Central vision loss, photopsia, floaters, and macular edema in a highly myopic patient can easily be misinterpreted as high myopia complications. In atypical cases, detailed examination and a thorough diagnostic workup are required to establish the proper diagnosis, which is often beyond the scope of diagnoses initially considered.

BACKGROUND
The majority of antidepressants inhibit serotonin reuptake and include the selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and the serotonin reuptake inhibiting tricyclic antidepressants.
OBJECTIVE
The objective of this study was to investigate and describe the range and impact of reported adverse visual effects linked to serotonin reuptake inhibiting antidepressants.
METHODS
Using data from a global database of patient spontaneous reports of drug adverse events, we systematically identified eligible reports of visual problems linked to the use of serotonin reuptake inhibiting antidepressants. We analyzed these data using simple descriptive statistics to present the range and impact.
RESULTS
We identified 124 reports of visual problems. Reports originate from 18 countries and involve 11 different drugs. The most commonly reported symptoms were vision blurred/visual acuity reduced (n = 79, 63.7%), night blindness (n = 22, 17.7%), vitreous floaters (n = 21, 16.9%), photophobia (n = 19, 15.3%), diplopia (n = 15, 12.1%), palinopsia (n = 13, 10.5%), visual field defect (n = 12, 9.7%), photopsia (n = 11, 8.9%) and visual snow syndrome (n = 11, 8.9%). 74 patients indicated that the side effect was bad enough to affect everyday activities, 62 had sought health care, and 50 indicated that their work had been affected. 49 patients reported an enduring vision problem after discontinuation of treatment.
CONCLUSIONS
The data suggest that serotonin reuptake inhibiting antidepressants can produce a range of adverse effects on vision that in some cases can be long-lasting after discontinuation of the drug. Further efforts are needed to understand the mechanisms involved, the incidence among those prescribed these medications, and identify any risk or mitigation factors.

PURPOSE
To describe a patient who developed concurrent acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and posterior scleritis.
OBSERVATIONS
We describe a middle-aged woman that developed eye pain and photopsia. She was found to have a "T-sign" on ultrasound of the right eye and multiple, nearly confluent, ill-defined subretinal whitish lesions in both eyes. After an extensive laboratory evaluation and neuroimaging, her photopsia, pain with eye movements, and subretinal lesions began to regress on high dose systemic corticosteroids.
CONCLUSIONS AND IMPORTANCE
This is the first reported case of bilateral APMPPE and concurrent posterior scleritis. Our case highlights the importance of performing a full review of systems, specifically eliciting neurological changes, and dilated eye examination in all new uveitis cases.

BACKGROUND AND AIM
AZOOR is a rare disease characterized by loss of zones of outer retinal function, first described by J Donald Gass in 1993. Symptoms include acute onset photopsias and subjective visual field losses. The syndrome is characterized by a normal fundus appearance, scotomas and electroretinographic changes pointing towards outer retinal dysfunction. Evolution, response to immunosuppressive treatment and outcome are difficult to predict. The aim of this small case series was to identify the morphological changes and sequence of events in AZOOR thanks to multimodal imaging.
METHODS
Charts of AZOOR patients seen in the Centre for Ophthalmic Specialized care (COS, Lausanne, Switzerland) were analyzed by multimodal imaging including fundus photography, fluorescein angiography (FA), indocyanine green angiography (ICGA), blue light fundus autofluorescence (BL-FAF) and spectral domain optical coherence tomography (SD-OCT) in addition to a complete ophthalmological examination including visual field testing and microperimetry, as well as OCT angiography (OCT-A) and ganglion-cell complex analysis when available. Cases and Results: Three AZOOR patients with a mean follow-up of 47 ± 25.5 months were included following the clinical definitions laid down by J Donald Gass. The primary damage was identified at the level of the photoreceptor outer segments with an intact choriocapillaris and retinal pigment epithelium (RPE) layer, these structures being only secondarily involved with progression of the disease.
CONCLUSION
Although AZOOR has often been included within white dot syndromes, some of which are now known to be choriocapillaris diseases (choriocapillaritis entities), our findings clearly commend to differentiate AZOOR from entities such as MEWDS (Multiple evanescent white dot syndrome), APMPPE (Acute Posterior Multifocal Placoid Pigment Epitheliopathy), MFC (Multifocal Choroiditis) and others, as the damage to photoreceptors is primary in AZOOR (a retinopathy) and secondary in choriocapillaritis (a choriocapillaropathy).

Most primary sensory neurons (PSNs) generate a slowly-activating inward current in response to membrane hyperpolarization (I) and express HCN1 along with additional isoforms coding for hyperpolarization-activated channels (HCN). Changes in HCN expression may affect the excitability and firing patterns of PSNs, but retinal and inner ear PSNs do not fire action potentials, suggesting HCN channel roles may extend beyond excitability and cell firing control. In patients taking I blockers, photopsia triggered in response to abrupt changes in luminance correlates with impaired visual signal processing via parallel rod and cone pathways. Furthermore, in a mouse model of inherited retinal degeneration, HCN blockers or Hcn1 genetic ablation may worsen photoreceptors' demise. PSN's use of HCN channels to adjust either their firing rate or process signals generated by sensory transduction in non-spiking PSNs indicates HCN1 channels as a versatile tool with a novel role in sensory processing beyond firing control.

We report a case of morning glory disc anomaly in a young patient with tractional retinal detachment successfully repaired with complex pars plana vitrectomy, membrane peel, laser, and oil tamponade. A 19-year-old female with a history of right morning glory disc anomaly associated with PAX6 gene mutation presented with floaters, photopsia, central scotoma, and visual acuity (VA) of 1/200. A complex macula-involving tractional retinal detachment centered around the optic nerve with a morning glory disc anomaly. Retinal detachment was treated with 25-gauge pars plana vitrectomy with difficult separation of the posterior hyaloid. Fibrous preretinal membranes were peeled, a temporal relaxing retinotomy was required, subretinal fluid was drained through a superonasal retinotomy during air-fluid exchange, endolaser was applied, and tamponade was achieved with 1,000-centistoke silicone oil. The retina remained attached at 1-year follow-up, with VA count fingers throughout. Morning glory disc is a rare congenital anomaly associated with PAX6 gene mutation that most often occurs unilaterally. It is rarely associated with tractional retinal detachment. Optimization of visual outcome is imperative despite a poor visual prognosis.

Review
PURPOSE
This work presents a case of syphilitic outer retinopathy with findings similar to those of acute zonal occult outer retinopathy (AZOOR). We also discuss the clinical characteristics, treatment, and prognosis of this entity.
METHODS
A case report and systematic literature review are presented.
RESULTS
A 56-year-old woman presented with acute vision loss, localized photopsia, a central scotoma, and retinal findings that were all consistent with AZOOR. A further workup led to a diagnosis of syphilis. Oral prednisone and intravenous penicillin resulted in the resolution of the posterior uveitis and the restoration of visual acuity. However, the central scotoma remained at the 3-year follow-up visit.
CONCLUSIONS
Syphilitic outer retinopathy is a distinct entity characterized by the disruption of the ellipsoid zone visible on optical coherence tomography and a corresponding increase in fundus hyperautofluorescence in the affected areas. Although some patients may present with a demarcation line, as is seen with AZOOR, the fundus is oftentimes unremarkable or may show only subtle retinal pigment epithelium changes. Uveitis resolution and visual acuity restoration may be expected following treatment; however, visual field disturbances may persist.

Review
Spontaneous posterior vitreous detachment (PVD) is a common age-related condition in which prevalence tends to increase with age. Acute PVD can cause the onset of symptoms that include visual disturbances, myodesopsia and photopsia. The goal of this short review was to provide a quick glance at the important factors related to PVD based on current literature in this field, which includes incidence, symptoms, diagnosis, risk factors, and education for patients with acute symptoms, and treatments. The take home message is that an ophthalmic examination at the onset of symptoms is of utmost importance, considering that irreversible sight-threatening complications can be prevented if diagnosed and treated promptly.

European Journal of Ophthalmology Jan 2022The purpose of this study is to report a case of venous-air embolism during a vitrectomy for endoresection of choroidal melanoma.
INTRODUCTION
The purpose of this study is to report a case of venous-air embolism during a vitrectomy for endoresection of choroidal melanoma.
CASE DESCRIPTION
A 31-year-old man went to the clinic because of photopsias and vision loss in his right eye. On fundoscopy of the right eye, a choroidal mass with an associated retinal detachment was found near the inferotemporal vascular arcade. Multimodal imaging was performed and diagnosis of choroidal melanoma was made. Metastatic workup ruled out systemic extension. The patient underwent pars plana vitrectomy for endoresection of the lesion. During the application of laser under air, he started complaining of chest pain and dyspnea. He presented signs of supraventricular tachycardia, tachypnea, hypotension and oxygen desaturation. He was managed with orotracheal intubation, bronchodilators and vasopressor support, and stabilization was achieved. He was discharged 2 days after with no sequalae. After 1-year of follow-up, the patient has a visual acuity of counting fingers and no signs of tumor recurrence or systemic extension.
CONCLUSIONS
Although rare, vitreoretinal surgeons should be aware of this potentially fatal complication and take steps to prevent it.
