Lattice degeneration

Disease
Degenerative conditions involving the peripheral retina may be termed 'predisposing' or 'non-predisposing'. The predisposition is to retinal breaks and detachment. Lattice degeneration falls into the former category and is therefore an important clinical entity, being an equatorial area of retinal thinning and present in about 40 per cent of patients who have detachment of the retina.

Lattice degeneration is usually bilateral and is not age-related, commencing fairly early in life with a maximum frequency around the second decade. There is no gender predilection, with the condition being more commonly encountered in association with moderate myopia. Some studies have suggested there may be some hereditary transmission.

There may be systemic disease associations, with such conditions as Wagner's disease, and Stickler's, Marfan's, Ehlers-Danlos and Turner's syndromes.

Symptoms

Unless associated with a complicating clinical situation or disease, lattice degeneration of itself is not associated with any visual symptoms.
