Lagoftalmo na hanseníase: experiência clínica em centro de referência amazonense / Lagophthalmos in leprosy: clinical experience in an Amazon reference center

RESUMO Objetivo: O presente trabalho teve por objetivo caracterizar o perfil epidemiológico e clínico de pacientes com lagoftalmo associado à hanseníase, atendidos no ambulatório de oftalmologia da Fundação Alfredo da Matta, Manaus, Amazonas. Métodos: Trata-se de estudo retrospectivo realizado por meio da análise dos prontuários clínicos dos pacientes incluídos no estudo. Sexo, idade, forma clínica, grau de incapacidade no diagnóstico e desfecho foram obtidos dos prontuários. Início, tipo de comprometimento (unilateral ou bilateral), grau de intensidade do lagoftalmo e alterações oculares associadas também foram compilados. Resultados: Foram incluídos 65 pacientes; 66,1% eram do sexo masculino e 53,8% tinham idade superior a 60 anos. Em relação à classificação operacional da hanseníase, a maioria dos pacientes (81,5%) era multibacilar: 33,8% na forma de hanseníase borderline e 47% virchowiana. 36,9% casos apresentavam sequelas oculares associadas ao lagoftalmo: opacidade corneana, epífora, ceratopatia em faixa, e neovascularização corneana.41,6% evoluíram para a cegueira. O lagoftalmo foi conduzido de forma clínica em 23 pacientes e a abordagem cirúrgica foi indicada em 42. Em relação ao tratamento cirúrgico consistiu principalmente no implante de peso de ouro e na cantoplastia de Tessier. Discussão: O lagoftalmo nessa casuística acometeu mais homens idosos, esteve relacionado à forma multibacilar, com hanseníase do tipo virchowiano como relatado na literatura. O diagnóstico de lagoftalmo foi tardio na maioria dos casos, explicando o grande número de sequelas incluindo a cegueira. Conclusão: O presente estudo reforça a necessidade de acompanhamento oftalmológico precoce para que as potenciais e graves sequelas associadas a essa condição sejam evitadas.

ABSTRACT Objective: The present study aimed to characterize the epidemiological and clinical profile of patients with lagophthalmos associated with leprosy, seen at the ophthalmology outpatient clinic of Fundação Alfredo da Matta, Manaus, Amazonas. Methods: This is a retrospective study carried out by analyzing the medical records of the patients included in the study. Sex, age, clinical form, degree of disability in diagnosis and outcome were obtained from medical records. Onset, type of impairment (unilateral or bilateral), degree of intensity of lagophthalmos and associated eye changes were also compiled. Results: 65 patients were included; 66.1% were male and 53.8% were older than 60 years. Regarding the operational classification of leprosy, most patients (81.5%) were multibacillary: 33.8% in the form of borderline leprosy and 47% virchowian. 36.9% of cases had ocular sequelae associated with lagophthalmos: corneal opacity, epiphora, band keratopathy, and corneal neovascularization.41.6% progressed to blindness. Lagophthalmos was performed clinically in 23 patients and the surgical approach was indicated in 42. Regarding surgical treatment, it consisted mainly of gold weight implantation and Tessier's canthoplasty. Discussion: Lagophthalmos in this sample affected more elderly men, was related to the multibacillary form, with leprosy-like leprosy as reported in the literature. The diagnosis of lagophthalmos was delayed in most cases, explaining the large number of sequelae including blindness. Conclusion: The present study reinforces the need for early eye care so that the potential and serious sequelae associated with this condition are avoided.

COVID-19 and the Unfinished Agenda of VISION 2020.

PURPOSE: To critically evaluate the potential impact of the coronavirus disease (COVID-19) pandemic on global ophthalmology and VISION 2020. DESIGN: Perspective supplemented with epidemiologic insights from available online databases. METHODS: We extracted data from the Global Vision Database (2017) and Global Burden of Disease Study (2017) to highlight temporal trends in global blindness since 1990, and provide a narrative overview of how COVID-19 may derail progress toward the goals of VISION 2020. RESULTS: Over 2 decades of VISION 2020 advocacy and program implementation have culminated in a universal reduction of combined age-standardized prevalence of moderate-to-severe vision impairment (MSVI) across all world regions since 1990. Between 1990 and 2017, low-income countries observed large reductions in the age-standardized prevalence per 100,000 persons of vitamin A deficiency (25,155 to 19,187), undercorrected refractive disorders (2,286 to 2,040), cataract (1,846 to 1,690), onchocerciasis (5,577 to 2,871), trachoma (506 to 159), and leprosy (36 to 26). Despite these reductions, crude projections suggest that more than 700 million persons will experience MSVI or blindness by 2050, principally owing to our growing and ageing global population. CONCLUSIONS: Despite the many resounding successes of VISION 2020, the burden of global blindness and vision impairment is set to reach historic levels in the coming years. The impact of COVID-19, while yet to be fully determined, now threatens the hard-fought gains of global ophthalmology. The postpandemic years will require renewed effort and focus on vision advocacy and expanding eye care services worldwide.

Prevalence of ocular findings in a sample of Egyptian patients with psoriasis.

BACKGROUND: Psoriasis is a common disorder worldwide. The prevalence of psoriasis in Egypt, an African country with a Caucasian population, ranges 0.19-3%. Despite this relatively high prevalence of psoriasis, there are no epidemiologic data regarding the burden of associated eye affection. Determining the magnitude of the problem could help in offering better integrated health services. AIM: The purpose of this study was to evaluate eye involvement in a sample of Egyptian psoriatic patients. PATIENTS AND METHODS: This case-control study included 100 patients with psoriasis and 100 age and sex matched healthy controls. Psoriasis extent and severity was graded by psoriasis area and severity index (PASI). Complete ophthalmological examination and tests for dry eye were performed to all subjects. RESULTS: The mean age of the psoriasis group was 50.7 ± 14.3 years. Thirty eight percent of the cases were females. The mean duration of psoriasis was 10.1 ± 7.5 years. Psoriasis patients had more conjunctival injection (n = 40, P = 0.035), more pinguecula (n = 38, P = 0.048) than controls. Ocular surface disease index (OSDI), tear breakup time (TBUT), Schirmer I, and Rose Bengal staining showed statistically significant positive results in the psoriasis group. CONCLUSION: This is the first report on the prevalence of eye comorbidities in Egyptian psoriatic patients. Dry eyes were more common with psoriasis, particularly the erythrodermic type. Other ocular findings were not statistically significantly different except for conjunctival injection and pinguecula.

Ocular leprosy.

Ocular involvement in leprosy is estimated to be 70-75%, about 10-50% of leprosy patients suffer from severe ocular symptoms, and blindness occurs in about 5% of patients. The disease leads to many ophthalmologic symptoms and signs in the range of the eyeball itself, as well as of the bulb adnexa, ie, eyebrows, eyelids with eyelashes, and lacrimal drainage system. Especially dangerous are complications of lagophthalmos and corneal hypoanesthesia, neurotrophic or infectious keratitis, and iridocyclitis and cataract formation, which may lead to significant decrease of visual acuity or even blindness. Multidrug treatment rapidly interrupts transmission of Mycobacterium leprae by infectious patients, but even after being completed, it does not guarantee the withholding of ocular complications.

Longitudinal ocular survey of 202 Filipino patients with multi-bacillary (MB) leprosy treated with 2 year WHO-multiple drug therapy.

The aim of this study was to describe the ocular conditions in multibacillary (MB) leprosy patients treated with 2 year WHO multiple drug therapy (MDT), consisting of dapsone, clofazimine and rifampin, a regimen expected to reduce ocular complications of leprosy. We conducted comprehensive eye examinations in 202 Filipino MB leprosy patients before, during, and after WHO 2 year MDT. Assessments were carried out for at least 5 years. Inflammatory "lepra" reactions occurred in 62% (reversal reaction, 52%; erythema nodosum leprosum, 10%); most were mild. Eye abnormalities consisted mostly of diminished corneal sensitivity before MDT (6%) and lagopthalmos (n = 7, 3.4%). Six of 7 lagopthalmos cases occurred in a subset of 132 patients with facial patches (5%). Visual acuity scores, intra-ocular pressures and pupil cycle times were unremarkable. Bacillary invasion, keratitis, episcleritis, iridocyclitis, ectropion, synechiae, glaucoma and cataract formation were not detected. Scleral clofazimine pigmentation was frequent, resolving in most within 3 years of treatment cessation. Facial patches at presentation may denote a higher risk for lagopthalmos. We propose the generally low rates of ocular problems reflected mild lepra reactions, due to anti-inflammatory properties of clofazimine, a relatively young cohort, and a readily accessible community-based clinic permitting earlier diagnosis and prompt treatment.

The prevalence of ocular complications in leprosy patients seen in the United Kingdom over a period of 21 years.

OBJECTIVE: The objective of this study was to determine the prevalence of ocular complications and blindness among leprosy patients presenting in the United Kingdom. METHODS: Observational prospective study. RESULTS: A total of 126 consecutive leprosy patients attending their ophthalmic visit were examined, out of which 18 patients were blind in one eye (14.3%) and five patients were blind in both the eyes (4.0%). Visual acuity of ≥ 6/18 was present in 96 patients (76.2%). A total of 65 patients (51.6%) had an ocular complication and 28 patients (22.2%) had a sight-threatening leprosy complication (lagophthalmos, severe corneal, or iris disease). The most common ocular complications were impaired lid closure (24 patients, 19%), impaired corneal sensation (20 patients, 15.9%), cataract (20 patients, 15.9%), mild corneal opacity (17 patients, 13.5%), and iris atrophy (17 patients, 13.5%). Impaired corneal sensation was associated with vision <6/18 (P<0.001, OR 13.5, 95% CI 5.14-35.44) and vision <3/60 (P=0.01 OR 6.42, 95% CI 2.15-19.15). Impaired lid closure was significantly associated with increasing age (P=0.029, OR 1.039, 95% CI 1.0-1.08) and vision <3/60 (P=0.03, OR 6.06, 95% CI 1.81-20.24). CONCLUSION: There is a significant rate of ocular complications and blindness seen in leprosy patients in the United Kingdom, and over one in five had a potentially sight-threatening ocular complication. Health professionals and all leprosy patients, including those cured of the disease, need to be aware that new eye symptoms and signs require prompt ophthalmology review to prevent avoidable blindness, due to the life-long risk of sight-threatening ocular complications.

Visual impairment in patients with leprosy in Adilabad District in the state of Andhra Pradesh, India.

The aim was to estimate the prevalence of eye problems in patients with leprosy and to assess the utilization rate of eye care services using cross-sectional case series design. All leprosy patients registered between April 2007 and June 2009 were included in the study. They were prospectively assessed by an internist for general health issues. An ophthalmic examination including assessment of visual acuity was conducted by an ophthalmologist. A total of 150 leprosy patients were examined, of which 78 (52%) suffered from pausi bacillary (PB) leprosy and majority were males (52%); 43 (29%) patients were literate. Nineteen (14%) patients had organ deformities and ocular lesions were seen in 12 (8%) patients, but 76 (51%) (95% CI 40.8-62.7) patients had earlier reported eye problems requiring intervention as assessed by the ophthalmic officer. Only 26 (17%) (95% CI 11.6-24.4) patients had sought eye care services earlier. Visual impairment was observed in 19 (12.6%) cases and blindness related to leprosy was seen in 5 (3.3%) patients. To conclude prevention of blindness among leprosy patients is possible only with strong coordination between the general health and eye care unit in the area with mandatory eye screening being made part of the treatment schedule for leprosy patients.

Ocular abnormalities in atopic dermatitis in Indian patients.

BACKGROUND AND AIMS: Atopic dermatitis (AD) is a common skin disease. Long-standing, severe AD with repeated scratching and rubbing of the face, which requires continuous dermatologic care, predisposes the patient to various ocular complications. The knowledge of the frequency and significance of these ocular complications may allow their early diagnosis and treatment. The present study assesses the ocular complications in Indian children suffering from AD. METHODS: In order to study the ocular complications in AD, 100 patients (61 male and 39 female) between the ages of 1 and 14 years were recruited. All the patients had complete dilated fundus examination with indirect ophthalmoscopy. The lid, conjunctiva and cornea were examined. Also, any evidence of cataract formation and retinal disorders were recorded. RESULTS: The mean age of the children was 5.4 years. Forty-three (43.0%) AD patients showed ocular abnormalities in the form of lid and conjunctival changes. Of these, 18 (41.9%) patients showed only lid involvement, 16 (37.2%) only conjunctival involvement and both conjunctival and lid changes were seen in nine (20.9%) patients. Conjunctival changes were mostly in the form of a cobblestone appearance of the papillae, with mild to moderate papillary reaction and papillary hypertrophy. Variables observed to have a significant impact on the development of ocular abnormalities were age more than 5 years, duration of illness >12 months, positive family history of atopy, presence of palmar hyperlinearity and a combination of both xerosis and Dennie-Morgan fold. CONCLUSIONS: The present study is the first of its kind from India to document an association between AD in children and various ocular manifestations. The ocular manifestations observed in our cohort were not associated with significant ocular morbidity or visual impairment possibly because of a less-severe disease in Indians.

Pattern and determinants of ocular complications in leprosy patients in eastern Nepal.

BACKGROUND: odular complications of leprosy can lead to blindness. OBJECTIVE: to report the pattern and determinants of ocular complications in patients with leprosy from eastern Nepal. METHODS: a cross-sectional study was carried out analyzing one hundred and eighty six patients of leprosy presenting between Jan 2002-Nov 2004. All the patients were categorized using WHO and Ridley and Jopling classification. After determining bacillary indices in all of them, a detailed ocular examination was carried out. Independent risk factors were determined for ocular involvement. RESULTS: ocular complications were found in 30.65% of the leprosy patients; lagophthalmos (17.74%) was the most frequent followed by uveitis (8.60%). Most of the patients having visual loss had it due to corneal complications and none of the patients with uveitis had vision <6/18. The patients released from treatment (83.33%) and those currently on treatment (31.63%) had higher occurrence of complications. Risk factors for ocular involvement were higher bacillary index, longer disease duration (p-=0.031, RR=1.109, 95% CI=1.009-01.218) and decreased corneal sensation(p=0.001, RR=3.564; 95 % C I=2.014-6.306). Higher Schirmer values (p=0.012, RR=0.935, 95% CI=0.888-0.985) were found to be protective for ocular complications. STASTICS: SPSS ver 10.0 was used for data analysis. The P value of <0.05 was considered as significant. CONCLUSIONS: the prevalence of complications is high in patients released from treatment for leprosy. Cornea-related complications are the most important cause of visual disability and blindness. Risk factors for ocular complications are higher bacillary index, longer disease duration and decreased corneal sensation.

Recent advances in ocular leprosy.

Proper MDT soon after detection of leprosy and anti-reaction measures with newer steroids, regular supervision and monitoring of those released from treatment (RFT) reduce the incidence of ocular leprosy to a remarkable extent. Today, most eye complications are because of normal ageing process or of other phenomena in normal healthy population. Cataract and lagophthalmos are the main causes of blindness. However, in India, though the rate of cataract surgical coverage is up to the mark, the same for lagophthalmos is lagging far behind. Integration of management of ocular leprosy into community eye health care service is the talk of the day along with other health care facilities delivered to people affected with leprosy (PAL). Routine eye examinations are necessary for all PB and MB patients, as well as for the RFT persons in order to detect and treat eyes that are at high risk. All eye surgeries can be performed when needed, irrespective of deformities and bacteriological status, by latest microsurgical techniques with good outcome, and better rehabilitation measures. Reorientation training in ocular leprosy is the immediate special need for ophthalmologists, paramedical ophthalmic assistants and eye health care managers working in general hospitals in those areas that were previously "leprosy endemic zones".

Vitiligo: a part of a systemic autoimmune process.

BACKGROUND: Recent clinical and animal experimental studies postulate that the pathogenetic mechanisms of vitiligo could be of systemic origin as vitiligo is associated with ocular and auditory abnormalities as well as other autoimmune disorders.Hence, we studied genetic factors, systemic associations, ocular and auditory abnormalities of vitiligo. METHODS: The study group included 150 new cases of various types of vitiligo. One hundred age- and sex-matched nonvitiligo cases were included as controls in the study. A complete family history was taken for all patients. Examination was carried out taking note of the type of vitiligo and approximate percentage of body surface involved. All relevant laboratory investigations, a thorough audiological examination including pure tone audiometry and a complete ophthalmologic examination were carried out in all patients and controls. Statistical analysis was done using the Chi square test. RESULTS: Fifty-four vitiligo patients (36%) had a family history of vitiligo. Anemia was present in 30 (20%) vitiligo patients but only in five (5%) controls, a difference that was statistically significant (c2 = 15.8, P < 0.001). Diabetes mellitus was present in 24 (16%) vitiligo patients and only 2 (2%) of controls (Chi square, c2 = 12.4, P < 0.001). Hypothyroidism and alopecia areata were present in 18 (12%) and 11 (7.4%) vitiligo patients respectively and none of the controls. Hypoacusis was seen in 30 (20%) vitiligo patients and two (2%) controls (c2 = 8.19, P < 0.005). Twenty-four vitiligo patients (16%) and five controls (5%) had specific ocular abnormalities like uveitis, iris and retinal pigmentary abnormalities (c2 = 7.39, P < 0.001). CONCLUSION: This study demonstrates statistically significant clinical evidence confirming that vitiligo is a part of systemic autoimmune process.

Patterns of ocular morbidity and blindness in leprosy--a three centre study in Eastern India.

BACKGROUND: Eye disease and visual impairment due to leprosy are not uncommon, but their prevalence and the risk factors for such pathology have yet to be fully characterized. METHODS: An observational study of leprosy-affected individuals in the community, in three districts in Eastern India was performed to determine the prevalence of ocular morbidity and blindness. The subjects were chosen by stratified random sampling, according to stage of treatment, or stage of post-treatment surveillance. Each subject underwent ophthalmic examination according to a standard pro-forma. RESULTS: Thirty-three out of 1137 (2.9%) subjects were blind according to the WHO classification, and 232/1137 (20.7%) had moderate visual impairment. The prevalence of blindness and visual impairment was greatest in one centre, Jhalda. Multivariate Logistic Regression analysis showed that longer duration of disease, more advanced treatment stage and older age were independently associated with blindness. One hundred and forty-one cases (28%) in Muzaffarpur, 95 cases (63%) in Saldoha and 378 cases (78%) in Jhalda had active or treated multibacillary leprosy. DISCUSSION: The prevalence of blindness in leprosy varies in different population groups, with differing patterns of leprosy-related ocular morbidity, blindness and disease type evident even in different areas of the same region. Leprosy screening and surveillance programmes should include ocular examination as part of routine screening, particularly in individuals with a history of multi-bacillary disease. Individuals with known sight- threatening pathology should undergo continued active follow up. Local epidemiological studies would enable appropriate programme planning and efficient allocation of resources.

Ocular leprosy in Nigeria: a survey of an Eku leprosorium.

To determine the ocular morbidity, visual disability and potential for blindness in leprosy patients recently released from treatment. In-patients from Eku leprosy settlement were interviewed and examined for ocular disease from leprosy and other causes. They were examined using the Snellen's chart, pentorch, Kowa portable slit-lamp, direct ophthalmoscope and the pulsair non-contact tonometer. The patients were also refracted. In all, 60 inpatients who were recently released from treatment, comprising 39 men (65%) and 21 women (35%), were examined. Fifty-eight patients (96.67%) had ocular symptoms, the most common being blurred vision in 23 patients (38.33%). Nine patients (15%) were blind. Cataract was the most common cause of blindness occurring in three of the nine patients (33.33%). The most common types of ocular lesions were madarosis (31.67%), lagophthalmos (16.67%) and cataract (16.67%). Potentially blinding conditions due to leprosy were seen in 42 patients (70%). The incidence of ocular involvement, blindness and potentially blinding conditions are high in leprosy patients recently released from treatment. Regular ophthalmic evaluation and integration into Vision 2020 programmes are recommended.

[Frequency of ocular changes in patients with Hansen's disease living in a colony hospital]. / Freqüência das alterações oftalmológicas em pacientes com hanseníase residentes em hospital-colônia.

PURPOSE: To identify the frequency of ocular changes in patients with Hansen's disease, living in a colony hospital; to confirm the predilection for the anterior segment of the eye instead of the posterior segment. METHODS: Transversal study of 115 eyes of 58 in-patients at João Paulo II colony, Marituba-Pará, from August to October 1999. The epidemiologic data of this research were obtained from the patients' charts and from information obtained at clinical eye examination. All patients in this study were considered cured of Hansen's disease according to the Health Ministery criteria of cure. RESULTS: In 114 eyes (99.1%) ocular involvement was observed, the majority (77.2%) being the virchowian form. The most frequent ocular findings in the adnex were parcial madarosis (70.4%) and parcial eyebrow madarosis (59.1%). The most frequent ocular finding related to Hansen's disease was the decrease and/or absence of corneal sensitivity observed in 42.6% of the eyes, followed by paralytic midriasis (16.5%) found in the patients after surgery for cataract extraction; this finding was closely related to iris atrophy (8.7%), commonly found in these patients. CONCLUSION: The high prevalence of ocular involvement in Hansen patients, especially in virchowian form, indicates the need of complete assistance to these patients even after the resolution of the disease.

Freqüência das alterações oftalmológicas em pacientes com hanseníase residentes em hospital-colônia / Frequency of ocular changes in patients with Hansen's disease living in a colony hospital

OBJETIVOS: Identificar a freqüência das alterações oculares em pacientes hansenianos residentes em hospital-colônia; comprovar a predileção pelo segmento anterior do olho em relação ao posterior. MÉTODOS: Fez-se estudo transversal de 115 olhos de 58 pacientes internados no abrigo João Paulo II, em Marituba - Pará, no período de agosto a outubro de 1999. Os dados epidemiológicos da pesquisa foram obtidos da ficha de cada paciente e de dados colhidos durante o exame oftalmológico. Todos os pacientes estudados estavam curados da hanseníase segundo as normas do Ministério da Saúde. RESULTADOS: Em 114 olhos (99,1 por cento) foi observado envolvimento ocular, sendo a maioria (77,2 por cento) pertencente à forma virchowiana. Os achados oculares mais freqüentes nos anexos oculares foram a madarose ciliar parcial (70,4 por cento) e a madarose superciliar parcial (59,1 por cento). Quanto ao bulbo ocular, o achado mais freqüente relacionado à hanseníase foi a diminuição e/ou ausência de sensibilidade corneana observada em 42,6 por cento dos olhos, seguida da midríase paralítica (16,5 por cento) encontrada no pós-operatório dos pacientes submetidos a facectomia, achado ligado intimamente à atrofia de íris (8,7 por cento), comumente observada nestes pacientes. Não foi encontrada nenhuma alteração à fundoscopia que pudesse ser atribuída à hanseníase. CONCLUSÕES: A alta prevalência de alterações do bulbo ocular e anexos em pacientes portadores de hanseníase, principalmente na forma virchowiana, indicam a necessidade da assistência contínua a esses pacientes mesmo após a cura da doença.

Ocular findings in leprosy patients in Nepal in the era of multidrug therapy.

PURPOSE: Detailed ophthalmic evaluation was performed to determine the prevalence of ocular complications among leprosy patients on multidrug therapy and those released from multidrug treatment. DESIGN: Observational case series. METHODS: Leprosy patients at Tribhuvan University Teaching Hospital from April 1, 2001, through September 30, 2002, underwent detailed ophthalmic evaluation including slit-lamp biomicroscopy, dilated funduscopy, and applanation tonometry. RESULTS: We evaluated 58 leprosy patients. A majority (72%) was receiving treatment for multibacillary leprosy; 14% belonged to posttreatment multibacillary and paucibacillary groups. Ocular involvement was found in 57% of patients. In the multibacillary group, 55% had ocular involvement, which was more than double that found in the paucibacillary group (25%), although this finding was not statistically significant (P =.187). Among patients with ocular complications, 48% had visual disability and another 45% had threatened vision; 9% met World Health Organization guidelines for blindness. Uveitis and its complications were the predominant causes of visual disability (88%). CONCLUSION: Ocular complications and visual disability are high among leprosy patients in Nepal even after completing multidrug therapy.

Eye disease in multibacillary leprosy patients at the time of their leprosy diagnosis: findings from the Longitudinal Study of Ocular Leprosy (LOSOL) in India, the Philippines and Ethiopia.

Existing prevalence surveys do not provide adequate information to estimate the magnitude of ocular pathology or vision loss in leprosy patients. We sought to determine the prevalence of ocular findings and related risk factors in leprosy patients at the time of their disease diagnosis. We also sought to determine if there were geographic differences and whether these were due to different demographic characteristics of the populations. The study was undertaken at Schieffelin Leprosy Research & Training Centre (Karigiri, India), Leonard Wood Memorial Leprosy Institute (Cebu, Philippines), and (for 3 years only) ALERT (Addis Ababa, Ethiopia). Newly diagnosed multibacillary (MB) leprosy patients as well as MB cases relapsed after dapsone monotherapy were eligible for enrollment. In each study site, the target population was 300. Standardized examinations were conducted between 1991 and 1998. Patient enrollment included 301 patients in Karigiri, 289 patients in Cebu, and 101 patients in Addis Ababa. The age-adjusted prevalence of blindness (< 6/60 in the better eye) and visual impairment (6/24-6/60) was 2.8% and 5.2%, respectively. Lagophthalmos and leprosy related uveal changes were detected in 3.3% (95% CI 2.0-4.7%) and 4.1% (95% CI 2.4-5.7) of patients, respectively. Overall, 11% (95% CI 8.5-13.2%) of newly enrolled MB patients had potentially blinding leprosy related ocular pathology. Lagophthalmos was associated with increasing age, a short duration between onset and diagnosis, and a previous reaction involving the face. Uveal conditions were associated with increasing age. Overall, eye disease was more common in Indian and Ethiopian patients compared to Filipino patients; however, differences were not significant when controlling for age and clinical (non-ocular) factors. Patients with potentially blinding leprosy related pathology were over three times more likely to have other (hand and foot) disabilities than patients without pathology. Differences in the prevalence of blindness and potentially blinding leprosy related ocular pathology between the sites could be accounted for by the differences in age and other clinical factors of the patients at the different sites. Findings suggest that, even in the face of active leprosy control efforts, around 11% of patients will have potentially blinding pathology at the time of their diagnosis and 2.8% will be blind. If those patients with lagophthalmos or blindness are considered appropriate for referral for more detailed assessment, approximately 4% of newly diagnosed leprosy patients will require active follow-up for eye care; including those with reaction involving the face will result in 9.4% of patients requiring active follow-up. These people are likely to be older, with a reaction involving the face, and/or with other disabilities than those not requiring active follow-up.
