Advantages:

Our purpose was to study the clinical course of optic pit maculopathy using spectral optical coherence tomography (OCT) images, and to discuss possible ways of fluid entrance into the subretinal space.

Methods:

11 eyes with a macular detachment in combination with an optic pit were examined using spectral OCT, with axial resolution 3-6µm. In selected cases, fluorescein angiography and scanning laser ophthalmoscopy were also performed.

Effectiveness / Safety:

Spectral OCT enabled exact visualization of retina layers and optic disc in optic pit maculopathy. In all patients, a membrane overlying the optic disc was noted. In one patient, a possible connection between subarachnoid and vitreous space was visualized. It was observed that changes in spectral OCT in the macular region correlated with visual acuity.

Take home message:

According to the presented spectral OCT images, subretinal fluid seems to be rather subarachnoidal than vitreous origin. Analyzing the natural course of macular detachment we observed that fluid initially enters the retinal stroma forming a schizis and then enters the subretinal space creating a less extensive circumscribed detachment of retinal layers. In patients with an interconnection between the subarachnoidal and subretinal space and an disrupted membrane covering the optic disc pit the prognosis is worse.
