![]() I might be off base but I'm taking a shot! Several hours after removal, my vision returned to normal. When I used them with the standard inserts, they pressed against my eye, similar to the way a compress would. I think it might be the reason I would wake with blurred vision after sleeping in the tranquil eyes goggles. But the short response to your concern is, I suspect, that this is the cornea's natural response to having pressure applied to it. I'm sure someone should be able to give you a more simple explanation. I believe this reflex has to do with the way the cells form a matrix when pressure is applied. The article refers to pressure placed on the cornea by RGP lenses. ![]() They involve Bowman’s membrane and fluorescein collects in the furrows giving the characteristic picture." "Fischer-Schweitzer mosaic This condition is characterised by the appearance of a series of minute lines or furrows giving the impression of a ‘wrinkled’Ĭornea (Figure 1). Here is an article that discusses the Fischer-Schweitzer mosaic : Here is mention of this study in Rebecca's blog: Although there was no correlation between visual degradation and AR, CT, CCC, LLT, or the presence of striae or corneal edema, visual degradation correlated positively with the polygonal reflex, which was observed following warm compress application. CONCLUSIONS.: Warm compress application induces transient visual degradation. The polygonal reflex correlated positively to visual blur (r = 0.88, p = 0.04) and to VA decrease (r = 0.79, p = 0.1). Group 2: Of 11 experimental eyes: 10 exhibited the polygonal reflex compared with 0 controls (p /=2 lines (mean = 2.9 +/- 0.9). The findings for AR, CT, CCC, LLT, striae and edema did not correlate with blur or with VA decline. For the control eye, two subjects reported blur and none exhibited decreased VA. At 30 min: Group 1: Of 13 experimental eyes: 13 experienced subjective blur nine exhibited a VA decrease >/=2 lines (mean = 3.4 +/- 0.7). RESULTS.: At 5 and 30 min, 71% and 88% of all subjects experienced increased subjective blur and decreased VA. Group 2 (n = 11): the above warm compress protocol was repeated to investigate the Fischer-Schweitzer polygonal reflex at the times stated. Striae and edema were assessed for each eye at 30 and 5 min after application. Subjective blur, VA, AR, CT, CCC, and LLT were evaluated for each eye at 5, 15, and 30 min and 5 min after application. A warm, moist compress (44.4-45 degrees C) was applied with gentle pressure for 30 min to the closed eyelids of the randomized experimental eye nothing was applied to the contralateral control eye. Group 1 (n = 13): baseline measurements for each eye included subjective blur, visual acuity (VA), autorefraction (AR), corneal topography (CT), central corneal curvature (CCC), lipid layer thickness (LLT), and evaluation for corneal striae and edema. METHODS.: Subjects (n = 24) with dry eye symptoms were recruited. PURPOSE.: To document adverse visual effects of warm compress therapy and determine potential etiologies in subjects with dry eye symptoms.
