ABSTRACT
Purpose: This study aimed to compare the conventional eye patch with Occlu?tab—a binocular open?type amblyopia training device—and evaluate their effectiveness in amblyopia treatment. Methods: In this prospective, multi?center study, 40 patients between ages 3 to 12 years, diagnosed with anisometropic amblyopia (refraction difference of both eyes ? 2 D, best?corrected visual acuity [BCVA] of the amblyopic eye ? 0.1 [logMAR]) were treated with Occlu?tab or conventional eye patch for 1 h per day thrice a week. We compared the visual acuity of both groups before and after 6, 7, and 8 weeks of amblyopia treatment. One?way repeated?measures analysis of variance and Tukey’s test were used to compare the visual acuity of both groups pre? and post?treatment. Results: Both groups had significantly improved visual acuity at 6, 7, and 8 weeks compared to that before treatment (all P < 0.001). The improvement in BCVA of the Occlu?tab group (0.33 ± 0.25) was significantly greater than that of the eye patch group (0.16 ± 0.17) after 8 weeks of treatment (P = 0.02). Conclusion: Amblyopia treatment using binocular open game training with Occlu?tab led to greater improvement in visual acuity than that with a conventional eye patch for the same treatment duration
ABSTRACT
Amblyopia should be treated in early ages to have better outcomes. Stimulation of suppressed eye and depriving light stimulus to the good eye is the main principal of the amblyopia treatment. Adherence to the patching for the treatment of amblyopia in children remains challenging. This could be due to poor cooperation of child or ill-fitting patch. Younger children can be motivated to mimic cartoon figures to improve their adherence to patching. Amblyopia treatment is a team work of parents and optometrist who not only select the mode of management but improve the acceptance of child for patching. We present a child with mild anisometropia and hypermetropia-induced esotropia and amblyopia who was non-compliant to patching. An innovative idea by the parents using a Ninja Turtle patch on the prescribed spectacle was very well accepted by the child and both esotropia and amblyopia improved within four months of the patching treatment. The vision in the affected eye improved from 20/200 to 20/20 with refractive error correction and patching. We share this low-cost child-friendly patching technique that parents invented that can be used to improve adherence to patching by young children during amblyopia therapy. This parent’s innovation enabled to improve adherence and thus address amblyopia in patched eye and regain vision.
ABSTRACT
AIM:To evaluate the clinic efficacy of 1g/L anthocyanin eye-patch for mild and moderate dry eye. METHODS: ln this prospective and multicenter study, a total of 320 cases (640 eyes) with mild and moderate dry eye were enrolled from 8 Aier Eye Hospitals in Changsha, Chongqing, Wuhan and so on from October 2016 to April 2017. The patients were assigned to eye patch group (160 cases) and artificial tears group (160 cases) based on random number table. The patients in eye-patch group used 1g/L of anthocyanin eye-patch for more than 6h during night sleep, while the patients in artificial tears group used polyvinyl alcohol eye drops for 4 times per day. The evaluation of symptoms and signs were conducted on 1d before the treatment and 14d after the treatment. The evaluation of symptoms adopted the Ocular Surface Disease lndex ( OSDI), while the observation of signs included tear secretion test (Schirmer ︳ test, S︳t), first noninvasive tear breakup time (NITBUTf) as well as average noninvasive tear breakup time (NITBUTav) measured by Oculus ocular surface analyser. RESULTS: OSDI score, NITBUTf and NITBUTav in the two groups after treatment were significantly improved compared with that before treatment, and the difference had a statistical significance (P < 0. 05). While the difference of S︳t in the two groups before and after treatment had no statistical significance(P>0.05). There was no significant difference in OSDI score, NITBUTf, NITBUTav and S ︳ t between the two groups after treatment (P>0.05). CONCLUSION: The 1g/L anthocyanin eye-patch has similar efficacy with artificial tears for mild and moderate dry eye, which can effectively improve the symptoms and tear film stability.
