + to 3 + scores (mean = 0.211 ± 0.37 LogMAR, 20/32 Snellen eq., 95% CI 0.53-1.15). Ten eyes (4.0%) presented central corneal ulceration with a mean visual acuity of 20/500 (96% visual loss). Ocular surface alterations related to severe dry eye and complications from Sjögren syndrome may have a significant impact on visual acuity. Secondary Sjögren syndrome to rheumatoid arthritis had the worse dry eye prognosis, visual outcome, and ocular complications.

PURPOSE: To compare the efficacy and safety of pop-titrated versus fixed-energy diode laser trans-scleral cyclophotocoagulation (DLTSC) for refractory glaucoma. METHODS: This is a prospective, interventional, longitudinal, and comparative case-control study. Patients with refractory glaucoma treated with pop-titrated DLTSC were compared to a fixed-energy DLTSC control group. Variables analyzed included: age, gender, diagnosis, pre- and post-treatment intraocular pressure (IOP). Success rate, anti-glaucoma medications reduction, and complications were analyzed at day 90 post-treatment. Primary success criterion consisted of eyes with a postoperative IOP ≤ 22 mmHg or a 30% reduction of pre-treatment IOP and managed with topical anti-glaucoma medications only. RESULTS: A total of 68 eyes from 67 patients were included for analysis: 30 in the pop-titrated group and 38 in the fixed-energy group. Therapeutic success was achieved in 56-72% of the pop-titrated group versus 47-52% in the fixed-energy group considering the 3 different criteria analyzed (p = 0.23-0.4). There was a 22% (from 4.1 to 3.2 drugs) reduction of anti-glaucoma medications in the pop-titrated group, compared to 32% (from 3.5 to 2.4 drugs) in the fixed-energy group (p = 0.42). Five eyes (13.1%) developed hypotony, all of which belonged to the fixed-energy group (p = 0.048). CONCLUSIONS: Pop-titrated DLTSC represents an effective and safe option for the management of refractory glaucoma. We found no statistically significant difference in success rates among both groups. However, there was a significantly higher risk of hypotony in eyes treated with the fixed-energy protocol.

AIMS: The purpose of this paper was to determine the lacrimal concentration of IL-1α and MMP-9 in patients with active ocular rosacea before and after systemic treatment with azithromycin or doxycycline. METHODS: After 4 weeks of therapy with azithromycin (500 mg/day, 3 days a week PO) or doxycycline (200 mg/day PO), lacrimal samples were analyzed using an enzyme-linked immunosorbent assay multiplex. RESULTS: There was a significant difference between baseline IL-1α (37.9 pg/mL) and MMP-9 (26.7 ng/mL) in rosacea eyes compared to controls (0.001 pg/mL for IL-1α and 0.2 ng/mL for MMP-9) (p < 0.001). IL-1α decreased from 47.0 pg/mL before azithromycin to 23.5 pg/mL after treatment (p = 0.024), but not after doxycycline therapy. On the contrary, baseline MMP-9 tear levels (10.28 ng/mL) decreased after treatment (8.36 pg/mL) with doxycycline (p = 0.054) but not with azithromycin. There was a strong clinical correlation of higher baseline IL-1α tear levels between patients who responded to doxycycline therapy and those who failed (p = 0.043). Patients unresponsive to azithromycin had significantly higher baseline MMP-9 levels than those with doxycycline (p = 0.040). CONCLUSIONS: While IL-1α levels decreased after azithromycin therapy, MMP-9 did so after doxycycline treatment. Baseline cytokine tear levels tend to be markedly elevated in patients with antibiotic failure, suggesting their potential role as therapeutic biomarkers for the disease.

PURPOSE: To report the therapeutic efficacy and safety of topical 0.1% lodoxamide in the long-term treatment of superior limbic keratoconjunctivitis. METHODS: Sixty-seven eyes of 34 patients with active SLK were studied. Therapeutic response was analyzed according to modified-Ohashi parameters. All eyes were treated with 0.1% lodoxamide twice daily, and those with moderate or severe inflammation received a short course (7-14 days) of 0.1% fluorometholone acetate at presentation and during a relapse. Patients were evaluated at regular intervals and followed up for ≥3 months on continuous therapy. Primary endpoints included inflammatory response; rates of inflammatory control and remission; relapses while on therapy or on remission; and therapeutic failure rate. RESULTS: The mean follow-up time on lodoxamide therapy was 15.3 months. The majority of eyes (82.0%) achieved control of inflammation in a mean time of 2.2 months. Of these, 42 (76.3%) eyes remained under control while on therapy for 13.8 months. There was a significant improvement of SLK-related signs by the third month on therapy (p < 0.05). A total of 24 (35.8%) eyes achieved remission. Relapses presented in 12 (18.0%) treated eyes and in 4 (16.6%) eyes on remission. Only 5 (7.4%) eyes failed to respond to therapy. In the majority of cases (95.3%), lodoxamide 0.1% was well tolerated and minor adverse effects not requiring stopping the medication were reported in only 4.7% of patients. CONCLUSIONS: Lodoxamide 0.1% is an efficacious therapeutic alternative for the treatment of active and chronic SLK. This medication has proved to be safe and well tolerated.

To analyze the intraocular pressure reduction, number of anti-glaucoma medications needed, and post-operative complications of trans-scleral diode laser cyclophotocoagulation (DCPC) in patients with high-risk penetrating keratoplasty (PKP) and secondary refractory glaucoma. Prospective interventional, longitudinal, non-comparative series of cases, including 16 eyes of 15 patient's post-PKP on maximal anti-glaucoma medical therapy with intraocular pressures above 22 mmHg. All patients received 18 shots, 360° peri-limbal (avoiding the long posterior ciliary nerves and arteries at 3 and 9 o'clock positions) of trans-scleral DCPC (2000 mW, time: 2.0 s/shot). There was a 55.5 % reduction (total of 14.0 mmHg) of the mean pre-operative IOP (31.5 mmHg) after the first diode laser application (p = 0.0020). Re-treatment was required in 31.2 % of eyes over a mean period of 10.7 months. In these five eyes, the mean pre-operative IOP was 40.4 mmHg, which decreased to 15.0 mmHg post-therapy, and a mean IOP reduction of 25.4 mmHg (p = 0.0218). There was a 51.0 % reduction in the mean number of medications used after the first, and a 57.1 % reduction after a second laser application. The incidence of failure (IOP ≥ 22 mmHg or need of additional medical therapy) from initial intervention to loss of follow-up was 1.3 % per person-month. DCPC effectively reduces the intraocular pressure and the number of anti-glaucoma medications with few complications in patients after high-risk PKP and secondary glaucoma. Only, one-third of the eyes needed a second intervention to control the intraocular pressure. Post-DCPC complications were limited to phthisis bulbi and endothelial dysfunction, one eye each. Please check and confirm the author names and initials are correct. Also, kindly confirm the details in the metadata are correct.

Necrotizing scleritis is an immune-mediated ocular inflammatory process, characterized by an area of avascular necrosis and a profound inflammation of the sclera and episclera. Necrotizing scleritis and its association with peripheral ulcerative keratitis--necrotizing sclerokeratitis (NS)--represents a serious threat for vision and eye integrity, evolves very fast if untreated, and its finding suggests the presence of a potentially lethal systemic vasculitic process.

BACKGROUND: To analyze the clinical course and outcomes of autoimmune vs. non-autoimmune surgically induced scleral necrosis (SISN). METHODS: Multicentric, retrospective, comparative cohort study. Eighty-two eyes of 70 patients with SISN were classified according to pathogenic mechanism into autoimmune vs. non-autoimmune. Main outcome measures included necrosis onset, type of surgery, associated systemic disease, visual acuity, and treatment were analysed in patients followed for ≥ 6 months. RESULTS: Forty-six (65.7%) patients were women, and the median age was 66 (range: 24-90) years. Most patients (82.9%) had unilateral disease. The median time between surgery and SISN onset was 58 (1-480) months. Thirty-one (37.8%) eyes were classified as autoimmune, and 51 (62.2%) as non-autoimmune SISN. Autoimmune SISN was associated with a shorter time between the surgical procedure and SISN onset than non-autoimmune cases (median of 26 vs. 60 months, p = 0.024). Also, autoimmune SISN was associated with cataract extraction (93.5% vs. 25.5%, p < 0.001), severe scleral inflammation (58.1% vs. 17.6%, p < 0.001), and higher incidence of ocular complications (67.7% vs. 33.3%, p = 0.002) than non-autoimmune cases. Remission was achieved with medical management alone in 44 (86.3%) eyes from the non-autoimmune and in 27 (87.1%) from the autoimmune group (p = 0.916). Surgical management was required in 11 (13.4%) eyes, including two requiring enucleations due to scleral perforation and phthisis bulbi. CONCLUSIONS: Eyes with autoimmune SISN had a higher rate of cataract surgery, severe scleral inflammation, and ocular complications. Early SISN diagnosis and appropriate management, based on clinical features and pathogenic mechanisms, are critical to avoid sight-threatening complications.
RESUMEN
Importance: Pediatric blepharokeratoconjunctivitis (PBKC) is a chronic, sight-threatening inflammatory ocular surface disease. Due to the lack of unified terminology and diagnostic criteria, nonspecific symptoms and signs, and the challenge of differentiation from similar ocular surface disorders, PBKC may be frequently unrecognized or diagnosed late. Objective: To establish a consensus on the nomenclature, definition, and diagnostic criteria of PBKC. Design, Setting, and Participants: This quality improvement study used expert panel and agreement applying the non-RAND modified Delphi method and open discussions to identify unified nomenclature, definition, and definitive diagnostic criteria for PBKC. The study was conducted between September 1, 2021, and August 14, 2022. Consensus activities were carried out through electronic surveys via email and online virtual meetings. Results: Of 16 expert international panelists (pediatric ophthalmologists or cornea and external diseases specialists) chosen by specific inclusion criteria, including their contribution to scientific leadership and research in PBKC, 14 (87.5%) participated in the consensus. The name proposed was "pediatric blepharokeratoconjunctivitis," and the agreed-on definition was "Pediatric blepharokeratoconjunctivitis is a frequently underdiagnosed, sight-threatening, chronic, and recurrent inflammatory eyelid margin disease associated with ocular surface involvement affecting children and adolescents. Its clinical spectrum includes chronic blepharitis, meibomitis, conjunctivitis, and corneal involvement ranging from superficial punctate keratitis to corneal infiltrates with vascularization and scarring." The diagnostic criteria included 1 or more suggestive symptoms accompanied by clinical signs from 3 anatomical regions: the eyelid margin, conjunctiva, and cornea. For PBKC suspect, the same criteria were included except for corneal involvement. Conclusions and Relevance: The agreements on the name, definition, and proposed diagnostic criteria of PBKC may help ophthalmologists avoid diagnostic confusion and recognize the disease early to establish adequate therapy and avoid sight-threatening complications. The diagnostic criteria rely on published evidence, analysis of simulated clinical cases, and the expert panel's clinical experience, requiring further validation with real patient data analysis.

INTRODUCTION: VKH is a primary stromal choroiditis. Studies with indocyanine green angiography (ICGA) have shown that inflammation begins at the choroid and may persist without clinically apparent inflammation. Thus, systemic therapy must target choroidal inflammation and be maintained until the choroiditis resolves, as proven by ICG and/or EDI-OCT imaging studies. DISCUSSION: Aggressive therapy with oral corticosteroids, with or without "pulsed" intravenous methylprednisolone, has been the mainstay of VKH therapy in the acute phase for many years. However, there is convincing evidence that corticosteroid monotherapy is insufficient to prevent progression onto the chronic recurrent form of the disease, which is associated with poor visual outcomes. CONCLUSION: Numerous studies suggest that combined therapy with systemic corticosteroids and immunosuppressants is necessary to prevent the progression toward chronic recurrent disease, avoiding complications, get a better control of inflammation and visual outcomes in VKH patients seen at the uveitic phase of the disease.

Objective: Surgically induced scleral necrosis (SISN) is a potentially blinding sequela that may occur after any ocular procedure. SISN in the context of active tuberculosis is seldom seen. We report a case of a patient with asymptomatic tuberculosis who developed SISN after pterygium surgery. Methods: A 76-year-old Mexican-mestizo woman from Veracruz, Mexico, was referred to our clinic because of severe disabling pain and scleral thinning in her right eye. Results: Tubercular-related SISN was finally diagnosed and managed successfully with antitubercular therapy, topical and systemic corticosteroids. Conclusion: Tuberculosis must be considered as a differential diagnosis of high-risk patients in the context of refractory SISN in endemic countries.
RESUMEN
BACKGROUND/AIMS: To evaluate the role of early immunosuppressive therapy (IMT) in the management of rheumatoid arthritis (RA)-associated peripheral ulcerative keratitis (PUK). METHODS: Single-centre, retrospective, comparative cohort study. Patients with RA-associated PUK were divided into two groups; those exposed to and those not exposed to early IMT, defined as administrating therapy within the first 4 weeks from the PUK onset. Outcomes included PUK recurrence, control of inflammation and development of ocular complications, including corneal scarring and perforation, cataract formation or progression and permanent visual loss. RESULTS: A total of 52 eyes from 36 patients were included for analysis; 37 (71.2%) eyes received early IMT and 15 (28.8%) eyes did not. Follow-up time was 41.2+53.3 months (range: 4-236 months). While early IMT was a protective factor (HR 0.345, 95% CI 0.126 to 0.946, p=0.039), late RA diagnosis after PUK onset (HR 4.93, 95% CI 1.75 to 13.85, p=0.002) and retarded (≥2 months) control of inflammation (HR 8.37, 95% CI 1.88 to 37.16, p=0.005) were risk factors for PUK recurrence. Late IMT (OR 7.75, 95% CI 2.00 to 29.99, p=0.003), an unknown diagnosis of RA at first visit (OR 4.14, 95% CI 1.15 to 14.91, p=0.030) and at least one PUK recurrence (OR 6.42, 95% CI 1.71 to 24.07, p=0.006) were risk factors for visual loss. Survival analysis rendered eyes exposed to early IMT a lower risk of PUK recurrence (p=0.039). CONCLUSION: Eyes with RA-associated PUK exposed to early IMT were more likely to achieve earlier inflammatory control, fewer recurrences and had better visual outcomes.
