Abstract
Objetivo: Analisar o perfil epidemiológico dos casos de evisceração e enucleação no pronto-socorro oftalmológico de um hospital terciário brasileiro.
Métodos: Análise retrospectiva dos casos tratados no pronto-socorro oftalmológico do Hospital São Paulo (Universidade Federal de São Paulo) entre os anos de 2013 a 2018. Os casos urgentes de evisceração e enucleação foram incluídos e os casos eletivos foram excluídos. A análise dos prontuários médicos foi baseada em: dados demográficos, causas imediatas e associadas ao procedimento, acuidade visual informada, duração dos sintomas antes do atendimento oftalmológico, complicações, distância da residência até o hospital e tempo de hospitalização.
Resultados: 61 enucleações e 121 eviscerações foram incluídas no estudo. Os pacientes tinham uma média de idade de 63,27 ± 18,68 anos; 99 eram do sexo masculino (54,50%) e 83 do sexo feminino (45,60%). As indicações de evisceração e enucleação foram: perfuração corneana com (44,50%) e sem (23,63%) sinais infecciosos, endoftalmite (15,38%), trauma ocular (14,29%), neoplasia (0,55%), queimadura (1,10%) e phthisis bulbi (0,55%). A acuidade visual informada foi de ausência de percepção luminosa (87,36%), percepção luminosa (1.10%), ausência de colaboração (3,30%) e sem dados informados (8,24%). A média de tempo até a busca pelo serviço oftalmológico foi de 18,32 dias. Houve 2 casos de oftalmia simpática após evisceração.
Conclusões: Eviscerações foram predominantemente realizadas em comparação a enucleações em todo o período de estudo. As características demográficas mais comuns foram idade >60 anos e sexo masculino. As principais indicações para procedimentos urgentes de evisceração e enucleação foram perfuração corneana com e sem infecção, endoftalmite e trauma ocular. Este estudo poderia guiar medidas preventivas para evitar procedimentos oculares destrutivos.

Abstract
PURPOSE: To evaluate the effects of a propylene glycol–hydroxypropyl guar nanoemulsion on symptoms and ocular surface parameters in patients with evaporative dry eye.
METHODS: This prospective, single-center, interventional study included patients aged 18–50 years with evaporative dry eye who received a propylene glycol–hydroxypropyl guar nanoemulsion. Participants were instructed to instill the nanoemulsion three times daily for 90 days. Evaluations included the Ocular Surface Disease Index, tear osmolarity, tear meniscus height, lipid layer thickness, noninvasive tear break-up time, fluorescein tear break-up time, corneal fluorescein staining (National Eye Institute Scale), Schirmer’s test I, and meibum quality.
RESULTS: Thirty-three participants were enrolled, and 30 completed the study. The mean age was 36 ± 10 yr, and 73.3% were women. The mean Ocular Surface Disease Index score significantly decreased from 43.1 ± 20 at baseline to 25.2 ± 17 at 3 months (p=0.009). Median corneal fluorescein staining decreased from 2 (IQ range=1–3) to 1 (IQ range 25–75 = 0–1) at the final follow-up (p=0.002). The mean fluorescein tear break-up time increased significantly increased from 3.8 ± 2.1 at baseline to 5.8 ± 2.2 at 3 months (p=0.002). Tear osmolarity decreased significantly (p=0.01) and lipid layer thickness improved markedly (p<0.001). No significant changes were observed in tear meniscus height or noninvasive tear break-up time (p>0.05).
CONCLUSIONS: Treatment with a propylene glycol–hydroxypropyl guar nanoemulsion significantly improved dry-eye symptoms, corneal staining, tear film stability, and lipid layer quality in patients with evaporative dry eye. No adverse events were reported, supporting the safety and efficacy of this formulation.

Abstract
PURPOSE: To evaluate the changes in the rates and indications of eye removal procedures during the recent COVID-19 pandemic.
METHODS: The medical records of all patients who underwent eye removal from 2007 to 2022 were retrospectively reviewed. The patient demographic data and indications for surgery were collected. Data from two groups of patients (prepandemic surgery and postpandemic surgery) were compared. Statistical significance was set at p<0.05.
RESULTS: Fifty-nine patients underwent enucleation (69%), evisceration (27%), or exenteration (3%). The mean (SD) age of the patients was 55.9 (19.4) years, and most (69%) of the patients were males. Most (47%) of the study population were Black. The common indications for eye removal were trauma (41%), painful blind eye (34%), and infection/inflammation (24%). The types of trauma were assault (55%), accidental (39%), and self-inflicted (6%). The mean (SD) monthly rates of eye removal increased from 0.25 (0.50) in the prepandemic period to 0.77 (0.91) during the pandemic (p<0.001). These increases were noted in both males (p=0.003) and females (p=0.001) and were the highest among Black patients [0.42 (0.76); p<0.001]. Among the indications of eye removal, painful blind eyes [0.35 (0.75); p<0.001] and ocular trauma [0.31 (0.47); p=0.051] exhibited the greatest increases following the pandemic.
CONCLUSION: The rate of eye removal procedures increased during the recent pandemic. Although delayed care of chronic eye conditions may have contributed to the increased rates of painful blind eyes, the increased trauma-related eye removals may be attributed to the simultaneous spike in violent assaults in New York City.
