Patients were considered to have MacTel 2 in the presence of findings such as reduced autofluorescence in the central macula on fundus autofluorescence; loss of retinal transparency, intraretinal pigment, presence of right-angle venules, and telangiectatic vessel appearance on fundus examination; and OCT showing interior limiting membrane drape, retinal pigment epithelium migration creating intraretinal hyperreflectivity, atrophy of the outer retinal layers, and presence of intraretinal hyporeflective cavitation.
All of the data point to one conclusion--that the combination of lutein, zeaxanthin, and, ideally, mesozeaxanthin has real effectiveness at restoring the eye's natural blue light shield, the macular pigment epithelium, which should protect against progression of age-related macular degeneration.
Anatomical alterations in colobomatous eyes such as retinal thinning, staphylomatous and thinned sclera and involvement of disc and macula as well as lack of choroid and retinal pigment epithelium makes the surgery technically difficult and therefore the prognosis is less satisfactory3,4.
Optical coherence tomography revealed macular atrophy of the right eye, and retinal pigment epithelium thickness and mild detachment in the macula of the left eye.
These were characterized by absence of pigmentation in retinal pigment epithelium and in choroid, causing white sclera to become visible between choroidal blood vessels.
