Globular and Fibrous Proteins02:21

Globular and Fibrous Proteins

Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Globular Proteins

In organisms, proteins are the most abundant macromolecules. They act as the building blocks of life and play various crucial roles in the body. Proteins can be broadly classified into two distinct subtypes based on their shape and solubilities: globular proteins and fibrous proteins.
Globular proteins serve many important physiological functions, such as acting as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be soluble in the aqueous...
Accessory Structures of the Eye01:17

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Anatomy of the Eyeball01:20

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
Polytene Chromosomes02:04

Polytene Chromosomes

Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also regularly...

Area of Science:

  • Ophthalmology
  • Corneal Disorders
  • Genetics

Background:

  • Keratoglobus is a rare, noninflammatory corneal thinning disorder.
  • Characterized by generalized thinning and globular protrusion of the cornea.
  • It can occur in congenital and acquired forms, potentially linked to connective tissue disorders.

Purpose of the Study:

  • To review the aetiological factors, differential diagnosis, histopathology, and management options for keratoglobus.
  • To highlight the challenges in managing this rare corneal condition.
  • To discuss current understanding and gaps in knowledge regarding keratoglobus.

Main Methods:

  • Literature review of existing studies on keratoglobus.
  • Analysis of clinical presentations and associated syndromes.
  • Examination of conservative and surgical management strategies.

Main Results:

  • Keratoglobus presents with progressive vision loss due to irregular corneal topography and increased fragility.
  • Similarities with keratoconus suggest shared, yet unclear, aetiopathogenesis.
  • Management is challenging, with various surgical procedures attempted without a definitive standard.

Conclusions:

  • The exact genetics and pathogenesis of keratoglobus remain largely unknown.
  • Effective visual rehabilitation and tectonic stability are difficult to achieve.
  • Further research is needed to establish definitive diagnostic and management protocols for keratoglobus.
