Case Reports in Ophthalmology最新文献

Introduction: Conjunctival cysts are usually asymptomatic but they can cause foreign body sensation and contribute to dry eye disease. The purpose of this case report is to describe the presentation and treatment of an infected inclusion cyst of a conjunctival nevus in a healthy 36-year-old patient.

Case presentation: A healthy 36-year-old man presented to the emergency department for redness and pain in his left eye for 1 day. Slit-lamp examination revealed a conjunctival hyperemia and a conjunctival nevus with 4 inclusion cysts, one of which was filled with purulent material. Fluorescein staining of the conjunctival epithelium was negative. Α mini-incision of the white cyst was performed using a 30 G needle, followed by bimanual drainage and topical treatment with tobramycin and moxifloxacin drops every 3 h for a week. A swab of the purulent drainage was positive for gram-positive flora. One week after the drainage of the cyst, the patient was asymptomatic and on slit-lamp examination, the 4 inclusion cysts were filled with a transparent liquid, there was not any vessel dilation and fluorescein staining was negative.

Conclusion: Conjunctival inclusion cysts, although considered benign, can become infected and form a conjunctival abscess. A mini-incision on the slit lamp combined with bimanual drainage and followed by topical antibiotic drops seems to be a safe and effective treatment.

Introduction: Sturge-Weber syndrome, a congenital vascular disorder, is associated with diffuse choroidal hemangiomas in which the current mainstay of treatment is radiation therapy, including external beam radiation therapy (EBRT). The purpose of this case report was to present a novel combination of treatments for diffuse choroidal hemangioma.

Case presentation: A 37-year-old man with a history of Sturge-Weber-associated glaucoma presented with an acute-onset decrease in vision in the right eye. Best-corrected visual acuity (BCVA) at the presentation was 20/400 in the right eye. Examination revealed a total macula-off, bullous, folded exudative retinal detachment and findings consistent with diffuse choroidal hemangioma. The patient was treated with a single injection of intravitreal anti-vascular endothelial growth factor (anti-VEGF) agent bevacizumab and 10 fractions of EBRT of the right eye. Follow-up examination at 17 months demonstrated complete resolution of subretinal fluid and no evidence of choroidal elevation on B-scan. Final BCVA in the right eye was 20/1,000.

Conclusion: This case uses simultaneous treatment with EBRT and bevacizumab in the treatment of diffuse choroidal hemangioma and associated exudative retinal detachment. Clinicians may use anti-VEGF agents early in the course of the disease in determining whether they may assist in preventing visual decline.

Introduction: A simple orbital lymphatic malformation usually presents with acute proptosis with ophthalmoplegia after an upper respiratory tract infection. Various treatments have been described but the lesions often recur after treatment due to their infiltrative nature.

Case presentations: A 6-year-old girl presented with a 5 × 10 mm translucent mass in the left inferior fornix for 3 years but she denied diplopia and visual disturbance. Orbital computed tomography with contrast emphasized the clinical findings, a nonseptated cystic lesion without enhancement in the anterior orbit. The lesion was surgically totally excised. Histopathological findings revealed an endothelial lining cyst without intraluminal cells consistent with a lymphatic malformation. In a 1-year follow-up, the lesion does not recur.

Conclusion: The simple orbital lymphatic malformation can present as a single nonseptate cystic lesion. Pathological study should be done for the definitive diagnosis. Surgical excision can achieve a favorable outcome.

Introduction: Dyskeratosis congenita is a rare genetic disorder characterized by abnormalities of the skin, nails, and oral mucosa. Retinal involvement in this condition is uncommon. Here, we present a case of a young male patient diagnosed with presumptive cytomegalovirus retinitis, ultimately found to be concomitant with dyskeratosis congenita.

Case presentation: A non-HIV-infected young male with recurrent infections, including aspergillus pneumonia and pneumocystis pneumonia, presented with presumptive cytomegalovirus retinitis in both eyes. Systemic manifestations included cutaneous hyperpigmentation, nail dystrophy, and oral mucosal leukoplakia. Genetic testing revealed a mutation in the DKC1 gene. The final diagnosis was dyskeratosis congenita complicated by presumptive cytomegalovirus retinitis.

Conclusion: Cytomegalovirus retinitis can serve as an ocular complication of dyskeratosis congenita. When a patient presents with cytomegalovirus retinitis, a comprehensive systematic examination should be conducted as it indicates severe immunodeficiency.

Introduction: Amphetamine-based medications such as Adderall^®, used for the treatment of attention deficit-hyperactivity disorder (ADHD), may theoretically elicit angle closure through their adrenergic mechanisms. The relationship between the use of implantable collamer lenses (ICLs) and angle closure has been extensively investigated based on appropriate vault and lens sizing and postoperative changes in the anterior chamber angle (ACA) and corneal morphology. This case reflects a synergistic impact from both Adderall^® use and ICL implantation for the proposed mechanism of angle closure.

Case presentation: A 36-year-old myopic female with ADHD controlled with Adderall^® underwent toric ICL implantation in the right eye after undergoing preoperative laser peripheral iridotomy. Shortly after, the patient developed episodic angle closure in the right eye, with episodes mainly occurring after taking an additional dose of Adderall^® in a dimly lit environment. The patient later had an ICL exchange with a smaller sized EVO+ toric ICL in the right eye and remained asymptomatic after.

Conclusion: Additive mechanisms from both the ICL and Adderall^® were present in our patient. The ICL caused crowding of the ACA through a pseudophacomorphic mechanism, and the Adderall^® caused increased iridotrabecular contact secondary to pharmacologic mydriasis. This resulted in episodic angle closure with subsequent spikes in the intraocular pressure. There are no current reports or studies in the current literature describing the combined mechanisms of ICL implantation and Adderall^® use in the potential development of angle closure. Further studies may be done to assess interactions of such medications in patients after ICL implantation.

Introduction: Syphilis exhibits a wide range of clinical presentations, mimicking various systemic and ocular diseases. Ocular syphilis, in particular, manifests with multiple presentations, ranging from anterior uveitis to panuveitis, making it a potential differential diagnosis for Behçet's uveitis. Here, we present a unique case of Behçet's panuveitis that was undergoing immunomodulatory therapy and was complicated by ocular syphilis. Notably, this case also featured rare cutaneous manifestations associated with secondary syphilis, commonly known as malignant syphilis.

Case presentation: A 38-year-old Thai man with refractory end-stage Behçet's panuveitis reported a maculopapular rash accompanied by increased intraocular inflammation. The escalation of immunomodulatory therapy, intended to manage the provisional diagnosis of active ocular and cutaneous Behçet's disease, resulted in clinical deterioration, with the rash transforming into multiple noduloulcerative lesions. Despite negative serologic tests for syphilis at baseline before initiating immunomodulatory therapy, syphilis infection was eventually diagnosed following reevaluation and the observation of spirochetes in a skin biopsy specimen. The patient was treated with intravenous penicillin G, resulting in an improvement in intraocular inflammation and resolution of noduloulcerative rashes.

Conclusion: Intraocular inflammation and mucocutaneous lesions in syphilis can mimic the presentation of Behçet's disease. The introduction of immunomodulatory therapy may alter the clinical picture, leading to a severe and atypical presentation. A high index of suspicion for reevaluating serologic tests or performing tissue biopsies is warranted for an accurate diagnosis.

Introduction: Combined nutritional deficiency is an uncommon cause of vision loss in the USA. Notably, vitamin A deficiency can produce nyctalopia but rarely causes bilateral central vision loss. The combination of these symptoms is unusual, although likely underreported.

Case presentation: We report an exceptionally rare case of bilateral central vision loss and nyctalopia caused by combined vitamin A, zinc, and copper deficiency, likely following bariatric surgery and alcohol use. Following mineral and vitamin supplementation, the patient's vision improved significantly and returned to baseline within 1 month. Vision loss resulting from this specific multicombination of vitamin and mineral deficiency has never been reported previously in the English-language ophthalmic literature.

Conclusion: Given rising rates of bariatric surgery and alcohol use in the USA and abroad, clinicians should be aware that the combination of progressive nyctalopia and bilateral central vision loss may be produced by combined nutritional deficiency. Screening and supplementation of both vitamin and mineral deficiency may result in dramatic reversal of visual loss in such cases.

Introduction: Fluorescein angiography (FA) is a useful investigation in the diagnosis and treatment of retinal and choroidal disease. FA has well-reported adverse effects, most being mild. Very few cases have reported cutaneous venous staining following FA.

Case presentation: Two cases are reported. Case 1 was a 90-year-old female with bilateral neovascular age-related macular degeneration. In the few minutes following her routine FA, she developed cutaneous fluorescein staining ascending along the superficial forearm veins proximal to the cannula in situ at the dorsal wrist. Case 2 was a 50-year-old male with diabetic macular oedema. In the minutes following his FA, he developed cutaneous fluorescein staining descending along the dorsal forearm veins distal to the cannula in situ at the cubital fossa. Both patients were managed conservatively with the stain resolving in the next few days.

Conclusion: Cutaneous fluorescein staining around superficial vasculature is a rare phenomenon. Despite this, it seems to be self-limiting and does not require any treatment.

Introduction: Iris retraction syndrome (IRS) is a rare clinical condition characterized by a backbowing of the iris positioned on the lens with a complete pupillary block. Immune checkpoint inhibitors (ICIs) are a new class of immunomodulating agents used in cancer therapy, and although they have high response rates, ophthalmic-related side effects have been reported. We report a rare case of bilateral IRS with hypotony after therapy with nivolumab.

Case presentation: We present a case of bilateral IRS with hypotony, 3 mm Hg OD and 5 mm Hg OS, after therapy with nivolumab. The patient presented with decreased vision, corneal edema, keratic precipitates, deep anterior chamber with posterior synechiae, and hypotony maculopathy. Anterior segment OCT revealed a sharp posterior displacement of the iridolenticular diaphragm consistent with IRS. Discontinuation of nivolumab until ocular improvement was suggested, following oncologic consultation. Four months later, the patient exhibited iris bombé with angle closure and increased IOP. This was managed with phacoemulsification and concomitant surgical iridectomy. One month after surgery, the patient's IOP had returned to physiologic values, and the iris configuration had returned to normal.

Conclusion: The exact mechanism of IRS remains unclear, but it is suggested that an aqueous imbalance, in conjunction with uveitis and hypotony, creates an anterio-posterior movement of the iridolenticular diaphragm when the pupillary block is present. Our case highlights the importance of monitoring patients receiving ICIs for ophthalmic adverse effects and prompt management to prevent permanent visual damage. In conclusion, this is the first reported case of IRS after therapy with ICIs. Further research is needed to fully understand the exact mechanism by which it is induced.

Introduction: We aimed to describe a case of bilateral keratoconjunctivitis after exposure to the toxic sap of Euphorbia lathyris.

Case report: A 76-year-old gentleman presented after exposure to E. lathyris whilst he was gardening. He had 6/12 visual acuity in his right eye, and 6/4 in his left. Examination revealed marked periocular dermatitis, conjunctival injection and corneal oedema in the right eye with diffuse punctate epithelial staining. He was treated with ocular irrigation, topical steroids, antibiotics, cycloplegics and lubricants. Over 48 h, his left eye started to become symptomatic. He developed bilateral corneal epithelial defects and anterior chamber inflammation. His visual acuity worsened to 6/36 right and 6/24 left. At his 3-week follow-up, there was marked improvement in the resolution of the toxic keratoconjunctivitis in both eyes.

Conclusion: Toxic sap from E. lathyris can cause severe keratoconjunctivitis. Irrigation of both eyes despite unilateral symptoms and early follow-up should be considered signs of toxicity may only become evident after 24-48 h.
