Poppers maculopathy: A quantitative review of previous literature

Abstract

Aim: To review the available literature on poppers maculopathy (PM).Material and methods: 64 patients (60 with bilateral and 4 with unilateral involvement), for a total of 124 eyes reported in Pubmed, Google Scholar and Embase. Patterns were analyzed according to country, age, gender, sexual orientation, HIV status, consumption habits, visual acuity at presentation (VAP), final visual acuity (VAF) and optical coherence tomography (OCT).Results: Most cases (110 eyes) of PM were reported in European countries and affected middle-aged men (only 8 eyes from female users). The median age was 38.7 years (SD=10.5 years). Final visual acuity (Median=0.8; Interquartile range: 0.67-1) was higher than visual acuity at presentation (Median=0.67; Interquartile range: 0.4-0.8). Many articles lack data on sexual orientation and HIV status as this is considered very personal information. VAF was higher than VAP. One third of the eyes (40 eyes) developed PM after a single exposure. No significant differences were found between eyes that developed PM after a single exposure and those which developed the condition after several exposures. The most commonly reported pattern was an interruption of the ellipsoid line (68 eyes).Conclusion: PM is more prevalent in Europe or European ophthalmologists are more likely to diagnose PM. PM usually affects middle-aged men given that this condition generally appears with chronic exposure to poppers. VAF was higher than VAP, suggesting that this toxicity is in part reversible. Information about HIV status was not provided in most recent articles, thus it is not possible to make inferences about the possible implication of HIV drugs as cofactors for the development of this retinal toxicity.

Die Rolle der optischen Kohärenztomografie bei der Poppers-Makulopathie

“…Differential diagnosis of changes of the EZ particularly include solar maculopathy, cone dystrophies, and adult-onset vitelliform macular dystrophy. In case of small foveal detachment, both age-related macular degeneration and serous central chorioretinopathy should be excluded [3]. can easily cross lipid membranes.…”

“…Zu den Differenzialdiagnosen zählen angesichts der Veränderungen der ellipsoiden Zone vor allem die phototoxische Makulopathie, Zapfen-Dystrophien, sowie die adulte vitelliforme Makulodystrophie. Im Falle geringer seröser fovealer Abhebung sollten insbesondere eine altersbedingte Makuladegeneration sowie Chorioretinopathia centralis serosa ausgeschlossen werden 3 .…”
