ABSTRACT
Objective:
To screen the retinopathy in HIV/AIDS patients with both non-mydriatic ultra-wide-field (UWF) retinal imaging and mydriatic fundus examinations with the Superfield lens and a slit lamp biomicroscope, and to evaluate the consistency of two methods and provide reference for future clinical screening work and even technological innovation (such as telemedicine screening and artificial intelligence).Methods:
Cross sectional study. One hundred and fifty-eight eyes of 80 HIV-positive patients from the Ophthalmology Department of Beijing Youan Hospital were enrolled in this prospective observational study. All patients underwent comprehensive ophthalmological examination. A single image was obtained from each eye using the UWF fundus imaging system (Daytona, Optos, Dunfermline, UK), and then a dilated fundal examination with the Superfield lens was conducted by another expert. The possible type and location of the lesion with these two methods was recorded respectively. The consistency was compared using the detection rate and Kappa value.Results:
Fifty-two patients (65%) had fundus changes, and 28 patients (35%) were normal. Seventy-nine eyes (50%) were normal and 79 eyes (50%) had fundus lesions. Sixty-one eyes (77.2%) had HIV-related fundus lesions, while 18 eyes (22.8%) had non-HIV-related fundus lesions. Fifty-two eyes (65.8%) suffered posterior or posterior involving lesions, and 27 eyes (34.2%) suffered isolated peripheral lesions. The detection rate of UWF retinal imaging and slit lamp biomicroscopy with the Superfield lens was 17.7% (28/158) and 18.4% (29/158) (P=1.000>0.05) for HIV-related microvascular retinopathy, 8.2% and 8.2% (13/158) (χ(2)=158.00, P=1.000) for cytomegalovirus retinitis (CMVR), 36.1% and 36.1% (57/158) (χ(2)=71.066, P=1.000) for HIV-related fundus lesions, 41.8% (66/158) and 47.5% (75/158) (χ(2)=63.514, P=0.136) for fundus lesions, 33.5% (53/158) and 31.0% (49/158) (χ(2)=108.268, P=0.388) for posterior/posterior involving lesions, and 6.4% (10/158) and 16.5% (26/158) (χ(2)=42.001, P=0.000) for isolated peripheral lesions, respectively. In general, the consistency of these two methods was moderate in detecting fundus lesions (Kappa=0.630), HIV-related fundus lesions (Kappa=0.671), HIV-related microvascular retinopathy (Kappa=0.551), and isolated peripheral lesions (Kappa=0.450). According to the fundus location, the two methods showed high consistency in the detection of posterior/posterior involving lesions (Kappa=0.826>0.75) and perfect consistency for CMVR (Kappa=1.0).Conclusions:
The UWF retinal imaging system and the Superfield lens showed reasonable consistency in fundus screening in HIV/AIDS patients, especially for CMVR, or lesions in the posterior pole. (Chin J Ophthalmol, 2019, 55763-768).Palavras-chave
