A congenital anomaly, optic nerve pit is often associated with serous retinal detachment involving macula. Long standing serous detachment leads to outer retinal atrophy and decrease in visual sensitivity. Recently, spectral-domain optical coherence tomography (OCT) has been reported to demonstrate a communication between the optic nerve sheath and the subretinal space. Vitreous cavity is propo...
Seventeen patients with central retinal vein occlusion aged 40 or under were reviewed. Ocular involvement was characteristically unilateral, with moderate degrees of retinal haemorrhage, little retinal ischaemia, and a tendency to optic disc swelling. Visual prognosis was good. Follow-up showed that most patients have good general health and no involvement of the fellow eye. There was little ev...

anterior megalophthalmos is a developmental anomaly of the anterior ocular segment. this is an x-linked recessive disease and manifests as bilateral enlarged corneas, open iridocorneal angle, hypoplastic iris and dislocation and opacification of an apparently small lens. we have also observed obvious vitreoretinal degeneration in our patients. what may threaten visual acuity later is an open an...

MGS is an uncommon congenital optic disc anomaly, which was first described by Kindler [1]. It is characterized by an enlarged funnel-shaped dysplastic disc with glial tissue. The retinal vessels are increased in number, appear to arise from the disc edge and run an abnormally straight course over the peripapillary retina [2,3]. Retinal detachment may occur in about one-third of cases of MGS [4...
