Prevalence of lattice degeneration is maximum in axial length between 28-30mm (8).
The decision to treat or not to treat lattice degeneration prophylactically to prevent RD is complicated.
Untreated U-tears in lattice degeneration need urgent attention, preferably within 24 hours Atrophic holes within lattice degeneration do not require treatment, so no referral is necessary as a rule, but non-urgent referral is advisable if the patient has presented with symptoms of posterior vitreous detachment (floaters, photopsia).
It is this combination (thin retina, strong vitreous attachment and a reservoir of liquefied vitreous) that makes lattice degeneration a risk factor for tractional tears following PVD.
