Susac syndrome (SS) is a rare disease affecting the microvasculature of the inner ear, brain, and retina, which usually presents with the triad of hearing loss, encephalopathy, and branch retinal artery occlusions. This condition usually affects young women and treatment consists, in most cases, of immunosuppression. In this article, we report the case of a 35-year-old female patient with an incomplete SS, with visual and hearing manifestations.

Tubulointerstitial nephritis and uveitis syndrome is an uncommon clinical entity. Usually, renal involvement is moderate, and uveitis is acute, bilateral, anterior, and nongranulomatous (revised). We present the case of a 55-year-old female patient who went to the emergency department with complaints of asthenia, myalgia, and paresthesia. One week later, she complained of photophobia and was diagnosed with bilateral nongranulomatous acute anterior uveitis. The next day, due to hypotension and acute kidney injury, the patient was hospitalized. Renal biopsy showed tubulointerstitial nephritis. The patient was started on oral prednisolone, achieving uveitis resolution and renal function stability. After slow corticoid reduction, the patient presented uveitis recurrence complicated with bilateral optic disc (revised) edema and cystoid macular edema (CME) in the left eye. After oral prednisolone reduction, the patient suffered another relapse with CME worsening. We decided to initiate methotrexate 7.5 mg/week, achieving ocular and renal function stability.

Purpose: The purpose of the study was to evaluate the contribution of orbital biopsy for the management of patients with an orbital mass of unknown etiology using the Greenwich Grading System (GGS). Methods: This was a retrospective case series conducted at a tertiary hospital over a period of 10 years (2007–2017). Case records of all patients with an orbital mass were reviewed. All relevant data collected from the medical records electronic database were analyzed. The GGS was used to assess the contribution of orbital biopsy for the diagnosis, investigation, and treatment of each patient. Results: Ninety-two medical records were reviewed; 34 patients underwent orbital biopsy. The mean age was 53 ± 26 years and 58.7% were female. In the biopsied group, the most common histopathological diagnoses were lymphoma (44.1%), nonspecific orbital inflammation (14.4%), and squamous cell carcinoma (8.8%). After the biopsy, a new diagnosis was obtained in 41.2%, although in most patients (58.8%), the biopsy confirmed the suspected diagnosis. Regarding the therapeutic management, 32.4% started a new treatment, 29.4% did not change their treatment, 32.4% altered/stopped their treatment, and 5.9% allowed reassurance and explanation for the patients. Conclusions: Orbital biopsy was considered a valuable investigation for the management of patients with an orbital mass of unknown etiology. In most cases (58.8%), the result of the biopsy confirmed the suspected diagnosis, and in around 41.2%, a new diagnosis was made. Most of the patients (64.8%) changed their treatment or started a new one based on the histopathological result.

We present the case report of a 6-year-old girl with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis associated with bilateral optic neuritis. She initially presented with disturbing behaviors and gait impairments and was hospitalized in the context of meningoencephalitis, without agent isolation and with inconclusive laboratory tests. After discharge, she noted a loss of vision with impaired color sensation and returned to the emergency department. Her best-corrected visual acuity was 20/400 in both eyes, and fundoscopy revealed bilateral optic disc edema. She was hospitalized once again. Anti-NMDAR antibodies were detected in serum and cerebrospinal fluid. The patient was successfully treated with a pulse of methylprednisolone, followed by a tapering regimen of prednisolone. She recovered to 20/20 vision in the right eye and left eye. Our report highlights additional aspects of anti-NMDAR encephalitis in children and suggests that the disease could present atypical visual manifestations, which requires multidisciplinary approaches.

The two immunosuppressants most used topically in ophthalmology are cyclosporine (CS) and tacrolimus (TL). Their mechanism of action is similar, but the TL is ten to a hundred times more powerful than the CS. We reviewed the studies found in the literature on the use of topical TL and described them, as follows, divided by indication of use. Topical TL is effective and safe against inflammatory and immunological processes of the ocular surface, although it is less powerful than corticosteroids, it has fewer side effects.

Purpose: The purpose of this study is to present a novel method of capturing and viewing stereoscopic ophthalmological pictures using the inexpensive smartphone technology applied to a common slit lamp. To assess the best perceived method for viewing this images when reconstructed. Methods: We adapted two smartphones using a fixation device for each slit-lamp ocular. By obtaining simultaneous images of each ocular, we reconstructed them in different formats. Images from a trabeculectomy bullae, corneal transplant, and glaucomatous optic nerve (GON) were rated by five independent ophthalmologists in terms of perceived image quality from 1 to 5. Results: All of the images obtained were three dimensional and of very good quality (grading 4.04 ± 0.84) in a scale from 1 to 5. Parallel-eyed images were graded with a mean of 4.5 ± 0.5, and anaglyph images were graded 3.58 ± 0.86, which was statistically lower than for parallel-eyed format (P = 0.002). Mean image quality was lower for the optic nerve and higher for the penetrating keratoplasty (PK) image, but grades did not differ significantly for the three different pictures (bullae vs. PK P = 0.18; PK vs. GON P = 0.07; bullae vs. GON P = 0.59). Conclusions: It is possible to obtain the quality stereoscopic images by combining the smartphone technology and fixation devices.

Purpose: The purpose is to identify the various causes of ocular disease and surgical interventions undertaken in children (0–18 years of age) seen during an annual ophthalmic surgical trip to Belize. Methods: A retrospective, cross-sectional review of records from seven annual surgical trips conducted by the World Pediatric Project providing pediatric ophthalmologic clinical and surgical care to Belize from 2013 to 2019 was performed. Results: The charts of 313 patients who received care during the surgical mission trips were examined. From these 313 patients, there were 545 independent clinical encounters, yielding 405 diagnoses. Patients aged 6–10 years were most commonly seen (32.1%) followed by those 2–5 years old (28.1%). The most common pathophysiology seen was strabismus/ocular motility disorder (151 diagnoses; 37.4%), followed by refractive issues (69 diagnoses; 17.1%), eyelids and/or lacrimal system disorders (53 diagnoses; 13.1%), disorders of the retina/vitreous (30 diagnoses; 7.4%), lens abnormalities/cataract (28 diagnoses; 6.9%), amblyopia (23 diagnoses; 5.7%), disorders of the cornea/conjunctiva (23 diagnoses; 5.7%), trauma (13 cases; 3.2%), conditions affecting the globe/orbit (7 diagnoses; 1.7%), other (6 diagnoses; 1.5%), and glaucoma (1 diagnoses, 0.2%). Conclusion: This study identified the most frequently diagnosed ocular conditions encountered during annual surgical mission trips to Belize. The most prevalent pathophysiology encountered was strabismus/ocular motility disorders, followed by refractive issues. The most common refractive issues encountered were myopia and astigmatism. This is the first study detailing pediatric ocular disease in Belize.

Background: Medical ministry international (MMI) is a Canadian charitable organization that coordinates healthcare missions to underserved people in developing countries. Objective: We report on the baseline clinical findings of a mission trip to Ciénaga de Oro, Colombia, present the methods used in the mission and the efforts to establish a local eye care service with long-term sustainability. Methods: Data were collected on patients seen during a 2-week mission trip from January 13 to 24, 2020. Data included eye health and the services given. Results: Altogether 5529 patients were seen by the team. Nearly 247 surgeries were performed by ophthalmologists. The most common diagnosis performed was a refractive error, for which 4066 patients (74%) received eyeglasses. Another 835 (15%) had a consultation by an ophthalmologist, of which 260 (5%) received surgery, mostly manual small incision cataract surgery and intraocular lens insertion. Conclusions and Importance: MMI is helping to reduce the prevalence of preventable blindness in the Ciénaga de Oro population; however, further training to increase the capacity of local ophthalmic services is required to improve long-term eye care to the community.
