  • Outcomes of Vitrectomy for Retinal Detachment in a Patient with Ehlers
    Lumi et al. J Med Case Reports (2021) 15:249 https://doi.org/10.1186/s13256-021-02855-w CASE REPORT Open Access Outcomes of vitrectomy for retinal detachment in a patient with Ehlers–Danlos syndrome type IV: a case report Xhevat Lumi1*, Gaber Bergant2, Anila Lumi1 and Mina Mahnic1 Abstract Background: The Ehlers–Danlos syndrome (EDS) is a group of connective tissue disorders characterized by fragile blood vessels and an increased tendency for bleeding and scarring. Here, we report the outcome of a pars plana vitrectomy for the treatment of rhegmatogenous retinal detachment in a patient with EDS type IV (vascular type). Case presentation: A 40-year-old Slovenian man with high myopia, unilateral bullous retinal detachment, and vitre- ous hemorrhage was referred for surgery. The patient had a history of colon perforation, muscle and arterial rupture in both lower limbs, and recurrent shoulder joint luxations. Genetic testing revealed a pathogenic mutation in the COL3A1 gene. The patient underwent a 25-gauge three-port pars plana vitrectomy. The tendency for bleeding during surgery was prevented by endodiathermy applied to the edges of the retinal breaks. Endolaser photocoagulation was performed under air. The surgical procedure was completed with the injection of gas tamponade, followed by the patient remaining for a few days in a face-down position. Mild postoperative vitreous hemorrhage was resorbed in frst week after the surgery. Postoperative extensive pigment dispersion on the posterior lens face persisted for several weeks. After the gas tamponade had resorbed, the retina was fat and remained attached during the follow-up period.

Email: [email protected] ……………………………………………………………………………………………………………………………………... Abstract Background: Dacryocystitis is an infection and inflammation of the lacrimal sac and most common cause of ocular morbidity in India. It’s accounting for 87.1% of epiphora and causes social discomfort due to continuous watering from the eyes. It is more common in India as being tropical country. It has higher incidence among lower socioeconomic status. Hygiene plays an important role in its aetiology. Objective: This study was aimed to survey the demographic characteristics of patients received external dacryocystorhinostomy (DCR) surgery to correlate with religious aspect of the patients. Material & Methods : The present study is a retrospective study conducted at Ophthalmology Department from the hospital records of patients who underwent external DCR for epiphora from January 2013 to December 2017. Results: Out of 305 cases underwent DCR (n=305), maximum (n=179, 58.69%) were above the age of 40 years out of which maximum were in age group of 41-50 years (n=78, 24.57%), majority of them were females 70.49% (n=215) with males being only 29.51% (n=90).

  • Acquired Etiologies of Lacrimal System Obstructions
    5 Acquired Etiologies of Lacrimal System Obstructions Daniel P. Schaefer Acquired obstructions of the lacrimal excretory outfl ow system will produce the symptoms of epiphora, mucopurulent discharge, pain, dacryocystitis, and even cellulitis, prompting the patient to seek the ophthalmologist for evaluation and treatment. Impaired tear outfl ow may be functional, structural, or both. The causes may be primary – those resulting from infl ammation of unknown causes that lead to occlusive fi brosis—or secondary, resulting from infections, infl amma- tion, trauma, malignancies, toxicity, or mechanical causes. Secondary acquired dacryostenosis and obstruction may result from many causes, both common and obscure. Occasionally, the precise pathogenesis of nasolacrimal duct obstruction will, despite years of investigations, be elusive. To properly evaluate and appropriately treat the patient, the ophthal- mologist must have knowledge and comprehension of the lacrimal anatomy, the lacrimal apparatus, pathophysiology, ocular and nasal relationships, ophthalmic and systemic disease process, as well as the topical and systemic medications that can affect the nasolacrimal duct system. One must be able to assess if the cause is secondary to outfl ow anomalies, hypersecretion or refl ex secretion, pseudoepiphora, eyelid malposition abnormalities, trichiasis, foreign bodies and conjunctival concretions, keratitis, tear fi lm defi ciencies or instability, dry eye syn- dromes, ocular surface abnormalities, irritation or tumors affecting the trigeminal nerve, allergy, medications, or environmental factors. Abnormalities of the lacrimal pump function can result from involu- tional changes, eyelid laxity, facial nerve paralysis, or fl oppy eyelid syndrome, all of which displace the punctum from the lacrimal lake. If the cause is secondary to obstruction of the nasolacrimal duct system, the ophthalmologist must be able to determine where the anomaly is and what the cause is, in order to provide the best treatment possible for the patient.
