Scleral Thickness as a Risk Factor for Central Serous Chorioretinopathy and Pachychoroid Neovasculopathy.

In the pathophysiology of central serous chorioretinopathy (CSC), scleral changes inducing increased venous outflow resistance are hypothesized to be involved. This work aims to investigate anterior scleral thickness (AST) as a risk factor for pachychoroid disorders. A randomized prospective case-control study was performed at the Ludwig Maximilians University, Department of Ophthalmology.

Posterior Segment Involvement in Infantile Nephropathic Cystinosis - A Review.

Cystinosis is a rare lysosomal storage disease with a prevalence of 1 : 100 000 - 1 : 200 000 cases. It is caused by biallelic mutations in the CTNS gene, which encodes cystinosin, that transport cystine out of the lysosomes. Due to its dysfunction, cystine crystals accumulate in the lysosomes and ultimately cause apoptosis of the cell.

Long-Term Results of Adjunct Autologous Platelet-Rich Plasma in Lamellar Macular Hole Surgery Showing Lasting Restoration of Foveal Anatomy.

The aim of this study was to evaluate the long-time results of highly concentrated autologous platelet-rich plasma (PRP) used as an adjunct in lamellar macular hole (LMH) surgery. Nineteen eyes of nineteen patients with progressive LMH were enrolled in this interventional case series, on which 23/25-gauge pars plana vitrectomy was performed and 0.1 mL of highly concentrated autologous platelet-rich plasma was applied under air tamponade.

Corneal Manifestation in Patients with Infantile Nephropathic Cystinosis.

Nephropathic cystinosis is a rare autosomal recessive disease caused by mutations in the CTNS gene. This causes dysfunction of cystinosin, a protein that transports cystine out of lysosomes, causing cystine crystals to accumulate in cells in most organ systems. While renal complications predominate in the early forms of cystinosis, corneal crystal accumulation will inevitably manifest in all patients.

Progression of Pachychoroid Neovasculopathy into Aneurysmal Type 1 Choroidal Neovascularization or Polypoidal Choroidal Vasculopathy.

Purpose: To describe the progression of pachychoroid neovasculopathy (PNV) into pachychoroid aneurysmal type 1 choroidal neovascularization (PAT1)/polypoidal choroidal vasculopathy (PCV).

Design: Retrospective longitudinal cohort study.

Subjects: Patients diagnosed with PNV with a follow-up of ≥2 years.

Pachychoroid disease and its association with retinal vein occlusion: a case-control study.

The development of a retinal vein occlusion (RVO) is multifactorial. This study investigates pachychoroid as a risk factor for RVO or as an entity sharing common pathophysiology with RVO. A database screening at the University Eye Hospital, Ludwig-Maximilian University Munich, Germany was performed for patients diagnosed with central or branch RVO (CRVO/BRVO).

Vanishing pachy-choroid in pachychoroid neovasculopathy under long-term anti-vascular endothelial growth factor therapy.

Background: To investigate the diagnostic value of choroidal thickness in the definition of pachychoroid neovasculopathy (PNV), especially in eyes treated with anti-vascular endothelial growth factor (VEGF) therapy.

Methods: Twenty-two consecutive eyes of 11 patients with uni- or bilateral PNV were analyzed. Anti-VEGF treatment was correlated with changes in choroidal thickness on enhanced depth imaging optical coherence tomography.

Subthreshold laser therapy with a standardized macular treatment pattern in chronic central serous chorioretinopathy.

Purpose: There is an ongoing controversial debate about the effectiveness of laser treatments in chronic central serous chorioretinopathy (cCSC). We performed a prospective non-randomized interventional study to learn about the effects of a subthreshold laser treatment (Topcon Endpoint Management™, Topcon Healthcare Inc., Tokyo, Japan) in patients with cCSC.

Pachychoroid Neovasculopathy Disguising as Age-Related Macular Degeneration Treated by Spironolactone and Anti-VEGF Combination Therapy.

Nonresponse of neovascular age-related macular degeneration (nAMD) to anti-vascular endothelial growth factor (anti-VEGF) therapy can often be attributed to misdiagnosis, and pathologies mimicking AMD might require different therapeutic concepts. In the following, we want to outline a case of presumed nAMD which revealed to be pachychoroid neovasculopathy (PNV) and was successfully treated by the addition of spironolactone. A 67-year-old female patient was referred for nonresponse of nAMD on her left eye after 29 intravitreal injections of aflibercept with no complete resolution of subretinal fluid.

Biotinidase deficiency: A treatable cause of hereditary spastic paraparesis.

Objective: To expand the genetic spectrum of hereditary spastic paraparesis by a treatable condition and to evaluate the therapeutic effects of biotin supplementation in an adult patient with biotinidase deficiency (BD).

Methods: We performed exome sequencing (ES) in a patient with the clinical diagnosis of complex hereditary spastic paraparesis. The patient was examined neurologically, including functional rating scales.

Ranibizumab non-response in pachychoroid neovasculopathy: Effects of switching to aflibercept.

Non-response to intravitreal ranibizumab represents a frequent problem in pachychoroid neovasculopathy (PNV). To investigate the effectivity of switching to aflibercept, the database of the Ludwig Maximilians University, Munich, was screened for patients fulfilling the following inclusion criteria: (i) diagnosis of PNV; (ii) inadequate response to ≥ 3 ranibizumab injections, in spite of monthly dosing, defined as persistence of subretinal-fluid four weeks after the last ranibizumab injection; (iii) resulting switch to aflibercept administered as three monthly injections. Primary outcome measure was percentage of eyes with a dry macula four weeks after the third aflibercept injection.

Response of neovascular central serous chorioretinopathy to an extended upload of anti-VEGF agents.

Purpose: To determine the anatomical and functional outcomes of an extended 6-month intravitreal anti-vascular endothelial growth factor (anti-VEGF) upload in choroidal neovascularization (CNV) secondary to chronic central serous chorioretinopathy (CSCR).

Methods: A retrospective database analysis was performed applying the following inclusion criteria: (1) diagnosis of CSCR, (2) diagnosis of secondary CNV, and (3) treatment of at least six consecutive injections of anti-VEGF. Outcome measures included the change of central retinal subfield thickness, remodeling of the pigment epithelium detachments, and change in visual function.
