Only eyes with severe ROP were included. Retreatment was performed if eyes again met the criteria for type 1 ROP or presented with stage 3 ROP and the plus sign. Factors around the time of first injection that predicted retreatment were assessed.Results: Intravitreal ranibizumab was injected into 44 eyes of 44 infants. The mean gestational age (GA) and body weight were 27.8 weeks and 1,046.6 g, respectively. Retreatment was required by 21 eyes (47.7%) at an average of 8.9 weeks after the first injection, thus at 37.2 weeks of mean postmenstrual age. The retreatment group exhibited a lower GA (p = 0.036), lower 1 minute (min) (p = 0.014) and 5 min (p = 0.029) Apgar scores, and more quadrants with plus signs (p = 0.044) before the first injections; they also had a longer period of oxygen requirement (p = 0.001), more loss of the plus sign (p = 0.014), and more ROP involution (p = 0.003) after the first injections. The risk of needing retreatment increased with a lower 1 min Apgar score (p = 0.010, odds ratio [OR] = 2.04) and later disappearance of the plus sign (p = 0.013, OR = 1.44) after the first injection.Conclusions: About half of patients with type 1 ROP may require retreatment 2 months after the first ranibizumab injection. Delayed loss of the plus sign increases the risk of retreatment; careful fundus examination is recommended after the first injection.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135355091","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}

Symptom Assessment in Dry Eye (SANDE) scores, tear secretion, tear film breakup times, ocular surface staining scores, and tear osmolarity were assessed. Temperature, humidity, and PM2.5 concentrations during the week before the patient visits were calculated using public data and their relationships with DED parameters were analyzed.Results: All patients were females, with an average age of 57.6 ± 12.4 years. High temperature was significantly correlated with humidity and PM2.5 concentration (p = 0.004 and = 0.006, respectively).

He had been diagnosed with COVID-19 pneumonia 10 days before the visit. The best-corrected visual acuity was 0.04 in his right eye and 0.15 in his left eye. Severe conjunctival injection, moderate corneal edema with Descemet membrane folding, diffuse keratic precipitates and mild anterior chamber reaction were observed in the right eye, which were not present in the previous examination. Pupils in both eyes were moderately dilated and slow to react in response to direct light. The density of endothelial cells in the right eye was 711 cells/mm2 and an owl’s eye morphology of endothelial cells was observed via specular microscopy. During follow up, elevated intraocular pressure (IOP) in the right eye was noted. Polymerase chain reaction (PCR) examination of the aqueous humor for cytomegalovirus was negative. After 2 weeks of applying prednisolone eye drops and anti-glaucoma eye drops, corneal edema decreased, and his vision improved to 0.5. However, the density of the corneal endothelium remained low.Conclusions: Although there have been worldwide case reports of conjunctivitis, keratitis, or uveitis after COVID-19 infection, this study presents the first reported case of COVID-19 associated hypertensive anterior uveitis and endotheliitis of the cornea.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48250037","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}

Thirteen months prior, the patient had been diagnosed with NLC and was on chemotherapy. Despite the maximal tolerated medical therapy, the intraocular pressure was not controlled. As an iris metastasis was suspected, anterior chamber paracentesis was performed for aqueous humor sampling. Cytological analysis did not reveal malignant cells.

Advanced glaucoma was defined as a mean deviation (MD) < -12 dB on the preoperative visual field test. A group with mild-to-moderate glaucoma (MD ≥ -12 dB) served as the control group. Changes in intraocular pressure (IOP) at 1, 3, 6, and 12 months, and in the postoperative visual acuity (VA) as well as in the visual field indices (MD and the pattern standard deviation), and the number of antiglaucoma medications were compared.Results: Eighty-seven eyes (87 patients) of the advanced group and 109 eyes (109 patients) of the mild-to-moderate group were finally included. From 1 week to 24 months postoperatively, both groups evidenced IOP decreases compared to the preoperative values (both p < 0.05). The IOP spike prevalence was similar in the two groups (11% vs. 13%, p = 0.199).
