RESUMO

PURPOSE: To describe the clinical characteristics, management, and outcomes of toddlers (under the age of 3) diagnosed with familial exudative vitreoretinopathy. METHODS: In this retrospective study, patients diagnosed with familial exudative vitreoretinopathy before the age of 3 were included. Presenting characteristics, genetic testing, management, and outcomes were collected. RESULTS: A total of 54 patients (108 eyes) with a mean age at diagnosis of 10.9 ± 2.6 months were included. Poor visual behavior (33%) and strabismus (26%) were the most common presenting symptoms, whereas screening only represented 11%. About half of included patients had a severe disease (stages 4 and 5). Genetic testing was positive in 40.7% of patients with 24% having a family history of familial exudative vitreoretinopathy. LRP5 was the most prevalent mutation (54.5%).Surgery was performed in 44.4% of eyes and was successful in 69.8% of cases. Failure exclusively occurred in eyes with severe stages. Among eyes evaluated for visual acuity (72 eyes), most (76.4%) had a vision of hand motion or better. CONCLUSION: Familial exudative vitreoretinopathy tended to be worse with earlier age at diagnosis, subsequently affecting the prognosis. Surgical intervention was common and primarily included lens-sparing vitrectomy and combined lensectomy and vitrectomy. Surgical success hinged on the stage of the disease.

RESUMO

AIM: To report on the distribution of eye diseases, aetiologies of severe visual impairment/blindness (SVI/BL) and unmet eye care needs of the Syrian refugee population and the Lebanese host community. METHODS: This retrospective study analysed the data of patients that were examined during the Ayounkon project -an eye health care project offering medical and surgical treatment for Syrian refugees and Lebanese host community in the Bekaa Valley in Lebanon. The project took place in three different primary health care centres and involved cooperation between several NGOs and ophthalmologists working on a voluntary basis. Data was analysed for distribution of eye diseases and aetiologies responsible for monocular and binocular SVI/BL. RESULTS: A total of 2067 patients were included, 677 were children < 18 years. The most frequent pathologies were ocular allergy (10%), and cataract (7.4%). 158 patients (7.6%) were referred for surgery. Glasses were prescribed for 1103 patients (53.4%), of whom 242 (21.9%) were children of school age. SVI/BL was found in 276 patients (13%). The condition was bilateral in 116 patients (42%). SVI/BL was significantly more frequent in the Syrian population than in the Lebanese (186 patients, 14.8% versus 86 patients, 11.3%; p = 0.04). The main causes for SVI/BL were cataract, keratoconus/corneal decompensation and amblyopia. CONCLUSION: The Syrian refugee population and the Lebanese host community have a high prevalence of ophthalmic pathologies and SVI/BL. Visual impairment is more prevalent in the refugee population. Our findings underscore the importance of targeted interventions and access to eye care services for these populations.

RESUMO

PURPOSE: To describe clinical features, management, and outcomes of posterior persistent fetal vasculature (PFV) and suggest a management algorithm. DESIGN: Retrospective, consecutive case series. PARTICIPANTS: All children diagnosed with posterior PFV and treated or followed at the Rothschild Foundation Hospital in France between June 2011 and September 2021. METHODS: Retrospective analysis of the clinical characteristics of posterior PFV. We reported age, gender, presenting symptoms, intraocular pressure, and visual acuity (VA) at diagnosis. Patients were divided into 4 groups depending on the severity and involvement or not of anterior segment. We reported the vitreoretinal surgical techniques used. MAIN OUTCOME MEASURES: Anatomic results, ocular hypertension, best-corrected distance visual acuity (BCDVA), presence of postoperative adverse events, and additional surgical interventions were recorded at each follow-up visit. RESULTS: Ninety-six patients were included. The median age at diagnosis was 8 months (IQR = 12), mean 18.9 ± 30.9 months) with a mean follow-up of 27 ± 31.2 months. Although PFV is often an isolated disease, it was associated with a systemic disease in 8% of cases. There was anterior involvement in 62 (64%) of eyes. Forty-one eyes (42.7%) were microphthalmic and more frequently associated with severe PFV (53% vs. 25%; P = 0.01). Surgery was performed in 85 patients (89%). Of them, 69 (81%) had a total success, 5 (6%) had a partial success due to persistent limited peripheral retinal detachment (RD), and 11 (13%) had a failure due to persistent total RD after surgery. Postoperative adverse events occured in 38 eyes including ocular hypertension requiring eye drop medication (7.1%), secondary cell proliferation around the intraocular lens (8.2%), intravitreal hemorrhages (7.1%), and persistent tractional RD (10.6%). Second surgery was performed in 18 patients (21%). At last follow-up, VA could be measured in logarithm of the minimum angle of resolution in 43 children (45%), light perception in 21 eyes (22%), and no light perception or impossible to assess in 32 eyes (33%). CONCLUSIONS: In our case series, most patients presenting with posterior PFV received complex vitreoretinal surgery. Goals of the surgery vary and include retinal flattening, reduction of vitreoretinal traction, freeing of visual axis, and aesthetic concerns. We propose a surgical and medical management algorithm for PFV. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

RESUMO

PURPOSE: To describe clinical characteristics and outcomes of children with early-onset X-linked retinoschisis. METHODS: In this retrospective consecutive case series, we included children diagnosed with symptomatic X-linked retinoschisis younger than 2 years. Presenting signs, clinical characteristics, treatments, and outcomes were recorded. RESULTS: Seven patients (14 eyes) with a mean age of 17.14 ± 6.28 months were included. Strabismus was the most common presenting symptom (6 of 7 patients, 86%). Clinical signs at the first diagnosis included peripheral retinoschisis in 13 eyes (13/14, 93%), of which 5 (5/13, 38%) were bullous, vitreous hemorrhage in 3 eyes (3/14, 21%), and retinal detachment in 3 eyes (3/14, 21%). The macula was involved in all eyes: It was detached in 2 eyes (2/14, 14%) and involved in the peripheral schisis in 4 eyes (4/14, 29%). In all remaining eyes, optical coherence tomography revealed foveoschisis. Six eyes (6/14, 42%) received surgery. At the last follow-up, visual acuity, when available, ranged from no light perception to 20/40, and no children had persistent retinal detachment. CONCLUSION: Children with early-onset X-linked retinoschisis had severe forms. All children had peripheral retinoschisis which was often bullous and extended to the macula. Diagnosis is often clinical but handheld optical coherence tomography can be helpful in atypical forms. Complications requiring surgical management are frequent.

RESUMO

PURPOSE: To evaluate the outcome for vitreoretinal surgery in children with familial exudative vitreoretinopathy (FEVR) and to evaluate the risk factors associated with failure. METHODS: This is a retrospective interventional case series of 43 consecutive eyes (34 patients) with vitreoretinal surgery for FEVR. Ocular status prior to intervention and at last follow-up and all surgical steps were recorded. Follow-up time was at least 6 months. Main outcome measure was surgical failure (defined as one of the following: (1) deterioration of visual acuity and stage, (2) persistence or development of total retinal detachment, (3) phthisis). RESULTS: After a mean follow-up of 3.3 ± 3.4 years (median 2.3; 0.5-15.7 years), surgery was successful in 30 eyes (70%) and failed in 13 eyes (30%). Twenty-one eyes (49%) improved, 13 (30%) remained stable, and 9 (21%) deteriorated. Postoperatively, stages and VA improved significantly (p = 0.001; p = 0.04, respectively). Surgical failure was only observed on patients with stages 4 and 5. Mean macular thickness decreased significantly in eyes (stages 2 and 3) with tractional epiretinal membrane. CONCLUSION: Eyes with tractional epiretinal membrane in stages 2 and 3 seem to benefit from vitrectomy and membrane peeling with a positive risk-benefit profile. Advanced stages have a low success rate and limited functional improvement, but in selected cases, surgery seems beneficial.

RESUMO

PURPOSE: To assess the anatomical and functional outcomes in addition to complications for endoillumination-assisted modified scleral buckling surgery using a noncontact Oculus BIOM wide-angle viewing system in patients with primary rhegmatogenous retinal detachment. METHODS: This is an interventional prospective noncomparative case series. Consecutive patients listed for scleral buckle surgery for primary rhegmatogenous retinal detachment were enrolled over an 18-month period and followed up for 1 year. The study cohort consisted of 25 patients (25 eyes) of which 23 patients (23 eyes) completed the 1-year follow-up. Scleral buckling surgery was done with a 23-gauge endoillumination probe, which was inserted through a pars plana sclerotomy. The primary outcome measure was anatomical success rate with one surgery assessed at the 6-month and the 1-year follow-up. Secondary outcome measures included final visual acuity, number of surgeries required, and complication rates such as entry site break, posterior vitreous detachment, endophthalmitis, and cataract. RESULTS: At 1 year, anatomical success with one surgery was achieved in 20 patients (87%). One patient required two additional vitreoretinal surgeries and 2 patients required three additional surgeries. All patients had a flat retina at 1 year with silicone oil present in one eye. Mean best-corrected visual acuity improved by six ETDRS lines, from 1.03 ± 0.83 logarithm of the minimum angle of resolution (20/200) preoperatively to 0.40 ± 0.47 logarithm of the minimum angle of resolution (20/50) at 1 year. No entry site breaks were detected, and posterior vitreous detachment developed in six patients (26%). No cases of endophthalmitis or cataract progression were reported. CONCLUSION: Endoillumination-assisted modified scleral buckling surgery combined with a noncontact wide-angle viewing system can provide good anatomical and functional outcomes with many advantages and a low complication rate.

RESUMO

PURPOSE: To evaluate the risk factors for elevated intraocular pressure (IOP) after pars plana vitrectomy (PPV) with silicone oil injection (SOI). PROCEDURES: This prospective interventional study included 254 consecutive eyes receiving PPV with SOI. RESULTS: Elevated IOP developed in 48% of the eyes postoperatively. The onset of IOP elevation was early (≤1 week) in 61.5% of the eyes, intermediate (1-6 weeks) in 28.7%, and late (> 6 weeks) in 9.8%. The incidence of IOP elevation was higher with primary uncomplicated rhegmatogenous retinal detachment than with tractional detachment (p = 0.01). Pseudophakia, high myopia, and high preoperative IOP were found to have higher incidences of ocular hypertension, whereas diabetic patients had a lower incidence. CONCLUSION: IOP elevation is a common complication following silicone oil (SO) tamponade. Risk factors for ocular hypertension development are pseudophakia, high myopia, high preoperative IOP, and low-viscosity SO.

RESUMO

PURPOSE: To describe the profile of patients with allergic conjunctivitis (AC) regarding their demographics, symptomatology and specific allergen sensitization, in a Lebanese tertiary hospital. METHODS: Cross-sectional study conducted at the Hôtel-Dieu de France hospital (Beirut, Lebanon) during a period of 18 months. Patients with seasonal or perennial AC presenting for ophthalmic consultation had measurements of total and specific IgE. A matching group of patients with AC seen at the allergist office during the same period underwent skin prick tests (SPTs). RESULTS: Forty-four patients were enrolled for blood work by their ophthalmologists. Seasonal and perennial forms were almost equivalent. In total, 56.8% had positive specific IgE, with higher prevalence in patients with seasonal AC (p = 0.002), other associated allergies particularly allergic rhinitis (p = 0.002) or a family history of allergy (p = 0.005). Ocular surface severity scales were not shown as predictors. High levels of total IgE were commonly detected in those with positive specific IgE. Thirty-eight patients were assessed with SPT, and all had a positive result for at least one allergen. Dust mites were found to be the most frequent allergens based upon both specific IgE (72%) and SPT (92%), followed by Parietaria and other pollens. CONCLUSION: In our study, dust mites mono- or co-sensitization is present in the majority of patients with AC, with odds of positivity being higher using SPT than specific IgE. The latter are found more readily in seasonal AC and in the presence of personal and family history of allergy.

RESUMO

BACKGROUND: Currently, there is no standardized approach for eyebrow shaping with botulinum toxin, and controversies still exist regarding this subject. OBJECTIVE: The objective of this systematic review is to summarize and compare all the published data regarding eyebrow shaping with botulinum toxin. METHODS: On March 10, 2017, an online search of published articles in the Medline, Embase, and Cochrane databases were conducted. All articles that used objective measurements to quantify the eyebrow changes after botulinum toxin injection were included in this review. RESULTS: Eleven studies were selected for inclusion with a total of 585 patients. All the included studies used onabotulinumtoxin A. Seven studies injected both the lateral and the medial eyebrow depressors, 2 studies injected the lateral depressors alone, and 2 studies injected the medial depressors alone. The highest elevation was observed in the lateral brow (0.4-4.8 mm). Bruising and headache were the most frequently reported complications, and only 5 cases of eyelid ptosis were noted. CONCLUSION: Botulinum toxin injection for eyebrow shaping is a noninvasive, safe, and reproducible procedure. Eyebrow reshaping can be achieved by targeting different muscle groups. However, further randomized controlled trials are warranted.

RESUMO

BACKGROUND: Chondrodermatitis nodularis helicis (CNH) is an idiopathic benign inflammatory painful condition of the ear. Still, to date, no study has yet evaluated nor compared treatments regarding their safety and efficacy. OBJECTIVE: The objective of this study is to review all available treatment modalities of CNH that were described in the literature, compare their efficacy and propose a treatment algorithm. METHODS AND MATERIALS: A systematic review of the literature was conducted using Embase, Medline, and Cochrane databases. Articles studying the management of CNH that reported data on the cure rates were included in this review. RESULTS: A total of 29 studies were included in the review. The 3 most commonly reported treatments for CNH are surgery, pressure relief, and topical nitroglycerin. Surgery has higher cure rate (82%) compared with pressure relief treatment (37%) or nitroglycerin (51%) (p < .0001). Surgery should be considered as the first-line treatment for CNH. Second-line treatments include nonsurgical therapies, particularly nitroglycerin and pressure relief techniques, alone or in combination. Third-line treatments include newer or less studied methods. CONCLUSION: Among the treatment modalities, surgery showed the highest cure rates. Adequately designed randomized controlled trials are warranted to compare newer therapeutic methods.

RESUMO

AIM: To determine the prevalence and the causes of severe visual impairment and blindness (SVI/BL) in children at a tertiary referral centre in Rwanda. METHODS: In this retrospective study, files of all patients <18 years presenting during the year 2019 at the Kabgayi Eye Unit in Rwanda with SVI/BL (presenting visual acuity of <6/60 Snellen or lack of preferential looking behaviour) in at least one eye were analysed for age, sex, laterality, province of origin and cause of SVI/BL. Causes were categorised according to WHO standard classification. RESULTS: Out of 3939 children presenting to the clinic, 428 (10.9%) had SVI/BL in at least one eye. 165 (4.2%) patients had bilateral and 263 (6.7%) had unilateral condition. Of patients with BL/SVI, 36.7% were below the age of 6 years. In bilateral BL/SVI, the main causes were cataract (18%), refractive error (18%), keratoconus (13%), congenital eye anomaly (9%), glaucoma (8%), cortical blindness (8%) and retinoblastoma (6%). In unilateral BL/SVI it was trauma (46%), cataract (8%), keratoconus (8%), infectious corneal disease (7%) and retinoblastoma (7%). In preschool children, retinopathy of prematurity accounted for 7% of bilateral BL/SVI. Avoidable BL/SVI accounted for 87% of all cases. CONCLUSION: The high number of avoidable causes for SVI/BL may be reduced through several cost-effective ways.

RESUMO

PURPOSE: To report on the anatomical and functional outcomes of a modified limbal lensectomy-vitrectomy (LV) approach for stages 4B and 5 retinopathy of prematurity (ROP) as defined in the International Classification of Retinopathy of Prematurity, 3rd Edition (ICROP 3). DESIGN: Retrospective, monocentric, consecutive case series. PATIENTS: Infants with ROP that underwent limbal LV for diffuse retrolental fibroplasia. METHODS: Clinical charts and Retcam photographs were reviewed. Surgical approach consisted of a limbal LV through peripheral iridectomies with centripetal dissection of the preretinal fibrosis. MAIN OUTCOME MEASURES: Anatomical success and visual function at last follow-up were evaluated. Multivariate logistic regression was used to explore potential prognostic factors affecting the anatomical outcome. RESULTS: A total of 128 eyes of 81 patients with a mean gestational age of 28.7 ± 3.0 weeks and a mean birthweight of 1244 ± 429 g were included. Eighteen eyes (14.1%) had a stage 4B, 24 (18.8%) a stage 5B, and 86 a stage 5C (67.2%) ROP. Mean age at surgery was 57.4 ± 36.3 weeks and mean postoperative follow-up was 22.7 ± 20.4 months. Only 5 eyes (3.9%) had prior peripheral retinal ablation. Macular reattachment was achieved in 74 eyes (57.8%). Controlling for other baseline factors, a stage 5C (versus stage 4B, odds ratio [OR] = 6.9 [1.5-32.1], P = 0.01 and versus stage 5B, OR = 7.4 [1.5-37.1], P = 0.02), the presence of vascular activity (OR = 6.4 [2.3-18.1], P < 0.001), and the presence of Schlieren sign (OR = 13.0 [2.1-82.2], P = 0.006) were associated with a failure of macular reattachment. Visual acuity was assessed in 92 eyes (71.9%), among which 59 eyes (64.1%) had light perception or better. CONCLUSIONS: Modified limbal LV resulted in macular reattachment in more than half of eyes with ROP-related retinal detachment and diffuse retrolental fibrosis. A stage 5C based on ICROP 3, the presence of vascular activity, and a Schlieren sign were significantly associated with a failure of macular reattachment.

RESUMO

PURPOSE: To the describe OCT imaging characteristics of a cohort of patients showing spontaneously closing degenerative or mixed type lamellar macular holes (LMH) and to compare them to the ones of a sex and age matched group showing stable lesions. METHODS: Patients diagnosed with degenerative and mixed type LMHs showing OCT-documented spontaneous anatomical closure were retrospectively selected from 3 specialized retina centres. An equal number of age and sex matching subjects were randomly selected among patients with anatomically stable lesions. RESULTS: Eleven (11) spontaneously closing (SC group) and 11 stable (ST group) degenerative LMH with a mean follow up of 4 years were recruited. Hyperreflective inner border (HIB) and linear hyperreflectivity in the outer plexiform layer (LHOP) at baseline were significantly more prevalent in SC group in processed images (respectively p = 0.007 and p = 0.003). A borderline significance in lamellar hole associated epiretinal proliferation (LHEP) at last follow up was detected (p = 0.085). As for mixed type LMH, 10 patients for SC group and 10 for ST group were recruited. LHOP at baseline in processed images was significantly more prevalent in SC group (p = 0.005). CONCLUSIONS: Spontaneously closing LMHs show higher prevalence of HIB and LHOP at the beginning of the closing process, a difference which is enhanced by image processing. These signs might be a signal of microglial and Muller cells coordinated activation.

RESUMO

PURPOSE: To elaborate a deep learning (DL) model for automatic prediction of late recurrence (LR) of rhegmatogenous retinal detachment (RRD) using pseudocolor and fundus autofluorescence (AF) ultra-wide field (UWF) images obtained preoperatively and postoperatively. MATERIALS AND METHODS: We retrospectively included patients >18 years who underwent either scleral buckling (SB) or pars plana vitrectomy (PPV) for primary or recurrent RRD with a post-operative follow-up >2 years. Records of RRD recurrence between 6 weeks and 2 years after surgery served as a ground truth for the training of the deep learning (DL) models. Four separate DL models were trained to predict LR within the 2 postoperative years (binary outputs) using, respectively, UWF preoperative and postoperative pseudocolor images and UWF preoperative and postoperative AF images. RESULTS: A total of 412 eyes were included in the study (332 eyes treated with PPV and 80 eyes with SB). The mean follow-up was 4.0 ± 2.1 years. The DL models based on preoperative and postoperative pseudocolor UWF imaging predicted recurrence with 85.6% (sensitivity 86.7%, specificity 85.4%) and 90.2% accuracy (sensitivity 87.0%, specificity 90.8%) in PPV-treated eyes, and 87.0% (sensitivity 86.7%, specificity 87.0%) and 91.1% (sensitivity 88.2%, specificity 91.9%) in SB-treated eyes, respectively. The DL models using preoperative and postoperative AF-UWF imaging predicted recurrence with 87.6% (sensitivity 84.0% and specificity 88.3%) and 91.0% (sensitivity 88.9%, specificity 91.5%) accuracy in PPV eyes, and 86.5% (sensitivity 87.5%; specificity 86.2%) and 90.6% (sensitivity 90.0%, specificity 90.7%) in SB eyes, respectively. Among the risk factors detected with visualisation methods, potential novel ones were extensive laser retinopexy and asymmetric staphyloma. CONCLUSIONS: DL can accurately predict the LR of RRD based on UWF images (especially postoperative ones), which can help refine follow-up strategies. Saliency maps might provide further insight into the dynamics of RRD recurrence.

RESUMO

PURPOSE: To describe a new surgical technique and outcomes of lens-sparing vitrectomy and retrolental stalk dissection in posterior persistent fetal vasculature (PFV). DESIGN: Retrospective interventional case series. METHODS: RESULTS: Among the 21 included eyes, 8 (38%) had no macular involvement and 4 (19%) presented with microphthalmia. Median age at the first surgery was 8 months (range: 1-113 months). Surgical success was obtained in 71.4% of cases (15 of 21). In the remaining cases, the lens was removed because of capsular rupture in 2 cases (9.5%) and a large capsular opacity after stalk removal or an adherent stalk impossible to dissect in 4 cases (19.1%). In the capsular bag, IOL implantation was accomplished for all but 1 eye. None of the eyes developed retinal detachment or required glaucoma surgery. Endophthalmitis occurred in 1 eye. Secondary lens aspiration was needed in 3 eyes after a mean interval of 10.7 months following initial surgery. At last follow-up, half of the eyes remained phakic. CONCLUSION: Lens-sparing vitrectomy is a useful approach to addressing the retrolental stalk in selected cases of persistent fetal vasculature syndrome. By delaying or avoiding lens extraction, this approach allows preservation of accommodation, reduction of the risk of aphakia, glaucoma, and development of secondary lens reproliferation.

RESUMO

PURPOSE: To report on the outcome of surgical submacular choroidal neovascular membrane (CNV) removal in children and to perform a comprehensive review of literature concerning this intervention in children. METHODS: In this retrospective, noncomparative, interventional case series, we included 8 eyes of 7 consecutive children with subfoveal choroidal neovascularization treated by pars plana vitrectomy (PPV) and CNV removal. Main outcome measures were visual acuity and complications. RESULTS: Mean age at surgery was 8.6 ± 5.2 years (range: 2-16). Two out of 8 eyes were idiopathic. Corrected-distance visual acuity (CDVA) improved from 1.01 ± 0.45logMAR (range:0.3-1.5) at presentation to 0.60 ± 0.37 (range:0-1) at last follow-up (p = 0.03). Mean follow-up was 3.9 ± 3.9 years. Six eyes received at least one intravitreal injection of bevacizumab prior to surgery. Recurrence occurred in one eye with Best's disease.Literature review revealed a total of 42 cases with the most frequent etiologies being Presumed ocular histoplasmosis syndrome (POHS) and idiopathic CNV. Considering all cases together, mean CDVA improved from 1.00 ± 0.37logMAR to 0.52 ± 0.42 (p < 0.01). CNV recurrence occurred in 11 eyes (22.0%), 7 of which had an inflammatory etiology. Other complications included pigment epithelium tear, atrophy and retinal tear. CONCLUSION: Surgical removal of CNV is a viable, effective and safe option in children with persistent submacular neovascular membranes.

RESUMO

Purpose: To compare clinical characteristics at presentation and outcomes of Coats disease between females and males. Methods: In this retrospective, consecutive case series we included all children diagnosed with Coats disease in a single tertiary referral center. Initial clinical presentation, treatment and outcomes were collected. Results: A total of 158 children were included, of whom 29 (18.3%) were females and 11 (6.9%) had bilateral involvement. Age at diagnosis and disease stage were similar between females and males. Females had more bilateral involvement (p < 0.001) and tended to have a worse visual acuity at diagnosis (p = 0.05). At last follow-up, visual acuity and anatomical outcome after treatment were similar between genders. Conclusion: Female patients with Coats disease had more bilateral involvement and tended to have worse visual acuity at presentation. Clinical presentation and outcomes seemed to be similar between genders.

RESUMO

PURPOSE: To evaluate the current French screening guidelines for retinopathy of prematurity (ROP) and to suggest modifications to it. METHODS: In this multicentric retrospective, noncomparative, interventional case series we included infants with a gestational age (GA) ≤32 weeks who were screened for ROP by fundus examination between 2011 and 2018. Main Outcome Measures were the presence of ROP and the need for treatment. RESULTS: A total of 2246 children with a mean GA of 28.9 ± 2.0 weeks and mean birth weight (BW) of 1141.1 ± 332.0 g were screened. Retinopathy of prematurity (ROP) was found in 683 infants (30.4%), of whom 145 (6.5%) had type 2 ROP and 58 (2.6%) had type 1 ROP. Mean GA of infants with type 1 ROP needing treatment was 25.9 + 1.5 weeks (range: 23.6-30) and mean BW was 774.1 ± 173.7 g (range: 540-1400). Both GA and BW had an impact on the development of type 1 and 2 ROP. None of the infants needing treatment had a GA of 31 weeks or more. None of the children needed treatment before 33 weeks of postmenstrual age (PMA) or 6 weeks of postnatal age (PNA). CONCLUSION: It seems possible to decrease the screening of premature infants to ≤31 weeks of GA and to start screening at 31 weeks PMA for infants having a GA < 26 weeks and at 6 weeks PNA for more mature children.

RESUMO

We report the 51/2 year prevalence of visual and oculomotor impairments in preterm children born at 24−34 weeks' gestation (WG) using the population-based cohort study EPIPAGE-2, set in France, 2011. The main outcomes were imputed prevalence of refractive errors (REs), strabismus, and binocular visual acuity (VA). Children were clinically assessed by specially trained pediatricians. The population was also analyzed in terms of cerebral palsy at 51/2 years (no CP, stage 1, stage 2, or stage 3−5) and retinopathy of prematurity in the neonatal period (no ROP, stage 1 or 2, or severe ROP). Among the 4441 children included, 2718 (weighted percentage 58.7%) were clinically assessed. REs were reported in 43.1% (95% confidence interval 37.6−48.4), 35.2% (32.7−37.6), and 28.4% (25.0−31.8) of children born at 24−26, 27−31, and 32−34 WG (p < 0.01), respectively; strabismus rates were 19.5% (14.6−24.4), 14.8% (12.9−16.7), and 8.3% (6.2−10.4) (p < 0.001), respectively. Moderate/severe visual deficiencies (VA < 3.2/10) were present in 1.7% (0.2−3.3) of children born at 24−26 WG, and in less than 1% in other groups. A suboptimal VA 5/10−6.3/10 was measured in 40.6% (35.3−45.8) of children born at 24−26 WG, 35.8% (33.5−38.1) at 27−31 WG, and 33.7% (30.4−37.0) at 32−34 WG. CP and ROP were associated with strabismus and RE. The association between CP and VA was strong, while it was not observed for ROP. In this large cohort of preterm-born children, we found a high prevalence of RE and strabismus regardless of WG, supporting the need for specific attention in this population. High prevalence of suboptimal VA could be challenging for these children at the age of reading and writing acquisition.
