Patients underwent LASEK in one eye, and T-PRK in the other. The degree of pain was rated on a scale of 0-10 on postoperative days 1, 2 and 3. Uncorrected visual acuity (UCVA) and subepithelial corneal haze were assessed at postoperative 1 and 3 months.Results: The pain was relieved on the 4th postoperative day in all patients, healing of corneal epithelium was observed at 4-5 days after surgery and contact lenses were removed promptly. At postoperative 1 day, the mean subjective pain score in the LASEK group was 3.2 ± 1.88 and 4.43 ± 1.61 in T-PRK group (P = 0.008). No significant difference was found between two groups on postoperative 2 and 3 days. At postoperative 3 months, the percentage of UCVA ≥ 0.8 in the LASEK group was 100% and 96.7% in the T-PRK group (P = 0.24), 93.3% of patients in the LASEK with UCVA ≥ 1.0 and 90% in the T-PRK group (P = 0.64). In the LASEK group, the value of corneal haze was 0.26 ± 0.21 and 0.27 ± 0.25 in the T-PRK group (P = 0.877).Conclusion: Good visual acuity was obtained in both groups at postoperative 3 months. Compared with those in the T-PRK group, patients undergoing had less discomfort in the LASEK group, which may be associated with corneal epithelial activity. The changing curve of subjective pain in the T-PRK group was relatively flat and stable at postoperative 3 days.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":"29 3","pages":"155-9"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33335282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A database with 367 subjects under 14 years of age (598, including second-round surgeries) was generated.Results: Of this cohort (n = 367; males: 232, 63.2%; females: 135, 36.8%), 200 patients (54.5%) had bilateral cataracts, and 258 (70.3%) were under 3 years of age. In all age groups and in all subtypes of pediatric cataract, males were most commonly affected. Congenital cataract was the most prevalent subtype, accounting for 296 patients (80.7%). Most congenital cataracts were associated with other ocular or systemic abnormalities; and in 48 patients (16.22%), they were hereditary. Traumatic cataract was the most common subtype (85.92%) of acquired cataract. The few instances of cataracts due to steroids (n = 3) or to metabolic disorders (n = 2) occurred in males and involved both eyes.Conclusion: The majority of pediatric cataracts in this patient population were congenital in nature. A significant lag in ophthalmologic evaluation of Chinese infants was evident and should be addressed by educating both children and parents on risk factors for cataract development. Regular assessments are especially important in children subjected to long-term systemic steroid treatments.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":"29 3","pages":"138-42"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33335279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anterior segment and vitreous body examinations were unremarkable. Yellowish spots in the macular area were observed. Spectral domain optical coherence tomography (SD-OCT) imaging of the macula showed loss of the inner segment/outer segment (IS/OS) photoreceptor junction, with irregularity of the retinal pigment epithelium (RPE), and a V-shaped hernia of the retina into the choroid. The macular lesions emerged as mild window defects on fluorescein angiography and were visualized as hypofluorescent patches on all-phase indocyanine green angiography.

Here, we describe two cases of war and outdoor activity open globe eye injury where, despite a low OTS score, current microsurgical technology allowed for a favorable outcome.Case report 1: A 33-year-old Libyan soldier had been treated for an open-globe grenade blast trauma to his left eye, which showed light perception and OTS score 2. He had undergone a lensectomy and PPV with silicone oil tamponade. Surgical treatment included scleral buckling, cornea trephination, temporary Eckardt keratoprosthesis, PPV revision, intraocular lens (IOL) implantation, and corneal grafting. Six months later, his VA was improved to 20/70. CASE REPORT 2: A 35-year-old man presented with a corneal laceration in his left eye from a meat skewer, with marked hypotony and LP. After primary corneal wound closure, B-scan ultrasonography revealed massive vitreous hemorrhage (OTS score 2). The patient underwent open cataract extraction with IOL implantation, 23 gauge PPV, laser photocoagulation of the retinochoroidal laceration, and a gas tamponade. After three weeks, the patient underwent a 2nd 23G PPV due to a fibrinous reaction.
