RESUMO
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).

Blepharitis is a very common disease in ophthalmology, dermatology and allergy practice. It generally follows a chronic course and is frequently associated with objective and/or subjective symptoms such as epiphora, red eye, dandruff, gritty sensation, itching, burning, photophobia, and blurred vision. The purpose of this study is to analyze the prevalence of Demodex spp. in patients with symptoms of chronic blepharitis. An analytical cross-sectional study was conducted in the period between 2016 and 2020. All patients with symptoms of chronic blepharitis who underwent a parasitological test of eyelashes (Rapitest) in the Dermatology Department of the Hospital Italiano de Buenos Aires were included. Those with previously established blepharitis due to another infectious cause were excluded. We analyzed 972 patients. Sixty percent (n=585) underwent a positive Rapitest for the presence of Demodex spp. Seventy five percent (n=728) were women. There were no significant differences in the prevalence associated with sex (p=0.38). Among the patients positive for Demodex spp., 65% (n=628) were older than 60 years old. The most frequently associated symptom was itching, present in 35% (n=342). A statistically significant decrease in the number of consultations was observed during the cold months of the year (May-June-July-August). Our results show a high prevalence of Demodex spp. in patients with chronic blepharitis. As its presence reveals a direct association with age, we recommend looking for this parasite in this age group.

BACKGROUND: To evaluate the efficacy of topical ivermectin 1% ointment, for the treatment of Demodex blepharitis. METHODS: A retrospective study was designed to review electronic medical records of patients seen between January 2017 and December 2022, who had a diagnosis of Demodex blepharitis, treated with topical ivermectin 1% with at least 6 months of follow-up (Centro de Ojos Quilmes, Buenos Aires, Argentina). The presence of collarettes was graded from 0 to 4. An imaging system (Keratograph) was used, to evaluate tear meniscus height (TMH), non-invasive tear break-up time (NIKBUT), and degree of conjunctival redness. In addition, the ocular surface disease index (OSDI) test was performed. Results were compared before and after ivermectin treatment, which was performed once a day for 2 months. RESULTS: A total of 2157 patients (4314 eyes) were included. The mean age was 50.43 ± 15.3 years, and the follow-up time was 26.1 ± 8.5 months. No one discontinued treatment due to intolerance, although 14 cases (0.6 %) reported occasional discomfort. The grade of collarettes decreased with statistical significance, from 3.37 ± 0.7 to 0.1 ± 0.3 (p < 0.01), as well as conjunctival redness from 1.32 ± 0.3 to 0.94 ± 0.4 (p < 0.01) and OSDI score from 58.74 ± 17.9 to 17.1 ± 10.5 (p = 0.02). TMH and NIKBUT improved without statistical difference. CONCLUSION: Treatment with ivermectin 1% topical ointment, once daily for 2 months, was effective in reducing the presence of collarettes and in improving symptoms in patients with Demodex blepharitis.

OBJECTIVES: To describe the most common ocular lesions and demonstrate the frequency of ophthalmic involvement in a group of cats with systemic sporotrichosis. ANIMALS STUDIED: Two hundred seventy-four cats diagnosed with systemic sporotrichosis. The inclusion criteria included previous positive cytopathological examination, histopathological examination, or fungal culture. PROCEDURES: In a prospective case-control study, 274 cats diagnosed with systemic sporotrichosis underwent ophthalmic evaluation and received treatment for systemic sporotrichosis. Of these animals, 63 had ocular abnormalities which were recorded, and conjunctivitis was scored from 0 to 5. Diagnostic techniques utilized included fungal culture, as well as cytopathological (10 eyes; 10 cats), and histopathological examination of the palpebral conjunctiva and eyes (2 eyes). RESULTS: Cytopathological and histopathological examination of the conjunctiva, as well as fungal culture, proved to be important tests for the detection of Sporothrix sp. Five cats without the evidence of ophthalmic abnormalities also had a positive fungal culture. The identified ocular lesions in animals with systemic sporotrichosis included increased serous discharge (79 eyes; 53 cats), blepharoconjunctivitis (33 eyes; 25 cats), conjunctivitis (39 eyes, 20 cats), blepharitis (9 eyes; 8 cats), uveitis (5 eyes; 3 cats), and Florida keratopathy-like lesions (2 eyes; 1 cat). CONCLUSION: Sporotrichosis should be considered a differential diagnosis for conjunctivitis and blepharoconjunctivitis, especially in endemic areas. Fungal culture and cytopathology of ocular discharge and histopathological examinations of the conjunctiva are important for the diagnosis of ophthalmic sporotrichosis, although not all cats underwent laboratory testing in this study. Ocular discharge could be a source of contagion transmission.

ABSTRACT Purpose: Ocular disorders are among the most frequent manifestations of psoriatic arthritis. The incidence, type, and severity of these disorders may be influenced by genetics, local environmental factors, and access to ophthalmic treatment. Here we describe the ocular manifestations of psoriatic arthritis among denizens of the Amazon region of Para, Brazil, treated by the rheumatology service of Universidade do Estado do Pará. Methods: This cross-sectional study examined 23 psoriatic arthritis patients (median age 47.78 years, no sex predominance) diagnosed according to Caspar's criteria. Disease activity was evaluated according to the Clinical Disease Activity Index for Psoriatic Arthritis. Ophthalmological examinations performed included visual acuity with distance correction, biomicroscopy, applanation tonometry, fundoscopy, Schirmer test I, tear breakup time, fluorescein staining, and lissamine green staining. Patients also completed The Ocular Surface Disease Index questionnaire. Results: The most common ophthalmic disorders were dry eye (60.9%), cataracts (56.5%), blepharitis (47.8%), keratitis (43.5%), meibomitis (30.4%), pterygium (26, 1%), and pinguecula (13%). More than half of all patients demonstrated recent onset (>5 years), the peripheral disease type, and severe symptoms according to Clinical Disease Activity Index for Psoriatic Arthritis. Conclusion: The ocular manifestations of psoriatic arthritis are varied and mainly affect the ocular surface. Regular ophthalmological follow-up is recommended for patients in the early stage with high disease activity.
RESUMO Objetivo: Descrever as manifestações oftalmológicas observadas em pacientes com artrite psoriásica atendidos no Serviço de Reumatologia da Universidade do Estado do Pará. Métodos: Estudo transversal. A amostra foi composta por 23 pacientes com artrite psoriásica, segundo os critérios de Caspar, atendidos no ambulatório de reumatologia da Universidade do Estado do Pará. Para avaliação da atividade de doença foi aplicado o Clinical Disease Activity index for Psoriatic Arthritis e, posteriormente, foi realizado o exame oftalmológico (acuidade visual com correção para distância, biomicroscopia, tonometria de aplanação de Goldmann, fundoscopia, teste de Schirmer I, tempo de ruptura do filme lacrimal, lissamina verde e questionário The Ocular Surface Disease Index). Resultados: Nesta pesquisa não houve predomínio entre os sexos e a população tinha uma mediana de idade de 47,78 anos. As manifestações mais comuns foram olho seco (60,9%), catarata (56,5%), blefarite (47,8%), ceratite (43,5%), meibomite (30,4%) e pterígio (26,1%). Conclusão: As manifestações oculares encontradas em pacientes com artrite psoriásica são variadas e afetam sobretudo a superfície ocular; no entanto, são clinicamente subestimadas; por isso recomenda-se o acompanhamento oftalmológico regular e periódico para pacientes com artrite psoriásica.
RESUMO
ABSTRACT The objective of this report is to describe a case of meibomian gland dysfunction associated with keratoconus and to examine the importance of treatment for evaporative dry eye in cases of corneal ectasia. A 45-year-old man diagnosed as having keratoconus complained of burning, tearing, itching, and red eye. He had a history of penetrating corneal transplantation and wearing rigid contact lenses. The meibography revealed a severe meibomian gland dropout and normal tear meniscus height in both eyes. Objective propaedeutic tests are important tools for dry eye diagnosis and proper evaluation of ocular surface and tear film. In older patients, the classic signs of atopic conjunctivitis are not always present, and the causes of chronic rubbing must be further investigated. Treatment of underlying chronic inflammation such as dry eye, meibomian gland dysfunction, and blepharitis might be important to prevent keratoconus progression and guarantee symptom relief.
RESUMO O objetivo é relatar um caso de associação entre disfunção de glândulas de meibomius (DGM) e ceratocone, assim como ressaltar a importância do tratamento do olho seco evaporativo em casos de ectasia corneana. Paciente do sexo masculino de 45 anos com ceratocone e queixas de ardência, lacrimejamento, prurido e olho vermelho. O mesmo tem histórico de transplante de córnea penetrante e uso de lentes de contato rígidas. A meibografia revelou severa perda de glândulas de meibomius e menisco lacrimal normal em ambos os olhos. Testes propedêuticos objetivos são importantes ferramentas para diagnóstico de olho seco e apropriada avaliação da superfície ocular e filme lacrimal. Em pacientes mais velhos, os sinais clássicos de atopia não estão sempre presentes e investigações adicionais das causas de prurido crônico são necessárias. O tratamento da inflamação crônica subjacente como olho seco, disfunção de glândulas de meibomius e blefarite podem ser importantes para prevenir a progressão do ceratocone e garantir alívio dos sintomas.
RESUMO
PURPOSE: To evaluate the safety and efficacy of lotilaner ophthalmic solution, 0.25% for the treatment of blepharitis due to Demodex infestation compared to vehicle control. METHODS: In this phase II, randomized, controlled, double-masked clinical trial, 60 eligible participants with Demodex blepharitis were randomly assigned in a 1:1 ratio to receive either topical lotilaner ophthalmic solution, 0.25% (Tarsus Pharmaceuticals, Inc., Irvine, CA) (study group) or the vehicle without lotilaner (control group) bilaterally twice a day for 28 days. Participants were followed at Days 7, 14, 28, 60 and 90. The efficacy parameters were change in collarette grade and Demodex density at Day 28. Safety parameters were adverse events, changes in corrected distance visual acuity (CDVA), intraocular pressure (IOP) and slit-lamp biomicroscopy. RESULTS: The study group showed a statistically significant decrease in collarette grade compared to the control group beginning at Day 14 (p = 0.003) in the upper eyelid and at Day 28 (p = 0.003) in the lower eyelid. Decreases in both lids were maintained through Day 90 (p < 0.001). At Day 28, mite eradication was achieved in 66.7% and 25.9% of eyes in the study and control group (p = 0.005); at Day 90, these proportions were 68.2% and 18.5% (p = 0.001), respectively. No serious adverse events or clinically significant changes in CDVA and IOP were observed. CONCLUSION: For Demodex blepharitis, treatment with lotilaner ophthalmic solution, 0.25% for 4 weeks is safe and effective. The improvement in collarette grade and mite density observed during the treatment period persisted for at least two months following treatment cessation.

Purpose: To evaluate the efficacy of topical lotilaner ophthalmic solution, 0.25%, in patients with Demodex blepharitis. Methods: Eighteen adults with Demodex blepharitis, defined as >10 collarettes on the upper lid and/or mite density of ≥1.5 mites per lash (upper and lower), were treated bid for 42 days with the topical lotilaner ophthalmic solution, 0.25%. Contact lens wear, artificial eyelashes, and lid structural abnormalities were among the exclusion criteria. No other antibacterial, antiparasitic, or anti-inflammatory treatment or lid hygiene products were permitted. One eye of each patient was selected for analysis and assessed on day 7, 14, 28, and 42. Collarettes were graded at each visit, and mite density was evaluated by microscopy at each visit except day 7. Outcome measures were collarette elimination (≤2 lashes with collarettes) and mite eradication (0 mites). Drop tolerability, adverse events, visual acuity, and slit-lamp biomicroscopy were assessed. Results: Collarette elimination was achieved in 13/18 participants (72.2%) by day 42. Mean collarette grade (upper lid) declined from 3.56 ± 0.17 to 0.28 ± 0.11. Mite eradication was achieved in 14/18 participants (77.8%) by day 42. Mean mite density decreased from 2.63 ± 0.39 to 0.12 ± 0.08 mites/lash. Participants reported good tolerability. Adverse events were mild and transient and did not result in treatment discontinuation. Conclusion: Six weeks of at-home topical therapy with the lotilaner ophthalmic solution, 0.25%, was effective in eliminating the most common objective signs of Demodex blepharitis, with a collarette elimination rate of 72% and mite eradication in 78% of eyes by day 42.

Due to the prevalence of acne vulgaris, isotretinoin is one of the most prescribed drugs among physicians and dermatologists. Although exhibiting an adequate safety profile, adverse events secondary to isotretinoin use are common. Before prescribing isotretinoin, physicians usually inquire about pregnancy and perform serologic tests including cholesterol, triglycerides, and liver enzymes. Ocular manifestations are commonly neglected. Despite being generally mild, ocular manifestations related to either topical or systemic isotretinoin may cause important ocular morbidity. The ocular surface is the most affected site within the eye; however, retinal and optic nerve disease also have been documented. Evaporative dry eye disease, which may range from mild to severe, is the most common adverse ocular effect associated with isotretinoin use. The aim of this review is to present an up-to-date overview for the dermatologist about the prevention, diagnosis, and treatment of the ocular side effects of isotretinoin, and when to refer to the eye specialist.

RESUMEN Fundamento: la blefaritis es una enfermedad común en la práctica oftalmológica, de curso crónico con crisis de exacerbación y causa multifactorial, a menudo se le asocia a Demodex spp., ácaro del folículo piloso, parásito extendido y frecuente; su infestación en humano se conoce como demodecosis. Objetivo: caracterizar desde el punto de vista clínico a pacientes con blefaritis y demodecosis. Métodos: se realizó un estudio descriptivo, transversal, en el Hospital Militar Clínico Quirúrgico Docente Dr. Octavio de la Concepción y de la Pedraja de la provincia Camagüey desde septiembre de 2017 a noviembre de 2018. La población objeto de estudio quedó conformada por 84 pacientes con diagnóstico de blefaritis en quienes se confirmó presencia de Demodex spp. que cumplieron criterios definidos por el autor. Se estudiaron variables biológicas (edad y sexo), clínica (síntomas y signos). Los resultados se expusieron en tablas, se utilizó estadística descriptiva para distribuciones de frecuencias. Se respetaron aspectos éticos para investigación en humanos. Resultados: en más de la mitad de los pacientes con diagnóstico de blefaritis se confirmó la presencia de Demodex spp., predominó los enfermos mayores de 61 años, así como del sexo femenino, las manifestaciones clínicas con mayor incidencia fueron: presencia de caspa cilíndrica, alteraciones de las pestaña, escozor y prurito, seguidos por inestabilidad de la película lagrimal, alteraciones de bordes palpebrales, queratitis superficial y sensación de cuerpo extraño. Conclusiones: el estudio demostró la presencia del Demodex spp. en un importante número pacientes con blefaritis lo que contrasta que, en Cuba no existe suficiente literatura documentada que muestre su prevalencia, comportamiento o técnicas diagnósticas, así como variantes terapéuticas eficientes en esta enfermedad.
ABSTRACT Background: the blepharitis is a common illness in the ophthalmological practice, of chronic course with exacerbation crisis and multifactorial etiology, often associated with Demodex spp., mite of the hair follicle, extended and frequent parasite; its infestation in human is known as demodecosis. Objective: to characterize from the clinical point of view patients with blepharitis and demodecosis. Methods: a descriptive, traverse study was carried out in the Educational Surgical Clinical Military Hospital Dr. Octavio of the Concepción and of the Pedraja of Camagüey in the period of September, 2017 to November, 2018. The population study object was conformed by 84 patients with diagnostic of blepharitis who were confirmed with the presence of Demodex spp. and they completed criteria defined by the author. Biological variables were studied (age and sex) and clinic (symptoms and signs). The results were exposed in charts using descriptive statistic for distributions of frequencies. Ethical aspects for investigation in human were respected. Results: in more than half of the patients with diagnostic of blepharitis was confirmed the presence of Demodex spp., the sick persons older than 61 years prevailed, as well as of the feminine sex, the clinical manifestations with more incidence were: presence of cylindrical dandruff, alterations of the lash, smarting and pruritus, continued by uncertainty of the lachrymal movie, alterations palpebral embroider, superficial keratitis and sensation of strange corpse in the eye. Conclusions: the study demonstrates the presence of the Demodex spp. in an important number patient with blepharitis which contrasts with, in Cuba there isn´t enough documented literature that shows their prevalence, behavior or diagnostic techniques, as well as efficient therapeutic variants in this illness.
