ABSTRACT

Congenital entropion, an abnormal condition in which the eyelids roll inward, with the eyelashes losing their normal angulation and tilting toward the eye, especially in the lower eyelids and inner canthus, often occurs in infants and young children. Congenital entropion may lead to corneal epithelial abrasion, inflammation and ulcer, which may affect the function of the eye if not treated in time. Early surgical intervention is helpful to the health of children's eyes. The purpose of surgery is to change the structure of eyelid and weaken the force of entropion, thus improving the symptoms and corneal astigmatism. At present, there are many surgical treatments for congenital entropion. In this paper, the advantages, disadvantages and indications of these treatments are analyzed and summarized, providing a reference for clinical practice.

ABSTRACT

Objective To observe the morphologic alterations of retina pigment epithelial around fluorescein leakage site using spectral-domain optical coherence tomography (SD-OCT) in acute central serous chorioretinopathy (CSC) before and after laser coagulation.Methods Twenty-four eyes of 24 consecutive patients with unilateral acute CSC who underwent laser photocoagulation (wave length:561 nm,energy:80-100 mW,spot diamteter:100 μm,exposure time:0.1 s) were enrolled in this retrospective study.The patients included 22 males and 2 females,with an average age of (39.2± 7.2) years and an average duration of (1.1 ± 0.6) months.The fluorescein leakage outside the foveal avascular zone and serous retinal detachment were found in all the eyes by fluorescein fundus angiography (FFA) and SD-OCT.Twenty-six leakage sites were observed in 24 eyes on FFA.There were 5 smoky leakage points (19.2%),21 inky leakage points (80.8 %).The retinal pigment epithelial (RPE) layer at leakage points were scanned by SD-OCT before and at 2 weeks,2 months after treatment.SD-OCT showed that the RPE abnormalities were detected at all of the fluorescein leakage points,including serous pigment epithelial detachment (PED) in 16 leakage points (64.5%),protruding RPE in 5 leakage points (19.5%),and irregular RPE in 5 leakage points (19.2%).The morphologic alterations of RPE around fluorescein leakage point before and after laser coagulation were observed.Results At 2 weeks after laser photocoagulation,PED existed in 7 leakage points (26.9%),protruding RPE in 3 leakage points (11.5%),and irregular RPE in 16 leakage points (61.5%).At 2 months after laser photocoagulation,protruding RPE existed in 3 leakage points (11.5%),and irregular RPE in 5 leakage points (19.2%),including RPE defect in 2 leakage points.And there were undetectable RPE abnormalities in other 16 leakage points (61.5%).Conclusions In acute CSC,SD-OCT shows that morphologic features of the RPE layer are changed,including PED,protruding RPE,irregular RPE around the leakage point.After laser photocoagulation the abnormalities of RPE can also be altered from PED to irregular RPE,and RPE defect is observed in restricted regions.
