White Retina

Incidence increases with age and increased axial length
𝐀𝐩𝐩𝐞𝐚𝐫𝐚𝐧𝐜𝐞:
● Translucent white- gray appearance of the equator/ peripheral retina seen without scleral depression
● Bilateral, Maybe circumferential
● Bounded posteriorly by reddish brown line
● Sharply demarcated margins
● Misdiagnosed as retinal detachment/retinoschisis
● Scleral indentation reveals that retina is opposed to underlying RPE
● May have scalloped borders (sign of possible progression), migratory in nature
● The size, shape and location of WWOP might change over time
𝐀𝐬𝐬𝐨𝐜𝐢𝐚𝐭𝐢𝐨𝐧𝐬:
● Maybe associated with lattice degeneration/ snowflake degeneration
● Associated with vitreous degeneration and PVD
● Horseshoe or linear tears can develop along posterior order of WWOP due to traction of PVD
● Vitreoretinal traction is known to be associated with WWOP and is strongly implicated in the genesis of retinal tears and subsequent retinal detachments
𝐂𝐨𝐧𝐭𝐫𝐢𝐛𝐮𝐭𝐢𝐧𝐠 𝐟𝐚𝐜𝐭𝐨𝐫𝐬 𝐭𝐨 𝐭𝐡𝐞 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐨𝐟 𝐫𝐞𝐭𝐢𝐧𝐚𝐥 𝐛𝐫𝐞𝐚𝐤𝐬:
● Presence of lattice degeneration
● Scalloped borders (suggesting progression over time)
● Shrinkage of the vitreous
● Elevated tractional membrane
𝐅𝐨𝐥𝐥𝐨𝐰 𝐮𝐩:
● Patients with this condition should know that it carries a low risk for complications but that it is important to report symptoms or signs of traction and breaks immediately
● Follow up at 1- to 2-year intervals, depending on the presence of other associated risk factors.
● The patient should be reexamined every 6 months if the posterior borders of the WWOP are scalloped and there is extensive vitreous degeneration
