Summary
A rare case of vision loss in an aphakic patient was resolved by a laser procedure. This hyaloideocapsular block syndrome, occurring 16 years post-cataract surgery, improved vision and corrected myopia.
Area of Science:
- Ophthalmology
- Surgical Case Reports
Background:
- Cataract surgery, specifically extracapsular cataract extraction (ECCE) without intraocular lens (IOL) implantation, can lead to long-term complications.
- Late-onset visual disturbances in aphakic patients require thorough investigation to identify the underlying cause.
Observation:
- An 80-year-old female patient experienced a significant myopic shift and reduced visual acuity 16 years after ECCE without IOL.
- Ophthalmic examination revealed a milky fluid accumulation between the posterior lens capsule and the anterior hyaloid membrane, indicative of a hyaloideocapsular block.
Findings:
- A neodymium:yttrium-aluminium-garnet (Nd:YAG) laser hyaloidotomy was successfully performed to release the trapped fluid into the vitreous cavity.
- Immediate resolution of the myopic shift and improvement in visual acuity were observed post-procedure.
Implications:
- This case highlights a previously unreported late-onset hyaloideocapsular block syndrome following ECCE without IOL.
- Nd:YAG laser hyaloidotomy is an effective treatment for this specific complication, restoring visual function.
- Ophthalmologists should consider this rare syndrome in the differential diagnosis of vision changes in long-term aphakic patients.

01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:21Hyperosmolar Hyperglycemic State
Hyperosmolar Hyperglycemic State, or HHS, is a serious and life-threatening complication of type 2 diabetes mellitus. It is characterized by three main features: severe hyperglycemia, profound dehydration, and elevated serum osmolality, all occurring without significant ketoacidosis.HHS typically develops in older adults or individuals with limited access to fluids. This may result from illness, cognitive impairment, or medications such as diuretics or corticosteroids. These factors reduce...
01:29Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
