RESUMO
This review covers the utility of electrophysiological studies relevant to inflammatory diseases of the retina in conditions such as acute posterior multifocal placoid pigment epitheliopathy, acute zonal occult outer retinopathy, Adamantiades-Behçet disease, autoimmune retinopathy and neuro-retinopathy, birdshot chorioretinopathy, multiple evanescent white dot syndrome, and Vogt-Koyanagi-Harada disease. Electrophysiological studies can help with the diagnosis, prognostication, evaluation of treatment effects, and follow-up for these conditions.
RESUMO
Purpose: To examine an underreported and underdiagnosed phenomenon with implications for the pathophysiological mechanisms of tattoo-induced uveitis. Methods: Two cases highlighting the clinical presentation of tattoo-related uveitis were evaluated. Results: A 28-year-old man with biopsy-proven sarcoidosis and ocular manifestations presented with worsening retinal vasculitis after acquiring a red-ink tattoo. Each subsequent flare followed acquisition of a new tattoo. A 31-year-old woman without systemic sarcoidosis presented with multiple episodes of bilateral intermediate uveitis and macular edema concurrent with inflammatory granulomas to recently acquired black-ink tattoos. A skin biopsy in both patients showed cutaneous noncaseating granulomas. Conclusions: These cases add to those reported in the literature and emphasize the importance of understanding the modifiable factors of inflammatory ocular disease. Future study is necessary to understand the mechanisms of tattoo-related uveitis.

RESUMO
It is important for clinicians to consider exposure to toxic substances and nutritional deficiencies when diagnosing and managing cases of vision loss. In these cases, physiologic damage can alter the function of key components of the visual pathway before morphologic changes can be detected by traditional imaging methods. Electrophysiologic tests can aid in the early detection of such functional changes to visual pathway components, including the retina or optic nerve. This review provides an overview of various electrophysiologic techniques, including multifocal electroretinogram (mfERG), full-field ERG (ffERG), electrooculogram (EOG), pattern electroretinogram (PERG), and visual evoked potential (VEP) in monitoring the retinal and optic nerve toxicities of alcohol, amiodarone, cefuroxime, cisplatin, deferoxamine, digoxin, ethambutol, hydroxychloroquine, isotretinoin, ocular siderosis, pentosane, PDE5 inhibitors, phenothiazines (chlorpromazine and thioridazine), quinine, tamoxifen, topiramate, vigabatrin, and vitamin A deficiency.

PURPOSE: To report on a case of successful treatment of intraocular inflammation (IOI) secondary to brolucizumab intravitreal injection that responded to a single sub-Tenon injection of triamcinolone. OBSERVATIONS: An 81-year-old female with a longstanding history of exudative age-related macular degeneration (AMD) was unresponsive to various regimens of anti-VEGF injections. Her AMD was treated with one intravitreal injection of brolucizumab (6mg/0.05ml) into the right eye. On a follow-up visit, she had a new-onset conjunctival injection, with anterior chamber and vitreous inflammation, in the right eye, which was diagnosed as non-granulomatous iridocyclitis. The patient was treated with one posterior sub-Tenon injection of triamcinolone (40mg/ml) into the right eye. Subsequently, there was a durable resolution of inflammation, and her vision improved along with the resolution of her exudation. CONCLUSIONS AND IMPORTANCE: This case suggests that some brolucizumab-related IOI episodes may be treated with posterior sub-Tenon triamcinolone. Further studies may serve to elucidate the role of sub-Tenon triamcinolone in brolucizumab-associated IOI.
RESUMO
OBJECTIVE: We conducted a systematic review to evaluate the outcome of macular hole (MH) treatment in eyes with uveitis. DATA SOURCE: We searched PubMed and Embase databases from inception through August 15, 2021. STUDY SELECTION: We included eyes with MHs secondary to uveitis that were managed medically or underwent pars plana vitrectomy (PPV). We excluded eyes with idiopathic MH and those secondary to causes other than uveitis. RESULTS: Of 27 articles, we identified 86 eyes with MH secondary to uveitis that received either conservative medical treatment alone or PPV with adequate follow-up. The mean (± SD) age of patients included in this review was 46.6 (± 16.8) years; 60.5% were males. The most common etiology of uveitis was Behçet's disease (34.6%) and toxoplasmosis (19.7%). The most common anatomical location of uveitis was posterior (59.3%) followed by panuveitis (35.2%). The mean (± SD) baseline LogMAR vision was 1.1 (± 0.5). Conservative medical treatment was employed in 34.9%, while PPV was performed in 65.1% of eyes. Overall, the mean (SD) LogMAR vision improved from 1.1 (± 0.5) at baseline to 0.7 (± 0.5) after treatment. Inflammation-related MHs were closed in 40% of eyes after conservative therapy and in 87.5% of eyes after PPV. Visual improvement occurred in most eyes (83.9%) that had successful closure of their MH. CONCLUSIONS: Visual improvement occurs in most eyes that had successful closure of their inflammation-related MH. Conservative medical control of uveitis may lead to closure of inflammation-related MHs and is an important step prior to surgery, if required. Surgical intervention for inflammation-related MHs is associated with good functional and anatomical results.

PURPOSE: To report on a case of reactivation of acute retinal necrosis following SARS-CoV-2 infection. METHODS: Observational case report. Observations. A 32-year-old female with a distant history of left retinal detachment secondary to necrotizing herpetic retinitis complained of right-eye vision loss, pain, redness, and photophobia. An ophthalmological examination revealed findings consistent with acute retinal necrosis of the right eye. A polymerase chain reaction (PCR) analysis of the right vitreous was positive for herpes simplex virus type 2 (HSV-2). A coronavirus disease 2019 (COVID-19) screening test using reverse transcriptase- (RT-) PCR was positive for SARS-CoV-2 RNA. CONCLUSIONS: Our case suggests that COVID-19 may cause a latent HSV infection to reactivate, causing contralateral involvement in patients with a prior history of HSV-associated acute retinal necrosis.
RESUMO
BACKGROUND: Hodgkin lymphoma (HL) is a hematopoietic neoplasm characterized by cancerous Reed-Sternberg cells. In contrast to ophthalmic manifestations by non-HL that are well recognized, there is paucity of the literature as it relates to ophthalmic manifestation by HL. We performed a comprehensive review of published studies (case reports and small case series) to characterize the ophthalmic manifestations of HL. SUMMARY: Thirty patients were identified with ophthalmic manifestation of HL. Thirteen (43%) were male, and 14 (46%) were female (in 3 cases, sex was not specified). The median age at ophthalmic presentation was 27 years. Diagnosis of HL was made after ophthalmic manifestation in 10 (33%) cases, whereas 11 (36%) cases had a prior diagnosis of HL. Ophthalmic manifestations can be classified into 3 main groups; direct infiltration, inflammatory reaction, and paraneoplastic process. Seven cases had infiltration of the optic nerve. Uveal inflammatory reaction was reported in 21 cases. The presence of intraocular Reed-Sternberg cells had been confirmed in 1 case with granulomatous uveitis. Conjunctival and corneal reaction was seen in 3 cases. HL was in stage 2 or higher, with only 1 case with stage 1A (12 cases HL stage not specified). Seven cases (22%) died of HD, all were diagnosed with advanced lymphoma, and none was treated with chemotherapy. KEY MESSAGE: Ocular involvement in HL is extremely rare. A few cases of histopathologically confirmed optic nerve/tract infiltration are within the spectrum of CNS involvement by HL. Inflammatory uveitis is the most common ophthalmic association of HL. In the presence of prior known diagnosis of HL, restaging should be considered to exclude recurrence. Toxicity or adverse reaction to drugs used to treat HL may also contribute to ophthalmic involvement.
RESUMO
Photopigment bleaching occurs with saturation of photoreceptor pigment by short-wavelength fundus autofluorescence imaging. This phenomenon is seen as characteristic hyperautofluorescence with subsequent imaging acquisition. Herein, a patient with multiple sclerosis was found to exhibit increased choroidal hyperfluorescence during fluorescein angiography (FA) that corresponded with a circumscribed area of intense blue light exposure during initial scanning laser ophthalmoscopy. To the authors' knowledge, this case is the first description of photobleaching phenomenon during FA and should be recognized as nonpathologic by the clinician.

PURPOSE: Evaluate a single suprachoroidal injection of a proprietary triamcinolone acetonide suspension, CLS-TA, in subjects with macular edema due to noninfectious uveitis. METHODS: Randomized, controlled, masked Phase 2 study. Safety and efficacy of a single suprachoroidal injection of CLS-TA (4.0 and 0.8 mg in a 4:1 ratio) were assessed at 1 and 2 months after injection. The primary efficacy endpoint was change in central subfield thickness from baseline to Month 2, assessed by spectral domain optical coherence tomography. RESULTS: Twenty-two adults were enrolled. The primary endpoint was met in subjects who received suprachoroidal injection of CLS-TA 4.0 mg, mean central subfield thickness significantly decreased from baseline by 135 µm and 164 µm at Month 1 (P = 0.0056) and Month 2 (P = 0.0017), respectively. At Month 2, 69% of subjects who received 4.0 mg experienced ≥20% reduction in central subfield thickness, and 65% had improvement of best-corrected visual acuity of ≥5 Early Treatment Diabetic Retinopathy Study letters, with a mean improvement of 9.2 letters (P = 0.0004). Safety analyses supported acceptable safety/tolerability, with no corticosteroid-related increases in intraocular pressure. CONCLUSION: A single suprachoroidal injection of CLS-TA (4.0 mg; 0.1 mL) in subjects with macular edema due to noninfectious uveitis was well-tolerated, significantly reduced central subfield thickness from baseline at 2 months, and significantly improved visual acuity.

PURPOSE: The purpose of this article is to describe a novel surgical technique for the management of large suprachoroidal hemorrhages associated with the insertion of glaucoma seton devices. METHODS: In this interventional case series, the authors describe six eyes of six patients who had management of suprachoroidal hemorrhage with pars plana choroidal drainage along with simultaneous insertion of viscoelastic into the posterior segment. All patients had a median of 8-month postoperative follow-up. RESULTS: Five of the 6 patients had useful final vision ranging from 20/40 to 20/200. In all cases, the postoperative intraocular pressures did not increase beyond 28 mmHg and responded to aqueous humor suppressants. CONCLUSION: As suprachoroidal hemorrhage can be a devastating complication of glaucoma surgery, the authors report a relatively straightforward surgical technique that can restore ambulatory vision in a high proportion of patients.

PURPOSE: Macular pathology, including macular holes (MHs), epiretinal membranes (ERMs), and macular edema, is a cause of irreversible vision loss in the setting of uveitis. Medical management involves corticosteroids, immunomodulatory medications, and biologics to control inflammation. Pars plana vitrectomy (PPV) has been suggested as a therapy for uveitis, with reports of reduced inflammation and decreased dependence on medication postoperatively. Currently, PPV is reserved for retinal detachments, vitreous opacities, and ERMs, causing vitreomacular traction. However, little is known about the visual outcomes of PPV with ERM peel for MH, or in ERM without evidence of traction in the context of uveitis. METHODS: Review of small case series and case reports support both conservative medical treatment and vitrectomy, independently, and in combination, in the management of macular pathology in the setting of uveitis. RESULTS AND CONCLUSIONS: Further studies are required to study uveitic etiologies separately with respect to visual outcomes after vitreoretinal surgery and medical management.

BACKGROUND: To describe a patient who presented with bilateral serous retinal detachments without the other retinal vascular or ocular inflammatory signs, and who was ultimately diagnosed with acute leukemia. METHODS: Case report and review of the literature. RESULTS: This patient presented with isolated bilateral serous retinal detachments as the initial manifestation of hematologic malignancy. CONCLUSION: Acute leukemia may present with serous retinal detachments without the signs of other retinopathy or ocular inflammation. Incorrect diagnosis may delay detection and proper management of the malignancy. Leukemia should be considered in the differential diagnosis of isolated serous retinal detachments.
