Wide-field, illumination-agile, oximetric retinal imaging with a handheld camera

Abstract Purpose This study aimed to determine the proportion and types of ocular abnormalities detected in healthy term newborns and also the risk factors associated with retinal haemorrhages. Method This cross-sectional study comprised of 203 participants, all healthy term newborn infants in the Obstetrics and Gynaecology ward at Hospital Kuala Lumpur over a six months period. The examination list includes external eye examination, red reflex test, and fundus imaging using a wide-field digital retinal imaging system (Phoenix Clinical ICON Paediatric Retinal Camera) by a trained Investigator. The pathologies detected were documented. The results were compared with similar studies previously published in the literature. Results Total ocular abnormalities were detected in 34% infants. The most common finding was retinal haemorrhage in 29.6% infants, of which 53.3% occurred bilaterally. Spontaneous vaginal delivery (SVD) remained the greatest risk factor which has nearly four times higher risk of newborns developing retinal haemorrhage compared to Lower Segment Caesarean Section (LSCS). There was a 6% increased likelihood of developing retinal haemorrhage for every 1 minute increment in the duration of 2nd stage of labour. Newborns delivered via SVD with episiotomy had 2.5 higher odds of developing retinal haemorrhage in newborns compared to SVD without episiotomy. Conclusion Universal eye screening for all newborns using a wide-field digital imaging system is possible, safe and useful in detecting posterior segment disorders. The most common abnormality detected is retinal haemorrhage. Although most resolve spontaneously, a longitudinal study is needed to study the long term effect of retinal haemorrhages in these infants.

Abstract Background: To observe the retinal lesions in HIV/AIDS patients and to evaluate the consistency of non-mydriatic ultra-wide-field (UWF) retinal imaging and mydriatic slit lamp biomicroscope with Superfield lens. Methods: 193 eyes of 98 consecutive HIV/AIDS patients were enrolled. The retinal lesions in each patients were observed through UWF fundus imaging and slit lamp biomicroscopic with Superfield lens whose consistency was analyzed. Results: 100 eyes (51.8%） had fundus lesions, 20 eyes (20%) presented posterior microvascular retinopathy (MVR), 19 eyes (19%) presented peripheral MVR, 15 eyes (15%) presented early stage cytomegalovirus retinitis (CMVR), 6 eyes showed initial stage CMVR, and 51 eyes showed other changes (papilledema, etc.). The consistency of two methods was moderate in detecting the isolated peripheral lesions (Kappa = 0.445) or HIV-related MVR (Kappa = 0.513), and high in inspecting the posterior/posterior involved lesions (Kappa = 0.831) or CMVR (Kappa = 1.0). The detection rate of UWF retinal imaging and slit lamp biomicroscopic were 15.5%（30/193）and 17.6%（34/193）(P=0.557＞0.05) for HIV-related MVR, 7.8% (15/193) (P=1.000＞0.05) for CMVR, 37.3% (72/193) and 33.7% (65/193) (P=0.118＞0.05) for posterior/posterior involved lesions, 8.8% (17/193) and 17.6% (34/193) (P=0.001＜0.05) for isolated peripheral lesions , respectively. Conclusions: The HIV-related MVR can be posterior or peripheral. Various fundus changes appear in HIV/AIDS patients, not only MVR or CMVR. The non-mydriatic UWF fundus imaging system and mydriatic slit lamp biomicroscope exhibited good consistency and nondiscriminatory detection rate for CMVR, HIV-related MVR and posterior lesions, but not for isolated peripheral lesions.
