ABSTRACT
ABSTRACT Purpose: The study aimed to describe anatomic and visual outcomes associated with perfluoropropane intravitreal injection followed by laser treatment for macular retinal detachment secondary to optic disc pit. Methods: A single-center, retrospective study. Medical records of all patients treated at a tertiary retina referral center were evaluated between 2011 and 2018 for congenital optic disc pit-associated macular detachment with 0.3 ml 100% perfluoropropane intravitreal injection followed by retinal laser photocoagulation along the temporal optic disc margin as the initial treatment. Results: Six patients with optic disc pit-associated macular detachment were identified, with postoperative follow-up ranging from 13 to 52 months (mean: 28 months). Spectral domain optical coherence tomography (SD-OCT) showed complete fluid resolution without recurrence in five of the six cases. Four cases showed complete reabsorption after Intravitreal perfluoropropane plus laser, one patient needed an extra procedure (pars plana vitrectomy with inner limiting membrane peeling and pedicle flap inversion over the temporal optic disc margin) to achieve complete fluid reabsorption, and one patient had persistent intraretinal fluid and denied additional surgeries. The time between the initial procedure and total fluid reabsorption varied from 6.5 to 41 months (mean: 19.5 months). Best-corrected visual acuity improved after surgery on the last follow-up visit in all cases. Conclusion: 100% perfluoropropane intravitreal injection followed by photocoagulation along temporal optic disc margin was associated with anatomic and visual improvement in most cases, representing an alternative treatment approach for optic disc pit-associated macular detachment.
RESUMO Objetivo: Descrever os resultados anatômicos e visuais associados à injeção intravítrea de perfluoropropano seguida de tratamento a laser para descolamento de retina macular secundário à fosseta do disco óptico. Métodos: Estudo retrospectivo em um único centro. Foram revisados os prontuários médicos dos pacientes com descolamento macular associado a fosseta do disco óptico congênito em um centro de referência terciário de retina entre 2011 e 2018. Todos receberam como estratégia de tratamento inicial injeção intravítrea de perfluoropropano 100% seguido por fotocoagulação a laser ao longo da margem temporal do disco óptico. Resultados: Foram identificados seis pacientes com descolamento macular associado a fosseta do disco óptico durante o período do estudo. O seguimento pós-operatório variou de 13 a 52 meses, com média de 28 meses. SD-OCT demonstrou resolução completa do fluido em cindo dos seis casos, sem recorrência. Quatro casos apresentaram reabsorção completa após perfluoropropano intravítreo associado a laser, e um paciente necessitou de procedimento adicional (vitrectomia via pars plana com peeling da membrana limitante interna e inversão do retalho do pedículo sobre a margem temporal do disco óptico) para obter reabsorção completa de fluidos. Um paciente apresentou fluido intrarretiniano persistente e negou tratamentos adicionais. O tempo entre o procedimento inicial e a resolução completa do fluido variou entre 6,5 a 41 meses, com média de 19,5 meses. A acuidade visual corrigida melhorou após a cirurgia, considerando a última consulta de acompanhamento em todos os casos. Conclusão: A injeção intravítrea de perfluoropropano 100% seguida de fotocoagulação ao longo da margem temporal da margem do disco óptico foi associada à melhora anatômica e visual na maioria dos casos e representa uma abordagem terapêutica alternativa para o descolamento macular associado a fosseta do disco óptico.
ABSTRACT
Objective@#To investigate the successful signs of laser photocoagulation or endolaser combined vitrectomy for congenital optic disc pit (ODP) with serous macular detachment.@*Methods@#A retrospective case analysis. Twelve eyes of 12 patients with congenital ODP complicated with serous macular detachment diagnosed in Zhongshan Ophthalmic Center from 2003 to 2018 were included in this study. There were 2 males (2 eyes) and 8 females (8 eyes). The average age was 30.17 years old. Retinal laser photocoagulation and/or vitrectomy were performed in all the eyes. The optic disc and macular area were scanned using the tracking mode of the Germany Heidelberg Spectralis OCT instrument. The "dam-sign" change was a retinal choroidal scar on the channel between the ODP and the macula on the OCT image after treatment. The eyes were divided into a "dam-sign" change group (group A, 10 eyes) and no "dam-sign" change group (group B, 2 eyes). The BCVA of eyes in group A was 0.03-0.6. In group A, 1 eye was treated with laser photocoagulation alone, 9 eyes were treated with vitrectomy combined with laser photocoagulation. The BCVA of eyes in group B was 0.1. All the eyes in group B underwent vitrectomy combined with laser photocoagulation. The follow-up was ranged from 6 to 174 months. The same equipment and method before treatment were used for 1, 3, 6, 12, 18, and 24 months after treatment. The BCVA, absorption of subretinal fluid (SRF) and the formation of "dam-sign" change were observed.@*Results@#At the last follow-up, the BCVA of eyes in group A was 0.4-1.0 (0.4 in 1 eye, 0.5 in 3 eyes, 0.6 in 2 eyes, 0.8 in 3 eyes, 1.0 in 1 eye). In 9 eyes treated with vitrectomy combined with laser photocoagulation, SRF was completely absorbed. In 1 eye treated with laser photocoagulation alone, SRF remained in small amount. The BCVA of the two eyes in group B was 0.03 and 0.3, respectively; and SRF was not absorbed in both of them.@*Conclusions@#The "dam-sign" change near optic disc after laser photocoagulation can promote SRF absorption and improve BCVA. It can be used as a success indicator after treatment.

ABSTRACT
ABSTRACT Purpose: To evaluate the central corneal thickness (CCT), corneal volume (CV), and anterior and posterior corneal surfaces using the Scheimpflug imaging system in patients diagnosed with tilted disc syndrome (TDS). Methods: The study group (Group 1) and the control group (Group 2) comprised 35 eyes of 35 age-, sex-, and refraction-matched cases. All cases underwent a full ophthalmic examination that included cycloplegic refraction, axial ocular length measurement, and Scheimpflug imaging. Results: The mean age was 34.68 ± 15.48 years in Group 1 and 34.11 ± 12.01 years in Group 2 (p=0.864). The gender distribution was 18 males and 17 females in Group 1 and 16 males and 19 females in Group 2 (p=0.618). All subjects were Caucasian. The spherical equivalent was 3.62 ± 1.75 D in Group 1 and 3.69 ± 1.51 D in Group 2 (p=0.850). There was no significant difference in age, sex, race, or spherical equivalent between groups. There was no significant difference in mean keratometric value and CV3 (the CV in the central 3 mm) between groups (p=0.232 and 0.172, respectively). There were statistically significant differences in CCT, CV5, and CV7 (CV in the central 5 and 7 mm3, respectively) and total CV between groups (p=0.008, 0.003, 0.023, and 0.019, respectively). The values of all parameters were lower in the study group than in the control group. There was also a statistically significant difference in the anterior elevation parameters of the cornea between groups (p<0.05). The mean values of Group 1 were higher than those of Group 2. There were statistically significant differences in the two parameters referring to the posterior elevation of the cornea between the two groups (p<0.05). Conclusion: The results of this study showed that eyes with TDS have thinner CCT, lower CV, and different anterior corneal curvature than normal eyes.
RESUMO Objetivo: Avaliar a espessura central da córnea (CCT), o volume de córnea (CV), e a superfície corneana anterior e posterior utilizando sistema de imagem Scheimpflug em pacientes com diagnóstico de síndrome do disco inclinado (TDS). Métodos: O grupo de estudo (grupo 1) e o grupo controle (grupo 2) consistiu de 35 olhos de 35 pacientes pareados por idade, sexo e refração em cada grupo. Todos os casos foram submetidos a um exame oftalmológico completo incluindo refração sob cicloplegia, medida do comprimento axial ocular e avaliação por Scheimpflug. Resultados: A idade média foi de 34,68 ± 15,48 anos no grupo 1 e 34.11 ± 12,01 anos no grupo 2 (p=0,864). A distribuição por sexo foi de 18 homens e 17 mulheres do grupo 1 e 16 homens e 19 mulheres no grupo 2 (p=0,618). Todos os indivíduos eram caucasianos. O equivalente esférico foi 3,62 ± 1,75 D no Grupo 1 e 3,69 ± 1,51 D no Grupo 2 (p=0,850). Não houve diferença significativa entre os dois grupos para idade, sexo, raça e equivalente esférico. Não houve diferença significativa entre os dois grupos para o valor médio ceratométrico e CV3 (o volume da córnea na central 3 mm) (p=0,232, p=0,172, respectivamente). Houve diferença estatisticamente significativa entre os dois grupos para CCT, CV5, CV7 (volume de córnea na região central 5 e 7 mm, respectivamente) e CV total (p=0,008, p=0,003, p=0,023 e p=0,019, respectivamente). Os valores do grupo de estudo foram menores do que o grupo controle para todos os parâmetros. Houve também diferença estatisticamente significativa entre os dois grupos nos parâmetros elevação anterior da córnea (p<0,05). Os valores médios do grupo 1 foram maiores do que o grupo 2. Não houve diferença entre os dois grupos para os dois parâmetros referentes à elevação posterior da córnea (p<0,05). Conclusões: Nosso estudo mostrou que os olhos com TDS apresentam CCT mais fina, menor volume da córnea e alterações na curvatura corneana anterior quando comparados aos olhos normais.
