Purpose: To investigate predictive factors for retreatment after intravitreal ranibizumab injection as first-line treatment for retinopathy of prematurity (ROP).Methods: The medical records of consecutive infants diagnosed with type 1 ROP from 2013 to 2021 who received 0.2 mg intravitreal ranibizumab as their first treatments were retrospectively reviewed. 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.

Purpose: To evaluate the long-term results of Boston type-I keratoprosthesis implantation in Korea.Methods: Medical records of six patients (six eyes) who underwent Boston type-I keratoprosthesis implantation between August 2018 and November 2019 were retrospectively reviewed for more than 36 months.Results: The mean follow-up period was 44.3 ± 7.0 months. Best corrected visual acuity (BCVA) improved significantly for all six eyes, from 2.33 ± 0.51 logarithm of the minimum angle of resolution (logMAR) to 0.67 ± 0.59 logMAR. The vision recovered immediately after the surgery in all patients. Retroprosthetic membrane developed in three of the patients, but the visual acuity remained unchanged. Anatomical success was achieved in all six eyes after Boston type-I keratoprosthesis implantation.Conclusions: The long-term analysis of Boston type-I keratoprosthesis implantation showed a faster recovery and improved visual acuity compared with conventional penetrating keratoplasty. Without the use of systemic immunosuppressants, all six eyes showed long-term survival of the Boston keratoprosthesis. Boston type-I keratoprosthesis implantation may be used in patients with recurrent graft failure after keratoplasty. This was the first study investigating the long-term results of Boston keratoprosthesis implantation in Korean patients.

Purpose: To evaluate the clinical outcomes of a new refractive corneal lenticule extraction method (SmartSight) using a Schwind ATOS femtosecond laser (Schwind Eye-Tech-Solutions, Kleinostheim, Germany).Methods: The medical records of 338 eyes of 170 patients who underwent SmartSight treatment from April to September 2022 and were followed-up for at least 3 months were retrospectively analyzed. The patients were followed-up at 1 day, 1 week, and 1 and 3 months after operation. Refraction, visual acuity, and intraocular pressure were measured at each visit.Results: Preoperatively, the uncorrected distant visual acuity was 1.26 ± 0.33 logarithm of minimum angle or resolution (logMAR) and the spherical equivalent was -4.52 ± 1.77 diopters. The 3-month, postoperative, uncorrected distant visual acuity was 0.01 ± 0.03 logMAR and the spherical equivalent was -0.12 ± 0.22 diopters. The 3-month data were as follows: efficacy of refractive surgery, 0.99 ± 0.11; safety, 1.00 ± 0.05; predictabilities at ±0.5 and ± 1.0 diopters, 97% and 100%, respectively.Conclusions: Myopic astigmatism correction using the SmartSight method was effective, safe, and predictable in terms of visual outcomes.

Purpose: To investigate the effects of humidity, temperature, and fine particulate matter (PM2.5) on dry eye disease (DED) parameters in primary Sjogren's syndrome patients.Methods: We retrospectively analyzed the medical records of 18 primary Sjogren's syndrome patients who underwent DED treatment and had more than two follow-up visits. 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). The high humidity, high temperature, and low PM2.5 groups had lower SANDE scores (p = 0.017, = 0.063, and = 0.049, respectively) and tear osmolarity (p < 0.001, = 0.009, and < 0.001, respectively). Multiple regression analysis showed that temperature and humidity had stronger correlations with tear osmolarity (p = 0.005 and = 0.012, respectively) compared to PM2.5 concentrations.Conclusions: Ocular discomfort and tear osmolarity were correlated with temperature, humidity, and PM2.5 concentrations. Among the DED parameters, tear osmolarity was the most sensitive indicator of exposure to environmental factors.

Purpose: We report a patient diagnosed with COVID-19-associated hypertensive anterior uveitis and endotheliitis of the cornea.Case Summary: A 71-year-old male visited our hospital with decreased visual acuity, ocular pain, eyelid swelling of in his right eye, and headache for 8 days. 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.

Purpose: To report an iris metastasis associated with non-small-cell lung cancer (NLC) confirmed via repeat aqueous humor cytology.Case summary: A 53-year-old female presented to our ophthalmology outpatient department with complaints of vision impairment and pain in the left eye 1 month in duration. In ophthalmologic examinations, the best-corrected visual acuities were 20/20 oculus dexter (OD) and 20/32 oculus sinister (OS). The intraocular pressures measured using standard Goldmann applanation tonometery were 12 mmHg OD and 42 mmHg OS. Slit-lamp examination revealed multiple iris nodules in the left eye. 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. One week later, aqueous humor sampling was repeated. Malignant cells were histopathologically confirmed. Given the ocular metastasis, the oncologists changed the chemotherapy regimen.Conclusions: When an NLC patient exhibits iris nodules, repeat aqueous humor cytology can confirm an iris metastasis.

Purpose: To obtain an overview of the surgical practices for the management of intermittent exotropia among experienced surgeons.Methods: We conducted a survey of members of the Korean Association for Pediatric Ophthalmology and Strabismus, who had experience of > 15 years in strabismus surgery, via e-mail. Surgical methods for basic-type intermittent exotropia, angle of deviation for determining the surgical dose, reasons for surgical dose adjustment, and the postoperative target angle of deviation were analyzed.Results: Bilateral lateral rectus recession was preferred over unilateral recession and resection for basic-type intermittent exotropia with or without a dominant eye. The preoperative maximum angle of deviation was preferred for determining the surgical dose by 56% of the participants. Two-thirds of the participants preferred to reduce the surgical dose in specific circumstances, lateral incomitancy being the most common reason. In case of true divergence excess-type intermittent exotropia, 47.7% of the participants reduced the surgical dose. The most preferred target angle of deviation at 1 day postoperatively was 11-15 prism diopter esodeviation, as reported by 40% of the participants.Conclusions: Although experienced surgeons had different surgical preferences for intermittent exotropia, a general trend was found. This survey may be a useful reference for beginners in strabismus surgery.

Purpose: To compare the refractive outcomes of closed C-loop and C-loop intraocular lenses (IOLs) following phacovitrectomy with gas tamponade.Methods: Medical records of 42 patients (43 eyes) who underwent phacovitrectomy with gas tamponade for idiopathic macular holes between January 2021 and June 2022 were retrospectively reviewed. Closed C-loop (26 eyes; Eyelike K-flex Aspheric®, Koryo Eyetech, Seoul, Korea) and C-loop (17 eyes; Tecnis® ZCB00, Johnson & Johnson Vision, Santa Ana, CA, USA) IOLs were surgically implanted. The main outcome measures were postoperative prediction error and absolute error.Results: There was no significant difference in mean absolute error at 5 months postoperatively (0.34 ± 0.24 diopters [D] and 0.30 ± 0.25 D in the closed C-loop and C-loop IOL groups, respectively; p = 0.502). The mean prediction error at 5 months postoperatively also showed no significant difference between the groups (-0.28 ± 0.30 D and -0.16 ± 0.36 D, respectively; p = 0.242). Myopic shift was observed in both groups.Conclusions: There was no significant difference in refractive outcomes between closed C-loop IOLs and C-loop IOLs. A myopic shift was observed in both groups; this should be taken into consideration when calculating IOL power following phacovitrectomy with gas tamponade.

Myopic shift was observed in both groups.Conclusions: There was no significant difference in refractive outcomes between closed C-loop IOLs and C-loop IOLs. A myopic shift was observed in both groups; this should be taken into consideration when calculating IOL power following phacovitrectomy with gas tamponade.","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":"45943862","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}

Purpose: To identify the clinical outcomes of cataract surgery in patients with advanced glaucoma.Methods: A retrospective chart review of open-angle glaucoma patients who underwent cataract surgery and were followed-up for 1 year was conducted. 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). The mean IOP difference between the two groups was not significant at months 1, 3, 6, 12, or 24 postoperatively (all p > 0.05). Both groups evidenced VA improvements at 1 year postoperatively and the visual field (VF) indices did not differ from those before surgery. The numbers of antiglaucoma medications used decreased after surgery, but the decrease was significant only in the advanced glaucoma group (p = 0.030).Conclusions: The advanced and mild-to-moderate glaucoma groups evidenced similar IOP and VF changes after cataract surgery. The VA improved and the number of antiglaucoma medications decreased. Our findings suggest that cataract surgery for patients with advanced glaucoma may afford similar clinical outcomes compared to other less severe glaucoma groups.

Purpose: This study introduces a new machine learning-based auto-merge program (HydraVersion) that automatically combines multiple ocular photographs into single nine-directional ocular photographs. We compared the accuracy and time required to generate ocular photographs between HydraVersion and PowerPoint.Methods: This was a retrospective study of 2,524 sets of 250 nine-directional ocular photographs (134 patients) between March 2016 and June 2022. The test dataset comprised 74 sets of 728 photographs (38 patients). We measured the time taken to generate nine-directional ocular photographs using HydraVersion and PowerPoint, and compared their accuracy.Results: HydraVersion correctly combined 71 (95.95%) of the 74 sets of nine-directional ocular photographs. The average working time for HydraVersion and PowerPoint was 2.40 ± 0.43 and 255.9 ± 26.7 seconds, respectively; HydraVersion was significantly faster than PowerPoint (p < 0.001).Conclusions: Strabismus and neuro-ophthalmology centers are often unable to combine and store photographs, except those of clinically significant cases, because of a lack of time and manpower. This study demonstrated that HydraVersion may facilitate treatment and research because it can quickly and conveniently generate nine-directional ocular photographs.
