Frequency of Lattice Degeneration in one eye of the patients with Rhegmatogenous Retinal Detachment.

Objective: We carried out this study to analyze and tabulate frequency of lattice degeneration in the fellow eye ofpatients with Rhegmatogenous Retinal DetachmentMethodology: This prospective cross-sectional study was conducted in Department of Ophthalmology, Civil Hospital,Karachi. All participants aged between 18 to 60 years with rhegmatogenous retinal detachment of either gender, wereenrolled through non probability consecutive sampling. Demographic details included age, gender, height, weight andBMI. Lattice degeneration was labeled as positive based on presence of one or more of the following features whichincludes retinal thinning with round, oval, or linear outlines, pigment changes, yellow-white flecks, white patches, redcrater-type spots, small atrophic holes, branching white lines, and scattered yellow atrophic areas. Rarely, tractionaltears occur near the ends or back margins of these lesions.Results: Amongst the 98 patients, the mean age was 51.72 ±3.69 years. There were 68 (69.4%) females. Decreasedvision as presenting symptoms was reported by 54 (55.2%) participants, flashes of light by 39 (39.8%) and peripheralshadow by 21 (21.4%) patients. The frequency of lattice degeneration was observed in 33 (33.7%) patients. Statisticallysignificant correlation was found between symptoms and age groups with the presence of lattice degeneration in felloweyes (p<0.05).Conclusion: The frequency of lattice degeneration was observed in one third of the fellow eye of patients with rhegmatogenousretinal detachment. Hence, driving the need for correct and vigilant screening on first presentation to preventany irreversible complications.
