Primary intraocular lymphoma (PIOL) is a rare and aggressive cancer that develops within the eye. It is a subtype of primary central nervous system lymphoma (PCNSL) that mostly affects the retina, vitreous, or optic nerve head. PIOL is most...
Primary congenital glaucoma (PCG) is a rare but severe type of glaucoma that appears at birth or develops soon after. It is distinguished by abnormal development of the eye's drainage system, specifically the trabecular meshwork and Schlemm's canal, which...
What is Primary Acquired Nasal Duct Obstruction?
Primary Acquired Nasolacrimal Duct Obstruction (PANDO) is a condition characterized by a blockage in the nasolacrimal duct, which drains tears from the eye into the nasal cavity. This obstruction can cause excessive tearing...
Presbyopia is a common age-related condition that impairs the eye's ability to focus on nearby objects. Presbyopia, which typically appears around the age of 40, is caused by the gradual hardening of the eye's natural lens and the weakening...
Post-surgical glaucoma, also known as secondary glaucoma after ocular surgery, is a condition characterized by elevated intraocular pressure (IOP) that develops as a result of eye surgeries such as cataract extraction, corneal transplantation, or vitreoretinal procedures. If not treated...
What is posterior uveitis?
Posterior uveitis is an inflammatory condition that affects the choroid, retina, and optic nerve head. This condition is part of a larger group of diseases known as uveitis, which is defined by inflammation of the uveal...
A posterior subcapsular cataract (PSC) is a type of cataract that develops at the back of the lens, immediately in front of the posterior capsule. This specific location has a significant impact on vision, often more than other types...
Posterior scleritis is a rare inflammatory condition that affects the posterior segment of the sclera, the eyeball's white, fibrous outer layer. Unlike anterior scleritis, which affects the front part of the sclera and is more visible, posterior scleritis affects...
What is Polychromatic Cataract?
Polychromatic cataract is a rare but intriguing type of cataract in which multiple colors appear within the lens opacity. Polychromatic cataracts, as opposed to typical cataracts, which usually appear as a cloudy or opaque area within...
Pleomorphic adenoma, also known as benign mixed tumor, is the most common benign neoplasm in the lacrimal gland. The lacrimal gland, located in the upper outer region of the orbit, produces tears to lubricate and protect the eye. Pleomorphic...
Maintaining good vision is essential to our daily lives, yet many of us take our eye health for granted until problems arise. With the increasing prevalence of screen time and the aging population, concerns about preserving eyesight are more...
In our increasingly hectic lives, stress has become an almost inevitable part of the daily routine. Whether it’s work deadlines, family responsibilities, or unexpected challenges, stress can creep into every aspect of life. While many people are aware of...
Vision is one of the most vital senses, yet its care is often overlooked until problems arise. While genetics and age play significant roles in eye health, the impact of nutrition is equally critical. What you eat directly affects...
What is Pinguecula?
Pinguecula is a common, harmless ocular condition characterized by a yellowish, slightly raised thickening of the conjunctiva, the clear tissue that covers the white part of the eye and the inner surface of the eyelid. This lesion...
Pigmentary glaucoma is a type of secondary open-angle glaucoma defined by the dispersion of pigment granules within the eye, which can obstruct the drainage system (trabecular meshwork) and cause increased intraocular pressure (IOP). This high pressure can damage the...
What is photophobia?
Photophobia, also known as light sensitivity, is a condition characterized by excessive sensitivity to light. Individuals with photophobia feel discomfort or pain in their eyes when exposed to light sources such as sunlight, fluorescent lights, or even...
Phacoanaphylactic endophthalmitis is a rare and severe type of intraocular inflammation that occurs when lens proteins are exposed to the immune system, usually as a result of trauma or surgical procedures like cataract extraction. When the lens capsule ruptures,...
Persistent Fetal Vasculature (PFV), formerly known as persistent hyperplastic primary vitreous (PHPV), is a congenital eye condition caused by the inability of the fetal hyaloid vascular system to regress. This vascular system normally feeds the developing lens and vitreous...
As parents explore options to correct their children's vision, contact lenses often emerge as an appealing alternative to traditional eyeglasses. The idea of providing children with the freedom to engage in physical activities without the hindrance of glasses is...
In today's digital age, our eyes are exposed to more screens than ever before—smartphones, computers, tablets, and televisions dominate our daily lives. Along with this increased screen time comes growing concern about the potential harm of blue light emitted...
In a world increasingly dominated by digital screens, our eyes are constantly under strain, leading to a surge in vision-related problems. From the classroom to the workplace, and even at home, the average person spends a significant portion of...
Periorbital cellulitis, also known as preseptal cellulitis, is an infection that affects the eyelid and surrounding skin but does not spread beyond the orbital septum. This condition is most commonly seen in children, but it can occur at any...
A penetrating eye injury is a severe ocular condition in which a foreign object pierces the eye and damages its internal structures. This type of injury can affect the cornea, sclera, lens, retina, and even the optic nerve, causing...
Pediatric glaucoma is a rare but serious eye condition that occurs in infants, children, and adolescents. It is distinguished by elevated intraocular pressure (IOP), which can damage the optic nerve, resulting in vision loss and possibly blindness if not...
Orbital rhabdomyosarcoma (RMS) is a malignant neoplasm that develops from skeletal muscle progenitors, primarily affecting children and adolescents. It appears in the soft tissues of the orbit, causing progressive symptoms such as proptosis (eye bulging), ptosis (drooping eyelid), and...
Orbital pseudotumor, also known as idiopathic orbital inflammation (IOI), is a non-cancerous inflammatory condition that affects the tissues of the orbit, the bony cavity that holds the eye. This condition is distinguished by a sudden onset of inflammation that...
Orbital metastatic carcinoma is the spread of cancer from a primary site elsewhere in the body to the orbit, the bony cavity containing the eye. This condition is uncommon, accounting for only a small percentage of orbital tumors, but...
