𝘓𝘢𝘵𝘵𝘪𝘤𝘦 𝘋𝘦𝘨𝘦𝘯𝘦𝘳𝘢𝘵𝘪𝘰𝘯 ● Peripheral retinal degeneration with spindle-shaped areas of retinal thinning, most common degeneration to cause retinal detachment ● 8-10% incidence ● Present in 20-30% of Rhegmatogenous RD ● Symmetrical and bilateral, most common superiorly
𝐀𝐩𝐩𝐞𝐚𝐫𝐚𝐧𝐜𝐞: ● Elongated lesions with long axis parallel to the ora serrata, located in the peripheral retina, usually hyperpigmented and mottled looking ● Sclerosed white vessels display criss-crossing pattern - the appearance responsible for the term ‘lattice’ ● Abnormal pigmentation - most common finding - increases with age ● Tiny white or yellow flecks between retinal surface and vitreous cortex 𝐇𝐢𝐬𝐭𝐨𝐥𝐨𝐠𝐲: ● Discontinuity of internal limiting membrane ● Overlying area of liquified vitreous ● Condensation and exaggerated adherence of vitreous gel at margin of lesion ● Atrophy of inner retina 𝐈𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐟𝐨𝐫 𝐭𝐫𝐞𝐚𝐭𝐦𝐞𝐧𝐭: Lattice without retinal breaks - no treatment Lattice with atrophic holes - no treatment Lattice + holes + subclinical RD - barrage laser Lattice + traction tear - treat if fellow eye has RD/ family history of RD/ aphakia Asymptomatic traction tear- no treatment Acute symptomatic tear- treat in phakics and aphakics www.ophthalmobytes.com Image from Rajan Eye Care Hospital #ophthalmology #ophthal #doctor #health #medical #vision #education #optometry #medicalstudent #optometrist #medicine #eye #ophtho #ophthalmologist #ophthalmo #med #medicaleducation #ophthalmologyresident #ophthalmologyresidency #retina #peripheralretina #latticedegeneration #retinaldetachent #RD #retinalbreak #vitreous
