Presumed Melanocytoma-Associated Choroidal Neovascular Membrane with Hemorrhage Successfully Treated with Intravitreal Aflibercept Injections.

A patient presented with melanocytoma and associated choroidal neovascular membrane with hemorrhage involving the macula. The patient was treated with monthly aflibercept (Eylea) injections with significant improvement of best corrected visual acuity. In this report, we explore the development of a choroidal neovascular membrane (CNVM) formation in a patient with melanocytoma and the effect of intravitreal aflibercept (Eylea) on disease course. Case report study used patient data obtained from examination and imaging. The patient was treated with monthly intravitreal aflibercept injections leading to complete resolution of CNVM and hemorrhage, with significant improvement of best corrected visual acuity. Awareness and proper monitoring for the sequelae of melanocytoma are important for early detection and prevention of visually threatening outcomes. In cases of melanocytoma-associated CNVM formation with large subretinal hemorrhage, intravitreal aflibercept can be an effective tool for inducing CNVM regression and allowing improvement of visual acuity.

Primary and secondary focal choroidal excavation morphologic phenotypes, associated ocular disorders and prognostic implications.

AIMS: To characterise and classify the morphological, clinical and tomographic characteristics of focal choroidal excavation (FCE) lesions to determine their prognostic implications. METHODS: 36 eyes with FCE (32 patients) underwent multimodal imaging, including spectral domain optical coherence tomography and fundus autofluorescence. FCE lesions were classified into three subtypes: (1) type 1: myopic (central choroidal thickness: <100 µm), (2) type 2: suspected congenital (central choroidal thickness: 100-200 µm, without associated chorioretinal pathology) and (3) type 3: secondary or acquired (central choroidal thickness: >200 µm, with associated chorioretinal pathology). RESULTS: 80.6% of eyes were followed longitudinally (26.8±18.8 months). There were 9 type 1 FCEs (myopic), 8 type 2 FCEs (U-shaped, congenital) and 19 type 3 FCEs (V-shaped, secondary). Type 2 FCEs trended towards larger maximum widths (p=0.0563). Type 3 FCEs were associated with central serous chorioretinopathy or pachyvessels (47.4%), but were also seen in pattern dystrophy, geographic atrophy, inactive choroiditis, torpedo maculopathy and adult-onset vitelliform dystrophy. Choroidal neovascular membranes (CNVMs) were more prevalent in type 3 FCE (41.2% compared with 11.1% for type 1 FCE, p=0.251, and 0% for type 2 FCE, p=0.043). CONCLUSIONS: The FCE types, stratified by central choroidal thickness, demonstrated distinct morphological characteristics and associated findings. The classification scheme held prognostic implications as type 3 FCE with V shapes were associated with other chorioretinal conditions and were more likely to develop CNVM.

Endophthalmitis Caused by Kocuria Kristinae.

Kocuria is an anaerobic, Gram-positive bacterium, which has been rarely reported to cause endophthalmitis following cataract surgery, intravitreal injections, penetrating ocular trauma, and also secondary to endogenous sources. Visual prognosis is often guarded, with no previous cases reporting a final visual acuity better than 20/60. We describe a young female patient who developed culture-proven Kocuria kristinae endophthalmitis associated with a traumatic scleral rupture. Visual acuity at 2 months of follow-up improved from light perception to 20/50 after treatment with intravitreal antimicrobial therapy and pars plana vitrectomy.

The Expanded Clinical Spectrum of Coxsackie Retinopathy.

The authors present two cases of coxsackie retinopathy that presented with the classic findings of acute outer retinal disruption that evolved to an outer retinal scar. In these two cases, the classic lesions displayed an extramacular distribution. The authors provide detailed multimodal imaging in both cases highlighting the nature of the lesions. It is important to consider coxsackie virus infection in the differential diagnosis of extramacular lesions with outer retinal disruption. The term "unilateral acute idiopathic maculopathy" should be replaced with "coxsackie retinopathy" to better align with the expanded clinical spectrum and the known etiology of this disorder.

Choroidal Nevus with Retinal Invasion in 8 Cases.

PURPOSE: Choroidal nevus can cause overlying chronic retinal pigment epithelium (RPE) degenerative features, but frank retinal invasion is exquisitely rare. PROCEDURES: This is a retrospective review of 8 cases of choroidal nevus with retinal invasion with evaluation of clinical and imaging features. RESULTS: At the time of diagnosis of choroidal nevus with retinal invasion, mean patient age was 65 years. Mean tumor basal diameter was 7 mm, and mean thickness was 2.3 mm. Retinal invasion was ophthalmoscopically visible in all eyes. Related features included drusen (n = 4/8) and RPE fibrous metaplasia (n = 2/8). Overlying lipofuscin, subretinal fluid, RPE detachment, and retinal edema were absent. On B-scan ultrasonography, the lesion was dome-shaped (n = 7/7) and echo-dense (n = 6/7). Optical coherence tomography demonstrated outer retinal invasion (n = 8/8) with additional inner retinal invasion (n = 3/8). The tissue was hypoautofluorescent at the site of invasion (n = 6/7). Over a mean follow-up of 40 months, tumor enlargement was detected in 2 eyes and managed with observation (< 1 mm enlargement) or plaque radiotherapy (5 mm enlargement). Nevus hypoautofluorescence was correlated with nevus stability (p = 0.035). CONCLUSION: Retinal invasion of the choroidal nevus is rare. In this series of 8 cases, only 1 demonstrated transformation to melanoma over a mean interval of 40 months. Long-term monitoring of such lesions is warranted.

A Case of Terson-Like Syndrome in a Patient with Viral Meningoencephalitis.

The proposed mechanism of Terson's syndrome is increased intracranial pressure that leads to dilation of the retrobulbar optic nerve and compression of the central retinal vein. Terson's syndrome has been associated with many conditions that increase intracranial pressure such as venous sinus thrombosis, Moyamoya disease, leukemia, direct head trauma, and intraocular hemorrhage related to shaken baby syndrome. We present a novel case of a patient with recent viral prodrome found to have papilledema and multilayered retinal hemorrhages consistent with Terson syndrome. Computed tomography and magnetic resonance venography of the brain did not reveal any subdural, subarachnoid, or intracranial hemorrhages. However, cerebrospinal fluid analyses were significant for increased opening pressure and elevated protein levels, which were suggestive of viral meningoencephalitis. We describe this case as a Terson-like syndrome because the etiology of intraocular hemorrhage is increased intracranial pressure. However, this case does not fit the traditional presentation of Terson's syndrome as the intracranial pressure is secondary to meningeal inflammation instead of subdural, subarachnoid, or intracranial hemorrhage. We strongly feel that it is important for physicians to be aware of the link between viral meningoencephalitis and retinal conditions such as Terson-like syndrome because it can facilitate rapid diagnosis and treatment.

Rate of Spontaneous Resolution of Congenital Nasolacrimal Duct Obstruction Prior to Scheduled Probing in Children Older Than 1 Year.

The authors conducted a 10-year retrospective review of all patients within one physician's practice to determine the frequency of spontaneous resolution of congenital nasolacrimal duct obstruction in children older than 1 year during the interval between scheduling and date of probing. This review found 4.4% of eyes resolved within an average interval period of 39 days. [J Pediatr Ophthalmol Strabismus. 2019;56:e31-e33.].

Performance validity testing in children and adolescents: A descriptive study comparing direct and embedded measures.

Effort testing is a standard element in adult neuropsychological assessment. Research examining performance validity tests (PVTs) has focused on adults. The purpose of this descriptive study was to examine direct and embedded PVTs in children and adolescents. The Test of Memory Malingering (TOMM), a stand-alone PVT, was compared to two embedded measures of effort: California Verbal Learning Test-Children's Version/Second Edition (CVLT-C/II) Recognition Discriminability and Reliable Digit Span (RDS). The sample consisted of 119 children and adolescents referred for outpatient assessment. Cut-off scores used for PVTs were based on previous studies. Results revealed 3/119 failures on the TOMM, 14/119 failures on the RDS, and 34/119 failures on the CVLT-C/II. There was a significant difference between failures on the TOMM and the RDS, as well as between failures on the TOMM and the CVLT-C/II and the RDS and the CVLT-C/II. The results of this study demonstrate that PVTs commonly used with adults may require modifications, including adjusted cut-off scores, to be appropriate with children and adolescents. Results of this study also suggest that relying on more than one measure likely provides the most utility.

Focal Choroidal Excavation Expansion Following Treatment of Associated Choroidal Neovascular Membrane.

The authors describe a case of a previously unreported phenomenon of focal choroidal excavation (FCE) expansion, in absence of inflammation, due to treatment of an associated choroidal neovascular membrane (CNVM). A patient with new type 2 CNVM, treated during 43 months of follow-up with aflibercept, experienced significant expansion of an FCE with conversion from nonconforming to conforming type. FCE is part of the pachychoroid spectrum and the regression of an associated CNVM during aflibercept treatment as seen in the authors' patient may elucidate the pathogenesis of some forms of focal choroidal excavation and their evolution over time.

ENDOPHTHALMITIS AFTER PARS PLANA VITRECTOMY: Efficacy of Intraoperative Subconjunctival Antibiotics.

PURPOSE: To examine rates of acute infectious endophthalmitis after pars plana vitrectomy (PPV) in eyes that received intraoperative subconjunctival antibiotics versus eyes that did not. METHODS: A retrospective, nonrandomized, comparative case series of 18,886 consecutive cases of transconjunctival 23-, 25-, and 27-gauge PPV over a 5-year period was performed. The impact of prophylactic intraoperative subconjunctival antibiotics on the development of acute infectious postoperative endophthalmitis was examined. RESULTS: Of 18,886 cases of PPV, 14,068 (74.5%) received intraoperative subconjunctival antibiotics, whereas 4,818 (25.5%) did not. Sixteen cases (0.085%, 1/1,176) of post-PPV endophthalmitis were identified. The incidence of endophthalmitis in eyes that received subconjunctival antibiotics was 0.078% (11/14,068 cases, 1/1,282), whereas the incidence in those that did not receive subconjunctival antibiotics was 0.10% (5/4,818 cases, 1/1,000). No statistically significant difference was identified in the incidence of endophthalmitis between those that received subconjunctival antibiotics and those that did not (P = 0.598). Microbial culture was performed in 11 cases with 6 culture-positive cases (5/8 cases that received subconjunctival antibiotics and 1/3 cases that did not). CONCLUSION: Prophylactic subconjunctival antibiotics were not associated with a significantly reduced rate of post-PPV endophthalmitis. With consideration of emerging multidrug-resistant bacteria, routine prophylactic subconjunctival antibiotics may not be justified.

Retinal and Preretinal Hemorrhages in a Patient Receiving Hyper-CVAD Chemotherapy for T-Cell Acute Lymphoblastic Leukemia.

Hyperfractionated cyclophosphamide, vincristine, adriamycin, and dexamethasone (Hyper-CVAD) is an important chemotherapeutic regimen for acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma. We present a case of a 23-year-old male with T-cell ALL and visual acuity of 20/20 in the right eye and 20/25 in the left eye who developed significant changes in his vision after starting Hyper-CVAD therapy. The patient initially presented with cotton wool spots in the fundus shortly after starting the regimen. After going through the induction phase of chemotherapy, he had a sudden decline in his vision to light perception in the left eye. Posterior segment exam revealed retinal ischemia and multilayered hemorrhages in both eyes as well as a large preretinal hemorrhage obscuring the fovea in the left eye. Labs associated the appearance of these hemorrhages with a significant decrease in hemoglobin and a platelet count of 5 K/µL. A Nd:YAG laser applied in the left eye at the posterior hyaloid face allowed blood to drain into the vitreous cavity and brought the patient's visual acuity back to baseline. Hyper-CVAD is an aggressive chemotherapy regimen that can cause severe thrombocytopenia secondary to myelosuppression. Frequent retinal evaluations and timely intervention is advisable in these cases as extensive intraretinal hemorrhages may cause irreversible damage.

Incontinentia pigmenti in a child with suspected retinoblastoma.

BACKGROUND: Incontinentia pigmenti is a rare X-linked dominant syndrome caused by mutation in the NEMO/IKKgamma gene, and characterized by a spectrum of cutaneous, ocular, neurologic and dental abnormalities. In the eye, findings include retinal vascular non-perfusion, occasionally with traction retinal detachment, retinal fibrosis, and retinal pigment epithelium defects. These findings can resemble retinoblastoma, especially when vitreoretinal fibrosis produces leukocoria. CASE REPORT: A 2-month-old girl born full-term presented with leukocoria, suspicious for retinoblastoma. She was found to have an ischemic retrolental fibrovascular retinal detachment. In addition, there was linear cutaneous hyperpigmentation, diagnostic of incontinentia pigmenti. CONCLUSIONS: Retinoblastoma can be a challenge to diagnose. There are numerous simulating lesions that can present with leukocoria and retinal detachment, including incontinentia pigmenti. Recognition of the cutaneous features of incontinentia pigmenti contributes to early detection of related ophthalmologic, neurologic and dental abnormalities.
