Christmas tree cataract is a rare type of lens opacification which is usually age related, though several cases have been seen in patients with myotonic dystrophy. It consists of highly refractive multicolored needle-shaped opacities within the deep cortex of the lens (1). The exact mechanism of crystals is not exactly known, but different theories have been proposed. Shun-Shin et al. postulated that the crystals were most likely of cystine due to an age-related aberrant breakdown of lens induced by elevated Ca++ levels (1).  According to Anders and Wollensak, the crystals were cholesterol in nature and were the result of lens metabolism (2). A 64 years old female presented with reduced visual acuity in her right eye. Her best corrected visual acuity (BCVA) in right eye was 6/10 Snellen chart. Slit lamp examination after pupillary dilatation revealed highly reflective, polychromatic, needle-shaped crystals in the temporal and inferior cortex of the right lens with associated nuclear sclerosis. This aspect of glittering multi-colored opacities varying with the angle of light incidence resembles the colored lights decorating the Christmas tree(Fig.1). As the visual acuity was significantly reduced and there were no other associated ocular pathologies, we decided for a cataract surgery in the right eye. Since the crystals are highly refringent and change considerably the viewing of the surgeon during the procedure, an increased time of surgery should be avoided (3) (4). Uneventful extracapsular phacoemusification of the lens with monofocal artificial intraocular lens implantation within the capsular bag was performed with very good results.

Introduction: Torsional ultrasound energy and burst mode interrupted energy delivery system are recent advancementsin the technique of phacoemulsification surgery. It has been reported that both these advancementshelpto reduce corneal wound burn and thermal induced endothelial cell loss and thereby helps to achieve excellent early postoperative visual outcome Objectives: To evaluate the efficacy of burst mode torsional phacoemulsification surgery in age-related cataract. Materials and Methods: Prospective observational study of 120 cases that underwent phacoemulsificationcataract surgery in which torsional energy was used in burst mode. Phacoemulsification was performed by “vertical –chop” technique. Intraoperatively corneal wound burn, Descemet’s membrane detachment, posterior capsule ruptureetc.were evaluated. Postoperatively corneal oedema, best corrected visual acuity, cystoid macular oedema were evaluated. Postoperatively eyes were examined at day 1, 1 week, 6 weeks and 3 months. Results: Mean age of the patients was 57.28± 8.20 years. Most of the patients 81(67.5%) had nuclear sclerosis grade-II cataract.Intraoperatively, moderate wound burn occurred in 02(1.6%) eyes, localized Descemet’s membrane detachmentin 03(2.5%) eyes and posterior capsule rupture occurred in 03(2.5%) cases. Postoperatively, moderate and severe corneal edema was found in 06(5.0%) and 04(3.3%) eyes respectively at day 1. At the end of 3 months follow-up, 114(95%) eyes maintained a best corrected visual acuity of ≥ 6/18, of which 109(90.8%) eyes achieved ≥ 6/9. Conclusion: Burst mode torsional phacoemulsfication is a very effective and advanced technique of cataract surgery. Intraoperative complications are very less and visual outcome is excellent.

Herpes zoster ophthalmic is a common condition in the elderly or in the immunocompromised people. We present the case of a 32-yearold female patient, without any particular history, who consulted the emergency room for a red right eye with major chemosis, palpebral edema, and decreased visual acuity. There was also a crusty rash in the V1 territory, suggesting herpes zoster. Visual acuity was 2/10 in the right eye and 10/10 left eye (Figure 1 and 2). Examination at the slit lamp revealed a non-hypertensive granulomatous anterior kerato-uveitis of the right eye. Given the severity of the lesion, an immunodepressive background was suspected, HIV serology came back positive.

A 40-year-old male patient referred to the ophthalmologic emergency room for complaints of diminution of vision in the left eye since three months after a trauma. Examination of the left eye showed a corrected visual acuity of 20/70. Slit-lamp examination revealed a rosette cataract (Figure 1). The patient underwent phacoemulsification with implantation of an IOL in the bag. The rosette cataract is a posterior subcapsular cataract due to a violent contusion with a closed globe. It can develop in the hours that follow, or on the contrary several years later.

The purpose of this report is to describe a case of bilateral foveal hypoplasia in the absence of other ophthalmological or systemic manifestations. We characterize the case of a 9-year-old Caucasian male who underwent full ophthalmologic examination, including functional measures of vision and structural measurements of the eye. Best corrected visual acuity was 0.50 logMAR in the right eye and 0.40 logMAR in the left eye. Ophthalmoscopy revealed a lack of foveal reflex that was further investigated. Optical coherence tomography (OCT) confirmed the absence of foveal depression (pit). OCT images demonstrated the abnormal structure of retina in a region in which we expected a fovea; these findings were decisive to determine the cause of reduced acuity in the child.

Importance: To provide new insights into aflibercept effect in non-naive-treated patients with neovascular age-related macular degeneration. Purpose: To assess the efficacy of intravitreal aflibercept in patients with neovascular age-related macular degeneration without optimal response to previous anti-vascular endothelial growth factor A therapy. Design: Single-arm, multi-centre, prospective study. Participants: Patients ⩾50 years with active neovascular age-related macular degeneration, best-corrected visual acuity between 20/32 and 20/320 with suboptimal response to ranibizumab or bevacizumab. Methods: Aflibercept was administered monthly (3-first months), and bimonthly thereafter until month 8. Anatomical and functional outcomes were assessed. Main outcome measure: Percentage of eyes without intra or subretinal fluid on optical coherence tomography after 3-monthly loading doses of aflibercept. Results: A total of 46 patients were included. At week 12, 45.7% (95% confidence interval: 31.5%–60.1%) of eyes showed no fluid on optical coherence tomography. The mean (standard deviation) best-corrected visual acuity increased from 65.1 (8.3) to 69.6 (8.1) letters (+4.5 (5.8) p < 0.0001) and was stabilized at week 40 as compared to baseline. Mean central macular thickness decreased from 430 (119) µm to 323 (100) µm at week 12 (–107 (90) µm, p < 0.0001) and was reduced at week 40 (–46 (111) µm, p = 0.0056). At week 40, 21.7% (95% confidence interval: 9.8%–33.7%) had no fluid. There was a case of presumed noninfectious endophthalmitis that was successfully managed. Conclusion: Almost half of patients presented no fluid on optical coherence tomography at week 12, and there was a clinically significant improvement in best-corrected visual acuity. At week 40, one in five patients did not show intra or subretinal fluid, central macular thickness decreased and best-corrected visual acuity was stabilized compared to baseline.

Purpose: To report the morphological and clinical features of a case of pachychoroid disease with focal choroidal excavation and large choroidal excavation complicated by choroidal neovascularization. Methods: The patient underwent a complete ophthalmologic examination including best-corrected visual acuity assessment, anterior segment and dilated fundus examination, fluorescein and indocyanine green angiography, and spectral-domain optical coherence tomography. Results: During the previous follow-up, the 57-year-old man received a diagnosis of central serous chorioretinopathy in the right eye with a late appearance of a choroidal neovascularization. The best-corrected visual acuity was 20/125 and 20/20 in the right and left eye, respectively. Dilated fundus examination, fluorescein angiography, and indocyanine green angiography confirmed a large subretinal fibrosis corresponding to the evolution of the choroidal neovascularization in the right eye. Spectral-domain optical coherence tomography clearly demonstrated in the right eye a large choroidal excavation below the fibrotic neovascular lesion with multiple hyperreflective foci inside the cavity, and in the left eye, a conforming focal choroidal excavation, bowl-shape type, associated with increased choroidal thickness with pachyvessels. Conclusion: Large choroidal excavation has been rarely reported. Although the pathogenetic mechanisms leading to the formation of large choroidal excavation are still only hypotheses, a combination of primary degenerative inflammatory factors sustaining the focal choroidal excavation formation and disruptive process of the choroidal neovascularization could be retained responsible for the large choroidal excavation.

Introduction. To report a case of anterior sclera staphyloma and vitreous hemorrhage occurring over 38 years after bilateral cataract surgery.Methods. A 58-year-old man presented with anterior sclera staphyloma and vitreous hemorrhage in the right eye, after bilateral cataract surgery, over 38 years ago. We performed combined anterior sclera staphylectomy and vitrectomy of right eye for anterior sclera staphyloma and vitreous hemorrhage.Results. Forty-eight months after the combined surgery, best-corrected visual acuity was 0.3 (+10.00/−4.50 × 60) with eutopic stitches of the corneoscleral junction on the superior nasal quadrant and a stable ocular surface.Conclusions. This is the first reported case of anterior sclera staphyloma with vitreous hemorrhage successfully managed by combined surgery.

Purpose: To describe a case of macular telangiectasia type 2 (MacTel) presenting with decreased vision due to intraretinal/sub-internal limiting membrane (ILM) hemorrhage in the absence of neovascularization. Method: Clinical examination and multimodal imaging were performed. Results: A 65-year-old female presented with blurred left vision, recording 20/160 in that eye. There was intraretinal hemorrhage at the left macula centrally, with sub-ILM hemorrhage superiorly and inferiorly. Optical coherence tomography (OCT) showed no evidence of subretinal neovascularization. Imaging of the right macula was consistent with MacTel. The blood spontaneously cleared and the left visual acuity gradually improved to 20/25 by 4 months. Fluorescein angiography confirmed MacTel, and once the hemorrhage resolved, both inner and outer retinal cavitation was identified on OCT of the left macula. The left best-corrected visual acuity remained at 20/25 at 2-year follow-up. Conclusion: Spontaneous resorption of hemorrhage was accompanied by visual improvement.

The authors present a case of morphologic changes of drusen and drusenoid pigment epithelial detachment (DPED) after treating choroidal neovascularization (CNV) using ranibizumab in age-related macular degeneration (AMD). A 71-year-old woman has noticed mild visual acuity deterioration in the right eye for several months. She was presented with some drusen and DPED associated with CNV. This patient was given intravitreal injection of 0.5 mg of ranibizumab five times at monthly intervals for treating CNV. DPED in the temporal and drusen in the superior to macula were diminished, which continued up to 2 months. Intravitreal ranibizumab injection may have influenced with diminishment of drusen and DPED. After 2 months, CNV was recurred.
