ABSTRACT
OBJETIVOS: Avaliar a correlação entre as hemorragias peripapilares (HPPs) e a posição do tronco vascular na cabeça do nervo óptico. MÉTODOS: Retinografias de 1.830 pacientes foram revisadas. A posição do tronco vascular retiniano (TVR) foi classificada de acordo com sua localização no hemisfério superior ou inferior e sua posição relativa através da razão entre a distância entre o TVR e o ponto mais inferior do disco óptico e o diâmetro vertical do disco óptico (razão tronco/disco). Pacientes da mesma população, com glaucoma e sem HPPs foram aleatoriamente selecionados para comparação. RESULTADOS: Dos 1.830 pacientes, 46 apresentaram HPPs. Foram detectadas 53 hemorragias em 41 pacientes com glaucoma ou suspeitos de glaucoma, principalmente na região temporal inferior (47,2 por cento). Observou-se concordância negativa entre a localização superior ou inferior do TVR e das HPPs (Kappa= -0,34). Considerando a posição relativa do TVR em relação ao diâmetro vertical do disco óptico (razão tronco/disco), encontramos melhor correlação (valores médios da razão tronco/disco: 0,450-hemorragias superiores e 0,510-hemorragias inferiores; p=0,027). No grupo com HPPs, observamos porcentagem significativamente maior de pacientes com glaucoma de pressão normal (GPN) se comparado ao grupo sem hemorragia (p=0,009). CONCLUSÃO: HPPs foram mais comuns no hemisfério oposto ao da emergência do TVR. Observamos maior prevalência de GPN nos pacientes com hemorragias que nos sem hemorragia.
PURPOSE: To investigate the correlation between optic disc hemorrhages (ODHs) and the position of the central retinal vessel trunk (RVT) in patients with glaucoma. METHODS: Fundus photographs of 1,830 participants were reviewed. The exit position of the central retinal vessel trunk was classified as being in the superior or inferior hemisphere of the optic disc and the relative vertical position was expressed as a fraction of the disc diameter (ratio between the position of the trunk and the diameter of the disk). A group of patients from the same population, but without ODHs, was randomly selected and compared with the patients with ODHs. RESULTS: Among the 1,830 patients, 53 hemorrhages were detected in 41 patients with glaucoma or suspected glaucoma. We found an inverse relationship between the inferior/superior position of the central RVT and the inferior/superior position of the hemorrhages (Kappa= -0.34). Using the trunk/disc ratio, we found that superior ODHs correlated with inferior RVTs (trunk/disc ratio, 0.450; SD=0.070) and inferior ODHs correlated with superior RVTs (trunk/disc ratio, 0.510; SD=0.054) (p=0.027). The number of patients with normal tension glaucoma was significantly higher among patients with ODHs than among those without ODHs (p=0.009). CONCLUSION: Our patients had a negative correlation between the position of central RVT and the location of the ODHs. Normal tension glaucoma was more prevalent among patients with ODHs than among those without it.

Corneoscleral cysts are a rare entity. We report a case of spontaneous corneoscleral hematic cyst, which was treated by cyst excision and lamellar corneal patch graft. No recurrence of cyst was noticed during the 6 years of followup.
