Introduction. Reduced corneal transparency leads to dissipation of energy of the femtosecond laser (FSL), which may complicate the formation of the intrastromal incision and limits the use of FSL in eyes with corneal opacities and scars. The purpose of this work is to demonstrate the possibility of successful ReLEx SMILE in a patient with superficial corneal opacity located in the paracentral zone. Case report. Patient R., 29 years old, complained of decreased vision in both eyes since childhood. Visual acuity OD = 0.1 sph –2.75D = 1.0; OS = 0.1 sph –3.50 D cyl –0.75D ax 165° = 1.0. Biomicroscopy of the right eye visualized a superficial semi-transparent corneal opacity of 5 x 3 mm located at 5.30–6 hours at a distance of 1.3 mm from the optical center. According to the anterior segment optical coherence tomography (AS-OCT) the depth of the opacity was 73–78 microns and was limited by the Bowman’s membrane. ReLEx SMILE for myopia correction was performed on both eyes with 6.7 mm lenticule diameter at a depth of 120 µm, which covered the opacity area by 1.1 mm. The surgery was standard and uncomplicated. Seven days postoperatively the patient did not complain. Uncorrected visual acuity (UCVA) was 1.0 for both eyes (and binocularly it was 1.2). According to the AS-OCT data, a hyperreflective line of the interface zone was visualized on the right eye at the depth of 141–147 µm; the opacified superficial corneal layers were detected in the lower paracental zone over the interface line. In one month after the surgery the visual acuity did not change: UCVA = 1.0 in both eyes (binocularly 1.2). Conclusion. ReLEx SMILE technology can be considered as one of the options for myopia correction in patients with superficial corneal opacity located in the paracental zone. More observations are required to evaluate the effectiveness of this technology on corneas with paracentral opacities different in sizes and located at different depths.

Purpose. To describe a case of 3 refractive procedures performed in one eye over 2 decades.Methods. Case report.Results. A 41-year-old patient presented for refractive surgery evaluation. His ocular history includes bilateral radial keratotomy performed 21 years ago for moderate myopia: spherical equivalence of −4.25 D bilaterally. Postoperative uncorrected visual acuity (UCVA) was 20/30; however, over time he developed a hyperopic shift and UCVA decreased to 20/40 in the right eye. Thus, laser-assisted in situ keratomileusis (LASIK) was performed at an outside institution 6.5 years later, and the patient had initial improvement of UCVA to 20/25. Due to a change in refractive error, the patient underwent uneventful astigmatic keratotomy 13 years after LASIK in the right eye, and 1.5 years after surgery best-corrected visual acuity was 20/25 with manifest refraction of −1.00+5.50×134°.  Conclusion. We report the outcomes and natural refractive progression in a patient who underwent three corneal refractive procedures over two decades. This case underlines the difficulties of long-term management of post-RK hyperopia and astigmatism.

Purpose: to evaluate the safety and clinical efficacy of the Femto-LASIK refractive surgery performed under local (topical) anesthesia in children and adolescents with anisometropic and refractive amblyopia against a background of mixed astigmatism, medium and high hypermetropia with hypermetropic astigmatism.Patients and methods: 28 children (28 eyes) aged from 7 to 16 years (av. age — 13.6 ± 2.1 years old) were operated under local anesthesia by the FemtoLASIK method. The degree of anisometropy was from 3.25 to 5.21 (average — 4.27 ± 0.53 D). Uncorrected visual acuity averaged 0.21 ± 0.07, corrected one — 0.41 ± 0.1. Psychological history of patients and readiness for operative treatment of the disease were found out during the diagnostic examination. Based on the Spielberger-Khanin technique, the level of personal and reactive anxiety was determined, allowing identifying patients for surgical intervention under topical anesthesia. The surgeon assessed the comfort of the operation. During the first postoperative examination, the developed questionnaire was used to assess the comfort level of the patient during surgical treatment.Results. During the surgical intervention and in the postoperative period there were no complications. The behavior of all patients during the operation can be considered adequate. The duration of the operation slightly exceeded the duration of FemtoLASIC in adults. Uncorrected visual acuity in the first day after the operation averaged 0.39 ± 0.08, in 6 months — 0.61 ± 0.1, which is 80% higher than the baseline indices. After 6 months, the equivalent of anisometropia was 0.69 ± 0.12 D, that is, the refraction of the operated eye approached the value of the paired eye. In 60.8% of patients, the sensations during the operation corresponded to the level of “comfortable”. The surgeon’s assessment of the conditions for performing operations as ‘satisfactory” was noted in 92.9%.Conclusion. The use of topical anesthesia in refractive surgery in children with an initially low level of anxiety is an effective, safe and predictable method of anesthesia, allowing to conduct surgery in comfortable conditions for both the patient and the surgeon, with a high functional result.

A 40-year-old One-eyed patient (right eye) acuity history of post-traumatic burst in his left eye at the age of 6 years. Consult for a decrease of vision on his right eye that has progressed for 3 weeks. Ophthalmic examination found visual acuity: 2/10 P10 in the right eye, the left eye presents enophthalmos with an opacified cornea; the anterior segment was normal in the right eye, fundus examination shows hyalitis graded 1+, papillary edema, peripapillary hemorrhages and stellar macular exudates, cottony nodules, copper arteries with vascular sheathing of the superior temporal branch and areas of retinal ischemia (Figure 1). The inflammatory and serological assessment is negative. Fluorescein retinal angiography shows papillary diffusion of fluorescein and vasculitis (Figure 2). We find serous retinal detachment on OCT (Figure 3). The general examination found bipolar aphthosis. The diagnosis of Behçet’s disease is retained. Treatment with immunosuppressants allowed the regression of papillary edema with persistence of some macular exudates and great improvingin visual acuity.

A 65-year-old patient with history of keratoconus, mild cataract and penetrating keratoplasty over 30 years ago developed corneal oedema subsequent of graft failure with best corrected visual acuity (BCVA) of counting fingers. He underwent a successful cataract surgery combined with a 7.25 mm Descemet’s Membrane Endothelial Keratoplasty (DMEK) with Sodium Hexafluoride (SF6) gas. His cornea remained oedematous inferiorly at 4 weeks, despite two subsequent re-bubbling due to persistent DMEK detachment inferiorly. This was managed by three radial full thickness 10-0 nylon sutures placed in the inferior cornea along with intracameral injection of air. Following this, his anterior segment ocular coherence tomography (OCT) confirmed complete attachment of the graft, and the sutures were removed 4 weeks later. Unaided visual acuity was 20/63 and BCVA was 20/32 after 8 months. DMEK suturing can be helpful in persistent DMEK detachments, which is refractory to repeated re-bubbling due to uneven posterior surface of previous PK.

Abstract Introduction Corona virus disease (COVID-19) pandemic can cause myriad of ocular manifestations. We report a case of unilateral multi focal central serous retinopathy, post COVID-19 infection in an Asian Indian female. Case presentation A 42-year-old female presented to us with unilateral blurring, in the right eye (OD), 12 days after COVID-19 infection. She had fever, chills, shortness of breath and cough with tiredness and was COVID- RT PCR positive. She was administered intravenous and oral antibiotics with injection heparin/remdesivir, during her 7 day stay at the hospital. She was also on steroid inhalers. She had no systemic history of note. On ocular evaluation, her corrected distance visual acuity was 20/40 in OD and 20/20 in left eye (OS). Anterior segment was normal. Anterior vitreous was clear. Fundus examination of the OD showed central serous retinopathy (CSCR) with OS being normal. Conclusion CSCR can occur post COVID-19 due to steroid administration and physicians administering it should be aware of this and refer the patients to an ophthalmologist earlier.

Loss Of Visual Acuity

We report the case of an 18-year-old patient who consults for a loss of visual acuity in the right eye for 1 year. On clinical examination, visual acuity is 20/100. Eye tone is 12 mmhg. Examination of the anterior segment shows the existence of a cataract made up of whitish opacities corresponding to a congenital cerulean cataract (Figure 1). The treatment consisted of a cataract cure by phacoemulsification with good progress. Cerulean cataract is a rare congenital form of bluish tint, made up of whitish opacities in concentric layers with a radial arrangement at their center. Visual acuity is fairly good in childhood but may deteriorate later. In the literature, the incidence of cataracts in Down’s children ranges from 5% to 50%. In previous studies of congenital or infantile cataract, 3-5 % of cases were associated with Down’s syndrome [1].

ABSTRACT Purpose To report the clinical course of a typical young patient presenting with asymmetric keratoconus (KC), that demonstrates that stabilization of the ectatic process is possible without cross-linking (CXL) procedure. Methods Case report and review of the literature. Results A 17-year-old male patient was referred due to the diagnosis of keratoconus. Patient complained of loss of vision in the left eye (OS). Uncorrected distance visual acuity (UDVA) was 20/25+ in the right eye (OD) and 20/80 in the left eye; wavefront-assisted manifest refraction gave best corrected distance visual acuity (CDVA) of 20/20 in OD and 20/40 in OS. The diagnosis of keratoconus was confirmed with Placido disk-based topography (Oculus Keratograph 4), and Pentacam HR corneal tomography (Oculus Optikgeräte GmbH, Wetzlar, Germany). Femtosecond laser-assisted intracorneal ring segment (ICRS) implantation was performed in the left eye and treatment for allergy was prescribed for both eyes, along with patient education and advice not to rub the eyes. After 3 months, significant improvement was observed on UDVA (20/30) and CDVA (20/20) in the left eye. Topometric and tomographic stability of ectasia was observed in the right eye in a 4-year follow-up. Conclusion Intracorneal ring segment caused significant regularization of the corneal shape and improvement on visual acuity. Ectasia stability was achieved with no need for CXL, despite the patient's young age. This case raises the point that the indication of CXL for every keratoconic patient should be reconsidered.

The majority of cases of orbital emphysema are due to trauma. Complications are rare, and therefore, the need for surgical intervention is uncommon. We present the first case of which we are aware in which nontraumatic orbital emphysema led to orbital compartment syndrome and subsequent optic nerve dysfunction. The patient underwent emergency needle decompression. A 51-year-old man presented to the Emergency Department with right-sided unilateral proptosis, reduced visual acuity, and binocular diplopia. This occurred after performing a Valsalva manoeuvre with no history of head trauma. He also mentioned that over the past year he had experienced multiple episodes of transient proptosis occurring after Valsalva manoeuvres. Visual acuity in the right eye was reduced to 6/21. A relative afferent pupillary defect was present and intraocular pressure (IOP) was 12 mmHg. The CT scan showed significant orbital emphysema in the medial aspect of the right orbit. Needle decompression was performed resulting in immediate resolution of his symptoms. This case demonstrates that, in cases of orbital emphysema, a lack of a history of trauma and a normal IOP cannot always be used to rule out serious pathology.

ABSTRACT Purpose To report refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18 years of age with progressive keratoconus. Materials and methods In this retrospective study, we enrolled 31 eyes of 21 children aged 11 to 17 years that underwent corneal riboflavin-ultraviolet A induced CXL due to progressive keratoconus at three different ophthalmology departments in Israel. They were followed for 3 to 48 months (average 23 ± 13.6 months). Evaluated parameters were uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), manifest refraction, pachymetry, slit- lamp examination and corneal topography at baseline and at 1,3,6,12,24 and 48 months. Results We found a nonsignificant improvement in UCVA and BSCVA with a small reduction of manifest cylinder and no significant change in spherical equivalent or K-values. Following CXL, stability of UCVA and BSCVA at the last follow-up examination was found in 71 and 77% of treated eyes, respectively. No permanent adverse events have been recorded throughout the study period. Conclusion In our series, CXL was a safe procedure in the pediatric population. Stabilization of progressive keratoconus was achieved in visual acuity, refractive and topography parameters with no improvement in corneal indices in contrary to adult CXL treatment.
