Pediatric and Adolescent Traumatic Macular Hole: A Systematic Review.

PURPOSE: The optimal management of pediatric traumatic macular holes (TMH) is unclear from lack of prospective randomized trials. The literature is divided into early (≤1month post-trauma), delayed (>1month) pars plana vitrectomy (PPV), and observation. Our aim is to find which group can achieve superior spectacle corrected visual acuity (VA), visual gain, and time for hole closure. DESIGN: Systematic Review. METHODS: This systematic review was registered with PROSPERO (ID:CRD42022383134). The databases searched from inception until July 31, 2023, were MEDLINE OVID, Scopus, Web of Science, and Embase and Google Scholar. The articles were screened for title and abstract then for full text. Risk of bias was also assessed. Three outcome measures were analyzed: final VA, visual gain, and time to closure of MH. MH size was divided into small (≤250 µm), medium (>250-500 µm), and large (>500 µm). RESULTS: Ninety eight (98) studies with 234 patients in the PPV group and 87 patients in the observation group were included in the review. Final VA (logMAR) and visual gain were respectively in PPV vs. observation groups: 1) small MH 0.37 ± 0.52 vs. 0.42 ± 0.56 (p=0.484) and -0.96 ± 0.83 vs. -0.49 ± 0.40 (p=0.005); (2) medium MH 0.58 ± 0.39 vs. 0.34 ± 0.34 (p=0.06) and -0.36 ± 0.42 vs. -0.74 ± 0.44 (p<0.001); (3) large MH 0.62 ± 0.42 vs. 0.59 ± 0.35 (p=0.337) and -0.31 ± 0.48 vs. -0.62 ± 0.37 (p=0.11). Small TMH had comparable closure time: 3.21 ± 2.52 months vs. 3.49 ± 4.43 (p=0.954) in the PPV and observation groups. Early and late PPV yielded comparable final VA 0.67 ± 0.66 vs. 0.54 ± 0.35 (p=0.576) and visual gain -0.58 ± 0.69 vs. -0.49 ± 0.48 (p=0.242) in the PPV and observation groups. CONCLUSIONS: PPV was very effective in closing TMH and VA gain in children throughout a wide range of hole size. Early and delayed PPV yielded similar anatomic and visual results. Observation and PPV yielded comparable final VA and closure time. Clinicians can choose either early PPV or delayed PPV when healing biomarkers are absent on periodic OCT.

Sclerectomy Reverses Nanophthalmic Optic Neuropathy.

Introduction: Nanophthalmos is characterized by a short axial length, a thick choroid, and a thick sclera. Unilateral symptomatic disc swelling in nanophthalmos presents both a diagnostic and a therapeutic challenge. Case Presentation: A healthy 59-year-old man reported a two-week-long abrupt vision reduction in his right eye. 20/100 best spectacle (+17.25 diopter) corrected visual acuity, unilateral widespread disc enlargement, central scotoma, and a slight color vision disruption without an afferent pupillary defect were among the positive findings in the right eye. Workup for neuro-ophthalmology was negative. Numerous consultations did not suggest any form of treatment for the patient. Review of the optical coherence tomography (OCT) indicated a small, crowded optic nerve head and substantial diffuse choroidal thickening with dome-shaped temporal peripapillary area with choroidal expansion. In addition to circumferential anterior four-quadrant 95%-deep sclerectomy from recti insertion to the vortices, radial nasal posterior sclerotomy reaching the optic nerve sheath was performed on the patient. After the procedure, 2 weeks later, the patient's vision returned, and it persisted until the 6-month follow-up. By OCT, the two eyes were comparable as far as disc contour and nerve fiber layer thickness. Conclusion: This form of sclerectomy, which aims at decompressing the oncotic choroidal pressure, is an effective treatment for compressive optic neuropathy in the context of nanophthalmos. Could sclerectomy assist in treating other optic neuropathies associated with peripapillary pachychoroid?

Surgical Approaches to Serous Retinal Detachment With Retina-Lens Touch in Eyes With Nanophthalmos.

Purpose:To describe the visual outcomes and problems that resulted from surgical treatment of nanophthalmic complete retinal detachment (RD) with retina-lens contact. Methods: A multicenter retrospective case series with deep sclerectomy as a treatment was performed. Results: Five cases had extensive deep sclerectomies, 3 with intended drainage of subretinal fluid (SRF). The RD resolved 1 week postoperatively in 4 cases and within 1 month in 1 case. The visual acuity improved from light perception to a median of 20/100. Three cases had longstanding lens touch beyond 1 year and improved VA to 20/100, 20/150, and hand motions, respectively. Complications included focal lens dialysis in 2 cases (passive drainage of SRF) and lens or intraocular lens dislocation in 1 case each (active drainage of SRF). Ultrasound biomicroscopy and anterior optical coherence tomography showed a very narrow angle and short zonules. Conclusions: Deep sclerectomy results in good anatomic and functional improvements in advanced cases of nanophthalmos exudative detachment, which is often considered to be incurable.

Integrated Life Skills Training and Executive Function Strategies in Children With Autism Spectrum Disorder in Qatar: A Pilot Study of a Randomized Controlled Trial.

Background and aim Executive function (EF) impairment is common in children with autism spectrum disorder (ASD). EF strategies are considered effective in improving the therapeutic outcomes of children with ASD. This study primarily aimed to explore whether integrating EF strategies combined with regular occupational therapy intervention is more effective in improving daily life skills (DLS) and sensory integration/processing (SI/SP) skills than regular occupational therapy alone in children with ASD and secondarily aims to assess treatment outcomes on improving visual motor integration (VMI) skills. Methods A total of 17 participants (13 males, mean age 4.29 years, standard deviation 0.66) completed the study. Following the baseline assessments, the participants were randomly assigned to the treatment group (45-minute once-weekly individual occupational therapy plus EF strategies) or control group (45-minute once-weekly individual therapy sessions alone). All participants received one intervention per week for 14 weeks. All children were systematically evaluated using a pediatric functional independent measure (WeeFIM) and the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess DLS, the Short Sensory Profile 2 (SSP2) to assess SP/SI, and the Beery VMI test (Beery VMI) to assess VMI. Assessments were conducted at baseline, seven weeks, and 14 weeks of treatment.  Results The analysis of the results between the treatment and control groups revealed that the treatment group had greater gains and significant differences in the mean values of both the WeeFIM and SSP2. In addition, notable distinctions were observed in the VB-MAPP transition subscale; although these differences did not reach statistical significance, they were clinically significant. Minimal differences were noted in the VMI between the two groups. Nevertheless, both groups showed statistically significant improvements across all outcome measures. Conclusions Our study provides preliminary evidence of the efficacy of EF strategies combined with regular occupational therapy for DLS, SP/SI, and VMI in children with ASD. The differences between the groups support further evaluation of the effectiveness of EF strategies for the next stage of a larger randomized clinical trial.

New insights in the multimodal imaging of retinitis pigmentosa.

Retinitis pigmentosa (RP) is a group of inherited rod-cone dystrophies, noted for a high genotypical and phenotypical heterogeneity.Traditionally, VA, visual field, and electroretinography have been used to assess RP progression. However, visual acuity and visual field tests are essentially subjective and, especially in the late stages of the disease, are unable to confidently reveal minor progression. Therefore, there is a need for novel examination modalities that rely on quantitative, structural measurements. In this regard, several non-invasive imaging techniques have been studied, including spectral-domain optical coherence tomography, optical coherence tomography angiography, and fundus autofluorescence. By correlating surrogate biomarkers with functional measurements of the disease, these techniques may be able to develop reliable outcome meters that can be used to gain a deeper understanding of the underlying causes of the disease and to assess the effectiveness of therapy even before an actual loss of vision occurs.In this review, we will summarize the recent imaging findings and biomarkers that have been identified in RP patients. Our goal is to provide information that can promptly aid in selecting patients for clinical trials and new gene therapies, monitoring the disease progression, and evaluating treatment outcomes.

Multimodal imaging in Best Vitelliform Macular Dystrophy: Literature review and novel insights.

Best Vitelliform Macular Dystrophy (BVMD) is a dominantly inherited retinal disease caused by dominant variants in the BEST1 gene. The original classification of BVMD is based on biomicroscopy and color fundus photography (CFP); however, advancements in retinal imaging provided unique structural, vascular, and functional data and novel insights on disease pathogenesis. Quantitative fundus autofluorescence studies informed us that lipofuscin accumulation, the hallmark of BVMD, is unlikely to be a primary effect of the genetic defect. It could be due to a lack of apposition between photoreceptors and retinal pigment epithelium in the macula with subsequent accumulation of shed outer segments over time. Optical Coherence Tomography (OCT) and adaptive optics imaging revealed that vitelliform lesions are characterized by progressive changes in the cone mosaic corresponding to a thinning of the outer nuclear layer and then disruption of the ellipsoid zone, which are associated with a decreased sensitivity and visual acuity. Therefore, an OCT staging system based on lesion composition, thus reflecting disease evolution, has been recently developed. Lastly, the emerging role of OCT Angiography proved a greater prevalence of macular neovascularization, the majority of which are non-exudative and develop in late disease stages. In conclusion, effective diagnosis, staging, and clinical management of BVMD will likely require a deep understanding of the multimodal imaging features of this disease.

Intraretinal Macroaneurysms and Multimodal Imaging: A Retrospective Analysis.

Purpose: To analyze the multimodal imaging characteristics of intraretinal macroaneurysms. Patients and Methods: Intraretinal aneurysms larger than 150 µm in diameter on fluorescein angiography were termed as intraretinal macroaneurysm and grouped as primary and secondary according to the absence or presence of any coexisting posterior segment diseases. Results: A total of 20 intraretinal macroaneurysms were observed in 18 eyes of 18 patients. Mean age of the cohort was 65.44 ± 9.14 years (Range; 49-82 years). Mean diameters of intraretinal macroaneurysms were 238.20 ± 61.12 µm (Range; 163.00-292.50 µm) and 242.72 ± 49.58 µm (Range; 168.00-328.00 µm) on fluorescein angiography and optical coherence tomography, respectively. Primary group had 10 eyes with 11 intraretinal macroaneurysms, whereas eight eyes had nine intraretinal macroaneurysms in the secondary group. Three of the eight eyes (37.5%) had diabetic retinopathy, four (50%), retinal vein occlusion, and one (12.5%), posterior uveitis in the secondary group. No statistically significant differences were found between the two groups in terms of age, sex, presence of intraretinal or subretinal fluid, the mean age, the mean central macular thickness, the mean distance of intraretinal macroaneurysms from the fovea, the mean diameter of intraretinal macroaneurysms measured on fluorescein angiography, and the mean diameter of intraretinal macroaneurysms measured on optical coherence tomography. Presence of intraretinal fluid was significantly more frequent than the presence of subretinal fluid in all eyes (p = 0.004). Conclusion: Intraretinal macroaneurysms are diagnosed more and more with the utilization of multimodal imaging techniques. We propose a simple classification system in order to help achieving a standardized terminology and ensure consistent understanding. The classification can be simplified as primary or secondary intraretinal macroaneurysm according to the absence or presence of the associated posterior segment disorders.

Recovery course of persistent posterior subretinal fluid after successful repair of rhegmatogenous retinal detachment.

PURPOSE: To investigate best corrected visual acuity (BCVA), subretinal fluid (SRF) absorption time or ellipsoid zone (EZ) restoration time and various variables in patients with persistent SRF after successful primary repair of rhegmatogenous retinal detachment (RRD). METHODS: This retrospective multicenter study allowed independent analysis of the healing pattern by two observers based on composite of serial cross-sectional macular optical coherence tomography (OCT) scans. Univariate and multivariate analyses were implemented. RESULTS: One hundred and three cases had persistent SRF after pars plana vitrectomy, scleral buckling, or pneumatic retinopexy. By univariate analysis, SRF resolution time correlated positively with the number of retinal breaks (p < 0.001) and with increased myopia (p = 0.011). Using multivariate analysis, final BCVA (log MAR) correlated positively with age, duration of RRD, initial BCVA (OR = 3.28; [95%CI = 1.44-7.47]; p = 0.015), and SRF resolution time (OR = 0.46 [95%CI 0.21-1.05]; p = 0.049). EZ restoration time was longer with increasing number of retinal tears (OR = 0.67; [95%CI 0.29-1.52]; p = 0.030), worse final BCVA, and presence of macula-off RRD (OR = 0.26; [95%CI 0.08-0.88]; p = 0.056). SRF resolution time correlated marginally with prone position. CONCLUSIONS: Residual posterior SRF is more common in eyes with multiple breaks or in myopic eyes. Final BCVA is better in younger subjects and in eyes with shorter duration of RRD. Persistent SRF is a self-limited disorder with a mean resolution of 11.2 months with good visual prognosis improving from a mean baseline logMAR of 1.08 to 0.25 at one year.

Is There a Link Between Vitreous Cortex Remnants and Anatomic Outcome of Vitrectomy for Primary Rhegmatogenous Retinal Detachment?

Purpose: To study the anatomic outcome of leaving vitreous cortex remnants (VCR) during pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD). Methods: The study comprised patients with RRD who had PPV by a single surgeon between January 2019 and December 2020 and followed for 6 months. After intravitreal injection of triamcinolone acetonide, the topographic pattern of VCR at the periphery (p) and macula (m) was divided into 2 types by extent: complete or 4 quadrants (pVCR4Q), and between 2 and 4 quadrants ≥2 quadrants (pVCR>2Q), or by location >1 inferior retinal quadrant (pVCR>1InfQ), and at the macula (mVCR). Anatomical failure or retinal re-detachment within 6 months after surgery was the primary outcome measures. The occurrence of grade C proliferative vitreoretinopathy (PVR) and epiretinal membrane (ERM) were used as secondary outcome indicators. Results: A 6-month prospective follow-up was performed on 103 patients. pVCR4Q was detected in 31 eyes, pVCR>2Q in 40 eyes, pVCR>1InfQ in 40 eyes and mVCR in 54 eyes. Recurrent RRD developed in 9 (8.7%) eyes, PVR grade C in 6 (5.8%) eyes and ERM in 11 (10.7%) eyes. According to multivariate regression analysis, the existence of any type of VCR did not correlate with anatomical failure, PVR or ERM. Conclusion: The initial success rate of PPV and the growth of PVR or ERM do not appear to be impacted by keeping VCR.

Animal injury characteristics following the 2020 ammonium nitrate explosion in the Port of Beirut.

PURPOSE: To describe the characteristics and veterinary management of animal casualties after an ammonium nitrate explosion in the Port of Beirut. METHODS: Retrospective evaluation of medical records from multiple veterinary organizations. RESULTS: Veterinary care was administered to 298 cats and 103 dogs, with 101 animals (25%) undergoing surgical procedures under general anesthesia. Glass injuries prevailed, with suturing performed in 98 animals (24.4%). Surgery was used to treat 31 animals (7.7%) with extremity fractures and 52 animals with tendon injuries (13.3%). Bodily burns were encountered in 19 animals (4.7%). Six animals (1.5%) lost their hearing entirely, while another 6 (1.5%) lost an eye. CONCLUSION: The joint coordinated work of veterinary groups and nongovernmental animal organizations reduced the number of injured animal fatalities. Of animals documented as having undergone treatment, 355 (88.5%) survived their initial injury assessment, and 46 (11.5%) died.

RPGRIP1 variant associated with pigmented paravenous chorioretinal atrophy.

PURPOSE: To report a case of Pigmented Paravenous Chorioretinal Atrophy (PPCRA) associated with a novel RPGRIP1 dominant variant. METHODS: Case report. The patient underwent multimodal retinal imaging, including spectral-domain optical coherence tomography (OCT), OCT Angiography (OCTA), blue-light autofluorescence (BAF), and ultra-widefield pseudocolor retinography and autofluorescence. Genetic testing was performed using next-generation sequencing. RESULTS: A 67-year-old male presented with a clinical suspicion of retinitis pigmentosa. His best-corrected visual acuity was 20/32 in the right eye and 20/200 in the left eye. On fundus examination, paravenous pigment clumping and chorioretinal atrophy were seen bilaterally, matching confluent hypoautofluorescent areas departing from the optic disc. This clinical presentation suggested a case of PPCRA. Genetic testing found a heterozygous deletion of nucleotide 631 (c.631del) in the RPGRIP1 gene, a frameshift variant that generates a premature stop codon (p.Ser211Valfs*64) and therefore results in a truncated or absent protein product. The variant was regarded as likely pathogenic (class IV). CONCLUSION: In this report, we describe a case of PPCRA in association with a novel, likely pathogenic c.631del, p.Ser211Valfs*64 variant in RPGRIP1, a gene that has been associated with Leber congenital amaurosis and cone-rod dystrophy. Our case expands the spectrum of genes associated with PPCRA and prompts further studies to ascertain the molecular etiopathogenesis of this disease.

Choroidal ischemia as one cardinal sign in giant cell arteritis.

PURPOSE: To describe chorioretinal signs in a case series of Giant Cell Arteritis (GCA). METHODS: This is a multicenter retrospective observational case series with GCA that presented with a headache and an abrupt, unilateral loss in vision. Workup included temporal artery biopsies, intravenous fluorescein angiography, optical coherence tomography (OCT), optical coherence tomography angiography (OCTA), blood levels of erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). RESULTS: There are a total of 8 GCA instances presented. Average age was 74.5. (Range 68-83 years). The patients reported that one eye's visual loss had suddenly started, along with a fresh headache and other systemic symptoms. Eight patients exhibited choroidal ischemia, five paracentral acute middle maculopathy (PAMM) lesions, five cotton wool spots, four anterior ischemic optic neuropathy, and one central retinal arterial occlusion at the time of presentation. The average ESR at presentation was 68 mm/hr (range 4-110), and 4/6 individuals had a significant increase. The mean CRP level was 6.2 mg/dL (range 2.0-15.4), and the level was always over the normal range. All patients' temporal artery biopsies were positive. CONCLUSION: Alongside PAMM lesions, cotton wool spots, anterior ischemic optic neuropathy, and central retinal artery occlusion, choroidal ischemia is a key angiographic indicator in the diagnosis of GCA. It may be crucial to recognize these typical ischemic chorioretinal signs while diagnosing GCA.

Recovery course of foveal microstructure in the nonsurgical resolution of full-thickness macular hole.

PURPOSE: To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH). METHODS: By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS). RESULTS: The healing (mean±standard deviation in months) most involved fusion at the level of the outer nuclear layer (ONL) (6.3±10.5) followed by restoration of ELM (9.1±13.8), and lastly, by IS/OS regeneration (13.1±19.5). In severe blunt ocular trauma, healing was fast and involved subretinal zipper glue-like reapposition with resulting outer retinal atrophy. Best spectacle-corrected visual acuity correlated with normalization of the clivus (p=0.012), faster ELM (p=0.006), and IS/OS reconstitution (p=0.024). Recurrence of FTMH occurred when the healing was halted (3 eyes) or was aberrant by lamellar hole epiretinal proliferation (LHEP) (3 eyes) or by the persistence of VMT (1 eye). CONCLUSION: Recovery sequences proceeded from the ONL to the deeper layers with BCVA correlating absolutely and temporally with the restoration of outer retinal layer integrity.

Analysis of ocular injury 1-year outcome in survivors of Beirut Port ammonium nitrate blast.

PURPOSE: Ascertain the 1-year outcome of patients who sustained open eye injuries from the Beirut Port ammonium nitrate (AN) explosion, one of the most powerful non-nuclear explosions in history. METHODS: Retrospective chart review of the operated eyes in 2 major eye hospitals. RESULTS: Out of 42 patients with open globe injury that was originally sutured, 29 patients (34 eyes) were followed at the 1-year mark. The initial vision in logMAR (mean ± SD) was 2.93 ± 0.87 (hand motion equivalent) and the final vision was 1.80 ± 1.47 (counting finger 2 m equivalent). No light perception (NLP) vision was noted in 12 eyes on presentation and 10 eyes remained so, while 2 eyes reached light perception (LP) vision. Eight eyes had an intraoperative expulsive choroidal hemorrhage (7 NLP and 1 LP both pre- and postoperatively), and 6 of the 8 developed phthisis. All eyes that developed phthisis had NLP preoperatively and postoperatively. Ocular Trauma Score (OTS) correlated inversely with both initial and final vision (p < 0.001). Zone of injury inversely correlated with initial vision (p = 0.02) and positively with final vision (p < 0.001). Final vision was significantly worse in zone 3 vs. zones 1 and 2 (3.2 ± 0.5) vs. 0.9 ± 1.1) (p < 0.001) injuries, as was the initial vision (3.3 ± 0.5 vs. 2.7 ± 0.8; p = 0.002). CONCLUSION: The OTS, which provides prognostic information for serious ocular trauma, also yields valuable prognostic information for AN-associated ocular injuries. Expulsive choroidal hemorrhage and NLP vision at presentation remain very poor prognostic signs.

A hypothetical therapeutic effect of light peripheral panretinal photocoagulation in neovascular age-related macular degeneration.

Background: Vascular endothelial growth factor (VEGF) is a significant modulator of ocular angiogenesis, including that of neovascular age-related macular degeneration (nAMD). Intravitreal injection of anti-VEGF is the benchmark treatment for most retinal vascular diseases, including nAMD, diabetic maculopathy, and macular edema secondary to retinal venous occlusion. Anti-VEGF treatment is a high-frequency, time-consuming, non-cost-effective therapy, especially in countries and regions with limited resources. This treatment is easily restricted, and in practice, maintaining long-term periodic care is challenging for patients. Hypothesis: Light peripheral panretinal photocoagulation (PPRP) is applied in a mild form (barely visible mild light gray mark) anterior to the equator so as not to jeopardize the visual field. PPRP lessens the ischemia that causes neovascularization and decreases the metabolic demand in the peripheral retina. PPRP reduces serum angiopoietin-2 and VEGF levels in patients with type 2 diabetes mellitus with proliferative diabetic retinopathy. We propose using light PPRP to suppress VEGF secretion, aiming to attenuate the VEGF drive and halt choroidal neovascular growth in eyes with nAMD. Our regimen is based on two concepts: first, nAMD is a diffuse or generalized disease that affects the posterior segment; and second, PPRP is very effective in regressing diabetic retinopathy. PPRP has reportedly been successful in cases of macular edema (diabetic or following venous occlusion) resistant to VEGF antagonists. Light PPRP may be used as prophylaxis, adjunctive treatment, or monotherapy in nAMD when intravitreal injections of VEGF antagonists are not feasible. Conclusions: The established light PPRP therapy could be promising as a one-time, cost-effective therapy or prophylaxis in patients with nAMD or at high risk. This proposed modality could be suitable for patients who have injection phobia or prefer a one-time affordable therapy to the long-term monthly visits to retinologists. Future trials are necessary to verify the safety and efficacy of this proposed treatment modality in selected patients with nAMD.

Familial Mediterranean fever associated frosted branch angiitis, retinal vasculitis and vascular occlusion.

OBJECTIVES: To analyse the entity of retinal vasculitis, including frosted branch angiitis (FBA), or retina vascular occlusion in patients with familial Mediterranean fever (FMF). METHODS: Retrospective collaborative case series using invitation by email to uveitis specialists around the Mediterranean basin. This series was combined with a literature review. Exclusion criteria included infectious diseases, Behçet's disease or other autoimmune diseases. RESULTS: A total of 16 patients (21 eyes) had FMF and retinal vasculitis (FBA 11 patients, mild retinal vasculitis 5 patients). The mean age at onset of vasculitis was 29.5 ± 13.4 (range 9-62) with a female to male ratio of 9 to 7. In 19 eyes treated with various forms of corticosteroid and/or immunosuppression, the mean initial spectacle-corrected visual acuity improved from 6/194 to 6/10.5 at the last mean follow-up of 29.0 ± 34.9 months (p < 0.001). The most common FEVR mutations were M680I and M694V. In addition, retinal vascular occlusions included one case of central retinal artery occlusion and one case of branch retinal artery occlusion. CONCLUSION: FBA and milder forms of retinal vasculitis are associated with FMF. Therapy involves an increase in colchicine dosage in early cases, a long period of oral corticosteroid, intravitreal dexamethasone implant or periocular corticosteroid in select cases, and combination therapy with systemic immunosuppression in severe cases. FMF needs to be included in the differential diagnosis of retinal vasculitis.

Associations in corticocapsular adhesions.

OBJECTIVES: To determine the patient-related factors that contribute to intraoperative corticocapsular adhesions (CCA) during phacoemulsification cataract extraction (PCE). METHODS: Prospective, single surgeon, multi-year study of consecutive patients undergoing PCE was performed. At the conclusion of each procedure, the surgeon recorded the CCA and perceived surgeon stress score. Patient variables included gender, age, diabetes mellitus, intake of oral alpha blockers, floppy iris, laterality, pseudo-exfoliation, and intraocular lens power. RESULTS: During the 10-year study, 1097 eyes underwent surgery and CCA was diagnosed intraoperatively in 41 eyes. On multi-variable analysis, the following patient characteristics were associated with intraoperative CCA: diabetes mellitus (p = 0.002), age >80 years (p = 0.002), presence of posterior capsular cataract (p = 0.046), severe nuclear sclerosis (p = 0.004), and absence of pseudo-exfoliation (p = 0.043). CONCLUSION: Diabetes mellitus, advanced age and posterior subcapsular cataract are associated with CCA necessitating generous repetitive hydrodissection.
