ABSTRACT

PURPOSE: To investigate a possible microvascular component of poppers maculopathy (PMP) using optical coherence tomography angiography (OCTA). METHODS: Twelve patients suffering from poppers maculopathy were included. Health records, optical coherence tomography (OCT), and OCTA data was gathered and compared to a healthy control group (HC). PMP lesion type was determined by manifestation in OCT. OCTA-based evaluation of retinal vascular plexus and choriocapillaris (CC) was executed. Vessel density (VD) and vessel length density (VLD) in superficial and deep capillary plexus (SCP, DCP), as well as flow deficits (FD), within the foveal avascular zone (FAZ) in CC were assessed. RESULTS: Median age of PMP patients was 40 (min 24; max 64) years, all male. Eleven patients presented with ellipsoid zone-type lesions; one patient showed a vitelliform-type lesion. No qualitative microvascular changes between PMP patients and HC were identified. Quantitative values for VD and VLD of SCP and DCP did not differ in between the two groups. The analysis of FDs in CC showed no deviation from PMP patients to HC. CONCLUSIONS: No vascular anomalies in qualitative and quantitative analysis in OCTA were detected in PMP patients. The constitution of the CC within FAZ of PMP patients does not differ from HC when assessed as FD.

ABSTRACT

Background Torpedo maculopathy is a very rare, congenital, usually unilateral hypopigmented lesion in the temporal macula. Material and Methods This retrospective case series describes three patients with torpedo maculopathy. Results The first two cases demonstrate typical clinical and imaging findings of torpedo maculopathy in asymptomatic patients. The third case relates to a symptomatic young patient with a torpedo lesion, a smaller satellite lesion, and evidence of choroidal neovascularization confirmed by fluorescence angiography. In the area of the clinically visible torpedo lesion, spectral domain optical coherence tomography showed atrophy of the outer retina with increased choroidal signalling and a hyperreflective lesion above the retinal pigment epithelium suggestive of choroidal neovascularization. Fundus autofluorescence imaging revealed a hyperautofluorescent rim along the margin of the hypoautofluorescent torpedo lesion. Conclusion In the literature, torpedo lesions are usually regarded as benign lesions with no tendency for progression. The third case demonstrates that torpedo lesions may be associated with choroidal neovascularization, which has been successfully treated with anti-VEGF therapy.
