RESUMO
To evaluate epidemiology of retinal and choroidal diseases and to calculate the Foveal Avascular Zone(FAZ), diameter and its variation with different diseases and analyse its impact on BCVA(Best corrected visual acuity) using Fundus fluorescein Angiography as diagnostic tool. Materials and methods: The study was conducted in 100cases of retinal and choroidalpathologies undergoing FFA Out of 100 patients maximum were in the age group 50-60 yrs with Diabetic Retinopathy as maximum incidence. FAZ in within normal eyes were in the range of 0.400mm-0.500mm while it increased in Diabetic retinopathy, BRVO,CRAO and hypertensive retinopathy. Eyes with larger FAZ had lower BCVA.
RESUMO
A case of dermoid cyst with intracranial extension in a 10-year-old boy is reported. Intracranial extension of dermoid is not very common.
