Improvements in retinal imaging have recently elucidated structural patterns in the development of macular edema, particularly involving the inner nuclear layer. Here, the authors describe two cases of isolated inner nuclear layer cystic changes in the phakic fellow eye of patients with pseudophakic cystoid macular edema. Both cases improved with treatment of their fellow eye and resolution of contralateral macular edema.

Article Synopsis
  • The study investigates how pseudophakic cystoid macular edema (CME) evolves and its correlation with retinal changes detected through imaging techniques like SD-OCT and fluorescein angiography.
  • It involves a detailed analysis of 39 patients over 6 months, focusing on structural features such as cystic changes in the inner nuclear layer (INL) and outer plexiform layer (OPL), and the effects of treatment with glucocorticoids.
  • Findings suggest that CME progresses from INL changes to combined INL and OPL involvement, often involving subretinal fluid, indicating disease activity, particularly within the early postoperative period.

Ocular histoplasmosis syndrome (OHS) is a chorioretinal disorder with a distinct fundus appearance that is commonly found in regions endemic for Histoplasma capsulatum. Choroidal neovascularization (CNV) secondary to OHS is considered one of the principal causes of central vision loss among young adults in endemic areas. Although there is no consensus regarding its pathogenesis, evidence points to Histoplasma capsulatum as the most probable etiology.

Recently, many authors have propagated the notion that a specific form of "microcystic macular edema" occurs in patients with optic neuritis and optic atrophy of various etiology and is due to retrograde synaptic degeneration. The finding is isolated to the inner nuclear layer on spectral-domain optical coherence tomography in most cases, and is present in a parafoveal, circumferential, and central macular distribution. This perspective critically reviews the evidence and suggests that inner nuclear layer cystoid changes are an early and nonspecific indicator of typical cystoid macular edema of any cause, and that the finding is likely not a distinct entity.

A novel case description of an isolated unilateral submacular choroidal varix simulating chorioretinal folds and inducing metamorphopsia in a 74-year-old phakic Caucasian man. Posterior segment examination revealed focal choroidal elevations corresponding to a deep, large choroidal vessel in the inferotemporal subparafoveal region. Fundus photography demonstrated a pigment epithelial detachment-like elevation inferior to the fovea, continuous with the course of a large choroidal vessel.

Since its original description in 1908, Coats disease has been recognized as an idiopathic cause of severe vision loss with a remarkable diversity in clinical presentation and morphology. Key clinical and imaging variables are helpful in differentiating Coats disease from life-threatening malignancies, and proper management revolves around a thorough knowledge of the differential diagnosis. Despite significant advancement in scientific understanding of the disease process and clinical spectrum, the underlying etiology remains obscure, and both primary and secondary forms are recognized.
