ABSTRACT
Purpose: We present the case of a severe golf related ocular injury that affected the anterior and posterior segment. Treatment included primary surgical closure of the traumatic wound and secondary reconstruction of the iris-lens-diaphragm to correct aphakia and traumatic mydriasis and iridodialysis. Observations: A 62-year-old woman presented to our clinic with severe ocular contusion after she had been hit by a golf ball in the right eye. We observed iridodialysis, traumatic mydriasis and luxation of the crystalline lens into the vitreous body as well as Berlin's edema and retinal tears. The patient underwent primary surgical closure of the traumatic wound and, 6 months later, combined Intraocular lens (IOL) and Customflex ArtificialIris (AI, HumanOptics, Erlangen, Germany) implantation. Uncorrected distance visual acuity was hand movement after primary surgical closure of the traumatic wound. After secondary reconstruction of the iris-lens-diaphragm, corrected distance visual acuity was 0.30 logMAR. Subjective impairment from glare could effectively be reduced and the patient was very satisfied with the aesthetic result. Conclusions and Importance: Combined AI and IOL implantation can successfully restore visual acuity and reduce sensitivity to glare while providing an excellent aesthetic result in patients with a history of severe blunt ocular trauma, even in cases with a poor visual acuity prognosis.
ABSTRACT
This paper explored epidemiology and evaluation of posterior segment involvement as prognostic factors for functional outcome of patients with open globe injuries. A retrospective analysis of 151 patients with open globe injuries was conducted. Pre- and postoperative-corrected distance visual acuity (CDVA), epidemiologic data, classification of the injuries including the ocular trauma score (OTS), performed surgeries, intraocular pressure (IOP) and correlation analyses between OTS and postoperative CDVA were obtained. A total of 147 eyes were included in the study. Mean age was 42.9 ± 22.2 years, 78.2% were male, and 36.7% of injuries occurred in the workplace. Thirty-eight patients (25.9%) had intraocular foreign bodies. Concerning injury location, 51.7% of the injuries were located in zone I (cornea, corneoscleral limbus), 15.0% in zone II (up to 5 mm posterior the sclerocorneal limbus) and 32.0% in zone III (posterior of zone 2). Affected structures were eyelids (17.7%), cornea (74.8%), iris (63.9%), lens (56.5%), sclera (48.3%), retina (47.6%) and optic nerve (19.7%). Mean preoperative CDVA was 1.304 ± 0.794 logMAR and 1.289 ± 0.729 logMAR postoperatively (p = 0.780). Patients with posterior segment involvement had significantly worse postoperative CDVA than patients without (1.523 ± 0.654 logMAR vs. 0.944 ± 0.708 logMAR, p < 0.01). Predictive factors for good visual outcome of open globe injuries are good initial CDVA and ocular trauma affecting only zone I and II.
ABSTRACT
The efficacy of the 0.19-mg fluocinolone acetonide (FAc) intravitreal implant (ILUVIEN) in the treatment of non-infectious uveitic macular edema (UME) was assessed on twenty-six patients (34 eyes) with non-infectious UME between 2013 and 2020, in a mean follow-up of 18 ± 19.3 (mean ± SD) months. Macular edema was resolved in 24 (70.6%) cases. Five of these eyes had a relapse after 23.2 ± 14 months. Three FAc reinjections were performed and a drying of the macula was observed. After FAc implantation, 24 eyes (70.6%) were completely dry; central retinal thickness (CRT) decreased in 6 eyes (17.6%), but residual intraretinal fluid was still evident. In 20 eyes (58.5%), visual acuity (VA) improved (from +1 to +5 lines) and remained stable in 9 eyes (26.5%). Thirty eyes (88.2%) were pseudophakic at baseline and four were phakic. Three of these eyes had a cataract prior to therapy and the other developed a cataract 2.5 years after the FAc implant was administered. There was an overall increase in intraocular pressure (IOP; +4.4 ± 3.7 mmHg) and eye drops were required in three eyes. The FAc implant led to long-term improvements in mean CRT and VA, and that the side-effect profile was manageable in a clinical setting in patients with non-infectious UME.
ABSTRACT
PURPOSE: Binocular traumatic or atraumatic iris defects can lead to an increased sensitivity to glare and cosmetic disfigurement. Surgical iris reconstruction is one approach to alleviate these problems. We report the clinical outcomes after medically indicated bilateral implantation of an Artificial Iris prosthesis in three patients with binocular iris defects with different etiologies. OBSERVATIONS: All three patients underwent binocular CUSTOMFLEX ArtificialIris (AI) (HumanOptics AG, Erlangen, Germany) implantation with simultaneous cataract surgery. Corrected distance visual acuity (CDVA), manifest refraction, Contrast sensitivity, endothelial cell density and subjective visual impairment as well as subjective cosmetic disfigurement were measured pre- and postoperatively. CDVA remained stable or improved in all three patients. We observed an increase in contrast sensitivity and reduction of glare sensitivity in two patients. All patients reported satisfaction with the cosmetical result after the implantation. CONCLUSIONS AND IMPORTANCE: The bilateral Artificial Iris implantation is an effective therapeutic option to reduce glare sensitivity and to achieve an aesthetically pleasing result also in selected patients with binocular traumatic or atraumatic iris defects.
ABSTRACT
PURPOSE: We present the case of a 49-year old female who underwent bilateral exchange of a supplementary trifocal sulcus-fixated intraocular lens (IOL) to correct a residual refractive error. Six months beforehand, she had been treated for hyperopia, astigmatism and presbyopia with a duet procedure to create reversible trifocality. OBSERVATIONS: Refractive lens exchange with combined implantation of a monofocal toric IOL into the capsular bag and a trifocal supplementary IOL into the ciliary sulcus (duet procedure) had been performed in both eyes. Decreased uncorrected distance visual acuity due to the refractive outcome of -0.75 diopter sphere (DS)/-0.25 diopter cylinder (DC)x10° for the right eye and -1.0DS for the left eye as well as the perception of photic phenomena were inacceptable for the patient. In the second operations, we exchanged the supplementary IOLs to correct the residual refractive error and achieve the target refraction of emmetropia. UDVA increased from 0.50 logMAR in both eyes prior to the IOL exchange to -0.22 logMAR in the right eye and -0.20 logMAR in the left eye. Binocular uncorrected near and intermediate visual acuity were -0.10 logMAR and 0.00 logMAR respectively after exchanging the sulcus-fixated supplementary IOLs, allowing for complete spectacle independence. CONCLUSIONS: This case demonstrates one of the most important benefits of the duet procedure: the possibility, if necessary, to easily remove or exchange the supplementary IOL from the ciliary sulcus. The duet procedure offers a safe treatment option in the event of postoperative complications like residual refractive error or intolerance to a multifocal optic.
